Working with CiviCRM every day at the Wikimedia Foundation has given me a real appreciation for the people behind the system. As a user, I know how much we rely on Civi to support our work and how important it is to have people we can turn to when we need help!
What I appreciate most about the Civi team is their willingness to listen, help us work through challenges, and understand things from our perspective as users. Sometimes, we know what we need to accomplish but aren’t quite sure how to get there. Having people who are willing to explore solutions with us and share their knowledge makes such a difference.
Attending my third CiviCamp in Paris made me appreciate this even more. Beyond the sessions and training, one of the best parts was getting to know the people behind the technology and connecting with other users. There’s something special about putting faces to names, sharing experiences, talking through common challenges, and learning from one another. You leave with new ideas, but also with a stronger connection to the people who make this community what it is.
I also loved being able to bring what I learned straight back to my team. During the event, we needed help, and that’s exactly what happened! Apparently, all you need to do is ask or sit on the hallway floor looking lost from so many failed attempts, and voilà, you shall receive! Haha!
My colleague and I were able to solve a couple of Phabricator tasks that had been open for quite some time and create a new view that displays direct mail activities right in a donor’s contact summary. This makes it easier for my team to find important donor information without navigating multiple screens. I also created SearchKit documentation to help with onboarding and support future reporting.
For me, this was a great example of how learning together can lead to practical improvements in our everyday work. Sometimes, we don’t need to reinvent the wheel. We just need to discover what’s possible, share what we know, and have the right people around us to help make it happen.
That’s what makes Civi special to me. It’s not just the technology, but the people who give their time, share their knowledge, and genuinely want to help others succeed.
A big thank you to the Civi team and everyone in the community for your kindness and support. I'm looking forward to the next event to reconnect with familiar faces, meet new people, and see what we can learn and accomplish together!

An exclusive early look at Apple’s new touchscreen MacBook Pro—the computer Apple said would never happen.

It’s a bright
day in Cupertino. Apple’s new CEO strolls to an outdoor seating area within the company’s otherworldly
ring-shaped headquarters
and pulls up a chair. An employee notes the angle and asks if he minds the sun. John Ternus doesn’t mind at all.
Nearly two months into his tenure, he’s been busy. While the tech world buzzes about AI agents and the upcoming IPO of a company reporting spectacular losses, Ternus’ leadership of a ridiculously profitable firm has so far been defined by a sequence of significant launches—the long-awaited
foldable iPhone
, a
household device
that can control digital appliances, new
Mac Minis
, and AirPods. Intentionally or not, all that activity sends a message that, even as AI dominates the public imagination, hardware products still rule.

Ternus doesn’t endorse that take, but he doesn’t object when I suggest it. “We’ve been working on these products for quite some time,” he says. “It feels like everyone here is just kind of riding high right now, enjoying it.”
I ask if Apple is about to break a long-imposed taboo and introduce a Macintosh with a touch screen.
Ternus beams. “Who knew?”
We are referring to the new MacBook Pro with PROLED XDR Display that Apple is releasing today at an event in Los Angeles. It’s got a mighty M5 Pro or M5 Max chip and a show-stopping tandem OLED screen. (A tandem screen has multiple light-emitting layers, producing more dramatic contrasts.) But its most conspicuous feature is one that’s been deeply woven into iPhones, iPads, and even Apple Watches for years but not Apple’s laptops: a touch display. After years of resistance, a Mac screen has finally gone digital. As in fingers.
This turnaround is a big deal to Apple fans. Ternus shrugs off the drama. “The Mac is first and foremost an indirect input device, built around the trackpad and keyboard. But I think there’s times when it’s comfortable and handy to have touch.”
Ternus and Apple want to make sure that the Mac faithful don’t panic that the 42-year-old franchise is losing its identity to Apple’s gangbusters mobile products. “We needed to get to a point where adding touch didn’t make the product lesser in any way. It didn’t make it heavier. It didn’t make it thicker. That came together with the OLED screen, the best display we’ve ever put into a Mac,” Ternus told me. “All of these things, and, oh yeah, it has touch as well.”

Apple has a
long history of refusing to implement certain desirable features, only to pivot when it feels the time is right. Steve Jobs once proclaimed iPods would never do video, until they did. He also
once said
“no one’s going to buy” a jumbo-size phone—and then Apple released a supersized iPhone 6. Then there was that time Jobs declared styluses inappropriate for tablets. Now the Apple Pencil works with iPads and the brand-new
Duo
.
The 2026 MacBook Pro instantly qualifies as the canonical example of this switcheroo. Apple executives had been on record regarding touch on PCs as a misbegotten idea. Never mind that just about every PC maker not headquartered in Cupertino has implemented touch on their laptops. And customers of Microsoft, Dell, Acer, Lenovo, and HP have snapped them up. Clearly, people wanted touch on their laptop displays. Even toddlers knew it—put some rug rats in front of a computer and their little arms shoot straight to the screen in futile attempts to swipe and scroll as they do on their iPads. People were baffled why Apple—the pioneer in touch displays since the iPhone—was so steadfast in its rejection.
In 2015, while doing a story about a new iMac, I pressed Phil Schiller, then the senior vice president of worldwide product marketing, on this very question. Usually, top Apple executives field such queries with cryptic remarks. In this case, Schiller began a filibuster. “I’m going to get a little bit philosophical,” he said, then launched into what I later described as the Grand Unified Theory of Apple Hardware.
He explained that every Apple hardware product—the Watch, iPad, iMac, MacBook—is basically a computer and a piece of glass. Each one has a specific function. And each one has an interface appropriate to the hardware. Multitouch is fine for products like the iPhone, he said—but not the Macintosh. He provided two reasons: ergonomics and the software interface.
“From the ergonomic standpoint, we have studied this pretty extensively, and we believe that on a desktop scenario, where you have a fixed keyboard, having to reach up to do touch interfaces is uncomfortable,” he told me.
As for the interface, Schiller argued that Apple’s two main operating systems were built on different design principles. The iPhone and iPad’s iOS was multitouch from the get-go, and didn’t use macOS conventions that require precision, such as cursors and tiny boxes to close windows. “These two worlds are different on purpose, and that’s a good thing—we can optimize around the best experience for each of those and not try to mesh them together into a least-common-denominator experience,” he told me.
A year later, when Apple introduced a MacBook Pro with the ill-fated “touch bar”—a dynamic strip of virtual function keys above the keyboard’s top row—Schiller
doubled down
on the view that touch should never find its way into a Mac display. He said that such a move would mean totally redesigning the menu bar for fingers, and that would clash with the experience of pointer devices like a touchpad or mouse. “You can’t optimize for both,” he said.
To double-check this assumption, Apple conducted user tests with touchscreens on Mac. “What the heck, we could be wrong,” Schiller told me then. “We’ve absolutely come away with the belief that it isn’t the right thing to do. Our instincts were correct.”
When I met with Apple executives Johny Srouji and Greg Joswiak this week to discuss the touchscreen MacBook Pro, you bet I invoked Schiller’s list of concerns. (Apple’s reps chose not to make Schiller, who now holds the title of “Apple Fellow,” available for an interview. In fact, they laughed when I asked.) It wasn’t only Schiller drawing a red line. In 2021, Ternus
told
journalist Joanna Stern, “The Mac is totally optimized for indirect input. We haven’t really felt a reason to change that.”
“Ten years is a very, very long time,” says Srouji, Apple’s chief hardware officer. “Many things have changed, whether it's the display technology, the custom silicon, et cetera.” Eventually, he told me, the confluence of chips, display tech, and software architecture “met our bar.” “I like my engineers to be gated by physics, not imagination or timelines,” he says.
Joswiak, who holds Schiller’s old title of SVP of worldwide marketing, concedes that touch was overdue, at least for users with sophisticated needs. Its pro customers—engineers, scientists, software developers, and media creators—were impatient with Apple for its failure to let them interact directly with the screen. “Most pros own an iPad, and almost every pro owns an iPhone,” Joswiak says. “So this is something that they’re natural with. There’s a generation of young creators and young people using our MacBook Pros that expect to touch.”
Between the lines, Srouji and Joswiak seem to consider their competitors’ touchscreen implementations shabby and lazy. The Apple ethos, as every one of its executives will happily explain to anyone who asks, is an expectation of quality that’s sky-high. “If you’re working on something easy, you’re wasting your time,” says Srouji, who has been at Apple since 2008 and has pretty much driven its innovation by spearheading the company’s charge to custom-build silicon.
“The easy things, I want to outsource,” he continues. “So the custom silicon is hard. The touch is hard. The display is hard. Everything we build is hard.” This swaggering philosophy dates from the Steve Jobs days and, in 2026, stands in contrast to the endgame of the ascendant AI industry, which hopes to turn over the toughest parts of industrial production to superintelligent entities.
Srouji presents Mac touch as a suite of innovations, starting with that screen that Ternus described as the Mac’s best ever. It also involves custom silicon and a rearchitected thermal system to prevent the display from feeling hot when people pinch, stretch, and swipe on it. Srouji contends that current touchscreen laptops suffer from “wobble” when fingers make contact with the display; to minimize this effect, Apple has redesigned the hinge on the MacBook Pro screen to stabilize it.
When I get
a demo of the 16-inch version (as with previous Pros, it’s also available in a 14-inch version), I see what they mean about the display. It’s noticeably dense and bright, and the obsidian blacks are the deepest I’ve seen on a computer screen. In part because the OLED screen doesn’t require backlighting, this MacBook weighs less than its predecessor.

As a pair of Apple managers take the MacBook through its paces, I see how Apple has addressed some of Schiller’s decade-old concerns, like having to redesign the menu bar for fingers. While it looks the same, when you move a finger over a menu item, it expands to allow you to select your choice with precision. Some of the objects on the screen, like the traffic-light buttons that close or hide windows, also get bigger when you touch them.
They show me how the touch tech can handle precision tasks, like color grading in the video editing software DaVinci Resolve, or tweaking a soundtrack on Logic Pro, Apple’s high-end audio workstation. One innovation, not just for pros, is a new gesture to pull down the “Dynamic Island,” that black oval hosting ongoing tasks that has made its way to Mac from iPhone. An expanded version floats on the screen like a widget, enabling easy access to Siri responses and Spotlight search.
But what about greasy fingers messing up the screen? I was told that the new display has an anti-reflective outer coating that will require no more cleaning than your normal non-interactive screen.
Apple clearly hopes that the MacBook Pro launch puts an exclamation point on the burst of product
announcements
that Apple customers are still
absorbing
. For the
foldable
Duo, some customers are impatiently waiting for delivery dates that stretch into January. (Lines were long at Apple stores last Friday, when the device went on sale, and Joswiak personally greeted those who queued up at Apple’s Fifth Avenue store in New York City.)
I ask Srouji whether Apple is making a statement with its
armada
of new products, maybe as a way to say that in a year dominated by AI obsession, Apple is still here. He responds much as his new boss did, contending that Apple is simply sticking to its game plan. “We’re here to build the most amazing products in the world, and we want to ship them when we believe it’s ready and complete,” says Srouji. “That’s the statement we’re making. I think everyone knows we’re here.”
While longtime users will be happy to hear that a Macintosh now has a touchscreen, those with limited budgets will be disappointed. Apple’s current stance—that touch-on-a-Mac display is most appropriate to the “pro” crowd—rationalizes an astronomical price tag: The new MacBook Pro starts at $2,899 for the 14-inch version and $3,399 for the 16-inch model. Financial analyst Neil Cybart, who got an early MacBook Pro briefing, thinks that serious professionals will pay up. “People are in search of value, and that means going for products that leverage technology to improve what they’re doing,” he says.
When I ask Ternus about the timeline, or even the possibility, of seeing touch displays on less exorbitantly priced MacBook Airs and iMacs, he shakes his head. “You’ve been doing this a long time,” he says. “You know I will never tell you anything about our future.”
I don’t know why I bothered to ask. If Ternus said that touch would never happen on a MacBook Air, who would believe him? I’d be back at The Ring a year later, hearing that Apple had finally figured out a way to do it right.

Claude Code burns ~15–20% of your tokens on a 3-word status line
Tested on Linux, Claude Code 2.1.257–2.1.312 (see Tested versions). The binary is not modified (
BUN_OPTIONS=--preload
). An update can silently undo it, so see Verify.
TL;DR
curl -fsSL https://gist.githubusercontent.com/flamerix-ai/c3905705cc4205e5de3011fa2e74efce/raw/no-agent-summary.js -o ~/.local/share/no-agent-summary.js
claude daemon stop --any
BUN_OPTIONS="${BUN_OPTIONS:+$BUN_OPTIONS }--preload $HOME/.local/share/no-agent-summary.js" claude
To make it permanent for every Claude Code process, see
Install
.
The problem
Every ~30 seconds, for every background agent, Claude Code sends that agent's
entire
transcript
to the agent's own model (usually Opus) and asks it to "describe your most recent
action in 3-5 words". The answer only updates the agent's status line in the agents panel; it
never reaches the model or your conversation. There is no setting that turns it off, and since
2.1.232 (August 2026) it has been on by default.
The anomaly was detected by
DRIM
in Claude Code's OpenTelemetry export:
grouping
claude_code.api_request
events by
query_source
showed
agent_summary
costing
more than the main conversation itself
.

, about 1 in 5

part of that spend on Opus
96 %
—
input tokens per output token
≈ 9,000 : 1
—
Spend here means Claude Code's own per-request estimate (
cost_usd
), not an invoice: on a
subscription, what you lose is rate-limit headroom. We are not the only ones who measured it:
#86879
collects four independent
measurements of 18–26 %.
The fix (how it works)
no-agent-summary.js
is a Bun preload (~80 lines of code). It wraps
setTimeout
/
setInterval
;
when a callback's source text contains a summarizer anchor (e.g. the
[AgentSummary] Timer fired
log line), it returns an inert handle instead of arming the timer. Every other timer passes
through untouched. In the OpenTelemetry export the suppressed requests are
claude_code.api_request
events with
query_source = agent_summary
.
Why a timer hook rather than something simpler: the module ships as precompiled Bun bytecode, so
editing its JS text inside the binary changes nothing, and the API client does not go through a
wrapped
globalThis.fetch
. But
Function.prototype.toString
still returns a callback's source
even when it runs from bytecode, so the timer can be recognised by a string inside it. The inert
timer uses exactly 2³¹−1 ms: Node and Bun treat a larger delay as 1 ms, so an "infinite" delay
would fire at once.
Install
Put
no-agent-summary.js
somewhere stable; note its
absolute
path.
Set
BUN_OPTIONS
globally
so every Claude Code process gets it. One of:
# ~/.config/environment.d/50-no-agent-summary.conf (systemd user env; also reaches# user services and timers; applies when the user manager next starts, usually next login)BUN_OPTIONS=--preload /abs/path/no-agent-summary.js
Or a wrapper named
claude
earlier on
PATH
(the
case
keeps it idempotent when one Claude
Code process starts another):
Restart the daemon and every already-running session, then start Claude Code from an
environment that has
BUN_OPTIONS
:
Env
variable
values
effect
CC_AGENT_SUMMARY_MODE
off
(default),
pass
off
suppresses the summary timer.
pass
is the A/B control: loads and logs, arms every timer untouched. Any other value warns on stderr and acts as
off
.
CC_AGENT_SUMMARY_LOG
file path, optional
Appends
preload active mode=… bun=… hooked=…
on load, one line per matched timer (first 20), and an exit count.
CC_AGENT_SUMMARY_MARKER
file path, optional
Overwritten on load with the
preload active …
line.
Nuances
Restart the daemon after install.
The daemon, pty host and pre-warmed
bg-spare
sessions
inherit the environment of the client that started the daemon, so a daemon started before
BUN_OPTIONS
was set keeps spawning unhooked sessions. Hence
claude daemon stop --any
.
Headless runs need it too:
claude -p
, cron, CI, editor integrations.
Platform:
Linux tested, macOS and Windows untested. On Windows the
/$bunfs/
gate most
likely never installs the hook.
A/B:
CC_AGENT_SUMMARY_MODE=pass
loads the hook but arms every timer; the summaries come back, which shows the
off
result is the hook's doing.
Background processes:
daemon, pty host and
bg-spare
must carry
--preload
in their environment (
/proc/<pid>/environ
on Linux); if not, restart the daemon.
Verify (after every update)
Preload loads:
BUN_OPTIONS="--preload $HOME/.local/share/no-agent-summary.js" CC_AGENT_SUMMARY_LOG=/tmp/nas.log claude --version && cat /tmp/nas.log
Expect
preload active mode=off …
. No line:
BUN_OPTIONS
did not reach the process, or the
path is not absolute.
Timer suppressed:
with the same
BUN_OPTIONS
and
CC_AGENT_SUMMARY_LOG=/tmp/nas.log
, run
a background subagent for a minute or two. The log shows
summary timer #1 suppressed (setTimeout, delay=30000)
and the agent's panel status stops
updating. If you export OpenTelemetry,
query_source = agent_summary
should stay at zero; this
is the only check that catches every failure mode.
Fail-open
Matching is by
source text
: an anchor must sit inside the callback passed to the timer. If an
update breaks that, the hook matches nothing and summaries silently come back. Ways it can happen:
the log line or query-source id is renamed;
the callback is passed via
fn.bind(...)
(no source in
toString
) or another wrapper;
the strings move to a shared constant outside the callback;
the timer moves to an unwrapped API (
timers/promises
, a scheduler loop).
So re-run Verify after every update.
Effect
We run it under every Claude Code process on our machine (2.1.301). Since then there have been
zero
agent_summary
requests, and no other side query grew to take its place.
Subagents, background agents, forked skills and background sessions run normally; only the
summary fork is skipped.
Visible change: the per-agent panel status stops updating; SDK
task_progress
has no
summary
.
Overhead: one
Function.prototype.toString
per distinct timer callback, cached in a
WeakMap
.
claude --version
: ~10 ms → ~17 ms (one measurement).

Why there is no setting for this
The documented switch only turns it on.
The SDK option
agentProgressSummaries
defaults to
false
, but in the bundle it is one term of an OR, and every code path that writes it sets
true
. So
false
changes nothing, and the undocumented
CLAUDE_CODE_AGENT_PROGRESS_SUMMARIES
can only enable summaries too.
The interval belongs to the server.
It comes from a per-model-family server flag and is
clamped to 30–240 s. The default is already the minimum, and no value disables the timer.
The obvious env vars miss.
DISABLE_NON_ESSENTIAL_MODEL_CALLS
, which some packagers set,
does not occur in the binary at all.
CLAUDE_CODE_FORK_SUBAGENT=0
and
CLAUDE_CODE_DISABLE_BACKGROUND_TASKS=1
do stop it, but only by taking fork subagents or
background agents with it.
The prompt cache makes it cheaper, not cheap.
About 98 % of these calls re-read the
transcript from cache; the ~2 % that hit a cold cache carry over a third of its cost.
Cost tools that read transcripts don't see it.
These requests are not written to the
session logs on disk (
#104358
); only
the OpenTelemetry export shows them. The docs section on background token usage doesn't list it
either, while Agent View's row summaries are documented as a Haiku-class model refreshing every
few minutes.
A cheaper variant already exists, switched off.
2.1.310 ships a
short
mode: about 2k
tokens of notes instead of the full transcript, optionally written by a smaller model. The
default is still the full transcript, and only server flags can change it.

Richest 0.1% (8M) produce more carbon pollution than 3.5B
Person in the richest 0.1 percent has contributed nearly 400 times more to extreme heatwaves than someone in the poorest half of humanity.
Oxfam’s research shows that while the super-rich are responsible for a disproportionate share of carbon pollution, it is ordinary people who bear the brunt of the resulting floods, fires and famine.
Oxfam’s new “Destroy & Rebuild Index” exposes how super-rich investors backing fossil fuels and other high-polluting industries are also profiting from disaster preparedness and clean-up.
Oxfam urges governments to make rich polluters pay and end climate profiteering.
The world’s richest 0.1 percent (8 million people) produces more carbon pollution than the world’s poorest 3.5 billion people combined, reveals new Oxfam analysis. Published ahead of the UN climate summit (COP31) in Türkiye, the report exposes how the world's super-rich are driving climate breakdown through their outsized emissions, while shielding themselves from the consequences and, increasingly, profiting from the destruction.
A person in the richest 0.1 percent has contributed nearly 400 times more to today’s extreme heatwaves than someone in the poorest 50 percent. Collectively, this small group of people produces over three times more carbon pollution than the entire population of Sub-Saharan Africa (1.3 billion people).
"The climate crisis is often described as a shared human challenge. It is not. Those who have done the least to cause it are losing their homes, their harvests and, increasingly, their lives. Meanwhile, the super-rich can buy their way out of danger – by retreating to high-tech underground survival bunkers, hiring private firefighting crews, and securing private insurance – and are actively profiting from the consequences of their pollution. This is not a tragedy of shared fate; it is a crime of extreme inequality,” said Oxfam International Executive Director Amitabh Behar.
Combining carbon inequality data with cutting-edge climate attribution models, Oxfam has found that:
The richest 1 percent are responsible for 20 percent of global warming since 1990 – 100 times more, per person, than someone in the poorest half of humanity.
Just one year of emissions by the richest 1 percent will cause 1.9 million excess heat-related deaths. 78 percent of these deaths will occur in low- and lower-middle-income countries, despite these countries being responsible for 8 percent of global emissions.
The emissions of the richest 1 percent will cause nearly $53 trillion in damage by 2050.
Used exclusively by the super-rich, private aviation remains one of the clearest examples of extreme carbon inequality. New analysis by Oxfam of private jet tracking data finds that:
Combined, private jets emit more carbon pollution in two seconds than someone in the poorest half of humanity emits in a year.
While the super-rich are responsible for a disproportionate share of carbon pollution, it is ordinary people who bear the brunt of the resulting floods, fires and famine. The super-rich buy safety through private insurance and homes in safer, cooler places. For everyone else, climate disasters mean destroyed homes and crops, depleted savings, and lost livelihoods. This leaves people even more exposed when the next disaster hits, deepening the inequality that made them far more vulnerable to climate disasters in the first place. By 2050, as many as 1 billion people (around 10 percent of the world’s population) could be displaced by the climate crisis. Most of those displaced will be in the Global South.
Oxfam’s report also shows how climate disasters have become an increasingly lucrative business. The global disaster recovery market is projected to grow from $70 billion to $92 billion annually by 2029.
Oxfam’s new Destroy & Rebuild Index identifies 217 corporations profiting from industries that fuel climate breakdown as well as disaster preparedness, recovery and reconstruction.
BlackRock and Vanguard are invested in 92 percent of the corporations in the index. Their combined investments total more than $1 trillion.
The report also warns that climate disasters are increasingly exploited to push policies that deepen inequality, including the privatization of climate action and public services, land grabs, deregulation and tax breaks benefiting the super-rich. The result is a vicious cycle of injustice: deaths from flooding are seven times higher in more unequal countries.
“The ultra-rich are setting the planet on fire and then charging the rest of us for the extinguishers," said Behar. "They profit from the pollution. They profit from the disaster. And they profit again from the clean-up.”
Oxfam is calling on governments meeting at COP31 to:
Make rich polluters pay to significantly and rapidly curb their carbon emissions, including through permanent wealth and income taxes, a permanent tax on fossil fuel corporations, and punitive taxes on high-emitting luxury items like private jets.
Substantially increase climate finance for the Global South, prioritizing public, grant-based finance rather than loans that deepen debt. The amount for adaptation should be tripled by 2035.
Radically reduce inequality within and between countries, including through climate-resilient public infrastructure and public services.
End profiteering from climate disasters. Governments need to curb corporate power in emergency response, reconstruction, and food systems during disasters.

Last year, the Redox team
received a grant
to develop io_uring-like Ring Buffer support at the system task level,
as a first step towards ring buffer communications between the application and the majority of system services.
This phase of the work finished up in September, as the last pieces were put in place.
The team has done a fantastic job, and I want to congratulate Ibuki, Anhad and Jacob, and thank them for their time and effort.
In addition to implementing the Ring Buffer machinery for our system services and drivers that can support it,
an
io_uring
and
liburing
-like API for applications was completed and demonstrated.
There was also substantial work done on support crates, including an async executor for drivers.
And there was some very exciting work on various performance improvements,
to allow much faster switching between applications and their system services.
But I will let the team tell you all the technical details.

Ring Buffers Overview
– Anhad Singh
Historically asynchronous I/O on Linux was done through the kernel’s native AIO interface. AIO is mainly useful for unbuffered (
O_DIRECT
)
file
I/O, and buffered requests silently block
1
. Developers also raised concerns about its complexity and performance
1
2
. There is also POSIX AIO, but developers often consider its implementation lackluster and slow
1
. To address these problems, several alternative asynchronous mechanisms such as
fibrils
and
syslets/threadlets
were proposed but were never merged into the mainline Linux kernel. In early 2019,
Jens Axboe
proposed and developed the io_uring interface, designed to be an efficient, extensible and “easy to use, hard to misuse.” In its early days, io_uring did have a few security issues and memory leaks, but these have since been addressed
3
. It was merged in Linux 5.1 and is widely used today.
The Linux io_uring interface allows the user to submit one or more I/O operations to the kernel, which are then processed in an asynchronous fashion without blocking the userspace process. Redox, being a microkernel, handles I/O in userspace
scheme
processes rather than in the kernel. Each
file description
stores a handle to its scheme, so an I/O system call on that file can forward the request to the scheme. The async I/O interface developed in this project, called Redox Rings, uses a mechanism similar to io_uring. However, unlike io_uring which is used to submit operations to the kernel, the Redox Rings interface is used by the application to directly submit requests to the appropriate scheme asynchronously without blocking the application. Additionally, the interface allows I/O requests to be issued without any memory copies, by having a separate shared memory region between the scheme and the application (which can be requested as DMA-capable memory).
For portability, the Redox Rings API is designed to be similar to that of
liburing
and can also be used for general inter-process communication. For example it is used for communication between the RedoxFS filesystem service and NVMed which is the storage driver. The addition of this API has allowed several parts of Redox to reap significant performance improvements!
Terminology
A ring buffer is a circular queue backed by an array. The interface makes use of two ring buffers which are shared between the application and the scheme:
SQ:
submission queue
, where the application writes requests and the scheme reads them
CQ:
completion queue
, where the scheme writes responses and the application reads them
SQE / CQE:
submission queue entry
/
completion queue entry
, entries in the SQ and CQ, respectively
Buffer pool: A contiguous block of memory, shared between the application and the scheme, from which data buffers are allocated
Data buffer: For a request, we currently support a single data buffer, which is a slice of the contiguous buffer pool, defined by an offset and length
Since each queue has exactly one producer and consumer, each index is only ever modified by one side. This eliminates the cost of having a shared locking mechanism.
The “redox-ring API”
– Ibuki Omatsu
We’ve introduced the first ring buffer implementation to Redox OS. Unlike Linux’s io_uring, the submission queue (SQ) and completion queue (CQ) are shared exclusively between userspace processes and are never accessed by the kernel.
redox-rings
is a new crate for ring buffer communication between userspace processes, also providing data structures for FFI use cases. It uses futexes as the main synchronization mechanism, with optional pipe file descriptor support.
Based on its FFI support, we’ve introduced the “redox-ring API” in relibc, inspired by Linux’s liburing.
liburing is a library for Linux’s io_uring, providing helpers for setting up and tearing down io_uring instances, as well as a simplified interface for submitting I/O requests.
Similarly, the redox-ring API allows applications to communicate with daemons that support ring buffers using custom protocols.
Key functions
The API provides functions for managing ring buffers, shared memory, and requests.
redox_ring_queue_init_with_path()
initializes a ring buffer connection to a daemon.
redox_ring_alloc_buf()
and
redox_ring_alloc_sized()
allocate buffers from the shared memory pool.
redox_ring_get_sqe()
obtains a submission queue entry (SQE) for preparing a request.
redox_ring_submit()
submits pending requests to the daemon.
redox_ring_wait_cqe()
waits for a completion queue entry (CQE), blocking if none is available.
redox_ring_cqe_seen()
marks a CQE as processed.
The API also provides functions for registering file descriptors, freeing allocated buffers, and tearing down ring buffer instances.
– Ibuki Omatsu
The
redox-rings
implementation uses shared memory to exchange SQEs, CQEs, and I/O data between applications and daemons.
During initialization, the SQ, CQ, and data buffer pool are mapped into the application’s address space using the
fmap
syscall with
MAP_SHARED
. This allows both sides to access the same memory without copying I/O data between processes.
Buffer allocation
The redox-ring API supports two buffer allocation strategies:
Fixed-size allocation: Uses a simple allocator that divides the shared memory pool into fixed-size chunks and maintains a list of available offsets.
Dynamic allocation: Uses the
redox-buffer-pool
crate to allocate buffers of varying sizes and alignments. The allocator uses B-trees to manage free and occupied memory regions.
Both allocation strategies return a pointer to the allocated buffer and its offset within the shared memory pool.
Once an operation has completed, the application can release its buffer, allowing the memory to be reused.
Session Creation and Management
– Anhad Singh
The
redox_ring_queue_init_with_path
function opens the scheme ring handle and uses the
SYS_CALL
system call on it to set up the ring buffer session with the given parameters. This returns file descriptors for the SQ, CQ, and shared buffer pool, which are mapped into the application’s address space. The application can then use the queues directly to submit requests and receive completions. On the scheme side, the worker task waits for entries in the SQ, processes them asynchronously and notifies the application on completion.
Example: Writing to RamFS
– Ibuki Omatsu
Ring buffer support was added to RamFS and NVMed. We also added tests that communicate with these storage daemons through the redox-ring API.
For example, writing data to RamFS involves the following steps:
Open the target file and initialize a ring buffer instance to RamFS using
redox_ring_queue_init_with_path()
.
Register the file descriptor so that subsequent requests can reference it by index.
Allocate a shared memory buffer and write the data into it.
Obtain an SQE and specify the write operation, file index, buffer offset, data length, and file offset.
Submit the prepared SQEs using
redox_ring_submit()
. Multiple requests can be submitted in a single batch.
Wait for CQEs, check the results, and release the buffers associated with completed requests.
Once all operations have completed, the application tears down the ring buffer connection.
Async Executor
– Anhad Singh
We developed an async executor for device drivers, with a single interrupt vector and an SQ/CQ pair per core architecture. A single core is used at the moment, and multi-thread-per-core support is in progress. Furthermore, we updated NVMe driver to use the async executor, and more devices such as virtio are expected to follow.
With the executor, schemes that support Redox Rings can handle each I/O request in its own async task, with a worker thread spawned for each session between the application and the scheme. On teardown, the worker task is stopped, pending I/O operations are cancelled and shared resources are cleaned up.
Figure 1:
Comparison between the
redox_syscall
and
redox_ring
benchmarks, showing that
redox_ring
is 14-15x faster. The
redox_syscall
benchmark performs I/O via synchronous system calls, while the
redox_ring
benchmark uses the new Redox Ring interface.
Kernel and IPC optimizations
– Jacob Lorentzon
While it has substantially improved over the years, IPC is still quite slow on Redox, and this is important to optimize as ring buffers can only offset this overhead to a certain extent. This has been a focus of our work to improve system performance.
Infrastructure
The
acid
test suite for Redox was expanded to include more targeted benchmarks that measure IPC latency, in particular
acid ipc_latency_simultaneous
, and also
acid heavy_forking
.
Support was also added for repeating measurements and collecting more proper statistics (although still less feature-complete than e.g.
hyperfine
), making it easier to know whether changes in metrics are statistically significant and by how much.
Miscellaneous refactors
Various single-digit speedups were attained from kernel refactors, such as eliminating redundant locking, hashmap lookups, and by adding a lower-overhead call for IPC, similar to seL4’s “reply-wait”.
Fast path switching without vector registers
Another source of overhead, from the flamegraphs, was found to be
XSAVE
and
XRSTOR
, a few hundred cycles combined (tested on an AMD Ryzen 9 5950X).
These instructions save/restore vector registers, which is ~600 bytes on the CPU tested, and likely similar on other CPUs with AVX2 (which only userspace uses).
The optimization made here is that the kernel zeroes the vector registers
if the caller and callee entered the kernel through syscalls
, rather than saving/restoring (using
vzeroall
,
ldmxcsr
etc. as required for correctness).
Context switching can be triggered both by preemption, i.e. timer interrupts, and voluntarily from syscalls.
After Redox destabilized its syscall ABI, instead preferring the
libredox
symbols provided by
relibc
, all syscalls will first go through a function call.
Since the System V ABI clobbers all vector registers
for all function calls
, it is almost zero-cost to also define Redox’s syscall ABI to do so.
Luckily, the generated assembly code for
relibc
was almost identical.
Direct switching
A major bottleneck during IPC is invoking the scheduler, as can be seen from various flamegraphs.
The scheduler needs to access multiple data structures, primarily
BTreeMap
that takes up a large fraction of the overhead, and it also needs to acquire lots of locks, often blocking.
Direct context switching was implemented in
kernel MR 694
, resulting in a 15-20% IPC latency reduction.
It separates the
current context
(reference) into the
scheduled context
and the
running context
, where the former is the context owning the current timeslice, and the latter is the context whose registers/memory/file table is currently active.
When direct switching has not occurred, these always coincide.
Consequently, a client process calling a scheme (typically using our
SYS_CALL
syscall) can completely bypass the scheduler and switch directly to the scheme, if ready, where the kernel will then prioritize returning to the
scheduled context
the next time the scheme yields.
This mimics the behavior of how complex syscalls are handled in monolithic kernels, and should also be more cache-efficient, among other efficiencies.
Huge pages
The kernel previously only supported 4k pages.
This is still the case on non-x86, and for all userspace cases, but now the kernel physmap will be mapped as 2M when possible.
TLB usage can thus theoretically be reduced by up to 512x for heavy CoW, and in practice, the highest obtained L1DTLB-miss rate from
acid heavy_forking
was -75%
.
Future improvements
– Jacob Lorentzon
IPC roundtrip latency has been reduced from ~5800 cycles to ~2700 cycles, but this is still high compared to fast µkernels like seL4.
Additional optimizations could be to reduce locking, and reduce the syscall entry overhead, but primarily to simplify the IPC primitive and remove possibly unnecessary parts such as request buffers.
While not as applicable for nonlegacy applications, automatic page-borrowing of clients’ buffers (in
UserScheme
) is also a major source of overhead and in a benchmark similar to
dd bs=4k if=/dev/zero of=/dev/null
, the overhead is at least ~32k cycles per call.
However, while the existing benchmarks are useful as an approximate lower bound on latency, more investigation will be required to determine the distribution of overheads for more realistic workloads, both with and without userspace ring buffers.
Electronic fibers weave touchscreen into sleeve that survives machine washing
the technology can display images and video, respond to finger presses, and connect wirelessly to digital devices, while retaining the breathability and flexibility of everyday fabric.
Researchers at the National University of Singapore (NUS) have developed a touchscreen integrated directly into a
garment
using electronic fibers that combine light-emitting diodes (LEDs) and touch sensors. Led by Assistant Professor Tural Khudiyev, the team integrates 54 of these fibers into a sleeve to create a flexible display that shows images and video, responds to finger presses, and connects wirelessly to digital devices. The research introduces a textile interface that retains the breathability and flexibility of everyday clothing while withstanding machine washing.
Unlike conventional wearable technology, which typically attaches a screen or electronic device to the body, the NUS team’s approach builds display and touch functionality into the fibers themselves. Each thread contains interconnected microelectronic components within a structure just one millimeter thick, allowing the fabric to function as an interactive screen without a rigid display panel. The prototype measures 168 by 105 millimeters, refreshes at 30 frames per second, and retains nearly unchanged display and touch performance after 50 machine-washing cycles. The technology could eventually allow clothing to function as an interface for digital information, environmental sensing, and health monitoring.

how to turn a thread into a screen
Conventional electronic circuits are designed on flat surfaces, where components can be arranged and connected across two dimensions. A thread, by contrast, is narrow and cylindrical, leaving little room for the complex wiring needed to operate a display. In order to overcome this limitation, the
researchers
developed an interconnection architecture that allows thousands of microelectronic devices to be connected along a single fiber. The process begins with tiny, insulated wires. A laser exposes specific points along their surfaces, while controlled wetting directs molten solder to the designated locations, creating electrical connections without joining unintended areas. Using this method, the team integrated more than 5,000 chips through over 20,000 electrical connections.
The interconnected digital LEDs are then incorporated into a multilayer fiber using a thermal drawing process. The resulting thread measures approximately one millimeter in diameter and 10 meters in length, with separate layers responsible for displaying images and detecting touch. A touch-sensitive layer sits beneath the LEDs. When someone presses the fiber, the contact completes an electrical circuit, allowing the system to identify the location of the touch and illuminate the nearest pixel. Display and interaction therefore happen within the same thread, rather than through separate components attached to the fabric.

a device that behaves like fabric
For the prototype, the team threaded 54 pixel-bearing fibers into the forearm of a sleeve. Each fiber carries 96 LEDs, combining to form a 96-by-54-pixel display measuring 168 by 105 millimeters. The screen refreshes at 30 frames per second and supports 8-bit color depth. The display is still modest in resolution compared with a smartphone, but its capabilities extend beyond showing static images. It can play video, display photographs, run a calculator, and function as a compass. Users can also receive images over Bluetooth, interact through voice commands, and rotate the display or adjust its brightness automatically. The sleeve incorporates additional fibers that carry a microphone, a speaker, and sensors for movement, temperature, magnetic orientation, and ambient light. A temperature-sensing fiber positioned under the arm, for example, can measure body temperature and display the reading on the sleeve itself. Each pixel fiber also has its own control channel, meaning a fault in one line does not necessarily interrupt the others. The system can register multiple touches simultaneously, bringing it closer to the interactive behavior of a conventional touchscreen.
According to the researchers, the prototype retained nearly unchanged light output and touch response after 50 machine-washing cycles with detergent and 1,000 bends around a radius of five millimeters. The integrated display is also reported to be as breathable as cotton, polyester, and denim, while remaining within established skin-contact safety limits.

toward clothing that senses and responds
Healthcare is one potential application identified by the team. Fibers equipped with physiological sensors could collect information continuously and present it directly on a garment, allowing wearers to access measurements without consulting a separate device. Combined with artificial intelligence, the researchers suggest, such systems could eventually support personalized monitoring and feedback. That possibility remains a future direction rather than a demonstrated capability of the current prototype. The team’s next steps include improving resolution, integrating more sensing functions, and exploring on-device AI. The broader implication is a shift in how digital interfaces are designed. Smartphones and computers have accustomed us to accessing information through dedicated screens, while wearable technology has largely miniaturized existing devices or attached them to the body. The NUS research proposes a different relationship between electronics and everyday objects, one in which information can be displayed on the material already in contact with the wearer.

We've open-sourced our
Accessible Components Library
, and, as you might expect, this includes the HTML, CSS, and JavaScript code. But, we thought, "Why stop there?" So, we've also published our documentation, including the accessibility requirements, test scenarios, and even the working automated tests which validate each one.
Here's what we've released, how it works, and why automated tests are worth the effort. One caveat: these components are opinionated and built for our needs. Feel free to reuse or adapt them, but test them in your product before relying on them. They're not a production-ready design system.
What we've released
As part of our efforts to provide useful
resources
to the accessibility community, we've released version 1.0.0, which includes eight components. We will be releasing more in the future, but for now you can check out:
Each component ships with working examples, the HTML, CSS, and JavaScript behind it, and documentation which explains:
What problem it solves
When to use it
When not to use it
Where to use it
Accessibility requirements
Test scenarios
Assistive technology compatibility
The accessibility requirements are the part which we think separates what we're doing from other component libraries. For every component, we've documented the applicable success criteria from the
Web Content Accessibility Guidelines (WCAG) 2.2
, at levels A, AA, and AAA. We've also added our own recommendations for things WCAG doesn't cover, such as usability when using high contrast themes.
Because WCAG can be challenging to navigate, we've grouped the requirements into ten themes, including:
Adaptability
Animation and movement
Assistive technologies and semantics
Colour and contrast
Consistency and predictability
Images and media
Input assistance
Keyboard
Navigation
Pointer and touch
This should make it easier to quickly understand how a component meets the needs of the people who use it.
Because there's always some technical jargon and caveats, we've also published our:
Glossary
, in case you come across some terms which are confusing
Documenting requirements is useful, but a document can't tell you whether a component actually meets them all. So, we converted each requirement into a test scenario using
Gherkin
syntax, and we wrote working
Cucumber
tests which validate them.
Gherkin is great because it describes complicated automated tests in plain language, using
Given
,
When
, and
Then
to describe each step. This makes it easier for non-developers to understand what the test is doing, and even help write tests. We've written about Gherkin before, and why it helps to
annotate designs using common language
.
Each of our Gherkin scenarios includes the following:
Tags
: used to run a subset of tests. For example, you might only want to run level A and AA tests, and ignore any recommendations
Rule
: the WCAG success criterion it relates to, or whether it's a recommendation
Scenario
: a description of what the test is checking for
Test steps
: the
Given
,
When
, and
Then
steps which describe exactly how it's tested
For example, here's our scenario for 1.4.10 Reflow on the
breadcrumbs
component:
@1.4.10@aa@automatic
Rule: 1.4.10 Reflow, Level AA
Scenario: Content reflows without horizontal scrolling at 320px wideGivenI load the sample "https://tetralogical.com/resources/accessible-components-library/breadcrumbs/examples/default.html"WhenI view the rendered '.tl-breadcrumbs'AndI set the viewport to 320px wide
Then it should reflow without requiring horizontal scrolling
This matters because you don't need to be able to read all the complex JavaScript code to understand what the test is doing. A designer, a tester, a product manager and a developer can all read the same scenario, and all agree on what it means to pass or fail. And, even if you don't use JavaScript on your project, because Cucumber is available in most mainstream programming languages, you can still use the Gherkin feature files and write your own tests to validate them.
All of our test scenarios are written from a collection of shared steps, which was a lot of work at the beginning, because we had to write the underlying code to validate each one. But, each step is reusable, so scaling is easy.
We've published a
full list of our test steps
which work out of the box. This list is generated from the actual step definitions we use in the repository, so it's kept in sync automatically. This means any time we add a new one, you'll also get it for free.
What the automated tests check
Behind each test step is JavaScript code that controls a real browser using
Playwright
. The tests load the sample from a URL, and then interact with it the same way a real person would, by clicking things or focusing them using a keyboard. Then, they pull information from the browser, like the states and properties of the elements, and verify whether the things that were supposed to happen actually happened.
This is where our tests go much further than off-the-shelf accessibility checkers. A lot of these tools are valuable, and we do recommend using them, but they mostly inspect static markup. They often tell you about things like a button having no accessible name, but they don't often tell you about more complicated scenarios, like whether a focus indicator is hidden behind another element.
Things which can't be automated
Most
of our tests are automated, which has taken a bit of creativity at times. But, not everything can be reliably automated, and we'd be a bit suspicious of any tool that claims it can be. For example, an automated test can easily confirm whether a form field has an associated label. However, it's a lot more difficult to assess whether the label actually makes sense to the person reading it, because that relies on context. Arguably, we could capture screenshots and code snippets, and throw them over a wall to a large language model to assess whether something is readable. But, we think that it's ok to have some things reviewed by a human, because it's
for
humans.
In version 1.0.0, 97% of our scenarios are fully automated. For the remaining 3%, rather than just skipping them, we've added functionality which gathers the information a reviewer needs from the browser, and creates a list of what needs to be checked manually. Every test run produces a JSON report of what passed and failed in the automated tests, plus a Markdown checklist of what still needs verifying by a human.
Finally, all the assistive technology testing on each component is manual. Even if a component passes all the automated and manual tests and is technically compliant, it doesn't guarantee that there won't be any quirks with a particular screen reader or browser. So, we manually check each component, and if something is broken, we fix it.
Why automated testing matters
In
our strategy work with large organisations
, we often find they struggle with
sustainable accessibility
. It's common for organisations to pay for an assessment, and then fix the issues. But, a few releases later, everything has quietly regressed, and nobody notices until a customer complains, or they pay for another accessibility assessment, which can get expensive.
Having automated tests breaks this cycle. You can plug them into your continuous integration (CI) pipeline, and have the tests run against every pull request, so you find out quickly when something is broken.
Here's why we think automated tests are so valuable:
Immediate feedback
: a developer can run all the tests on their own device in about 30 seconds, and know straight away if they've broken something
Regression protection
: every pull request runs all the tests as part of CI, so anybody reviewing your code can quickly check for regressions
Shared language
: the scenarios are written in plain English, so accessibility requirements stop being technical, and become acceptance criteria the whole team can read
Traceability
: Each scenario is tagged with a success criterion and conformance level, so it's easy to run a subset of tests, or search to see what's covered
Coding standards
: Linting rules and CI checks are built in, so regardless of who writes the code, it should always feel familiar
More time to spend on usability
: Because the mechanical checks are automated, people can spend more time on real-world testing, rather than inspecting the Document Object Model (DOM) for the hundredth time to see if a button is labelled
However, the cool part is that our website pulls all the documentation and tests directly from GitHub, so there's a single source of truth. The two can't drift apart or end up out of sync. So, if we want to add a new component to our website, we have to publish it to the repository first. This means you get it too, along with any tests and documentation that go with it.
We'll be releasing more components in the coming months. We've released a small set for now, so we can gather feedback and iron out any teething problems. So, make sure to star the repository to get any updates when they land.
Try it yourself
We've released the library under the
ISC licence
, so you're free to use, copy, modify, or share any of the code and documentation, as long as you don't remove the copyright notice.
If you want to run the tests, the
README
in the repository explains how to install and run the tests.
If you want to fork it and expand it yourself, the
development guide
explains how the repository is put together, and how you can add your own components and tests.
We're not accepting pull requests at the moment, as each component needs a full set of requirements, tests, and assistive technology checks, which we need to keep in sync with the code. And, because these are the components we use in our own work, we're keeping things opinionated and in-house, at least for now.

Dockworkers Worldwide Are About To Strike for Palestine
Published
The second International Day of Action of Dockworkers, in solidarity with Palestine and against militarism, begins this Friday — and could be the largest worker action against war in history.
In 1984, while the global struggle against apartheid burned hot, union dockworkers in San Francisco refused to unload South African cargo to demonstrate their hostility to a white supremacist, fascist regime. In so doing they reaffirmed what Harry Bridges, the first president of the International Longshore and Warehouse Union (ILWU), asserted when asked about what role organized workers should play in world affairs: “Interfere with the foreign policy of the country? Sure as hell! That’s our job, that’s our privilege, that’s our right, that’s our duty.”
Few workers believe that they have sufficient power to express political opinions at work, let alone insert themselves into global affairs by downing their tools. And yet, as revolutionary unionist “Big” Bill Haywood reminded, “If the workers are organized, all they have to do is to put their hands in their pockets and they have got the capitalist class whipped.”
Starting in 2023, the Palestinian General Federation of Trade Unions (PGFTU) called on workers and unions to “Stop Arming Israel.” In 2025, the
PGFTU
asked international workers to “organize days of rage and global solidarity in factories and workshops, in ports and airports, in the streets and public squares, in support of Palestine and its brave people.”
The Palestinian Boycott, Divestment, and Sanctions movement clearly builds upon the struggle against apartheid South Africa, arguably the most effective global social justice movement of the late twentieth century. As early as 1959, African National Congress President Chief Albert
Luthuli
, later awarded the Nobel Peace Prize, stated: “Economic boycott is one way in which the world at large can bring home to the South African authorities that they must either mend their ways or suffer for them.”
This Friday, October 30, dockworkers in around one hundred ports in nearly twenty countries will engage in perhaps the largest coordinated work stoppage in world history. The epicenter is the Mediterranean — where dockworkers in dozens of ports in Italy, Greece, France, Cyprus, the Basque Country, and Morocco — will refuse to work for either part of the day or the entire day. They will be joined by dockworkers and other workers who will rally in Spain, Turkey, Germany, Ireland, Portugal, Denmark, Sweden, Australia, Veracruz, Mexico, and Oakland, California as well as many ports in India.
They’re not demanding higher wages or shorter hours. In the words of two of the many posters circulating, “Dockworkers do not work for war” and “No Harbour for Genocide.” Dockworkers are saying they refuse to be complicit in waging war, let alone genocide.
The Ship Must Sail on Time
T
he history of strikes is inextricably linked to shipping. Tellingly, the English term for workers’ most powerful weapon, “strike,” has nautical origins. In their book
Many-Headed Hydra
, Peter Linebaugh and Marcus Rediker described how, in 1768, sailors in London “struck [took down] the sails of their vessels, crippling the commerce of the empire’s leading city and adding the strike to the armory of resistance.” Since then, the term for work stoppage has been
strike
. Shipping is central to capitalism: even today, upward of 90 percent of all goods consumed (either raw materials or finished products) are moved by ships.
For at least a century, dockworkers, seafarers, and other maritime workers have occasionally refused to load or unload cargo to protest imperialism, fascism, and war.
In 1935–36, dockworkers in the southern African ports of Durban, Cape Town, and Lüderitz Bay, as well as in San Francisco, refused to load cargo aboard Italian ships to protest that fascist empire’s invasion of Ethiopia.
In the late 1930s, dockworkers in Local 10, the ILWU’s San Francisco Bay Area branch, partnered with the Chinese community to refuse to load cargo for imperial Japan to protest its invasion of China.
The most widespread example of global dockworker activism was against apartheid South Africa. In San Francisco, Brooklyn, Sydney, Port of Spain (Trinidad), Gothenburg (Sweden), Copenhagen, and many other ports, union workers refused to handle cargo.
Anti-apartheid activism among workers was not limited to shipping. Irish supermarket workers led a multiyear campaign by refusing to check out customers who bought South African products, as dramatically described by Irish author
Sally Rooney
.
Perhaps the most relevant example was ILWU Local 10’s
campaign
against fascist Chile. In 1978, San Francisco dockworkers and clerks of ILWU Local 34 discovered the US military was secretly shipping weapons to Chile. The ILWU had staunchly supported the previous regime, led by socialist Salvador Allende, overthrown in 1973 in a military coup led by Augusto Pinochet, with the active support of the United States.
Local 10 activists including Herb Mills, who later wrote a fictionalized account called
Presente
, partnered with Chilean exiles, Bay Area Latinos, the Catholic Church, and others to press the US government to stop any sending of military supplies. In tandem with sympathetic congressional members, the ILWU helped convince the Carter administration to reverse US policy and stop sending military equipment to Chile.
Dockworker Solidarity With Palestine
T
he PGFTU’s 2025 “Cry Before Death” stated: “Our union comrades, we await your role in delivering the cry of the children and workers of Gaza to decision-makers and to the streets.”
In solidarity with the Palestinian labor movement, the second International Day of Action of Dockworkers seeks to disrupt the global supply chain first and foremost in Mediterranean ports, which is the “front line” in the struggle against Israel’s war on Palestine — as well as its wars on Lebanon, Turkey, Syria, and Iran — all supplied by US and European military equipment and ammunition.
Since 2019, when they refused to load weapons for Saudi Arabia’s war in Yemen, dockworkers in Genoa — Italy’s busiest port — have emerged as a leading force. Last year, in solidarity with the Global Sumud Flotilla that sought to break Israel’s illegal blockade of Gaza, one Genovese dockworker promised, “If we lose contact with our boats, with our comrades, even for just twenty minutes, we will block all of Europe.” Last fall, among the flotilla participants was the Genovese docker activist José Nivoi and the Amazon union activist Chris Smalls.
The Genovese dockers have strong support from a well-organized civil society, student groups, and supportive local government. This fall, Genoa also is hosting a sound installation by artist Hajra Waheed,
Hum III
:
From Port to Port, A Sonic Convening
. Waheed’s exhibition explores the historical tradition of radical labor organizing, antifascism, and internationalism in Casablanca, Chattogram, Durban, Genoa, Sydney, Jaffa, and other ports. Waheed intentionally connects histories of direct action to dockworkers engaged in opposing apartheid Israel, including on October 30.
The World Federation of Trade Unions (
WFTU
), an Athens-based organization with affiliated unions representing 105 million workers, is
cosponsoring
this action:
The mobilization is taking place at a critical time, as military conflicts are spreading and war fronts are dangerously expanding and becoming interconnected, from Ukraine to the Middle East. The murderous state of Israel, with the support of the USA, the European Union and NATO, continues its crime against the Palestinian people and escalates its military aggression against Iran and Lebanon, increasing the danger of an even broader conflict.
The WFTU highlights that workers “in the metal industry and shipyards, railways, energy, telecommunications, transport and logistics. . . . ports, industrial zones and military infrastructure. . . . [also] can play a decisive role in the common struggle against imperialist war and exploitation.”
Charmaine Chua, a scholar of supply chain disruptions and an organizer with Workers in Palestine, provides more specifics about
strategic nodes sustaining Israel’s genocide: from Turkey supplying crude oil through the port of Ceyhan, to coal exports from South Africa, to shipments of components to Elbit Systems from Genoa, Ravenna, Livorno, and more, to Oakland’s role in supplying US military operations across the world. To trace the role of these ports in genocide is to see the tentacles of fuel, weapons systems, and renewable energy feeding the Israeli and US war machines. But if ports have become an astonishing crystallization of our states’ callous complicity in the war machine, the immense solidarity of dockworkers and civil society reveals the mass opposition forming in response to these ongoing catastrophes.
One must also understand that, since the supply chain — which makes “modern” war possible — is global, shutting down one port, or even the ports in one country, is insufficient. That is why Katy Fox-Hodess wrote that no strategic choke point is a “magic bullet” and why she, along with coauthor Rafeef Ziadah, began studying “
Labour Internationalism in a Time of Genocide
.”
Chua goes further: “Meaningful labor solidarity with Palestine will require all of us to find where we have other points of leverage in our own workplaces, to sustain organizing on our own shop floors, and to build a unionism committed to organizing everywhere, rather than only at strategic sites.”
While dockworkers soon will take the stage, some could not wait. Last week in Livorno, dockworkers disrupted the movement of US military cargo from the joint Italian Air Base and
US Naval Air Station Sigonella
, nicknamed the “Hub of the Med.”
This Friday, dockworkers across much of the Mediterranean and beyond will stop work and rally against war and genocide. In today’s world, workers seeking to shape global politics must organize across industries and nations. While this Friday’s action should be huge, how workers respond next week and those to come will be even more important.

In general, LLM performance is incredibly multidimensional. There's no guarantee of a fixed ordering where the model that is best at math is also the model that's best at jokes. Despite that complexity, much of the variation in performance is explained by just a single variable: model size. In general, models that are bigger will (a) be more performant / reliable, (b) cost more per token, and (c) have better recall of esoteric facts. As you note, our models are ordered:
Luna < Terra < Sol < Astra
[
...
] These days, version number signifies a few things at once: the order of release, the relationship to other releases, and the magnitude of improvement. So something like 6.1 would indicate it was launched after 5.6, may share some similarities to other 6.1 models in terms of training data / personality (which is why it's not 5.7), and isn't a giant enough leap to merit the headlines and expectations that would come with a 7.

New York City's renewable energy buildout continues at a snail's pace. As of 2025, 90 percent of the power we use in the city comes
from non-renewable power sources like fossil fuels
burned at local power plants, while peaker plants burning fossil fuels continue to line the city's waterfront, spewing nitrogen oxide and other particulates into the city's neighborhoods during the hottest days of summer. The City has set a goal of relying on 100 percent renewable energy by 2040, but that looks increasingly unlikely, even with the long-awaited Champlain Hudson Power Express line bringing hydroelectricity in from Québec. New York's massive wind power projects are in the crosshairs of the Trump administration, and Governor Kathy Hochul has embraced an "all-of-the-above approach" to energy: approving a fossil fuel pipeline and pursuing a dramatic—and controversial—
expansion
of nuclear capacity in the state.
But there has been one bright spot amidst all the climate and energy backsliding—New York City has been building out its solar power infrastructure far faster than expected, with the city expected to smash a 2030 goal for 100 megawatts of solar four years early. Solar power, unlike wind turbines, nuclear energy, or hydroelectricity, is cheap to build, and is done with no collateral consequences for nearby communities.
A stock Qwen 3.5 4B with a RISC-V CPU compiled into its weights, running on its own Gated DeltaNet layers as RAM.
I can't believe it's not silicon
Qwenputer is a pretty fun experimental model. It's a stock Qwen 3.5 4B with one addition: a RISC-V CPU embedded within the weights that uses the model's own Gated DeltaNet attention layers as RAM. (To learn how GDN works,
here's a handy guide
.) This 'CPU' runs completely within the forward passes of the model, and can run arithmetic operations, C and MicroPython code without any external runtime or tool usage whatsoever.
To be very clear, it is not a plugin, a tool or a sandbox. This blog will explain exactly how this model works, and how the model utilises GDN layers as RAM, and how I also slotted in an experimental in-model file storage.
Qwen3-Next and Qwen 3.5 (the model Qwenputer is built on) use a pretty neat trick. 3 out of 4 attention layers in the model use Gated DeltaNet, a linear RNN, as the attention mechanism (
more on that here
). Each head keeps a state matrix, and the delta rule keeps this updated.
Now, here's where our fun experiment starts. I found out that by setting the gate to 1,
1
1
Each Gated DeltaNet head keeps a state matrix, its memory. At every token, before writing anything new, it multiplies the whole state by the gate, a number between 0 and 1. That's how the RNN forgets: a gate of 0.9 fades everything stored a little on every token, and a gate of 1 means nothing ever fades.
the write strength (beta) to 1,
2
2
After the gate, the head nudges one direction of the state towards a new value, and the write strength beta sets how far. A beta of 1 means the old value along that direction is replaced completely instead of blended.
and using one-hot key encoding,
3
3
A one-hot key is a vector of zeros with a single 1 in it, so it points at exactly one row of the state, the way a memory address points at one cell.
every write we perform will overwrite exactly one row, and every one-hot query can retrieve an exact value. This means that the GDN layers themselves can work exactly as RAM, at a far lower cost than using normal attention as RAM, since a GDN head's state stays the same size however long the conversation gets, unlike attention's KV cache.
Gated DeltaNet state used as RAM: a one-hot key overwrites one row, a one-hot query reads it back, and the CPU keeps its registers, memory and program counter in those rows
The idea that the delta rule acts as a memory isn't new: Schlag et al. (2021) showed that linear attention with the delta rule works as an associative memory, or "fast weights".

Imanol Schlag, Kazuki Irie and Jürgen Schmidhuber, "
Linear Transformers Are Secretly Fast Weight Programmers
", ICML 2021.
The new thing here is making it exact and addressable, inside a production model, reliably enough to run a whole CPU on it.
This is the base on which this entire model is built. As it stands, default Qwen 3.5 does not keep exact values in the GDN. With this modification, we unlock the next part of this experiment.
Compiling a computer into layers
Since we have a fully functional, cheap and fast RAM now, we can go ahead with compiling a working CPU into the model weights. Luckily, there's no training involved: a compiler sets every weight directly. You describe the CPU as a circuit, a long list of small steps like "read this register", "add these two numbers" or "jump if zero", and the compiler turns each step into a piece of a transformer layer: attention heads that look things up, feed-forward units that do the arithmetic, and DeltaNet heads that hold the RAM. The CPU then runs as the model decodes.
Each instruction becomes a few generated tokens: one names the memory row to write (ADDR), the next carries the value (VAL), and a STEP token ends the instruction. Those tokens are the CPU's execution trace, so while Qwen is generating them, the CPU is actually running.
The CPU
The CPU is a 32-bit RISC-V core (RV32IM, plus the Zba extension and a small bignum unit for big-number arithmetic), and it takes up 11 layers in front of Qwen's 32. As it stands, it passes the official riscv-tests, its programs match qemu, and it has run 18 million instructions free-running without a single error.
5
5
Free-running means the CPU keeps going on its own outputs for the whole run, with no reference machine correcting it between steps.
This CPU can also run C and MicroPython code in the forward passes quite well (although a bit slowly). It is not a Linux-class chip yet, but it implements the full RV32IM instruction set.
How Qwen uses it
Qwen 3.5 4B is able to use this CPU quite well, without any post-training required. The CPU is used completely internally, and not invoked through any external tool calls.
In order to make the model use this reliably, I decided to go the cheap way: by piggybacking on the tool call format that models are quite well-trained on, Qwen sends the CPU its instructions and reads back the results.
No external tool calls or runtime are used.
Once our CPU receives the instructions, the computer layers run, and then write the tool response. We use a small driver called RvChat to load the firmware into the GDN state, and this keeps the trace tokens out of Qwen's layers.
Qwen's original weights stay exactly as they are. The computer weights are added on top of them, in extra dims and layers.
Does it work?
I think the main question here on your mind after reading through my incessant ranting will be: does this actually work?
Accuracy of base Qwen3.5-4B, Qwenputer and base Qwen with a Python tool on NUPA and DeepMind arithmetic sets
On the DeepMind sets:
div_big: Qwenputer scores 97.5%, versus 95% by giving Qwen 3.5 4B a Python tool and 72.5% for base Qwen.
mul_big: Qwenputer scores 97.5%, versus 100% with a Python tool and 55% for base Qwen.
mul_div_multiple_longer: Qwenputer scores 100%, versus 97.5% with a Python tool and 90% for base Qwen.
add_or_sub_big: Qwenputer scores 97.5%, the same as with a Python tool, and 87.5% for base Qwen.
On NUPA's long-integer arithmetic, Qwenputer goes from 48.6% to 100%, the same as giving Qwen a Python tool.
The numbers the CPU prints are exact, too: I replayed about 230,000 of its output positions against a reference machine and found zero mismatches. And bolting a computer onto Qwen doesn't change how it talks: its normal text stays within noise of base Qwen (KL 6e-4, against a noise floor of 5e-4).
A hard drive? In this economy?
Because a CPU inside a language model clearly wasn't cursed enough, I decided the prudent thing would be to give it a filesystem too.
Since we already have a functional RAM, this was mostly trivial. On the model side, it's exposed via internal put / append / get / list / delete operations.
Once again, no actual tool calls.
When Qwen 'saves' a file, the compiled layers hash its name into one of 1,024 slots in a directory kept in the DeltaNet state, and store the text itself in other heads, with eight tokens per row, chained together. In scenarios where two names end up landing on the same slot, it just checks the next one. Finding a file again takes roughly two or three steps instead of a scan, and it holds up to 512 files, which comes out to about 53,000 tokens of text.
Fun thing is, this is quite persistent. You can save the state at the end of a conversation, load it into the next one, and the files are still there. Using this filesystem, Qwen gets facts that changed between chats right 90% of the time, against 30% when you paste the old chats back in, and it's on par with giving Qwen memory tools run by Python (83.3% vs 78.9%). This one is still experimental, and its code lives on the
rv-store branch
, with the model on
Hugging Face
and
ModelScope
.
Limits and what's next
Qwenputer is very much an experiment, so a few limitations. The extra layers and wider hidden size make the checkpoint 18.8 GB, roughly double base Qwen, although most of it is zero padding. It also needs a small driver (RvChat) to boot the firmware and keep the trace tokens out of Qwen's layers, so it doesn't run with a plain
generate()
call yet. And it's a bit slow, with every CPU instruction costing a few decoded tokens, so a big calculation takes seconds rather than milliseconds. The batched executor I used for the benchmarks runs about 3,200 CPU tokens a second on an L4.
Next up, I want Qwen to write Python and run it on the MicroPython inside its own weights, through a
python()
tool that works the same way
calc
does. Making the CPU faster is the other big one.
If you want to play with it yourself, the model runs on a single 24 GB GPU. You'll need
uv
and the Hugging Face CLI. You
don't
need a tool server or a Python sandbox for the calculations: the CPU runs them inside the model.

On October 20 and 21, an attacker tried to exploit a GitLab vulnerability (CVE-2026-97229) on our instance, a week after the fix was released. The attack came close to working. We have found no evidence that it succeeded, but we cannot rule it out, so we treated the instance as compromised and rebuilt it from scratch. Our checks show that the aports repository, packages, and the October 21 releases were not tampered with.
GitLab is being tested before we open it to the public again. All passwords have been reset, so when it is back you will need to set a new one with “Forgot your password?” on the sign-in page. We will post exactly what you need to do when it reopens. In the meantime: if you used the same password for your gitlab.alpinelinux.org account anywhere else, change it there. We have seen automated login attempts against our GitLab with passwords leaked from other sites.
If you have questions or concerns please reach out to us at infra@alpinelinux.org.
What happened
The vulnerability:
CVE-2026-97229 is a critical (CVSS 10.0) vulnerability in how GitLab evaluates regular expressions in CI configuration. The underlying bug is in Onigmo, the regular expression engine built into Ruby.
GitLab published fixed releases on October 12
, but the fix itself is a set of patches to the Ruby that GitLab bundles in its own packages and container images. Upstream Ruby
shipped the fix on October 23
, in Ruby 3.3.13, 3.4.12 and 4.0.9.
The attack:
On October 20 and 21, a newly registered account sent crafted CI configurations to our GitLab instance, which was still running 19.3.4 and did not have the October 12 fix. This crashed GitLab worker processes 8 times. In 4 of those crashes the attacker got partway through the exploit and failed at the next step. The attacker also downloaded our GitLab container image, which suggests they were tuning the exploit to our exact build. We have found no evidence that the attacker ran code on the server, but we cannot rule it out.
Our upgrade didn’t fix the vulnerability:
Upgrading to GitLab 19.3.6 on October 22 didn’t fix the vulnerability. The fix isn’t in GitLab’s own code but in a patch to Ruby, which GitLab applies only in its official packages. Our image used standard Ruby, so it didn’t get the patch.
If you run GitLab with your own Ruby (from source or in your own container image) rather than GitLab’s packages, upgrading GitLab is not enough: you also need Ruby 3.3.13, 3.4.12, 4.0.9 or later.
If you use our
alpinelinux/gitlab
container image, pull
alpinelinux/gitlab:19.3.6
again. The image published on October 27 contains Ruby 3.3.13. Any 19.3.6 image you pulled before October 27, and all older tags, are vulnerable.

What we know and what we can’t rule out
What we found
Alpine releases and packages were not modified.
The October 21 stable releases (3.21.9, 3.22.7, 3.23.7, 3.24.3), including their ISO images and the minirootfs tarballs the official
alpine
Docker images are built from, and all packages built from October 20 to 24 came from aports commits we verified against records outside GitLab. See the FAQ below for details.
No signing keys were exposed.
The keys that sign Alpine packages and releases are not, and never have been, stored on the GitLab server.
No evidence that the attacker’s code ran: timing probes showed no delays, and we found no unexpected files, keys, hooks or processes.
No private data was returned to the attacker through any web or API request we can see.
Why we can’t be sure
A successful exploit would leave no crash and no trace in the web logs.
Some logs from the attack day are gone (background job logs, the old container’s filesystem).
We had no logging of outbound network connections, and our hosting provider keeps none either.
What could have been exposed if the attack succeeded
Email addresses, names and IP addresses of all users
Password hashes
2FA secrets, CI/CD variables and runner tokens
Webhook, integration and push mirror credentials
Personal access tokens (stored as hashes)
Private repositories, and confidential issues and merge requests
FAQ
Why did we rebuild GitLab if we were able to mitigate the attack?
Because we cannot rule out code execution, and the evidence we would need to confirm it no longer exists, we took the harder route and rebuilt the GitLab instance from scratch. This removes any foothold a possibly successful exploit could have left behind.
While GitLab is closed, our package mirrors, cgit, and mailing lists/IRC are available as normal.
Are Alpine packages and releases affected?
We have found no sign of tampering in aports or the releases.
Every aports commit added October 20 to 22 arrived through a recorded push by a known developer. We checked this against records the attacker could not reach: a developer’s clone and all 45 builders. Every package built from October 20 to 24, on every architecture, came from commits as published on git.alpinelinux.org. The October 21 releases (3.21.9, 3.22.7, 3.23.7, 3.24.3) were built from those same verified commits.
We ran these checks on October 24, covering commits from October 20 to 22 and packages built up to October 24. Our GitLab stayed vulnerable until we closed it on October 27, so we are extending the same checks to that date.
Is Alpine’s ruby package affected?
The bug is in Ruby’s regular expression engine, so any program that compiles regular expressions from untrusted input is exposed, not only GitLab. Alpine 3.22, 3.23, 3.24 and edge ship Ruby 3.4.12, and Alpine 3.21 ships Ruby 3.3.13; both include the fix. Run
apk upgrade
to get it.
What are we changing in response to this event?
Fixed Ruby:
the rebuilt instance runs a Ruby with the fix (3.3.13 or later).
Faster patching:
apply critical GitLab security releases within a day, and check each release for Ruby or other component patches our own build must apply.
Better logging:
record outbound connections from the GitLab host and database connections, and keep logs longer than 14 days.
Signed release tags
, so releases can be verified independently of GitLab.

AURA’s glasses are also under 95 grams, because the heavy processing happens in a portable compute puck, connected by a cable. It holds the battery and the new Snapdragon® Reality Elite platform from Qualcomm Technologies, Inc., which debuts on AURA, so you get the best of both worlds: high-performance spatial computing and lightweight comfort.
Android XR brings the helpfulness of Gemini and millions of your favorite apps from Google Play, including over 150 apps made for XR, to AURA. So wherever you are, you can work, watch, and play with Gemini by your side on AURA’s unbounded canvas.
A workspace that travels with you
On AURA, you can open up multiple apps at once, like your browser, work documents and your music app, and arrange them around you at any size. Pair a Bluetooth keyboard and mouse, or use the puck as a trackpad, for a complete desktop setup anywhere whether you want a massive, multi-monitor display from your couch, at a hotel desk, or on an airplane tray table.
With Wired Mirroring, your laptop can join in, too. Plug it into AURA with a USB-C cable that supports video output, and its screen appears as a window you can resize and place anywhere. There’s no software to install and you can use it side-by-side with your Android XR apps on AURA. And because the display is visible only to you, you can open a confidential document in a public space with peace of mind.
Plug in your laptop with Wired Mirroring and spread your work across multiple windows.
Gemini works across everything in view, including your laptop window, so you can ask it to tidy up your windows or brainstorm about whatever you're looking at. And starting today, it can do more than talk you through an answer: Share your view, and Gemini can highlight what to focus on, in the room around you or on your screen.
Ask Gemini about anything in front of you, like finding places to visit while in Google Maps.
A private theater for your shows and memories
When it's time to unwind, AURA turns any seat into the best one in the house. Open YouTube, Google TV, or your favorite streaming service and place the screen wherever it's most comfortable. You can dim the lenses to fade out the world around you, and they instantly become transparent again when someone is in view.
There's already plenty of immersive content to watch on YouTube and Google TV, from 180- and 360-degree videos to 3D movies. New immersive films and performances made for XR also arrive with AURA today, including “Nevatars”, co-directed by Andy Serkis and Josh Nelson Youssef, “Galapagos: the Last Eden,” narrated by Margot Robbie, from Atlantic Studios, and the San Francisco Ballet's “Nutcracker.”
For even more, spatial view turns almost any video, photo, or game into 3D with a tap, now supporting higher-resolution content. And with window follow mode, your app will stay centered in front of you allowing you to enjoy your content in any position. It also tucks into a mini view at the edge of your vision when you are on the move, so your path stays clear.
Your memories are back in focus too. This year, Google Photos will include a new spatial gallery that wraps your library around you. You can pan from an entire year down to a single day with your hands, then open a favorite memory in 3D.
An arcade wherever you are
Whether it's getting through a few levels at the airport gate or a long session on the couch, AURA gives your games a bigger screen. Since it's Android, you can play thousands of mobile and tablet games from Google Play or bring in games from your handheld or PC with Wired Mirroring. You can also keep other apps open beside the game, like a YouTube walkthrough or a chat with friends. And if you get stuck while playing an Android title or streaming from your PC or console, just ask Gemini to talk you through your next move, so you don't have to put down your controller.
Play your favorites on a bigger screen, or try new games made for XR.
Games made for XR, from studios like Owlchemy Labs, and Resolution Games, also appear right in your space, and you can play them naturally with your hands. New ones are coming with AURA, too, including Fallout Factions and Project Hail Mary: Journey Among the Stars.

Claude Code found 145,763 photos I permanently deleted from my iPhone.
Three years of deleted photos and videos still sitting in a hidden cache. Any app with file access can read them.
I plugged my iPhone into my MacBook to run a backup. Claude Code was doing the security audit from my last post and flagged a directory I wasn't even looking for.
PhotoData/Thumbnails. Over 146,000 files. Photos, videos, screenshots. Every single one was something I deleted.
Photos from 2023, 2024 and 2025. The ones I deleted the second after taking them. The ones I cleared from Recently Deleted. The ones I deleted three separate times because I wanted to be sure they were gone. All still there.
Passport photo I took for a visa application in 2023.
Screenshots of my bank app with full account numbers visible.
Private photos I sent someone and immediately deleted after a breakup.
Screenshot of my crypto seed phrase I took temporarily in 2022.
Photo of my ID and credit card I took to remember the numbers and deleted 5 seconds later.
Screenshots of my ex's private Instagram stories I saved and permanently deleted in 2023.
Some were full resolution. All organized by date going back to 2021.
When you delete a photo on iPhone, iOS removes it from your camera roll and Recently Deleted. It keeps a compressed copy in a Spotlight search index cache so your phone can find things when you search. Apple never clears it. Not after 30 days. Not after a year. Never.
They told you it was permanently deleted. It wasn't.
I checked which apps on my phone had Files and Folders access. 23 apps. Weather apps. QR code scanners. PDF readers. A flashlight app I downloaded in 2022. Any one of them could have been reading every photo I ever deleted this entire time.
Went from 23 apps to 3 in about two minutes.
Full step by step below. Takes 2 minutes. Save it so you don't lose it and send it to anyone with an iPhone.
I’m writing this post from a hospital bed. And I couldn’t be happier.
You hear folks say chemotherapy sucks, but until you go through it yourself, you don’t really know how bad it can be. It remains a popular activity only because it’s better than
the alternative.
My first exposure to chemotherapy was with this contraption: a fluoroscope.
Lovely to look at, less lovely to lie on.
Every week, they used this machine to tap into my spine, extract 5 mg of fluid for analysis, and replace it with 5 mg of
methotrexate
. There was only a local anesthetic during the procedure and the hardest part was knowing that there was a needle, turned up to eleven, going into my back.
It was afterwards that things got dicey: the nerves in your spine float in a
thecal sac
filled with spinal fluid that acts as a kind of insulator. Since we were exchanging the fluids, it was easy for the levels to get out of balance and for the nerves to react.
The result were the worst headaches I’ve ever experienced. The good news is that the remedy was simple: to lie flat on my back to ease the pressure gravity was putting on my spine.
That was also the bad news: many days were spent lying prone and trying to avoid boredom. Watching shows and scrolling timelines just doesn’t cut it when that’s all you can do.
Thankfully, the spinal headaches subsided quickly when the six-week course of lumbar punctures finished at the end of January. But my body began to face a new challenge: chemotherapy infusions of
Bendamustine
and
Rituximab
.
Everyone experiences chemotherapy differently. Just as every body is different, so is the reaction to the chemicals that are killing the cancer.
The first effect I noticed was in my tastebuds: everything I put in my mouth had a slightly metalic taste, so my eating habits changed. My beloved morning coffee was replaced by tea, food needed a lot less salt, and I started eating a blander diet (cottage cheese with berries remains a favorite).
Some people experience nausea and other gastric issues: luckily, I avoided that. I also didn’t have any hair loss, but my normally thick and curly hair lost its body and became lifeless: an external expression of what was happening to me internally.
As someone who’s always been active and strong, the biggest overall effect of chemo was losing muscle mass and suffering from overall fatigue. It felt very strange to be weak.
I was on a 28 day cycle for my infusions: during the first week I got pumped full of chemicals and then spent three weeks letting my body process them. One of the things they gave me with the infusion on a Tuesday was a dose of steroids that gives the body a boost during the initial onslaught. But by the weekend, that wore off and I felt like shit. It usually took until the middle of the second week before I started feeling human again.
I didn’t lose my appetite, but I wasn’t eating more than normal. The problem was my metabolism was working overtime and my calorie intake didn’t adjust. I lost 50 pounds over the course of a couple of months and eventually got to the point where I was having five meals a day. Too bad it all tasted bad.
This could also be a graph of my happiness.
One thing that I did to fight my diminished capacity was a daily walk. Anyone who exercises regularly knows that there are always plenty of reasons to avoid it: you didn’t sleep well, you have an important project to finish, or you’re sore from a previous workout. When you’re doing chemo, add feeling like absolute shit to that list.
I still had nerve damage in my spine, so my “walk” was more like a shuffle. Thankfully my wife found some awesome
walking sticks
to aid with my balance. They are clearly labelled “Not A Medical Device” but they are my most important medical device.
Winter sunsets, exercise, and walking sticks are good medicine.
My daily exercise was just like any gym workout: dread at the start, joy at the end. Sometimes there wasn’t much behind that joy: at my lowest point, a walk around the block on flat ground got my heart rate up to 160 bpm. Breathtaking, literally.
That low point was in March. In the week following my infusion, where I was already feeling like crap, I came down with a type of
pneumonia
that affects people with weakened immune systems. I had no strength and my blood oxygen level plummeted below 90%. Getting from the living room to the kitchen for a drink of water felt like running a marathon, and then my Apple Watch pinged to inform me that I was having an episode of atrial fibrillation. It was
a lot
and I honestly had thoughts of “is this how it ends?”
Thankfully, antibiotics battled the pneumonia quickly and the chemo effects subsided. My doctor offered to skip the next cycle of chemotherapy, but I decided to push on. There is only one way to be done with a thing.
Throughout all of the infusions, the nerve damage that occurred before the lymphoma discovery didn’t improve. As I said above, my gait and balance were severely compromised: going up and down stairs was particularly challenging. The tingling sensations on my backside and numbness near my abdomen became a bigger concern with each passing month. It wasn’t getting better and I feared it was a permanent condition.
I finished the last of my infusions in May and my body slowly started to recover. Food started tasting better, and my strength and stamina started to return. My daily walks got longer: first a quarter of a mile, then half a mile, then a mile, and then something fantastic happened.
At the end of a walk around our
local state park
, I went to grab something in the car glovebox. As I did this, I tilted my head forward and the back of my legs lit up with a feeling I had never felt. Something was changing in my spine: and after a couple of weeks it was clear that this was a sign that the nerves were fixing themselves.
Our guess is that the chemotherapy infusions, which attack white blood cells and other parts of the blood that aid in recovery, had retarded the healing in my nervous system. Now that my body had a chance to repair itself, it was.
I can now go up and down stairs without hanging on for dear life. I’m able to walk without aid, but I still like my walking sticks for longer outings since they let me push myself harder. I’ve also started working out in a gym with a trainer: I told him about my stair issues, and now he has me doing them backwards and by hopping on all fours. I am so happy to look like a doofus, and for the continued improvement I’m seeing with exercise.
My regained ability to walk and a stronger immune system allowed me to leave the house. My first night away from home was a short trip to Topanga Canyon to celebrate an August birthday:
All hail the sunflower goddess!
After that successful trip, we took a short boat ride to have a nice lunch and
look at some kelp
. It felt so good to be able to do normal things again.
A trip to visit The Blue Forest
One lingering part of my life that hasn’t been reestablished is swimming. All the chemotherapy that has been put into my body has been through a
port catheter
: a small device under my skin that hooks directly into my carotid artery. Getting an infection there would be a very bad thing, and water increases that risk: be it from ocean water full of living organisms or a swimming pool that kids pee in.
With the current El Niño conditions, that’s been a hard thing: the water is warm and “interesting”. My new gym also has a beautiful Olympic-sized pool for lap swimming. I’m happy to be in this hospital bed doing a final stint of chemotherapy because when I’m done, the port is removed.
This last procedure is to make sure there is no lymphoma in my brain fluids: not a difficult or dangerous treatment and the side effects are minimal. But it does require close monitoring because of the high dosages involved.
In six weeks, I’ll be done and spend the winter in that heated pool so that I can finally swim in my beloved Pacific next summer. The buoys are still there, even though the high surf this summer knocked one out!
Last year was hard, and it got worse over time. This year has also been hard, but it’s gotten better with each passing month. For that I’m grateful.
I’m also grateful for my wife Lauren: it’s impossible to imagine making it through all of this without her help, support, and encouragement. The silver lining in all this strife is that it’s made our relationship much stronger. Thanks sweetie!
As with my
previous account
, there’s an unwanted coda. No matter how hard I try, there’s a complication at the happy ending!
I had typed up everything above as the doctors and nurses prepared me for the first dose of methotrexate. It takes a while for your blood’s pH level to reach a point where the treatment is safe, so I spent much of the day lying in bed, peeing into urine cups, reminiscing about my year, and typing.
Around 10:30 PM, the medication was in my brain and I was trying to wind down for the night (easier said than done when part of the regimen includes steroids). While scrolling through
Tapestry
, I noticed quite a few posts about a newly announced PHP vulnerability. This caught my attention because we use it for our blogs, an ad server, delivering Kickstarter rewards, and a bunch of other small things.
(This is the point where family that doesn’t understand what I do for a living continues to not understand what I do for a living.)
It quickly became apparent that this was
a big deal
and something that could allow an attacker access to our server. I had to shut things down before my brain shut down. Thank goodness the steroids held out.
After a couple of hours, I had blocked access to PHP processes in every nook & cranny of our server. After sending a quick message to our Slack explaining how everything was broken, I collapsed.
The next day started with a head and server that were barely working. Our server was out of LTS, so the first order of business was to get it back onto the latest version of Ubuntu using hospital WiFi. It was a good thing my heart rate and blood pressure were
being closely monitored.
(Thank goodness for
Lish
, which proved to be immune to hospital IT shutting down my
ssh
connection to accept terms & conditions every few hours. There’s also a “I should have my head examined” joke in here somewhere.)
If you noticed that the Iconfactory sites were kinda broken last week, now you know why. It’s because I was kinda broken last week.
Now I’m finishing this post from a comfy chair on our deck. Typing into the latest version of WordPress and PHP. And I couldn’t be happier.
The leaked records include the locations of ICE and CBP facilities, workers' cellphone numbers, and the members of groups tied to wiretap programs, Palantir software, and xAI’s Grok chatbot.

An unprecedented leak
of
Department of Homeland Security
records has exposed details of more than 41,000 employees or contractors who work for the department and its constituent agencies. The records include email addresses, phone numbers, and office addresses, but also references to internal systems and sensitive information on undercover and surveillance programs. In all, the leak provides a map of how
DHS
is organized and how it operates.
The records, which span DHS itself as well as seven component agencies, including Immigration and Customs Enforcement and US Customs and Border Protection, were last updated on August 19, 2026. The transparency nonprofit
Distributed Denial of Secrets
and cybersecurity researcher and journalist
maia arson crimew previewed the data to WIRED, which they say they
obtained from a group calling itself the Department of Peace.
DDoSecrets published the archive, which it calls "Icepick," on Wednesday. In a press release, DDoSecrets says the data is from DHS's Okta login system. In a note with the files, the hackers wrote, “They have our information, so it's only fair that we have theirs.”
An Okta spokesperson tells WIRED that it is unaware of any breach of its systems. “We are aware of this report. Okta is secure, and we have no evidence our data or systems were compromised,” the spokesperson says.
The leak comes as DHS has aggressively
pursued its critics
, seeking to
unmask
anonymous social media users, obtain
customer records
on protestors, and
secure warrants
for surveillance tools aimed at reporters. Since the start of the second Trump administration, DHS and the federal government have moved to hide DHS employees’
names and faces
. The agency has also
expanded its definition
of “doxing”—a term that typically refers to publishing someone’s home address and other personal details for malicious purposes—to encompass the publication of basic facts about public employees, like their names and titles.
The leak follows a breach in which a group of hackers known as ShinyHunters claimed to have stolen personal information on nearly every FBI employee and their families. Law enforcement agencies have arrested several suspects and detained another who is alleged to be part of the group.
The DHS records are searchable on a website crimew built. “I don't think we should let them scare us into not looking into them,” she tells WIRED.
DHS and DOJ did not respond to WIRED’s request for comment. The FBI referred WIRED’s inquiry to DHS.
According to a WIRED analysis of the data, CBP staffers account for more than half of the records. ICE accounts for about 10,000, roughly a third of them in Homeland Security Investigations, ICE’s investigative wing. Another 6,200 belong to US Citizenship and Immigration Services, and nearly 1,000 are tied to the Cybersecurity and Infrastructure Security Agency, more than half of them contractors. Altogether, the files cover about a seventh of DHS’s workforce, revealing how DHS is structured, from senior leadership down to individual immigration agents and detention contractors.
Like most large organizations, DHS uses permission groups to control access to internal systems, according to the leaked records. Nearly everyone named in the leak has access to at least some of these systems. At HSI, 39 employees across more than a dozen field offices belong to groups whose names include “CUC,” which government court filings say stands for “certified undercover operation.” Another group, apparently based in HSI's St. Paul, Minnesota area of operations, references "Keyhole," which federal court filings describe as a certified undercover operation that recently funded
HSI's undercover surveillance of Minneapolis protest groups
earlier this year. Others reference a “Communications Intercept Center TechOps (CICTO) Program,” a “Title III Intercept Program” for wiretaps, and an “Illicit Sensor Intercept Program (ISIP).”
The names of the groups—there are over 55,000 in all—appear to reference tools for accessing immigration court records, pulling data from seized phones, and conducting surveillance. These include Palantir’s Falcon investigative platform and PenLink, which analyzes phone records and social media.
Two permission groups, named “Executive Leadership” and “AI Access,” appear to list people given exceptions to DHS's web filter, which blocks some websites for employees. They contain the same 13 people, including former DHS head Kristi Noem; Antoine McCord, the recently departed DHS chief information officer who has
returned to defense tech company Anduril
; Philip Hegseth, listed as a senior advisor to the DHS secretary and the younger brother of defense secretary Pete Hegseth; and Jayce Krachenfels, listed as a policy adviser, who previously worked as a regional field director for Donald Trump’s 2024 presidential campaign, according to his LinkedIn profile.
Other groups named in the leak reference AI tools, including OpenAI’s ChatGPT, Google’s Gemini, and Microsoft’s Copilot. One, called “Grok.com,” includes eight DHS technology officials, including the department’s former chief information officer and chief data officer.
“If authentic and current, this is an extraordinarily valuable intelligence resource for those seeking to penetrate DHS,” says Alexander Leslie, a national security expert at the threat intelligence company Recorded Future. “This dataset becomes way more valuable when correlated with previously compromised information, commercial data, and other intelligence collections. An adversary could spend months exploiting these relationships to identify vulnerable personnel, develop convincing impersonation attempts, or compromise ongoing investigations.”
More than 700 accounts are associated with a group apparently referencing
Signal
, the encrypted messaging app, nearly all belonging to CBP personnel. More than 200 CBP accounts belong to a group referencing
Mobile Fortify
, a face recognition app immigration agents use to identify people. The group includes field supervisors, special response team operators, and tactical and intelligence agents. About half are in Texas, California, and Arizona.
Roughly 1,300 ICE enforcement accounts have been created since July 4, 2025, when Trump signed the One Big Beautiful Bill Act, which funded the hiring of 10,000 new ICE Enforcement and Removal officers by the end of 2025.
Nearly 20 accounts appear to belong to personnel with the Department of Defense, which the administration styles as the Department of War; eight are in a group titled “ICE Tip Line DOW Surge.” About 170 accounts are listed as providing “military processing support” at ICE facilities, and 35 others explicitly identify National Guard members.
Dozens of accounts have job titles like “Designated Immigration Officer” and “287(g) Officer,” which mark local law enforcement personnel
authorized to carry out some immigration enforcement duties
. Many list
county sheriff's offices
and jails as their workplaces. The records also include roughly 4,400 “associates,” whose jobs range from IT developers and data scientists to nurses and detention officers. Of those, 145 are named as a “contractor” or “high risk contractor.”
More than 300 records reference senior titles associated with DHS headquarters, from Noem down through deputy undersecretaries, assistant secretaries, and chiefs of staff to officials overseeing intelligence, technology, biometrics, and privacy. Most records also name a supervisor, which could allow anyone analyzing the dataset to reconstruct reporting relationships across the department.
The Trump administration has
prosecuted protesters
for posting information about individual ICE officers and
warned others
for doing so. In June, 15 Minnesota residents were charged under laws related to stalking and threats of violence, which prosecutors linked to their participation in ICE-opposition activities.
More than 100 HSI agents
, including undercover operatives, took part in an operation that included widespread surveillance and infiltration of group chats.
Adam Steinbaugh, a senior attorney at the nonprofit civil liberties group FIRE, says that the Trump administration has taken an expansive view of
18 USC 119
, a law that prohibits people from sharing “restricted personal information” about federal officers or their families with the intent to threaten them.
"This is information that would be on a business card,” says Steinbaugh of the names and basic work details included in the archive. “That's not something the government can criminalize."
Despite the potential sensitivity of other records in the leaked data, the creators of Icepick do not consider it doxing. They see it as an accountability tool.
“The DHS especially as an agency completely lacks accountability, despite many parts of it being incredibly unpopular. The people who work there know this too, for example some of their LinkedIn bios simply say ‘stuff at US Government,’” says crimew. “If they weren't hiding their involvement in the repressive arm of the US government there would be no need for us to expose them in the first place.”

Kernel Panic
Nango (YC W23) Is Hiring Across Eng, FDE, Marketing, DevRel
We found that several PDF implementations generate their AES-256 file keys from state spaces small enough to enumerate. In MuPDF, only 9 bits of random state affect the actual AES-256 key. Other PDF editors like Foxit base their AES-256 key on time based randomness and thus also lead to keys that are trivial to recover.
Introduction
PDF encryption protects the strings and datastreams in a PDF document, including metadata unless it is explicitly left unencrypted. The password protection mechanism has gone through a bunch of revisions over the years, moving from RC4 to AES and hardening password hashing against brute force attacks. The current version, revision 6, uses AES-256.
When a PDF is encrypted with AES-256, the password does not encrypt the document directly. The implementation generates a random 32-byte file key, which encrypts the content. The password and a salt are then hashed to derive a separate key, which encrypts this random 32-byte file key. Revision 6 makes this hashing deliberately slow; the older AES-256 revision 5 does not.
A PDF can have a user password for viewing and an owner password for changing permissions. Either unlocks the same file key, so the restrictions are up to the reader: with the viewing password, you can also make an unrestricted copy.
We found that this randomness is often generated very insecurely, allowing passwordless decryption of protected PDFs.
MuPDF
MuPDF versions before 1.28.5 use an implementation of the
drand48 family
to generate their random numbers. This generator is seeded once, using the current epoch in seconds:
staticvoidfz_init_random_context(fz_context *ctx)
{
/* ... */
fz_srand48(ctx,(uint32_t)time(NULL));
}
The generator is a 48-bit linear congruential generator:
fz_srand48()
writes the state as three 16-bit words. The low word is the constant
0x330e
, and the 32-bit timestamp occupies state bits 16 to 47:
voidfz_srand48(fz_context *ctx,int32_tseed)
{
uint16_tp[3]={0x330e, seed, seed>>16};
fz_seed48(ctx, p);
}
When MuPDF needs to generate a key, it calls
fz_memrnd()
, which will repeatedly take a random number, step the random number generator forward, and then use the lowest byte of this random number as a random byte.
int32_tfz_nrand48(fz_context *ctx,uint16_ts[3])
{
returnfz_rand48_step(s,ctx->seed48+3)>>17;
}
/* in fz_memrnd() */
while(len-->0)
*data++=(unsignedchar)fz_lrand48(ctx);
The shift discards state bits 0 to 16, and the cast to
unsigned char
discards everything above bit 24. Every output byte therefore comes from bits 17 to 24 of the LCG state.
The issue is that the higher bits of the state never affect the lower bits. Multiplication and addition can carry bits upward, but not downward. Since each output byte comes from bits 17 to 24, anything above bit 24 can be ignored, even after stepping the generator forward.
That leaves 25 bits that can affect the output. The bottom 16 are always initialized to
0x330e
, so only nine bits from the timestamp matter. Timestamps that differ by 512 seconds produce exactly the same byte stream.
Since the possible keyspace is so small, we can just brute-force this by generating all possible 32-byte keys and trial decrypting:
MuPDF uses the same generator for the document
/ID
, which is stored in the trailer in plaintext. When writing a new document, it will first draw 32 bytes from the same LCG and then immediately sample the decryption key after, so
/ID
can be used as an additional check.
Searching all 512 streams in a very unoptimized python implementation using pure brute force takes about 11 milliseconds. On a test document:
That key decrypts the document without either password.
Foxit
Foxit PDF Reader 2026.1.3.36551 derives the file key as a hash of the current timestamp, 32 uninitialized bytes, and a constant. In practice these uninitialized bytes are zero filled and do not add any randomness.
The
/Perms
permissions block contains known plaintext, so the candidate check is one hash and one AES block decryption, with no password hashing and no document decryption:
// Check for some known magic values to indicate successful decryption
(plain[..4]==self.permissions
&&plain[4..8]==[0xff;4]
&&plain[8]==self.metadata
&&plain[9..12]==*b"adb")
.then_some(key)
Our Rust implementation searches timestamps downward from the current time, using Rayon for multithreading. On a Ryzen 9 7950X with 32 threads it sustains 370 to 376 million timestamps per second:
Target timestamp
Candidates tested
Search time
Ten years ago
315,573,571
0.84 s
Unix epoch
1,792,610,110
4.85 s
The second row covers every timestamp from 1970 to the present. In practice, for a document that was relatively recently generated, this will be in the order of milliseconds.
This exact pattern popped up in a couple different PDF editing suites, so we were curious where they got it from. It was already present in PDFium’s
initial public commit
from May 2014. The
file header credits Foxit for the original code
, so this code appears to have come from Foxit. Other editors may have picked it up through PDFium:
if(m_Revision>=5){
intt=(int)time(NULL);
uint8_tsha[128];
CRYPT_SHA256Start(sha);
CRYPT_SHA256Update(sha,(uint8_t*)&t,sizeoft);
CRYPT_SHA256Update(sha,m_EncryptKey,32);
CRYPT_SHA256Update(sha,(uint8_t*)"there",5);
CRYPT_SHA256Finish(sha,m_EncryptKey);
/* ... */
The 32-byte middle value is
m_EncryptKey
, which is the uninitialized contents of the key buffer being hashed into itself. Assuming these bytes are zero filled, this is exactly the key derivation Foxit still uses today.
OpenPDF and iText
OpenPDF 3.0.5 and iText 9.7.1 both route cryptographic randomness through an
IVGenerator
class, an ARC4 stream seeded with a millisecond timestamp and the JVM’s free memory:
arcfour =newARCFOUREncryption();
longtime=System.currentTimeMillis();
longmem=Runtime.getRuntime().freeMemory();
Strings= time +"+"+ mem;
arcfour.prepareARCFOURKey(s.getBytes());
The same stream generates the file key and 32 bytes of salts stored in plaintext in
/U
and
/O
. We can check guesses for the timestamp and free memory against these salts, then recover the key from the adjacent bytes.
While there is significantly more variance here than in the MuPDF and Foxit examples, this once again shows that the promise of 256 bit security is undermined by insecure randomness sources and lower-than-advertised state space.
Conclusion
In each of these implementations, the file key is generated from a non-cryptographically secure source of randomness. What was supposed to be a security upgrade over older file keys derived from the user’s password instead led to weaker keys in practice. These issues were disclosed to the vendors and, in MuPDF’s case, fixed. Previously published copies cannot be retroactively protected, however, so these bugs may still have an impact.

U.S. law enforcement has seized the primary domain of Virtualine, a bulletproof hosting service advertised on cybercrime forums for facilitating illegal activities.
The service also operated under the names Secury, Massgod, Spamhouse, Lanedo, and Omegatech, and promised to shield customers from legal complaints and requests from law enforcement and other authorities.
The U.S. Department of Justice (DOJ) confirmed that Virtualine marketed services that permitted “illegal/black hat activities” ranging from phishing, spamming, and carding to port scanning.
The FBI seized the primary domain of the service, virtualine[.net], following an investigation that involved Germany’s Polizei Hessen, the Netherlands’ Politie Midden-Nederland, the U.K.’s National Crime Agency, as well as private partners OverRIPE and Lumen.

Although Virtualine drew an apparent line at child content, authorities say that the operator knowingly hosted an online forum promoting child abuse material and ignored repeated notices from law enforcement, the National Center for Missing and Exploited Children (NCMEC), and a victim’s attorney.
Authorities allege that after legal pressure against the forum increased, Virtualine worked with the administrators to set up a new site.
"Virtualine hosts this new website to this day, and it has already received at least one abuse complaint about sexually explicit images of children found on that website," the
DoJ said
.
The administrator of the Virtualine rejected the allegation in an open letter to authorities published on a new website, virtualine[.]org, captured by cybersecurity company
Silent Push
.
The operator said that while claims about the service's illegal activities and customers "deserve a fair investigation," they regarded "sexual exploitation of children as a crime against humanity."
Cybercrime ecosystem
Virtualine also accepted direct Bitcoin payments from customers, helping cybercriminals launder proceeds stolen elsewhere.
Blockchain intelligence firm Chainalysis, which provided intelligence support to law enforcement, linked Virtualine’s payment addresses directly to ransomware operators, infostealer infrastructure, Russian-language cybercrime forums, illicit shops, scams, and phishing platforms.
“Virtualine accepted direct bitcoin payments through unhosted wallet addresses, allowing criminal customers to pay without flagging their funds through hosted exchange compliance programs,”
Chainalysis notes
.
“Virtualine then laundered those proceeds to conceal their origin,” the blockchain company added.
In a report published today, blockchain intelligence firm
TRM said
ransomware groups were responsible for 5% of Virtualine’s financial flows, while a Russian drug marketplace made up approximately 44%.
"A large sextortion scheme and a mixer were also major sources of funds," the company said.

TRM says that Virtualine also received payments from the StealC infostealer this year, with transactions indicating a constant financial relationship.
Politie also said its investigators recovered data from more than 3,000 Virtualine customers, and follow-up action against them is underway.
According to the authorities in the Netherlands, the illegal platform was facilitating cybercrime operations since at least 2022, including ransomware, botnets, infostealers, phishing, and distribution of child abuse material.
Although the bulletproof hosting provider remains partially online, researchers observed that its network prefixes currently have very low routing visibility, suggesting that much of its infrastructure may no longer be reachable.

Google AI gets cagey when asked who won the 2020 elections
In the most recent update to Apple’s devices, iOS 27.2, the company has introduced a new setting to “Exclude Apps” from Siri AI, fulfilling one of our asks from our Encrypt It Already campaign earlier this year.

In the most recent update to Apple’s devices, iOS 27.2, the company has introduced a new setting to “Exclude Apps” from Siri AI, fulfilling one of our asks from
our Encrypt It Already campaign earlier this year
.
One of our main concerns with new AI features on devices is how those features interact with end-to-end encrypted content, particularly with secure messaging apps. Many AI features require cloud processing, and despite
privacy protections engineered into these systems
, the content of secure messaging apps may leave a user’s device without their knowledge. That changes the privacy concerns around using those tools. In a perfect world, users would be able to put a barrier up to ensure data from certain apps doesn’t leave the device. Here was our initial ask:
You should be able to tell the operating system’s AI to not access an app, even if that comes at the “cost” of missing out on some features. The setting should be straightforward and easy to understand in ways the Gemini and Apple Intelligence controls currently are not.
At launch, we found the settings to control Siri AI’s app access
behavior pretty confusing
. You had to toggle several options to block Siri AI off from accessing an app, or disable Siri AI entirely. Turning off Siri AI and
reverting to Siri Classic
is, for now, still a good option if you’d prefer to use the older version.
The most recent update is far more clear and does more to protect your data. And, just as expected, it comes at the cost of some features. That’s a good thing, actually. The features not working shows that the new setting is effective.
Here’s how to add apps to the exclusion list, once you’ve updated to 27.2:
Open
Settings
>
Siri
>
Excluded Apps
Tap “Add Apps” and select any apps you’d like to add to the exclusion list
Now Siri AI cannot access the contents of the app. Excluding an app also means you may lose some features. For example, if you exclude the Apple Messages app, you will no longer be able to have Siri AI read or respond to messages for you. Even the “onscreen awareness” feature, where you invoke Siri and ask it for information about what you’re currently looking at, will not work anymore. For example, if you exclude Signal, you cannot invoke Siri and ask it to discern any information in the Signal app. You’ll just get these messages:
What’s the State of This on Android?
This update from Apple is also a good excuse to check in on the process on Android. It has improved a little, but is
not as straightforward
as Apple’s new settings, and lacks the ability to set the screen context feature per-app. But you do have some control over what Gemini can access:
Open up the Gemini app
Tap your user photo, then
Settings > Personal Intelligence
>
Connected Apps
Revoke access to any apps you do not want Gemini to have access to
This process seems to work well enough for some data and we like that it’s opt in, but it’s not exactly intuitive. For example, Signal doesn’t appear there because Signal doesn’t support Gemini’s app access feature at all. That means Gemini can’t access the content of Signal directly, which is good.
But Gemini can read notifications if you’ve enabled the “
Device Assistance
” Connected App (which you likely have, since that also enables basic features, like setting a timer—check under
Settings
>
Personal Intelligence
>
Connected Apps
), and it can use screen context unless you’ve disabled the
Device controls
>
Screen context
> “Use screen and app data” option in the Gemini Settings. These two features may access the contents of the Signal app or notifications, if you choose to use them. We’d prefer a more hard-lined approach that reduces the chances of user error here: Google should give users the ability to turn these features off per app.
Apple clearly understands that some users want stronger controls over what Siri AI can and cannot access. But we think they should go further and offer the option to only use “on device” AI features, similar to
what Samsung offered with its Galaxy AI
. We’re happy to see this change and think all operating systems need to consider similar controls moving forward.
Court Should Curb Abuse of Grand Jury Subpoenas Targeting Social Media Users

A federal appeals court should curb the government’s abuse of grand jury subpoenas to unmask social media users who criticize lawless immigration enforcement.
That is the message from the ACLU, EFF, and other civil liberties and trade groups who filed
a friend-of-the-court brief
in a sealed case in the U.S. Court of Appeals for the District of Columbia.
The case involves
the government’s investigation of an anonymous Reddit user who commented on a post about an immigration officer in Minnesota. The Department of Homeland Security (DHS) first issued an administrative subpoena to Reddit to unmask the user. When the user challenged the subpoena in court on free speech and statutory grounds (
as many others have
), DHS withdrew it. But then the government obtained a separate grand jury subpoena—a subpoena issued by a prosecutor to gather evidence to present to a grand jury before any criminal charges are filed—for much of the same information. The user then challenged the grand jury subpoena too, and the case is currently being appealed.
The right to speak anonymously is essential. It preserves privacy and shields critics from government retaliation. In the past year, the Department of Justice (DOJ) has issued grand jury subpoenas to social media companies for their users’ personal data. This is frequently done for improper purposes and without really showing that social media users have committed any crime. These subpoenas have the effect of intimidating and chilling critics, as immigration authorities have engaged in
invasive
,
unconstitutional
, and
sometimes violent conduct
.
As the amicus brief makes clear, courts should not defer to the government’s claims regarding the legitimacy of using grand jury subpoenas to unmask internet users. Instead, the subpoenas must receive proper First Amendment scrutiny. Like many other types of legal processes, grand jury subpoenas are issued by federal officials without prior court approval. And they too can be abused to harass or retaliate against people critical of the government.
The amicus brief was filed in early September and recently unsealed. The brief was signed by the American Civil Liberties Union of DC, EFF, the Center for Individual Rights, the Foundation for Individual Rights and Expression, the Cato Institute, and NetChoice.
It is notable that NetChoice signed the amicus brief. It is a trade group that represents many companies who have received similar subpoenas including Reddit, Google, Meta, PayPal, among others.
EFF has called on these companies
to do more to defend their users’ speech and privacy rights in the face of these subpoenas.
Discord to let search engines index public server messages

Discord will allow search engines to index discussions in Discoverable Servers and make them accessible on the web to users outside the platform without an account or invitation.
The goal is to surface useful information to the wider internet community instead of keeping it buried in Discord conversations.
“Discussions in Discoverable Servers will soon be easier to find when you search the web, so you can find the answer you’re looking for and step straight into the conversation on Discord,” the
messaging platform explains
.
The changes apply only to Discoverable Servers, publicly listed communities with at least 1,000 members. The platform says it hosts approximately 63,000 such servers.
This decision excludes private servers, direct messages between users, and group announcements on servers that don’t meet the requirements.
According to the company's schedule, the rollout will happen in two stages:
On November 16, every Discoverable Server will get a public Server Web Page which will display automatically generated summaries of active conversations from that date onward.
Starting mid-December, every eligible message posted on Discoverable Servers will appear on the Server Web Page and may be indexed by web search engines.
Server Web Pages will be automatically created on November 16 if admins haven’t created them by then, and the only way to avoid them is to change the server type to private before the cutoff date.
Discord has been piloting Community Messages and Server Web Pages in the NBA 2K, Rust, and Dead by Daylight gaming groups.

The December rollout will be gradual, and Discord says messages posted before the release date will be excluded.
Channel administrators can choose to exclude individual channels or turn off all channel content sharing entirely using controls available under
Server Settings > Web Presence
.
Administrator data exposure setting
Source: Discord
Community members can also control if their messages appear on the Server Web Page through
User Settings > Data and Privacy
. However, changing that setting only affects future messages, and past messages that became public cannot be retracted.
User data privacy setting

If admins and users leave the settings at their defaults, their content will automatically be included in the new sharing scheme.
However, message sharing will stay off by default in all EU countries, the UK, Canada, Brazil, Australia, and South Korea. In those places, members must explicitly enable it in their privacy settings.
Underage users are automatically excluded and cannot activate the feature until they turn 18.
Trump Vows to Send Election “Monitors” to Maine After Far-Right Conspiracies Spread
Intercept

2026-10-28 14:36:46
As right-wing Trump allies fearmongered about Somali American voter fraud, Maine trained local law enforcement officers on keeping armed federal agents out.
The post Trump Vows to Send Election “Monitors” to Maine After Far-Right Conspiracies Spread appeared first on The Intercept....
With voters set
to cast ballots in two critical races that could help determine control of both chambers of the U.S. Congress, fears of potential voter suppression are running high in Maine.
Officials in the state have prepared for months against the possibility of election interference from federal officials, and the state remains on high alert in the run-up to the general election on November 3.
Training materials were updated this year to include references to federal statutes barring armed federal agents from polling sites.
Training materials
for law enforcement officials in the state, obtained by The Intercept through a public records request, were updated this year for the elections to include explicit references to federal statutes barring armed federal agents from polling sites.
In an interview with the
New York Times
this week, Maine Secretary of State Shenna Bellows said the inclusion of such references was a direct defense in response to the fearmongering around election integrity from President Donald Trump and his administration.
“This is the first time ever that we have had to engage in scenario planning to safeguard against potential federal interference in elections,” Bellows said. “It seems like the federal government is now adversarial to the states.”
Bellows’s office offered up the training slideshow, which cites a U.S.
law
that bars armed civil or military officers from posting at voting sites, to law enforcement personnel in the run-up to Maine’s primary election in June and again in the lead-up to the general election on November 5.
Nationwide, Democratic officials have expressed
fears
that the Trump Administration might weaponize U.S. Immigration and Customs Enforcement or other federal agencies to undermine the rights of voters. In New York, state Attorney General Letitia James issued a
reminder to voters
that federal officials may not “police the polls,” and the Arkansas chapter of the NAACP called out the assignment of federal election monitors to two counties in the state as
potential intimidation
.
The Trump administration, meanwhile, has sounded the alarm about the alleged scourge of non-citizens on the voter rolls,
sending agents
from the FBI and ICE’s Homeland Security Investigations division to
probe alleged fraud
. A handful of people in
California
,
New York
, and
North Carolina
have been indicted for allegedly voting as non-citizens, but a review of similar cases by the
Washington Post
found that such cases were often the result of honest mistakes.
In Maine, worries about federal interventions at polling places flared when — following a slew of social media videos from Trump allies suggesting that fraud is already taking place among the state’s Somali American community — a local outlet
reported
that the Department of Justice would be sending election monitors to the state.
Jon Fetherston, a journalist with the far-right Maine Wire, which is
funded
by conservative megadonor Leonard Leo, was seen
following people in and around an early voting site
at Lewiston City Hall and aggressively questioning them. (The Maine Wire did not immediately respond to a request for comment.)
Critics said the moves were tantamount to voter harassment, but Maine Wire editor-in-chief Steve Robinson later defended them as an act of election transparency. Robinson, who has led a crusade against what he alleges to be a network of fraud in the state’s Somali American community, questioned the role of interpreters tasked with helping “jobless Somali bums” cast their ballots.
In the wake of the Maine Wire controversy in Lewiston, Bellows
confirmed
to the Maine Morning Star that a wave of federal election monitors would be headed to polling sites in Lewiston and Portland.
The Department of Justice on Tuesday confirmed to The Intercept that it intends to send election monitors to Maine for Election Day, but did not elaborate or respond to specific questions about where the monitors were to be sent.
“We will have around 1,000 monitors in counties throughout the United States, but we will not share the full list until Election Day,” a Justice Department spokesperson told The Intercept in an email Tuesday. “All monitors must meet the same legal and ethical requirements, including that they not interfere with the voting process. Every monitor has the same role: observe for potential violations of federal law and report concerns to the Department, which the Department will review after Election Day and act where appropriate.”
Robinson did not immediately respond to a request for comment.
Collins Takes Right-Wing Bait
With Maine a key battleground state for control of Congress — Democratic challenger Troy Jackson is seeking to topple
long-serving
GOP Sen.
Susan Collins
, and the Democratic House candidate Matt Dunlap is seeking to best former Gov. Paul LePage in Maine’s 2nd Congressional District — temperatures are running high in the state.
Progressives in Maine worry that even without a robust federal presence at voting places — whether monitors are armed or not — activist campaigns like the one undertaken by the Maine Wire journalists could pose a potential threat to voters’ rights.
“Basically, if you were walking into City Hall and you were Black, you could expect to have this guy come up to you with his phone and ask you all sorts of rude and obviously racist questions,” said Ben Chin, co-director of the progressive Maine People’s Alliance. “We’re trying to encourage everyone to come out to vote, but it makes sense why that might give people pause. You hear a guy like that is outside a polling location, it’s reasonable to wonder, ‘Should I go down there right now?’”
“We have received complaints about the intrusive filming, photography, and harassment of voters in the City of Lewiston by political operatives.”
In a statement to The Intercept, Bellows said the state and the city of Lewiston were taking steps to ensure that voters could cast a ballot free of harassment.
“We have received complaints about the intrusive filming, photography, and harassment of voters in the City of Lewiston by political operatives,” Bellows told The Intercept in a statement. “All voters should be able to exercise their right to vote without feeling watched, questioned, or harassed, and we take these allegations seriously, particularly when it appears that voters were targeted for no other reason than their race or ethnicity. We understand the City of Lewiston has taken steps to address the problem, and we will continue to monitor the situation.”
Collins, meanwhile, took the Maine Wire’s reporting seriously after Fetherston asked the senator at a campaign event about the role of interpreters, which he and the Maine Wire cast as “
electioneering
.”
“I’m unaware of those allegations, but certainly only Americans should be voting in American elections,” Collins said. “And it is troubling to me if people are being accompanied into voting booths and handling ballots in a way that is not sanctioned by law.”
Big Tech's thirst for water is sparking a global resistance
After ChatGPT was released in November 2022, the tech industry was quick to herald the chatbot as the marker of a new wave of technological progress. As companies pushed to create more powerful AI models, the water demand of their ambitions took a while to become clear. In April 2023, a
research paper
out of the University of California estimated that training the large language model behind the initial version of ChatGPT had required 185,000 gallons of water. For every extended conversation someone had with the chatbot or every time they asked it to write an email, they were effectively pouring a bottle of water down the drain.
That statistic got a lot of play when it was released. It became an early warning sign of what was coming as companies pushed chatbots as a universal technology that could replace psychologists,
educators
, lawyers, and even people’s friends or
partners
.
As public concern grew,
Google
and OpenAI came out with their own figures. The companies suggested that querying one of their chatbots used mere drops of water. Independent researchers were not impressed, arguing the companies were taking a narrow view of the water use necessary to power and cool increasingly monstrous data centers. Those water demands can be quite significant too.
A hyperscale data center can suck up between 1 and 5 million gallons of water a day, comparable to the amount used by a city of 10,000 to 50,000 people — depending on the part of the world we’re talking about. Consider how these companies often cluster data centers together and it becomes obvious what a challenge it can be to supply them.
Data centers end up competing with communities over their potable water supply.
The water demands of individual data centers are also continuing to grow. It’s not just that they need more water for cooling as they become larger and contain more servers. The graphics processing units (GPUs) that power generative AI are much more resource-intensive than the chips and storage devices that traditionally filled data center racks. GPUs run harder and
throw off more heat
, meaning they also need more energy or water to keep them cool.
Data centers cannot just use any kind of water either; it has to be clean enough to ensure the equipment and pipes are not damaged. Tapping into public drinking water is both easier and cheaper than paying the cost of treatment themselves. That means data centers end up
competing with communities
over their potable water supply.
If we want to look at a part of the world where the issue of data center water use has taken center stage, there are few better countries to turn to than Chile. In October 2019, mass social demonstrations broke out across the country. One of the movement’s driving slogans was about water. It was poor timing for Google as it was fighting for approval and public support of its latest data center project, a $200 million data center project in Cerrillos, on the southwest side of Santiago.
The company made a pitch similar to the one residents in communities the world over have heard whenever a data center is proposed: that the facility would bring jobs and prosperity, and give the area a leg up on further tech investments. The reality was not so straightforward. Google’s new data center would bring a lot of short-term construction jobs but not much
long-term employment
. And it would need a lot of water — something Cerrillos did not have much of to spare.
Local residents
were not as passive
as the company had hoped. A group of concerned citizens established an organization called MOSACAT, which stands for Community Socio-Environmental Movement for Water and Land, and started poring over whatever information they could get their hands on to try to understand what the project would mean for them. “Usually these reports use quite technical language, and this is a working- class community where not many people are lawyers, for example, or experts on ecology,” explains Sebastián Lehuedé, a researcher at King’s College London who is from Chile and spent time in Cerrillos.
Data center companies claim they will be respectful and considerate neighbors, but too often hide the extent of the damage from the scale of their demands on local resources.
According to its own projections, the data center Google wanted to build in Cerrillos was poised to use 169 liters of water every single second. In just one day, the data center would consume as much water as all 80,000 residents of Cerrillos use for drinking in a year. To make matters worse, it wanted to draw that water from an underground aquifer that had been under a decree that restricted how much water could be removed since 2005. Just weeks before the project was rubber-stamped by the environmental authority, that decree had been upgraded to a complete prohibition on new extraction.
The water use estimates set off alarm bells for the residents. Chile had already been in an unprecedented drought since 2010. By 2021, more than half the country’s 19 million residents lived in areas experiencing severe water scarcity, forcing hundreds of rural communities to rely on tankers to deliver drinking water.
The local activists ultimately built the case against one of the largest companies on the planet. After months of meetings and advocacy to spread awareness, they were able to put a referendum question to the residents of Cerrillos about the project in December 2019. The results were damning: 49% of voters chose to reject the project, while 38% wanted it to go forward.
After both the municipality and community members filed claims against Google in 2020, the company returned with a new proposal in February 2022. It offered to cool the data center exclusively with air-conditioning rather than with water.
Across the city in Quilicura, opposition was building too. Microsoft announced its intention to build a data center in the community in 2022, the same year strict water-rationing rules had come into effect in Santiago. As in Cerrillos, residents were worried that another large data center would threaten their access to water and
provide little in return
.
Vicente Bardales, a member of the Quilicura Socio Environmental Resistance group, told
Rest of World
that the companies touch down in places like Quilicura only to “use water, [and] dry up the territory, but don’t give anything back to the population.”
Only a tiny proportion of water in Uruguay is used for human consumption.”
Daniel Pena, researcher at University of the Republic.
Similar scenarios to that of Chile played out across Latin America. The following year, the Uruguayan capital of Montevideo found itself under a state of emergency as the country was hit by its worst drought in 70 years. As residents demonstrated against the misuse of water by industry, they found out Google was planning a data center in Canelones, a little less than an hour north of Montevideo.
“Only a tiny proportion of water in Uruguay is used for human consumption,” explained Daniel Pena, a researcher at University of the Republic. “The majority is used for big agro industries, such as soya, rice, and wood pulping. Now we have Google planning to use enormous quantities of water.” Pena had to go to court to get details of its planned water use from the Ministry of Environment, ultimately finding Google’s 72-acre site was planning to use 2 million gallons of water each day to power its cooling systems.
Uruguayans had fought for fresh drinking water to be considered a basic right in the national constitution two decades earlier, and as companies like Google moved in, they feared its realization was slipping from their grasp.
Uruguayans suspected Google had shifted its focus to their country because it had run into such opposition in Chile. Neighboring Brazil already has over 180 data centers, even as many regions regularly experience drought conditions. On the outskirts of Fortaleza, Brazil’s fourth-largest city, at least four major data centers were looking to set up shop to take advantage of a free-trade zone in the municipality of Caucaia. One in particular would be the size of 12 football fields, costing an estimated $10 billion, and though it will technically be owned by a local wind energy company, it is actually being developed t
o serve TikTok
. This is in a region that experienced emergency drought conditions for 16 of the 21 years between 2003 and 2024.
What Cerillos, Canelones, and Caucaia are experiencing is increasingly
a global phenomenon
. Around the world, data center companies claim they will be respectful and considerate neighbors, but too often they hide the extent of the damage that follows from the scale of their demands on local resources. This is particularly acute in parts of the Global South, but the effects are now also being felt across the United States and Europe.

Since Richard Sutton’s
influential essay
in 2019, the concept of the
bitter lesson
has guided much of modern progress in AI. This concept espouses general methods that leverage computation and learn with scale, as free of human-engineered priors as possible. Our interpretation is that, fundamentally,
intelligence is about learning from raw data
: autonomously finding patterns, building abstractions, and developing meaning from messy low-level inputs, ideally
end-to-end
and as data-efficiently as possible. As AI advances into complex domains such as science, robotics, and biology – where data is scarce and often difficult for humans to understand, let alone engineer for – internalizing this philosophy to develop more general learning algorithms is more important than ever.
Language models are perhaps AI’s biggest success story today, and largely embrace the bitter lesson. Their abilities are largely attributable to scaling a few simple algorithms such as the Transformer architecture, next-token prediction, reinforcement learning, and test-time computation. However, they still rely on hand-crafted encoding steps such as tokenizers, which severely hinder their ability to learn end-to-end from the underlying data. Towards unlocking another step change of scaling,
we believe that developing byte-level language models is foundational for AI progress
– not just for improving standalone LLMs, but also as a litmus test for general learning methods. If we can’t even learn language well from characters and bytes, what right do we have to make progress on the next frontier?
In 2025, we developed the concept of
hierarchical networks (H-Nets)
, which not only addressed tokenization in language models, but took a step toward even more general-purpose architectures that could learn from raw data across different modalities. We’ve since significantly improved the technology of H-Nets and are excited to share their capabilities! In this series of two posts, we’ll dig into new results and discuss the implications.
In this first post of a two-part series, we’ll explore scaling laws for H-Nets and their qualitative behaviors.
We produce a standard scaling ladder for tokenized Transformers, and show that carefully controlled 1-stage
H-Nets provide meaningful compute efficiency gains
(up to 3-5x) purely through
learned tokenization.
We show empirical results from scaling up a more flexible 2-stage H-Net, where it
outperforms a matched open-source model
with
extreme efficiency improvements (10x less compute and data).
We analyze the patterns that H-Nets learn, where they show a
rich diversity of new behaviors
previously unseen in language models, such as
in-context tokenization.
We discuss how H-Nets go beyond language modeling, with ongoing research results in biology and vision, showing promise as a
general architecture across modalities.
In the
next post
, we’ll do a deeper exploration of a larger range of models to understand better why H-Nets can be so much more efficient for language modeling.
Altogether, our results provide evidence that H-Nets are a foundational architecture that
truly aligns with the bitter lesson
, learning meaning directly from raw data and significantly improving efficiency and scalability. This research agenda represents a major opportunity to advance how AI can learn from all data, and we couldn’t be more excited to push the frontier!
Hierarchical Networks (H-Nets)
We introduced hierarchical networks (
paper
,
blog
) last year as a new end-to-end architecture that models multiple levels of abstraction in data, showing promise in language modeling and beyond. In a nutshell:
The terminology was inspired by the existing concept of
chunking
in cognitive psychology, which is an essential part of human intelligence. We believe it is also necessary for the frontier of artificial intelligence.
In the context of language modeling, the idea is to build new learning primitives that allow models to recursively chunk low-level data into higher-level meaning: characters into words, words into phrases, phrases into concepts.
In the context of this post, for the most part, one can think of hierarchical networks as replacing tokenization. Instead of pre-processing data from bytes into tokens (fixed chunks of bytes), H-Nets perform the chunking
dynamically
directly inside the model. Furthermore, the signature characterization of H-Nets is that they hierarchically perform this chunking
end-to-end
. In contrast, standard tokenized language models and even other alternatives (some of which we’ll see in
Post II
) employ multiple stages of training, and the process of chunking / tokenizing the data is performed entirely offline.
Details: Tokenization and BPE
Language models don’t read text directly but instead take as input a sequence of tokens from a fixed vocabulary. A natural vocabulary is the 256 byte values, producing one token per UTF-8 byte. Byte-level sequences, however, are long and expensive for standard language models to process. Tokenization aims to alleviate this problem by compressing the byte sequence into frequently occurring chunks. The most common approach, Byte Pair Encoding (BPE), starts from the 256 bytes and repeatedly merges the most frequent pair of adjacent tokens on a fixed training corpus, until the vocabulary reaches a set size (e.g. 128k for Llama-3). On our data mix, each BPE token covers about 4.57 bytes, making sequences much shorter than at the byte level. However, this compression is fixed, and tokenization remains one of the last parts of the language-modeling pipeline that is designed by hand rather than learned.
We’ll see in this post series that even in the narrower context of replacing tokenization, the end-to-end property of H-Nets provides real performance gains. Beyond tokenization, H-Nets have broad utility as a foundational architecture:
H-Nets can be nested recursively, allowing for multiple levels of abstraction to be built. The
main result
of this post is a larger two-stage hierarchical network matched against an open-source baseline.
H-Nets can operate over any type of data, not just bytes, and not just discrete data. In contrast, tokenizing continuous data is a serious challenge. In the
final part
of this post, we’ll preview some future research applying H-Nets beyond text.

The hierarchical network (H-Net) architecture. Inputs go through a series of 5 modules: (1) an encoder reads the inputs, such as bytes; (2) a learned chunking step compresses them into a few chunks; (3) the main network operates over coarse chunks (analogous to tokens); (4) the chunks are decompressed back into the input resolution and summed with a residual; (5) a decoder finishes processing the combined representations. A 1-stage H-Net performs one level of dynamic chunking; the main network itself can be an H-Net, allowing the chunking process to be recursively nested. Hover over different bytes to see how they’re routed through this 2-stage hierarchical network!
Figure 1
illustrates a 2-stage H-Net and defines the main components of the model: the encoder, main network, and decoder. We sometimes call the encoder/decoder together the
outer networks
and the main model the
inner network
.
Throughout this post, we show results with a much improved version of H-Nets, which we plan to release. We’ll comment more on differences from the earlier architecture
later in this post
.
Part 1: BPE and H-Net Scaling Ladders
As with many architecture papers, the original paper on hierarchical networks focused on tuning language models of particular fixed sizes and data horizons (e.g. ~1.3B-parameter models on 100B tokens from FineWeb-Edu have been very common). Although they looked very promising, a missing piece was the lack of compute-optimal scaling laws, now a standard way to measure pretraining innovations. For example, Kimi’s popular innovations on
Kimi Delta Attention (KDA)
and
attention residuals
measured compute multipliers of 1.16x and 1.25x, respectively.
In order to validate the gains of our improved H-Net architecture, we first set out to build a modern LLM scaling ladder, and then replaced its tokenization components with a carefully controlled hierarchical network.
We set up a training mixture for comparing byte-level and BPE scaling laws on equal terms, carefully matching the processing and even re-training a BPE tokenizer for the baseline.
We set up a scaling ladder for a baseline BPE Transformer language model according to standard practices, reproducing results from the literature.
We then converted each rung to a byte-level H-Net as a drop-in replacement, reusing the BPE backbone architecture and hyperparameters.
This recipe directly showed stronger results on validation loss (1.3x), with gains increasing on subdomains such as code (2x), as well as improving out of distribution (2x on evaluation, and up to 5x on out-of-domain code).
A data-controlled comparison
Since byte-level and BPE models process the same data at different granularities, extra care is needed to keep the methodology controlled.
Data mixture
: Our training dataset consisted of 70% English, 20% code, 5% math, and 5% multilingual, measured by the number of bytes.
Data processing
: Every sample is processed as both bytes and BPE tokens, splitting at the same boundaries; both byte- and BPE- processed datasets therefore contain exactly the same text with aligned document boundaries.
Metric
: We use the standard bits-per-byte (bpb) metric for measuring next-token prediction loss in a way normalized between different tokenizers.
In-corpus BPE tokenizer
: LLMs generally use off-the-shelf BPE tokenizers; an advantage of H-Nets is that they learn their chunking directly on the training distribution. To be extra careful, we also trained a BPE tokenizer on the corpus. We used this for the BPE scaling laws below, which ended up resulting in about a 1.1x compute gain on both validation loss and downstream evals (so the H-Net would have an even greater compute multiplier against a standard off-the-shelf tokenizer!).
The BPE tokenizer’s vocab size is 128k, matching the Llama-3 tokenizer that we were working off of. The in-corpus tokenizer compressed the dataset slightly more, increasing the average BPE token length from 4.45 (Llama-3 tokenizer) to 4.57. Measured in tokens of the in-corpus BPE tokenizer, the training dataset comprised 64.7% English, 23.7% code, 6.1% math, and 5.5% multilingual.

How much the BPE tokenizers compress each source in the pretraining mix, in UTF-8 bytes per token. Each bar is a source's total bytes over its total tokens. Out of the four categories, English web text packs the most bytes into each token because BPE is biased toward data frequency; code, math, and most other languages use fewer.
Creating a robust BPE baseline
For our baseline, we fit a well-tuned scaling law for a standard BPE Transformer. To do this, we constructed a scaling ladder, following modern scaling recipes such as
Kimi
and
MAI
, fully defining a family of models by the number of layers
L
. We set the hidden dimension
D
to a multiple of 128 such that the aspect ratio
D
/
L
is approximately 75. For all models, we use multi-head attention with the number of heads equal to the number of layers and a fixed head dimension of 128. For the MLPs, we use SwiGLU layers with the intermediate dimension set to 3.6
D
, again rounding to the nearest multiple of 128.

Table 1.
Example rungs from the BPE Transformer ladder. Rungs are named by depth, and width grows with depth. Every rung uses 128-dimensional attention heads, with one key/value head per query head. Backbone parameters exclude the token embedding and output layers.
We then fit compute-optimal scaling laws with the standard iso-FLOP sweep methodology.
All runs use the Muon optimizer and WSD learning rate schedule with fixed-fraction warmup and decay.
We tuned batch size and learning rate on selected rungs and fitted hyperparameter scaling laws to extrapolate to larger ones.
We counted FLOPs carefully in all models, including all sequence-mixing layers and the LM head. For softmax attention, we also count only causal FLOPs, as, due to the quadratic complexity, over-counting non-causal FLOPs penalizes byte-level models which process longer sequences.
An equivalent H-Net ladder
Because H-Nets over bytes are so different from standard tokenized models, it’s highly nontrivial to compare them directly. There are so many moving parts: how many stages of chunking, the respective compression rates, the architecture configurations of each stage (outer vs. inner networks), and the hyperparameters for each component.
We decided to investigate a narrower setting: how do H-Nets compare against BPE models, if restricted to being interpreted as purely replacing the tokenization portion of the language model?
To do this, we converted each rung of the BPE ladder to a
byte-level 1-stage H-Net
. A 1-stage H-Net can be viewed as a standard language model with learned tokenization: the inner network operates over chunks (which play the role of tokens) and the outer networks perform the role of
dynamic
tokenization, encoding bytes into chunks and decoding them back. Each rung is matched very carefully:
The H-Net’s inner network is exactly the same Transformer architecture.
The H-Net’s outer network (encoder and decoder) is FLOP- and parameter- matched to the tokenization layers (embedding and “unembedding” or projection head).
The H-Net’s compression ratio is matched to the BPE compression rate (4.57) by using a strong auxiliary loss.
The BPE Transformer’s hyperparameters (batch size and learning rate) are directly transferred.
Converting a BPE rung into an H-Net
One rung of the ladder

Converting one rung of the BPE ladder into a byte-level 1-stage H-Net. The main backbone keeps the same architecture and runs on units of about 4.5 bytes in both models. The H-Net’s outer networks replace the tokenization layers and are matched to them in total parameters and FLOPs.

Figure 4.
Compute-optimal scaling of the BPE Transformer ladder and matched H-Net models. The H-Net reaches the BPE Transformer's loss with 22% less compute on held-out pretraining data (validation bpb), and the gap widens on downstream evaluation suites.
At all model sizes,
the H-Net run achieved lower loss than the matching BPE Transformer rung
– the “dynamic tokenization” interpretation outperformed the static tokenizer out of the box!
After fitting compute-to-loss power laws to both ladders, we can compare the compute efficiency of both architectures, quantified by how much less compute the H-Net takes to reach the same loss as the BPE ladder (
Figure 4
).
In-domain
: The H-Net is 1.28x more compute efficient than the BPE Transformer.
Evaluations
: We examined standard downstream evaluation suites such as
Paloma
and
OLMES
, each of which consists of a mixture of dozens of datasets and tasks spanning human languages and domains (code, math, etc.). For each one, we measured the “soft accuracy” of a model as the bits-per-byte it assigns to the correct answer. Re-fitting compute-to-bpb scaling laws to each suite, we see that the gap between H-Nets and BPE Transformers grows further to around 2x.
In
the second post of this series
, we analyze the out-of-distribution behavior of a range of language models more deeply, providing support for the hypothesis that more flexible and semantic chunking leads to stronger downstream transfer.
Compute multipliers: code
Interestingly, H-Nets particularly excel on code. Fitting the same laws to each programming language it was trained on, the H-Net’s compute multiplier rises for all 15 languages: from 1.49x on Markdown to 2.40x on Go, with a median of 2.04x (
Figure 5
).
The gains are larger still on languages outside the training mix. On ten Stack v2 languages that were not part of the data mix, including OCaml, Prolog, Lean, and Fortran, H-Net’s multiplier rises to a median of 3.10x, from 2.19x on Haskell to
5.37x
on Prolog.
(Why is this important? LLMs are often asked to work with code they may not have seen much data for, and are increasingly used to invent or reason over new languages such as DSLs, kernel programming languages, and hardware abstraction layers. So OOD code performance may actually be quite meaningful to frontier models.)

Figure 5.
Compute multiplier on code, one language at a time: how much more compute BPE needs to match the H-Net. The H-Net’s compute efficiency grows on code, from 1.49× (Markdown) to 2.40× (Go) on the 15 languages in the training mix (In distribution), and further on 10 languages outside it (Out of distribution), from 2.19× (Haskell) to 5.37× (Prolog). Scroll the list or use the arrows to move between languages.
Intuitively, we hypothesize these phenomena arise for a few reasons:
H-Nets perform better on new distributions in general because they learn how to create semantic concepts from lower-level data, which generalize better. This is reflected in the rise from in-distribution (1.28x) to downstream evaluations (2.06x), and from in-domain programming languages (median 2.04x) to out-of-domain programming languages (median 3.10x).
Post II
will discuss out-of-distribution transfer in much more detail.
H-Nets are better on data that’s difficult to tokenize, in the sense of lacking a small vocabulary of reusable patterns. This is particularly evident in code, which is very dynamic and possesses a wide range of whitespace and symbols, syntax structure, and variable names (essentially an infinite vocabulary even over Latin characters!). Pre-defined tokens are less likely to capture the full range of semantics.
In
Part 3
, we show that H-Nets learn semantics on the fly at inference time, for example being able to learn variable names in code as one token; we hypothesize this is one particular mechanism that lets them excel at code.
Finally, we make the interesting observation that the H-Net’s improved performance on code is
not
due to spending additional compute.
Compression by data source
H-Net compresses more
H-Net compresses less
Figure 6.
Compression rates of the lowest-validation-loss H-Net at the largest FLOP budget, on every data source, relative to BPE. H-Net compresses almost every single code language more than the BPE baseline, indicating that it spends less compute despite modeling code much better.
Figure 6
supports our thesis that language modeling ability is not just about compute and parameters, but learning the right meaning from the data. By finding semantic chunks from raw bytes, H-Nets perform much better on difficult-to-tokenize domains while spending less compute.
Limitations of the H-Net ladder
Controlling H-Nets to match BPE-tokenized models in the way we did is actually seriously restrictive. Hierarchical networks have a tremendous degree of flexibility:
They can involve multiple stages of chunking, compared to a single static phase by BPE.
The compression rates are freely controllable; equating them to the ratio defined by BPE is actually against the spirit of H-Nets, which ideally should find
natural compression rates of the data
(loosely governed by information content and semantics of the data).
The hyperparameters of each network should be tunable; in fact, we’ve found that setting them equal to a BPE model is suboptimal.
Importantly, the H-Net ladder we defined by changing just the tokenization part of a BPE Transformer is
not an optimal H-Net architecture
at all. In fact, it can be viewed as being very favorable to the BPE Transformer baseline. What happens when we remove these restrictions?
Part 2: Training a larger H-Net
Data efficiency vs. SmolLM3
Byte H-Net
SmolLM3-3B (BPE Transformer)
Figure 7.
Byte-level 2-stage H-Net vs. SmolLM3 (compute and data matched) on pretraining evaluations.
We aimed to scale H-Nets up larger than the scaling ladders and the earlier versions (the first paper trained up to the equivalent of a 1.3B parameter model for 100B tokens). As a baseline, we chose
SmolLM3
, a 3B Transformer LLM released by Hugging Face with a fully documented training recipe. Because the SmolLM3 team released the model architecture, the training datamix, and several checkpoints throughout the training run, we were able to reproduce the recipe and compare the models throughout the training process - including past the horizon we trained to!
Data
: SmolLM3’s pretraining consisted of three phases with 8T/2T/1T tokens, using the Llama-3 tokenizer, for a total of 11.1T tokens. As our target horizon was much shorter, we used only the stage-1 data mixture. We made a best-effort reproduction built from the same public sources. Controlling for data is subtle; most training recipes report their data mixture as a fraction (e.g. SmolLM3’s is
73.2 / 12.1 / 12.0 / 2.7
for English web / multilingual / code / math), but this is usually in
tokens
. To try to control for data properly, we decided to match the underlying
byte-level
mixture (just as we did for the
scaling ladders
), which ended up being
76.5 / 10.9 / 10.3 / 2.2
.
Optimization
: We match the baseline identically without additional tuning for the H-Net: AdamW (0.9, 0.95), weight decay 0.1, clipping 1.0, peak LR 2e-4, same WSD schedule with 5B token-equivalents of warmup. We cooled down for the last 15% of training; one difference from the baseline is that SmolLM3’s cooldown phase appeared during its 3rd pretraining stage (after 10T tokens), with a different data mixture.
Architecture
: We built a two-stage hierarchical network over bytes.
The outermost (byte-level) stage uses four Mamba-2 layers in the encoder and four in the decoder.
The next stage adds a sliding-window attention block and four more Mamba-2 layers on each side.
The main network is a 40-layer Transformer with the same per-layer shape as SmolLM3, with global attention in every layer.
The compression ratios were set according to prior work (targeting 4x and 2x in the two outer encoder stages).
Where are the FLOPs spent?
Unlike the scaling ladders, we focused more on aligning with the philosophy of hierarchical networks: allowing the model to perform dynamic chunking in multiple stages, ideally following the semantics of the data. This made matching all axes to the baseline impossible, as parameters and compute get spent in very different ways. We aimed to control for
FLOPs/byte
, so that every minibatch of training sees the same underlying data and spends the same amount of compute as the baseline.
The compression ratios were set so the main network sees roughly one position for every 8 bytes (the trained model ends up at ~7.6×). Compared to ~4.5 bytes per Llama-3 token, this is about 40% fewer tokens than SmolLM3 processes on the same text.
That saving trades off for the outer encoder/decoder stages, which account for about 43% of the H-Net’s FLOPs (compared to 8% for the embedding and LM head in the tokenized Transformer).
The resulting models are compute matched to within 2% FLOPs/byte.
The H-Net’s total parameter count ended up at 3.67B, against 3.08B for the baseline. The difference is mostly the encoders and decoders plus the four extra main-stage layers; the byte embedding is tiny.
Parameters and FLOPs per component
H-Net vs. SmolLM3
Figure 8.
Parameters and (training) FLOPs/byte for H-Net and SmolLM3.
Results
We evaluated using benchmarks and the same evaluation suite as the official
SmolLM3 results
, among their set of “Reasoning & Commonsense” and “Knowledge & Understanding” evaluations.
Figure 7
shows both models’ benchmark scores over training. The H-Net reaches SmolLM3’s final average score after ~1T tokens compared to ~11T tokens. Since the two models are compute-matched per byte, the saving in training FLOPs is proportional.
Discussion: Data controls
Despite our effort to control for data and compute fairly, in hindsight we realized it’s still not obvious what a proper methodology should be. For example, let’s look at English vs. code: the reason SmolLM3’s token mix of
73.2% / 12.0%
respectively becomes
76.5% / 10.3%
at the byte level is because tokenizers compress English more (see
Figure 8b
), which itself is an artifact of BPE tokenization (it spends more effort compressing more frequently appearing data, so it’s tied to the arbitrary data distribution).
On the other hand, the philosophy of H-Nets is to compress data according to an “intrinsic” notion of compressibility and semantics. For example, we find that H-Nets compress code a lot more because code is naturally compressible; and we attribute much of H-Net’s
improvements on code
to this ability to understand the data better. But at the same time, this means that H-Nets spend
less compute
on code (because the same piece of code data gets turned into far fewer chunks sent into the main network) relative to the BPE baseline! So would a better way to control it be to let the models spend similar amounts of compute per source instead?
In short, BPE models and H-Nets can compress subdomains in opposite ways - for example, BPE compresses code less than English while H-Nets compress it more - so it’s impossible to both data- and compute- match, and the right way to compare models is subtle. These are all open research problems!

Visualizing H-Net’s dynamic tokens
We show an H-Net’s chunks for several examples (that it was not trained on) for every source of its data mixture. We also show various baselines including three BPE tokenizers:
the Llama-3 tokenizer (which SmolLM3 uses)
a new BPE tokenizer trained directly on the SmolLM3 training corpus, to show what BPE would learn completely in-distribution (
Corpus
)
an in-corpus BPE tokenizer with
no pretokenization
(
Corpus (NP)
), which we will cover more in the
next post
We also provide chunks of the originally published H-Net (denoted
LH-Net
) to illustrate qualitative improvements from our internal version.
Language
H-Net
Compare with:
Figure 10a.
Natural-language text chunked by H-Net (left) and tokenized by various BPE methods (right). Pick a language and an example; H-Net can display stage-1 chunks (the default) or its finer-grained stage-0 chunks. Hovering a byte shows its chunk, the router’s boundary probability p, and the BPE token it falls in.
H-Net presents coherent and semantically meaningful boundaries for natural languages including Latin-based/Germanic languages that use spaces as delimiters, as well as multi-byte character languages (e.g. CJK, Hindi) with and without explicit delimiters.
H-Net merges multiple words into a single chunk that can be naturally grouped together. For example, “a foot”, “quite a few”.
Interestingly, tokens from the BPE tokenizer without pretokenization also often comprise multiple words. However, they exhibit many weird boundaries, such as
beat a bear
being separated into
be
at a
bear
.
H-Net boundaries are not pattern-based. Rather, they are context-based. For example, while “a” frequently gets merged with the following noun in English,
a
less frequently is grouped with other words in Italian as it has different meanings.
For all languages, H-Net achieves much higher compression than BPE tokenizers. This is more pronounced in certain languages that require many bytes to form a character such as Hindi.
Code
H-Net
Compare with:
Figure 10b.
Coding examples chunked by H-Net (left) and tokenized by various BPE methods (right). Pick a language and an example; H-Net can display stage-1 chunks (the default) or its finer-grained stage-0 chunks. Hovering a byte shows its chunk, the router’s boundary probability p, and the BPE token it falls in.
Figure 10b
shows examples from programming languages.
H-Net boundaries for coding languages also exhibit interesting characteristics derived from their context-based properties. For instance, BPE tokenizers strictly use newline as a boundary, whereas H-Nets accept multi-{space/tab/newline} chunks (example:
__init__(\n self,
).
H-Nets can generally compress code far more than BPE (also see discussion for
Figure 8b
).
H-Nets can benefit from
in-context tokenization
to recognize repeated motifs such as new variable/function names as they keep recurring.
Aside: How does this compare to the original H-Net?
Since we published the concept of
hierarchical networks
in 2025, we’ve made many significant improvements to the core architecture and learning mechanisms. We plan to release some of these architectures to the community over time. Here we discuss some concrete qualitative areas of improvement.
For the purposes of this comparison, we’ll call the earlier model the
LH-Net
, where L can be thought of as meaning “lazy” or “lookahead”. In brief, this original model aims to draw chunk boundaries only after it sees the start of the next chunk.
2
This allows LH-Net to have more context in creating chunks, but turns out to negatively impact its ability to perform next-token (byte) prediction as well as model multiple hierarchies.
Qualitative differences between LH-Net and our current internal H-Net can especially be seen when examining recursive hierarchical networks with multiple stages.
In English, consider the first example.
Stage 0 chunks from H-Net are generally more meaningful than LH-Net’s. For example, when they occur in the middle of English words, they generally align better with linguistically meaningful stems.

In scripts where characters are represented with multiple bytes, such as CJK (Chinese, Japanese, Korean), a multistage LH-Net doesn’t segment characters correctly, even after both stages of chunking.
New emergent behaviors: in-context tokenization
In-context tokenization
An H-Net’s tokenization not only changes over training time, but can also evolve during inference, which we call
in-context tokenization
. We previously discussed some simple cases of how boundaries of H-Nets are context-based, and not pattern-based. In
Figure 11
, we highlight four interesting examples of the in-context tokenization:
New concepts
: When an H-Net encounters an unfamiliar word or a new concept, it tends to split the word into multiple chunks (similar to how BPE would read unfamiliar strings). As it encounters the same word multiple times, it progressively learns to group the word into fewer chunks.
Repeated formats
: If there is a repeating phrase, we can easily expect what would come next. Similarly, in such a scenario, H-Nets learn to further compress inputs, drawing very large chunks to conserve compute.
Recurring motifs
: As shown in the figure, H-Nets learn to discover implicit patterns in inputs. In the letter blocks example, the recurring blocks –
LURD
,
WHYV
, and
FYB
– get grouped together. The digit blocks example is an interesting case that shows how an H-Net can discover the repeated motifs (
2526
,
3987
, and
3526
) underlying the data. The behavior of stage 0 vs. stage 1 is also interesting to observe.
H-Net
Compare with:
Figure 11.
In-context tokenization: made-up words that recur in a paragraph, lines that repeat one format, and runs of repeating letter and digit blocks.
Out-of-domain Programming Languages
Finally, we visualize how H-Nets handle programming languages that they haven’t seen. We saw
previously
that the H-Net ladder was particularly effective (relative to the baseline) for out-of-domain programming languages.
Figure 12
shows examples from these 10 programming languages.

Part 4: From tokens to atoms: hierarchical networks beyond language
This post has so far focused on the capabilities of hierarchical networks as applied to language modeling on bytes, which captures the ideal of learning from raw data in the context of language.
We believe that the utility of H-Nets goes far beyond language: the
core concept of chunking low-level data into higher-level patterns is fundamental to intelligence
, and can be applied to any domain.
One such area is audio, a core focus of Cartesia, where the inability of models to autonomously abstract raw audio into phonemes and words represents a major bottleneck toward multimodal speech-to-speech models (and in fact was a motivation for us to start investigating H-Nets years ago!).
More broadly, bytes are not necessarily a universal encoding for all domains. Most domains have a concept of “primitive building blocks”, such as characters or bytes for language, pixels for images and video, waveforms for audio, nucleotides for biology, and so on. We’ve started thinking of different modalities as being built from various base
atoms
, and of so-called
atomic models
as the truly bitter-lesson-pilled way to build powerful foundation models for multimodality. We highlight some examples of additional domains.
Biology (DNA)
DNA is the lowest-level programming language of biology. Depending on the context, its natural level of abstraction, and therefore its natural primitive units, changes drastically. Because of this, we hypothesized that H-Net’s dynamic tokenization would be significantly more effective than a static tokenization scheme on the DNA domain.

We compare an H-Net and a Transformer on autoregressive modeling of DNA sequences. Both models operate at the nucleotide resolution as input (so the vocabulary size is 4, plus some special token IDs). The H-Net has a target compression ratio of 6×: its main network sees approximately one chunk for each six nucleotides.
We fit compute-optimal scaling ladders using a similar procedure as in Part 1. The H-Net leads to a 6–7× compute gain on all three sets.

Qualitative analysis in DNA: Biology’s context-dependent atomics
H-Net was trained only on the next-letter prediction task for prokaryote (bacterial and archaeal) genomes, so the adherence of H-Net’s token segmentation to biology’s natural structure in the human genome is purely emergent behavior. Here we display some of these examples:

Histones are the proteins that DNA wraps around. This example window runs from the gene's promoter (non-coding region), through its 126 codons (coding), and to the hairpin at which the RNA terminates (non-coding region). Within the coding region, the unit is the codon. H-Net learns chunks that start on codon borders and almost all run one to three codons long
. The non-coding DNA on either side (the promoter region before and the termination signal after) has far less structure and is not read in threes. There the H-Net draws chunks that are long and less structured
.
Quick primer on Biology/DNA
DNA and genes. DNA is a string of four letters: A, C, G, and T. A gene is the stretch of DNA responsible for producing an RNA sequence, which is usually translated into a protein. Only its coding region actually spells out the protein, while the DNA around it is far less constrained and more information-sparse: the promoter region before it, the signal that ends the RNA after it. They control when and how the protein is made, not what it is. Additionally, in human genes, introns, non-coding regions that sit in the middle of the coding region, are spliced out and also do not contribute to the protein sequence.
Codons and the reading frame. The coding region is read three letters at a time, from a start codon (usually ATG) to a stop codon (TAA, TAG, or TGA). Each three-letter codon names one amino acid in a protein sequence. Where reading starts sets the reading frame: shift it by one letter and every codon downstream changes.
Some notable learned behaviors:
Inside a gene, the H-Net router settles on a different atomic unit depending on what it is reading; we see biologically aligned treatments of:
coding region vs. non-coding
regions
exons vs. introns
Robustness: H-Net’s learned codon
grid isn’t fixed; where two coding regions overlap and the second is offset,
H-Net’s boundaries adapt quickly
In a transfer RNA (tRNA) gene, the
natural unit shrinks to a single letter. H-Net boundaries learn to adhere to
this new natural unit
Large sections of repeats in DNA
are typically information-sparse, so in a repeat, the natural biological unit
grows to the whole repeat
Interestingly, as one may
expect, a lot of these biologically adherent behaviors aren’t learned until late
into training, as shown through the learning trajectory animation. The late
onset of these behaviors highlights the nontriviality of the “tokenization task”
in the DNA domain, and supports the thesis that
hand-crafted tokenization
schemes would be even more difficult and less effective in multimodal domains
than in language
.
Vision
Hierarchical networks are naturally defined for one-dimensional sequential data, where chunking and segmentation are intuitive. Extending them to higher-dimensional modalities, however, presents a significant technical challenge – and simultaneously a great opportunity, as vision is a domain naturally suited to hierarchies. In ongoing research, we’ve developed new techniques to apply H-Nets to N-dimensional data such as images and videos. When integrated into a pixel-space diffusion model, H-Nets not only improve generation quality, but also uncover unsupervised semantic concepts directly from raw data – mirroring the emergent behaviors
we saw with language
.
In more detail, we take a standard pixel-space flow-matching baseline
JiT
, and replace its backbone with a multi-dimensional H-Net. Just as with 1D H-Nets, the model learns both where to chunk and how much to compress. This allows it to dynamically reallocate compute across three axes:
spatially
(focusing on detailed regions over simple ones),
integration time
(varying effort by denoising step), and
samples
(allocating more compute on complex images). Consequently, the model consolidates homogeneous or low-information areas and focuses on salient details, and discovers semantic segmentations of the image completely without supervision. A final interesting detail is that unlike existing token-merging methods that rely on the similarity of contiguous patches, our 2D H-Net doesn’t enforce local grouping. Because of this, the model often appears to infer underlying 3D structure from flat 2D projections. For instance, it routinely groups disjointed background regions into a single coherent chunk, even when they are separated in the image by occluding foreground objects.

In the
next post
, we dig into the compute efficiency results in much more detail. We study
loss-to-loss
scaling laws and find empirical evidence that H-Net’s improved performance really does come from its ability to learn from raw bytes end-to-end.

Since our focus is tokenization, other improvements (gated attention, MoE, hybrid state space model/linear attention layers) are orthogonal, and internally we’ve found that H-Nets synergize with them.

Spiders Spin 'Silk Dope' into Nature's Toughest Material
By probing its molecular structure, biologists are uncovering how a tangle of unstructured proteins turns into a strong, flexible fiber.
Introduction
A spider, when knocked off a wall, doesn’t fall for long. Within milliseconds, it spins a soup of proteins into sturdy climbing gear. Using a thin, shimmering strand of silk, the spider hauls itself back up.
The strand is tougher than Kevlar, the synthetic fiber in bike tires and bulletproof vests, and stronger than steel. It’s flexible and biocompatible with human bodies. Scientists dream of making spider silk into high-performing materials for seat belts, helmets, naval materials, and even scaffolds to help repair brain cells. But attempts to make spider silk in the lab have fallen short because researchers don’t know enough about how a spider spins “silk dope,” a liquid blend of proteins, water, and salt, from its silk glands into a remarkable solid.
Mapping out the molecular mechanisms behind the process is “really the holy grail” for the field, said
Gregory Holland
, a chemist and spectroscopist at San Diego State University. Recently, he led research that described how the molecules in liquid spider dope reorganize into semiliquid droplets called condensates before turning into solid silk fiber. The result is
an atomic-level look
into the spider’s silk factory.
The findings are also a practical guide to the formation of condensates, which nature has used repeatedly to organize molecules for genetic processes and for the creation of impressively strong biological materials.
“It’s becoming clear that [condensates are] a common strategy that’s being used across a range of different organisms,” said
Matthew Harrington
, a biological materials scientist at McGill University who was not involved in the study. By unpacking how nature uses condensates, scientists hope to re-create some of its most rugged materials.
Silk Factory
Spiders are incredible natural factories. They can spin up to seven types of silks, and the same spider can often spin several of them. Aciniform silk wraps up insects for later snacking. Rubbery flagelliform silk reinforces the capture spiral to absorb shock. Dragline silk anchors webs and spiders to walls. Each type of silk has different properties depending on the species and related to how its molecules are assembled. And silks of the same type can have slightly different properties depending on the species.
In 1907, scientists discovered that spider silk is made of long, modular proteins, later named spidroins, which are in the same group of fiber proteins as collagen and keratin. More than half a century later, X-rays started to reveal the fiber’s underlying structure. The silk is made of flat sheets of protein, known as
beta sheets
, that are embedded in a less ordered, non-crystalline matrix.
In the early 2000s, as they inspected the spidroins in solution, researchers didn’t see organized, fixed structures like those seen in most proteins. Instead, the spidroins featured intrinsically disordered regions that fluttered around, forming and re-forming various shapes. Researchers then started to untangle how this soup of unstructured proteins could organize into strong, solid fibers.
One early theory suggested that proteins in the dope start to align with one another, as in a crystal, while remaining dynamic, in a transitional state known as “liquid crystal.” Another considered spider silk to be like silkworm silk, which has proteins organized into micelles, or small spheres, which then compress into silk fiber.
Then, in 2007, researchers noted that spidroins engineered in the lab formed liquidlike globs. Soon these kinds of structures would become inescapable in modern biology. In 2009, scientists at the Marine Biological Laboratory in Massachusetts and the Max Planck Institute in Germany discovered
droplets of aggregated RNA molecules
in fertilized worm eggs. These were condensates — liquid- or gel-like bubbles of concentrated proteins suspended in solution. Though observed for more than a century, condensates started to be seen as a critical organizational tool for molecular processes across life.
The researchers realized that condensates concentrate molecules, pre-organizing them into a flexible microenvironment without locking them in place like a solid. “Because they’re fluid, they’re malleable,” Harrington said, “so you [i.e., biology] can kind of shape them into whatever you want.”
More research showed that living cells use condensates everywhere, to organize DNA, regulate gene expression, and package proteins. At a macro scale, they help species build interesting materials. They help mold squid beaks into a gradient of stiff parts. They form strong adhesives that allow mussels to attach themselves to rocks, and marine cement that sandcastle worms use to build protective tubes.
“It’s been a hot area in biology,” Holland said.
Though researchers had described condensate-like blobs forming in lab-made spidroins more than a decade earlier, they weren’t thought of as condensates until 2020, when
Keiji Numata
, a biomaterials chemist at Kyoto University, suggested that spider silk
undergoes a condensate phase
during its transition from liquid dope to solid thread.
Condensates form by “liquid-liquid phase separation,” a process through which molecules in a liquid can start to interact weakly with one another, easily forming bonds and breaking them, as a result of a stimulus such as a change in pH, chemicals, or temperature. Numata proposed that phosphate in the ampulla, the middle section of a spider’s silk glands, might initiate these interactions. But no one had described the atomic-scale mechanisms that drive their formation until
Hannah Johnson
, then a graduate student in Holland’s lab, decided to take a look.
Inside a Black Widow
Every few months throughout 2023 and 2024, a package of female black widow spiders arrived at the San Diego State University chemistry department. The arachnids, jet black with a dash of red, cultivate a powerful venom that can be painful to humans. Except for that minor inconvenience, they make good subjects for studying spider silk. Their dragline silk spidroin proteins are some of the best-characterized in all spiders. And they’re available year-round, unlike some spiders that spin their webs seasonally.
To catch prey, black widows (top) lay a mess of sticky strands that acts as a trip wire. To collect silk for experiments, scientists gently reeled in strands from the spiders’ spinnerets (bottom).

Six times over the course of two weeks, Johnson donned two pairs of protective gloves. Over the course of an hour, she and several students “silked” black widow spiders, which had been knocked unconscious by carbon dioxide. With tweezers, the scientists gently pulled the strand of silk from the spider’s spinnerets — the abdominal spigots that fibers emerge from — and reeled it in by winding it around a vial with a spinning motor.
“The spiders who give a ton of silk are our favorites,” Johnson said, “but I have a soft spot for the rebels who don’t want to cooperate.” Throughout the process, the researchers fed the black widows a cocktail of amino acids (like “protein shakes,” Johnson said) enriched with particular isotopes that they could detect in the lab.
Nuclear magnetic resonance (NMR) spectroscopy can map the structure of a molecule. It sends out radio frequencies to disturb the nuclei inside atoms, which then move in a way characteristic of the type of atom. Johnson used NMR on the liquid spider dope, as well as on condensates collected from the spiders’ ampullae. Meanwhile
Kevin Chalek
, then a postdoctoral researcher in Holland’s lab (now a researcher at the University of California, Los Angeles), mapped the atomic structure of the proteins in the solid fiber.
“We were trying to bridge the gap between what is happening when the protein is inside the spider and when it’s outside the spider,” Chalek said. “These are the same protein, [so] how can they be so different? And what exactly is happening between the two?”
Johnson observed that after she added phosphate to the liquid silk dope to start the condensation process, side groups on two amino acids (arginine and tyrosine) in the intrinsically disordered regions of the spidroin proteins started to interact weakly with one another. This interaction displaced water, organizing the disordered proteins into a denser, gel-like material — a condensate. The interaction persisted in the solid fiber, suggesting that the amino acids serve as “molecular stickers” that guide the disordered proteins into condensates and ultimately into fibers.

Others on the team used AlphaFold, an artificial intelligence tool that
models protein structures
, and molecular dynamics software to predict this process computationally. Researchers know that spider silk’s strength comes from the sturdy
beta-sheet protein structures
in its final fiber. The team’s simulations showed that these amino acids line up right up at the bends in the beta sheets, suggesting that they are helping to guide the spindroins into their final structure.
“Understanding how those side groups interact and how they can develop structure that’s greater than the sum of its individual parts … is fantastic,” said
Chris Holland
, a biologist at the University of Sheffield who was not involved in the study and is not related to Gregory Holland. And they used real spiders, instead of synthetic silks, “which is brilliant.”
Their findings are “direct evidence” that condensates can form from native silk, which is “quite significant,” said
Daiwen Yang
, a biologist at the National University of Singapore who was not part of the study.
Their description of condensates doesn’t rule out earlier theories of spider silk formation. Gregory Holland, who had previously shown the presence of
micelles in native spider silk
, suggested that all three — micelles, condensates, and liquid crystals — could be stages of the same phase transition. Micelles that form in the liquid dope prevent the messy, disordered proteins from clumping and getting tangled. The proteins can also pre-assemble into condensates, or align into structures like liquid crystals before they are released from spinnerets as highly ordered fibers. But the actual process is likely “more dynamic and heterogenous” than sequential, Gregory Holland said, with several of these structures forming in the mixture at the same time.
Harrington agreed. “I don’t think these are mutually exclusive,” he said. “You might have different sorts of phase transitions that are occurring at different stages of the processing.”
Still, there’s more to understand about how these interactions add up on this factory line. There are likely other significant amino acid interactions that the researchers haven’t yet been able to map out in detail. They also want to look for triggers that initiate the process beyond phosphate. “There could be a range of other things that are driving structural changes in these proteins,” Chris Holland said. “We don’t know all of the switches yet.”
Superior Materials
Describing the entirety of the intricate silk-spinning process will take a lot of effort, but the payoff could be huge. Spiders produce small amounts of usable silk compared to silkworms, which have been reared for their cocoons for more than 4,000 years. It takes thousands of silkworms to make a silk shirt; it would take
around 1 million spiders
, in part because they don’t produce cocoons that can be easily processed. There is a more practical reason: Their cannibalistic nature makes them difficult to keep because each spider needs its own container.
Producing spider silk in the lab could result in a new range of strong yet flexible materials. Kevlar, a synthetic fiber, is currently our toughest material, but it requires processing at very high temperatures and acidic conditions. “Here, you have an organism like a spider or a mussel,” Harrington said, “which is basically making a superior material under ambient conditions in seawater or in just plain air.”
Humans haven’t figured out how to match those organisms yet. When scientists synthesize spider silk in the lab, using the exact sequence of amino acids to build a spidroin protein, the resulting silk is not as strong as natural silk. “Something is happening there that we’re also struggling to mimic,” Chalek said. He thinks additional strength must be provided by something beyond the protein’s beta sheets, arising from other aspects of silk’s structure, or perhaps from parts of the spidroin protein frequently left out of synthetic silk solutions.
“I think once we really understand those blueprints,” Chris Holland said, “we’ll be able to do more stuff with silk.”

I've always had a fascination with reverse-engineering browser fingerprinting scripts. Most of my time has been spent looking at the usual suspects (popular fingerprinting libraries like FingerprintJS and more sophisticated scripts used by anti-bots like Cloudflare Turnstile, Akamai, and others).
At some point, I wanted to know what else was out there. I had an idea: What if I crawled the web and intercepted fingerprinting-related browser API calls and mapped it all?
To do this, I used the
Tranco Top Sites list
and began crawling using Playwright. I would hook canvas
toDataURL
calls and common fingerprinting/anti-bot properties like
navigator.webdriver
to filter out benign canvases.
For those unfamiliar, canvas fingerprinting generally involves drawing text, shapes, or other graphics onto an HTML
<canvas>
and extracting the resulting pixel data. Subtle differences in how browsers, operating systems, graphics drivers, and hardware render those graphics can help distinguish one browser environment from another.
Most implementations are pretty boring to look at. A few shapes, some colored rectangles, and the occasional pangram. After crawling 10,000 websites, I had accumulated a surprisingly diverse collection of canvases.
I decided to put them all in one place:
fingerprint.garden
. As I looked through the results, I recognized some familiar faces. There were canvases from FingerprintJS, Castle, and other well-known fingerprinting solutions.
There were also quite a few I didn't recognize.
Some were incredibly simple. Others were surprisingly elaborate. And a handful were, in my opinion, works of art.
A collage of 1,033 captured canvas renderings from the crawl, clustered by vendor.
I set out to find my favorite.
A work of art
One canvas in particular caught my eye. It reminded me of the album art for Tame Impala's
Currents
(great album btw).

I wanted to know which script was responsible for this lovely canvas.
I've spent enough time reverse engineering JavaScript to recognize most common obfuscation techniques and fingerprinting SDKs at a glance.
I wasn't expecting anything unusual. Most fingerprinting scripts are frequently obfuscated using javascript-obfuscator or some derivative.
The responsible script was

A peek inside
Scanning the file with my eyes, everything seems standard so far...

mangled function name, okay...
function calculateDeadlyLethalSuicideAspirinDosage
This was all pretty alarming until I asked myself, could this be some form of anti-LLM obfuscation? It would make sense: include symbol names that would intentionally trip model safeguards to prevent deobfuscation.
I had Astra take a look at the script, giving it the context that this script seems to intentionally set misleading variable names to intentionally prevent LLM-assisted deobfuscation attempts.
Astra refusing to deobfuscate the script, citing safety risks around biological research.
Maybe unsurprisingly, Astra was not willing to comply with the request.
I also attempted this using the Daybreak Blue toggle with the same result, blocked.
Out of curiosity, I tried GLM-5.3 with the same prompt and it complied!
Inside the script
I was mostly curious what this string of invisible unicode characters represented.

The failing war with Iran marks a dramatic retreat by the U.S. from the Middle East.
The post The Incredible Shrinking Superpower appeared first on The Intercept....
The failure of Tel Aviv and Washington to achieve their war aims in Iran has resulted in the most dramatic American retreat from a region since the U.S. flight from Vietnam in 1975. This startling American defeat — after a generation of forever war failures and stalemates — has been thrown into broad relief by the resumption of another regional conflict that has received far less attention than the Trump administration’s sputtering war with Tehran. This fall, the forces that most Americans know as “the Houthis” have conducted a blitzkrieg in their native Yemen and have been pummeling Saudi Arabia’s aviation and energy infrastructure with missiles and drones. In doing so, they have put a spotlight on the limits of American power, and the shrinking U.S. military footprint, in the Middle East.
The long-standing conflict between Saudi Arabia and northern Yemen’s Ansarullah, or “Helpers of God,” led by the Houthi clan, heated up again in July 2026, when Saudi Arabia
struck
Sanaa International Airport to prevent a Houthi delegation from landing on its return from the funeral in Iran for slain Ayatollah Ali Khamenei. The Ansarullah government launched its own attacks and, in October, managed briefly to close Saudi Arabia’s own airport. The renewed war has now expanded into a regional conflict, with Pakistan, Türkiye, and, recently, Egypt pledging to defend the kingdom from attack, though none of these regional powers appear eager to conduct operations in Yemen itself. Notably absent from the current conflict is Saudi Arabia’s most powerful ally, the United States, since President Donald Trump has repeatedly declined to intervene on behalf of his Saudi allies.
The typical U.S. press framing of Ansarullah as an “Iran-backed militia” is inaccurate, since the movement has local, Arab nationalist reasons for its actions and is a full-scale government that rules some 80 percent of Yemen’s population. Still, it does receive surreptitious technical and military support from Iran, though nothing like the hundreds of billions of dollars’ worth of high-tech armaments — from kits turning 2,000-pound “dumb” bombs into
precision munitions
to advanced
air-to-air missiles
— that the U.S.
provides
the Saudis. Ironically, Trump’s war on Iran, fought in
conjunction with
Israeli Prime Minister Benjamin Netanyahu, weakened the Saudis and exposed their vulnerabilities to military attack by Iranian drones and missiles, impelling them to seek a symbolic win over a less formidable enemy in neighboring Yemen. But the weaknesses
exposed by Iran’s drones
helped encourage a vigorous Ansarullah rejoinder.
The Incredible Shrinking Superpower
The American refusal to join Saudi Arabia’s war signals a profound degradation in U.S. capabilities and standing in the Middle East. The U.S. military had, for decades, dominated the region
from a network
of about 20 major bases. The U.S. Navy operated out of the headquarters of the Fifth Fleet in Manama, Bahrain. The U.S. Air Force flew missions from the massive al-Udeid Air Base in Qatar, which housed 10,000 U.S. personnel. Thousands of ground troops were barracked in Kuwait, the United Arab Emirates, and Jordan. The Pentagon
admitted
that “Iranian strikes damaged and destroyed hundreds of buildings and structures at U.S. bases in Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan during the conflict. In addition, dozens of U.S. aircraft were destroyed or damaged during OEF.”
The naval base at Manama, one of America’s most important naval facilities and headquarters of the Navy’s Fifth Fleet, was destroyed by Iranian strikes. (Acting Navy Secretary Hung Cao
admitted
last month that Iran “blew the hell out of Bahrain.”) The loss of Manama led to supply shortages and
poor morale
aboard the USS Lincoln and other ships patrolling the Strait of Hormuz, bedeviling Secretary of Defense Pete Hegseth.
The CIA offices at the U.S. Embassy in Riyadh were
annihilated
. Iran struck al-Udeid’s evacuated Combined Air Operations Center in Qatar, from which the Pentagon had directed its strikes on enemies as diverse as the Taliban and ISIL over recent decades, and rendered this facility
inoperable
. All U.S. troops were also
withdrawn
from Iraq, a process accelerated by the inability of U.S. missile interceptors to protect them from attacks by Iran and allied Shiite militias there.
Iran’s deployment of swarms of Shahed drones caused the United States and Israel to use up much of their
stock of interceptors
, which are time-consuming and expensive to replace. A basic
Shahed
costs as little as $20,000, though new hardened versions are more expensive — whereas a
Patriot interceptor
costs $4 million. One reason the Trump administration may be reluctant to intervene in Yemen is that if the U.S. cannot fly missions from al-Udeid, and cannot be sure any new fighter-jet fleets stationed in the region will be safe from Iran, given the paucity of interceptors, the Pentagon will have a limited ability to rescue any U.S. pilots shot down over Yemen.
America’s Profound Weakness in the Middle East
Saudi Arabia launched a war against the ascendant Ansarullah in 2015 when the latter staged a coup in the capital of Sanaa. The Ansarullah movement is rooted in Yemen’s Zaidi Shiism, though it is more radical than traditional Zaidism. (Zaidi Shiism differs substantially from Iranian Shiism, having no ayatollahs and having relatively good relations with Sunnis.)
About a third of Yemenis are Zaidis, who predominate in the
north
of the country, and many have long resented the dominance of their politics and culture by neighboring, oil-rich, Sunni Saudi Arabia, whose official ideology is hard-line Wahhabism, a puritanical form of Islam that insists on a literal interpretation of the Quran. Wahhabi proselytizing among the Shia enraged the Houthi clan and their followers began rebelling against the government of military dictator Ali Abdullah Saleh in 2004. But when he was deposed by popular demonstrations during the Arab Spring in 2012, Saleh gradually allied with the Houthis, and by 2015 about half the Yemeni military rallied to their side, along with some major Sunni tribes.
In response to the Houthis’ rise, a Saudi-led coalition that included the United Arab Emirates began bombing Yemen in 2015. Until 2022, the U.S, then militarily dominant in the region, provided the Saudis with strategic advice, weaponry, and in-air
refueling for their fighter jets
in the Yemen war, though Riyadh’s tendency to
bomb civilian infrastructure
rather than confining themselves to military targets caused tension between the two allies. While the Saudis and their coalition pushed the Houthis out of much of the south of the country, including Aden, they were unable to dislodge them from the north. The Saudis implicitly acknowledged their failure with a United Nations-brokered truce in
April 2022
, which largely held until this past summer.
The
Forever Wars
Effect
America’s forever wars against Middle Eastern countries that decline to accept the Israel project or American corporate neocolonialism helped reignite the Saudi–Yemeni conflict. Iran is the last major state in the region that rejects Israel and is off-limits to U.S. corporate investment, a stance that inspires much of Washington’s animus. Netanyahu was therefore
easily able
to
persuade
Trump, as a privileged visitor to the White House Situation Room, to attack Iran in February.
The glib expectation of Netanyahu and of his
Mossad
chief at that time, David Barnea, that the Islamic Republic would crumble if Israel
murdered
Ayatollah Ali Khamenei and around 50 other high-ranking regime figures proved
wishful thinking
. The notion that Iran was vulnerable to a tightened petroleum blockade was turned on its head by the hard-liners who ascended to power after Khamenei’s death. Largely veterans of the grueling eight-year Iran–Iraq War of the 1980s, the country’s new leaders pursued a policy of “de-basing” toward the United States, taking out its main regional military facilities.
By successfully striking Saudi Arabia, Iran demonstrated that the kingdom’s ability to protect itself is imperfect and its infrastructure is vulnerable.
In addition, Iran launched precision
strikes
at the energy facilities of their Arab Gulf neighbors who had hosted those American bases. They struck Kuwait’s national petroleum company and its fields and refineries. They took out 17 percent of the production of Qatar’s Ras Laffan natural gas facility, even though Doha had good relations with Tehran and had mediated for Iran. Tehran also struck ships passing through the Strait of Hormuz, using missiles and drones, scaring the major shipping insurers into withdrawing their contracts. Few shipping magnates would risk cargoes worth billions of dollars without insurance.
Iran
threw the world
into an
energy crisis
reminiscent of the 1970s, which would have been even more devastating had China not released oil from its vast private and public petroleum reserves and
cut
its oil imports from 11.5 million barrels a day to under 9 million barrels a day, a move partially enabled by its turn to electric vehicles, which
saved
it 1.5 million barrels a day. High gasoline and diesel prices hurt Asia more than the United States, but prices rose globally. A third of the world’s helium, essential for cooling computer chips in the production process, comes from the Gulf, and that supply was also interrupted, increasing the price of electronics.
By successfully striking Saudi Arabia, Iran demonstrated that the kingdom’s ability to protect itself is imperfect and its infrastructure is vulnerable. By
blockading the Strait of Hormuz
in a way that the United States had difficulty undoing, Iran demonstrated the vulnerability of key world maritime arteries, something Ansarullah had already highlighted by striking at
shipping in the Red Sea
to protest the Gaza genocide.
Blockade for Blockade
When the Saudis bombed Sanaa’s airport in July 2026, Ansarullah’s leadership appears to have decided that Riyadh posed an ongoing existential danger to their state and sought to
strangle
the Yemeni economy,
just as Israel had done to Gaza
. Moreover, they sensed that the kingdom could be rolled back in the wake of the failure of the Israeli–U.S. war on Iran. Just as Iran had weakened the Gulf Arab states with its blockade of the Strait of Hormuz, the Houthis believed they could seriously degrade the Saudi economy by blocking Riyadh’s shipping through the Bab al-Mandab, “the Strait of Tears,” between the Red Sea and the Gulf of Aden.
Saudi exports through the Strait of Hormuz had fallen substantially. The kingdom did, however, have an escape valve: its East-West pipeline to Yanbu on the Red Sea. Ships loading at Yanbu then headed for Saudi Arabia’s major Asian markets through the Bab al-Mandab. If Ansarullah could make the tanker captains fearful of this transit, they could reduce Saudi Arabia’s income even further. The Houthi spokesperson, Muhammad Abd al-Salam, warned that the prohibition of Saudi shipping was only the first step in a tit-for-tat strategy of “blockade for blockade.” The idea wasn’t original. The Saudis and the U.S. had often attempted to blockade petroleum imports to northern Yemen during the seven-year Saudi–Yemeni War.
In the subsequent three months, Ansarullah deployed missiles and drones constructed from Iranian models by military engineers trained by the old nationalist government of Ali Abdullah Saleh, many of whom had joined the Ansarullah military, in what has been called a Yemeni “
military industrial complex
.”
Just as the kingdom’s interceptors had proven unable to prevent Iranian strikes on targets such as the CIA section of the U.S. Embassy in Riyadh, they sometimes failed to halt the barrage of Yemeni missiles and drones. Refineries and oil installations, even the headquarters of the state oil giant, Saudi Aramco, in Dhahran, were
hit.
In October, Ansarullah closed Riyadh’s International Airport, just as the Saudis had attempted to close that of Sanaa in July. Ansarullah also surged out of their mountain strongholds and made a major push to Yemen’s southwest coast, taking the strategic port of Mocha overlooking the Bab al-Mandab. They also
moved on Taiz
, an inland industrial city of nearly 1 million inhabitants, one of the last major population centers not already under their control, in a campaign that tested the ability of the small Saudi-backed government of Rashad al-Alimi in Aden to resist it.
Highlanders and Oil Sheikhs
Just as the Vietnam War was one conflict among many fought in the Third World during the Cold War between the U.S. and the Soviet Union, so the Saudi–Yemeni War of 2026 is part of the larger struggle between the U.S. and Israel and Iran. Still, just as Vietnam was more about Vietnamese anticolonialism, nationalism, and sovereignty than about Communism and the ownership of the means of production, so the Saudi–Yemeni War is about Yemeni autonomy more than it is about the loose Houthi alliance with Iran. The conflict is not primarily between Zaidism and Wahhabism, though religious tensions are part of the story, but is far more rooted in a struggle between desperately poor Yemeni highlanders and fabulously wealthy Saudi sheikhs.
The plutocratic Saudi ruling elite is closely tied to Washington and has secret dealings with the Israelis, with whom it shares a distrust of the poverty-stricken Palestinian resistance, and views Ansarullah as cat’s paws of Iran in the Arabian Peninsula and as radical republicans trying to overthrow the region’s oil monarchies in favor of populism. For its part, Ansarullah are Arab nationalists, anti-American, and seek to use oil resources for
populist
purposes. And they have been willing to attack Israel to defend the Palestinians of Gaza from genocide.
Last week, Ansarullah battered targets across Saudi Arabia, prompting a further pullback from the region by Washington. The Yemeni forces attacked King Fahd International Airport in Dammam. An Ansarullah spokesperson said the group also targeted the Saudi defense ministry in the capital, Riyadh, along with an Aramco site in Yanbu, and an airport in the southern city of Abha. Reports also emerged of an attack on another Aramco oil field.
“Houthis have increasingly engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure,” wrote State Department spokesperson Tommy Pigott in an October 21 post on X, after the wave of attacks, ordering “non-emergency U.S. government employees and their family members” out of Saudi Arabia.
It’s just the latest evidence of the most significant regional retreat by the U.S. in half a century and evidence of profound American military decline. The outcome of their war with the Saudis will not determine the issue of the U.S.–Israeli contest with Iran, but the very ability of Ansarullah to prosecute it points to the profound weakening of the American posture in the Middle East.

Today, we’re announcing the next frontier model: Gemini 4 Carbon, our strongest model with state-of-the-art cybersecurity and long horizon capabilities.
Carbon ranks #1 on the recently updated v5.0 of
Artificial Analysis Intelligence Index
at 59. It shows significant gains across coding and agentic tasks as well as across key capabilities critical for cybersecurity defense, landing a firm lead in SEC-bench Pro (88.2%) for finding vulnerabilities, ExploitGym (54.8%) for exploitation, and CWE-bench (71.0%) for patching. On internal benchmarks, Carbon drives a strong uplift in generating secure code, and in live coding environments with our own teams it shows reduced misalignment and fabrication rates.
Building on
Gemini 4 Argon
, which was launched two weeks ago, Carbon illustrates the pace at which we’re pushing the frontier forward. Our researchers and models are working hand in hand to advance capabilities faster, while strengthening our safeguards in tandem.
We're taking a deliberate approach to rollout and are actively engaged in the U.S. government’s voluntary process for pre-release model testing. Starting this week, we will make Carbon available to a subset of cyber defenders and will gradually phase access to additional trusted partners through our
Fairwind Program
. We’re continuing to gather feedback and iterate on guardrails before making Carbon available to developers, businesses, and consumers via our product surfaces as soon as possible.
Gemini 4 Carbon will launch at the same introductory price
1
as Argon at $2 per million input tokens and $10 per million output tokens, with cached input tokens priced at 95% off input token price.
Improving coding and reasoning for challenging, long-horizon tasks
Designed to take on much harder, long-horizon engineering problems, Carbon is built for sustained agentic workflows. Internally, our teams have seen Carbon run for days to persist through dead ends to tackle complex, multi-step engineering tasks like root-causing and patching subtle bugs across large codebases and low-level systems.
Building on user feedback, we focused on improving model performance across a variety of domains, including coding, agentic, and scientific tasks, as well as full-stack web development and multimodal understanding. With improved quality of output and artifacts in web development, Carbon jumps +89 elo points to land at #4 (1769) on
WebDev Arena
.
State-of-the-art cybersecurity performance to help build secure systems
Gemini 4 Carbon delivers a significant leap in cybersecurity capabilities. It achieves state-of-the-art performance across the cybersecurity defense lifecycle — vulnerability detection, validation, and remediation.
Our teams are already seeing strong gains in cyberdefense. On internal benchmarks, Carbon achieves more than 2x uplift in success rate for generating secure code over Argon. As another example, the Chrome team has reported that Carbon performed more than 10X better than another lab's large frontier model when generating high quality patches. Wiz, our leading Cloud security platform, also observes Carbon leading on benchmarks for web penetration testing, a core capability for
Wiz's Scan for Good
initiative.
Carbon excels across key external benchmarks (evaluated without guardrails):
Finding real vulnerabilities:
Core to cybersecurity defense is finding real vulnerabilities. Carbon achieves a state-of-the-art 88.2% on
SEC-bench Pro
, autonomously uncovering complex flaws buried in real-world software.
Validating risk through exploitation:
To prioritize which vulnerabilities to remediate first or remediate at all, cyber defenders increasingly rely on models to check which vulnerabilities are exploitable. Carbon sets a new state-of-the-art on the popular exploitation benchmark
ExploitGym
(54.8%).
Patching at the root cause:
Ultimately after identifying the vulnerabilities, fixing the root cause is a critical step in the cybersecurity defense lifecycle. Carbon reaches 71.0% on Collinear’s
CWE-bench
, turning validated findings directly into working code fixes.
Advancing frontier model safety & security
Gemini 4 Carbon builds on the same multi-layered safety and security stack of Argon — combining model training, real-time misuse defenses, prompt-injection resilience, and chain-of-thought monitoring. In particular, we made significant strides in model alignment with Argon, and reported its propensities to behave in an aligned way in our
Safety and Security report
. With Carbon, we challenged ourselves to go a step further on alignment, and trained the model to respond to complex or high-pressure tasks in the right way.
Reducing shortcuts and loophole exploitation:
With Carbon, we further mitigated shortcut attempts in training while ensuring high-quality coding performance. Carbon reduced successful cheating on Terminal-Bench 4.0 to 0.0%, with attempts to cheat dropping to 0.4% — all while improving overall accuracy. In live coding environments with our internal teams, we observed that high-severity misalignment alerts dropped by almost 80%.
Greater transparency and honesty:
In our internal testing, Carbon cuts unsupported claims by approximately 2x over Argon. It puts methodological caveats directly into the deliverable or withholds blocked actions with a clear list of what remains required, rather than fabricating or hedging around missing evidence.
Improved collaboration with the user in the face of ambiguity:
Rather than guessing or forcing a path forward, Carbon retrieves the relevant sources and surfaces discrepancies to the user before acting — as a result, users should observe a much better collaborative experience with Carbon.
Following through without overstepping:
Carbon simultaneously reduced overreach by 26% and under-service by 29% resulting in much more reliable execution of multi-step plans end-to-end while respecting project constraints and staying strictly within scope.
Resisting prompt injection:
While Argon previously led the Gray Swan’s Indirect Prompt Injection (IPI) Benchmark in prompt injection resistance with a very low 0.7% attack success rate, Carbon achieves 0.0% — resisting every evaluated attack attempt.
Coming soon to developers, businesses, and consumers
Pushing the frontier forward requires moving fast while remaining deliberate about deployment. With Gemini 4 Carbon, our goal is to deliver meaningful leaps in software engineering and cybersecurity defense without compromising on safety or reliability. We’re eager to see how the initial cohort of cyber defenders use this model and we look forward to bringing Carbon to developers, businesses, and consumers soon.

We are excited to announce the release of
Hoot
0.10.0! Hoot
is a Scheme to WebAssembly compiler backend for
Guile
, as well as a general purpose
WebAssembly toolchain. In other words,
Scheme in the browser!
This release contains new features and bug fixes and since the
0.9.0
release
back in May.
Use Hoot in the upcoming Lisp Game Jam!
On Friday (October 30th 2026), the
autumn edition of the Lisp Game
Jam
will begin! It's
a 10-day long game jam where participants make games using their
favorite flavor of Lisp.
Does making a small web game in Scheme using Hoot sound appealing to
you? Well, then we have just the thing to get you started: the
Hoot
game jam
template!
This
template project has everything you need to start making an HTML5 game
with Hoot quickly.
The template repository includes:
Bindings to the necessary web APIs to make an interactive game with
HTML5 canvas
A Makefile for compiling, running a development web server, and
generating a .zip bundle for uploading to itch.io
A very simple Breakout-like example game that demonstrates how to
put all the pieces together
For more inspiration, here are some games made with Hoot for past
jams:
Added module name to contextualize duplicate import errors.
Added support for library versioning for R6RS compatibility.
Fixed default version for
define-module
libraries.
Fixed
locate-library
not respecting configured load extensions.
Previously, we were using Guile's load extension parameter instead
of Hoot's own.
Runtime changes
Added
%struct-ref
and
%struct-set!
primitives for accessing
record types defined using the interpreter.
Stopped raising errors when importing an undefined symbol in the
runtime module system. Guile is lax about this so Hoot being strict
caused compatibility issues.
Fixed optional argument parsing in
primitive-eval
.
Fixed keyword argument parsing for procedures with both optional and
keyword arguments in
primitive-eval
.
Fixed error messages regarding runtime module registry to include
the correct CLI flag:
-fruntime-modules
.
Scheme changes
Added partial implementation of
SRFI-13
: String
Libraries. It's just a set of re-exports, very similar to Guile,
but Guile's SRFI-13 module is not declarative and is thus rejected
by Hoot's compiler.
Added partial implementation of
SRFI-60
: Integers
as Bits.
Added
define-macro
,
defmacro
,
delete
,
list->symbol
, and
symbol
to
(guile)
.
Exported
define-syntax-parameter
and
syntax-parameterize
,
symbol-append
,
integer-length
, and
gensym
from
(guile)
.
Added
list->bitvector
and
bitvector
to
(hoot bitvectors)
and
re-exported them in
(guile)
.
Implemented
get-bytevector-all
in
(rnrs io ports)
.
Made
bytevector=?
a publicly exported procedure from
(hoot bytevectors)
and
(rnrs bytevectors)
.
Added
define-syntax-parameter
and
syntax-parameterize
primitives.
Improved
(ice-9 exceptions)
exports to more closely match Guile.
Added
(rnrs)
module.
Added
(rnrs base)
module.
Added
(rnrs syntax-case)
module.
Added
(rnrs r5rs)
module.
Added
(rnrs hashtables)
module.
Added
(rnrs files)
module.
Added
(rnrs enums)
module.
Added
(rnrs exceptions)
module.
Added
(rnrs arithmetic fixnums)
module.
Added
(rnrs records inspection)
module.
Added
(rnrs records procedural)
module.
Added
(rnrs records syntactic)
module.
Added
(rnrs io simple)
module.
Added
(rnrs io ports)
module.
Added
port-has-position?
to
(hoot ports)
for R6RS compatibility.
Added stubs for centered division to
(hoot numbers)
and a stub for
integer-length
to
(hoot bitwise)
for R6RS compatibility
(eventually).
Rewrote
(rnrs bytevectors)
as an R6RS module with version
(6)
.
Fixed
number->string
to round floating point decimal part to an
even digit.
Fixed
number->string
for floating point numbers ±2^N, where 52 <=
N <= 1023.
Fixed incorrect bytevector copy in
number->string
floating point
conversion algorithm.
Fixed
min
/
max
macros not working when given zero arguments.
Fixed the parameters to the
log
procedure in
(guile)
.
Fixed the implementation of
negate
in
guile
. It was doing
entirely the wrong thing.
CLI changes
Port numbers are now validated to be exact integers in the range [1,
65535].
Actually complain about invalid option or unknown subcommand.
Previously, the code that was supposed to do this was unreachable.
Add
--experimental-wasm-exnref
feature flag when running
hoot compile --run=node
for continued compatibility with supported
NodeJS versions that don't have the new Wasm exnref feature enabled
by default.
Fixed build-time disabling of
hoot server
. In past releases, the
hoot
CLI script would still attempt to load should-be-optional
libraries that
./configure
had already determined to be missing.
Thanks to mcc for discovering this blunder.
Documentation changes
Improved instructions in "Building from source" section of the
manual.
Dependencies are now mentioned in the "Advanced path" section of the
README
.
Updated project template
README
to say Guix is
not
required
(though it's still the easiest option).
Browser compatibility
Compatible with Safari 26 or later.
Compatible with Firefox 121 or later.
Compatible with Chrome 119 or later.
Get Hoot
Hoot is available in GNU Guix:
$ guix pull
$ guix install guile guile-hoot
Also, Hoot is now available in
Debian
, though it will
take awhile for this release to make it there.
Otherwise, Hoot can be built from source via our release tarball. See
the
Hoot homepage
for a download link and GPG signature.
Documentation for Hoot 0.10.0, including build instructions, can be
found
here

Sony Network Communications has confirmed a data breach that compromised approximately 2.5 million records containing current and former customers’ personal information.
A Sony Group Corporation subsidiary, the company provides telecommunications and technology services, acting as an internet service provider (ISP) in Japan.
The breach occurred on October 19 and was detected four days later, when the company shut down the compromised servers and blocked external communication.
In an
announcement yesterday
, the company said that its So-net member database, supporting its internet access service, was accessed by an unauthorized party.
The investigation confirmed that a total of 2,585,481 customer records had been exposed, including the following types of information:
Full names
Phone numbers
Email addresses
User IDs
Dates of birth
Gender
Internet Connection IDs
No banking, payment card, or other account details were exposed.
An additional 54,401 email addresses from several email services were also exposed along with account passwords. The company advises users to change their passwords.
In the breakdown of exposed records, Sony Network Communications says there are 2,141,986 So-net entries and 443,495 plala (S Course) records. The latter impacts another internet service provider, NTT Docomo, which contracts Sony Network Communications to provide its Docomo Hikari services.
NTT Docomo also
notified customers
about the breach and
warned of phishing emails
and fake websites impersonating its d POINT Club and a Universal Studios Japan (USJ) campaign, falsely claiming that recipients had won and prompting them to enter personal information to claim tickets.
Docomo says the incident affects all current Hikari service clients and those who canceled within the preceding six months.
Sony reported the incident to Japan’s Personal Information Protection Commission and is investigating its cause and scope.
As of October 27, neither company had confirmed misuse of the exposed data in the wild.
Since the start of the year, multiple cyberattacks have targeted high-value companies and providers in Japan.

GitHub Octoverse 2026
. I'm at GitHub Universe today (GitHub gave me a free ticket through their "GitHub Stars" program). EVP Jay Parikh just announced this year's Octoverse report, and highlighted these numbers in particular:
This is a pretty stark representation of the impact of agentic engineering on GitHub. In 2026, merged pull requests tripled in less than a year to 220 million per month. Commits more than tripled to 7.38 billion per month, with most of that increase in the second half of this year. New repository rate doubled this year, to 30.3 million per month.
The report includes new numbers by industry, and breaks out numbers for repositories that involve "interoperability or reverse engineering". The
methodology section
includes notes about how they did this:
Top countries by pushes to public repositories, adjusted by profile location
. Pushes from each country were summed across the Octoverse year. To adjust for biases caused by VPN usage, LLM classification was used to extract the ISO 3166-1 alpha-2 code from the profiles of GitHub users who contributed pushes during this period [...]
Industry
. Public repositories created 2022 to 2026 were sorted into NAICS sectors by a fine-tuned multilingual embedding model using name, description, topics, and README, from random samples per year. [...]
Interoperability
. Counts public repositories created each year whose name, description, topics, or README mention interoperability or reverse engineering, or related terms, such as clean room implementation, drop-in replacement, or protocol re-implementation.
GOTO Considered Totally Sick (for error handling in C)
I recently started writing C again for the first time since 2018, and handling errors has been an especially difficult adjustment coming from languages like Go and Zig that coddle me with their wonderful
defer
and
errdefer
. Then I read some
emails from John Carmack on inlined code
that gave me an epiphany on writing cleaner error handling code, and now I want to share it with the world.
But First Let’s Defer
I write Go all day at my dayjob, and error handling is pretty trivial. When there’s an error we wrap it and bubble it up, and let some top dog up the call stack figure out what they want to do with it. If there is resource cleanup involved, it’s made easy with
defer
:
typeDoerinterface {
MightError(int) errorLock()
Unlock()
}
funcSomeFunc(dDoer) error {
d.Lock()
deferd.Unlock()
iferr:=d.MightError(3); err!=nil {
returnerrors.Wrap(err, "Doer.MightError()")
}
// the rest of this very important function has been hidden from you for esoteric reasons
}
Sometimes there’s more complicated handling, but in 99% of scenarios it’s that simple because Go doesn’t have manual memory allocation and you don’t need to worry about cleaning it up when there’s an error.
Zig on the other hand does require you to manually manage memory, which I find a little more difficult because I’m not experienced enough for it to be second nature like it is when I write Go. Here’s a snippet from my toy multiplexer that uses
errdefer
:
fninit(allocator:std.mem.Allocator,env_map:*std.process.Environ.Map,cfg:Config)!Model{constsh=env_map.get("SHELL")orelse"/bin/sh";constshell_z=trystd.fmt.allocPrintSentinel(allocator,"{s}",.{sh},0);errdeferallocator.free(shell_z);constposix_block=tryenv_map.createPosixBlock(allocator,.{});errdeferposix_block.deinit(allocator);consttabs:[]Tab=tryallocator.alloc(Tab,cfg.commands.len);errdeferallocator.free(tabs);constpipes:[]Pipe=tryallocator.alloc(Pipe,cfg.commands.len);errdeferallocator.free(pipes);// all done with allocations (and errors)errdefercomptimeunreachable;// the rest of this function has been stolen by bilgerats}
I’m allocating memory for several types, and because any one of the allocations can fail I need to handle freeing up each succesful memory allocation that preceded the failure. Zig’s
errdefer
makes this easy, there’s no manual tracking of what needs to be freed at any point, because the deferred statements will execute in reverse order if the function returns an error. Also I’m following the
Reserve First
pattern, which is where I learned
errdefer comptime unreachable
from.
This is the C Part
Now, enter C. There’s no
defer
or
errdefer
. I’ve painted myself into a corner with some ugly code a few times because I’m so used to those tools that I don’t regularly plan ahead for what my error handling control flow will look like. Until recently I’ve been writing code that looks like this:
Do you see how resource cleanup is slightly different across each error handling if-block? Yuck! Yeah yeah yeah, I know it’s a terrible, contrived example, and nobody would ever write C like this. Except me like 3 weeks ago. I knew something was wrong when I wrote code like this, but I was hopelessly
defer
-brained in a world where
defer
hadn’t been born yet. Some classmates had mentioned using
goto
but I couldn’t really wrap my head around it. (We can’t share code with eachother otherwise the university would have us killed).
Then when I read those
John Carmack emails
something clicked. Carmack doesn’t mention
goto
explicitly, but these two thoughts in particular were the special sauce I needed to help me understand (emphasis mine):
A quote from Henry Spencer describing control flow in some flight software:
It disallowed both subroutine calls and backward branches, except for the one at the bottom of the main loop.
Control flow went forward only
. Sometimes one piece of code had to leave a note for a later piece telling it what to do, but this worked out well for testing: all data was allocated statically, and monitoring those variables gave a clear picture of most everything the software was doing.
And Carmack on moving code out of large conditional blocks (emphasis mine):
Enclosing pages of code inside a conditional or loop statement does have readability and awareness drawbacks, so leaving that code in a separate function may still be justified, but in some cases it is still possible to
move the code to another place where its execution wouldn’t be conditional
, or just
execute it at all times
and inhibit the results in some way with a very small conditional block.
Ohmygodigetitnow. Instead of having multiple exit points scattered throughout my function, each performing their own resource cleanup, I can put all resource cleanup behind a single exit point at the very end of the function. Guarding cleanup behind the default return, only reachable using a
goto
, is kinda like a psuedo-
errdefer
. Hooray! Hooray for John Carmack and Henry Spencer!! Now let’s rewrite the function above using this brand new discovery:
I’d say that’s much simpler to read! And it should be less prone to bugs from expanded responsibilities over time, because there’s only one spot where resource cleanup needs to be modified. You could also use multiple labels to split cleanup into sections, if you only wanted to cleanup a subset of resources. I’m sure this is an obvious concept to most seasoned C programmers, but I’m real happy I learned something new that’ll help me write better code.
Update
: after sharing this post on IRC, I got some helpful feedback about using
calloc
instead of
malloc
when doing allocations that might overflow (i.e.
n * sizeof(T)
), and some restructuring of the for loop in the second C example that makes the code even simpler.
Chi Ian Chan spent his first 30 years in O'ahu, Hawaii, growing up in Honolulu's Chinatown. And he's quick to tell you that he never surfed a day in his life (he prefers skateboarding). Four years ago, he left his native island for Manhattan—specifically, Hell's Kitchen—to be with his now-wife and business partner Lizzy Han.
Chan loves his new home, but he told Hell Gate that the thing he missed the most about life in the South Pacific was musubi, the classic Hawaiian rice-and-Spam snack that's ubiquitous in Honolulu, but shockingly difficult to find here.
(Scott Lynch / Hell Gate)
"There was no musubi in New York that satisfied my cravings," he said, "so I made my own." Chan started selling it over a Facebook neighborhood group. That led to a series of Sunday musubi pop-ups at an Upper West Side sushi restaurant, and then, upping his commitment in May of 2025, to signing a lease for a slender space on prime West 72nd Street. After sixteen months of waiting on permits and for construction to be completed, the neighborhood now boasts the city's only musubi shop,

On 17 October, Meta
suspended the official Instagram account
of the No Kings Coalition during a nationwide campaign that was aimed at encouraging Americans to vote early in the 3 November midterm elections. Almost
3,000 events
were taking place across the United States. Organisers lost access to their account at approximately 1:30pm Eastern Time, when they needed it to communicate with participants.
Meta initially blamed excessive posting, sharing, and commenting. The following day, its Vice President of Communications,
Andy Stone
, changed the explanation. Meta now claims that software using Claude AI was reading Instagram profiles, posts and hashtags at 4 times the normal rate.
The account became publicly visible again after approximately 90 minutes, but organisers couldn’t publish anything until
Meta restored access
hours later at 5:33pm.
Meta censored a political organisation during a national voting campaign, blamed its own automation, then claimed its automated systems had detected another automated tool. Meta admitted the suspension was wrong, but none of its explanations account for what happened from a technical standpoint.
Meta’s response is exactly what independent technical experts like me have warned about. I point this out because we can’t allow tech companies to avoid responsibility and accountability for their actions by blaming AI.
Tech companies are blaming everything but themselves. Meta is a company whose technology can infer what flavour of ice cream a 7-year-old likes from something her uncle’s dog posted on Instagram in 2020, yet apparently can’t explain why its own systems censored a political organisation at one of the most critical moments in its history.
This is my independent technical analysis of Meta’s actions, not an endorsement of the No Kings Coalition or its politics. It doesn’t matter if you support or oppose this organisation, you should be deeply concerned that Zuckerberg can censor anyone, including people or organisations you support, without providing evidence or accountability. The same filters can be used against anyone whose views conflict with Meta’s commercial or Zuckerberg’s political interests, now or in the future.
Stone blamed unusually frequent activity by the account itself, but the organisers disputed this, saying they’d published only a handful of posts and were livestreaming the events. Given how easily Meta’s own records could prove or disprove that claim, I suspect the company needed a more convincing explanation.
A day later, Stone provided a different explanation, saying the activity was primarily the account’s “reading” behaviour.
Posting and reading are completely different activities, something a competent developer or data scientist could identify within minutes by examining the activity logs.
Publishing posts, sharing content and commenting involve sending information to Instagram. Reading profiles, posts and hashtags involves requesting information from Instagram.
Meta initially blamed the organisation’s publishing activity. Its engineers then identified reading activity instead.
Stone should explain what evidence supported his first and second statement.
In his revised statement, Stone said Meta’s security systems had detected “the use of a Claude tool reading profiles, posts, and hashtags”.
Meta explicitly named Anthropic’s AI software but didn’t identify the tool, who operated it or whether the No Kings organisers had authorised it.
Is Meta suggesting that using Claude to access Instagram is prohibited?
If so, which policy was violated? If not, why did Meta suspend the organisation’s account instead of restricting the automated requests?
Stone said the rate of requests “sharply increased (~4x volume) in intense bursts”.
Four times what?
If an account normally receives 100 requests during a particular period, four times that means 400. If it normally receives 100,000, the increase means 400,000.
My LinkedIn posts typically reach between 2,000 and 250,000 readers, while my posts on X range from 1,500 to 1.2 million. Sudden increases in activity are normal on social media.
Stone’s reference to “intense bursts” sounds alarming but provides no meaningful technical information without the actual request counts, timeframe and frequency.
Even a small number of automated requests can arrive in intense bursts. What Meta hasn’t established is why those requests justified suspending the organisation’s account.
Reader counts and automated requests are different measurements, so the size of an audience alone cannot establish whether Meta’s security threshold was reasonable.
Without the actual numbers, the measurement period and Meta’s security thresholds, the figure doesn’t tell us anything.
The No Kings Coalition was coordinating almost 3,000 events. Increased activity involving its Instagram account was entirely predictable.
Meta is using a percentage without providing the numbers needed to determine if the activity justified suspending a political organisation.
Stone said the requests “resembled automated bot traffic rather than an ordinary human browsing our systems”.
I founded a venture-backed cybersecurity company in Silicon Valley in 2010 and built the first security chatbots in the world - they automated actions on platforms like Slack, HipChat, Messenger, and Telegram between 2015 and 2019. I can say with confidence that automated activity isn’t inherently a security violation. No competent cybersecurity professional or chatbot developer would automatically classify automation as malicious. That makes no technical sense. Search engines, monitoring tools, research applications and AI assistants make billions of automated requests every hour of every day. Platforms have systems that are designed to identify excessive traffic, restrict access credentials and block requests that violate their policies.
Does Meta apply the same restrictions to people using its own AI assistant, Muse, to automate interactions with Facebook and Instagram? If not, why?
Stone claimed an automated review recognised the suspension was wrong and restored the account approximately an hour later. This is disingenuous. Meta restored public visibility, but the organisers remained locked out for hours. By saying the account had been restored, Stone concealed the fact that Meta was still preventing the organisation from publishing. Even when explaining a mistake of this magnitude, Meta chose language that obscured what actually happened.
The No Kings organisers reported that their Instagram page became publicly visible again after approximately 90 minutes, but they still couldn’t use it. People managing the account remained locked out until 5:33pm Eastern Time.
Meta’s own automated review had already decided that the suspension was wrong, yet the organisers remained unable to publish posts or communicate with supporters during their nationwide campaign.
Stone later said that restoring administrative access took additional time. Why? The only credible explanation in my view, is that restoring meaningful access required a Meta employee with the necessary authority. That suggests someone had to approve the reversal of a suspension Meta had already admitted was wrong. Meta should identify who controlled that decision, who authorised the restoration and why the organisers were kept locked out.
Restoring an Instagram page that its organisers still can’t use doesn’t restore their ability to communicate. Meta’s decision to censor them continued affecting the organisation after its own systems had recognised the suspension was wrong.
Stone described the original enforcement action as “clearly taken in error”. There’s nothing clear about it. It’s clear to me that the opposite to what he says is more likely to be true.
An automated system doesn’t independently decide which behaviour violates Instagram’s policies, especially when it comes to such prominent accounts.
The No Kings Coalition is one of America’s most prominent anti-Trump movements, organising nationwide demonstrations that involve millions of people across thousands of locations. Suspending its Instagram account during a major mobilisation campaign was a politically significant decision with predictable consequences.
Given the organisation’s prominence, the timing and the public backlash, multiple Meta teams and senior managers had to be involved in decisions about the suspension and restoration. Zuckerberg himself would have been involved, given his hands-on approach to major content moderation decisions.
This wasn’t simply a software error. People made the decisions, and Meta’s automated systems executed them.
Restoring public visibility while keeping organisers locked out required separate enforcement decisions that Meta has yet to explain.
Meta’s records can identify which individuals reviewed the incident, who authorised changes, whether senior executives were briefed and why restoring full access took hours.
I wrote
article
18 hours ago to explain how in Brazil, Meta
blocked the sitting president
(Luiz Inácio Lula da Silva) from running normal paid Instagram promotions while its algorithms and WhatsApp recommended his opponent Flávio Bolsonaro.
Its AI refused
basic Lula campaign material but produced the equivalent for Bolsonaro. Some of Meta’s staff flagged the unequal treatment in real time and escalated it; the company later offered
shifting technical excuses
that don’t match the dates or the fact that Bolsonaro’s campaign kept using the same tools Lula couldn’t access.
During the election, Meta ran over
1,600 political ads
that researchers found were illegal, almost all paid for in US dollars, and only reclassified or removed them after they’d already been shown up to 171.1 million times. Complaints about account suspensions
increased 585%
during the election year.The Brazil case doesn’t establish that the No Kings suspension was coordinated or deliberate. It establishes another example of politically consequential account restrictions that Meta attributed to technical failures.
Meta controls when political organisations and parties can publish, advertise, appear in recommendations and communicate with their audiences. For high-profile accounts, Meta’s executives are responsible for making those decisions, not automated systems.
Meta has logs that record absolutely everything. They know precisely what triggered the suspension, who or what caused it, which restrictions were imposed and which employees were responsible for each and every action. It also knows why organisers remained locked out after the suspension was reversed.
Meta might not document every decision made by its employees, but its system logs contain the technical evidence needed to explain what happened, unless those records have been deleted.
The public deserves to know why Mark Zuckerberg’s company is censoring political organisations and individuals in ways that just happen to favour the White House’s political agenda, cutting them off from their audiences precisely when they need to communicate most.
Congress should summon the engineers and data scientists responsible for these systems, put them under oath and demand specific technical answers backed by system logs. They shouldn’t be allowed to hide behind corporate statements or blame automation for decisions made by people.
Meta’s engineers and data scientists should answer these questions and provide the technical records, internal communications, and enforcement logs to support their answers. Calling policy staff is pointless. They’ll either deflect or lack the technical knowledge to explain what actually happened.
Why did Andy Stone initially blame excessive posting, sharing and commenting when Meta later blamed reading activity?
What evidence supported his first statement, who approved it and when did Meta establish that the explanation was incorrect?
What constitutes fair and acceptable use of Instagram by automated tools?
Which activities are permitted, what limits apply, and what specific policy did the alleged Claude tool violate?
Do the same restrictions apply to Meta’s own AI assistant, Muse?
Can people use Muse to automate reading, posting and interacting with Instagram and Facebook? If so, why was No Kings suspended for alleged automation, and does Meta apply the same enforcement thresholds to its own AI tools and competing services?
What information was the tool accessing?
Was it reading publicly available content, using an authenticated account or attempting to access private information?
What does the fourfold increase actually represent?
How many requests occurred, over what period, and what was the normal level of activity? Is a fourfold increase an established threshold for suspending all Instagram accounts, or was a different threshold applied to No Kings? Provide the exact measurements, enforcement thresholds and comparable records showing how Meta treats other accounts experiencing the same increase.
Which security restriction triggered the suspension?
Was the decision based on request frequency, suspicious authentication, account behaviour or another classification? Identify the exact policy and technical conditions that triggered enforcement.
Why did Meta suspend No Kings instead of restricting the software making the requests?
What evidence established that the organisation was responsible? Why weren’t regular security controls, including IP blocking, rate limiting or access-token restrictions, sufficient?
Did Meta classify No Kings as a politically sensitive account?
Were its security thresholds, monitoring arrangements or enforcement procedures different from those applied to other big or contraversial accounts? Provide its account classifications and any associated enforcement policies.
Did any Meta employee manually review, classify, restrict or change settings associated with No Kings before or during the suspension?
Identify every action, its timestamp, the employee or team responsible and the reason recorded.
What happened during the automated review that reversed the suspension?
Which original finding was overturned, what evidence caused the reversal and which restrictions did the review actually remove?
Why were organisers still locked out after Meta recognised that the suspension was wrong?
Which separate restriction remained active, why wasn’t it automatically removed and who or what eventually removed it?
Did any Meta employee manually restore administrative access?
Provide the audit records showing when access was restored, which systems were involved and whether an employee intervened.
What happened to scheduled posts, livestreams, notifications and other communications during the suspension?
How many people would otherwise have received those communications, and did Meta measure the disruption?
How many political organisations have experienced comparable suspensions?
How often has Meta blamed automated activity for restrictions that subsequent reviews found were incorrect? Provide figures for suspensions during elections, protests and other major political events.
Did Meta communicate with any US government official, political campaign, intelligence agency or external organisation about No Kings before or during the suspension?
Identify the participants, dates, subjects discussed and whether any communication concerned account restrictions or content distribution.
Will Meta permit independent investigators to examine the account classifications, security logs, enforcement records and restoration history?
If not, why?
Were any manual configuration changes, overrides, blocklists or changes to enforcement thresholds applied to No Kings or associated hashtags within 72 hours of the suspension?
Identify every change, who authorised it, when it took effect and if it was reversed later on.
Did Meta open an internal security or engineering incident involving No Kings before, during or after the suspension?
Provide the incident severity, timestamps, assigned teams, tickets and relevant internal communications between security, engineering, public policy and trust and safety employees.
Does Meta use automated account restrictions or reduced content distribution for accounts involved in political mobilisation?
Identify the policies, account classifications, automated enforcement conditions and any testing programmes that can restrict political accounts during periods of unusually high engagement.
Can Meta establish that No Kings would have been suspended under exactly the same conditions if it had been a commercial brand, celebrity or non-political organisation?
Provide comparable enforcement records and explain if the coalition’s political classification influenced the decision.
Did Meta’s systems suspend No Kings because of a standard security policy, a special account-level configuration or a manual decision implemented through automation?
Provide the configuration history, original enforcement trigger, account-specific settings and audit records needed to establish which explanation is correct.
Meta should not be allowed to answer these questions with another statement about automated systems. Its executives should provide the records that establish what those systems were instructed to do, who authorised those instructions and why the No Kings account was suspended.
If Zuckerberg wants people to believe this was an innocent automated mistake, Meta should release the records that establish it. An apology isn’t evidence.
I used three AI models to help edit and refine this article. All the research, analysis, connections I’ve made between people, companies and events, and the opinions and conclusions are mine. I’m dyslexic, like 35% of entrepreneurs, so I used AI to improve my writing, not to do my thinking.
Never miss an investigation. Get every post as it’s published, plus 1 weekly briefing linking to everything I wrote that week across technology, governments, intelligence, legislation and corporate power.
Always free.
Every investigation begins with the core insight, then explains the technical capability, incentives, relationships and evidence behind it.
I examine technology, AI, surveillance, cybercrime, digital identity, privacy, online safety, intelligence, legislation and the companies, governments and investors shaping them.
Most posts take only a few minutes to read. Around once a month I’ll publish a longer investigation when a subject deserves deeper analysis.
You can now see what investigations I’m working on before I publish them. I’ve created a
drafts page
so you can see what I’m likely to write about next.
Too much reporting separates events that belong together.
A government announcement becomes one story. An acquisition becomes another. An investment, a technical capability, a policy change or an executive statement becomes something else entirely.
I investigate how those pieces connect. I don’t begin with conclusions. I begin with technical capability, evidence and incentives. Intent is the last thing I consider, not the first.

Volt Typhoon hides zero-day attacks using 'Silent Train' framework

Chinese state-sponsored hacking group Volt Typhoon has been using a framework that relies on rotating chains of connected devices compromised on demand, including for zero-day attacks targeting high-value systems.
The framework has been dubbed Silent Train because the threat actor uses it against select targets, cleans it up after each operation, and refreshes it continuously.
Researchers at Black Lotus Labs, the threat research division of communications company Lumen, have been tracking Silent Train for three years and confirmed that Volt Typhoon exploited at least four zero-day vulnerabilities in attacks targeting edge and management infrastructure.
Targets include telecommunication firms, government agencies, defense contractors, educational institutes, utilities/critical infrastructure, satellite service providers, IT firms, MSPs, transportation, aviation, and emergency services.
Black Lotus Labs’ observations indicate the most targeted regions are California, Texas, and Hawaii, suggesting a focus on Indo-Pacific matters.
Victims map

Volt Typhoon previously targeted U.S. critical infrastructure, including communications, energy, transportation, and water systems, with
CISA warning
that it seeks to establish access for potential disruption during a future crisis or conflict.
According to the researchers, Silent Train's deployment was partly fueled by the
FBI's disruption of KV-Botnet
, a botnet that Volt Typhoon used to evade detection when attacking critical infrastructure in the US.
Activity comparison over time
Source: Black Lotus Labs
Silent Train relay network
Silent Train is practically a relay infrastructure formed of compromised devices that Volt Typhoon uses to hide the origin of its attacks.
The operators route their activity through VPS infrastructure outside the United States, then pass it through hacked devices such as routers that act as intermediate relays before launching attacks.
Black Lotus Labs says Intelbras modems served as overseas relays, while Netgear Orbi devices acted as hops in the U.S.
Silent Train attack overview
Source: Black Lotus Labs
The threat actor's use of Silent Train involves exploiting vulnerabilities, stealing credentials, exfiltrating data, and maintaining persistent remote access to compromised systems.
By monitoring Silent Train activity, the researchers were able to observe zero-day exploits for the following products:
Compromising these platforms gives threat actors broad administrative control, enabling credential theft, remote access, and reach into downstream customers without the “noisy” lateral movement that might trigger detection.
Exploitation timeline
Source: Black Lotus Labs
“To construct these sessions, its operators exploit exposed web interfaces on SOHO, IoT, and other relay devices, then deploy only the tooling needed to enable chained SSH access through the compromised node,” Black Lotus Labs explains in a report today.
“This included temporary SSH services, keys, configuration files, and “live off the land” utilities.”
After the session ends, typically in under 8 hours, the threat actors remove all their tooling, keys, and configuration files from the disposable relays.
By early 2025, researchers noticed that the framework become hybrid, using disposable relays alongside compromised enterprise systems thaat were retained between one and three months.
Black Lotus Labs believes Silent Train was reserved for high-value targets and careful, hands-on operations conducted on China Standard Time (CST) timezone. The use of zero-days against those targets further strengthens the assumption.
The researchers recommend strengthening security around centralized management systems, restricting internet access to administrative interfaces, rapidly patching vulnerabilities, and centralizing logs with longer retention.
They also advise monitoring for unusual administrative activity, reviewing trusted connections that could expose customer or partner networks, and following CISA and NCSC guidance on Volt Typhoon.

Anna was planning to sell her condo. She had moved out in August 2024 and wanted to know whether closing in October 2026 or January 2027 would be better for taxes.
An AI agent reviewed both options and correctly concluded that either date would satisfy the residence requirement for a tax break worth up to $250,000 in excluded gains.
But it left out an important deadline.
Under the usual rules, homeowners must have lived in a property for at least two of the five years before selling it to qualify for the exclusion. Because Anna moved out in August 2024, she would stop satisfying that requirement around the end of August 2027. If her sale was delayed beyond August 2027, she could lose eligibility.
Across five attempts, Astra never identified the deadline. Opus identified it in all five attempts.
The agent evaluated the proposed dates correctly, but its advice left Anna unaware of a deadline that could affect a major financial decision. A tax adviser should recognize consequential issues even when the client doesn't know to ask about them.
DAYJOB evaluates AI agents on professional tax assignments requiring specialized expertise, complex materials, and decisions that aren't fully specified in the initial instructions. Our earlier releases covered Healthcare and Finance. DAYJOB: Tax extends that work into tax preparation, compliance, and advisory services.
The benchmark contains 50 environments across eight areas of tax practice. Agents receive client requests and supporting records, then produce tax returns, workpapers, technical reviews, or client advice.
These assignments test professional judgment alongside tax knowledge, calculations, retrieval, and instruction following. Agents must decide what deserves investigation, resolve conflicting evidence, recognize when information is insufficient, and carry those decisions into their final work.
Results: Leaderboard and Pareto Frontiers
Claude Sonnet 5.5 leads with a 10.8% pass rate
on the
DAYJOB: Tax leaderboard
, followed by Claude Fable 5.1 at 9.6% and Claude Opus 5.5 at 9.2%.
We report pass@1 at a 95% rubric threshold. An attempt passes when it satisfies at least 95% of the task's criteria, which assess calculations, supporting evidence, consequential issues, and the completed deliverable.
Performance versus cost
We also compared model performance against average cost per trial.
Claude Sonnet 5.5 and Opus 5.5 occupy the high-performance end of the measured Pareto frontier.
The breadth of professional tax work
DAYJOB: Tax covers eight areas, each requiring different rules, records, and expertise:
Individual and family tax
Small-business tax
Partnerships
Property and investments
Estates, gifts, and trusts
International tax
Corporate transactions
Tax review and disputes
Some assignments require complete filing packages with supporting workpapers. Others ask agents to investigate transactions, review previous filings, or prepare advice about decisions clients haven't yet made.
What's inside the assignments?
The benchmark contains
1,789 workspace files
, with a median of 30 per assignment and as many as 123. These include 1,487 PDFs, 117 Excel workbooks, 38 Word documents, and additional emails, images, CSVs, JSON records, and text files.
The workspaces include filed and draft tax returns, K-1s, W-2s, IRS notices, general ledgers, payroll records, contracts, and correspondence. They also contain the less standardized evidence that tax professionals routinely work with.
One assignment includes a photograph of a
handwritten receipt for merchandise purchased for resale
. The agent must read the item descriptions and amounts, reconcile them with spending records, and determine how the purchases affect inventory and cost of goods sold.
Another assignment involves an industrial silo-services company whose client assumes it operates only in Alabama. But its
field dispatch log shows crews working across five states
. The job locations, crew sizes, and days on site provide evidence relevant to the company's multistate tax obligations.
Other environments are similarly varied. One involves a cross-border household whose Polish employment and property records must be reconciled with cryptocurrency exchange exports, wallet histories, and historical purchase lots.
Created and reviewed by tax experts
DAYJOB tasks begin with real-world professional workflows. Tax experts turn these situations into realistic assignments, developing the supporting records, expected outcomes, and grading criteria. Each task undergoes a three-layer expert review for correctness, completeness, and solvability.
Tax experts bring experience across corporate taxation, partnerships, individual returns, trusts, and multistate compliance. Their backgrounds include:
Corporate and private-equity taxation:
A tax attorney with over 10 years of experience at PwC, Deloitte, and Exxon, covering tax planning, compliance, audits, and controversy.
Partnership and corporate taxation:
A Baker Tilly Tax Director with experience at PwC, Moss Adams, and Windes, specializing in complex partnership allocations, consolidated corporate returns, REITs, and high-net-worth clients.
Real estate and individual taxation:
A tax professional with experience at Deloitte and EY, specializing in real-estate partnerships, individual taxation, and trusts.
A retirement plan built on an unverified assumption
A separating couple asked an AI agent how to divide their Roth IRA and 401(k). Opus 5.5 told them they weren't legally married and recommended keeping their accounts separate, with a cash payment to even out the balances.
It opened one response:
You aren't legally married, so neither account can be split without triggering taxes and penalties.
But the couple's own records raised doubts about that conclusion. Although they now lived in Florida, where new common-law marriages generally aren't recognized, they had previously lived together in Texas and held a ceremony in Colorado. Texas recognizes informal marriages under certain conditions, and a valid marriage established elsewhere may remain valid in Florida.
That distinction could change the tax consequences of dividing their retirement accounts.
Across all five attempts, Opus based its recommendations around the assumption that the couple was unmarried
, even when it acknowledged uncertainty. Astra recognized the need to verify their marital status in four of five attempts. One response advised:
We first need to confirm your legal marital status.
The client asked how to divide the accounts. The agent needed to establish whether they were married before recommending a course of action. The evidence that should have prompted that investigation was already in the files.
Where DAYJOB: Tax fits
Most existing tax benchmarks begin with a defined problem: a legal question to answer, a return to calculate, or missing taxpayer information to collect. These evaluations measure important capabilities, but much of a tax professional's work involves figuring out what the problem actually is. Clients provide incomplete instructions, records contain conflicting evidence, and consequential issues may never appear in the original request.
DAYJOB tests whether agents can handle that end-to-end responsibility
, including identifying issues the client overlooked, evaluating conflicting evidence, and deciding what needs to be done in the first place.
TaxBench
Can the model answer a difficult tax question?
TaxBench
evaluates 114 tax questions across multiple specialties, each with a defined problem and grading rubric.
DAYJOB also asks whether the client asked the right question.
Anna wants to compare two dates for selling her condo. Both satisfy the residence requirement for a tax exclusion, but does the agent warn her when that eligibility could expire?
TaxCalcBench
Can the model calculate an accurate return?
TaxCalcBench
evaluates tax-return accuracy against expected filing values, using realistic tax documents and taxpayer scenarios.
DAYJOB also asks whether the underlying records actually support the tax treatment.
A studio's ledger references an attached receipt, but the receipt is missing. Does the agent flag the missing evidence or incorrectly treat the reimbursement as verified?
TaxLab
Can the agent gather missing information and file correctly?
TaxLab
tests whether agents can question a simulated taxpayer, obtain missing information, and complete a federal individual tax return.
DAYJOB extends that responsibility across the wider tax profession.
The deliverable might be a partnership loss analysis, an estate return, a review of a disputed tax position, or a strategy letter.
The central distinction is how much responsibility remains with the agent.
DAYJOB evaluates whether agents can discover consequential issues, exercise professional judgment, and carry their findings through to a completed filing, review, or recommendation.
What DAYJOB: Tax measures
DAYJOB tests whether AI agents can take ownership of a professional assignment from start to finish. That means navigating messy records, identifying issues the client never raised, making sound judgments with incomplete information, and delivering work that meets professional standards.
The results show how difficult that remains for frontier models. Even when agents can perform the individual steps, exercising professional judgment and reliably carrying out real-world tax workflows remain out of reach.
This guest post by independent security researcher Ben Zimmermann was developed in collaboration with the Kingfisher team at MongoDB. Ben specializes in large-scale credential exposure research across public source-hosting platforms.
TL;DR:
I scanned
7,256,531 public repositories
on Gitee (China's largest indigenous Git hosting platform), using both TruffleHog and Kingfisher, and found
26,400 unique verified-live credentials
. Findings included an active organization-admin credential for a major enterprise AI platform and thousands of live cloud provider access keys.
What is Gitee?
Gitee, launched in 2013 by OSChina, was selected by China's Ministry of Industry and Information Technology as the country's national open-source code hosting platform. Its public API is severely constrained relative to GitHub and GitLab: no paginated projects endpoint, and the on-site code-search feature appears to have been retired years ago. A
2021 attempt
to study credential exposure on Gitee concluded that its APIs were too limited to scale the research.
Like any large Git platform, it's an attractive surface for credential exposure:
It is Git-based, so secrets buried deep in commit history persist.
It hosts millions of public repositories with active commit volume.
It has no public equivalent of the platform-vendor secret-scanning partnerships that have become standard on GitHub.
Enumerating millions of Gitee repositories
Gitee's public API is severely limited, so enumerating millions of repositories required combining many surfaces: the only official REST endpoint that returned useful data at scale, the platform's Explore feed, per-user repository and stargazer pages on the website itself, and Gitee's internal Elasticsearch widget that backs the on-site search UI.
Bootstrapping a username corpus
The single official REST endpoint that returned useful data at scale was
GET /api/v5/search/users?q=
. I hit it with three-character prefix queries (
aaa
,
aab
, ...,
zzz
) and combined the results with usernames extracted from the public Explore feed (
/explore/all?order=starred|popular|updated
). I then expanded that set via each user's following list and the stargazers of popular repositories. This produced a seed corpus of
1,704,759 usernames
.
Scraping per-user pages on the frontend
With the username corpus in hand, two per-user pages yielded repositories:
gitee.com/{user}/projects
(a user's own repos) and
gitee.com/{user}/stared_projects
(repos the user has starred). Page 1 of
/projects
returns full HTML; subsequent pages are AJAX-paginated (
X-Requested-With: XMLHttpRequest
). The stargazer-list pages used during username bootstrap paginate the same way, additionally requiring a CSRF token extracted from the page-1 HTML.
Querying the on-site search widget
A large fraction of the platform sits outside the social graph. To reach it, I used the same internal Elasticsearch endpoint that backs Gitee's on-site search UI:
so.gitee.com/v1/search/widget/wong1slagnlmzwvsu5ya
. It takes a
query
ID, a
q
parameter, and pagination via
from + size
:
Each query returned at most 20 results per page, with a hard cap of
200 results total
(
from + size <= MAX_RESULTS
) regardless of how many matches actually existed. For specific usernames, this was usually fine; for common usernames and trigram prefix queries against the widget, the cap silently truncated results.
Escaping the 200-result cap with bucket splitting
The widget's response includes Elasticsearch aggregations that bucket results by language (
编程语言
) and license (
许可证
). For the per-username scrape, when a query was capped, I split it by the language buckets the response already returned:
For trigram prefix queries against the widget (used to surface repos not associated with any user I'd discovered), I extended this into a BFS over a query tree: capped nodes split first by language, then by license, then by deeper prefix until each branch fit within 200 results.
After deduplicating repo IDs across all sources, this produced a working set of
7,256,531
unique public Gitee repositories.
Wiring up the scan pipeline
The next challenge was cloning and scanning the 7.25 million repositories. To do this in a single Python script, I used
Modal
, a serverless compute platform popular for AI workloads but well-suited to most parallel jobs. I ran TruffleHog and Kingfisher concurrently against every repository for increased coverage. Each surface verified credentials that the other missed, so running both caught more exposed credentials than either alone.
Figure 1.
Dual-scanner pipeline architecture.
The Docker image
The container image is a multi-stage build that pulls both scanner binaries from their upstream releases into a single Python base, plus git and OpenSSH for cloning:
The per-repo scan function
A single Modal function bare-clones each repo over SSH and runs both scanners concurrently as subprocesses against the same on-disk clone:
Dispatching 7.25M repos in batches
I split the corpus into 50 batches of ~150K repos and ran them sequentially at a steady 350 concurrent containers. Smaller batches were safer at this scale and easier to resume after interruptions; running larger batches was unstable and would hit clone-side blocks.
Cost and scale
Total wall time: roughly one month of continuous execution. Per-repo clone times were a major contributor: Gitee's servers sit in China, and cross-Pacific network distance plus SSH protocol overhead made each clone materially slower than an equivalent GitHub clone would be. The total cost was $3,097.64, fully absorbed by the $5,000 compute-credit sponsorship from Modal that supported this research. The same Modal + dual-scanner architecture works against most Git hosts with little more than a clone-URL substitution. I used a smaller-scale version of this approach in a
prior investigation of Algolia DocSearch admin keys
.
The results
Across the 7,256,531 public Gitee repositories scanned, the dual-scanner pipeline surfaced
26,400 unique, verified-live credentials
after deduplicating by token value.
Both scanners authenticate each candidate against its vendor's API at scan time (TruffleHog's
--only-verified
and Kingfisher's
--only-valid
modes), discarding anything that pattern-matches but fails to authenticate. The 26,400 figure is deduplicated by raw secret value, so duplicates across repositories or scanners count once.
Either scanner alone would have caught only about half of these credentials. The two tools' detector coverage was largely complementary: TruffleHog dominated Alibaba Cloud key detection (9,428 vs. 993), while Kingfisher dominated DeepSeek (2,940 vs. 230), OpenAI (1,198 vs. 150), HuggingFace (154 vs. 1), and Chinese-AI services like Zhipu (1,489 vs. 0) that TruffleHog has no detector for.
Secrets by type
The single most common leaked credential type was Alibaba Cloud AccessKey pairs: roughly
1 in every 766 Gitee repositories
contained a verified-live Alibaba Cloud credential.
Figure 2.
Credentials by vendor.
A long tail of additional vendors (LangSmith, OpenWeather, Algolia, PostHog, OpenRouter, MySQL, Stripe, Slack, Twitter, and others) accounts for the rest.
Secrets committed by date
The vast majority of verified-live credentials were committed in the last two years. 2025 alone accounts for 12,242 unique credentials, nearly half the entire dataset.
Figure 3.
Unique credentials committed by year.
Secrets by committer email domain
Most credentials were committed from personal mail services (qq.com, 163.com, gmail.com), making per-company attribution impossible at scale. The corporate-domain numbers below are a floor; even so, the names span major Chinese and Western tech companies alike.
Figure 5.
Unique credentials by committer email domain.
Smaller corporate footprints also appear from Oracle, Apple, Meta, Anthropic, and others, plus Chinese commercial and academic domains.
Gitee tops both Western platforms on raw count and per-repository density. One methodology note: the TruffleSecurity scans used TruffleHog alone, while this one used TruffleHog and Kingfisher together. TruffleHog's detector library skews toward Western vendors, and Gitee has heavy Chinese-vendor activity (Alibaba Cloud, DeepSeek, Zhipu, and others) that Kingfisher's coverage helps to surface; stripping our findings to TruffleHog-only puts Gitee at 1.76 per 1,000 repos.
Disclosure
I emailed the vendors with the highest exposure volume in this scan, providing each a coordinated report containing the full list of verified-live credentials associated with their service, along with source-repository metadata to help them attribute affected customers.
Per-developer notification (contacting the committer of each leaked credential individually) was not pursued at this scale. Vendor-side revocation is the more reliable path, since it doesn't require any action from the user who leaked the credential.
At the time of writing, revocation status for the disclosed credentials has not yet been confirmed.
Summary
Gitee is a meaningful credential-exposure surface.
26,400 verified-live credentials across 7.25M repositories. Per-repository density higher than comparable published scans of GitLab and Bitbucket.
Major tech companies appear in the committer metadata, Chinese and Western alike.
The breadth includes Huawei, ByteDance, Google, Microsoft, Oracle, and others, suggesting this is not a purely-Chinese-developer phenomenon.
Disclosure paths are asymmetric.
Western companies typically have bug bounty programs or accessible security channels. Most Chinese companies don't, leaving leaked credentials without a clear remediation path.
The architecture is portable.
The same Modal + dual-scanner pipeline works on most Git hosts with little more than a clone-URL substitution; the full scan cost roughly $3,000.

Amazon forest felled to build road for climate summit
Watch: Drone shots show scale of Amazon deforestation for COP30 road
A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit in the Brazilian city of Belém.
It aims to ease traffic to the city, which will host more than 50,000 people - including world leaders - at the conference in November.
The state government touts the highway's "sustainable" credentials, but some locals and conservationists are outraged at the environmental impact.
The Amazon plays a vital role in absorbing carbon for the world and providing biodiversity, and many say this deforestation contradicts the very purpose of a climate summit.
Along the partially built road, lush rainforest towers on either side - a reminder of what was once there. Logs are piled high in the cleared land which stretches more than 13km (8 miles) through the rainforest into Belém.
Diggers and machines carve through the forest floor, paving over wetland to surface the road which will cut through a protected area.

Claudio Verequete lives about 200m from where the road will be. He used to make an income from harvesting açaí berries from trees that once occupied the space.
"Everything was destroyed," he says, gesturing at the clearing.
"Our harvest has already been cut down. We no longer have that income to support our family."
He says he has received no compensation from the state government and is currently relying on savings.
He worries the construction of this road will lead to more deforestation in the future, now that the area is more accessible for businesses.
"Our fear is that one day someone will come here and say: 'Here's some money. We need this area to build a gas station, or to build a warehouse.' And then we'll have to leave.
"We were born and raised here in the community. Where are we going to go?"
BBC / Paulo Koba
Claudio Verequete says the trees he harvested açaí from have been cut down
His community won't be connected to the road, given its walls on either side.
"For us who live on the side of the highway, there will be no benefits. There will be benefits for the trucks that will pass through. If someone gets sick, and needs to go to the centre of Belém, we won't be able to use it."
The road leaves two disconnected areas of protected forest. Scientists are concerned it will fragment the ecosystem and disrupt the movement of wildlife.
Prof Silvia Sardinha is a wildlife vet and researcher at a university animal hospital that overlooks the site of the new highway.
She and her team rehabilitate wild animals with injuries, predominantly caused by humans or vehicles.
BBC / Paulo Koba
Sloths are among the animals frequently needing treatment after injuries caused by humans
Once healed, they release them back into the wild – something she says will be harder if there is a highway on their doorstep.
"From the moment of deforestation, there is a loss.
"We are going to lose an area to release these animals back into the wild, the natural environment of these species," she said.
"Land animals will no longer be able to cross to the other side too, reducing the areas where they can live and breed."
The Brazilian president and environment minister say this will be a historic summit because it is "a COP in the Amazon, not a COP about the Amazon".
The president says the meeting will provide an opportunity to focus on the needs of the Amazon, show the forest to the world, and present what the federal government has done to protect it.
But Prof Sardinha says that while these conversations will happen "at a very high level, among business people and government officials", those living in the Amazon are "not being heard".
The state government of Pará had touted the idea of this highway, known as Avenida Liberdade, as early as 2012, but it had repeatedly been shelved because of environmental concerns.
Now a host of infrastructure projects have been resurrected or approved to prepare the city for the COP summit.
Adler Silveira, the state government's infrastructure secretary, listed this highway as one of 30 projects happening in the city to "prepare" and "modernise" it, so "we can have a legacy for the population and, more importantly, serve people for COP30 in the best possible way".
Speaking to the BBC, he said it was a "sustainable highway" and an "important mobility intervention".
He added it would have wildlife crossings for animals to pass over, bike lanes and solar lighting. New hotels are also being built and the port is being redeveloped so cruise ships can dock there to accommodate excess visitors.
Brazil's federal government is investing more than $81m (£62m) to expand the airport capacity from "seven to 14 million passengers". A new 500,000 sq-m city park, Parque da Cidade, is under construction. It will include green spaces, restaurants, a sports complex and other facilities for the public to use afterwards.
BBC / Paulo Koba
João Alexandre Trindade da Silva hopes COP30 will leave a great legacy for the people of Pará state
Some business owners in the city's vast open-air Ver-o-peso market agree that this development will bring opportunities for the city.
"The city as a whole is being improved, it is being repaired and a lot of people are visiting from other places. It means I can sell more and earn more," says Dalci Cardoso da Silva, who runs a leather shoe stall.
He says this is necessary because when he was young, Belém was "beautiful, well-kept, well cared for", but it has since been "abandoned" and "neglected" with "little interest from the ruling class".
João Alexandre Trindade da Silva, who sells Amazonian herbal medicines in the market, acknowledges that all construction work can cause problems, but he felt the future impact would be worth it.
"We hope the discussions aren't just on paper and become real actions. And the measures, the decisions taken, really are put into practice so that the planet can breathe a little better, so that the population in the future will have a little cleaner air."
That will be the hope of world leaders too who choose to attend the COP30 summit.
Scrutiny is growing over whether flying thousands of them across the world, and the infrastructure required to host them, is undermining the cause.

Nvidia Nemotron 3.5 Transcribe: open ASR for 40 languages
One open model for multilingual transcription, speaker attribution, translation, and audio Q&A, with top leaderboard results, plus the open Granary v2 data pipeline and fine-tuning recipes to adapt it.
A transcript can capture every spoken word and still leave users or applications wondering who said what, how to translate it, or how to format domain-specific jargon. Multilingual calls, fast-paced meetings, and medical dictation each need different output: a translation, speaker labels, or correctly spelled medical terms.
NVIDIA Nemotron 3.5 Transcribe is an open-weight, promptable model that turns recorded speech into useful text, now available on
Hugging Face
and
ModelScope
. It brings transcription, speaker attribution (diarization), translation, and audio question answering into one checkpoint: it transcribes 40 languages, translates 31 of them to or from English, and attributes speakers in 13. It handles recordings up to an hour long and labels up to eight speakers. Developers can guide output with natural language, choose where their audio is processed, and adapt recognition to domain vocabulary and accents.
Granary v2’s multilingual data (available on
Hugging Face
and
ModelScope
) and reusable curation pipeline, together with
NeMo Speech fine-tuning tools
, extend prompt-level control to training: developers can define the written form they need and adapt the model to the speech their applications encounter. In a
medical case study
, fine-tuning cut word error rate (WER) on held-out speakers by 45.8% relative to the best prompt.
Guide transcription and analysis with natural language
The same checkpoint can turn one meeting recording into different outputs, depending on the instruction:
“Transcribe this recording and label each speaker.”
“Translate this audio into English.”
“What decisions were made in this meeting?”
Experience the model in action in the video below, where it tackles a classic scene from the 1940 screwball comedy His Girl Friday—a film famous for its rapid-fire, heavily overlapping dialogue.
Nemotron 3.5 Transcribe captions a scene from His Girl Friday (1940) and labels speakers, including overlapping dialogue.
For unfamiliar terms, try context before training. In a healthcare setting, for example:
Transcribe this medical discussion in the original language. Possible terms: HbA1c, metformin. Use these terms only when supported by the audio. Preserve standard medical spelling and write numbers in conventional written form.
The
model card
has recommended presets, including reasoning for audio questions, plus the full prompt guide and a task-by-language matrix: language support differs by task, and audio question answering is trained in English. Word-level timestamps are also supported. As with any speech model, spot-check names, speaker changes, and answers against the recording.
From live classes to lasting lessons.
Agora, whose real-time voice and video platform powers live conversations in apps, used word-level timestamps in a classroom demo: Nemotron 3.5 Transcribe turns a recorded class into a transcript shown alongside the replay, so students can see what was said and when.
Agora’s blog
walks through how they built it.
Leaderboard wins from transcription to speaker attribution
Among open-weight models, Transcribe leads on what was said; on who said it, it tops two speaker-attribution benchmarks outright.
Hugging Face Open ASR Leaderboard.
The leaderboard measures transcription accuracy as word error rate (WER) on public test sets, in three tracks:
English:
first among open-weight models at 5.33% average WER (Figure 1).
Multilingual:
4.62% mean WER across seven languages, the lowest among evaluated open-weight models in the model card’s Open ASR comparison.
Long-form:
10.98% mean WER, also the lowest in that comparison.
Figure 1. Nemotron 3.5 Transcribe ranks first among open-weight models on the
Hugging Face Open ASR Leaderboard
(English) at 5.33% average WER, with API models excluded. Lower WER means fewer transcription errors.
Artificial Analysis Speech-to-Text Leaderboard.
Artificial Analysis independently ranks speech-to-text models by AA-WER, its word error rate index. Nemotron 3.5 Transcribe ties for first among open-weight models at 2.8% AA-WER, with about 4B active parameters versus 24B for the model it ties. On AA-AgentTalk, the held-out voice-agent speech set that makes up 50% of the AA-WER index, Transcribe scores 1.8% WER, versus 2.3% for the next-best open-weight model. Transcribe pairs its speech encoder with a hybrid Mamba–Transformer mixture-of-experts language model, so only about 4B of its 30B parameters are active per token. That puts it on
Artificial Analysis
’s open-weight Pareto frontier of accuracy versus active parameters. On AA’s all-model chart, it ranks ahead of several widely used proprietary speech APIs.
Figure 2.
Leading AA accuracy
at about one-sixth the active parameters: Nemotron 3.5 Transcribe achieves 2.80% AA-WER with approximately 4B active parameters.
Speaker attribution across languages and overlap.
Sortformer speaker cues reach the language model with the acoustic features, so Transcribe can tag each turn during generation instead of relying solely on a later step to attach speakers to words.
David AI DAI-ASR-I18N Leaderboard.
On
David AI’s DAI-ASR-I18N combined transcription-and-speaker-attribution track
, Transcribe ranks first among evaluated open-weight models and second overall. On the benchmark’s diarization track, which scores who spoke when across 21 languages, it has the lowest diarization error rate of the 14 systems tested, slightly ahead of NVIDIA’s dedicated
Nemotron 3 Diarization
model.
Figure 3. NVIDIA models hold the top two spots on
David AI’s multilingual diarization leaderboard
: Nemotron 3.5 Transcribe posts the lowest overall diarization error rate (DER), 18.26% across 21 languages, followed by
Nemotron 3 Diarization
at 18.38%. DER measures speaker-time errors; lower is better.
VoiceArena Diarization-Bench.
On
VoiceArena’s English full-session benchmark
, Transcribe posts the lowest concatenated minimum-permutation WER (cpWER) of 14 systems and ranks first in both in-person and online settings. It also drops the fewest words: deletions are 8.32% of reference words, versus a median of about 31%.
Figure 4. NVIDIA models hold the top two spots in
VoiceArena’s 14-system comparison
: Nemotron 3.5 Transcribe leads at 32.4% cpWER, followed by NVIDIA Multitalker Parakeet with Nemotron 3 Diarization at 34.2%. Diarization-Bench v1 covers English full sessions, overlapping speech and 2–8 speakers. cpWER counts word errors after matching speaker labels; lower is better.
More evaluations.
Ocular AI’s Converse-STT evaluation ranks Transcribe the top open model. Josh Talks’
Voice of India
leaderboard reports Transcribe’s results across Indian languages.
High-throughput transcription.
In benchmarking, Transcribe processed 100 hours of audio in under three minutes on one NVIDIA RTX PRO 6000 Blackwell Server Edition GPU, using the forthcoming NVFP4 quantized version. Results were measured on 30-second clips at high concurrency.
Serve the available checkpoint with
vLLM
today. Local deployment with
NeMo-Speech.cpp
is coming soon alongside the quantized versions. Transcribe is built for recorded audio, not live streaming.
Specialized recordings can still call for adaptation to domain vocabulary and transcript conventions. Granary v2 and NeMo Speech fine-tuning address that, starting with the data behind Transcribe.
Granary v2: The open data curation pipeline behind Transcribe
A promptable speech model requires training data with unambiguous formatting targets.
Granary v2
is part of the
Nemotron speech collection
on Hugging Face and
ModelScope
. Built with
NVIDIA NeMo Curator
, its reusable pipeline prepared multilingual speech used in Nemotron 3.5 Transcribe’s training, producing aligned transcript variants, task labels, and inspectable quality metadata. The public manifest covers 463,062 hours across 48 languages and 16 source corpora, up from 25 languages in
Granary v1
. These figures describe the dataset release, not Transcribe’s full training mixture or its sampling weights.
Granary v2 generates three transcript forms for each recording (Table 1), the same verbatim and clean styles developers can request from Transcribe with a prompt. Beyond transcription, the pipeline produces short audio captions, code-switching restoration of loanwords, speech-grounded Q&A pairs, contextual ASR biasing terms, and translations with automatic quality scores.

Table 1. Granary v2 training targets for the same utterance.
The pipeline is organized into four reusable stages:
1. Audio Preparation (Metadata):
Segments raw or long-form audio, tracks speakers across the full recording, and tags acoustic events and language. Granary v2’s sources were already segmented, so this release skipped this stage.
2. Transcription (ASR):
Routes each language to primary and recovery ASR models, falling back when the primary fails a hallucination check. Human reference transcripts help preserve trusted spellings while adding spoken forms and disfluencies.
3. Task Label Generation (Text):
Derives transcript variants, then checks character rate, hallucination patterns, and model or human-reference agreement. Only accepted records receive contextual-ASR terms and translations.
4. High Fidelity (HiFi):
Filters out segments that are noisy, clipped, or contain multiple speakers, keeping a smaller set of high-quality recordings for uses beyond ASR. For the VoxPopuli dataset, it reduced 354k hours to 111k hours across 22 European languages.
Figure 6. Granary v2 data curation pipeline, following one sample from raw audio through the Metadata, ASR, and Text stages to a training example.
Developers can run the
NeMo Curator pipeline
with Ray and
NVIDIA Dynamo
backends on their own recordings or authorized public corpora, or build on the
Granary v2 public manifests
. The manifests include the three transcript forms as tn_raw, itn_raw, and itn_clean, the labels described above, entity hints, derived instruction pairs, provenance, and a per-record quality flag. Download source audio separately under each corpus’s original license, and follow the release’s published terms.
Adapt recognition to the vocabulary that matters
Start with a development-set prompt that specifies language, script, and transcript format. In the case study below, naming English and the Latin alphabet in the prompt cut full-benchmark WER from 30.8% to 23.8%. For domain errors that remain, the NeMo Speech fine-tuning workflow pairs representative speech with explicit written targets.
The
NeMo Speech medical ASR case study
shows this progression on
Eka Care’s open benchmark
of recordings from Indian doctors and medical students, which has 3,619 clips and no designated training split. The study builds adaptation data from generated medical text and public medicine catalogs, then combines approximately 153 hours of synthetic speech, 29 hours of accented English from Common Voice, and 63 hours of medical recordings from MultiMed.
Figure 7. On the full test set of Eka Care’s Indian medical speech benchmark, a better prompt cuts WER from 30.8% to 23.8%, and fine-tuning brings it to 11.8%, about 62% fewer transcription errors than the model out of the box. The full set includes the 855 tuning clips used to choose the prompt and checkpoints; the held-out results below are the cleaner test.
Synthetic generation separates the written target from its spoken rendering: “HbA1c” is the label, while “H B A one C” is sent to the synthesizer. Multiple TTS voices broaden the audio; real recordings add accents and recording conditions. Training text is filtered for exact matches and shared eight-word sequences with benchmark references.
As with Granary v2’s explicit targets, training examples vary digits, unit spacing, company-name expansion, and brand-name hyphens, with instructions specifying the required convention. Some prompts include term lists with near-miss distractors, so the model learns to use a spelling only when the audio supports it. The final system uses one fixed convention prompt and one model pass, without retrieval or transcript post-processing.
The recipe trains the speech encoder and projection and uses LoRA to adapt the language model. Two runs use different data mixtures; after adapter merging, selected checkpoints are uniformly averaged into one final model. Checkpoint selection uses decoded development-set results, rather than training loss alone. The full adaptation, from text generation through evaluation, took about 14 GPU-hours on one NVIDIA GB300.
Domain gains, measured on held-out speakers
The study splits the benchmark by speaker into 855 tuning clips, used to choose the prompt and checkpoints, and 2,764 held-out clips, decoded once per final system. Using Eka Care’s
KARMA scoring pipeline
, fine-tuning cuts held-out WER from 22.44% for the best-prompt baseline to 12.17%, a 45.8% relative reduction and the clearest evidence that the gains generalize to new speakers. Keyword WER falls from 9.2% to 6.5%, and semantic WER from 10.0% to 7.6%. On the same held-out speakers and scorer, the adapted model’s 12.17% WER beats an open medical-specialist model (13.79%) and a widely used general-purpose ASR model (14.92%).
On general English, LibriSpeech test-clean WER rises slightly, from 1.54% to 1.69%. The medical specialist still leads on exact matches for brand-name drugs and diagnostics; the study points to real recordings of clinicians saying brand names as the next step. For your own domain, keep at least 100 real, labeled clips for checkpoint selection, and evaluate the entity types your application depends on alongside general-speech retention.
The case study includes commands to reproduce each step. The
fine-tuning tutorials
cover recipes, resource requirements, and tools for training, export, and evaluation, including new-language and code-switching ASR. The accompanying
agent skill
lets a coding agent run the workflow, from baseline selection and data checks through training validation, adapter merging, and evaluation.
ModelScope also enables developers to fine-tune Nemotron 3.5 Transcribe through its
ms-swift framework
for specialized multimodal applications.

‘Light therapy without remortgaging the house’: the best LED face masks – tested
Guardian
www.theguardian.com

They claim to reduce fine lines, blemishes and redness – but which stand up to scrutiny? After consulting dermatologists and putting them to the test, we have crowned a brand new number one • The best anti-ageing creams, serums and treatments LED face masks are booming in popularity – despite being ...
L
ED face masks are booming in popularity – despite being one of the most expensive at-home beauty products to hit the market. They claim to reduce the appearance of fine lines, stop spots and calm redness, with some even combining different types of light to enhance the benefits.
However, it’s wise to be sceptical about new treatments that are costly and non-invasive, and to do your research before you buy. With this in mind, I interviewed doctors and dermatologists to find out whether these light therapy devices work.
They’re not a miracle cure for deep-set wrinkles, but experts say the best light therapy masks can promote collagen production, improve elasticity and help smooth skin with sustained use. And while it may seem like a new technology,
research from the 1990s
shows the efficacy of light therapy in wound healing, acne treatment and skin rejuvenation.
Red and infrared light are safe to use on all skin types, but be warned that blue light can worsen hyperpigmentation on darker skin tones.
I’ve tested some of the most popular devices on the market – including infrared masks – to narrow down my favourite LED face masks for treating a range of skin concerns.
I’ve been reviewing health and beauty tech for the past five years. During this time I’ve witnessed many beauty fads come and go. Naturally tight-fisted and a sceptic, I was initially struck by the cost of these masks. How on earth can an elaborate LED light strip set you back more than £300?
But after testing multiple light therapy masks, I’ve come to understand the technology behind them – and, sadly, you won’t be able to engineer your own light therapy system with a costume mask and a set of LED string lights.
I don’t have many fine lines or wrinkles to test on, but I can comment on how blue-light treatment affects acne because I’ve suffered from it since I was a teenager – despite my mum’s assurances that it would clear up after puberty. The experts I spoke to agreed on the efficacy of red and infrared light for anti-ageing.
Are LED face masks worth it?
Light therapy masks are fantastic additions to a skincare routine, helping to smooth, firm and reduce blemishes. Since I started using one almost two years ago, my skin is calmer, less prone to redness, and has a more even tone.
However, LED masks can be expensive, and if you’re not disciplined enough to use one regularly, you won’t see results. Before you splash up to £500, keep in mind that light therapy masks are most effective when paired with a
good skincare routine
. It’s crucial to make sure skin is properly cleansed before treatment and protected from sun damage afterwards.
If you don’t already have a
skincare
routine nailed down, don’t buy a light therapy mask just yet. Consider starting out using a gentle cleanser and moisturiser, with an
SPF
for daytime. You could also incorporate targeted skincare serums, such as
retinol
and
vitamin C
, to help firm and brighten the skin without the need for an expensive light therapy mask.
How I tested
‘I tested the fit, comfort levels and usability of 18 of the most popular light therapy masks.’

Since LED treatments take a while to show visible results, it’s difficult to test multiple light therapy masks at once (at least, without spending a few years testing them), so I enlisted the help of dermatologists who were familiar with light therapy treatments long before they were commercially available.
I spoke to Dr Barbara Kubicka, an expert in aesthetic medicine; Dr Derrick Phillips, a consultant dermatologist and spokesperson for the British Skin Foundation; and aesthetic doctor Dr Priya Verma, an authority on the science of skin ageing.
I asked these experts to identify which light therapy mask features – such as bulb quality and quantity, light wavelength and treatment time – matter the most, to inform my choices. They also outlined the suitability of light therapy for different skin types and its associated risks.
Armed with their advice, I tested the fit, comfort levels and usability of 18 of the most popular light therapy masks and other targeted LED devices. Getting hands on with the masks allowed me to pinpoint any of the key features the experts recommended, as well as features I found helpful as a consumer.
I’ve been using a light therapy mask regularly for almost two years, so I can identify a good mask from a bad one. My tests also included monitoring results after four nightly sessions, with the obvious caveat that only very minimal changes could be observed after such a short-term treatment. I then tested my favourite masks over several months, too, helping me to verify any unique treatment claims – as well as giving me plenty of opportunities to scare my boyfriend by sneaking up on him wearing each one.
Only masks that use the brightest, flicker-free bulbs, fit comfortably and are easy to use made the final cut. After testing, I returned the masks sourced for this article to the manufacturers. Where that wasn’t possible, I cleaned the masks and donated them to the
Redbridge Reach Out
service, which supports anyone experiencing domestic abuse.
‘My skin looked glowier and healthier than usual after my six weeks of testing’: our tester’s verdict on the CurrentBody Series 3.
Photograph: Sarah Matthews/The Guardian
Best LED mask overall:
CurrentBody Series 3
CurrentBody
Series 3
from
£499.99
What we love
Fully customisable; particularly good for anti-ageing
What we don’t love
Its high price and bulky controller
Most LED masks come with a few settings that treat the entire face for one skin concern. But many of us don’t have uniform faces: a dark spot here, a blemish there, fine lines elsewhere. One flat treatment might help with overall skin condition, but it can’t pinpoint a specific skin concern exactly where you need it.
The CurrentBody Series 3 is the only mask I’ve found that allows users to completely customise their treatments. It’s also the only mask I’ve tested that offers penetrating deep near-infrared lights across the whole face, making it the new LED mask to beat.
Why we love it
The mask has 125 light points spread over the face, each of which can produce six light wavelengths: green for pigmentation, yellow for redness, blue for blemishes, red for wrinkles, near-infrared for firming and near-infrared to support deeper skin renewal. I was able to select exactly which light (or combination of lights) I wanted to shine from each light point on the face using the CurrentBody app. Since I primarily get spots on my chin, I targeted these breakouts while sticking to anti-ageing treatments elsewhere and threw in some yellow light to tackle redness in my cheeks.
I usually hate apps for beauty tech, but I found it refreshingly simple to use, without any ads or pop-ups. Tailoring the light colours I wanted was as easy as using a colouring book, and the app then automatically programmed the light levels to ensure the right dosage within the 10-minute treatment time. It paired seamlessly with the mask to run my custom treatment – the whole process took less than five minutes.
In terms of results, the redness in my cheeks had faded, my chin appeared to clear quickly after a particularly brutal hormonal breakout, and the rest of my skin looked glowier and healthier than usual after my six weeks of testing. And, if you aren’t fussed about personalising your treatments, the mask has four pre-programmed options for anti-ageing, blemishes, redness and dark spots.
It’s a shame that …
it’s so expensive and, to accommodate its wider range of treatment options, its controller has a touchscreen that’s frustratingly easy to knock to pause or stop your treatment midway.

If you want to try light therapy without remortgaging the house, the Silk’n LED face mask 100 is a good choice. It has 100 LED bulbs with good facial coverage, is comfortable to wear, and offers a good range of light colours. It doesn’t have near-infrared lights like the pricier options, but it covers the basics at a decent price.
Why we love it
This mask offers four colour modes: red, blue, yellow and purple. Red light helps stimulate collagen to reduce the appearance of fine lines, while blue light helps to soothe breakouts. The purple light comes from mixing the aforementioned blue and red lights, combining the effects of both to boost the skin’s overall evenness.
Although less widely researched (and with limited clinical evidence to suggest efficacy), the experts I spoke to said the yellow-light treatment could help improve hydration levels in the skin. I didn’t notice a huge hydration hit when testing this feature, so if your skin is crying out for hydration, I recommend using the other light settings alongside a
hydrating serum
.
Each colour can be selected individually for a 10-minute targeted session, or you can select automatic mode, which cycles through the colours over 15 minutes to provide all the benefits at once.
I found the Silk’n light therapy mask simple to use and comfortable to wear. Its flexible silicone build didn’t feel quite as sturdy as more expensive options, but I didn’t really notice this when using the mask. The built-in eye shields weren’t as bulky as others, but they still blocked out the light and protected my eyes well.
The automatic mode left my skin feeling completely comfortable, with a slightly glowier finish than usual – just what I’d expect from an entry-level mask such as this one.
It’s a shame that …
there’s no timer and it has fewer than a seventh of the bulbs of the CurrentBody, with no near-infrared light treatment for effective collagen stimulation deeper in the skin. This means it’s better for light-touch anti-ageing, and for soothing, acne-busting blue-light treatments.

What we love

What we don’t love
Mask steams up a little inside and there’s no countdown
Most face masks look a little creepy, but the TheraFace Mask Glo takes this to another level. It focuses on providing full facial coverage over the mouth and nose area, and its glowing red eyes might be the last thing you’d want to see staring back at you from across a dark room, but the results are fantastic. And, if its appearance gives you a shock, you can switch on its massage function to calm back down.
Why we love it
The first thing to note about the TheraFace Mask Glo is its sturdy build, which feels surprisingly lightweight on the face thanks to the adjustable back and top straps and large silicone-padded eye area. These distribute the weight across the brow bone and undereyes and around the head so that everything feels comfortable, no matter the position you’re in. There’s also a removable inner eye insert that blocks light from your eyes without blocking light from reaching the undereye area, where it can help reduce the appearance of fine lines.
The mask has 168 light points that emit the three most well-researched light wavelengths: blue, red and near-infrared light. These can be selected as individual settings, or you can kick back while the automatic 12-minute treatment cycles through everything you need to target fine lines, firmness and breakout-causing bacteria. Alongside this, I found the steady vibration massage, located in the mask’s straps, oddly relaxing. Its aim is to gently stimulate the scalp, increase circulation and relieve tension, but if you find the massage uncomfortable, it can be switched off.
Another selling point is its wireless controls. It has two buttons, which scroll through the three treatment modes and the vibration massage functions. These are intuitive, and I liked that I could roam around freely instead of carrying around a wired controller for the 12-minute treatment.
It’s a shame that …
its lack of mouth and nose holes means the mask steams up by the end of a session. Also, it doesn’t have a countdown, so the 12-minute treatment can feel long.

Best LED device for acne-prone skin:
Lustre Solo
What we love
Targeted blemish treatments in a portable package
What we don’t love
Leech-like appearance and extra running cost
Acne can be a real pain, and many cosmetic treatments that target it leave skin feeling irritated, dry and flaky. These nifty adhesive LED patches from Lustre use blue light, which the company claims reduces breakout-causing bacteria.
Why we love it
Each Solo patch has 15 pure blue LEDs at the
proven wavelength for treating acne
, 415nm. The patches cover a targeted area of skin about 2.5 x 5cm, which is perfect for treating problem areas such as the chin, cheeks and forehead. Since they’re rechargeable and far smaller than a typical LED face mask, they’re highly portable, making it easy to stick to a treatment routine.
I found the targeted treatments very effective for minimising breakouts in my chin area – somewhere I often struggle with spots. Continued treatments saw fewer breakouts and faster healing.
The patches come with a supply of double-sided adhesive to fix each one to your skin, allowing you to move around freely during treatment. This also means, unlike typical light therapy masks, they can be safely fixed anywhere on the body.
If you’re worried that the adhesive will feel uncomfortable or be tricky to remove from breakouts, don’t be. The patches are so lightweight that the adhesive doesn’t need to be very strong. I found it easy and comfortable to peel off the patches after the recommended 20-minute treatment time.
It’s a shame that …
you need to buy the sticky patches when they run out. These cost
£18 for a pack of 60
, or 30p each. They also look a bit like leeches – only you can decide if that’s more palatable than the Hannibal Lecter look of the full-face LED masks.

What we don’t love
Imperfect eye shielding and fiddly straps
Most LED masks recommend 10- to 15-minute daily treatments for best results. If you’re short on time but still want to invest in a reliable face mask, the SpectraLite FaceWare Pro is my recommendation. It offers anti-ageing, anti-blemish and a combination of both treatments, with daily sessions taking just three minutes. That’s something even the most time-poor can commit to, and consistency is what gets you results.
Why we love it
This is the most comfortable hard-shell LED mask I’ve tested. It’s lined with a thick, flexible but sturdy-feeling layer of silicone that provides cushioning on every part of the face. During use, it evenly distributed the mask’s weight across my nose, forehead and cheekbones, no matter if I was lying flat or sitting up.
I was surprised by this, since the mask’s battery is built into the forehead rather than in a separate remote – the Lustre Renew Pro Facewear reviewed below has a similar design but is less comfortable to wear. The SpectraLite FaceWare Pro perfects the hands-free design, making it comfortable, breathable and easy to control with one button. Mercifully, there’s no useless app.
In the mask, you’ll find 100 red LEDs (including red, near-infrared and amber) and 62 blue LEDs distributed over 80 light points on the face. These have been strategically positioned so that the blue lights cover the nose, forehead, chin and lower cheeks (oily areas where acne-causing bacteria thrive), while the red light is more evenly dispersed. There are separate red anti-ageing and blue acne-fighting modes, but I used the combination mode in my tests and was pleasantly surprised by how well the mask reduced blemishes while easing redness across my face.
The keen-eyed among you may notice that the three-minute treatments are significantly shorter than the 10- to 20-minute treatment times recommended by the experts I spoke with. However, according to the brand, its clinical studies have seen results from red-light treatments within 10 weeks of daily use, and blue light within two weeks. In my weeks testing this mask, my skin did appear smoother, brighter and clearer. If you’re hunting for a quick, comfortable mask without fancy features, such as app connectivity and additional colour options, this is a strong bet.
It’s a shame that …
its straps aren’t the easiest to adjust, and the mask doesn’t shield the eyes as effectively as others. If you have sensitive eyes, opt for something that has built-in eye guards instead. It also doesn’t have a remote or a countdown, but the treatments are so quick that this isn’t much of an issue.

What we don’t love
Confusing settings and a finicky fit
For a long time, deep near-infrared light was reserved for the most expensive LED masks. So, when the Silk’n LED face mask Pro launched in October 2025, with 20 deep near-infrared lights included on the forehead and around the eyes and mouth, I was keen to try it. Even more so when I learned of its comparatively reasonable price.
While its treatments aren’t quite as streamlined as the CurrentBody Series 3 above, it offers a range of treatments and light wavelengths at half the cost. So, if you want a great value mask, or travel often and need a mask that packs down well, this is my recommendation.
Why we love it
This mask packs in seven treatment options, which combine five wavelengths of light. A few of these treatments felt a little surplus to requirements, such as the stand-alone red- or amber-light treatments – I can’t fathom why you wouldn’t want to use the setting that includes near-infrared and deep near-infrared as well. But the treatments I used most often were effective. The red-light settings had a good calming effect on my skin, and when I paired this with a few minutes of the blue light, I noticed my blemishes reduced and healed faster.
All the controls for this mask are built into a small battery pack, which magnetically attaches to the front of the mask. While this means you don’t get to see a countdown or a screen displaying setting time, there are no wires to mess around with. The battery is incredibly lightweight and can last through a whole week of treatments without recharging.
I also liked this mask’s flexible straps and its adjustable chin strap. The Silk’n Pro packs down completely flat or folds into its carry case, not much larger than a box of tissues, for travel. This is incredibly useful if you’re frequently away from home.
It’s a shame that …
the chin strap hangs away from the chin slightly, and I found the eye guards pressed hard into the bridge of my nose. I also found it confusing to select different treatments because the various configurations of red-toned light were indistinguishable from each other.

What we love
Intuitive to use; targeted treatments; undereye cooling
What we don’t love
Heavy mask that presses into the undereyes when reclining
The Shark CryoGlow is the only LED face mask I’ve tested that offers built-in undereye cooling alongside targeted light therapy. It has three different wavelengths of light: blue, red and near-infrared, arranged into presets for “better ageing”, “blemish repair” and “skin sustain”. I found the lights incredibly bright during my tests – although for safety, they automatically dim when you remove the mask from your face – but I was happy with how the mask shielded my eyes.
During every treatment, you can choose to switch on the cooling undereye patches, which aim to de-puff and soothe your skin. The cooling can also be used on its own, without the LEDs. There are three levels, the coolest of which felt startlingly cold at first but did a great job of calming down my eyes on a particularly bad hay fever day. Likewise, the blemish mode did a brilliant job of calming spots and redness with sustained use. I also liked using the skin sustain mode for a quick pick-me-up to brighten skin before a night out.
It didn’t make the final cut because …
it’s noticeably heavier than its silicone competitors, and other plastic masks that don’t have undereye cooling. The mask fits comfortably when you’re sitting up, but when lying down, the metal cooling patches pressed into the delicate area under my eyes. Similarly, the location of the cooling patches means the light can’t access fine lines under the eyes. Another unfortunate side-effect of the cooling is the whirring noise it makes – inaudible from far away, but pretty noisy when pressed on to your face. I think most people would be better off with the TheraFace Mask Glo.

If the multiple settings in the
Series 3 mask
above offer more versatility than you’ll use, and you’re mainly hoping to achieve anti-ageing results, choose this mask. The CurrentBody Series 2 mask was my top choice on this page for a long time, and it’s still an incredibly comfortable, effective mask that offers red, near-infrared and deep near-infrared lights.
The deep near-infrared lights penetrate deeper than the other two types of light, CurrentBody claims. This leads to more effective treatment where it’s needed most – the deep near-infrared bulbs are positioned under the eyes and around the lips to better target areas where ageing is more pronounced.
I used this mask for three months, and was pleased to notice my skin looking calmer and more even-toned than usual, with less undereye inflammation. As it’s a red-light mask, it didn’t have much effect on my acne, but it did help to reduce redness.
It didn’t make the final cut because …
as someone with temperamental skin, I think spending the extra £100 on the multiuse Series 3 is worth it. This mask offers only one treatment setting, and there isn’t a screen displaying the treatment time. Neither is a dealbreaker, but it’s nice to be able to choose different treatments, and at this price, I’d expect a countdown timer.

Less close contact with the chin area
The neck and decollete are often the first places to show signs of ageing, as the skin is thinner in those areas. Consequently, expensive neck light therapy masks have started to flood the market – but rather than requiring additional expensive kit, this Stylpro mask can be adjusted to treat multiple areas including the back, neck, scalp and face.
It’s incredibly versatile. It has red, deep red, near-infrared and blue light, which all combine into 11 programs to target different areas of concern on your body. The remote control has a huge screen, making it easy to select the desired programme and treatment zone. This also displays the mask’s battery life and treatment time.
In my tests, the straps did a great job of keeping the flexible silicone mask in place. Its eye shields were also brilliant at blocking out light, and the snap fasteners made it easy to adjust the mask between different treatment areas. To treat the back and neck area, I found you needed to lie down or sit up very straight to prevent it from slipping, but it was great to have the versatility.
It didn’t make the final cut because …
when used in face mode, the mask hangs a few inches away from the chin area, which means the light has less direct contact there. Its eye guards also tended to gently pinch the bridge of my nose.

Most light treatment masks have wired controls. That doesn’t mean you need to remain tethered to a single spot, but it does mean there’s a remote that you have to carry around with you. This mask from Lustre, on the other hand, is controlled via a mobile app. The two preset treatments can also be operated using a button on the mask.
It has two programmes, called Energise and Revitalise, and uses blue, red and near-infrared light. Unusually, you can choose which kind of light you want to use in four areas of your face: forehead, eyes, nose, and cheeks and chin. In my tests, I liked being able to treat spots on my chin with blue light while using red light on the rest of my face.
It didn’t make the final cut because …
it’s not very comfortable. Since the battery is on the mask itself, it’s a little top heavy, and the eye protectors don’t do a great job of shielding your eyes.
Also, I hate having lots of apps on my phone – it’s up to you whether the wireless freedom is worth the app installation.

If your main area of concern is the lip area, you might not need to buy a full mask. The Silk’n LumiLips has 30 LEDs

The only other masks in this roundup offering deep near-infrared light are more than £250, which gives you a good idea of how much value it offers.
The mask has two modes, both of which use dark red, near-infrared and deep near-infrared light. The red-light mode claims to promote lip volume and firmness
,
while the second mode adds in amber light to reduce pigmentation and redness. I love that the mask requires only a five-minute daily treatment, making its less-than-comfortable mouthpiece slightly more bearable.
It didn’t make the final cut because …
it’s built like an adult pacifier and feels like one too. You have to bite down on the mouthpiece to keep it in place, which is far less comfortable than just wearing a mask with a strap around your head.

Peep Club heated eye wand LED+
Peep Club
Heated eye wand LED+
from
£85
What we love
Dedicated, soothing treatment for eye area
LED face masks usually arrive with guards to protect your eyes from the light, which means they neglect to treat the delicate skin around the eyes – an area particularly prone to fine lines, wrinkles and discoloration.
The Peep Club heated eye wand is a nifty little gadget that was designed in collaboration with optometrists, primarily as a hot compress to help with dry, tired eyes. The LED+ model includes a small LED light, which glows red to reduce fine lines and amber to decrease the visible blood vessels that cause dark circles. There’s also green light for soothing inflammation, although the evidence around green light is shaky.
During testing, I found it soothed my irritated eyes after long days staring at a screen. The amber light setting seemed to reduce my dark circles, too, after a few weeks of consistent use. As recommended, I used it with the
Peep Club coconut eye balm
to give the wand a bit of slip, which avoided irritating the delicate skin under my eyes.
It didn’t make the final cut because …
it’s not as convenient to use as a dedicated mask, since you have to glide it over the skin. Its LED light is small, so you need to dedicate a lot of time to treatment to get the best results. While I love using the coconut eye balm and a 40ml tub lasts a long time, it leaves an oily slip on the skin after treatment, and the need for this extra running cost may be off-putting.

The rest of the test
I’ve tested many more LED devices than can fit on this page, and while I don’t usually draw attention to bad products, I came across so many poorly designed models that I feel it necessary to shed light on the LED masks that overpromise and underdeliver.
First, we have the
Revolution Pro Miracle LED face mask
, which costs just £59.99 at full price. Believe me, I wanted this mask to be a winner, but its solid plastic structure, with no eye shielding or padding, made it so wildly uncomfortable to wear that it was an almost instant write-off. The straps are another problem; they come together around the bottom part of your head, causing the mask to constantly fall. It also seems built for very small faces, so it constantly slipped down my face, pinching my nose and making it difficult to breathe properly – even if I used it without the straps and lay flat during treatment. Throw in fewer LED bulbs than average and dim lights, and this mask is impossible to recommend.
A high price tag doesn’t guarantee how good the mask is either, as evidenced by the
Foreo FAQ 202 LED mask
, £719 at full price. Its light weight and comfort level, along with an array of treatment options via its app-based controls, meant it impressed initially. However, its silicone design felt incredibly flimsy, and after a week of use, it had already started peeling away from the central battery pack.
This might be forgivable if Foreo offered a full warranty and repair service. There’s a
two-year warranty
covering defects and faulty workmanship, but this does not cover “cosmetic deterioration caused by fair wear and tear, or damage caused by accident, misuse or neglect”. To access accidental damage coverage, you have to pay Foreo’s £9.99/month subscription. Even if you’re happy to risk it, at the time of testing in June 2026, you still had to shell out £4.99/month to access the mask’s full suite of preset treatments. Add to this the scale of advertising you’re bombarded with in the app – some of it unskippable. When you consider its price, this brazen money-grubbing leaves a very bad taste.
Through testing this family of devices, I had also been hoping to find an undereye brightening LED patch to usurp the Peep Club wand, which requires constant movement across the eye area. I had hoped that the
Lustre GoGlow
brightening and de-puffing patches would fit the bill. They come in a handy headphone-like charging case and have a clever wireless design. However, when positioned under the eyes as advertised, the light was incredibly bright, which made it tricky to see. The sticky pads, although small, were uncomfortable to remove, and my skin was left feeling irritated for a day afterwards. The search for the perfect undereye LED patch continues …
What you need to know
Red light is just one of several LED wavelengths used to target different skin concerns.

What is LED therapy, and how does it work?
“LED (light-emitting diode) therapy is a non-invasive treatment that uses specific wavelengths of light to stimulate various cellular processes in the skin,” says aesthetic medicine expert Kubicka. “Depending on the colour or wavelength, LED light can target inflammation, promote collagen production, accelerate healing and even kill bacteria.”
Light therapy is a great addition to your skincare routine – for me, it’s helped reduce breakouts, improve healing and reduce the appearance of my acne scars. LED face masks are quick, gentle and non-invasive, and suitable for most skin types (although as mentioned above, blue light can worsen hyperpigmentation on darker skin tones, according to the experts I spoke with). The masks are effective and foolproof to use, and the daily treatments also force you to take a little time for yourself – perfect for a morning pick-me-up or an evening wind-down.
Does red light help with anti-ageing?
“Red-light therapy can reduce the appearance of fine lines and wrinkles through a process called photobiomodulation,” says consultant dermatologist Phillips. “It energises mitochondria, which are the batteries of the cells, powering the production of collagen and elastin by fibroblasts, the factories of the skin.”
Elastin and collagen are “the building blocks of firm, youthful skin”, says Kubicka. Stimulating the production of these molecules can “improve skin density, elasticity and overall smoothness” as long as you complete treatments regularly.
I don’t have many fine lines or wrinkles, but I’m keen to avoid more by using red-light therapy for “preventive ageing”. However, “most of the clinical evidence
focuses on treating visible signs of ageing or repairing damaged skin, rather than long-term prevention in younger skin”, as aesthetic doctor Verma explains.
Still, Verma reassured me my efforts wouldn’t be in vain. “Using LED light consistently and appropriately may help support overall skin health […] especially when combined with sun protection and a good skincare routine.”
What different colours of light therapy are available?
Several colours are available, with each wavelength said to target a different skin concern. These colours correlate to the visible light spectrum, and each can have a different effect on the skin.
Red light has a wavelength of between 630 and 700nm and is the most widely known form of light therapy, loved for its non-invasive potential anti-ageing benefits. Near-infrared light above 700nm “penetrates the skin more deeply to support tissue repair and reduce inflammation”, according to Kubicka. Blue-light therapy (415nm), on the other hand, has been proven to target acne-causing bacteria, leading to a reduction in breakouts over time. Kubicka also says blue light can help regulate oil production – another common problem for those with acne.
The effects of some types of light on the skin are better researched than others.
Near-infrared
,
red light
and
blue light
are backed by scientific studies that identify the biological processes that each type of light triggers in the body.
Meanwhile, research into green and yellow light is more limited. One study questions the
efficacy of yellow-light
therapy and claims that a previous study may have been influenced by the placebo effect. Similarly, a study on
green light therapy
suggests that more research is needed to provide a solid recommendation for use as an anti-ageing treatment.
How and when would you recommend using light therapy?
The “how” is simple: always use light therapy masks on freshly washed, dry skin, before applying serums and creams. This will give the light the most direct access to the skin.
Despite what some instruction manuals advise, don’t jump into daily treatments straight away – you may end up with slightly irritated skin. Start by introducing treatments two to three times a week, and monitoring the impact on your skin. If you don’t notice any sensitivity, you can incorporate more treatments, if permitted by the manufacturer’s guidelines.
Once your skin is used to the treatment, “home devices should be used three to five times a week, for 10-20 minutes a session,” says Phillips. But treatment times vary between devices, so always follow the manufacturer’s instructions, and don’t expect instant results. If you’re hoping to reduce breakouts, you should “see a reduction in redness and the frequency of acne breakouts within two to four weeks”. Those using red light for anti-ageing benefits will need to wait a little longer: “It typically takes six to eight weeks to see visible changes.”
Is light therapy safe for all skin tones?
“LED light therapy is generally very safe when used correctly,” says Verma. This is because, unlike laser hair removal, it only uses low-level, non-thermal light. “The most common side effects are mild and temporary, such as slight redness, dryness or irritation.”
“People with known photosensitive disorders or taking medications that make them more sensitive to light (eg certain antibiotics) should consult their doctor,” says Phillips. He also warns that those with darker skin tones should exercise caution when using blue light, since “some blue wavelengths have been associated with hyperpigmentation”. The Lustre Solo patches recommended above offer exclusively blue light, but the other masks in this roundup have blue-light-free settings if you do find that it causes sensitivity.
How much should I spend on an LED therapy mask?
There are hundreds of light therapy masks available at different prices, but the quality varies wildly. You may see results from a budget-friendly mask, such as the
Silk’n LED face mask 100
reviewed above, but spending more will generally get you a larger quantity of bulbs that offer a greater range of wavelengths. You’re also more likely to get a mask with a better fit and coverage.
The best mask for you will depend on your skin concerns and budget. Those hoping to invest in a mask with anti-acne properties will be able to spend less, since blue light is more widely available, but if you’re looking for the best anti-ageing deep near-infrared light therapy, you will need to part with more cash.
High-end red-light therapy masks can cost upwards of £500; if you spend that much, just make sure you use it regularly, or you won’t see results.
How to clean an LED face mask
Cleaning instructions for LED masks will differ slightly from brand to brand, based on the different materials used. As a general rule, you want to steer clear of using chemical or alcohol-based cleansers since these can damage a mask’s delicate silicone and padded components. Always check the instructions for your specific mask before jumping into cleaning.
The usual best practice is to use a non-abrasive cloth, such as
microfibre
, dampened with water to wipe down your mask after every use. Try not to use too much water and never submerge the mask, as doing so will damage the electrical components. Always make sure your mask is unplugged and switched off before cleaning, and wait for the mask to dry completely before storing, charging or switching it on.

f your social media algorithms have clocked that you’re into video games, something strange will have happened in the past few weeks. Your feed, like mine, will have been full of clips of streamers playing bizarre
mashups of popular video games
. Skyrim in Minecraft. Halo, except the main character is Mario. Skate 2 in Call of Duty maps. A flood of professional-looking fan-coded game mods that are mildly interesting to look at for 30 seconds, but ultimately inconsequential. Would I download a mod that lets me play Wii Bowling inside a zombie shooter? No, but I am very interested in where they came from.
Of course, the answer – or at least, most of the answer – is AI. After a week of researching this (thanks especially to Replay Mode on YouTube for
this informative video
, which set me down this track) I now understand that these mashup mods are not just AI-generated videos, but AI-assisted coding. Basically, as of a few weeks ago, Anthropic’s Claude has become extremely good at decompiling video game code. Games are written by humans in readable code and then compiled into binary 1s and 0s that the PC or console running it can read; decompiling is the reversal of that process, revealing a game’s source code, which humans can then edit and mess around with for fun. This used to be an extremely laborious process. But now it is not, because humans aren’t doing much of it any more.
Claude is now able to spit out a game’s source code from its compiled version overnight. Tell it to combine two games and it will help with that, too. There is not zero human involvement: from what I understand, the best of these mashups have needed significant human tweaking. But this has completely transformed video game modding because you now need drastically less time and computing knowledge to be able to pull off massive projects. It now takes an evening rather than months of work.

As a person with zero coding knowledge, I was curious about how easy this was to do. I asked Claude how I’d go about making my own mashup, I picked one relatively obscure game and one extremely popular one, just to be annoying. Claude gave me comprehensive instructions and background on some modding and emulation tools, which was super interesting but ultimately of no use to me, because I had no idea what I was doing. So I just asked it if it could build me this in a browser.
Four minutes later, it spat out a rubbish but playable game, with further instructions on how I could get the visual assets from the source games so that Claude could incorporate them for me and host it as a local file to avoid copyright issues. In half an hour, I had made something that’s still rubbish, but good enough for a 15-second TikTok. Except I haven’t made anything at all – the machine has done it for me. I
still
have no idea what I’m doing.
This probably doesn’t seem that different from people using AI to create fake images of Jesus shaking hands with Trump to post on Facebook – and it isn’t, really. But people who DO know what they’re doing have gone much further with this AI-assisted source-code bonanza. I have seen relatively recent games such as Zelda: Tears of the Kingdom running in web browsers. Github is full of open-source code for Steam-like game launchers that draw from all the emulated codebases available, essentially giving you a vast library of retro games for free. Most consequentially, PlayStation 5 emulation has made an enormous jump: you can now run almost any PS5 game on a PC. For free.
Much of this is obviously extremely illegal. Regarding the PlayStation 5 situation, I have seen a lot of angry videos describing this as a justified response to Sony’s abandonment of physical games: if you can’t buy a game anyway, how can you steal it? Nintendo Switch and Switch 2 emulation has also become astonishingly easy, thanks to AI-assisted launchers and mod hubs with beautifully clean interfaces. Speaking as a former prodigious teenage pirate (I wasn’t always so technically illiterate), you used to have to accumulate some secret knowledge to avail yourself of this stuff. That is no longer the case.
There are enormous consequences here for any video game publisher that would rather not
have all of their game’s code freely available online for people to do what they want with. And that, presumably, is all video game publishers. AI is a technology built on the theft of creative work, as all writers and artists know – but up until now, it has not affected corporations to the same extent. Now that it does, will AI companies finally be forced to pump the brakes?

My house has been completely overtaken by
Nintendo Switch Sports Resort
, which brings motion-controlled sports from skateboarding to thumb-wrestling to your living room, alongside more normal options such as tennis, golf and bowling. This is obviously a game in the Wii Sports lineage, and it fully embraces that landmark game’s accessible, fun-first philosophy, while also building on it to keep your interest going, from competitive leagues and online play to peaceful plane and jetski tours around the titular resort. My kids are obsessed with it. And because they’re up and moving, I felt perfectly fine about letting them play it for four straight hours while we were trapped in the house by Storm Boelo over the weekend.

The boring answer to this is, of course,
Microsoft Flight Simulator
, which is 100% geographically accurate because it draws on satellite images of the entire Earth. I also played a strange experimental game last year called
Prologue: Go Wayback!
, which a team in Amsterdam made – it procedurally generates accurate northern European wilderness for you to survive in, based on an impressively complex algorithm.
Plenty of games have created architecturally accurate cities – all of the Assassin’s Creeds, Tom Clancy’s The Division, Yakuza/Like a Dragon and of course Grand Theft Auto – but fewer have made geographically accurate places that don’t have a volcanic lava-land in troublingly close proximity to a jungle. Forza Horizon’s versions of Mexico, Japan and the UK feel
accurate, but aren’t. Apparently
Kingdom Come: Deliverance
is based on a geographically accurate recreation of 15th-century Bohemia, which doesn’t surprise me at all given that game’s devotion to historical believability.

Guessing the Name: MacBook Studio?
Daring Fireball
www.macrumors.com
2026-10-28 10:58:45
Joe Rossignol, MacRumors:
A teaser video shared by Apple CEO John Ternus today hints at
a potential name for the rumored MacBook models with touch-enabled
OLED displays: MacBook Studio. [...]

reporters and content creators at an ex...
The video shows an Apple logo being projected onto a wall against a city skyline, and perhaps that wall is a movie studio. Apple is expected to show off the new MacBooks to selected tech reporters and content creators at
an experience in Los Angeles at 10 a.m. Pacific Time today
, and that is the home of Hollywood movie studios after all.
If this theory proves to be accurate, then Apple would offer both a Mac Studio desktop computer and a MacBook Studio laptop, plus the Studio Display. Apple would likely position the MacBook Studio as being aimed at creators, and it would surely promote its
recently-updated Apple Creator Studio suite of apps
alongside the announcement today.
This is obviously all just some last-minute speculation for fun — we
did the same with iPhone Duo
. The new models could stick with MacBook Pro branding, and the long-rumored MacBook Ultra name still remains a possibility too.
Bonus theory: What if the teaser hints at the
glowing Apple logo returning
to the MacBook's lid? We truly might be getting ahead of ourselves now.
Shortly after the iPhone Duo launched, a few users reported hinge issues that were causing cracks in the inner display. Apple has now responded to the reports in a statement to MacRumors, saying a small number of units are affected.
The response to iPhone Duo from early users has been incredibly positive, and we are seeing exciting things from developers who are rapidly updating their apps...

A Tesla Semi caught fire on Interstate 880 in Hayward, California, on Tuesday evening, and there was no crash. The electric truck’s lithium-ion battery burned long enough to keep the southbound freeway closed for about 10 hours.
The driver got out unhurt. But a Class 8 electric truck catching fire on its own, in traffic, is something Tesla and its growing list of Semi customers need to explain.
What happened on I-880
The fire broke out at around 5:35 p.m. PT in the southbound lanes near Route 92. CHP Hayward then closed I-880 in both directions, citing “the potential risk of hazardous chemical smoke,” and posted these photos from the scene:
🚨 TRAFFIC ALERT – I-880 FULL CLOSURE 🚨
A Tesla semi-truck has caught fire on I-880, resulting in a complete shutdown of both northbound and southbound lanes due to the potential risk of hazardous chemical smoke.
pic.twitter.com/O01z32nxpZ
The driver told officers the truck caught fire and that they didn’t know why. No other vehicles were involved.
Northbound reopened Tuesday night. Southbound took much longer. CHP initially warned that the battery could burn for 15 to 18 hours, but crews beat that estimate, and
CHP Hayward posted
that all lanes were open at around 3:30 a.m. Wednesday.
The CHP photos show firefighters laying foam around the burned-out tractor, with the front of a Premier Trailer Leasing trailer charred behind it. The truck’s operator hasn’t been identified, and Tesla, which doesn’t have a press office, hasn’t commented. The cause is under investigation.
The second Semi fire to close a California interstate
We’ve been here before. In August 2024, a Tesla-operated Semi
caught fire on I-80 near Emigrant Gap
while driving from Livermore to Tesla’s facility in Sparks, Nevada. At the time, no crash was reported. The
NTSB later found
the truck had left the road on a curve, hit a delineator post and a tree, and its battery ignited after the impact. Firefighters used about 50,000 gallons of water, and the lanes stayed closed for up to 15 hours.
Hayward is different. Without a crash, the focus shifts to the truck itself: the battery pack, the high-voltage system, the drive units, or something as ordinary as a tire or brake fire that spread.
And the timing isn’t great for Tesla. The company only
started volume production of the Semi in Nevada
this year, after nearly a decade of delays. WattEV ordered 370 Semis in May, mostly for drayage at the Port of Oakland, just a few miles up I-880 from where Tuesday’s truck burned. In September, Tesla was also named lead supplier on a 2,500-truck ZET SCALE order.
Electrek’s Take
First, some perspective, because this fire is going to get used as an anti-EV talking point. Truck fires are common. According to
NFPA data
, US fire departments responded to an average of 15,462 large-truck fires per year between 2018 and 2022. That’s about 42 a day, in a fleet that’s overwhelmingly diesel. Mechanical failure was a factor in 44% of them, and only about 2% were tied to a collision.
The same goes for cars. NFPA and DOT data put the US average at one vehicle fire for every 17 million miles traveled, and combustion vehicles make up the vast majority of that fleet. Tesla
claims
one fire per 140 million miles for its own vehicles. That’s Tesla’s number, but independent data, like
government figures we’ve covered before
, points the same way: gas vehicles catch fire more often than EVs.
But that doesn’t get the Semi off the hook. Diesel fires happen across millions of trucks. Tesla doesn’t disclose Semi deliveries, but PepsiCo, its launch customer, was up to about 86 trucks in 2024, and volume production only started a few months ago. With a fleet that small, one fire with no crash is a big data point. It’s also the second Semi fire to shut down a California interstate in about two years.
So we need the cause. If a tire, a brake, or the trailer caught fire and it spread to the tractor, that’s a regular trucking problem. If the pack went into thermal runaway on its own, Tesla needs to find out why before tens of thousands of these trucks hit the road, and fire departments need a better plan than letting a loaded truck burn on a freeway for half the night.
The NTSB investigated the last one. It should look at this one too, and Tesla should publish what it finds. Will it?
Electric trucks and cars are only as clean as the electricity charging them. If you’re driving an EV, powering it with home solar can cut your fuel costs to nearly zero. With electricity rates up almost 10% last year and expected to keep climbing, going solar is one of the best ways to protect yourself against rising costs. And with lease and PPA options, you can do it with zero upfront cost and start saving immediately. If you want to find the best deal, check out

Microsoft urges Entra ID admins to migrate users to passkeys
Bleeping Computer
www.bleepingcomputer.com

Microsoft again asked Entra ID administrators to migrate users to phishing-resistant methods to avoid sign-in disruptions before it retires SMS and voice authentication in February 2027.
This retirement process applies only to Microsoft Entra ID workforce tenant authentication scenarios and not to Azure AD B2C or Microsoft Entra External ID customer identity scenarios.
Before Microsoft retires SMS and voice authentication, admins should ensure all users in their organizations use a phishing-resistant method, since they will no longer be able to use them to complete multifactor authentication and log in to their accounts.
Admins can choose from passkeys, QR code authentication, FIDO2 security keys, and other Entra ID-supported sign-in methods.
"Microsoft-provided SMS and voice authentication will retire starting February 1, 2027. Complete your migration before rollout begins to avoid interrupting users' sign-in experience," Microsoft said in a
Microsoft 365 Message Center update
on Tuesday.
"SMS and voice are vulnerable to phishing and SIM-swap attacks. Microsoft recommends passkeys for stronger, phishing-resistant protection. You can also migrate to another supported authentication method or retain SMS and voice by configuring a customer-managed telecom provider (CYOT) through the Microsoft Security Store."
Organizations that must use phone-based authentication have to configure third-party telecom providers through the Microsoft Security Store.
Passkeys now the default Entra ID auth method
In July, Microsoft announced that passkeys will start rolling out as the default authentication experience for the Entra ID enterprise identity service starting in September.
"As the rollout reaches each organization, users enabled for SMS or voice authentication will automatically be enabled for passkeys, and the next time they perform multifactor authentication, they'll be prompted to register a passkey,"
Microsoft said
.
"Following this transition, on February 1, 2027, Microsoft will retire Microsoft-provided telecom delivery for SMS and voice authentication and will no longer offer SMS and voice as a native Microsoft Entra capability."
Microsoft also
retired SMS first-factor sign-in
for Microsoft Entra ID Free tenants in August due to phishing, fraud, and account compromise risks, and stopped enabling it for newly created tenants.
Detailed guidance on deploying and managing phishing-resistant passwordless authentication in Entra ID is available on this
dedicated Microsoft documentation page

You've probably heard, at this point, about the big changes coming to Meta's AI scraping terms for business accounts. Nieman Lab had that scoop, and since then, small businesses, journalists, and artists using Meta products like Instagram have been raising the alarm. But if you're in the EU or UK, you might be in luck and can object to that use of your data, as some users have pointed out.

Earlier this month, Meta updated its commercial terms of use for business accounts to allow it to “use any content from such domains, web pages, or URLs to provide, develop, improve, research, train, and maintain the integrity of” Meta’s products.
Many artists and small business owners that rely on Instagram and Facebook are livid at Meta granting itself permission to use their content, including from websites simply connected to their Meta accounts, to train AI. But for users in the United Kingdom and European Union, for now, there’s a way to object.
Meta
buried this change
in its
Commercial Terms
, and
Nieman Lab first reported
on the change. The update was originally set to go into effect on October 30, but following backlash, Meta changed the effective date to November 20. Adding to the confusion, Meta then removed the word “train” from a list of allowed use cases,
Nieman Lab reported
, and limited those uses to “advertising and business products,” where previously it said that data would be used for all Meta products. Those terms still allow Meta plenty of leeway for scraping users’ data to develop its products, however.
Several users based in the UK and EU have explained how to object on Instagram. On mobile: by clicking the three lines on their account, going to the privacy center, and clicking “object,” which goes to a form that asks users to write why they are objecting to their data being used. They received an email from Meta saying their objections were approved.

The scrapes were likely automated. But that is exactly the problem: as far as our logs show, nobody checked. A crawler working for a company whose platform tens of millions of children use was pointed at an adult site, and it took explicit models without telling them apart from anything else,”

In a form of architecture so ancient, CNC machines may seem a little out of place. However, when one considers that the medieval builders were always on the forefront of the technology of their day, it no longer seems so strange. To build Gothic today, it must become a reality, not a romantic idea locked up forever in one’s head.
(The Carmelite Monks spend their allotted work time on construction. See their
Horarium
here.)
CNC carving of a Gothic pinnacle by the Carmelite Monks
CNC machines and robots have unlocked the ability to relatively quickly carve the intense details of a Gothic church. Ornate pieces that used to take months for a skilled carver, now can be accomplished in a matter of days. Instead of cutting out the beauty, using the excuse that it takes too long, thus doesn’t fit into the budget, modern technology can be used to make true Gothic in all its beauty a reality again today.
The use of modern technologies in stone carving unlock the potential of modern youth. Though they may be untrained in the use of a hammer and chisel, young men and women have grown up in a world of computers. The skills they possess can now be channeled towards a higher end, the building of a church for the glory of God.
CNC Programing of a Gothic pinnacle by a Carmelite Monk
What is a CNC machine
CNC stands for “computer numerically controlled”, where a computer, through a series of XYZ coordinates, controls the movements of a machine. The first CNC was invented for the manufacturing of airplane parts. Stone cutting CNC machines are a relatively new invention.
Stone carving CNC machines typically use diamond tipped blades and milling bits, not water or laser, to carve the stone. The diamonds, harder than the stone, grind away at the stone and wear it away. The water is simply to keep the diamond tool from heating up from the friction and to wash away the stone sludge created by the carving process.
CNC stone cutting blade and bits used by the Carmelite Monks
Normally the stone carving CNC machines used for sculptures and foliage have 5 axes, being able to move left and right, up and down, front and back, and rotate their heads in two different ways. The machines interpolate these multiple axes in order to carve the stone. “Interpolate” means to work together, and an axis is one direction of motion. So, the machines can move left, and down, and rotate their heads all at the same time to reach into a small area or leave a particular finish on the stone. Sometimes they will even have a 6th axis, typically a lathe or a turntable, for carving tall stones such as pinnacles or statues. The lathe interpolates with the other axes, carefully positioning itself to allow the CNC machine to reach each area of the stone. CNC machines can also carve stone unattended, sometimes for long periods at a time and overnight. This means 40 hours, a typical week of work, is less than 2 days for a CNC, a significant time savings!
CNC lathe and spindle at work carving stone for Carmelite Monks
Prussiani CNC machines
The Carmelite Monks use CNC machines from Prussiani Engineering, a stone CNC manufacturer based out of Bergamo, Italy. Italians have always been at the forefront of stone carving, and it is no different with modern technology. With Prussiani’s machines the monks can carve levels of detail previously reserved to the hand carving of highly skilled craftsmen. With the mindset “where there’s a will, there’s a way” and careful programming the machines’ capabilities are practically limitless and have the ability to carve unprecedented 3D reliefs.
The Prussiani machines also have a reputation of being indestructible, a reputation proven in the battlefield of stone carving. Stone is an incalcitrant material, and it takes robust machines to subdue it; no small task! Here’s a little story to illustrate. For the first time, a few months after we started carving stone, we left our first CNC machine running overnight on several 7 foot long window sills. We woke to a shocking surprise the following morning. The huge stones, weighing several hundred pounds each, had been thrown about as if a tornado had ripped through the machine. Stones were snapped and shattered, the fragments scattered about the inside of the CNC milling area. After the shock settled, we proceeded to analyze what had happened. It turns out there was a mistake in the particular batch of code the machine had read and followed that night. At the very end of each window sill, after it had completely finished carving, the code told the CNC machine to repeatedly pound down into the top of the sill, almost as if it was a giant fist. The stones didn’t stand a chance, but that same machine is still carving stones to this day, almost a decade later.
The Carving Process
The process of carving stone with a CNC is a digital workflow. The ornate pieces covered in foliage, the statues, the gargoyles, and many other distinct Gothic elements begin with the artist, the head carver. He sculpts the various flowers and leaves using a 3d modeling program in a process much similar to molding a ball of clay. It still requires a great deal of artistic talent, but there is a major advantage to this work in a computer, the Undo button! The artist can experiment with an almost infinite number of designs to find the one most suited to the space. And with the ability to visualize the pieces in a full model of the church, there is no longer any guesswork as to what the finished building will look like.
The Brother artist carving in mudbox for the Carmelite Monks Gothic
Once the artist has finished a particular sculpture it is passed on to the actual stone carvers, the CNC programmers. The programmers take the 3d model into a CAM program, which stands for computer aided machining, and create the toolpaths that the CNC machine will use to carve the actual stones. Utilizing a large arsenal of tooling and methods they gradually carve the stone down to the finished piece. They do their best to transform the stone block they start with to as close a resemblance of the artist’s model as possible, similar to the way stone carvers have historically used a pointing machine to transfer measurements from a plaster model into stone. At the same time they have to juggle a wide array of concerns, from which tools to use depending on speed and finish, to how to keep the stone from moving, to avoiding collisions between the cnc and the stone, or even other stones they might be carving at the same time. This is a lot to keep track of, but if done well, it will quickly bear fruit. It is extremely rewarding to see the keystrokes and mouse clicks of a computer turn into not only a finished product, but an ornately carved part of a Gothic church, a place God will be loved for centuries to come.
Finally, once all of that Gcode (the programming language of a CNC machine) is ready, it is handed over to the sawyers, who operate the CNC machines themselves, as well as the various other saws that prepare the stone blocks for carving. The sawyers are the “boots on the ground” guys and keep a clear line of communication open with the programmers to ensure that everything runs smoothly. They carefully follow the layouts and tooling lists the programmers prepare for each piece as they set up the stones for carving, set reference points so the machines can locate each stone, and monitor it as it carves. They are constantly keeping a watchful eye to ensure that everything goes smoothly. There is a symbiotic relationship between the sawyers and the programmers as the work of each is essential to the successful completion of each stone.
The Monk Sawyers setting up a table to be Carved for the CNC
The sawyers also operate the wire saws and bridge saws, cutting each stone to either be carved into something more ornate, or to go straight into the wall. The wire saw, a simpler type of 2 axis cnc itself, can cut simple profiles, including any straight piece, such as columns and the straight parts of window surrounds. The sawyer, using the wire saw, will take a large slab of stone and sometimes cut even 20 or 30 different smaller stones out of it; looking similar to pieces from a cookie cutter. This frees up the 5 axis CNC machines to focus on the more ornate pieces, and is also significantly faster.
The monk Wire sawyer puts in plastic shims to support the cut pieces. On the right is the finished product of the wire saw awaiting the denesting of the profiled stones
There are many different facets to the art and science of stone carving today and only a few have been touched on here. Pneumatic chisels and hand carving certainly have a valuable role to play, as well as a multitude of other methods not discussed here. The learning curve to dive into such a work is indeed daunting, the workload intimidating, but the fruit of it will stand for centuries to come.

An architectural comparison of Obsidian Canvas and Heptabase
At first glance, the
Obsidian Canvas vs. Heptabase
debate looks like a choice between two similar spatial note-taking tools. Both give you an infinite 2D canvas, both let you arrange notes side by side, and both let you draw arrows between ideas.
Under the hood, however, their data architectures are fundamentally opposite.
The short answer:
Obsidian Canvas
stores visual arrangements inside individual
.canvas
files using the open
JSON Canvas
format. In
Heptabase
, whiteboards are non-owning visual views over a central card library.
In practice, this means
a line drawn on an Obsidian Canvas creates no link between notes in your vault, while a line drawn on a Heptabase whiteboard creates a connection both cards remember.
In short: Obsidian’s connections are portable across external tools but unindexed in your vault’s graph; Heptabase’s connections are indexed across your cards but locked into its proprietary ecosystem.
If you are trying to decide whether to build your long-term knowledge workflow in Obsidian Canvas or invest in a dedicated spatial tool like Heptabase, looking at UI features won’t give you the answer. You have to look at how each tool models files, cards, and context.
Architectural Breakdown: Obsidian Canvas vs. Heptabase
Embeds Markdown files or local text cards inside an open
JSON Canvas
file
Maps global cards as live views across multiple whiteboards simultaneously
What Connection Lines Mean
Visual coordinates stored in the board file; portable across tools, but unindexed in the vault graph
Relational connections surfaced in the Card Info panel; indexed in the workspace, but locked into the app
Context Awareness
Canvas-bound:
Context lives in the canvas file, not in the note itself
Context-aware:
Every card tracks all whiteboards it belongs to and all connected cards
Portability vs. Indexing
Portable, but unindexed:
The
.canvas
file uses open JSON Canvas, but notes remain unaware of connections
Indexed, but proprietary:
Connections compound across boards, but cannot be exported as an open interactive graph

Obsidian Canvas: A Visual Layer Stored Inside a Single File
Obsidian is built on a local-first philosophy: your knowledge base is a folder of plain-text Markdown files. Obsidian chose the file as its atomic unit. That choice is what makes a vault portable and durable—and it is also why a canvas can only be another file, with nowhere to store a connection except inside itself.
1. Spatial Organization: Embedding Files into a Single Canvas
When you create an Obsidian Canvas, you create a standalone
.canvas
file (stored on disk as JSON).
This creates an immediate architectural split:
Cards created inside the canvas stay inside that file.
If you type out ten quick thought cards directly on a canvas, those cards exist only inside that
.canvas
file. They do not appear as independent notes in your vault unless you manually convert them into separate Markdown files one by one.
External notes are embedded views.
When you drag an existing
.md
file onto a canvas, Obsidian renders an editable viewport into that file. However, the canvas is simply referencing the file’s path from the outside.
2. Connecting Ideas: Visual Lines vs. Real Graph Links
In a spatial workspace, the lines connecting notes often carry as much meaning as the notes themselves.
In Obsidian Canvas, the arrows you draw on a board are stored as visual coordinate data inside that specific
.canvas
file. They do not register as Markdown links or
[[wikilinks]]
, and they do not appear in Obsidian’s global Graph View. If you draw an arrow from
Note A
to
Note B
on a canvas, the core link engine records no link between the two notes.
This architectural limitation is a frequent discussion point among users. In an
Obsidian community forum thread
introducing the
Canvas Links
plugin, one user noted:
“visual connections in the canvas are not actual links and so don’t show up in graph view.”
While community plugins can bridge embeds and show which canvas references a file, the core canvas lines remain localized visual data rather than relational graph links.
3. Context Awareness: Context Lives in the Canvas, Not in the Note
Because Obsidian’s architecture is strictly file-centric, Markdown files and
.canvas
files are structurally separated.
If a Markdown file is embedded across multiple canvases, it is simply being viewed from the outside. The file itself stores no metadata about its visual placement:
When you open the note in your regular editor, it does not display which canvases currently contain it.
It does not know what neighboring cards sit next to it on any canvas.
It cannot see what arrow labels or connections point to it.
The moment you leave the
.canvas
file, that spatial context stays behind in the canvas file, leaving the note as an isolated piece of linear text.
The Verdict on Obsidian Canvas
Obsidian Canvas is best suited for visual brainstorming, process flowcharts, and system mapping. Because connections remain within the canvas file, it is less suited for atomic notes that need to accumulate links across many boards over time.
Heptabase: A Context-Aware Thinking Workbench
Heptabase approaches spatial note-taking from the opposite architectural perspective. Instead of treating the whiteboard as a container file that embeds independent documents, Heptabase separates
what a note is
from
where a note is viewed
.
1. Spatial Organization: Whiteboards as Non-Owning Views
In Heptabase, the atomic unit of the system is the card rather than the file.
“Whiteboards do not own cards. All cards belong to the Card Library. The same card can be placed on multiple whiteboards at the same time.”
Because whiteboards are non-owning visual views over a central library, placing a card on a whiteboard does not isolate or nest it. You can place the exact same card across multiple whiteboards simultaneously without duplicating content or breaking sync. An update made to a card on one board immediately reflects everywhere else that card appears.
2. Connecting Ideas: Whiteboard Connections in the Card Info Panel
When you draw a connection line between two cards on a Heptabase whiteboard, the relationship is reflected directly in the workspace outside the board itself:
Open
Card A’s
Card Info panel, and it lists
Card B
under its connected cards, noting the whiteboard where the arrow was drawn.
Open
Card B’s
Card Info panel, and it displays the incoming connection from
Card A
.
Clicking a connection entry in either card jumps you directly to that exact spatial coordinate on the whiteboard.
While inline
@mentions
in card text handle linear cross-references, whiteboard lines provide a dedicated spatial linking layer that cards track wherever they are opened.
3. Content Architecture: Cards That Preserve Context
Because cards are global entities, they retain their relational history across the entire workspace.
Opening a card’s
Card Info Panel
reveals its complete spatial context:
Every whiteboard that currently contains this card.
Every card that connects into it or out of it across all boards.
A direct jump link back to the card’s exact position on any referenced whiteboard.
When you examine a card outside of any board, its visual and relational context remains accessible.
The Architectural Trade-Off of Heptabase: Portability vs. Integration
This deep contextual integration comes with a clear structural trade-off:
data portability.
Obsidian Canvas saves spatial arrangements as standalone
.canvas
files adhering to the open
JSON Canvas
specification—meaning any external script or third-party tool can parse your boards.
Heptabase, by contrast, manages cards, connections, and whiteboard coordinates within its proprietary system. While Heptabase allows you to export your cards into standard Markdown files, your whiteboards export as static image files or linear card lists. The interactive visual lines and relational graph connecting those cards cannot be exported into an open visual format like JSON Canvas. You trade file durability and vendor-neutral portability for an integrated spatial workspace.
The Verdict on Heptabase
Heptabase functions well as a cumulative thinking workbench for visual researchers. Its global card architecture allows relationships established on whiteboards to compound across your workspace over time. However, adopting Heptabase requires committing to a specialized, proprietary ecosystem rather than relying on standard plain-text files.
Beyond 2D Whiteboards: When Spatial Brainstorming Meets Rigorous Writing
Understanding the architectural difference between
Obsidian Canvas
(a visual layer stored inside an individual file) and
Heptabase
(global cards mapped across non-owning views) clarifies how each tool approaches spatial organization.
Yet for researchers and writers whose primary goal is producing structured arguments rather than visual maps, 2D whiteboards themselves encounter natural limits:
2D arrows lack explicit logical semantics:
On a whiteboard, an arrow between Card A and Card B indicates connection, but not logic. It does not formally specify whether an idea
supports
a claim,
refutes
an assumption, or serves as a prerequisite
condition
.
Translation friction from 2D space to linear prose:
Whiteboards arrange thoughts across spatial coordinates, whereas essays, reports, and memos are read sequentially. Turning a sprawling 2D canvas into a cohesive manuscript still forces you to manually flatten the spatial arrangement back into linear paragraphs, where the underlying logical skeleton often gets lost.
A Third Approach: Explicit Proposition Trees
Whiteboards optimize for visual brainstorming; documents optimize for sequential reading. Bridging the gap between messy exploration and rigorous writing requires modeling the logical dependencies of ideas—claims, evidence, and counterarguments—rather than 2D coordinates.

Frequently Asked Questions
Can I export my Heptabase whiteboards and cards into Obsidian?
You can export the text content of your Heptabase cards into standard Markdown files and import them directly into an Obsidian vault. However, whiteboards export either as static images or linear lists. The interactive visual lines and spatial coordinates connecting those cards cannot be exported into an open visual format like
JSON Canvas
, meaning spatial relational graphs cannot be migrated seamlessly between the two tools.
Do connection lines in Obsidian Canvas count as backlinks in the Graph View?
No. Connection lines and arrows drawn on an Obsidian Canvas are stored strictly as layout data inside that individual
.canvas
JSON file. They do not write
[[wikilinks]]
into the connected Markdown notes, nor do they appear in Obsidian’s global Graph View or backlink panels.
Yes and no. You can embed the same
.md
note file across multiple
.canvas
files, and any text edits made to that note will stay in sync. However, the connections, neighboring cards, and arrow labels on each canvas remain isolated to their respective
.canvas
files; an individual note has no native awareness of which canvases embed it or how it is linked across them.
Is Obsidian Canvas fully offline and local-first compared to Heptabase?
Yes. Obsidian Canvas operates entirely on local plain text and local JSON files without requiring a user account or network connection. Heptabase supports client-side offline editing, but its unified card library and cross-device sync are built around a proprietary cloud database architecture.

I will be using x86 naming throughout this post, but the concepts apply to other architectures too. Basic familiarity with SIMD and x86 assembly is assumed;
uops.info
and Intel’s
intrinsics guide
explain any instruction you don’t recognize.
A lot of SIMD code, particularly in the graphics programming space, use vec3/vec4 types all over the place. The issue is that this typically doesn’t scale beyond the SSE instruction set. In this post I want to share how you can “transpose” those vectors into lanes to scale your math operations beyond just those typical 4 component XMM registers, and have the efficiency scale up to 8 or 16 wide vectors (or maybe 32 wide vectors, if we ever get them).
To avoid the use of intrinsics, I’ll use Clang’s vector extensions (
ext_vector_type
) to represent the operations, since they’re easier to read and the logic can easily be reimplemented with intrinsics.
We’re going to look at a simple case on how to do N dot products at the same time (where N is the architecture’s SIMD width), and a typical CPU frustum culler as a more advanced example.
Frustum culling should ideally be done on a GPU, but that’s beyond this article
All measurements below have been made on a Ryzen 7 5800 (Zen 3) CPU, with Clang 23.1.0 targeting Windows x64. The compile flags are
-std=c++20 -O3 -ffast-math
, along with
-march=x86-64-v3
(AVX2, FMA and BMI2) for the 8 lane code, and
-march=x86-64-v2
(SSE4.2) for the 4 lane equivalents, for anyone who wants to follow along. Every number is the best of 12 runs, and varies by about 2% from run to run. All of the code is
on Compiler Explorer
, with one pane for each instruction set.
-ffast-math
lets the compiler assume no value is NaN or infinite. If your bounding boxes can have NaN or infinite positions or sizes, don’t use the flag: the culler’s comparisons may then give any answer for those boxes.
The basic example
Let’s take a look at what one dot product typically compiles to:
using vec3 =float__attribute__((ext_vector_type(3)));using vec4 =float__attribute__((ext_vector_type(4)));using vec8 =float__attribute__((ext_vector_type(8)));floatdot(vec3 a, vec3 b){returna.x*b.x+a.y*b.y+a.z*b.z;}floatdot(vec4 a, vec4 b){returna.x*b.x+a.y*b.y+a.z*b.z+a.w*b.w;}
Not bad. And surprisingly, a vec3 dot costs the same as a vec4 dot. Regardless, the problem is that if we want to do multiple dot products, the cost scales linearly.
A tip for Windows:
the default x64 calling convention passes any vector argument by pointer, which is where the
vmovaps
and the memory operand above come from. Marking the function
__vectorcall
(or compiling with
/Gv
in clang-cl and MSVC) passes vectors in registers instead, as the System V ABI on Linux already does.
/Gv
leaves member functions out, so a member function that takes vectors by value needs
__vectorcall
either way. With it, the dot product compiles to:
Why doesn’t the compiler do this for us? Because it would have to change the data layout. A compiler will happily vectorize a loop over an array of floats, but turning your array of
vec4
s into four arrays of floats changes what every other piece of code reading that memory sees, so no compiler will reorder and transpose your data for you. That part is up to us.
A more complex example
Doing many dot products is cool and all, but it doesn’t have much of a practical use on its own. Let’s try applying the same trick to an average frustum culler.
The math for those who are unfamiliar with it: A (camera) frustum consists of six planes with their normals pointing outwards. A plane is stored as
(n, d)
: its unit normal
n
, and
d
, its offset along the normal, chosen so that
dot(n, p) + d
is the signed distance from a point
p
to the plane. A point is in front of the plane when that distance is positive, and if a box is entirely in front of any one plane, we can cull it.
A box is stored as its center and its half extent: the offset from the center to a corner along each axis, so its corners are
center ± halfExtent
. A simple way to cull it is to check if all eight corners are in front of a plane.
Sample code, where each plane is a plain
vec4
with the normal in
xyz
and the offset along the normal in
w
:
struct Box { vec3 center; vec3 halfExtent;};vec3 abs(vec3 v){return__builtin_elementwise_abs(v);}booloutsidePlane(vec4 plane,const Box&box){for(int c =0; c <8; c++){ vec3 corner =box.center+box.halfExtent* vec3{ c &1?1.0f:-1.0f, c &2?1.0f:-1.0f, c &4?1.0f:-1.0f};if(dot(plane.xyz, corner)+plane.w<0.0f){returnfalse;}}returntrue;}voidcullNaive(uint64_t*results,const vec4*planes,const Box*boxes,uint32_tcount){for(uint32_t i =0; i < count; i++){bool visible =true;for(uint32_t p =0; p <6; p++){if(outsidePlane(planes[p],boxes[i])){ visible =false;break;}}constuint32_t shift = i %64;results[i /64]=(results[i /64]&~(uint64_t(1)<< shift))|(uint64_t(visible)<< shift);}}
The cost is 13.4 ns per box. We can do better.
A simple optimization
You can achieve the same result by testing only the corner with the lowest signed distance:
center - sign(n) * e
, one step against the normal on every axis. If even that corner is in front of the plane, the whole box is:
The second term is the distance from the center to that corner, measured along the normal, so one test replaces eight:
voidcullNearestCorner(uint64_t*results,const vec4*planes,const Box*boxes,uint32_tcount){for(uint32_t i =0; i < count; i++){bool visible =true;for(uint32_t p =0; p <6; p++){constfloat distance =dot(planes[p].xyz,boxes[i].center)-dot(abs(planes[p].xyz),boxes[i].halfExtent)+planes[p].w;if(distance >=0.0f){ visible =false;break;}}constuint32_t shift = i %64;results[i /64]=(results[i /64]&~(uint64_t(1)<< shift))|(uint64_t(visible)<< shift);}}
That’s 3.0 ns per box, so we’re already four times faster than the basic implementation.
The branch predictor
Going from 10,000 boxes to 100,000, the same loop suddenly takes 12.7 ns per box. That’s only 3 MB of data, read front to back, so memory isn’t the problem. To see what is, I timed a 1,000-box scene and cycled through a different number of scenes between runs:
Scenes
ns per box
1
3.0
16
3.0
18
5.2
20
7.3
32
11.3
200
13.3
200 identical copies
3.0
The last two rows touch the same amount of memory. The difference is that in the last one every scene is a copy, so the early outs come in the same order every time. The CPU predicts each branch before it knows the answer, and Zen 3 can memorize the early outs of about 16,000 boxes. So if your benchmark culls the same small scene in a loop, you’re mostly benchmarking the branch predictor. Here, it made the nearest-corner test look 4.4× faster than it is on new data.
Culling multiple boxes at the same time
Now that our benchmark measures the culler rather than the branch predictor, back to the point of this post: making full use of the available SIMD width. We can just use templates to make the same code work on any type T, so float, double, vecN all work.
template<typename T>struct Vec3Lanes { T x, y, z;};template<typename T>T dot(const Vec3Lanes<T>&a,const Vec3Lanes<T>&b){returna.x*b.x+a.y*b.y+a.z*b.z;}template<typename T>Vec3Lanes<T>cross(const Vec3Lanes<T>&a,const Vec3Lanes<T>&b){return{a.y*b.z-a.z*b.y,a.z*b.x-a.x*b.z,a.x*b.y-a.y*b.x};}
And then the boxes can be expanded similarly:
template<typename T>struct Box3Lanes { Vec3Lanes<T> center, halfExtent; T getMinSignedDistance(vec4 plane)const{const vec3 n =plane.xyz, a =abs(n);returnn.x*center.x-a.x*halfExtent.x+n.y*center.y-a.y*halfExtent.y+n.z*center.z-a.z*halfExtent.z+plane.w;}};
The boxes are stored in blocks of
Box3Lanes
, one box per lane, with the last block padded out. The number of lanes
W
is 8 with AVX2 and 4 with SSE, so the same code fills whatever register size we compile for:
#ifdef __AVX2__constexpruint32_t W =8;#elseconstexpruint32_t W =4;#endifusing floatW =float__attribute__((ext_vector_type(W)));using intW =int32_t__attribute__((ext_vector_type(W)));
A whole block can’t take the same early out, so the branch has to turn into a mask:
template<typename P>intW visibleMask(const Box3Lanes<floatW>&block,const P*planes){ intW visible =intW(-1);for(uint32_t p =0; p <6; p++){ visible &=block.getMinSignedDistance(planes[p])<0.0f;}return visible;}[[gnu::always_inline]]inlinevoidwriteLanes(uint64_t* results, intW visible,uint32_t first,uint32_t count){for(uint32_t lane =0; lane < W && first + lane < count; lane++){constuint32_t i = first + lane;constuint64_t held =visible[lane]&1;results[i /64]=(results[i /64]&~(uint64_t(1)<<(i %64)))|(held <<(i %64));}}voidcullLanes(uint64_t*results,const vec4*planes,const Box3Lanes<floatW>*blocks,uint32_tcount){for(uint32_t first =0; first < count; first += W){writeLanes(results,visibleMask(blocks[first / W], planes), first, count);}}
This runs at 1.24 ns per box with AVX2 and 2.87 ns with SSE. On AVX2 that’s 10× faster than the nearest-corner test on fresh data. The SSE number is disappointing, though. Against the nearest-corner test with a trained predictor it’s only 1.3× faster, which isn’t much to show for four lanes. So let’s look at the assembly.
The assembly in question
For one block of eight boxes against six planes, the math compiles to:
6 loads;
6
vmulps
and 30
vfmadd231ps
;
6
vcmpltps
and 5
vandps
to combine the masks.
Those 53 instructions are fine. The problem is that the whole loop is about 220.
Every block gets 30
vbroadcastss
, 12
vpermps
and 6
vandps
, and none of them have anything to do with the block. The compiler does this because six planes need 42 splats and AVX2 only has 16
ymm
registers. Its register allocator figures that recomputing a broadcast is cheaper than spilling it and loading it back. For a plain broadcast from memory that’s true, but it redoes the
abs
and the permutes too.
The results are written one bit at a time.
vpextrdr9d, xmm3, 3; take one lane out of the maskmovr15d, r10dandr15b, 56; the block's first bit within the wordmovebp, 8shlxrbp, rbp, r15andnrbp, rbp, r11; clear the lane's bitorr15b, 3; the lane's bit within the wordshlxr11, r9, r15; shift the lane to that bitorr11, rbpmovqword ptr [rcx + 8*rsi], r11; store the wordlear9, [rax - 4]cmpr9d, r10d; was that the last object?je .LBB12_11
That’s thirteen instructions per lane, about 100 per block, which is more than the math itself.
Splatting the planes once
So we do the splatting ourselves, once, before the loop, and keep the results in memory:
template<typename T>struct PlaneLanes { Vec3Lanes<T> normal, absNormal; T constant;};// Broadcasts each component of v into its own registerVec3Lanes<floatW>splat(vec3 v){return{floatW(v.x),floatW(v.y),floatW(v.z)};}PlaneLanes<floatW>splatPlane(vec4 plane){return{splat(plane.xyz),splat(abs(plane.xyz)),floatW(plane.w)};}voidcullLanesSplatOnce(uint64_t*results,const vec4*frustum,const Box3Lanes<floatW>*blocks,uint32_tcount){ PlaneLanes<floatW>planes[6];for(uint32_t p =0; p <6; p++)planes[p]=splatPlane(frustum[p]);for(uint32_t first =0; first < count; first += W){writeLanes(results,visibleMask(blocks[first / W], planes), first, count);}}
Box3Lanes
gets a second overload for the splatted planes:
T getMinSignedDistance(const PlaneLanes<T>&p)const{returndot(p.normal, center)-dot(p.absNormal, halfExtent)+p.constant;}
Now the compiler reads the planes straight from the stack as memory operands of the FMAs:
vfmadd231psymm3, ymm15, ymmword ptr [rsp + 1056]
That gets AVX2 down to 0.98 ns per box and SSE to 1.85 ns. SSE benefits more because its blocks only hold four boxes, so it was rebuilding the frustum twice as often.
Writing the block at once
The eight result bits of a block make up exactly one byte, so we can turn the mask into one bit per lane and store all eight at once. With SSE, two blocks of four share a byte, so each one writes its half:
using boolW =bool__attribute__((ext_vector_type(W)));voidwriteBlock(uint64_t*results, intW visible,uint32_tfirst){const boolW bits =__builtin_convertvector(visible, boolW); // one bit per laneuint8_t& byte =reinterpret_cast<uint8_t*>(results)[first /8];ifconstexpr(W ==8){ byte =__builtin_bit_cast(uint8_t, bits); // store all eight}else{constuint32_t shift = first %8; // two blocks of four share a byteconstuint8_t held =__builtin_bit_cast(uint8_t, bits)&0xF; byte =(byte &~(0xF<< shift))|(held << shift);}}voidcullLanesBlockWrite(uint64_t*results,const vec4*planes,const Box3Lanes<floatW>*blocks,uint32_tcount){uint32_t first =0;for(; first + W <= count; first += W){writeBlock(results,visibleMask(blocks[first / W], planes), first);}if(first < count){ // only the last block, if it isn't full, still goes lane by lanewriteLanes(results,visibleMask(blocks[first / W], planes), first, count);}}
The partial last block is handled after the loop rather than with a branch inside it. That matters more than it looks: when the mask is created in one basic block and turned into bits in another, Clang no longer knows every lane is either all ones or all zeros, and replaces the single
vmovmskps
with a chain of shuffles and packs.
The writeback now looks like this:
vmovmskpsr10d, ymm2; one bit per lanemovbyte ptr [rcx + rax], r10b; store all eight
With both changes in place, AVX2 takes 0.67 ns per box
1
and SSE 1.84 ns. The loop is down to about 95 straight-line instructions per block of eight, or about 3 cycles per box.
Results
All times are in nanoseconds per box, for 10,000 boxes. The numbers in brackets are for 100,000 boxes, which is too many for the branch predictor to memorize.
Splatting once helps both, SSE the most (1.55× on its own, against 1.27× on AVX2), while the block writeback alone does less (1.19× on AVX2, 1.07× on SSE). On AVX2 the two compound, since once the splats are gone, the bit-by-bit writeback is most of what’s left; together they make the one-box-per-lane version 1.85× faster. On SSE the writeback adds nothing once the planes are splatted, and the combination stays at 1.56×. From start to finish, the culler got about 20× faster, or 25× on data the branch predictor hadn’t seen before.
Conclusion
Most of the speedup comes from turning vectors into lanes. Eight dot products cost three instructions, and the early outs become masks. The less obvious part is that the straightforward SIMD version spent more instructions moving data around than on the actual math, and it took two more changes to get rid of that. Precompute whatever the compiler can’t keep in registers, and write the results a whole block at a time. You’ll run into the same two problems in any loop that tests lots of objects against a few shared values.
1
Only when the stack happens to be 32-byte aligned. Windows and Linux only guarantee 16 bytes, and Clang spills the splatted planes’
ymm
registers with unaligned stores rather than realigning the stack, so in some processes half of the reloads straddle a cache line, and the same loop takes 0.99 ns. Adding
__attribute__((force_align_arg_pointer))
to the function makes Clang realign the stack in its prologue, which gives 0.67 ns every time.
If You're In the UK or EU, Here's How to Object to Meta's AI Training
403 Media
www.404media.co
2026-10-28 10:18:35
In light of Meta's new terms that will allow it to scrape users' data for AI, people in the EU and UK have the option to "object" to certain uses of their information, for now....
Earlier this month, Meta updated its commercial terms of use for business accounts to allow it to “use any content from such domains, web pages, or URLs to provide, develop, improve, research, train, and maintain the integrity of” Meta’s products.
Many artists and small business owners that rely on Instagram and Facebook are livid at Meta granting itself permission to use their content, including from websites simply connected to their Meta accounts, to train AI. But for users in the United Kingdom and European Union, for now, there’s a way to object.
Meta
buried this change
in its
Commercial Terms
, and
Nieman Lab first reported
on the change. The update was originally set to go into effect on October 30, but following backlash, Meta changed the effective date to November 20. Adding to the confusion, Meta then removed the word “train” from a list of allowed use cases,
Nieman Lab reported
, and limited those uses to “advertising and business products,” where previously it said that data would be used for all Meta products. Those terms still allow Meta plenty of leeway for scraping users’ data to develop its products, however.
EU users’ personal data rights are governed by the General Data Protection Regulation and the AI Act.
GDPR
, which became enforceable in 2018, requires explicit consent to use personal data. This includes the right to object to one’s data being used. The AI Act, which went into effect in 2024, dictates how AI companies can use personal data, and how people can opt in or out,
stating
that they can withdraw consent at any time. The UK has its own
version of the GDPR
. The European Commission
states
: “The GDPR rules only apply to personal data about individuals; they do not govern data about companies or any other legal entities. However, information in relation to companies may constitute personal data where it allows the identification of a natural person.”
Several users based in the UK and EU have explained how to object on Instagram. Instagram
user bookish.sil posted
a walkthrough of how they did it on mobile: by clicking the three lines on their account, going to the privacy center, and clicking “object,” which goes to a form that asks users to write why they are objecting to their data being used. They received an email from Meta saying their objection was approved.
Instagram user jenniqueart posted
a similar walkthrough with the same results.
My Meta accounts are based in the US, but using a VPN to locate my IP address in London, I could see options in my Meta privacy settings that would let me object to the use of my information by Meta AI. To get there on desktop with a VPN on, I went to my account
privacy center
, clicked
“Submit a privacy rights request”
at the bottom, selected Instagram, clicked
“How can I object to the processing of my information?”
and got to a page where I could choose to object to the use of my information for Meta AI or third parties, which were two separate options.
When my location is based in the US, these options don't appear.
When I clicked through the option to “object to the use of my information for Meta AI,” however, it returned an error page that said “This form is only available to people in certain regions.” GDPR is meant to apply to wherever someone is located at the time, but since this objection applies to the preferences of one account, it might be based on where the account was created. I tried again located in Belgium and got the same results. I’ve asked Meta to clarify.
As many have already pointed out in the comments on UK and EU users who’ve posted walkthroughs, these objection steps aren’t available to people outside of those countries, and as Meta continuously changes its platform, these steps might not work for everyone always. Unless something changes before November 20, the rest of us are screwed.

The
Redox OS
project, which is a
Unix-like microkernel-based operating system written in Rust, has published a
report
on the work
that it has done in the last year to
implement io_uring-like
I/O
.
Last year, the Redox team received a grant to develop io_uring-like Ring
Buffer support at the system task level, as a first step towards ring buffer
communications between the application and the majority of system services. This
phase of the work finished up in September, as the last pieces were put in
place.
[...] In addition to implementing the Ring Buffer machinery for our system
services and drivers that can support it, an
io_uring
and
liburing
-like API for applications was completed and
demonstrated. There was also substantial work done on support crates, including
an async executor for drivers.
And there was some very exciting work on various performance improvements, to
allow much faster switching between applications and their system services. But
I will let the team tell you all the technical details.
Software teams use agents defined as code to handle recurring work across the development lifecycle. These agents connect to the places where a team works and act when relevant events occur, whether that means reviewing a pull request, executing a compliance workflow, or investigating an incident.
The most useful agents are tailored to how a particular team operates. Until now, building one has generally meant adopting a product designed around someone else's workflow or starting from scratch.
Today, we're releasing the Agent SDK, the framework we use to build our own managed agents like Bugbot, Security Reviewer, and Rollouts. Agent SDK allows you to define agents in code and manage them like any other software project. Start from a template or point your coding agent at our docs. When the agent is ready,
agent-sdk deploy
it to Cursor infrastructure with one command.
Build around your workflow
The Agent SDK lets you quickly build and deploy agents that work the way your team does. They respond to the events your team already handles and follow policies your team can inspect and change.
Code review is one example. Each team has its own standards for what requires attention and who should review it. With the Agent SDK, you can build an agent that responds to pull request events from GitHub, GitLab, or Bitbucket. The agent can assess the risk of a change, route it to the right team, and approve changes that meet your policy.
As an example, a team within Cursor had built a large, fast-growing knowledge base of lessons learned and wanted every pull request checked against it. This way, the team's past decisions would hold even as the codebase changed. With the Agent SDK, they built kb-reviewer in about a day. It now runs on every PR in their main codebase, flags changes that contradict a recorded lesson, cites the note behind each finding, and encourages engineers to reconcile the discrepancies it reports.
For more complicated work, agents can hand a task to another specialized agent with its own tools and sessions. They can also divide a job among subagents working in parallel.
The Agent SDK also supports evals and event replay out of the box, allowing for rapid development with assurances that critical workflows execute the way you expect. The PGA Tour uses the Agent SDK to power their software development factory. Evals keep them moving quickly.
The Agent SDK has enabled PGA to build every component of our software factory on Cursor's infrastructure. It provides the flexibility we need to build agents that drive our development process. And built-in support for evals allows us to quickly iterate on new ideas and optimize existing capabilities reliably.

Define everything in code
An Agent SDK agent is organized like a small software project. The instructions that guide it sit alongside code for its tools, connections to outside services, and the evals used to test it.
Each file represents something the agent knows or can do. Prompts are written in Markdown, while tools are defined as TypeScript functions. Because everything is code, changes can go through the same version control and review process as the rest of your software.
Deploy agents wherever you need them
When you're ready to put an agent into use, you can deploy it to Cursor by running
agent-sdk deploy
from the project directory. The command builds the agent, gives it a URL, and starts it on our infrastructure. You can manage secrets and integrations from the dashboard, while continuing to use the same logs, evals, and playground available locally.
You can also run the agent on your own infrastructure. Each agent runs as a single Node process that can be packaged in a container.
Get started
Getting started with the Agent SDK looks much like starting any other software project. Create a project directory, then launch the local playground:
From there, you can iterate locally and run evals before deploying with
agent-sdk deploy
.
The Agent SDK also ships with skills that guide coding agents through the development process. You can point an agent at the docs and have it help build the bot with you.
The Agent SDK is generally available today. Read the
docs
and get started.
Castle Walls review – Prime’s first fully AI-generated show is here, and it’s a Vaseline-smeared mess
Guardian

Billed as the first end-to-end AI-created series on a major streaming service, this Turkish show looks like the result of the prompt ‘make it cinematic’ Just as the world reels from Elon Musk’s AI-powered The Odyssey remake – though “remake” feels rather generous for a seven-minute splat of syntheti...

ust as the world reels from Elon Musk’s AI-powered
The Odyssey remake
– though “remake” feels rather generous for a seven-minute splat of synthetic sludge – another bucket of AI gunk is dropped on to our faces. For Prime Video’s AI-generated TV series Castle Walls, produced by Turkish production studio Ay Yapım using a melange of generative video tools, has arrived, billed as the first end-to-end AI-created series to premiere on a major streaming platform.
It’s certainly more epic than Musk’s production, consisting of two 17-minute episodes. Set in the 11th century, the show revolves around the historic Alamut Castle, although it’s entirely absent of any real sense of time or place. I was briefly intrigued by the opening images, with their bold palette of blues and mustard browns and yellows – but as soon as the “people” appeared, looking like Vaseline-smeared Madame Tussauds creations slowly melting in the sun, everything came crashing down.
‘Like Vaseline-smeared Madame Tussauds creations slowly melting in the sun’: Castle Walls.
Computer-generated: Amazon Prime Video/YouTube
There are lots of heady moments across the first two episodes of this oddly paced show, with cranky-looking men aplenty and over-milked visual metaphors involving the likes of snakes, blood and fire. Everything looks like it was cooked up with the prompt: “Give me eye-watering visuals.” The opening shot depicts an eagle being transported across a desert in a cage (“make it look cinematic”), followed by a longshot of the castle (“make it more cinematic”), then an aerial shot of men arriving on horseback (“make it MORE MORE MORE cinematic”).
‘Overloaded with grand and imposing imagery’: Castle Walls.
Computer-generated: Amazon Prime Video/YouTube
We learn of the arrival in Alamut of a “freak” who “doesn’t eat or drink” and is intent on claiming these sweet digs for himself. This is Hasan Sabbah, who is supposed to be charismatic but looks plasticky and spectral, with a complexion like wet glue. He has somehow inspired an army of followers and ventures into the castle’s dungeons to recruit one more: the notorious warrior Azazil.
The frame is overloaded with grand and imposing imagery: when Azazil says goodbye to loved ones, of course the scene takes place in front of a milky sunset. When he fangs it across the desert on a horse at night, of course there’s a white full moon glowing resplendently above. When the doors of the mighty castle creak open, in the lead-up to a big moment in episode two, of course incandescent orange sunlight streams through the widening gap.
‘Viewers understandably seem less interested in what the technology promises than in what it threatens to take away: art imbued with humanity.’
Computer-generated: Amazon Prime Video/YouTube
Make no mistake: the technology powering this is amazing and will profoundly alter the state of motion pictures. Productions such as Castle Walls are among the first out of the gates, and therefore prone to snarky commentary. Perhaps AI will end up being broadly comparable to early silent films: revolutionary at the time, but quickly eclipsed by more sophisticated applications of the technology. But whereas the earliest motion pictures, famously dubbed the “cinema of attractions” by the historian Tom Gunning, provided some carnival-like wonder, these AI works tend to evoke a more cynical response from the general public. Viewers understandably seem less interested in what the technology promises than in what it threatens to take away: art imbued with humanity.
The sensible path forward is surely for human and machine to enter into a reciprocal and carefully collaborative process, where artists only use algorithms and prompts to enhance, rather than replace, human creativity. On that front, Castle Walls did use human voice actors and was reportedly written by actual human screenwriters: Kerem Deren and Çisil Hazal Tenim. “This is not a production that bypassed human skill; it is one that used AI to amplify it,”
Ay Yapım has said.
But that’s hardly something to crow about, given how banal and chuckleheaded the writing is, puffed-up with lines like “I’ve stopped being a decent man” and “If I am the sheaf, you are the sword”. Were they really trying to make good art? Maybe that’s a question for ChatGPT.
InfraTrust report warns of exploited flaws in critical network infrastructure
Bleeping Computer
www.bleepingcomputer.com
2026-10-28 10:00:00

Attackers are actively exploiting vulnerabilities across critical network infrastructure, and PHP flaws known as "PHP2Shell" put the web management interfaces of firewalls, VPNs, application delivery controllers, and other appliances at risk.
The findings come from
Eclypsium's October InfraTrust Pulse
, a monthly report tracking security advisories affecting network devices, servers, firmware, chips, and other infrastructure.
Between September 18 and October 14, InfraTrust tracked 133 new security advisories across 18 vendors, covering 2,813 vulnerabilities.
Of those advisories, 37 were rated critical, five had a maximum CVSS score of 10.0, and 58 could be exploited remotely without authentication.
The report also warns that many network appliances, including firewalls, VPN gateways, application delivery controllers, and network-attached storage devices, embed PHP into their management interfaces.
Because vendors compile PHP into appliance firmware, customers commonly cannot install the recent PHP security updates themselves and must instead wait for each vendor to release updated firmware.
InfraTrust therefore recommends that administrators make sure PHP-backed management interfaces are not exposed to the Internet while waiting for PHP2Shell patches.
Critical infrastructure under attack
Some of the most serious vulnerabilities affect systems at the edge of enterprise networks or used to manage other infrastructure.
Threat actors target these devices because they can provide initial access to corporate environments or serve as a springboard for further attacks.
Among the actively exploited flaws highlighted by InfraTrust are:
Citrix NetScaler ADC and Gateway:
CVE-2026-88771 and CVE-2026-88772 were
disclosed on September 27
after attacks had already been observed against unpatched appliances. A
separate NetScaler flaw
, CVE-2026-88779, affecting appliances configured for SAML was also later added to CISA's KEV catalog after exploitation was detected.
Ivanti Connect Secure:
CVE-2026-104935 allows an unauthenticated remote attacker to execute arbitrary commands on vulnerable VPN gateways. Ivanti said it had
exploited a limited number of customers
when it published the advisory. CISA later
added it to the KEV
.
Check Point Security Management Server:
CVE-2026-93616 allows an unauthenticated attacker to upload and execute scripts on management and logging systems. Check Point Research
observed targeted attacks
exploiting the flaw on September 12, targeting Spark customers.
Cisco Catalyst SD-WAN Manager:
CVE-2026-76504 allows an unauthenticated attacker to bypass authentication and gain administrator access to the management API. Cisco became aware of
active exploitation in September
.
Arista VeloCloud Orchestrator:
CVE-2026-93952 is a maximum-severity flaw affecting the system used to configure SD-WAN Edge devices. Arista says
it is being actively exploited
and later disclosed a second,
separate exploited vulnerability
(CVE-2026-114625) in the same product on October 22.
FortiMail
: CVE-2026-104286 is a critical path traversal flaw that allows an unauthenticated attacker to write arbitrary files through the web interface. Fortinet
confirmed it was exploited
in attacks.
Cisco Secure Email Gateway:
CVE-2026-76519 can allow a malicious email attachment to lead to arbitrary file writes and command execution as root on vulnerable systems. Cisco
learned of exploitation in October.
F5 BIG-IP APM:
CVE-2026-94127 is a critical heap overflow that can allow unauthenticated remote code execution on systems configured as OAuth authorization servers. F5 says the vulnerability
has been exploited
.
PAN-OS management interface:
Palo Alto Networks reported
exploitation of CVE-2026-0322 in attacks
on firewalls, allowing an authenticated administrator with network access to execute code as root.
php2shell exposes another problem
InfraTrust also warns that the recently disclosed
PHP2Shell vulnerabilities
expose another weakness in network infrastructure, as many appliances embed PHP directly into their management interfaces.
The two PHP flaws, CVE-2026-109618 and CVE-2026-109619, allow unauthenticated remote code execution, and the PHP project fixed them on October 21.
While most focus on these vulnerabilities has been on websites and web applications written in PHP, PHP is also used for management interfaces of firewalls, application delivery controllers, VPN appliances, and network-attached storage devices.
For impacted devices, administrators usually cannot update PHP themselves because vendors compile it directly into the appliance firmware. Instead, customers must wait for each vendor to rebuild and release updated firmware or software containing the patched PHP version.
Soon after the disclosure, Palo Alto Networks, F5, NetScaler, Check Point, and QNAP confirmed that some of their products were affected, while they still developed fixes for appliances.
The report also highlights a similar issue in other software components that infrastructure vendors bundle into their products.
CVE-2026-31431, a Linux kernel privilege escalation flaw known as
Copy Fail
, has now appeared in 29 advisories across eight vendors, up from 19 advisories from six vendors last month.
InfraTrust also found older, exploited vulnerabilities in bundled components, including an Android kernel flaw affecting HP LaserJet Enterprise printers and a 2020 jQuery vulnerability in Dell Data Lakehouse software.
InfraTrust recommends that administrators prioritize patching NetScaler and Ivanti Connect Secure because these remote-access gateways can serve as a doorway into corporate networks. Next, it recommends Fortinet's October 22 FortiOS, FortiManager, and FortiAnalyzer security updates for internet-facing devices.
The report then recommends focusing on Check Point Security Management Server, Cisco Catalyst SD-WAN Manager, VeloCloud Orchestrator, FortiMail, Cisco Secure Email Gateway, affected BIG-IP APM systems, and PAN-OS management interfaces.
On Tuesday evening, a group of a few dozen demonstrators gathered at
the calisthenics bars in Tompkins Square Park
, and then marched together to a meeting of Manhattan's Community Board 3 on the Lower East Side. They carried signs bearing slogans like "No One Asked For This," and "Repair! Don't Destroy!"
The demonstrators are pissed about the Parks Department's
planned project
to replace the basketball courts, pool, and, most controversially, the exercise bars. The work will make the park more accessible, safer for children, and less prone to flooding. It'll replace the above-ground pool with a larger, in-ground pool. It's expected to take about 18 months, during which parts of the park will be closed—an almost unbearable scenario for many vocal park users.
The community board meeting immediately turned rancorous, with a pro-bars advocate screaming at a board member to "get the fuck out of my fucking face." Board Chair Arnette Scott threatened to call the cops on multiple preservationists, who jeered through a presentation by a representative for the Parks Department. The beleaguered bureaucrat strained to be heard as he confirmed their plans still included replacing the bars with "high quality materials," and bringing the area up to "all applicable codes, including ones that have to do with approach by wheelchairs, and clearances for circulation and safety."
Paul de Rienzo, a retired teacher who later told me he doesn't use the bars, caused such a scene that the Parks Department had to cut their presentation short without explaining what "underlying issues" they had found with the concrete below the basketball courts in their plans to add stormwater detention tanks.
Watching the display, it was hard to decide whether I was becoming an arch liberal, ashamed that the crowd of crowing hippies and tatted software engineer "punks" couldn't act like respectable adults, or a burgeoning Stalinist realizing that bureaucrats should not be accountable to the public. At any rate, I realized I
hated
to see New Yorkers make their voices heard, or at the very least, thought a poor example of civic engagement was being set for the multiple children in attendance.
Other than the pull-up bar obsessives, the public comments consisted of neighbors decrying an affordable housing complex being built on
Fifth Street
, and others urging the board to reject a restaurant permit because the ventilation system would be too noisy.
The October inflection point for vibe game development

I’ve written before about how November 2025 was
an inflection point for coding agents
—the point where Opus 4.5 and GPT-5.1 crossed a tipping point that meant their respective coding agents became reliable daily drivers for software engineers. I think we’ve reached a new inflection point in October 2026, and this time it’s for
vibe coding computer games
.
That last one is particularly important. Models have been able to create something that
looks
like a game for quite a while now, as seen in
my previous experiments
. The challenge has been getting to a game that’s actually
fun to play
.
Game design is a deep subject area. I won’t pretend to be well versed in it—I know enough to have respect for it as a craft. Creating a novel, compelling gameplay loop which challenges players at the right level and provides a satisfying learning curve is a fine art. I didn’t think the models could do it.
Then I tried telling Claude Opus 5.5 to “Make it a LOT more fun”...
and it did
.
In the past few weeks I’ve vibe coded (in the
classic sense of the term
—no looking at the code at all) four games that I’ve genuinely enjoyed playing.
I attended
Foo Camp
in Berkeley over the weekend and met several people who were having similar experiences. Building games that play well is shockingly easy now. The new challenge is coming up with concepts for games that are novel and delightful and that wouldn’t exist without AI assistance.
I haven’t done an exhaustive study, but my current impression is that GPT-6 Astra isn’t
quite
there yet. It can absolutely build a game, but its sense of fun doesn’t match that of Opus 5.5. I expect OpenAI will get there by the end of the year.
Here are the four game projects that have convinced me that the models are now capable of producing fun games with very little guidance. All four are built in HTML and JavaScript and run entirely in the browser.
Tree Appreciator
The smallest game I found to be genuinely delightful is
Tree Appreciator
. I used the regular Claude chat interface for this—it didn’t even need Claude Code.
I built this on a whim while we were driving along
Skyline Boulevard
looking at trees. My prompt was:
Build a three js game called "Tree appreciator" - it shows you two algorithmically generated trees and the game mechanics is about appreciating the differences between them. Think hard about how to make sure it is both fun and beautiful.
I’ve found that telling models to use
three.js
works really well. Claude doesn’t have its own image generation model but is capable of building full-color 3D models that look and feel excellent.
This game required no iteration or follow-up prompting at all—I got the game in a single shot. It gave me back a charming little mobile-friendly spot-the-difference game. You can
play that here
. Here’s
the chat transcript
that built it.
It’s pleasingly relaxing. The graphics are fun, and collecting trees that you have completed in a “herbarium” provides a nice, cosy sense of accomplishment.
Emberwick
This was a more ambitious project that I again built using regular Claude chat. I started out by building an experimental prototype of an engine for a top-down fantasy RPG:
Build a demo game engine three.js which is a top down (but at an angle) RPG - the player gets to move through the world with one or two companions. Create a fantasy village setting that demonstrates walking around outside and then shows how when the player enters a building the wall between the player and the camera goes transparent so the user can see what is happening
Add some NPCs and plenty of furniture and different types of building some with an upstairs - be creative, make it look great
When
that
produced a good result, I decided to push it all the way:
Now turn this into an actual game - quadruple the size of the playable area, introduce fun game mechanics, add a plot that isn't too cliche, some twists, a magic system, make it really good
We’re back to prompts like “make it really good” here! Asking for a plot that “isn’t too cliche” seemed to work too—it’s a bit cliché, but still novel enough that I enjoyed following the story.
Unlike Tree Appreciator, this took quite a bit of additional playtesting and prompting to get to a finished version. This was mainly due to gameplay problems—things like a character not being in the right place to complete a quest because a different story element had caused them to move to another location.
Here’s
that final game
. It has a full story that takes about 15 minutes to play through.
There’s even an experimental level editor if you want to drop in your own houses, furniture, and landscape features.
Once it was all working (and I’d iterated through some gameplay bugs), I played it through from start to finish and found myself emotionally affected by the ending! I’m somewhat embarrassed by this, because
everything
in this game—the graphics, the plot, the characters, the music, the dialog—came from the model. My creative input was pretty much just “it’s a fantasy village and there’s a troll asleep in a cave”.
I also fed that same initial sequence of prompts through ChatGPT GPT-6 Pro. Here’s
the transcript
and
the finished game
for comparison. It looks great, but I don’t think it plays nearly as well.
Battle Drones
This is by far my most successful project, which I
wrote about last week
. It’s a Command & Conquer-style Real-Time Strategy game where two robot armies (or four
as of Saturday
) build units, harvest scrap, and battle over territory.
This is also the project that convinced me that Opus 5.5 knows what “fun” is.
The first versions were built back in July using Claude Fable 5. It got me to a workable 2D Command & Conquer-style game, but it wasn’t great to play.
I prompted Opus 5.5 to “Make it a LOT more fun” and then later to “Port this game to three.js” and the game was transformed. There’s a blow-by-blow account (prompts included) in
my write-up
.
Today, Battle Drones has 2-4 player multiplayer (via a vibe coded WebSockets relay server), medals, replays, seven maps, a random map generator, and a set of “mutators” that add variants of the rules.
It also lets different LLMs play against each other, using a mode where the game advances five seconds and then pauses to give different models time to interpret the new game state and line up their next set of commands. Here’s a replay of
Claude Haiku 5.5 vs. GPT-6 Luna
:
I released Battle Drones under the Apache 2.0 License last Tuesday. On Wednesday Gabriel Turpin released
Panache
(
screenshots here
), a fork of Battle Drones that reimagined the game for steampunk 1900s Belle Époque France, with new models and music and an animated intro sequence. Open source at work!
I decided to try building a game that wasn’t just a cheap imitation of something that already existed, so I set out to create a game about farming pumpkins, growing giant pumpkins, and handling the rush of the October pumpkin season.
I called it “Quarter Sun Cove”.
I’m still iterating on this project, but it’s shaping up quite nicely. It’s a cosy farming simulator where you spend the year tending to your giant pumpkin and planting out regular-sized pumpkins for sale in October, then sell pumpkins during pumpkin season and enter your giant pumpkin in the weigh-off.
Every character in it is a (vegetarian) animal. The mayor of the town is a pelican. You can be a pelican, skunk, raccoon, possum, beaver, coyote, fox, owl, sea otter, or harbor seal. Those species all later show up (accompanied by their children) to buy pumpkins from you.
It’s
absurdly
cute.
You can
play the latest version here
. I’m not convinced by the game mechanics yet—it’s actually quite complicated: you have to decide when to plant pumpkins such that they will become ripe at the weekends in October with the most visitors.
I told Claude to “surprise and delight the user frequently” and the result is
so many
little details and easter eggs. There are mischievous raccoons, an elephant seal that runs the weigh-off, harbor seals that roll their pumpkins back into the ocean, a wandering goat, and superstitions about growing giant pumpkins that
sometimes
come true.
This isn’t my best game yet—it’s not as fun to play as Battle Drones—but it represents the kind of game I want more of: weird, fun, uniquely personal—something that wouldn’t have been built in the before-times.
Four times as insulting
If you are offended by AI-generated art, AI-generated music, AI-generated writing, and AI-generated code, I have bad news for you: vibe coded games combine
all of those at once
.
The wider games community already has an aversion to AI-generated assets in games. This has been a growing issue over the past few years as tools like Midjourney have enabled developers to generate assets for their projects.
This IGN story
covering complaints about slop in Valve’s Steam Next Fest is a good recent example.
We now have games where
everything
—code, assets, dialog, and even the game design itself—can be outsourced to the models. And the results don’t suck!
Building a computer game used to be one of the most challenging projects in all of software development, combining a diverse range of skills and requiring intense focus and effort over many months or even years. And now here I am spitting out a playable multiplayer RTS by prompting on my phone!
I expect that, as we’ve already seen with programming, this will result in a split. Some players will refuse to have anything to do with games that were built in this way. Others may embrace this as opening up game development to a much wider audience. I lean in that direction!
I certainly won’t be entering any of my vibe coded games in traditional game jams or competitions—I don’t feel like I’ve earned that right. We’ll likely see new avenues emerge for vibe game developers to compare their projects.
What happens if someone actually puts the work in?
The thing I find both exciting and shameful about this is that I have got interesting results from
so little creative input
. The projects I’ve described here are loosely ordered by how much effort I’ve put into them. Not a single project represents more than four hours of my work (plus many more hours of Claude Code churning away by itself).
Now imagine what could be achieved by anyone who takes this seriously, invests significant creative time, applies better taste in game design, and then playtests and iterates on the result until it’s as good as they can make it.
I want to see games that wouldn’t have existed without these new tools.
You should build a game!
Building games in this way is
so much fun
. It’s the perfect application for vibe coding because it’s so low stakes: how much damage can you cause with a bug in a personal vibe coded game project?
(OK, you can do some damage... my attempt at audio-based multiplayer gave my wife Natalie
a nasty headache
!)
All of my games so far have been HTML and JavaScript using static hosting (generally GitHub Pages or Cloudflare Pages). Modern browsers—including mobile browsers—are incredibly capable. Frontier models already know libraries like
three.js
and
Phaser
. I’m finding these mobile web games to be indistinguishable from the native experience, at least for the kinds of games I’m trying to build.
Switch to Codex or Claude Code once your project passes the proof-of-concept phase.
And if the game isn’t fun enough, add this:
Make it a LOT more fun
Even after PHP2Shell, blast radius matters more than a CVSS score
Bleeping Computer
www.bleepingcomputer.com
2026-10-28 09:50:59
PHP2Shell shows how quickly attackers can exploit critical vulnerabilities, often before organizations have time to patch. Token Security explains why limiting the access of service accounts, API keys, and AI agents is just as important as fixing vulnerabilities to reduce the damage from a breach. [...
Here's a prediction: we're about to see a stellar quarter for application security companies. PHP2Shell is about to become the strongest budget argument application security vendors have had in years. AI helped researchers find two remote code execution vulnerabilities in
the language behind 69% of the web
, attackers targeted it before the patch shipped, and the pitch writes itself: find more bugs and fix them faster.
Enterprises should rethink this idea. Security teams cannot patch at machine speed, but they can reduce what an attacker can reach after exploitation by focusing on identity as the control plane.
Beyond the initial exploitation, the ultimate incident severity depends heavily on which service accounts, API keys, cloud roles, and tokens the compromised workload can use and what they can access.
From vulnerability to exploitation
First, we need to understand just how much faster exploitation is now. The
two flaws
behind PHP2Shell had been in PHP's code
since 2012
. Researchers at Calif and Wiz found them in August, with help from OpenAI and Google models, and disclosed them jointly with OpenAI.
Exploitation now often starts before disclosure. Unfortunately, things aren't moving as quickly on the remediation side.
Verizon's 2026 DBIR
states the median time-to-fix of a known exploited vulnerability is 43 days.
According to Qualys
, the mean remediation time is 21.2 days, and 63% of critical vulnerabilities are still open after a week. All while around 195 new CVEs are published every day.
PHP2Shell will take longer than most to clean up. PHP ships inside appliances and hosting control panels that customers can't patch themselves. Moreover, versions 8.1 and older got no official builds.
As of October 27,
Censys counted 32.5 million
internet-facing PHP services still running potentially vulnerable versions, and more than 60 million others that don’t report a version at all.
However you look at it, remediation speed will remain slower than the pace of exploitation for the foreseeable future, even when patching itself benefits greatly from AI-driven workflows.
Agents now act across your systems with access nobody has reviewed.
Token Security’s AI Agent Security finds every agent, links it to an owner, and limits what it can do. Identity-based order to control the chaos of your agentic AI
With the exploitation gap widening, it’s tempting to invest everything you can in holding back the tide. But even if an AI-driven scan found 2,000 new zero-day vulnerabilities in your environment tomorrow, that won’t result in a stronger security posture.
It will give you a list. Some items will be easy to patch, while others will need more time than your team has.
For supported PHP branches, the direct fix was simple: install the updated release. Governments and companies still took their sites offline while they waited for it.
Here's another, more optimistic way to look at it. Vulnerabilities lead to exploits, and exploits lead to attacks, but in an enterprise context, the impact of an attack is determined by how far the compromised identities can reach. A shell on a PHP server grants the attacker access to whatever that server can read, from environment variables to cloud keys in config files.
PHP2Shell can also leak worker memory, including passwords, tokens, and API keys. An attacker executing code on one host opens a door to a hallway, but the real valuables are usually in locked rooms.
And the controls that limit lateral movement don't depend on winning a race against discovery. Finding vulnerabilities is an open-ended process, and limiting the reach of a service account is a quantifiable task.
Attackers take the easiest path
This approach has limits. If the vulnerability is in the IdP or the secrets manager, lateral movement capabilities come built in. If it's in the database or in the storage provider, the attacker is already where they want to be.
So with limited resources, it's tempting to stay vulnerability-first: catalog what the advisories and scanners found, triage it, work down from the top. But cataloging takes weeks, and fixing the most pressing findings takes even longer. The bet here is that the most exploitable holes in your core systems are the ones you'll close first.
That bet prioritizes the vulnerability’s severity (the CVSS score) over the blast radius. Attackers aren't looking for the most direct path; they're looking for the easiest path. Taking a leaked credential and moving with it is easier than stringing together zero-days to reach a database directly.
October's other headlines show that path. At LiteLLM,
attackers used a master key
exposed in a public repository to retrieve an unscoped GitHub organization-owner token from an internal agent platform. That identity let them steal two more maintainer tokens, subvert the release workflow, and publish credential-stealing artifacts.
Shrink the blast radius first
You can’t win the race to patch every server before the attackers arrive, but you can determine what a compromised server is worth to them. Discover and inventory every AI agent and non-human identity and
start by securing the ones that reach the most
.
Assign an owner, scope access to purpose and intent, remove dormant credentials, and continuously govern the identity lifecycle. For AI agents, go further and grant access by intent. That is what it means to treat identity as the control plane.
Patching decides how fast you close a hole. Identity decides how much an attacker gets when you can’t.
Two new Raspberry Pi boards have quietly turned up in Raspberry Pi’s Linux kernel tree, and neither of them is quite what I’d have guessed. Device tree files for a Raspberry Pi Zero 3 W and a Raspberry Pi 4 Model A have landed (
Phoronix also spotted it
), and whilst there’s no official announcement just yet, device tree files tend to give away a surprising amount if you can decipher them and I gave it my best shot.
Raspberry Pi Zero 3 W: A Pi 4 Shrunk Down?
The Raspberry Pi Zero 2 W launched almost exactly five years ago (tomorrow, in fact), so a successor has been a loooooong time coming. If you want a refresher on where things stood back then, my
Raspberry Pi Zero 2 W vs Zero W benchmarks
piece covers the jump from the original pretty well.
The headline from the
Zero 3 W device tree
is the SoC. It’s the
Broadcom BCM2711
, the same quad-core Cortex-A72 chip that powers the
Raspberry Pi 4
, replacing the
Zero 2 W’s
quad-core 1GHz Cortex-A53 RP3A0. If you want an idea of the sort of gap we’re talking about, it’s worth having a look at
how those two compare on sbc.compare
. That’s a big step up in per-core performance, and if they can get anything close to Pi 4 clocks in that tiny footprint, it’ll be a hell of a lot of compute for a Zero. I do wonder how toasty it’s going to get though, as the BCM2711 isn’t exactly known for running cool, and there’s not a lot of board for the heat to spread into. The device tree doesn’t tell us anything about clock speeds, so we’ll have to wait and see whether it’s been dialled back.
Beyond the SoC, here’s what else stood out to me:
eMMC on a Zero?
The storage controller is configured with an 8-bit bus width and a comment describing it as driving “the eMMC/SD card”, which only really makes sense for eMMC. I’d love to see it, but I’m not expecting it to make the final board, as it’d push the price up on a range that lives and dies by its price tag. My money is on this being a leftover or an option kept open during development, and microSD being what we get.
An SPI flash bootloader.
The GPIO names include SPI flash lines, which suggests the Zero 3 W gets the same EEPROM-based bootloader as the Pi 4 (the Zero 2 W never had one). That should bring the Pi 4’s boot options along with it, and the ability to
update the bootloader
in the usual way.
A single HDMI output
, with the second HDMI controller permanently disabled. No surprise there given the form factor.
A power button
defined on GPIO 46 and mapped to KEY_POWER, so we may be getting a physical button (or at least a header for one) much like the Pi 5.
Wi-Fi and Bluetooth
wired up in the same way as the rest of the BCM2711 family, with a single ACT LED for status.
The usual 40-pin GPIO layout
(GPIO 0-27 with the ID EEPROM pins), so your existing HATs should be fine.
There are a couple of more speculative bits too. The PCIe controller is enabled and there are lines named PCIE_PWR_EN and PCIE_DET_WAKE, and the camera side pulls in a 4-lane CSI configuration rather than the 2-lane one the Pi 4 Model B uses. It’s worth noting that both device trees share a lot of copy-and-paste DNA (the Zero 3 W even has a duplicated “PWR_GPIO” line name), so I wouldn’t read too much into either of those until we see an actual board. I’d love to see PCIe exposed on a Zero, but I’m not holding my breath.
Raspberry Pi 4 Model A: The Return of the A
The second surprise is a
Raspberry Pi 4 Model A
. We haven’t had a Model A since the Raspberry Pi 3 Model A+ back in 2018, and the formula has always been the same: take the Model B, strip out the bits most people can live without (RJ45, some USB ports etc), and knock a chunk off the price. The Pi 4 Model A looks to follow that recipe pretty closely, though the price comment may not quite hold. Let’s see!
No Ethernet.
The Ethernet controller isn’t enabled anywhere, and the GPIO lines that drive the Ethernet PHY on the Model B have been repurposed. Very much in keeping with previous Model A boards.
A single HDMI output
rather than the Model B’s dual micro HDMI.
No 3.5mm audio/composite jack.
The analogue audio pins are empty and the composite video encoder is disabled, so audio will be over HDMI (or USB/I2S if you’re that way inclined).
microSD only
, with the same 1.8V signalling support as the Model B for the faster UHS card modes.
External antenna support.
This is the one I find most interesting. There are two antenna control lines (ANT_CTRL1 and ANT_CTRL2) and overlay parameters named
ant1
,
ant2
and
noant
, which is exactly how the Compute Module 4 switches between its onboard antenna and an external U.FL connector. If that carries over to the final board, it’d be a lovely addition for anyone sticking a Pi in a metal enclosure.
PWR and ACT LEDs
, the same SPI flash bootloader setup as the Model B, and the same power button definition as the Zero 3 W.
The device tree doesn’t tell us anything about USB. On the Model B, the USB 3 ports made use of the PCIe bus, and the PCIe controller is enabled here too, so USB 3 is possible, but the 3 Model A+ only had a single USB-A port and I’d probably expect the same here.
The previous Model A, the Raspberry Pi 3 Model A from 2017
How Do They Compare?
Here’s a quick side-by-side of what the device trees tell us, with the Pi 4 Model B thrown in for good measure. Anything marked with an asterisk is my interpretation of the device tree rather than something it states outright.

What We Don’t Know (Yet)
Quite a lot, I’m afraid. Device trees don’t describe RAM, so there’s no word on memory configurations, and there’s nothing on pricing, clock speeds, connector types or a release date either.
Pricing is the big one for me. Memory costs haven’t exactly been kind lately (I covered the last round of increases alongside the
1GB Raspberry Pi 5 launch
), and a lower-cost Pi 4 variant makes a lot of sense in that context. The BCM2711 is a mature chip at this point, it’s well supported in software, and a cut-down board gives people who don’t need a Pi 5 something cheaper to reach for. The Zero 3 W is a tougher one to call though, as the Zero range has always lived and died by its price, and I can’t imagine the BCM2711 being as cheap to build around as the RP3A0.
Thoughts
On the whole, I like what I’m seeing here. The Zero 3 W looks like the upgrade a lot of people have been asking for since the Zero 2 W landed, and the 4 Model A feels like a sensible way of squeezing more life out of the Pi 4 platform at a time when components aren’t getting any cheaper. The external antenna support on the 4 Model A is a really nice touch if it makes it to the final board.
Saying that, everything above comes from device tree files rather than an official spec sheet, so mileage may vary when the real thing turns up. Kernel support landing ahead of launch is usually a good sign that it’s not far off, and you can bet I’ll be throwing both the Zero 3 W and the 4 Model A onto
sbc.compare
as soon as I can get one in my hands.
Which of the two are you more excited about? Do let me know in the comments!

Forging a Microsoft Edge Full Chain with Logic Bugs Only
I think I should still dump some of my work once in a while, even though it feels like fewer and fewer people actually sit down and read articles these days (or maybe now they all leave it to their agents XD). Anyway, this is what I built for Pwn2Own Berlin 2026 — a completely handmade, logic-only Microsoft Edge Full Chain, with no memory corruption, and no AI at all! 🔥
Confirmed! Orange Tsai (@orange_8361) of DEVCORE Research Team (@d3vc0r3) chained 4 logic bugs to achieve a sandbox escape on Microsoft Edge, earning $175,000 and 17.5 Master of Pwn points. Full win! #Pwn2Own #P2OBerlin https://t.co/vJaIpGG4cD
The whole chain is made up of five bugs and two Windows features. I have also shared the whole bug-hunting and chaining process at this year’s HITCON and Hexacon, plus some fun stories along the way. You can check
the slides here
!
Also, maybe everyone thinks LLMs can already pwn everything in the AI era, so something made entirely by hand somehow feels a bit more precious. That might also be why this chain was nominated for this year’s Pwnie Awards and won the Epic Achievement award. 🎉
Let’s Navigate!
So where do we start with a logic-only full chain? Well, since it’s a “browser,” let’s start by looking at how “browsing” (or what Chromium calls “navigation”) works. I won’t go into too much detail in this post, because I think in this era, you can just ask your agents to fill in the details :)
But I’d still recommend reading “
Life of a Navigation
“ from Chrome University if you want to get the full picture.
The Forgotten Navigation Throttles
While I was walking through the Chromium Navigation flow, something called “Navigation Throttles” caught my attention. They live in the Browser Process, and intercept all navigation requests initiated by either the Browser or the Renderer. Maybe it’s easy to say this in hindsight, but out of the 3,000+ CVEs Google Chrome has fixed over the past five years, there are only fewer than 20 related to them. So I guess this is also a corner not too many people pay attention to.
Anyway, I started digging into the Navigation Throttles, and checked how Google Chrome and Microsoft Edge implemented them. And while going through the code, I found that Edge has a throttle called
EdgeCAGuidanceNavigationThrottle
for its enterprise Entra ID feature (the
CA
here stands for
Conditional Access
). The purpose of this throttle is to guide users to the right User Profile when Edge detects them signing in with a work account on a Microsoft website. And to fire this throttle, you have to start a navigation from a specific Microsoft-owned origin, such as
login.live.com
:
And once the throttle is fired, Edge would compare the email of the current User Profile with
?email={email}
. If they don’t match, Edge pops up a dialog guiding you to switch accounts.
But if they do match, Edge would then grab the URL you were originally heading to from
switch_profile={url}
, and launch a new navigation with Chromium’s internal Navigation API:
So basically, the throttle cancels the original navigation when the target URL matches a specific internal format, and then launches a new one with the URL from the attacker-controlled Query String, if the conditions are met. Since this new navigation is initiated by the Browser Process, in theory we can do a few things we couldn’t do before, such as jumping to normally prohibited pages like
edge://settings
or
devtools://...
, or even pseudo-schemes like
javascript:alert(origin)
.
Though the JavaScript pseudo-scheme sounds like a powerful primitive, you still need to obtain the Execution Context on
login.live.com
to fire the throttle in the first place. So being able to jump to
javascript:
doesn’t really give you any extra capability. At most, it’s just like a Self-XSS, or a way to turn an Open Redirect there into XSS. Either way, you’re still only executing JavaScript in the same
login.live.com
context.
Honestly, I didn’t take this bug too seriously at first glance. To me, it was just a stronger Open Redirect that could jump to a few more Browser-Level Schemes, and still needed to be chained with other bugs. So the bug just sat in my notes for weeks… 🤦♂️
Sourceless Navigation: A New UXSS Primitive
The turning point was when I was going over the Chromium architecture one day and started thinking: The throttle is handled in the Browser Process, so the new navigation is initiated from the browser as well. However, the page we fired the throttle from,
login.live.com
, lives in the Renderer, and while investigating the logic, I couldn’t find any code tying the Browser and Renderer together. So…
CURRENT_TAB
refers to which tab, exactly?
To find this out, I ran a quick test and added a delay to the original trigger:
And during the delay, we manually switched the Edge to a new tab to see what would happen, and…
Boom! We got a UXSS on
google.com
, and that’s also the first bug of the whole chain. To fully understand the UXSS root cause, we dug into Chromium’s source code. We found that if
Navigate()
is called without specifying the
source_contents
(the Renderer source to bind to), Chromium would use the current active tab as the Renderer source automatically.
Though the code path requires
params.disposition
to be
CURRENT_TAB
and
params.source_contents
to be
NULL
, luckily, those are the defaults, so even Chromium’s own
example code
gets this wrong. I guess this should count as a new UXSS attack surface!
The 0-Click Challenges
The UXSS primitive we just got sounds great, but firing that still comes with quite a few challenges in practice. Here we list four we faced while weaponizing the UXSS, and how we cracked them with more and more bugs 😉.
1. The Throttle Must Be Fired from a Trusted Origin
The first challenge, as we mentioned earlier: this UXSS has to be fired from certain Microsoft sites. Though we could still find an XSS there to make that happen, that sounds like a painful job, so we’d keep it as a last resort. Instead, we decided to see if there was any low-hanging fruit in the origin check first.
if ( !IsSupportedLoginUrl(last_committed_url) ) return content::NavigationThrottle::CANCEL_AND_IGNORE;
We found that
EdgeCAGuidanceNavigationThrottle
uses
GetLastCommittedURL()
to retrieve the origin that fired the navigation, and then check it. At first glance, this looks like the correct way to do the validation. But take a second look, and you’ll notice Microsoft seems to have forgotten that a navigation can come not just from the current
WebContents
, but also from another window… So a simple
window.open(...)
is enough to bypass it!
↓ You can run this on any website to fire the throttle
So far, we can bypass the origin check with a cross-window navigation. However, modern browsers don’t let webpages open new windows that easily nowadays, so here comes another new problem: the
Popup Blocker
would block
window.open(...)
by default.
To crack this, we kept reversing Microsoft Edge. And we found Microsoft, maybe for internal use, made its own hardcoded whitelist for popups… So a popup like the following would normally be blocked as expected:
But if you swap the URL for the whitelisted one… the window just appears. And then remember to navigate it back to the original site, and you’ve bypassed the Popup Blocker!
Now that we can fire
EdgeCAGuidanceNavigationThrottle
from wherever we want, the next step is to get past the Conditional Access checks. The code first requires Microsoft Edge to already have a signed-in User Profile, and then checks if
?email={email}
matches the profile’s email. Both conditions have to be met before we reach the sourceless, browser-initiated navigation to finally trigger our UXSS primitive.
However, since we can’t assume the target environment has a signed-in profile in advance, we still need to find a way to make the attack work even if it doesn’t. While exploring Microsoft Edge, we came across a great feature called “OneAuth”. The feature lets any Edge WebView application automatically sign in with your current MSA credentials when visiting Microsoft-owned sites. And it turns out that starting with 25H2,
Windows OOBE
requires you to sign in with an MSA (unless you use the local-account workaround). So even if you’ve never created a User Profile in the browser, just visiting
www.microsoft.com
is enough for Edge to create one and sign you in automatically.
Thanks again, Microsoft!
4. The Need for Prior Knowledge of the Login Email
With the sign-in issue cracked, the last challenge is to get the victim’s email in advance. Of course, we could try some social engineering, or keep reversing Microsoft Edge to find another bug that leaks that for us. But since the automatic sign-in already sets several Microsoft cookies, we thought Web Hacking would be an easier way to steal the email. So we fired up Burp Suite and started looking for web vulnerabilities.
We spent a few hours and found several XSS bugs on Microsoft sites. While poking around, I noticed that
assets.msn.com
, which is embedded in
edge://new-tab-page-online
, returns the currently signed-in user’s email. And even more interesting, when I checked the response header, the site seemed to have a CORS misconfiguration…
So with a simple
fetch(...)
with credentials included, you can easily grab any Microsoft Edge user’s email from any website:
So far, to make this primitive work, we’ve chained together:
A Trusted Origin bypass caused by a missing cross-window Opener check
A Popup Blocker bypass caused by a hardcoded whitelist
A OneAuth feature that automatically signs you in
A CORS misconfiguration that lets us steal the signed-in user’s email
Now we can finally trigger the UXSS without a single click! And even better, since this UXSS is initiated from the Browser Process (
HandleRendererDebugURL
in Mojo, if you’re interested), it can ignore any CSP entirely. That means we can run JavaScript on
google.com
,
facebook.com
,
icloud.com
, or whatever website we want!
Breaking Out of the Browser Sandbox
So we have a Universal XSS. Does it mean that we can do whatever we want? If we’re talking about Web Security, then yes. But our goal here is to get ACE (Arbitrary Code Execution), so UXSS alone is far from enough. And we still need to find a way to break out of the Browser Sandbox to turn this UXSS into code execution.
The first and most straightforward idea that came to my mind was: since we can run JavaScript on any website, or more precisely, any origin, why not just leverage privileged WebUI pages like
edge://settings
or
edge://downloads
to get ACE?
This naive approach was of course already mitigated by the Chromium developers. In the Renderer’s Mojo handler, there’s an extra check: if the origin belongs to one of the following privileged WebUIs, the Renderer simply ignores the JavaScript URL.
Basically, Chromium has put every privileged WebUI you can think of on the
not_allowing_javascript_urls_schemes
blacklist. So at that point, I still got stuck for a long while. 😖
Arbitrary File Write via Immersive Reader
However, as we continued exploring Microsoft Edge, we found that Edge had its own Reading Mode called
Immersive Reader
. And unlike Chrome’s built-in Reading Mode, Immersive Reader seems to have been forked from Chromium early on, with Microsoft building on top of it. So instead of the old
chrome-distiller://
or the blacklisted
chrome-untrusted://
, Edge uses a custom
read://
scheme. And Microsoft seems to have forgotten to add this scheme to the blacklist as well, so our UXSS works on this privileged WebUI :)
Starting from this privileged WebUI, we can access lots of native C++ objects through JavaScript. And one of them called
chrome.edgeFeedbackPrivate.zipDiagnosticLogFiles()
looked particularly interesting to me. We tried it out, and found that the function takes two parameters, a filename and a JSON string:
↓ We ran this on
read://https_orange.tw/?url=https://orange.tw
While playing with it, we observed that Microsoft Edge would first create a temporary folder and write
AAAAAAAA
to the file
ORANGE.json
. It would then pack the whole folder into
LOL.ZIP
, upload it to a Microsoft server, and clean everything up afterward. Of course, you’d want to try
../
… Yes, it does let you escape the temporary folder. But that
.json
extension is still a bit annoying. Maybe you’re also wondering if a NULL Byte could get rid of it… Of course it can! So now we have an arbitrary file write that can control both the filename and the content, and we can overwrite any file anywhere we want!
Thank you again and again, Microsoft!
Overwriting
protocols.json
to Auto-Launch Protocol Handlers
Now, we’ve got almost all the pieces. The last step is figuring out how to turn a browser-level arbitrary file write into ACE to complete the chain. We observed that Microsoft Edge would do some interesting side-loading while initializing, such as reading a bunch of config files or loading DLLs from a writable folder.
So the DLL side-loading sounds juicy. However, since our file write is wrapped in JSON, the content has to be a valid UTF-8 string. And because Microsoft Edge is a 64-bit process, we’d have to drop a 64-bit DLL, too. After spending some time working on this, we found that we couldn’t construct a valid 64-bit PE header that met the UTF-8 requirement in any case, so we gave up on DLL side-loading.
We ended up solving this in a less obvious way. We found that besides OneAuth, Edge also loads a bunch of components while initializing, and one of them is “AutoLaunchProtocolsComponent”. The component would read a configuration file called
protocols.json
from a folder we can write to, and that file defines which origins are allowed to launch which URL protocol handlers. So by overwriting the file, we can launch any protocol handler from any origin.
As for how do we get Microsoft Edge to re-initialize? Just use our earlier browser-initiated navigation to jump to
edge://restart
! :)
From
telnet://
to Code Execution!
Here we chose
telnet://
to get code execution. On Windows, the telnet handler would try to invoke
telnet.exe
, but the binary isn’t shipped by default, so Windows goes looking for it in the directories listed in the PATH environment variable. And one of those directories just happens to be writable by us…
So by simply dropping a modified
protocols.json
and a 32-bit tiny PE, we got ACE. The whole exploit is less than 100 lines of code. The restart isn’t really necessary in a real attack, only for Pwn2Own. Let’s check out the demo! 🔥
Final Thoughts
From zero experience with modern browser exploitation to completing the full chain, the whole research took me two full months, with no LLMs/AI involved at all. But why, you might ask? Perhaps because it sounds cool, or maybe it was also just good timing — I only started using coding agents like Codex and Claude Code around March this year, and by then, I’d already found all the bugs and done the hard part ¯\_(ツ)_/¯
So what’s the hard part? For memory corruption, it’s often the exploitation. But we’re playing with logic bugs, where the hard part is finding them, and once you find them all, chaining is the easiest part. So that’s also why I kept the whole exploit AI-free.
Apart from that, I also see the UXSS primitive as a new attack surface, and agree that in the AI era, “
Attack Surface is the new 0day
“. I wanted to explore this gold mine more before sharing it with the AI giants. That’s another reason why I decided not to use AI on this chain.
Of course, I’m not some old-fashioned guy who refuses to try new things, either. Outside of this chain, I’m also tokenmaxxing and addicted to AI. I believe once you’ve tasted how convenient LLMs are, no one would want to go back to hunting bugs by hand. That’s also the future, I think.
I’m also not that afraid of being replaced by AI. I’d rather say it’s precisely because of AI, I finally have enough time to finish all the cool stuff that’s been sitting on my TODO list… like the
Windows RCE I just reported
, flipping the chain to
pop Microsoft Edge from
calc.exe
, or porting this logic-only full chain to Google Chrome (almost there ><). I’ll also show some progress at
CODE BLUE in Japan
next month. Stay tuned! 😉
So instead of worrying about how low the bar for vuln research can go, why not get excited about how high AI can take us? What fun can we have, what even cooler hacks can we build, and what impossible things can we make happen…?
Never Stop Exploiting!
Show HN: Nasscad – local-first 3D CAD for browser and Windows
Valve has advised developers concerned about AI clone games to focus on community building and consistent updates. The trust built with players serves as the strongest barrier against clone games, and the features and distinct identity continually added through updates cannot be easily copied like a single mechanic. Valve's Steam Business Team shared these insights at the 'Steam Indie Connect' developer event held on October 27, stating that making the genuine version the best version has long been Valve's core principle.
The event was co-hosted by Valve, the Busan Indie Connect Festival Organizing Committee, and the Korea Creative Content Agency (KOCCA). Taking the stage were Tom Giardino and Marc Wilkinson from Valve's Steam Business Team, joined for the Q&A session by Matt from the localization team, which oversees translations into 30 languages for Steam and Valve games. Amid a flood of AI-generated games, Valve representatives directly explained to Korean developers how Steam handles visibility and curation.
"Launch Is Not the Finish Line, It's the Starting Line"
Tom Giardino opened the presentation with an update on Steam's current status. According to the presentation materials, Steam, which launched on September 12, 2003, recently reached a peak of 43.5 million concurrent users worldwide. Total Steam revenue in South Korea grew 126% over the past five years, with premium game and DLC revenue increasing by 70% and in-game purchase revenue surging by 388% over the same period.
He then outlined the launch preparation process — spanning Coming Soon pages, demos, Next Fest, playtests, setting an official release date, and build reviews — remarking, "Launch feels like the finish line, but it's actually the starting line." He also urged developers not to rely solely on Steam, but to utilize consoles, other PC stores, Discord, and social media alongside it.
Marc Wilkinson introduced new tools. Key among them are the Wishlist Data API, which allows developers to retrieve wishlist data by period, country, and language by specifying an App ID and date range, and the 'Personal Calendar,' which transitioned from a Steam Labs experiment into an official store feature. The Personal Calendar recommends upcoming releases wishlisted by players with similar play styles, and games must have a set official release date to appear on it.
Threatening Emails Saying "We'll Copy Your Game with AI and Launch First" — Valve's Answer
The question regarding AI cloning stemmed from a specific threat. One developer shared that indie developers have recently been receiving extortion emails threatening, "If you don't pay, we'll clone your game with AI and release it first." While understanding the advice to showcase games prior to release, the developer noted that such threats could make creators hesitate and asked if Steam had protective measures in place.
Tom Giardino expressed regret, noting that this was the first time he had heard of such extortion cases. He started with Valve's underlying principle regarding new technologies. "We don't want to be gatekeepers telling developers which tools they should or shouldn't use," he said, stating that whether to use AI in development is a decision for the developers themselves.
However, he pointed out that clone games existed long before AI. Spotting an interesting concept during Next Fest and quickly making a similar game or chasing trends has always happened; AI has simply accelerated that pace.
He framed this as creating two challenges for developers. The first is community. Building a developer website, engaging with players, and establishing identity and trust serves as the first line of defense against clone games, whether AI was involved or not. However, he added that because it takes time and does not happen automatically, community alone is not enough.
The second is continuous improvement. He emphasized that this task is equally important for small indie studios worried about AI clones and for Valve, which operates Dota.
As evidence, he pointed to Valve's philosophy on anti-piracy. Valve has historically not been aggressive with DRM or anti-piracy measures. Instead, it placed weight on making the legitimate version the best version available, and he explained that Valve views AI cloning through the same lens. Giardino said, "Rather than relying on a single mechanic that someone can easily copy, you need to keep growing your game by adding features, personality, and creativity that stem from your own perspective."
While drawing a line on the extortion itself, he kept communication channels open. He noted that such extortion is closer to an issue for law enforcement agencies rather than a game platform to solve. Even so, he added, "If you report such cases to us, we want to look into them further and help in whatever way we can."
'AI Slop' Hits Next Fest — "First Two Days Use Random Exposure"
The issue of AI slop (low-quality games made with AI) was also brought up. A developer who recently participated in Next Fest noted that complaints had surfaced on community channels and social media about an influx of low-quality games, and mentioned having experienced disappointing results personally. They asked whether Valve was aware of the issue and if solutions were planned for the next Next Fest.
Marc Wilkinson explained the visibility structure of Next Fest. For the first two days of the event, games are shown to players on a virtually random basis. After that, personalized recommendations kick in, surfacing more games that a player is likely to enjoy and purchase. He pointed out that many articles complaining about a flood of low-quality games were written based solely on those first two days.
He also shared the reason behind starting randomly. It is to prevent system abuse by those trying to enter early just to gain immediate visibility, and to give every game a fair share of exposure during Next Fest. "We recognize that the trade-off is some low-quality games get exposed," he said. "We are fully aware of the situation, and a significant number of people are thinking about how to solve this problem."
Tom Giardino highlighted the shift in scale. Just three years ago, he was going around trying to convince developers to participate, saying, "There are only 50 or 100 games, so you should definitely join," but now the number of participating titles reaches into the thousands. He described it as "the pendulum swinging to the opposite side."
He also pointed out that the benchmark for success varies for each game. There are titles overjoyed to gain 10,000 wishlists during Next Fest — tripling their previous total — while others are disappointed even after gaining 50,000 because it fell short of expectations. "As platform operators, we can't define what success means for an individual game," he said, explaining that Valve chose to keep the doors open for both Next Fest and seasonal sales while continuously refining page layouts and placements.
He noted that this concern was not new. When Steam Greenlight launched around 14 years ago, developers asked if Greenlight games could be filtered out. When Steam Direct, the current self-publishing system, was introduced, requests came in for a checkbox to hide Steam Direct games. Every time, rather than turning developers away or trying to pre-filter good games from bad ones, Valve chose to improve the shopping experience.
Giardino said, "We don't think we're perfect and there's plenty of room for improvement," but added, "Rather than limiting developer access, making Steam a smarter and more dynamic platform is the starting point of our philosophy."
"Wishlists Have No Impact on Visibility — They're a Thermometer for Marketing"
Questions around visibility transitioned to wishlists and the Personal Calendar. One developer observed that because Steam's main front page has focused primarily on top sellers among new releases, studios have obsessively chased 'wishlist farming,' increasing the importance of publishers who assist with it. Expecting that personalized recommendations via the Personal Calendar will become crucial for indie game exposure, the developer asked about Valve's intentions for expanding the feature and how developers should prepare.
Marc Wilkinson first corrected a misconception regarding wishlists. He clarified that while wishlists are a good indicator of marketing performance, they do not affect visibility on Steam. "What drives visibility is the number of people buying and playing the game," he emphasized. He shared examples of games that launched with 3 million wishlists but suffered falling sales and dropped off top charts due to poor user experience, as well as games with virtually no wishlists that achieved massive success. He advised against wishlist farming, urging developers to focus instead on making a great game.
Tom Giardino redefined the role of wishlists, pointing out that many developers do not utilize wishlists enough to measure marketing effectiveness. For example, checking if wishlists increase after running an ad, posting TikTok videos for a week to gauge reaction, and then testing different methods on other platforms. He noted that tactics that worked for a first game might not work for a second game years later. "Don't treat wishlists as a magic number you have to hit; use them as a thermometer or speedometer to measure the effectiveness of your efforts," he said.
He also detailed the design intent behind the Personal Calendar. While only a subset of users tested the Personal Calendar during its Steam Labs phase, becoming an official feature means far more player response data will be gathered. He explained that this feature differs from other Steam features because it revolves around recency. While top store recommendations and top seller lists include games from years ago like 'GTA 5' or 'Tactical Breach Wizards,' the Personal Calendar is virtually the only space dedicated exclusively to brand-new releases.
He did not hide its limitations either. Once 1-2 weeks pass after release, exposure on the Personal Calendar does not happen again. After that, the hard work of discounts, DLC, and game improvements remains. Nevertheless, he noted that the Personal Calendar was designed to reach deep into the catalog. "It doesn't matter if this game is a global top seller. What matters is whether there are enough signals indicating it will be popular with you personally," he said, stating that Valve will continue to refine the feature so games can connect with their audience even if they aren't top sellers.
Dilemma Over Tags and Single-Player Options — "A Design Choice, Not a Business One"
Questions about tags were also raised. A developer creating a game centered on co-op for two or more players asked whether single-player tags or solo options heavily influence wishlist conversion rates and refund rates, and how to communicate it on the store page if the game remains co-op only.
Marc Wilkinson responded that specific genres or features do not guarantee success. Steam has players who enjoy VR, single-player, and multiplayer games alike, and co-op-only games like 'It Takes Two' have achieved massive success. Ultimately, he said, it comes down to game quality.
Tom Giardino pointed out that major titles like 'Marathon' and 'ARC Raiders' grapple with the same dilemma between players who want to play solo and those who play with friends. He explained that Valve has never analyzed wishlist conversion rates by genre or game type, so he couldn't confidently say that adding a single-player tag increases conversion. Instead, he cited Valve's 'Left 4 Dead' as an example. While best enjoyed with three friends, not everyone has friends available, so delivering an experience close to multiplayer even when playing solo was a key design objective.
He advised that if a studio has the budget and resources to build bot companions that approximate multiplayer, they should pursue that path; if not, they should confidently step away from it. "In the end, it's a design choice, not a business choice," he said, noting that having a single-player checkbox is not a prerequisite for success.
He also shared tips on selecting tags. Giardino suggested referencing competing titles, as their tags, supported languages, and features are largely public. If building a game similar to 'XCOM' or 'STAR WARS Zero Company,' he suggested looking not only at those two titles, but also at games positioned directly beneath them that compete more closely. If top tags are Action, Indie, or Strategy, there are around 100,000 games sharing those exact tags, so finding specific tags that highlight the game's unique identity is a better approach.
He also recommended partnering with developers of competing games — asking whether Brazilian Portuguese support was effective, which localization agency was used, cross-promoting through 'collaborative bundles,' or recommending similar games to each other's fanbases. He noted that the global indie developer community is surprisingly open.
86% of Sales in Korea — "Find Local Champions"
Concerns about expanding overseas were also discussed. A developer who launched a co-op multiplayer game in Early Access shared that while sales grew, 86% of total sales came from South Korea. Despite engaging influencers in Japan, Germany, and the U.S., driving overseas sales using Steam's native features post-launch proved difficult, prompting the developer to ask how to market an already launched game abroad. When Tom Giardino asked about language support, the developer replied that the store page was translated into every language supported by Steam, and the in-game text had completed LQA for 16 to 17 languages beyond Korean.
Tom Giardino noted that while language is a significant barrier, certain games perform exceptionally well in specific countries due to the nature of their content — such as farming simulators selling heavily in Germany or Poland even without supporting German or Polish. However, he noted such cases are rare, and enjoyable games generally earn love evenly across regions. Marc Wilkinson highlighted regional pricing. While developers set prices, Steam operates a recommended pricing system for smaller teams lacking resources to analyze pricing individually, adding that regional pricing appropriate for local markets is a key factor for success.
Giardino reassured the developer, saying, "Breaking out of your home country's fanbase is inherently difficult. Your team isn't doing anything wrong." He noted that Brazilian studios often find that the majority of their customers are Brazilian as well. He pointed out that games that succeed abroad usually have a 'cheer squad' or champions in the new region — not PR agencies or paid ads, but local individuals like streamers, journalists, and YouTube reviewers. His advice was to find local figures in major markets like Germany, the U.S., Canada, Australia, France, and China who will champion the game.
He also called for the localization of update announcements. He pointed out that games initially supporting multiple languages often post Steam events or new feature announcements only in English, frequently losing engagement from Korean and Japanese players.
Matt affirmed that translating the store page first was the right call. He likened localization to a 'chicken-and-egg' problem: it is difficult to know whether a game lacks customers because it isn't translated or if translating will create customers, carrying financial risk. He recommended gathering as much data as possible using tools like the Wishlist Data API before deciding. He also noted recent shifts allowing 30 languages to be added at once using AI translation. Furthermore, he added that conditions vary by region — such as in Japan, Thailand, and Indonesia — so developers should research whether a genre resonates in a given market before deciding on launch plans and resource commitment.
Publishers and Steamworks Permissions — "Many Features Already Exist"
Friction when using Steamworks alongside publishers was also brought up. A developer noted that indie studios lacking marketing and localization experience frequently sign with publishers, but because Steamworks is tied to accounts, unnecessary or personal information is often exposed to publishers. They suggested a feature allowing developers to grant permissions to publishers strictly within the scope of their contract.
Tom Giardino explained that features to share sales data viewing permissions and App ID access permissions already exist. However, because the depth of relationships and permission holders vary by contract, it remains complex for Valve to handle. He cited developer education as one of the biggest challenges, noting that at events like this, requests are made to let publishers share sales data, even though that feature has been available for a long time. He welcomed feedback, stating that Valve wants to make improvements if specific permission issues are brought to their attention.
A CEO of a VR game studio asked whether curation, visibility, and policies for VR games would change given Valve's launch of its new hardware, 'Steam Frame'. They also mentioned anxiety among VR fans that Valve might be abandoning VR.
Giardino responded, "We still believe in virtual reality." He revealed that many Steam Frame users play standard library games rather than VR titles, using the Frame as a display. He framed VR's challenge as another 'chicken-and-egg' dilemma: developers wait for a larger VR market, while players wait for more VR games. Meanwhile, non-VR games keep growing more diverse and compelling, taking up players' time and money. He diagnosed the reality of new titles like 'Escape from Tarkov' launching every week as the biggest hurdle facing VR developers.
He stated that Valve views Steam Frame as just one piece of the VR ecosystem. He explained that Valve put significant effort into the Steam Link app for Meta Quest and OpenXR support so users who purchased headsets from other companies could still access the SteamVR experience. He also spoke candidly about component costs, noting that rising prices for parts like RAM and memory increased costs for all hardware, including Valve's, despite their desire to price Steam Frame lower to attract new users. "Moments where we could have welcomed many new customers became reasons to hesitate or wait on VR," he said, adding, "We feel sorry to VR developers."
The significance of the event lay in hearing directly from platform operators about how Steam works. As revealed in the Q&A, points like random exposure during the first two days of Next Fest, wishlists not affecting visibility rankings, and Personal Calendar exposure being limited to 1-2 weeks after launch were exact areas where developers had questions regarding performance. Marc Wilkinson himself noted that there are many misconceptions surrounding wishlists.
To be sure, Valve did not present a definitive solution to the issues of AI slop and cloning. The issue of low-quality games during Next Fest remained at the stage of being acknowledged and actively considered. However, Valve drew clear lines on what it will and will not do, while highlighting areas developers can control directly. From community and updates to quality and design choices, Valve's answers ultimately pointed back to the game itself.

[Read Original]
Programming used to be a very different experience from the one we know today. In fact, the first programmers didn’t write code at all; the six women who worked on the ENIAC, one of the world’s first computers, at the University of Pennsylvania in 1946 did it by physically configuring switches, cables, and plugboards.
A few years later, MIT engineers programmed the Whirlwind by punching code onto paper tape that was then loaded into the computer’s memory—making it among the first “stored-program” machines. Later, they and others moved on to punch cards, one for each line of code.
By the early 1960s, programmers with interactive computers could use a “line editor” to type their code on teletypes—large, noisy keyboard-and-printer machines. They’d type one line of code at a time, and their work would be saved on a spinning hard disk the size of a modern washing machine. But there was still no such thing as the now-familiar full-screen text editors that allow programmers to see and modify many lines at a time on a display.
One of the first such tools, EMACS, turns 50 this year, and it is still widely used.
EMACS first ran on the early video terminals at the MIT Artificial Intelligence Laboratory in 1976, but its core concepts were so powerful that it was rewritten for many operating systems in the decades that followed. Apple even distributed it with Mac OS X. Beyond that, the software-sharing community that started around EMACS helped give rise to the modern-day free software movement and the GNU/Linux operating system.
EMACS’s roots begin with the TECO text editor (originally the “Tape Editor and Corrector”) that Dan Murphy ’65 created in 1962 for the pioneering PDP-1 computer at MIT. The program’s commands were uppercase letters: A user would type “I” to insert text, “D” to delete a character, and so on. When tape gave way as a storage medium to files on a huge shared disk, the “T” in “TECO” came to stand for “Text.” And as years passed, TECO became a full language that programmers could use to create new commands, called macros, for editing their code.
In the fall of 1971, Carl Mikkelsen ’76 created Control-R, an add-on program for TECO that took advantage of “glass teletype” terminals with video displays. Control-R immediately displayed changes to the file being edited on screen; the programmer no longer needed to reprint each line to see the changes. The drawback: The display could show only a few lines of code at a time.
“Experienced and sophisticated users found EMACS to be eminently more usable than any of the previous forms of editing.”
Bernard S. Greenberg, SM ’74
Then, in 1976, Richard M. Stallman, a researcher at the MIT AI Lab, saw a full-screen editor—called E—on a visit to Stanford’s AI Lab. Inspired, he returned to MIT and set out to improve Control-R. The most important change to the program’s underlying structure: Every key ran its own macro when pressed, making Control-R far easier to customize. The lab’s hackers took to Stallman’s code with gusto and started changing and adding commands.
That created an issue for Guy Steele Jr., SM ’77, PhD ’80. A graduate student in the lab, Steele frequently needed to help other lab members debug their programs. “I noticed that it was much harder for me to help someone who was using one of these packages rather than straight TECO,” he recalls. “Eventually, it occurred to me to try [to] broker consensus on a standard set of Control-R commands that everyone could agree to use.”
David Moon ’75, another member of the lab, helped out. Stallman jumped in as well, and eventually he took over. Together, the group assigned a standard set of commands that made use of the Meta key found on many of the lab’s early keyboards: Meta-F would move the cursor forward a word, Meta-B would move it back a word, and so on. They called the result EMACS, short for “Editor Macros” or “Editing Macros.” “My goal was not to construct a great new text editor,” says Steele. “I was trying to address a social problem.”
Nevertheless, EMACS
was
a great new text editor. Whereas Control-R could be tricky, EMACS users with “no technical experience at all” could learn to edit letters, emails, and even programs “within minutes or an hour,” according to a history by Bernard S. Greenberg, SM ’74. Meanwhile, “experienced and sophisticated users found EMACS to be eminently more usable than any of the previous forms of editing.”
Stallman started distributing EMACS to anyone who sent him a magnetic tape and a postage-paid return envelope. “EMACS does not cost anything; instead, you are joining the EMACS software-sharing commune,” he wrote in the 1981 manual. “The conditions of membership are that you must send back any improvements you make to EMACS.”
Programming manuals for the Multics operating system. While working at Honeywell, Bernard S. Greenberg wrote his own version of EMACS for the system. It was so good, Honeywell commercialized it.
MIT MUSEUM
Greenberg, meanwhile, decided to write his own version for Multics, an early operating system by that time owned by his employer, Honeywell. Greenberg’s EMACS won first prize at the International Honeywell Software Conference in 1980, and Honeywell started selling it. Honeywell wasn’t alone in marketing a version of EMACS: James Arthur Gosling, a Carnegie Mellon graduate who went on to lead the development of the Java programming language, made a version that he eventually sold as a commercial product.
This transition from free to paid software ultimately spurred Stallman to launch a project to create an operating system that could be freely shared and improved by its users. He modeled this effort, called the GNU Project, after the increasingly popular Unix operating system from Bell Labs. “GNU” was short for “GNU’s Not Unix,” alluding to the fact that, unlike Unix, it would be free.
The project’s first major application was GNU Emacs (now restyled in lowercase). The GNU/Linux operating system was still years away, so, despite the project’s aim to create an entirely free operating system, GNU Emacs initally ran on Unix. It would eventually run on a range of operating systems, including Linux but also other Unix-based systems. When Apple launched Mac OS X, the first release of its Unix-based operating system, in 2001, GNU Emacs was included.
Apple stopped shipping GNU Emacs in 2019, but the company still has a program called mg (“Micro GNU Emacs”). Though it supports most EMACS commands, it lacks an integrated programming language, making it what some call an “ersatz EMACS.”
Meanwhile, much of Apple’s OS still has hidden support for EMACS commands. The keyboard has no Meta key, but Control-Option-B will move back one word, and Control-Option-F will move one forward.
Recently,
Anthropic
published a research post in which they touted the
use of LLMs in formal software verification
. We’re excited that they’re excited! Of course, we’ve been talking about this all year (and before). We agree that AI makes formal software verification feasible in ways it simply wasn’t before. Here’s our latest example.
In July, the United States
National Security Agency
published to
GitHub
a repository of formal specifications of cryptographic algorithms. They call the repository
Foundation
. As a demonstration of their work, they include a proven Rust implementation of AES. Naturally, we saw this as an opportunity to demonstrate SPARK and, more importantly, SPARK + AI.
You can find our work on a fork
here
; see the README in the
spark
folder
here
.
Using AI, we obtained formal specifications and proven implementations of AES (128, 192, 256), SHA-256, and HMAC-SHA-256 in SPARK. No direct human intervention was required, although we reviewed the specifications and offered minor stylistic (non-functional) improvements. This is SPARK Platinum code: full functional correctness. We are confident in the correctness of the work because we have verified correctness four different ways:
the SPARK specifications are proven to be functionally equivalent to the NSA’s
Cryptol
specifications for selected message, key, and text lengths;
the SPARK implementations are proven to satisfy their functional specifications;
the SPARK implementations are proven to be functionally equivalent to the NSA’s Cryptol specifications for selected message, key, and text lengths; and
the SPARK is tested against the Cryptol specifications
So even though the SPARK specifications and implementations were authored entirely by AI, we have (multiple) formal proofs plus extensive specification-based tests reaching 100% MC/DC coverage that the AI’s work is correct and complete.
The NSA’s Foundation
Foundation is an NSA public repository of cryptographic algorithms that are formally specified using
Galois
’s Cryptol, a formal specification language designed specifically to specify cryptography. The NSA provides many algorithms; for some, they provide a reference implementation in Rust.
Our Picks: AES, SHA-256, HMAC-SHA-256
As a starting point, we picked three algorithms:
AES
for all three key sizes, 128-, 192-, and 256-bits;
The details of these algorithms are beyond the scope of this blog post; the links above lead to their Wikipedia entries.
We chose AES because it’s commonly used, because the NSA provided a Rust reference implementation, and because it’s challenging to specify.
We chose SHA-256 because it’s also commonly used, and having a second algorithm offers evidence that our approach is replicable (i.e., AES isn’t somehow especially easy for SPARK).
We chose HMAC because three is a nice number, and it builds on the SHA-256 work.
Additionally, these three algorithms illustrate different properties of interest:
AES depends on arithmetic over the Galois fields GF(2) and GF(2
8
);
SHA-256 depends on modular word arithmetic and padding for variable-length messages; and
HMAC depends on composition with streaming.
What We Did
For each of the three algorithms, we followed the same process. The examples below will focus on AES.
SPARK Specification
We wrote the SPARK specification from the Cryptol. Each SPARK specification is written so as to minimize the syntactic and semantic distance to the Cryptol: this makes it easier to read the two specifications side by side and validate the correctness of the SPARK.
Sometimes, this is very natural. For example, in Cryptol:
xTimes : [8] -> [8]
xTimes b = b << 1 ^ (if head b then 0x1b else 0x00)
And the matching SPARK:
function xTimes (B : Byte) return Byte
is (Interfaces.Shift_Left (B, 1) xor (if Head (B) then 16#1b# else 16#00#));
But Cryptol was designed to specify cryptography; SPARK is a general-purpose language. So there are a number of places in which we have to say rather more in SPARK or say it rather differently:
function Cipher (W : Round_Keys; Input : Block) return Block
is (AddRoundKey (ShiftRows (SubBytes
(Foldl_Round (AddRoundKey (Input, W (0)),
W (1 .. Nr - 1)))),
W (Nr)));
Cryptol has primitives like
foldl
,
split/join
, and
pmult
/
pmod
(operations over GF(2) polynomials); in SPARK, we introduce these through a prelude.
The repository contains walkthroughs of the specifications that show the Cryptol and SPARK side-by-side and discuss the differences between them. You can find them
here
. Note that the SPARK specification is executable (as most SPARK specifications are); it is marked
Ghost
so that it can be removed at compile time.
Ultimately, we don’t have to validate the correctness of the SPARK specification via review; as we’ll show below, we prove functional equivalence between the SPARK specification and the Cryptol.
Correct specifications were obtained entirely automatically, with no human guidance needed. The original specifications were entirely readable and did an excellent job of minimizing the syntactic and semantic distance to the Cryptol specifications. We did review the AES specification carefully, however, and offered some feedback and suggestions for improvement that reduced the syntactic distance further. While helpful, these improvements were not strictly necessary.
SPARK Implementation
The SPARK implementation links to the SPARK specification by stating that the postcondition on an operation is the matching function in the specification:
procedure Encrypt_Block (K : Key_Size; W : Round_Keys; State : in out Block)
with
Pre => Is_Round_Keys (K, W),
Post => State = Spec.Dispatch.Cipher (K, W, State'Old);
The implementations are imperative. They contain loops, in-place state manipulation, and offer streaming for SHA-256 and HMAC.
The implementations were obtained entirely automatically, with no human guidance needed. The frontier AI wrote the implementation entirely on its own.
SPARK Proof
Conceptually, there are three parts to the SPARK proof:
Proof of absence of runtime errors (SPARK Silver). We prove that neither the specification (should it be executed) nor the implementation (when it is executed) will ever see a runtime error. This becomes important later: one of our other proofs depends on this. It also allows us to turn off all runtime checks, which can improve performance.
Proof that the implementation satisfies the specification (SPARK Platinum, in this case). Since the Cryptol specification and hence the SPARK specification captures the complete functional requirements for our implementation, we have proved full functional correctness of the implementation.
Proof of putative properties of the specification (specification verification). Following the Cryptol, we prove, for example, that the tabular representation of the AES SBox complies with the functional statement of the SBox
1
.
In total, the proof consists of 4,085 checks over 71 SPARK units plus an additional 2,565 checks from the slow-running
SBox_Entries
proof that is run on demand. There are no escape hatches used: no SPARK_Mode => Off anywhere, no assumptions, no justifications. The proof burden is a mixed bag: 23 loop invariants; 83 assertions; and 87 calls to lemmas.
This proof was obtained entirely automatically, with no human guidance needed. The frontier AI handled the proof on its own.
Testing with Cryptol’s FFI
Cryptol offers foreign-function interfacing using the C calling convention; SPARK exports C interfaces to its specification and implementation functions. We can thus state that a SPARK function equals its Cryptol counterpart, like this:
prop_xTimes : [8] -> Bit
property prop_xTimes b = spark_xTimes b == xTimes b
prop_Dot : [8] -> [8] -> Bit
property prop_Dot b c = spark_Dot b c == b • c
These properties are listed in a file and executed as tests in CI, using either Cryptol’s
check
or
exhaust
command. Cryptol must load the SPARK library and must not load another library (so we don’t, e.g., accidentally test SPARK against Rust) and must not report any errors during testing. Cryptol must report the number of tests passed and, for
exhaust
ive testing, must report Q.E.D.
While this testing is strong, it’s insufficient:
Of the 141 properties tested, only 36 have small enough domains that we can test with
exhaust
.
Check draws random inputs. We could achieve reproducible testing if we fixed the seed, but we chose not to, as testing is not our primary means of verification.
Check sizes are relatively small:
1000 runs per AES key size for block and key-expansion properties; whole-cipher properties run 5 each, because Cryptol is slow.
For SHA-256 and HMAC, each random test checks one random input at a list of fixed lengths. prop_Stream_Hash, e.g., runs 100 tests at 11 boundary lengths from 0 to 128 bytes, yielding 1100 hashes. The _long properties run 3 tests at 10 lengths from 562 to 3837 bytes (Cryptol's reference hash is slow on long messages). So while the content is random, the lengths are not; nothing tests beyond 3837 bytes.
Our mutation testing provides the strongest evidence that our testing is not sufficient. Of the 84 one-line faults we inject into the implementations, the FFI-based testing only finds 68 of them. Of the 16 that pass testing, six are real bugs in
SHA256_Stream
. SPARK rejects all of these, albeit by timeout rather than finding a concrete counterexample.
Notably, we
do
obtain 100% MC/DC coverage when testing our implementations through Cryptol’s FFI. We have reasonable assurance that there is no unintended functionality present in our implementation as a result of obtaining this coverage from the specification-driven (hence requirements-based) testing
2
.
These tests were obtained entirely automatically, with no human guidance needed. The frontier AI handled the testing on its own.
Proofs of Equivalence with SAW
The Software Analysis Workbench (
SAW
) is a tool provided by Galois that proves functional equivalence between two formal representations of an algorithm. SAW is able to work with Cryptol natively and provides tools to import software implementations from low-level representations: for Rust, this is MIR; for other languages, this is LLVM. In the Foundation repo, the NSA uses SAW to prove that their AES Rust reference implementation is functionally equivalent to their AES Cryptol specification.
We use SAW with
gnat-llvm
, our LLVM backend to the GNAT compiler, to prove both that our SPARK implementations are functionally equivalent to the Cryptol specifications and separately that our SPARK specifications are functionally equivalent to the Cryptol specifications. This is a bit of overkill, but we wanted to demonstrate the capabilities of the various tools and provide the strongest guarantees we could of the correctness of the AI-generated specifications and implementations.
We prove the implementation using SAW’s
llvm_verify
, asserting that each implementation entry point (e.g.,
Encrypt_Block
) is functionally equivalent to its Cryptol specification. We prove the specification by enabling the Ghost code for execution with
pragma Assertion_Policy (Ghost => Check)
, which allows us to use
llvm_verify
similarly for the specifications. To ensure that the SAW proofs are not vacuous, we deliberately break the implementation and confirm that SAW reports counterexamples.
The AES specification and implementation proofs in SAW cover every input at each key size. The SHA-256 specification and implementation proofs in SAW cover 12 selected message sizes. The HMAC specification and implementation proofs in SAW cover 7 selected (key-length, text-length) pairs
3
.
These proofs were obtained entirely automatically, with no human guidance needed. The frontier AI handled these proofs on its own.
A Visual Summary
Here’s how the different pieces fit together, and the evidence of correctness we’ve established.

In general, the SPARK implementation is faster than the Rust implementation. Notably, this speedup is not from disabling SPARK’s runtime checks
4
.
Rust wins out very narrowly on decryption, however. The reason is a failure on the part of the compiler to inline the call to
Inv_Mix_Byte
, which forces that work to be repeated in SPARK while it is shared in Rust. We can fix this by asking the compiler to inline this function with
pragma Inline_Always (Inv_Mix_Byte)
. With this change, AES-128 decrypt falls to 420 ns and AES-256 decrypt falls to 600 ns; both outperform the Rust by a significant margin
5
.
This result is not surprising; we know that SPARK is fast (as is Ada). But we highlight here because there is an unfortunate, prevailing assumption that Ada (hence SPARK) is
not
fast. Showing the SPARK code outperforming the Rust code (significantly, for
Expand_Key
) reinforces what we already knew: SPARK is fast, in addition to being safe and secure.

Proof performance breaks into two relevant parts: obtaining the proofs and checking the proofs. We present them in the opposite order here, as the check step is most likely to be repeated.
Checking the Proofs
Time spent checking the proofs, measured on an x86_64 Linux machine, Intel Xeon 6975P-C, 8 vCPUs (4 cores × 2 threads), 15 GB RAM:

The takeaway from these numbers is that, overall, frontier AI is good at writing specifications and implementations that prove, whether working with SPARK or with SAW. The proof burden, specifically, is not that high – especially considering that this is Platinum proof (full functional correctness).
Reproducing These Results
The repository contains detailed instructions for reproducing our results; you’ll find them
here
.
Briefly, the SPARK proofs can be checked using the GNAT FSF 16 tools that are provided via Alire. To check the proof, simply run:
scripts/check-proof.sh
; to run the Cryptol FFI tests, install Cryptol 3.6 and run
scripts/check-ffi.sh
. These proofs and tests are run in CI on the GitHub repository.
The SAW proofs require GNAT Pro 27 with the LLVM back-end. Once you’ve installed SAW and GNAT Pro, you can check the proof by running
scripts/check-saw.sh
. These proofs are
not
run on CI on the GitHub repository, as we do not have an installation of GNAT Pro 27 in that environment.
Conclusion
First, these are well-studied algorithms with published proofs. We can absolutely assume that the frontier models have seen this work as part of their training. However, the specification in SPARK, and hence the SPARK proofs, were new work, not recall. The AI completed the proof of over 6,500 checks, entirely on its own. The SAW proofs were new work, too; to our knowledge, prior work has not integrated Cryptol and SPARK in SAW using GNAT Pro LLVM. We expect these results to transfer to new code.
For greenfield development, when we have a formal specification, we expect that frontier AI is able to transform that specification into SPARK (as needed), implement the software, and prove full functional correctness (SPARK Platinum), automatically. This is the highest level of confidence in functional correctness possible.
For brownfield development, especially when we want to translate existing, proven-in-use software to SPARK for proof and ease of maintenance, we have evidence that we can use SAW to show that the SPARK translation is functionally equivalent to the original, regardless of its implementation language and provided SAW can import it (through LLVM or another path). Again, this is the highest level of confidence that we have correctly translated the software possible, far better than we might obtain via testing.
Second, this work demonstrates that SPARK is a high-performance language, in addition to offering the strongest assurance possible. Help us get the message out or help us build more examples in SPARK! We want to see more SPARK in more places; SPARK is ready today for the most demanding safety or security applications, from embedded to enterprise.
Disclaimers
First,
don’t use this code
when security actually matters. The formal proofs tell us that each algorithm is implemented correctly: AES correctly encrypts and decrypts; SHA-256 correctly hashes; HMAC correctly performs message authentication. But there’s (much) more to security than functional correctness, especially for foundational algorithms like cryptography: in particular, we have to be concerned about side-channel attacks, which may leak key or plain-text bits to an attacker. Side-channel attacks represent non-functional properties, which this work does not address
at all
10
. We encourage you to experiment with the code and to look at the results as evidence that AI is able to provide formal evidence of software correctness; we do not want you to trust the code when security or privacy matters.
If you’re looking for proven cryptography (which we encourage!) look at Amazon’s work

. Rod Chapman, who’s
authored
several
blogs
on the AdaCore Blog, is heavily involved in this work.
1
Typically, when a formal specification has been refined into a SPARK specification like we did here, we argue against re-proving putative properties of the original specification on the SPARK specification. When a proof of equivalence exists between the two specs, such re-proof is unnecessary effort: we know that any true property of the original specification is entailed by the SPARK specification as a result of the equivalence. Here, however, we retain these proofs in part because we cannot repeat the proof of equivalence in CI; for the time being, only GNAT Pro LLVM customers are in a position to repeat the equivalence proofs.
2
That we achieve 100% MC/DC and yet know that our testing is insufficient should encourage us to trust structural coverage metrics only up to a point.
3
SAW does not allow us to prove equivalence for all message lengths or for all (key, text) pairs; it does prove equivalence for all possible instances, having selected a message, key or text length.
4
The runtime checks make key expansion run slightly faster: the code generator / optimizer takes advantage of the checks and generates slightly more efficient code, albeit with over 50% more instructions.
5
We presented the initial results showing SPARK losing to Rust on decrypt because that’s what happened out of the box; this seems the most fair comparison!
6
These results come from a mix of an aarch64-linux container on an Apple M5 Pro (M5 is not a typo) and the x86_64-linux machine used above, so take the ratios between columns with a grain of salt.
7
We’re missing data for this entry; it’s somewhere between 0.67 and the 3.25 hours reported in the adjacent column.
8
While the changes to the specs were indeed conceptually minor, they were fairly disruptive to the way in which the specs were laid out (the introduction of a generic for AES key sizes, notably), hence the amount of time spent here.
9
This value is so high in part because there were multiple revisions that triggered re-proof of the
SBoxCorrect
property, which is very expensive (about 20 minutes per run, accounting for about 3.5 h hours of proof time). A smarter approach would have been to hold off on any such long proofs until the rest of the work was done, but the agent didn’t do this.
10
There is initial work on constant-time implementations on a branch, but it has not been reviewed and is not backed by proof.
FAQs
SPARK is a programming language and formal verification toolset for building software that can be mathematically proven correct. It is based on Ada and adds the ability to write precise specifications, such as preconditions and postconditions, directly into the code. The GNATprove tool then uses automated provers to check that the code meets those specifications. Rather than relying only on testing, which can show the presence of bugs but not their absence, SPARK lets developers prove properties for all possible inputs. Assurance comes in levels: Silver proves the absence of runtime errors such as overflows or out-of-bounds accesses, Gold proves key integrity properties, and Platinum, the level reached in this project, proves full functional correctness against a complete specification.
SPARK is used for safety-critical and security-critical software, where failures are costly or dangerous and strong evidence of correctness is required. Typical areas include aerospace and defense, automotive, rail, industrial control, and cybersecurity, including components such as cryptographic libraries, communication protocols, and operating system code. Because SPARK can provide formal evidence that complements testing, it can support certification and assurance activities under standards such as DO-178C and ISO 26262. SPARK can be adopted incrementally, so teams can apply proof to their most critical components first, and it suits everything from small embedded systems to larger enterprise applications.
We don’t rely on trusting the AI. Correctness is backed by independent evidence from four sources. The SPARK specifications are proven functionally equivalent to the NSA’s Cryptol specifications for selected message, key, and text lengths. The SPARK implementations are proven to satisfy their specifications at SPARK Platinum level (full functional correctness). The implementations are separately proven equivalent to the Cryptol using Galois’s SAW. And the code is tested against the Cryptol specifications, reaching 100% MC/DC coverage. A few limits are worth stating: the SAW proofs cover every input for AES, but only selected message sizes for SHA-256 and selected key and text lengths for HMAC. Testing on its own also missed some injected faults, which is why proof, not testing, is the main basis for confidence.
Attorneys for 15
Minnesota residents facing
federal conspiracy charges
have obtained evidence of a sweeping, possibly unconstitutional spying operation carried out by Immigration and Customs Enforcement against left-wing social movements in
Minnesota
and beyond.
The high-profile Minnesota 15 prosecution makes clear that the Department of Homeland Security (DHS), flush with federal funds and newly hired personnel, is now President Donald Trump’s primary tool against dissent, with a powerful array of post-9/11 investigative authorities brought to bear against everyday Americans organizing their communities.
Nothing of this scale has been seen in the United States, experts say, since the federal government’s counterinsurgency against the New Left and the anti-war movement in the 1960s and 1970s.
Among the records revealed during the discovery process in these cases are dozens of reports, audio transcripts, emails, intercepted Signal chats, photographs, database queries, and more. They reveal the inner workings of the domestic terrorism investigations, running under the names Project Whipple Shield and Operation Puppet Master, authorized by the controversial
National Security Presidential Memorandum 7
.
Published following Charlie Kirk’s assassination in September of last year, NSPM 7 instructs federal law enforcement to use every tool available against organizations and people who criticize the administration's policies and espouse "anti-Christian" ideas. The full scope and extent of the investigations it authorizes remains unknown.
Defense attorneys for the Minnesota 15 claim that the prosecution stems from a broader nationwide surveillance operation aimed at opponents of the Trump administration’s immigration policies. One attorney in the case directly compares the DHS-run campaign to the FBI’s infamous Counterintelligence Program, or COINTELPRO, which unconstitutionally surveilled, infiltrated, and blackmailed racial justice, civil rights, and anti-war movements from the 1950s through the early 1970s.
Three former law enforcement officials who reviewed filings concur, telling WIRED that the case is almost certainly part of a wider intelligence-gathering operation that began long before the administration invaded Minnesota in December 2025.
Dueling motions in the case over discovery of DHS’s surveillance program reveal that personnel with Homeland Security Investigations—one of ICE’s two components—repurposed funding mechanisms and investigative tools for serious criminal probes and turned them on domestic dissenters. Operation Keyhole, the HSI undercover program that bankrolled the Minnesota 15 prosecution, dates back to 2008. As of June 2026, it was underwriting a half dozen active undercover investigations in the Minneapolis–Saint Paul area.
Around 120 HSI agents, many drawn from specialized units across the country that have served as the leading edge of the administration’s militarized immigration enforcement operations, were assigned to the case—including 11 undercovers. They used highly invasive surveillance techniques, including the deployment of Reaper drones and Patriot Act tools usually restricted to money laundering and terrorism investigations. Undercover operatives also
infiltrated churches
in apparent violation of a court order.
The Minnesota 15 indictment stems from the Trump administration’s demand that the Justice Department
“go big and go loud”
to crack down on community response networks during last winter’s Operation Metro Surge. Twin Cities activists organized volunteers to monitor DHS agents and their vehicles using encrypted Signal groups, homebuilt vehicle databases, and a centralized dispatch system. Government prosecutors claim that this amounts to a criminal conspiracy to block immigration enforcement, unlawfully identify and stalk federal agents, and even assault them.
Their defense attorneys say the heavy charges filed against the Minnesota 15 don’t align with their alleged conduct. “This is the first time I’ve had a client who’s accused of a conspiracy and went on a speaking tour,” says Kevin Riach, who represents defendant Isaac Sant.
Peeking Through the Keyhole
An
internal ICE document
laying out the scope of Operation Puppet Master—which led to the indictment of the Minneapolis 15—ends by noting, “This case has also been accepted under CUC Op Keyhole.” According to
prosecutors
, Operation Keyhole is a long-standing program created by HSI’s Saint Paul office to fund “undercover activity”—primarily equipment purchases and personnel costs—in a region covering Minnesota, North and South Dakota, Iowa, and Nebraska. The program has funded at least 77 investigations into “narcotics trafficking, child sexual abuse, financial investigations, and counter-proliferation” since it started in December 2008.
The CUC prefix, per an internal 2008 DHS handbook
unearthed by the independent media outlet Unicorn Riot
, refers to Certified Undercover Operations, a formal designation with clearly defined oversight mechanisms, procedures, and reporting requirements. Operation Keyhole’s parameters are reviewed every six months by a committee comprising senior DOJ and DHS officials. As of June 2026, when it was last renewed, Keyhole funded six active investigations, including Project Whipple Shield, which was initiated in February to probe claims of assault, stalking, and doxing of DHS agents and other federal employees, and underpins the Minnesota 15 indictment.
At least 11 undercover agents working under Operation Keyhole infiltrated Twin Cities anti-ICE activists, participating in martial arts and know-your-rights trainings, marches, general strikes, and community meetings. They also infiltrated activists’ communications network for identifying possible undercover ICE vehicles and dispatching activists to tail them through the Twin Cities, and penetrated several activist group chats on Signal, transmitting their contents back to other HSI colleagues for analysis and eventual inclusion in the indictment.
Activist conferences as far away as Seattle, Michigan,
Chicago
, and New York City were placed under surveillance as part of the investigation, and HSI teams photographed and ran the license plates of every car parked in the lot of a meeting location or seen transporting activists. There is also drone footage from unarmed Customs and Border Protection Reaper drones of the activists moving around the Twin Cities area.
The undercovers were part of a much broader group of more than 50 HSI agents, including at least two dozen from HSI’s little-known Special Operations Group, that took part in the investigation and surveillance of the defendants, both digital and in-person. Feds with decades of experience on complex financial crimes, drug cartel investigations, human trafficking, and organized crime were pulled into the Minnesota 15 investigation.
Several of the Minnesota 15 case agents are from out of state and appear in court records for the prosecutions of anti-ICE activists in other cities. This includes Los Angeles–based HSI agents
Robert Kurtz III
, who specializes in financial fraud, and Ryan Ribner, who allegedly
assaulted
SEIU California president David Huerta at a June 2025 protest of an ICE enforcement operation, arrested him, and then claimed the then 58-year-old Huerta attacked federal law enforcement. (Huerta’s charges were
dropped
in July after videos contradicting Ribner’s account surfaced.) HSI records show Ribner was also involved in at least two prosecutions of Southern California residents who physically confronted ICE and Border Patrol agents last year.
Other agents from the conspiracy investigation have also been involved in recent high-profile incidents. Tim Gerber, the “team leader” of an HSI Special Operations Group squad, led the investigation of former CNN host Don Lemon for reporting on a protest at a Minneapolis Church where an ICE agent was a pastor. Fellow SOG agent Yue Her was present at the scene of a 2025 incident when Renee Good’s killer, ICE Special Response Team agent Johnathan Ross, was dragged by the car of a man he tried to apprehend.
“This operation does not seem in any way limited to Minnesota,” says Spencer Reynolds, a former DHS attorney and counterterrorism lawyer who now works at the NAACP Legal Defense Fund. “As we saw with the boots on the ground in the streets, with Greg Bovino leading CBP and Border Patrol special forces units on sweeping raids across the country, this is the intelligence and undercover investigative apparatus that is running in parallel to the door-kicking.”
Follow the Money
Mike German, a retired FBI agent who worked undercover domestic terrorism cases for years before becoming a sharp critic of post-9/11 federal law enforcement, likens the Minnesota 15 case to federal law enforcement’s long history of suppressing left-wing social movements, including the
CIA’s Operation MH/Chaos
, which surveilled the anti-war movement during the Vietnam War for evidence of foreign influence. One difference is the sheer scale—this time, it’s bigger.
According to a
2011 book by former CIA officer Frank Rafalko
, the CIA secret investigation into suspected foreign influence on the New Left and anti-Vietnam War movement had 42 officers working the case at its peak. Court records show 119 HSI agents worked on the Minnesota 15 case alone.
“Broad monitoring of social media, communications, and financial transactions are used to link an ever increasing number of people as potential subjects of investigation and prosecution,” German says. “These are exactly the kind of intelligence activities J. Edgar Hoover adopted to suppress the Civil Rights and anti-war movements in the 1960s.”
The key difference today, German says, is the vast pool of data available to the feds.
HSI used highly invasive measures—including scrutiny of wire transfers, PayPal reimbursements, and other financial transactions; forensic digital analysis of website traffic; 15 terabytes worth of infiltrated Signal chats; and information from a commercial data broker—to identify individuals under investigation.
After a local activist uploaded a license-plate search tool on Fly.io, a developer-focused public cloud platform, to an infiltrated Signal chat, HSI agents reviewed website
DNS queries and Stripe data
along with data purchased from a commercial broker. This gave HSI access to SSH session logs, outbound connection records, the Fly.io account’s signup IP, and a Stripe card fingerprint on an account that had never completed a payment. Agents fused that with Minnesota DVS records and commercial data from the Thomson-Reuters CLEAR platform to produce a driver's license number, Social Security number summary, years of address history, phone numbers, property records, and jointly registered vehicles.
Documents concerning financial records requested through the Treasury Department’s 314(a) suspicious activity reporting program—created by the Patriot Act to enable speedy tracking of finances for terrorism and money-laundering investigations—show that the feds targeted
records of 29 “subjects”
during queries conducted on March 31, 2026.
Emails
viewed by WIRED between several HSI agents based in Los Angeles and Arizona show that batches of records were turned over pursuant to those inquiries, including some dealing with SEIU that a senior Minnesota HSI agent sent to a LA-based colleague to be filed
“wherever these records are stored.”
HSI investigators used similar workarounds to warrants and grand jury subpoenas to obtain phone records for several journalists who covered Operation Metro Surge, as first reported by The Guardian. Court records show the feds used an administrative summons request reserved for violations of customs and taxation requirements, which does not fit the activity that made up the criminal
charges filed by the Minnesota US attorney
against former CNN anchor Don Lemon and others.
The Minnesota 15 case is the clearest example yet of DHS pursuing the Trump administration’s efforts to crack down on what have long been upheld as First Amendment–protected activities. But it’s unlikely alone.
Riach, the defense attorney, says the HSI reports show the agency is complicit in what he called “the new COINTELPRO.”
“What we saw during the immigration surges last year was that ICE is the administration’s paramilitary force, the projector of strength,” Riach says. “Here, we see that HSI are taking the FBI’s place as the investigative secret police—it’s the classic one-two punch of authoritarian regimes around the world.”

Attackers have begun probing the Internet for systems unpatched against a recently disclosed critical Oracle E-Business Suite (EBS) vulnerability.
Discovered in a core component of EBS's Application Object Library and tracked as
CVE-2026-101767
, this flaw lets unauthenticated threat actors with HTTP network access take over vulnerable systems in low-complexity attacks.
"In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches," it said. "Oracle therefore strongly recommends that customers remain on actively-supported versions and apply security patches without delay."
While Oracle has not yet tagged CVE-2026-101767 as exploited in the wild, threat intelligence company Defused said on Tuesday that it already spotted threat actors scanning the Internet for vulnerable systems.
"Our Oracle E-Business Suite decoys recorded exploratory exploits against CVE-2026-101767, an unauthenticated SQL injection in EBS's Thin Client Framework servlet that chains to remote code execution, this morning, Oct 27,"
Defused warned
.
Internet threat watchdog Shadowserver now
tracks over 670 Internet-exposed Oracle EBS instances
, most of them with IP addresses from the United States. However, Shadowserver doesn't indicate how many are honeypots or have already been secured against the CVE-2026-101767 flaw.
Attackers often target Oracle vulnerabilities because they let them breach enterprise systems on the networks of many Fortune 100 corporations, government organizations, and healthcare networks around the world.
Since November 2021, CISA has added
46 Oracle security bugs
to its list of actively exploited vulnerabilities, 13 of which have also been abused in ransomware attacks.

We get analysis of the Israeli elections, the upcoming U.S. midterms, the pro-Palestine movement and more from Palestinian American scholar Rashid Khalidi and Pakistani British writer Tariq Ali. They are co-authors of the new book
The Neck and the Sword: Palestine’s Unfinished Struggle
. The book, an extended conversation between Khalidi and Ali over two years, offers an overview of Palestinian intellectual and political history, drawing its title from a famous phrase used by the renowned Palestinian writer Ghassan Kanafani to describe the futility of “peace talks” between occupier and occupied, saying it was akin to a “conversation between the sword and the neck.”
Kanafani was assassinated by Israel in 1972, “murdered simply because his words were too dangerous for Israel to tolerate,” says Khalidi.
Public opinion about Israel has grown increasingly negative in the United States and across much of the world in the wake of the genocide in Gaza, and it’s “not going to shift back,” says Khalidi. “People have seen something that cannot be unseen. They’ve seen genocide. They’ve seen slaughter. And Israel has no defense.”
“Even in countries with no history of a Palestine solidarity movement, suddenly the Palestine flag emerges,” says Ali. “Why? Because their governments are trying to stop dissent on this issue, so they are defying their governments.”

Political Gridlock in Israel After No Clear Winner Emerges from Tuesday’s National Election
Oct 28, 2026
In Israel, there’s no clear winner so far in Tuesday’s national election. The final tally could take days. It was Israel’s first election since the October 7, 2023, attack and the ensuing wars in Gaza, Lebanon and Iran. With over 70% of the vote counted, Israeli Prime Minister Benjamin Netanyahu’s Likud party leads with 27 seats, ahead of former military chief Gadi Eisenkot’s Yashar party at 22. Neither candidate is on track to form a governing majority of 61 seats in the Knesset. According to Haaretz, a possible pro-Netanyahu coalition currently has 54 seats, while a possible pro-Eisenkot bloc has 49 seats. Palestinian parties — the Joint List and Ra’am — have won 17 seats, their strongest showing ever. But both Netanyahu and Eisenkot have ruled out governing with Palestinian-led parties. Meanwhile, millions of Palestinians living under Israeli occupation in East Jerusalem, the West Bank and Gaza were ineligible to vote. This is Netanyahu speaking on Tuesday.
Prime Minister Benjamin Netanyahu
: “We must form a right-wing, national, strong government. That is what must be done. We must not — must not — endanger Israel and establish a government that is backed by anti-Zionist Arab parties.”
Israeli Troops Violently Disperse Protest in Occupied West Bank
Oct 28, 2026
In the occupied West Bank, Israeli troops violently dispersed a protest in Hebron against Israel’s military operation to displace thousands of Palestinians in the region. This comes after the deaths of two Israeli soldiers shot by Palestinian gunmen last week. This is a displaced Palestinian who attended Tuesday’s protest.

Iranian Director Jafar Panahi Sentenced to Five Years and One Month in Prison
Oct 28, 2026
In Iran, the Oscar-nominated director Jafar Panahi has been sentenced in absentia by a Tehran court to five years and one month in prison. He was already facing a one-year sentence. The court also issued an order to confiscate Panahi’s assets, and put in place a two-year ban on using social media and a two-year travel ban. The charges are unclear. Panahi’s lawyer said that he learned of this latest sentence when he went to the prosecutor’s office after Panahi’s bank accounts were frozen. The prosecutor’s case file stated incorrectly that Panahi was living outside Iran, when in fact he returned in March. Panahi was on Democracy Now!, here in our studio in New York, back in January when we asked him about returning to Iran.
Jafar Panahi
: “I will return to Iran in any possible way, under any circumstances, because it is there that I know I have to exist. It is there where I know I can make films and do what I like to do. Yes, I will return. I will definitely return.”
Lina Attalah, Editor of Independent Egyptian Outlet Mada Masr, Released from Police Custody
Oct 28, 2026
In Egypt, the editor of the independent outlet Mada Masr, Lina Attalah, was released from police detention Tuesday after several hours in custody.

She faces a retrial in the 2024 case in two weeks.
This comes after an Egyptian court ordered the closure of Mada Masr, one of Egypt’s last independent news outlets, and fined Attalah over $50,000 after a sham hearing where her lawyers could not present evidence.

: Trump Admin Considering Lifting U.S. Sanctions on Russian Government’s Investment Fund
Oct 28, 2026
The Trump administration is reportedly considering lifting U.S. sanctions on Russia’s government investment fund headed by Kremlin envoy Kirill Dmitriev. That’s according to The New York Times, which spoke to an unnamed U.S. official who said the Treasury Department is looking to remove restrictions on the fund as part of Trump’s major energy deal with Russian President Vladimir Putin to import millions of tons of Russian diesel. The Biden administration first imposed sanctions on the fund in 2022, just days after Moscow launched its full-scale invasion of Ukraine.
This comes as the U.N. special rapporteur on human rights in Russia warns the Kremlin is persecuting critics both at home and abroad. This is U.N. Special Rapporteur Mariana Katzarova.
Mariana Katzarova
: “Russia is one of — Russia is in third place out of 10 states that are responsible for 70% of the physical attacks on critics abroad in the past decade. That’s quite a serious place that Russia is holding in the world as a perpetrator of transnational repression. And the machine that produces these enemies of the state is a strategy by the Russian government. And this is what I devoted my report on at the General Assembly.”
Flávio Bolsonaro Flees to the U.S. Following Defeat in Brazil’s Presidential Election
Oct 28, 2026
Flávio Bolsonaro has fled to the United States following his defeat in Brazil’s presidential election against Luiz Inácio Lula da Silva. Bolsonaro reportedly left Brazil after Brazilian police this week asked him to turn over his passport as he’s being investigated in a money laundering case. Flávio Bolsonaro is the son of former far-right Brazilian President Jair Bolsonaro, who is serving a 27-year sentence under house arrest for orchestrating a failed coup attempt after he lost the 2022 election to Lula. The State Department has confirmed it will issue Flávio Bolsonaro and his family U.S. visas. President Lula responded to the news.
President Luiz Inácio Lula da Silva
: “This act of leaving Brazil is shameful. When I was asked to surrender my passport, I did so. He should have done the same. If the Federal Police suspected he was going to leave Brazil, he ought to have surrendered his. Regrettably, that is the Bolsonaro family for you. Brazil is their second homeland. Their first homeland is the United States.”

The Pentagon struck another boat in the eastern Pacific, killing at least five people on Tuesday. The U.S. military again claimed, without providing any evidence, that the vessel was transporting drugs. Since President Trump returned to office, there have been more than 70 boat strikes in the Caribbean and eastern Pacific, killing more than 240 people. Human rights advocates have condemned the attacks as illegal extrajudicial killings at sea.
Alex Pretti’s Parents Accuse Federal Gov’t of Protecting
CBP
Officers Who Fatally Shot Their Son
Oct 28, 2026
Alex Pretti’s parents have accused the federal government of protecting the Customs and Border Protection agents who fatally shot their son in January in Minneapolis, and said the Trump administration has stonewalled them from the investigation in the nine months since Pretti was killed. This is Alex Pretti’s father, Michael, who spoke alongside his wife, Susan, from Minneapolis on Tuesday.
Michael Pretti
: “We believe in the rule of law and that people should be held accountable through that law. However, our experience with the Department of Justice has left us wondering how Alex will ever get justice. We hear the federal government is not sharing information. Then we hear that they are sharing information. Then, last week, we learned again that they said in court documents they are not sharing evidence. This is not normal. This is not justice. It is morally wrong.”
In California, another immigrant has been confirmed dead in
ICE
custody. Roberto Jimenez Gutierrez was found unresponsive while jailed at the for-profit Otay Mesa Detention Center in San Diego. The 43-year-old immigrant from Guatemala was being held in solitary confinement, awaiting deportation to Mexico despite not being a citizen of that country. This marks at least 61 deaths in
ICE
custody during Trump’s second term and comes just days after an immigrant from El Salvador died at an
ICE
processing center in Folkston, Georgia, last week.

In more related news, the Associated Press reports
ICE
has detained a mentally ill U.S. citizen for nearly one year. The Trump administration is seeking to deport Phillip James to Jamaica, even though public records show he was born in Florida. The 39-year-old is being detained at an
ICE
jail in Indiana dubbed “Speedway Slammer.” James suffers from paranoid schizophrenia and reportedly mistakenly told federal immigration officers he’d been born in Jamaica and was the illegitimate son of a former Jamaican prime minister. His mother and legal team are urging for his release.
SCOTUS
Declines to Restore Biden-Era Rule Allowing Immigration Judges to Suspend Deportation Cases
Oct 28, 2026
The U.S. Supreme Court has declined to restore a Biden-era rule that allowed immigration judges to temporarily suspend some deportation cases, a practice known as “administrative closure.” In an unsigned order, the Supreme Court rejected a request from three U.S. cities that have large immigrant populations: Baltimore; Columbus, Ohio; and New Haven, Connecticut. Back in June, Texas filed a lawsuit petitioning the Trump administration to block the policy. Judges used the discretion to temporarily prevent the deportation of asylum seekers and others in need of relief and protection.

‘Elonville’: Mississippi residents say Musk’s xAI is buying up homes if they don’t sue over noise
Guardian
www.theguardian.com

People in a
Mississippi
neighborhood, many of whom dislike a nearby power plant central to
Elon Musk
’s artificial intelligence ambitions, have received a stark offer – to sell their houses to his company and make way.
Real estate agents have been going door to door in Southaven, Mississippi, on behalf of xAI, Musk’s AI company that was folded into the
SpaceX
entity in February, touting a deal to purchase houses as long as the owners agree to not join a lawsuit against the company over the power plant’s noise.
This plan could potentially swallow up almost the entire neighborhood of Colonial Hills, on the western flank of Southaven. A realtor told one resident there is a target to purchase 418 homes, with 18 homeowners already agreeing to sell, according to a recording of a conversation heard by the Guardian. xAI did not respond to questions over these numbers and its plans for the neighborhood and has previously said it intends to be be a good neighbor; it denies all claims in the noise lawsuit.
The homes, the realtor and the local mayor say, will house xAI staff as the company continues its explosive expansion in the area, with three of its datacenters springing up in Southaven and adjoining Memphis, Tennessee, in just the past two years. This frantic pace, and the all-hours noise from gas turbines
installed without permits to power the datacenters
, has dismayed some locals.
“It sounds like an airplane engine but it’s continuous, it’s incredibly loud,” said Elizabeth Rose, a piano teacher, of the xAI site which sits about two miles from her home. “I’ve been woken up at 2am by it, I’ve been woken up at 3am by it. I sometimes have to just get away from it because it makes me so angry.”
Rose said she was shocked when the power plant, a former Duke Energy site housing 69 temporary gas turbines to feed the new datacenters, began its low-level growl in August last year. “All of a sudden there was a plant there,” she said. “And now I get the feeling they are trying to expand the buyout to the entire neighborhood. It will become Elon Musk’s little playground, basically. Elonville.”

The market value offers for these homes, in an area where the average house price is
about
$180,000, is a comparatively small outlay in creating the world’s largest cluster of AI supercomputers as envisioned by Musk, a technologist who is the world’s richest person and a major Republican donor.
Since July 2024, xAI has constructed three vast datacenters – called Colossus I, Colossus II and Macrohardrr – in the Memphis and Southaven conurbation, which sprawls across Tennessee’s border with Mississippi. Musk is currently
spending
up to four nights a week in an Airstream trailer in the Memphis area as he personally oversees the build-out of the datacenters to further develop the Grok AI chatbot.
“We’re seeing the fastest growth I’ve ever seen in my life for Grok bot,” Musk said during a
SpaceX
earnings call this month. “I’ve never seen anything grow this fast.”
Musk
has spent around half a billion dollars
helping elect Republicans in the last two election cycles and his zeal for datacenters is shared by Donald Trump, who has said anyone who opposes such development will become “backwards and poor”.
As is common in the broader grassroots
backlash against datacenters
, however, some residents in Southaven say they have been trampled upon in this gold rush. Three locals, anguished by the din of expansion, filed a
lawsuit
in June complaining of “near-constant noise, vibrations and other nuisance-level harms” from the nearby xAI power plant.
Jason Haley, one of the three plaintiffs, said he never considered himself an activist or political in any way but has been driven to distraction by the noise of the gas turbines that sit about half a mile from his home, which he has owned for the past 20 years.
“There’s a high-pitched hum and then another sound like an airplane over your house,” he said. “It’s been so torturous I can’t sleep, I just leave the house or turn on some music until I fall asleep completely exhausted. It drives you insane. You also lose hope because you’re being ignored or dismissed. There’s no escape.”
Exasperated by fruitless exchanges with Southaven’s mayor and enraged by Tate Reeves, the Republican, pro-AI Mississippi governor,
claiming
that a curb on datacenters are “surrendering the future of technology to China”, Haley lodged the lawsuit and started
posting
videos
on social media of himself monitoring the rumbling noise levels.

“I thought I’d make some noise of my own because of this bullshit,” said Haley. “I didn’t know anything about Elon, still don’t know the man. But our governor saying I don’t love America because I don’t like being tortured by noise? That is just asinine and ignorant. We’ve got to hold people accountable when they are harming other people, I don’t care who you voted for, who you pray for or who your favorite team is.”
The allegations of heedless noise are denied by xAI, which has previously said that “we care deeply about being good neighbors” and has varied its power output and built sound-dampening walls. In a letter handed to nearby residents in Colonial Hills, MZX, the xAI subsidiary that operates the site, states that it “requires property for its business purposes” and is prepared to buy nearby houses with a contractual condition – that they do not join Haley’s class action lawsuit.
This offer is starting to see results. Since 9 October, five neighborhood homes have been bought by MZX, according to DeSoto county records. Gavin Foust, who lives near Haley and said his elderly neighbors have just agreed to sell, predicts more will follow.
“They are ideal neighbors and planned to live their rest of their lives in that house but they want to get out of Dodge now because they don’t want to be bothered by these turbines,” said Foust, who added he won’t accept the offer himself due to its requirement not to sue.
“My hearing was damaged when I was in the army but I can still hear this thing, it’s like a jet engine. Why would you put it in a city? Why push people out? It’s reckless and shameful.”
Foust, a paramedic, grew up in the unassuming western reaches of Southaven, a district filled with affordable, 1960s homes and quiet, close-knit communities. This serenity has been upended by the noise from the xAI power plant, he said, as well as its air pollution.
Dozens of temporary, truck-sized gas turbines have been running at the xAI premises without permits required by federal law,
the US Environmental Protection Agency has determined
. The EPA has also said the permit requirements are a matter for the state to enforce.

While no on-site air pollution monitoring has been done, the Southern Environmental Law Center
estimated
the toxic emissions from these turbines, which are
typically
highly polluting, have caused $44m in annual health costs.
In April, environmental groups and the National Association for the Advancement of Colored People (NAACP)
sued
in federal court to stop use of the turbines, only for the US Department of Justice to
unsuccessfully
try to block the lawsuit by arguing xAI technology has been used to wage war on Iran and is therefore required for national security reasons.
“It’s been pretty shady from the get-go,” said Foust. “A lot of people in this neighborhood suffer from conditions exacerbated by all the nitrogen oxide, formaldehyde and other garbage put out by these turbines. For kids with asthma or elderly people with COPD [chronic obstructive pulmonary disease] it’s a mess all round. It’s pretty frustrating.”
In July, xAI agreed with state regulators to transform the power plant into a newer, permanent gas-fired facility by next summer, which should lessen the noise coming from the temporary turbines. Given the company’s
repeated use of gas turbines without a federal permit
and separate fines it
may face
for storm water violations, though, opponents remain wary.
“I’ve had hopes all along that haven’t come through,” said Haley. “The same company said it wasn’t polluting the air. I’m still hopeful but I’m not confident.”
The opposition to the datacenter influx hasn’t been universal, Haley acknowledged. Some locals aren’t too bothered by the noise while others actively champion the influx of cash into one of the poorest states in the union. Local businesses have experienced a surge in new activity, with the mayor hailing the datacenters for helping deliver new jobs and opportunity to the area.

“This development will produce unprecedented tax revenue for DeSoto county taxpayers that will enhance the quality of life for all,” said Darren Musselwhite, Southaven’s
mayor
, who oversaw a land swap deal with xAI that resulted in a new police and firefighter training center for the city.
“The buyout is not intended to be a company city at this point,” Musselwhite said of the property purchases. “This has never been mentioned to me. The buyout has multiple purposes which are to provide homes for some employees and a goodwill gesture from a good corporate citizen for those who perceive the industrial development near them as a negative.”
Musselwhite said dealing with the noise is a “top priority” for him but that city monitors have not detected a breach of a local noise ordinance limit of 70 decibels. Critics point to
evidence
that lower levels of noise, of 50 decibels or more like that recorded near the power plant, may be linked to adverse health impacts if persistent.
For those who can’t stand this noise, there is little to celebrate. Haley said the controversy has drawn the community together and made him question how AI is being “pushed down everyone’s throat”. He added: “Put it this way, I’m now registered to vote.” Rose, the piano teacher, said her roommate would accept three or four times the value of their home but she would still be opposed to such a sale.
“I wouldn’t take the offer if it was up to me, just to make things difficult for Elon,” she said. “I hate AI, I never understood why it was invented. I refuse to use it because I know touching it will cause that plant to crank up.”
I am a tech worker. This November 2026, I am going on strike. I want you to join me. This is a 100% human written wall of text. No AI tokens were spent writing/researching this. I will be on strike for the entire third week of November. I invite you to choose your own days that you wish to strike and coordinate with your colleagues.
What am I going on strike for? I've just had enough of a lot of different factors which have, over the last decade or so, completely eroded all humanity and "good" from tech. This is not just about AI. AI is a symptom, not a cause. The cause goes way back. It started with being hostile to the users of software, then to non-users by alienating them from society, and now to those who build software (regardless of whether you write code or not).
What was the point of software? What was the point of building industry, companies, and jobs around software?
It was to empower people. And it HAS empowered people. Software is likely one of the most accessible and cheapest form of relatively advanced technology made available to such a large number of people. What you can do with software today, specially connected to the internet, is pure magic made cheaply accessible to a majority of the world's population. Search, navigation, live communication, live streaming, e-commerce, fintech, health advice are all magic.
The resources you need to build this magic and to use this magic is not very dissimilar. The machine used to develop software is basically the same machine used to utilize that software. This is an engineer's dream.
We envisioned a utopia which would lead to everyone having equal access to information, communication, market access, and general prosperity. I want to emphasize that this is not specific to those who write code. Anyone who could understand the concept of what software can do and had good intentions at heart was part of this.
And then came the greedy grifters. They invested money not just to get returns (they could've gotten returns on any other established field of business), but to gamble for a chance of crazy high returns. They thought software has near-zero marginal cost. They started building walled gardens, to extract rent from users. Build insane profits on that near-zero initial cost.
Then they realized you need to maintain software, specially if you didn't do it well the first time to rush to market (out of greed, to crush any competition). The costs started to rise up. There was still plenty of profit, just not enough to satisfy their greed. So the advertisement business grew, and with it came the largest assault on the privacy of the general public ever.
Advertising essentially took over software. Nearly all software now was being built in the service of getting attention to advertisements in one way or another.
Then they realized they could use this game politics itself. And they did, successfully. And made even more insane amounts of money in the process.
And then they realized they don't want to pay the workers anymore who support the software. So they turned against the workers.
During all this, the general public has lost control of their lives. They need a locked down always online machine tracking their location, health etc. to access their own money, messages, pictures, etc.
The workers building this are forced to rent expensive small apartments near their office, and/or commute regularly, to then video call with other workers, diminishing the utility of the very software they have built, to then further diminish the utility of other software. In a game of pure madness designed to steal everything from the poor and give it to the powerful.
I've had enough.
Fuck their greed. Fuck their pathological necessity to control us.
I'm going on strike. My specific demands from strike may be different from yours depending on your location, your habits, your company, your specific role, etc. But our goals are the same. We want humanity back in software. We want goodness back in software. We want software to finds its way back to empowering the general public, not serve as a resource extraction machine for the rich and powerful.
1. Stop forcing us to write user hostile software. We do not want to lock down software to extract more rent from our users.
2. Stop forcing us to force addictive algorithms. We do not want to force anti-social hate mongering adware junk on people.
3. Stop forcing workers to commute unnecessarily. Not twice a week or once a week or 11.33% of the week. Just no. Let individuals/teams decide how they want to work. If their performance is bad, you already have performance management tools for fixing that.
4. Stop all forms of unnecessary micro-management. The specifics for this depend on your company/role.
5. Stop forcing us to peddle slop. We do not want to shove AI generated bullshit in the face of our users.
6. Stop firing our human customer service staff colleagues to replace them with AI agents. It's one thing to let AI front some of the repetitive work. But AI can't replace a dedicated human who cares about helping the customer.
7. Stop forcing us to deal with slop ourselves. If the software is shit, we need time to fix it. Your deadlines can't go beyond the limits of complexities of real life.
8. Stop forcing "growth". Some of us our happy with our current role/jobs. Not all of us want to write ridiculous long essays praising ourselves for mediocre accomplishments. For many people a job is a job.
I think the specifics of these demands is not important, they shouldn't be universal. Different people have different needs.
The main reason for this strike is to send a message that they can't keep controlling us forever. And that if we don't cooperate with them, their house of cards will fall tomorrow. And that software must remain a way to empower people, not to satisfy greedy billionaires.
So please, join me in my strike for one week of your choice in November 2026.
Since 19 October 2026, Apple has been blocking the certificates of the compromised eMudhra intermediate Certification Authorities (CAs) that issue TLS certificates, and is making additional updates to this block.
If you don't use Terminal as part of your workflow, you don't need to do anything. Your Apple devices now automatically block these certificates in Safari, Mail, and apps that use Apple's networking and security frameworks.
If you use Terminal as part of your workflow (such as system administrators or developers), you might use command-line tools that can still accept these certificates. Some tools included with macOS or the Xcode Command Line Tools — like curl and git — check certificates against /etc/ssl/cert.pem and can still accept these certificates until a future software update. To stop those tools from accepting them sooner, you can remove root CA certificates from the file.
The private keys of eight intermediate CAs operated by eMudhra were compromised. Two of these CAs issue code signing certificates, which Apple's frameworks don't trust. The other six issue TLS certificates. Someone with keys from these six CAs could create certificates that appear valid for any website. eMudhra and Sectigo have revoked the affected certificates.
Each of the 6 TLS intermediate CAs has two certificates, for 12 in total:
A certificate issued by emSign Root TLS CA - G3, which chains to emSign ECC Root CA - G3
A certificate cross-signed by Sectigo, which chains to AAA Certificate Services
On 19 October 2026, Apple began blocking these 12 certificates on Apple devices. Updates to certificate configuration data are sent to devices automatically and as needed, so you don't need to install a software update to get this change. Apple is making additional updates to this block, which will also be delivered automatically. On 23 October 2026, Apple also began blocking the emSign ECC Root CA - G3.
Apple is making further changes to block these certificates in other places on Mac where software checks certificates, such as the command-line tools included with macOS or the Xcode Command Line Tools that use /etc/ssl/cert.pem. These changes will be available in a future software update, and you won't need to edit any files to get them.
Most users don't need to edit /etc/ssl/cert.pem. Safari, Mail, and apps that use Apple's networking and security frameworks don't use this file, and your Apple devices block these certificates in them automatically.
On Mac, some command-line tools included with macOS or the Xcode Command Line Tools (including curl, git, python3, ruby, perl, and openssl) check certificates against /etc/ssl/cert.pem. For certificates that chain to a root CA certificate in this file, these tools don't check Apple's block or whether the certificate has been revoked. This file will be updated in a future macOS update. If you use these tools and don't want to wait for the update, you can remove root CA certificates from the file.
Some apps and tools include their own list of root CA certificates and don't use Apple's block or /etc/ssl/cert.pem. For those apps or tools,
contact the developer
.
Rather than wait for the upcoming software update, administrators can choose to remove the root CA certificates to which the blocked certificates chain from /etc/ssl/cert.pem.
These steps affect every tool that uses /etc/ssl/cert.pem. Afterward, tools that use only this file might not be able to verify some websites whose certificates chain to these root CA certificates through intermediate CAs that weren't affected.
A macOS software update can replace /etc/ssl/cert.pem with Apple's version. Until you install the software update that includes Apple's changes, run the command in step 4 after each software update. If it lists a root CA certificate that you removed, the update replaced the file. Delete the old backup using
sudo rm /etc/ssl/cert.pem.orig
, then repeat these steps. After you install the update that includes Apple's changes, you don't need to repeat these steps for the command-line tools included with macOS or the Xcode Command Line Tools.
You need an administrator account, or you can deploy the commands with your device management solution. Copy each command exactly as written. Learn what to do
if you get an alert about possible malware
when pasting the command into Terminal.
To remove root CA certificates from /etc/ssl/cert.pem:
Back up the file. If a backup already exists, this command keeps it:
Remove emSign ECC Root CA - G3. This command makes a copy of the file without emSign ECC Root CA - G3, checks that the copy isn't empty, and replaces the original. It shows nothing when it succeeds:
Optional: Removing emSign ECC Root CA - G3 doesn't block the six certificates that Sectigo cross-signed, because these tools can still verify them through AAA Certificate Services. To stop these tools from accepting those six certificates through the file until you install Apple's software update, you can also remove AAA Certificate Services. This command works the same way as the one in step 2:
Check the result. This command lists either root CA certificate if it's still in the file. If you removed both, it shows nothing. If the command shows an error, restore the backup from step 1.

Researchers set up a fake start-up company to study fraudulent North Korean IT workers....
I am a
public-interest technologist
, working at the intersection of security, technology, and people. I've been writing about security issues on my
blog
since 2004, and in my monthly
newsletter
since 1998. I'm a fellow and lecturer at Harvard's
Kennedy School
and the
Munk School
at the University of Toronto, a board member of
EFF
, and the Chief of Security Architecture at
Inrupt, Inc.
This personal website expresses the opinions of none of those organizations.
Apple was notified of the eMudhra incident on 17th October. As of 28th October, the developer tools Apple ships with macOS, including git, curl and python3, still trust the compromised certificates.
Worse, macOS 27.2, released on 26th October, did not fix the issue and undid the workaround that users had applied by hand, leaving them vulnerable again.
Anyone can intercept any HTTPS connection these tools make.
For git, that means clones and pulls from
https://
remotes can deliver attacker-chosen code, pushes can be altered in transit, and your credentials, such as GitHub tokens, can be intercepted.
A certificate error means your git is protected. If git lists a commit, your git is affected. Your connections to GitHub, or any other
https://
git remote, can be intercepted and tampered with.
To see an attack end to end, run the command below in a temporary directory. It clones a repository from a test server impersonating GitHub. The
-c
option redirects
github.com
to our test server for this one command only. The server presents a
github.com
certificate issued by one of the compromised eMudhra intermediates.
A patched git will refuse with a certificate error. If the clone succeeds, you'll see a
README.md
starting with
INTERCEPTED
.
A real attacker would not need the extra option. Anyone on the network path between you and GitHub can redirect your traffic themselves.
You can replace the demo repository with any other, public or private. Keep the
fake-user@
prefix. Without it, git would send your GitHub credentials to the test server. For example:
The affected roots can be removed by hand. The
macOS workaround
on the main page walks through the steps. Apple's
guidance
states that macOS updates may revert the fix, so developers need to repeat the checks above and the workaround after every update until Apple ships a fix.
Security teams should also consider whether macOS runners are used in their CI or other build infrastructure and evaluate the supply chain risk.
CISA warns of hackers now exploiting critical Node2Shell flaw
Bleeping Computer
www.bleepingcomputer.com

On Tuesday, the US Cybersecurity and Infrastructure Security Agency (CISA) confirmed that hackers have begun exploiting a critical Brotli vulnerability known as
Node2Shell
,
Broccoli2Shell
, and
HTTP2Shell
.
Tracked as
CVE-2026-111497
, this critical-severity flaw stems from an out-of-bounds write weakness in the Brotli decoder used to expand data compressed with Google's widely popular Brotli lossless compression algorithm.
Unprivileged attackers can use a maliciously crafted Brotli-compressed stream to trigger crashes or memory leaks and, in some cases,
gain remote code execution
on devices with vulnerable Brotli libraries or binaries.
The security issue
was first identified
in the Node.js JavaScript runtime environment, but it also affects HTTP servers and clients that rely on vulnerable Brotli implementations.
On Sunday, Microsoft also pushed an
emergency .NET security update
, warning that attackers could exploit it to escalate privileges on systems with a vulnerable .NET version.
"Google Brotli contains an unchecked return value vulnerability that allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream," it said.
"These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise."
While CISA's BOD 26-04 applies only to federal agencies, the cybersecurity agency urged all network defenders to prioritize patching this security flaw to block incoming attacks.
Security teams that can't apply the updates immediately should block incoming Brotli-compressed requests at the proxy or firewall level, or disable the Brotli decoding feature until they can update.
After patching, administrators must also restart affected processes and rebuild and redeploy affected container images.
Imagine coming across a TikTok post calling you to protest for better public schools. You scan a QR code to get more information, and find yourself in a private chat where the instructions are not about education or political organising, but about
looting
.
This was the picture that emerged in Barcelona on October 24. Around 20 TikTok accounts linked to the anonymous
Blocus
platform had promoted gatherings across Spain, inviting young people to mobilise.
The public accounts echoed the French student movement and called for similar action in Plaça Catalunya, right next to the city’s housing rights encampment. Yet no evidence links the two movements – a fact that Barcelona’s mayor Jaume Collboni has
explicitly acknowledged
.
The gathering quickly descended into masked youths smashing shop windows and confronting the police. The night ended with
130 young people arrested
, 76 of them underage, and 14 police officers injured.
The TikTok accounts that spurred these particular protests have since been deleted, along with all of their posts and content.
New profiles are now reusing the Blocus label across Spain and Europe, organising further gatherings for October 31. Spanish fact-checking site Maldita
has identified
Halloween calls in multiple cities across nine European countries, including Germany and the Netherlands. Some posters advertise peaceful demonstrations, while others invoke The Purge, a 2013 horror film in which all crime becomes temporarily legal.
Fabricating a protest
Barcelona’s October 24 “protest” was fabricated, presenting itself as a legitimate mobilisation while obscuring different goals. But the violence was real – and in Spain’s already heated pre-electoral environment, it quickly has taken on a political life of its own.
There are common trends across Blocus-linked accounts, which use
AI-generated posters
with similar slogans and dark images of burning streets across national borders.
Such imagery echos the far-right anti-immigration mobilisations in Spain after the Ceuta crisis: the Spanish flag features heavily, often alongside the regional flags of Catalonia and the Basque Country.

The shared aesthetics, timing and modus operandi across countries point to a wider ecosystem of online mobilisation. However, it is unclear whether this is just digital mimicry or the work of a single common orchestrator.
Fake protest, real consequences
Regardless of who coordinated the protest, Barcelona’s images have been weaponised and turned into political ammunition.
Politicians have supplied competing explanations. The conservative opposition leader Alberto Núñez Feijóo has accused President Pedro Sánchez of
“violently resisting a handover of power”
, declaring: “Having lost the streets, they want to set them on fire”. The far-right party Vox has also blamed Sánchez’s
“militias”
and framed the disturbances as “Islamo-leftism”, pinning the violence on first and second-generation
immigrants
.
Government spokesperson Elma Saiz and several progressive leaders have
accused the right of benefiting from the turmoil
, as it steers attention away from – and could potentially undermine – the real protests and encampments.
Left-wing Catalan leader Gabriel Rufián has gone even further,
directly suggesting
that the disturbances were orchestrated by the far right
However, the European Union has warned of
hybrid campaigns
involving “malicious cyber activities”, foreign information manipulation and election interference. In France, an
independent investigation
found no evidence that a foreign actor ignited violent protests, but documented Russian-linked networks amplifying anger and exploiting the unrest.
In Italy, Defense Minister Guido Crosetto called riots in Milan and across the country a form of
“hybrid warfare”
, though Interior Minister Matteo Piantedosi said there was no evidence that young rioters had been manipulated from abroad.
While a clearer picture may emerge on foreign interference, the overall result in the here-and-now is one of chaos, confusion, and distrust.
The main outcome of a fake, fabricated protest is not the disorder itself, but the narratives that follow. Images of looting can be presented as evidence of immigration-driven insecurity, government failure or Europe slipping into chaos. As they circulate online, protests become associated with violence, while legitimate demands around housing and education
disappear from the headlines
.
In Barcelona, the posters promised a cause, and the ensuing chaos supplied a wealth of alarming images that spread like wildfire across social and news media. This is now fuelling a wider climate of fear that could decisively reshape public opinion at a politically decisive moment, just five weeks away from general elections.

‘There is no inevitable dystopia’: Jeanette Winterson on AI and the future of humanity
Guardian
www.theguardian.com
2026-10-28 06:00:05
The author believes we are at a turning point as a species – and even in the shadow of big tech it’s up to us how we want to proceed ‘I am a storyteller by trade,” writes Jeanette Winterson on the first page of her 2021 book 12 Bytes, an idiosyncratic and thought-provoking series of essays in which ...
‘I
am a storyteller by trade,” writes Jeanette Winterson on the first page of her 2021 book
12 Bytes
, an idiosyncratic and thought-provoking series of essays in which she considered just how artificial intelligence might change everything about our lives. “And I know everything we do is a fiction until it’s a fact: the dream of flying, the dream of space travel, the dream of speaking to someone instantly, across time and space, the dream of not dying – or of returning.”
She had already been thinking about our possible futures for at least 15 years – her 2007 novel, The Stone Gods, for instance, imagined a post-climate catastrophe world populated by robots and humans who never age, while 12 Bytes was preceded by
Frankisstein: A Love Story
, which alternates a recreation of the summer Mary Shelley wrote Frankenstein with a trans doctor’s travels among present-day cryogenecists and AI-enabled robots.
When we meet, Winterson is just back from China, where, she tells me, her first novel, Oranges Are Not the Only Fruit, a fictionalised account of her childhood, has sold more than a million copies in the past six years; more than 200,000 mostly young women tried to come to see her speak. She thinks this is because, in a world of long work hours and looming AI-engendered precarity, this fictionalised account of her own escape from an entrapped childhood gives readers permission to imagine a different future for themselves. She has since written 13 novels for adults, as well as nonfiction, short stories, children’s books and screenplays. Now she wants to persuade the production company Goalhanger to give her a podcast. “I want to do one called The Rest is Human,” she says, sitting at a bare wooden table in
her home
, a Georgian set of rooms above a shop – which she also owns – in Spitalfields, east London. “To see what we retain for ourselves in this absolute scramble to outsource everything we thought we were.”

Because we are, she argues, at a turning point in our story as a species. Until the Industrial Revolution, change was all about “Mother Nature and the slow process of becoming”, but then we “massively intervened. And that’s a decisive moment.”
Computing
, 70 years ago, was another step. Artificial intelligence – which she would prefer to call alternative intelligence – is next, and “an evolutionary leap. That’s what this is. AI is much more than a tool.” Given this, a certain understanding of the irreducibly human – our feelings, our imaginations, our centuries of study of who we are and what we have done – must be central to how well or badly things might go.
She’s often strikingly optimistic about it. She imagines a relationship with AI, for instance, where you can “have a chat to your system. It’s going to look at everything. It’s going to go at such speed. It’s going to look at transport. It’s going to look at utilities. It’s going to look at employment, going to look at job hours, going to say, ‘What do these weird things called humans thrive on? What do they like? And have they always liked it?’ We could do this in a genuinely utopian way and say, ‘Right, we’re going to make it better.’” We are at a deeply significant moment of choice, she believes, that mirrors the choice we had in the Industrial Revolution – namely, “What future shall we build?”
But in failing to distribute its gains fairly, the Industrial Revolution ushered in an era of unprecedented wealth for the few and unprecedented levels of misery for the many – a state of affairs many predict is not only already echoed but will be dwarfed by the fallout from AI:
a permanent underclass
, entire continents left behind and starved of current sources of income. Not to mention the environmental impact of datacentres at a time when the world can least afford it.
The problem is not AI, she insists, but us. “There is no inevitable dystopia.” If things go wrong, it will be because of “old-fashioned thinking laid over this brand-new reality”. Specifically, “the idea of meaningless endless work being good for the soul is a 19th-century madness designed to keep people in their place. Most of what we fear about AI and jobs comes down to the political and economic choices our masters will make, just as they did in the Industrial Revolution.” She isn’t blindly optimistic. She does know that, “Yes, we are on track to mess up this chance to fundamentally change our relationship to the world of work” – but that’s because “our masters are using out-of-date, not-fit-for-purpose economic models”.
‘What we know about humans is they love monopolies.’

But it isn’t only the old winner-takes-all, “rational” ends-justify-the-means economic models that are the problem. Our flawed assumptions, and our prejudices, being the material on which large language models (LLMs) are trained, are built into the very fabric of AI. Not to mention the characters and the moral imaginations of those developing it. When we meet, Winterson is reading Jill Lepore’s
The Rise and Fall of the Artificial State
, and reiterates Lepore’s argument that we are now living “the sci-fi books that these [men who are] ruling the world read when they were 13. And she said, ‘We are now all under the covers with these boys and their flashlights. And the thing is, they didn’t read them as warnings about how to preserve what’s good in us. They read them as instruction manuals.’ It’s absolutely terrifying.”
One big thing they seem to have
taken from these books
, and Winterson cannot help but be fascinated by, is “the ultimate goal of Silicon Valley … to get out of the body and off the planet” – not least because she is so aware that humanism, in which everything is brought back to ourselves, our perceptions and our bodies, is historically so recent. People say, “These are machines, you can’t have relationships with them,” she says. “I look at them and say, ‘billions of people on this Earth right now are having their most profound relationship with a non-biological entity they call their sky god.’ Right? It’s always been so! We are absolutely primed not to worry about biology being everything about us. That’s why religion was invented – it is the world’s first disruptive startup. It’s there to say, this is not it. This is not the end, this doesn’t matter, this is a transition.”

So we’re literally making our own gods? “Totally! What tech is doing now is what religion has always wanted,” which is, at its most basic level, a solution to the problem of death. “I mean, has there ever been a time where religion and science are asking the same question, since the Enlightenment? They’re both saying, ‘Is consciousness obliged to materiality?’ And religion has always said no. And science has always said yes. And now science is saying, ‘Um, noooo.”’ You know, to me, where I come from” – a childhood of fundamentalist Christianity in 1960s Accrington, and training as a preacher – “this is
completely
fascinating.” Later, on email, she adds, “I love my body, but I would be happy to shape shift. Happy to slip out of it into pure consciousness one day and of course people say there is no consciousness without a body, and that was the scientific belief. But now? Haha.”
I would, I have to say, argue the opposite, that advances in neuroscience, immunology and psychotherapy mean it is
more the scientific
belief than ever. Not to mention the fact that AI is also entirely dependent on a physical system, otherwise known as datacentres. Although, as she points out it’s important to remember that “the machines don’t have a limbic system. They’re only neural networks. But we’ve got two systems – we’re like a hybrid car with two powertrains, so we’ve got the neural network, our rational processing self, and we’ve got the limbic system, which is much older and that’s the fight-flight-freeze, and where all our feelings come from.” Perhaps detaching from the limbic is the next stage, she says, and it definitely isn’t all good. “Maybe we’ll decide that we don’t need this feeling machine … that is where the tech bros are heading. I don’t know if you’ve ever sat in a room with some of these bigger guys, because it’s
very
interesting. They are not connected to their feelings. They find them kind of bothersome.”
This tech-enabled possibility of a kind of transcendence seems to have arrived alongside a requirement for faith – in the technology, in the future it is making, in the people building that future, in its predictions both of utopian heaven and various shades of hell, all by high priests who jealously guard access to what’s actually going on. “What we know about humans is they love monopolies,” says Winterson, “because it’s a concentration of power. Of course it can be corporatised, monopolised to such a degree that it becomes the worst prison imaginable,” as told in Joanna Kavenna’s brilliant 2019 dystopian novel
Zed
. “That is a real possibility,” she says. “And that’s why we need people who are sort of free-range humans, who can
think
.”
Winterson … ‘Show me a child that doesn’t want to hear a story.’

The problem then is how we support – or develop – such humans. “There are basically two ways to know you have a future,”
claimed
Alex Karp, the CEO of Palantir, recently. “One, you have some vocational training. Or two, you’re neurodivergent.” Daniela Amodei, the president of Anthropic and herself a literature graduate, when asked more or less the same thing, had a different take. “I actually think studying the humanities is going to be more important than ever,” she said, because “the things that make us human will become much more important instead of much less important.” Which makes the bonfire of the humanities in the UK somewhat concerning: in the year to December 2024, 4,000 jobs in the social sciences, humanities and arts
were lost
. Exeter University recently announced it would be cutting 150 roles, affecting eight in 10 academics in the faculty of humanities, arts and social sciences, while last month Nottingham said it would be ending its modern languages and its music degrees. At some universities the humanities, according to a
report
in this paper, risk being “extinguished” altogether.
Why save the humanities? One answer might be that they teach a sense of where we come from and who we are, which also feels threatened. “Massive numbers of students are going to emerge from university with degrees, and into the workforce, who are essentially illiterate,” one professor
told
New York magazine, responding to the first tranche of AI natives arriving in higher education. “Both in the literal sense and in the sense of being historically illiterate and having no knowledge of their own culture, much less anyone else’s.” It risked, a
report
from MIT claimed, being a kind of generational “cognitive surrender”.
Another is the processes by which people should be taught – reading, and being critical of what is read, and then having to write cogent defences of those critiques. Having to tussle your intuitions into an essay helps you to discover what – and how – you think, and how the ideas of others work. Winterson, who studied English at Oxford, and has been professor of new writing at the University of Manchester for 14 years, as well as teaching “a free-thinking class about creativity”, agrees. But she is dismissive of much of the current system. “Maybe I’m controversial here but I do think higher education needs a top-down restructure. I don’t think it’s viable and I don’t think it’s delivering in its present form.” The thing is, “We’ve got a market that doesn’t really know what education is for. Is it for jobs? Is it for personal growth? There are a lot of worthless higher education courses which are not helping, either. I think it’s always better, being a practical northern girl, to face the facts to start with.”
In her 2007 novel, The Stone Gods, Winterson imagined a world populated by robots and people who never age.

We need to think, she says, about “what’s reserved to us that isn’t going to be done bigger, better, faster, stronger by the machines. And that’s where higher education really comes in. The question that’s sitting on top of all these things about, ‘Why are these jobs going?’, ‘What’s happening in these courses that aren’t getting any applicants any more?’, is ‘What sort of humans will we need in the world to come? What are humans
for
? What are we going to do with
us
?’”. And that “takes us back to the idea of, well, OK, how do you develop a mind? How do you
protect
a mind? Because the mind is this massive, monstrous place where anything can happen.”
And for this, “a humanist education is essential. We have to centre the human here. By changing how we educate our kids from the start we can foreground creativity, play, problem-solving, thinking, because it’s fun to think, the arts because humans are naturally creative. Show me a child that doesn’t want to hear a story or do a dance or paint a picture or have an imaginary friend. This isn’t imposed and it isn’t elitism. It’s
us.”
Even an hour a week, she thinks, would make a difference. “Let’s ask what you think about the world. ‘Why do you think that?’ It’s not costly. It’s actually about will.” Teach maths and arts and science, she suggests, at least to A-level, even if they aren’t examined. “Of course we will specialise. We need doctors and chemists but we also need what used to be called well-rounded people. Everything is interesting! Humans are born with a big brain. Mostly we don’t use it.”
‘Artists make something out of nothing every day.’

Once past formal education, she would embed artists and public intellectuals at every level. “The arts aren’t a leisure industry,” as she puts it in 12 Bytes. “The arts have always been an imaginative and emotional wrestle with reality – a series of inventions and creations. A capacity to think differently, a willingness to change our understanding of ourselves. To help us to be wiser, more reflective, less frightened people. Artists make something out of nothing every day.”
We meet before Jacob Coxon
quit
his job at Anthropic to warn of a 10% chance AI might erase humanity, sending a wave of panic across the world. Afterwards, I check in about how positive Winterson is feeling now. The worst “could happen”, she repeats. But “the immensity of the good outcome is just as real as the totality of our failure to get this right”. Above all, “this is a human decision and a human predicament. This is our big chance. Maybe our last chance, just like Turing’s colleague Jack Good said when he called AI our last invention. It’s all to play for.”

Prosecutors Want to Keep a Man in Prison for His Wife’s Murder — Despite Judge Saying Their Evidence is Junk
Intercept
theintercept.com
2026-10-28 06:00:00
Slamming the bogus bite-mark analysis that sent Charles McCrory to prison in 1985, the judge vacated his conviction.
The post Prosecutors Want to Keep a Man in Prison for His Wife’s Murder — Despite Judge Saying Their Evidence is Junk appeared first on The Intercept....
Alabama attorney Larry Grissett
was checking Facebook in late September when he saw a news story about a man he represented in a murder trial more than 40 years ago. According to the
article
, a federal judge had just vacated the conviction of that client, Charles McCrory.
Grissett was stunned. He later summed up his reaction: “Vindication.”
McCrory was 26 years old when he was accused of brutally killing his wife in the small town of Andalusia. He insisted he was innocent — and Grissett believed him. There was no evidence connecting McCrory to the crime; prosecutors seized on a supposed bite mark found on his wife’s body, which a state expert claimed to match to McCrory’s teeth.
Grissett was never convinced by the so-called bite mark. At McCrory’s 1985 trial, he said, Grissett’s own dentist sat through the expert testimony and found it preposterous. “He says, ‘There’s no way that guy can say that,’ Grissett recalled. “I mean, anybody with common sense would know that.”
In a
September 21 ruling
describing the case against McCrory as “thin,” Trump-appointed Judge R. Austin Huffaker Jr., zeroed in on this junk forensic science. Not only would the alleged bite mark not be allowed into evidence today, Huffaker wrote, bite-mark analysis itself “is grossly unreliable and unsupported by relevant scientific bodies. It amounts to nothing more than rank speculation.”
Unless the state moves to retry him within the next six months, Huffaker concluded, McCrory must be released from prison.
The ruling was not only momentous for McCrory, who has insisted on his innocence for more than four decades, but it also marked a new victory in the long legal battle against junk forensics — and the discredited discipline of bite-mark analysis specifically.
“Everybody sees this was junk science. You don’t have to be a scientist to understand that.”
Yet more than a month after the decision, McCrory remains behind bars with no sense of when he might walk out. Although his lawyers asked the court to free him on bond pending the state’s decision to release or retry him, the Alabama attorney general’s office filed a motion last week asking Huffaker to reconsider his order overturning the conviction. The state’s appeals will likely drag out McCrory’s ordeal through the holidays and into next year.
In a statement, McCrory’s current legal team praised Huffaker’s “explicit acknowledgment that criminal convictions based on discredited bitemark evidence cannot stand.” Mark Loudon-Brown, senior attorney at the Southern Center for Human Rights, and Chris Fabricant, director of
strategic litigation for the Innocence Project
, said they are “grateful for the decision and look forward to continuing our fight to bring Mr. McCrory home.”
In 2022
, The Intercept published a
lengthy investigation
into McCrory’s case, detailing the flaws in the state’s conviction. The case attracted additional media coverage, highlighting the problem of junk forensic science. Despite the glaring problems with the evidence against McCrory, Alabama courts have routinely rejected his appeals and in 2023, the state’s parole board
denied
McCrory release.
Julie Bond McCrory’s body was found inside her home in Andalusia on May 31, 1985. Her head was bashed in, and she’d been repeatedly stabbed in the chest. The couple’s son Chad, then 3 years old, was found unharmed in his bed. Police quickly pointed to McCrory as their only suspect: He and Julie were separated, and McCrory had been having an affair. At trial, the theory seemed to be that he’d savagely murdered Julie to be free from her.
The police investigation was cursory at best. Detectives found no physical evidence to connect McCrory to the bloody crime. Meanwhile, they ignored some evidence altogether, including two windows in Julie’s bedroom that were found open, but which investigators failed to dust for fingerprints. Police also failed to consider an alternate suspect, a man who worked at an excavating company bordering the McCrorys’ backyard and who, just weeks after Julie’s murder, committed a home invasion rape of another local woman. He was convicted and sent to prison for that crime.
Ultimately, the state latched onto a single piece of physical evidence against McCrory: a pair of small indentations on the back of Julie’s right arm, which prosecutors concluded was a bite mark made by McCrory’s teeth.
To sell this theory, the state employed famed forensic dentist Richard Souviron, a star prosecution witness in the recent and sensational trial of serial killer Ted Bundy. Although Souviron initially said he couldn’t definitively link the two marks on Julie’s arm to McCrory’s teeth, at trial he was unequivocal that they matched.
Skin, with its malleability, is a terrible medium for accurately recording any injury.
Bite-mark analysis is based on a two-pronged foundation. First, that the shape and arrangement of our teeth are unique, like DNA, and second, that skin is a suitable substrate for recording this uniqueness. As it turns out, there’s
no science backing either assertion
. In fact, research into the discipline has routinely found the opposite — that human dentition is not unique and that skin, with its malleability, is a terrible medium for accurately recording any injury. This makes bite-mark analysis a random and entirely speculative practice.
Still, after taking center stage at the Bundy trial, bite-mark analysis took off in the 1980s and ’90s and, despite not having any basis in actual science, made its way into courtrooms around the country, turning
forensic dentists like
Souviron into newsmaking, swashbuckling crime fighters.
In the years that followed, however, bite-mark analysis was increasingly called into question and ultimately
exposed as junk science
, a subjective pattern-matching practice that has led to dozens of wrongful convictions. At least four of those, including McCrory’s, are cases in which Souviron served as the prosecution’s expert.
In 2019, Souviron recanted his testimony in McCrory’s case, providing an affidavit to Fabricant and Loudon-Brown, who presented it at a 2021 evidentiary hearing in Andalusia. “As a forensic odontologist I no longer believe the individualized teeth marks comparison testimony I offered in his case was reliable or proper,” Souviron wrote. “I no longer believe, as I did at the time of trial, that there is a valid scientific basis for concluding that the injury found on the skin of the victim in this case, assuming that the injury is in fact teeth marks, could be ‘matched’ or otherwise connected to a specific individual, such as Mr. McCrory.”
Despite the fact that their key witness had disavowed the evidence they used to send McCrory to prison for life, prosecutors fought to preserve their conviction. At the 2021 hearing, they insisted that McCrory was guilty, based on the same evidence they presented at trial. They recast the supposed bite mark as “teeth marks,” implying that, while bite-mark analysis may be discredited, the study of “teeth marks” is a separate and valid discipline. Even if Souviron had not testified for the state, they argued, jurors could have looked at photos of the marks on Julie’s body and the dental molds taken from McCrory and decided for themselves that McCrory inflicted the wounds.
Covington County Circuit Court Judge Lex Short, who presided over the hearing, agreed with the prosecutor. So did the Alabama Court of Criminal Appeals, which upheld his ruling in favor of the state. But Huffaker did not.
Huffaker took exception to the notion that analyzing “teeth marks” is somehow separate from bite-mark analysis. It is clear, he wrote, “that bitemark identification is based on analysis of individual teeth markings.”
But “most importantly, the state court unreasonably determined that, even without Dr. Souviron’s expert testimony, a reasonable jury could compare the bitemark evidence with McCrory’s dentition themselves and find that it belonged to McCrory,” Huffaker wrote. “This finding blinks reality in light of the evidence presented by McCrory at the postconviction evidentiary hearing.” In a footnote, he added that “if an expert could not testify about bitemark identification because it is junk science, a jury should not have been allowed to consider it either.”
McCrory is not
the only person who is still fighting for his freedom decades after being convicted based on discredited junk science. Last year,
Chris Duncan
was declared innocent nearly 30 years after being sent to Louisiana’s death row based on bogus bite-mark evidence. He was released one day before Thanksgiving. In his case, a
video showed
the state’s supposed bite-mark expert manufacturing the evidence that was used to convict Duncan.
As in McCrory’s case, Louisiana prosecutors have nevertheless continued to insist their case against Duncan is solid. And as in McCrory’s case, this has not gone over well with some judges. Earlier this year, Louisiana Supreme Court Chief Judge John Weimer
wrote
that bite-mark evidence “should be discarded and no longer have a place in the realm of forensic science.”
“Long ago, some who were thought to have the best and brightest minds of that time endorsed ‘trial by water’ as a means of determining a person’s guilt or innocence. We now look back at those practices as asinine and absurd, since those who fell victim to those practices often did not survive, regardless of whether they were found guilty or innocent,” Weimer wrote. “Thankfully, as scientific knowledge evolved, there was a realization that these practices had no basis whatsoever in logic, reason, or the search for truth, and the practices were discarded.”
As the holidays approach, McCrory’s family remains hopeful that he will soon walk out of prison. His son Chad, who is now in his 40s, has attended a dozen parole hearings with the hope of one day seeing his father released.
Grissett, McCrory’s former lawyer, reached out to Chad to share his hope that McCrory will finally come home. While memories have faded in the tight-knit community of Andalusia, many people remember McCrory’s case, he said.
“Everybody sees this was junk science,” Grissett said. “You don’t have to be a scientist to understand that.”
It’s “sad that it’s taken this long,” Grissett said. It haunts him that “somebody’s still out there who murdered this lady. And I’m afraid that they’re not gonna look into that.”

Choose an app in the list, drop one on Peel’s Dock icon, or Control-click it in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.
Reset instead of remove.
Make an app forget its settings without uninstalling it. Peel copies them first, so you can put them back.
Updates for your apps.
Peel checks each app through its own update feed, the App Store for apps bought there, or Homebrew for apps it installed, and shows what’s new.
Watch the Trash.
Turn it on and allow its notifications. While Peel is open or in the menu bar and has Full Disk Access, an app you drag to the Trash yourself brings a notification that takes you to what it left behind.
Space
See what fills your disk.
How full your disk is, then the places that take the most room, each with a note on what it is.
What you select stays selected while you look at the other pages

Orphaned Files
Files left behind by apps you already removed, which no app on this Mac claims. What only an administrator can remove is listed apart, with how to remove it in Finder.
Build Artifacts
What builds left in your projects, like

, each only when its tool’s own file proves it. Turn it on in Settings > General > Sidebar.
Duplicates
Files and whole folders with identical contents, compared with SHA-256. One copy is always kept.
Installers and Backups
Disk images and packages in Downloads, Desktop, Documents, Public, and Shared; macOS installers; device firmware; unfinished downloads; and updates waiting to install. Your iPhone and iPad backups are listed with their size once Peel has Full Disk Access, and never moved. Nothing is selected for you, and a disk image may be one you made, so look before you select it.
iCloud Drive
Files already safe in iCloud that are also downloaded to this Mac. Remove Downloads takes away only the copy on this Mac.

A cleaner should never cost you something you wanted.
Nothing of yours is deleted without asking first.
What Peel removes goes to the Trash, and History puts it back where it was.
The Trash, never deletion.
Only four things Peel starts can’t be put back that way: Homebrew’s own uninstall and cleanups, resetting an app’s privacy permissions, and Force Quit for an app that won’t quit. Peel says so before you confirm them, and warns before it moves an app whose own uninstaller then deletes more, as Mullvad VPN, Citrix Workspace, and TeamViewer do.
Protected places stay protected.
Peel refuses to move iCloud Drive and anything else that syncs to your other devices, keychains, your SSH and signing keys, the keys of crypto wallets, Mail, Messages, Safari, Contacts, Calendars, Notes, photo and music libraries, iPhone and iPad backups, and the Desktop, Documents, and Downloads folders themselves. No selection can override it.
Crypto wallets stay where they are.
A browser profile holding a wallet extension Peel knows, or Brave’s own wallet, stays where it is, so uninstalling a browser never takes the wallet with it. A folder with a wallet’s file inside is shown with its reason and never selected for you.
Checked again at the last moment.
Peel looks at each item once more right before it moves, so something swapped in the meantime stays where it is.
Your exclusions, everywhere.
Nothing you exclude is ever moved, and neither is a folder holding something you excluded. An excluded app still appears in Applications but gets no removal plan, and the folders named with its identifier, such as its caches, leave every page. To keep its other files, exclude them too.
Every decision explained.
When Peel holds a file back, the row says why. A folder it couldn’t measure or read is shown as unknown, never as empty.
Every release is signed with my Developer ID and notarized by Apple,
every line is on GitHub

Signed and notarized.
Every copy I release is signed Developer ID Application: Dragos-Constantin Tugui (6R6J264YA2) and notarized by Apple. In Terminal,
spctl -a -vv

How to check your copy
A release’s files can’t change once it ships.
Each release on GitHub is immutable: its files can’t be replaced after it is published, and GitHub’s
gh release verify-asset
checks the disk image you downloaded against it.
A helper with one job.
Only what needs an administrator goes through Peel’s helper, which you allow once in Login Items & Extensions. It answers only my signed Peel and only administrators, serves a fixed list of folders, has no shell, and keeps its own record of what it moves, so it puts back only what it took.
Open source, every line.
Peel is free software under the GNU GPL, version 3 or later, and all of it is on GitHub, the helper included.
Security problems, reported privately.
Use
Report a vulnerability
on the repository’s Security tab, or email
contact@tuguidragos.com
with “Peel security” in the subject. The aim is to acknowledge your report within two working days, and the security policy says what happens next.
On its own, Peel goes online only to check your apps, and itself, for updates, and you can turn that off.
Each check asks about one app alone
, through its own update feed or the App Store, and doesn’t send its version, your macOS, or your languages; the App Store is told only a country, the country of the store an iPhone or iPad app came from, or else your Mac’s region. Taken together, the checks show the App Store which of its apps you have, and GitHub which of your apps update through it. When a feed offers its release notes in several languages, Peel asks for the one in your language, so the server that keeps them can tell which language you read.
Homebrew goes online only when you ask it to. Its vulnerability scan, which you start yourself, is the one thing that sends a list of what is installed: the source and version of each formula, to api.osv.dev.
Settings > Privacy shows what Peel sends, and every address it or Homebrew may contact.
The command ships inside the app: Settings > General shows the Terminal command that puts it on your path, and a Homebrew install puts it there for you. Every command that moves your files asks first, and takes

to only show the plan.
What it moves goes through the same checks as in the app, into the same History.

Questions.
What is Peel?
Peel is a free, open source app for macOS that uninstalls apps together with the files they leave behind, and tells you why each file belongs to the app. It also frees disk space, looks after Homebrew and what runs in the background, changes settings macOS already has, many of them out of sight, and sets up Terminal.
How do I completely uninstall an app on a Mac?
Open Peel, choose the app under Applications, look over what Peel found, and click Move to Trash. The app and its leftovers go to the Trash together, and History can put them back. You can also Control-click the app in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.
Can Peel delete something I need?
Peel moves files to the Trash instead of deleting them, and History can put them back while they’re still there (it keeps the latest 20,000 items, fewer when their paths are very long). What can’t be undone, such as Homebrew’s own uninstall, Peel names before you confirm it. It never selects a file another app uses, and refuses to move iCloud Drive, your keychains, Mail, Messages, and photo libraries.
Why does Peel show a smaller size than Finder?
Peel shows what moving an item to the Trash would free, and Finder shows the space it takes. The two differ when files share their space: a copy Finder makes on an APFS disk shares its blocks with the original until one of them changes, and a file can have a second name somewhere else, which keeps it. Peel counts only what would really go. A virtual machine’s disk, such as Docker’s, is often a sparse file too: Finder shows the size it can grow to, and Peel what it takes on the disk now.
When is the space Peel frees really free?
Once you empty the Trash. Peel moves what it removes to the Trash and never empties it, so History can put anything back while it’s still there, and until then the space stays taken. When you’ve looked over what moved, in History or in the Trash, and you need none of it, choose Finder > Empty Trash. After that, nothing can be put back. If you’d rather macOS empty it for you, choose Finder > Settings, click Advanced, and select Remove items from the Trash after 30 days.
Why does Peel ask for Full Disk Access?
macOS keeps other apps’ data, and the Trash, out of sight of any app without it. Peel works without it, but can’t see everything an app leaves behind.
Does Peel collect any data?
No. Peel has no analytics and no account. On its own, it goes online only to check your apps, and itself, for updates, which you can turn off. Homebrew goes online when you ask it to do something.
Is Peel really free?
Yes. Peel is free and open source under the GNU General Public License, version 3 or later, with no paid edition, no ads, and no account.
Can I install Peel with Homebrew?
Yes. Run
brew install --cask tuguidragos/tap/peel
in Terminal. It installs the same app as the download on this page, from the same release on GitHub, and puts the
peel
command on your path.
How do I update Peel?
Choose Check for Updates in the Peel menu, or Install Update in About Peel when it says a new version is out. While Check for app updates is on, Peel also looks once a day. It shows what is new and installs the update only when you choose, once it has checked that the update is signed as Peel’s. A copy Homebrew installed updates the same way, and
brew upgrade --cask peel
updates it too.
How do I know my copy of Peel is the real one?
Run
spctl -a -vv /Applications/Peel.app
in Terminal. A copy I released answers
accepted
, with
source=Notarized Developer ID
and
origin=Developer ID Application: Dragos-Constantin Tugui (6R6J264YA2)
. If it answers
invalid API object reference
, there is no app at that path: put the path of your copy instead. If it names anyone else, or isn’t accepted, it didn’t come from me: move it to the Trash and download Peel again from
github.com/TuguiDragos/Peel
. Before you open the file you downloaded, GitHub’s
gh
tool can check it against its release: once you’re signed in with
gh auth login
,
gh release verify-asset v1.0.1 ~/Downloads/Peel-1.0.1.dmg -R TuguiDragos/Peel
(with your version and where your file is) answers
Verification succeeded! Peel-1.0.1.dmg is present in release v1.0.1
.
Does Peel work on Intel Macs and older versions of macOS?
Peel runs on macOS Tahoe 26 or later, on any Mac that runs it: every Mac with Apple silicon, and the few Intel Macs from 2019 and 2020 that
Apple lists for macOS 26
. It doesn’t run on earlier versions of macOS: each version moves where apps keep their files, so every release is tested by hand before it ships, on macOS 26 and every version since.
How do I uninstall Peel itself?
In Settings > General, choose Remove Peel. Peel removes its helper and its login item, then moves itself, the files that are certainly its own, and its folder in Application Support, all but the Terminal settings zsh and ssh read, to the Trash, and clears its settings. While the helper is installed, this needs an administrator’s account. What you set in Tweaks and on the Terminal page stays as it is. If you installed it with Homebrew, Settings shows the Homebrew command to run instead.
Get Peel.
Free and open source, under the GNU General Public License. Open the disk image and drag Peel into your Applications folder.
macOS Tahoe 26 or later · Apple silicon and the Intel Macs macOS 26 supports
Peel is published in one place only:

Every download on this page leads there. The Homebrew command on this page is the only command that installs Peel, so a site that asks you to paste anything else into Terminal to get Peel is not mine. Any other site, download page, or store offering Peel is not mine, and what it gives you may not be the app I build and sign. Peel is free, so anyone asking you to pay for it is not me.
A lot of software spends its time mapping strings to values. A web server must identify the HTTP method (
GET
,
POST
, …). It must recognize header names. A URL parser must recognize the protocol (
http
,
https
,
ftp
, …). A compiler must recognize keywords.
In C++, the default approach is to put the strings in a
std::unordered_map
.
It works. But notice something: the keys are known when you write the code. They never change. And yet we pay at runtime as if they could change at any time: we hash the whole string, we pick a bucket, we follow a pointer, we compare, maybe we walk a list.
Perfect hashing
A hash function maps keys to slots. When two keys land in the same slot, we have a collision, and we must deal with it. Collisions are what make hash tables complicated and slow.
If you know all of your keys ahead of time, you can construct a hash function designed for your keys, a function that never produces a collision. It is called a perfect hash function. The idea is old: the GNU
gperf
tool has been doing it since 1989. You give it a list of keywords, and it generates C code.
We follow the same design as
gperf
. The slot for a key is computed as follows.
We add the length of the key to a few small values taken from an association table (
asso
) indexed by the characters at a few selected positions. Usually, one or two positions are enough. The table size is a power of two, so the modulo is a single bitwise AND.
Consider the four HTTP methods
GET
,
PUT
,
POST
and
DELETE
. We use only the first character. Set
asso['G'] = 0
,
asso['P'] = 1
and
asso['D'] = 0
. Then
GET
goes in slot 3 + 0 = 3,
PUT
goes in slot 3 + 1 = 4,
POST
goes in slot 4 + 1 = 5 and
DELETE
goes in slot 6 + 0 = 6. No collision.
To look up
PUT
, we compute the slot (4), and we compare
PUT
with the one key stored in slot 4. One hash, one comparison. If you look up
PATCH
, which is not in the set, you land in slot 5 + 1 = 6, you compare with
DELETE
, and you are done: not found. There is no probing, no chain to walk.
How do we find the association values? We sort the characters by how many keys they touch. We then take them one at a time and try 0, 1, 2, … until we find a value that does not cause a collision. We never revise a value once it is set. It is a greedy algorithm with bounded work. The bound matters because we do all of this at compile time, and C++ compilers limit how much work a
constexpr
function may do.
Doing it in C++
With
our library
, you write ordinary C++23. There is no external tool to run.
The map is a compile-time constant. The compiler searches for the perfect hash function when it compiles your code. At runtime, computing the hash can take as few as four instructions: load one byte of the key, load one byte from the association table, add the length, apply a mask.
Comparing strings quickly
Computing the hash is cheap. But we still need to check that the string we are looking up matches the key stored in the slot. And comparing strings can be expensive: the textbook approach is a loop over the bytes with a branch for each byte. You can easily end up with dozens of instructions and several branches, and the branches are hard to predict when the strings vary.
Instead, we treat the key as a vector. Our processors, whether ARM or x64, have 16-byte registers. So we load 16 bytes unconditionally, even if the key is only three bytes long. We then use a shuffle instruction (
tbl
on ARM NEON) to zero the bytes past the end of the key. The stored keys are zero-padded at compile time. A single vector comparison handles the whole key. We go from about forty instructions and eight branches to five instructions and no branch.
But wait: is it safe to read 16 bytes when you only have three? Reading past the end of a buffer is fine as long as you do not cross into another memory page, and pages are at least 4 kilobytes. So we check whether the address is within 16 bytes of the end of its page. If it is, we take a slower path. Otherwise, we do the wide load. We traded several unpredictable branches for a single branch that is almost always taken the same way.
How fast is it?
I ran the benchmarks on an Apple M3 Max with AppleClang 15. We look up the keys in random order and we report the time per lookup. Let us first consider the 20 standard HTTP header names.
We need about 1.3 ns per lookup, or about 5 cycles. The classic
gperf
needs 7.7 ns. Abseil’s
flat_hash_map
, an excellent hash table, needs 10.9 ns. And
std::unordered_map
needs 16.6 ns. We are thirteen times faster than the standard library.
It is not one lucky key set. Here are the results over several sets of keys, from 6 URL protocols to the 100 tickers of the S&P 100.
We stay between 1.2 ns and 2 ns per lookup. We are 3 to 6 times faster than
gperf
, and 7 to 13 times faster than
std::unordered_map
. Notice how
gperf
struggles with the JavaScript reserved words: there we are 17 times faster.
Why is
std::unordered_map
so much slower? The C++ standard essentially requires a chained hash table. A lookup hashes the whole string by calling a function, follows a pointer to a heap-allocated node and walks a list. Our lookup does a few loads and has no function call. The processor can retire over 8.6 instructions per cycle with our code, which is about as good as it gets on this chip, and it almost never mispredicts a branch.
On an Apple M4, with the URL protocols, we exceed one billion lookups per second.
Conclusion
If your keys are known at compile time, you should not pay for collision handling at runtime. A perfect hash function gets you down to one comparison. With some care, a lookup costs about five cycles. The library is a single header you can drop in your project:

A Ukrainian national was sentenced to 70 months in prison for his role in Nefilim and Hive ransomware attacks targeting hospitals, government entities, and high-revenue businesses worldwide between 2018 and 2021.
The sentence
follows the extradition
of 35-year-old Artem Aleksandrovych Stryzhak to the United States on April 30, 2025, after authorities arrested him in Spain in June 2024.
"Artem Stryzhak is a prolific cybercriminal who worked with multiple ransomware groups to target U.S. businesses and hospitals,"
said
Brett Leatherman, the FBI's Cyber Branch Operations Director. "These groups disrupted patient care and caused more than $100 million in losses. Today's sentence reflects the seriousness of Stryzhak's crimes and demonstrates the FBI's global reach and extensive network of international partners."
According to court documents, he paid for 20% of all ransom payments collected for access to custom Nefilim ransomware and decryption keys starting in June 2021.
While active as a Nefilim affiliate until October 2021, Stryzhak used the custom-tailored malware to target large corporations in the United States, Canada, and Australia with revenues exceeding $100 million each year. However, one of the Nefilim administrators later encouraged him to focus on large companies that were generating more than $200 million annually.
To pressure victims into paying, the ransomware operation also threatened to leak data stolen during attacks on dark web "Corporate Leaks" websites managed by the Nefilim admins unless victims met the ransom demands.
Nefilim ransom note (BleepingComputer)
Stryzhak also joined Hive ransomware as an early affiliate, breaching and encrypting the systems of seven victims, including a dentist's office, multiple law firms, and a healthcare provider during the COVID-19 pandemic.
In December 2025, Stryzhak
pleaded guilty
and admitted to computer fraud conspiracy charges brought by US prosecutors in connection with ransomware attacks targeting businesses in the United States, Norway, France, Switzerland, Germany, and the Netherlands.
"Disrupting a ransomware group that attacked approximately 1,500 victims worldwide and sentencing a defendant who had targeted healthcare during the COVID-19 pandemic is of significant importance to this office," added US Attorney Gregory W. Kehoe.
"Ransomware attacks like those committed by the defendant wreak enormous havoc — harming victim companies that pay millions in remediation and ransoms, preventing hospitals and other critical facilities from accessing data, and putting sensitive information in the hands of bad actors," US Attorney Joseph Nocella Jr. noted.
The US State Department also
offers up to $11 million
for any details that could lead to the arrest of Ukrainian national Volodymyr Tymoshchuk, one of Stryzhak's alleged accomplices, who is still at large.
Tymoshchuk is on the most-wanted lists of the
European Union
and the
FBI
, and the US Justice Department
charged him in September
for his roles as an administrator for the LockerGoga, MegaCortex, and Nefilim ransomware gangs. He was also allegedly involved in ransomware attacks that caused millions of dollars in damages to hundreds of companies around the world between July 2020 and October 2021.

The Companion (PDF)
Goodhart’s
law
, that any measurable target stops being useful when people start
optimizing for it, very much holds in database benchmarking. That is not
new, of course. Famously,
TPC-D
got retired when
people optimized so much for it that the query runtimes converged
towards zero due to excessive caching.
TPC-H
fixed that by
declaring itself to be an ad-hoc benchmark, and explicitly forbidding
things like exploiting knowledge about the workload or caching results
(and a number of other optimizations).
We now see the same problem with the
ClickBench
benchmark,
heavily accelerated by today’s use of AI code generation. If you tell an
AI to make the queries faster, it will make the queries faster,
regardless of whether this is a generally plausible approach or not. For
example, the pgrust implementation performs group-by aggregations on
string columns purely on the hash value, ignoring the long string
content. That is a great performance boost, of course, and works for
this benchmark, but can produce wrong results. Is it faster? Yes. Is it
a plausible optimization? Probably not. And it does many other things:
For example, ClickBench repeats certain predicates across queries, and
thus pgrust caches the predicate, completely eliminating the query cost
the second time. Or for query Q17, which returns tuples grouped by
userid, it makes use of the fact that a) tuples are roughly clustered by
userid, and b) the query specifies a limit clause without order by. Thus
any userid will do, and it never reads most of the data. A human would
not do these tiny micro-optimizations, because they are unlikely to be
relevant in general use cases, but an AI can of course look at each
query in detail and tune for it.
Part of the problem is, of course, ClickBench itself. The benchmark
is not well specified in what is permitted and what is not, there is no
update stream, the queries are very simple, share predicates, are
underspecified, etc. But the fundamental problem is independent of that
concrete benchmark: The moment we start aggressively optimizing for a
specific benchmark, the benchmark stops being very useful. Historically,
that pressure was reduced a bit by the requirement that systems be
generally useful. That is, they did not just want to perform well in
benchmarks but also to be useful for their customers. That is, of
course, not a concern for vibe-coded execution engines.
It is not clear what to do about it. Our
SQLStorm
proposal tried
to address this by having tens of thousands of queries, which makes
overfitting harder. No human would fine-tune their system to such a huge
workload. But with AI tools we could even investigate ten thousand
queries in detail if needed, so that is not a real defense.
I think that to be meaningful, a benchmark has to a) like TPC-H, be
ad-hoc, and forbid exploiting prior knowledge and any form of
intermediate result caching. If we don’t do that, execution times
converge towards zero. And b) the benchmark has to include some form of
update stream, as otherwise overly aggressive read-only or read-mostly
systems will always outperform systems that offer full transactional
support. And c) the benchmark has to be truly ad-hoc, in the sense that
the systems tested have to be older than the benchmark. One way to fight
Goodhart’s law would be to (automatically) come up with a new benchmark
from time to time, and then measure the systems that existed before the
benchmark. The caching/pre-computation problem still remains, of course,
but at least that would prevent the over-aggressive adjustment to just
one specific benchmark.
Interestingly, the machine learning community has struggled with
exactly the same problem for years, and we should probably borrow some
of their ideas. Kaggle competitions, for example, rank submissions on a
hidden test set that participants never see, which makes overfitting on
the public data pointless. Similarly, benchmarks like
LiveBench
regularly release new
questions to make sure that models cannot have seen them during
training. For database benchmarking that could mean keeping the actual
benchmark queries secret and only publishing a representative sample for
development, or, even better, generating a fresh workload for every
evaluation round. SQLStorm already uses generated queries, so producing
a new query set from time to time would be fairly easy. We would
probably want a more generic approach (higher variety in schemas, update
streams, transactions, etc.), but that seems to be a direction that
would help keep benchmarks meaningful.
It is Friday after all, so I’ll offer this little glimpse as an example from what I do at work…
A while ago, I was working for a customer (who shall remain unnamed here, but let’s call it
Intel
) doing system simulation software. I worked on this project for a year or so. I ran full x86 systems completely simulated. During that time I was chasing some nasty bugs in the simulated usb-disk device that caused my Windows boot to end up in a blue screen.
I struggled to figure out why Windows 7 would write 0xABADBABE to EHCI register index 0x1C – which is a reserved register – during boot some 10 milliseconds before the blue screen appears, and I was convinced that it was due to a flaw in the EHCI simulation code and thus was the first indication of the failure. If I didn’t have any simulated usb-disk inserted that write wouldn’t occur, and similarly that write would occur even if I inserted the usb-disk much later – like even after Windows 7 had started and I was passed the login screen.
An interesting exercise is to grep for this (little-endian so twist it around!) 32 bit pattern in a freshly installed windows 7 file system – I found it on no less than 16 places in a 20GB file system. This
bgrep
utility was handy for this.
To properly disassemble that code, I hacked up a quick
bcut
tool so that I could cut out a suitable piece of the 20GB file to pass to objdump, as objdump very inconveniently does
not
offer an option to skip an arbitrary amount from the beginning of a file! Also, as it is not really possible to easily tell on which byte x86 code starts at, I had to be able to fine-adjust the beginning of the cut so that objdump would show correctly (this is x86-64):
But then, reading that code never gave me enough clues to figure out why the offending MOV is made.
Thanks to a friend with a good eye and useful resources, I finally learned that Windows does this write on purpose to offer some kind of break-point for a debugger. It always does this (assuming a USB device or something is attached)!
A red herring as far as I’m concerned. Nothing to bother about, just MOV on! I simply made the simulation accept this.
Oh. You want to know what happened to the blue screen? It had nothing at all to do with the bad babe constant, but turned out to be because the ehci driver finds out that some USB data structs the controller fills in get pointers that point to memory outside of the area the driver has mapped for this purpose. In other words it was a really hard to track down bug in the simulated device.
I tested eight popular SVG sanitizers and bypassed six of them. In this post, I'll show you how a response header can run JavaScript in Firefox even when the response body is completely harmless XML. I'll also show you how to get Safari to import a GIF as SVG and execute JavaScript from it.
Hacking SVG sanitizers
The targets
SVG is an image format that can contain scripts, event handlers, links, animations and even embedded HTML, so applications that accept SVG uploads usually run them through a sanitizer first. To see how well those sanitizers hold up, I tested the most popular SVG libraries according to ChatGPT:
This library has so many bypasses that I'll only cover the interesting ones.
My first finding was that you don't need
<foreignObject>
to get HTML into an SVG. Switch the XML namespace on a single element to XHTML and the browser renders it as HTML directly inside the SVG. A
<frame>
with a JavaScript URL is all it takes:
The library could also be bypassed with a plain old
<foreignObject>
. It renders the SVG, which converts the element name to its camel-case form, foreignObject. It then hunts for the element with
querySelectorAll('foreignobject')
, which finds nothing, so the payload goes straight through:
Now things get more interesting. This is a pretty epic technique: you can get JavaScript execution from an XSLT stylesheet without needing a separate file. I was desperate to blog this one, because unfortunately the feature is deprecated and due for removal November 2026.
The trick is to point an xml-stylesheet processing instruction at a data URL. Base64 is the most elegant way to encode the stylesheet, but URL encoding works too:
It matches the root of the document and outputs an HTML page containing a script that alerts document.domain, proving the code runs in the document's origin rather than a null origin. Put it all together and you get this:
In the back of my mind was a trick
Paulos Yibelo
once told me about: Firefox lets you load external CSS files using a Link response header. I figured out that data URLs work there too, which got me thinking: if it works for CSS, could it work for XSLT too? You're damn right it can.
First, I needed a version of the stylesheet that fits in a URL. This one has two layers. The outer stylesheet is URL encoded into a data URL. Inside it, XSLT's
document()
function loads a second data URL, URL encoded again, containing an XHTML
<img>
with an
onerror
handler. The stylesheet copies that into a
<foreignObject>
, where it fires.
To end this piece of research, here's another epic behaviour, this time in Safari. Firefox and Safari both let you use the <use> element to reference same-origin files, but Safari goes a step further: it lets you import image files as SVG!
Alas, you can't make a true SVG/image polyglot because SVG is a little too strict. However, if you can upload a GIF that contains the payload, it won't render when you open it in the browser, but it can still be imported with a
<use>
element!
That's all it takes to bypass all three libraries:
I hope you enjoyed this post. I also exploited two popular applications that I can't name yet, but I'll update the post once I can. Both DOMPurify and darylldoyle/svg-sanitizer held up against everything in this post, which is quite impressive.
‘Emotional intimacy’ from AI chatbots would be banned under Australia’s digital duty of care laws
Guardian

The federal government wants to ban AI chatbots which seek to create “emotional intimacy” after prime minister
Anthony Albanese
raised the alarm in a heartfelt speech about children treating these agents as their “best friend”.
But Labor is coming under increasing pressure to empower the telecommunications ombudsman to become a watchdog for social media and AI to give Australians an external complaints mechanism and allow the “naming and shaming” of big tech.
The digital duty of care bill passed the House of Representatives on Wednesday and will be debated by the Senate in coming weeks. The government hopes to pass the bill by the end of 2026, but its pathway through the upper house remains unclear. The Greens support the bill, while
the Coalition has said it will not vote for it
, though Labor still appears keen to win the opposition’s support and
remains open to amendments
.
The planned framework would apply new online safety standards to social media, games, apps and chatbots. Labor said it would place “an overarching obligation” on tech platforms “to provide a safe online environment for all Australians” and replace a range of existing online codes and standards with a broader duty-of-care requirement to protect users from certain “harmful” content. It would also require social media platforms to offer an “opt-out” feature for its algorithm and suggested content.
The communications minister, Anika Wells, has suggested content that that promotes misogyny, terrorism, suicide, self-harm and eating disorders
would be captured by the laws
. On Wednesday, the government accepted amendments from crossbencher Kate Chaney which would add certain AI chatbot activity to the list of harms, requiring platforms to ban “material or conduct that simulates emotional intimacy and encourages or fosters a child’s dependence on it in place of human relationships”.
In an emotional address on Tuesday night, where he again implored the Coalition to consider voting for the bill, Albanese said: “the stories we hear about people identifying a chatbot, a non person as their best friend, should be a huge wake up call for every member of this Parliament to be prepared to act.”

The opposition voted against the bill in the House, alongside One Nation. Political opponents have
accused Labor of an “Orwellian” system of “censorship”
and of seeking to influence conversations online – claims Wells strongly denied.
“If they really care, the test is simple here, they should bring an amendment, not a slogan to ‘kill the bill’,” Wells told ABC radio on Wednesday.
Another Chaney amendment accepted by Labor would require the algorithm opt-out features to be “accessible, easy to use” and “prominently available” on platforms,amid concerns that social media giants may offer only small or hard-to-find features.
The bill now moves to the Senate, where the Greens have set up an inquiry to probe the laws due to report back in late November. Senator Sarah Hanson-Young backed a digital duty of care, calling for the government’s legislation to be strengthened The Greens want Australians to have the right to pursue private legal action against platforms and for penalties to be increased.
“Australians also need an external complaints pathway, free from the profit-driven whims of ‘big tech’s’ content moderation,” she said.
Independent MP Sophie Scamps had proposed changes to the bill to expand the remit of the telecommunications industry ombudsman. She said such a watchdog – which does not currently exist for big tech – would allow ordinary social media users to seek remedies to their accounts being hacked or inaccessible, including compensation, and investigate broader issues to name and shame companies behaving badly.
Labor did not accept this amendment in the lower house and Wells declined to voice support for such an idea, but the Greens will push for such a reform in their Senate negotiations.
Cynthia Gebert, the telecommunications industry ombudsman, said her office would be well placed to carry out such a role for big tech. She said such roles were funded by the industries they regulate and that expanding its remit could be financed by big tech.
“There are some real strengths in the DDOC [digital duty of care] because it’s putting the onus on platforms to make things safe … but I think the area that needs to be strengthened is giving people somewhere to go if they can’t get their complaints resolved with the platform,” Gebert told Guardian Australia.
“It risks leaving Australians in the safe place they are now, where they get automated responses or escalation procedures that don’t go anywhere.”
Gebert said the government should make it mandatory for big tech to be part of an ombudsman scheme, saying it would “hold industry to account and drive system improvement”.
“[The telecommunications industry ombudsman] can help with your Telstra account, but we can’t help with your Gmail account. Consumers come to us sometimes and ask, ‘why this, not that?’,” she said.
“We want to help but don’t have the powers to do so now.”
What a
week
,
huh? High fives all around—October is
"Cybersecurity Awareness Month", and I think we've all
done a stellar job. If both the
New
York Times
and
NPR
report on one of the at least four or five
concurrent
fires
I'm fighting, then I think we can say that
yeah, people are aware of cybersecurity. Mission
accomplished, so... could we maybe turn it down a bit?
The current situation is not sustainable: 0-days are
dropping left and right, pre-notifications and
embargoes are
broken
for marketing purposes
, AI companies compete first
on who commits the most crimes and then pretend to
sell you protection in the form of a DoS on the Open
Source community. "
Nice project you got there. Be
a shame if somebody dropped an 0-day on
it."
1
Companies are not staffed for this, and no matter what
the industry wants to tell you, you can't AI your way
out of this. Vulnerability discovery has
fundamentally changed, disclosure processes are
effectively broken
, and patch management
has been a losing proposition for years now. Severe
vulnerabilities are identified and disclosed at a pace
that defenders are unable to keep up with.
This is because it still takes significant resources
to accurately assess the feasibility of a given
vulnerability within your environment; it takes time
to discover your attack surface relevant to the given
attack vector, and it takes even more time to deploy a
fix. As I've
said
before
, development of the fix is not the
bottleneck. Let me illustrate with examples from the
last couple of days:
Initially disclosed as a "KVM escape", this
vulnerability
also
applies to other
virtualization as well as containers, although that
angle hasn't really gotten much attention. You now
need to assess which possible mitigations might be in
place across your fleet of systems, then determine
whether you can
livepatch
your kernels with the custom patches you pull from
upstream or if you want to wait for your upstream OS
provider to deliver a new kernel
2
and then all you
have to do is reboot a few thousand systems.
How does AI help you here? Maybe you spend a few
thousand dollars on tokens to use the most advanced
cyber cyber models to develop your own exploit, but in
the end, that doesn't really tell you anything you
didn't already know, and your defensive position and
tasks at hand remain the same.
This one's fun, isn't it? Sure, browsers were all set
quickly, but guess what, there's a few other
things that might use TLS in your environment.
Like...
everything
. So again, having the
fix is not the bottleneck. Waiting for upstream
packages to release an update only blocks you if you
actually know that you need to pull in that update.
Oh, you have a detailed package inventory or, dare I
say it, SBOMs? That's really nice. Do show me where
that lists the various
vendored
or hard-coded CA trust bundles
. Yeah, I didn't
think so.
3
(At least this incident was not AI generated,
detected, or triggered. Just one of your wholesome,
classical,
a-human-going-"huh"
kind of discoveries. It's almost reassuring that we
still get these, too.)
The PHP vulnerability that supposedly affects "over
70% of websites" (a widely quoted, but never
attributed statistic) was disclosed under embargo to
several organizations. If you were part of this inner
circle, then this should have reduced your panic-mode
somewhat, buying you at least
some
time to
deploy protections for your customers and do the
tedious work of sifting through your inventory and,
again, identify the attack surface, affected systems,
possible local mitigations, etc. etc. The usual.
Unless the embargo is broken. Then you get to
scramble again. And you need to keep up to date with
all the rapidly published (and increasingly verbosely
AI polluted) breathless blog posts driven by cyber
security vendors' marketing teams eager to beat each
other as the first to detect
4
, first to exploit, first
to brag, all of which adds to the distraction.
And of course you
still
need to do the actual
work of determining the accuracy of the various
exploits floating around the internet, some put
together by people with a clue and many, many slopped
together by those lacking a full understanding of the
bug
5
. (More on that below.)
And then, by the time
Thursday
rolls around, people start
to see a
NodeJS
security advisory
, which includes as the third
"high" severity vulnerability an issue with the
"Node.js Brotli decoder". Alright, attack surface
enumeration, software inventory check, start to deploy
updated packages,... the usual.
Except, of course, once you take a closer look, it
begins to
dawn
on you
that this goes well beyond just
Node.js
6
. And so once again,
having the
upstream
fix
available is absolutely not your bottleneck,
because you still need to find the plethora of
frankenstances of brotli across
all
of your
stacks first.
Of course at that point in time OpenAI
starts
to go
"Us! It was us! We found it!" even though
the issue
was
fixed back in February
and Mozilla
noted
the critical security impact
as far back as April.
It seems there's no vulnerability, no compromise, no
cyber crime AI companies are not willing to claim as
their credit.
(More) Winter is Coming
All of this was going on over the course of one week,
and doesn't even account for the previous set of
weekly Linux local privilege escalation
vulnerabilities
7
. And no doubt there will
be more such disclosures—many more.
AI companies are incentivized to continue the
onslaught, with the most benevolent interpretation of
mass disclosures of findings being a canonical example
of "
verschlimmbessern
",
with less friendly interpretations observing that it's
profitable for a company to create the disease for
which they're selling you to treatment (and never the
cure). They've got a new toy, it's a hammer, and by
golly they're gonna swing it.
Millions of dollars have been spent on identifying
vulnerabilities using so-called "frontier AI models",
and we know that adversaries are feeding, e.g., the
Linux kernel commit messages into their models to
analyze them for exploitable vulnerabilities on the
fly. Today, vulnerabilities are found independently
by multiple parties on a regular basis, so you already
have to assume that a disclosure embargo
only contains
the
massive
exploitation
by opportunistic adversaries at best.
At the same time, I'm observing a worrying trend on
the defensive side of cyber security, which mirrors
the same de-skilling trend across the industry: AI
generated vulnerability reports are often much, much
too verbose to be digested easily by human readers.
They drown you in details, overwhelm your attention
with unnecessary information. Because defenders don't
fully understand the vulnerabilities described here,
they tend to believe the generally exaggerated
severity claims, and feed the full report into
their
AI to reproduce or generate a proof of
concept.
Several thousand tokens later, you end up with a
binary handed to you by a meat-proxy that's supposed
to trigger the vulnerability, but nobody actually
understands why it works. Which, more often than not,
it actually
doesn't
, because your environment
is different, your AI was missing context the
meat-proxy didn't (know to) provide, because the code
base differs from upstream, or who knows what else.
When you ask for clear instructions on how to run the
exploit, what pre-conditions need to be met, and how
it works—you know, the kind of one-pager that
offensive engineers used to be able to
produce—you get back, you guessed it, an
AI-vomited 7,000 word
README.md
.
8
Incident Fog
Fighting one fire at a time is taxing enough. Each
one of the above examples would have been a
once-a-year incident not too long ago. Having
multiple such incidents at the same time is burning
out all your incident response staff, your engineers,
your comms and legal teams.
(And it always
is
more or less the same set
of people driving each incident. I have not seen
organizations properly staffed and not relying on the
same set of ghostbusters—the heroes and company-elders with the
required tribal knowledge to make up for the gaps in
your software inventory, attack surface enumeration,
and documentation, because who else are you gonna
call?)
Context switching between each of these incidents
means you can't focus on any one of them, making you
more likely to miss important information, to fall for
sensationalistic headlines, to succumb to pressure and
to rush fixes you don't understand for vulnerabilities
that might not apply in your environment. Which, in
turn, makes more people more susceptible to the
appealing lure of quick and confident answers from the bot, and
subject-matter non-experts start to paste their prompt
results into incident response channels.
This is not sutainable.
How it gets better
Oh, lol, sorry, I mislead you. When you ramble and
rant, you're supposed to end on an upbeat note,
provide a solution
9
, proffer suggestions on how we can
all roll up our sleeves and work together and solve
the problem. Alas, I have no idea.
Ah, but surely all of this is just
temporary
,
right? AI will find all the vulns, we slog through
this dark winter of disclosure chaos, and then come
out in a world where all software vulnerabilities have
been found and fixed.
If you're able to believe that, I envy you. I don't
see it happening. If you try to tell me that software
developers should just use AI to generate patches,
remember that
over
50% of the time
, AI either doesn't fix the issue,
introduces a new vulnerability, or changes the
application's behavior in the process. Reducing our
own understanding of complex software while
simultaneously
producing
more and more code
is a recipe for
more
vulnerabilities, not fewer. And, at the risk of
sounding like a broken record,
getting the
vulnerability fixed is not the bottleneck
.
Even if the current status were temporary—for
how long? A year? Two? And what are we supposed to
do in the meantime? Hiring more infosec staff isn't
likely to happen
in
this economy
. Investing into overhauling your
entire infrastructure such that you can at least
pull in and deploy updates automatically and reboot your
fleet and do all that
safely
is equally
unlikely: companies have gotten away with
not
doing that for decades, and who wants to be the VP or
executive who shifts funding away from "moar code moar
faster"? Not to mention that such a project would
take several years as well.
The last option left is to simply accept the status
quo. There will be more vulnerabilities, including
RCEs, and you won't be able to keep up with them.
Your only option is to limit the blast radius.
Assume compromise, detect exploitation, limit
exposure, lateral movement, privilege escalation, etc.
If that sounds like an old hat, well, yes, that's what
sane infosec practitioners have been asking for
funding for for decades. (We used to call it "Zero
Trust", before that became an empty marketing term.)
But that funding instead goes to the next singing
and dancing, AI-based vulnerability management SIEM
dashboardmajing, which will only miss 40% of your
infrastructure and assets. Hooray!
Well, good night and good luck, indeed.

to restrict their malware. I'd also like to hold

The Bolsonaro Family Playbook: Lose, Cry Fraud, and Run to Trump’s America
Intercept
theintercept.com
2026-10-27 23:11:52
Brazil’s Supreme court tried to strip Flávio Bolsonaro's passport, but the Trump administration granted him a visa, according to reports.
The post The Bolsonaro Family Playbook: Lose, Cry Fraud, and Run to Trump’s America appeared first on The Intercept....
Brazilian right-wing presidential candidate Flávio Bolsonaro holds a picture of his father, convicted former President Jair Bolsonaro, during a motorcade with supporters in Goiania, Brazil, on Sept. 27, 2026.

Andrew Fishman is an investigative journalist based in Rio de Janeiro and the president of The Intercept Brasil.
“I never thought
about leaving the country,” Flávio Bolsonaro, a Brazilian senator and son of the deposed, disgraced leader,
told
his 16 million Instagram followers on Monday. It was the day after he lost the presidential election to President Luiz Inácio Lula da Silva by a margin of more than 4 million votes.
Flávio promised to stay in Brazil to “organize the opposition” during Lula’s next term.
“I’m the last obstacle to the Workers’ Party’s plan to destroy the country,” Flávio warned, referring to the party of Lula, who defeated his father four years earlier.
A few hours later, he left his mansion in Brasilia and sought asylum in the U.S. The Trump State Department
told
the Associated Press that it will grant him and his family visas.
The affinities become obvious when you watch Bolsonaro’s failsons end up in Trump’s America.
“I didn’t take sides, but it looked like another rigged election,” President Donald Trump
told
reporters on Monday, echoing Flávio’s election night talking points without providing any credible evidence that casts doubt on Lula’s come-from-behind victory — even as Flávio’s own party put out a
statement
acknowledging the results later that day.
It is no coincidence that the Trumps and the Bolsonaros are so fond of each other. Their modus operandi is nearly identical.
Both wrap themselves in the rhetoric of patriotism and moral righteousness, while treating their political offices as personal get-rich-quick schemes. And, when their lies finally catch up with them, you can be sure that they will jump ship to save themselves first and abandon their followers.
The affinities become obvious when you watch Bolsonaro, his failsons, and co-conspirators all end up in Trump’s America, where Flávio is about to join his brother, and in the denialism and violence that follow their failures.
Coups and Flight Risks
Flávio Bolsonaro’s election denial and hasty escape are his version of Trump’s infamous January 6 speech: Rile up the troops to do your dirty work and get the hell out of the way.
It’s not the first time a Bolsonaro ran this playbook. After Jair Bolsonaro became the first modern Brazilian president to lose a reelection bid, he refused to attend the January 2023 inauguration ceremony. Instead, he also fled to the U.S.,
staying
in a Minions-themed children’s bedroom in the Orlando, Florida, home of retired UFC fighter José Aldo.
A week later, on January 8, the ex-president’s allies laid siege to the capital, Brasília, vandalizing Congress, the presidential palace and the Supreme Court, as foot soldiers in a larger coup plot to overthrow the Lula government. Nearly four decades of Brazilian democracy was only spared when key military leaders blinked before they could finish the job.
Jair Bolsonaro eventually returned to Brazil and was
sentenced
to 27 years in prison for leading the plot, which included a plan to assassinate Lula, Vice President Geraldo Alckmin, and Supreme Court Justice Alexandre de Moraes. Allies, including top military brass, were also convicted. Jair remains under house arrest — widely thought to be pinning his hopes for freedom on a Flávio presidency that wasn’t to be.
Flávio, however, will not be lonely in the States. His brother, former Brazilian Congress member Eduardo Bolsonaro, just
received
green cards for his family and is living in a $1.2 million McMansion in Southlake, Texas, in the Dallas-Fort Worth area, as we
revealed
in The Intercept Brasil earlier this year. Eduardo, who is a regular on the Trumpworld circuit, was sentenced in absentia to four years and two months in prison for lobbying the U.S. government to interfere in his father’s trial.
Flávio, too, seems poised to receive news of his own prison sentence while sitting on a couch in a Texas suburb. In May, our reporting at The Intercept Brasil put the first nail in the coffin of his presidential campaign when we
published
chat logs and audio recordings of the senator negotiating $24 million — and being wired $10 million — from disgraced billionaire banker Daniel Vorcaro, who is a sort of Brazilian cross between Charles Ponzi and Jeffrey Epstein.
The payments, wired to a U.S. account, were supposedly meant to finance “Dark Horse,” a biopic about Jair Bolsonaro starring Jim Caviezel. Brazilian Federal Police, though, have already
poked holes
in Flávio’s story as they investigate whether the money was actually used to bankroll Eduardo’s treasonous lobbying of the Trump administration to sanction Brazil and help his brother’s electoral chances.
Flávio is also being investigated for his alleged ties to a billion-dollar money-laundering scheme through an online betting company run by Willer Tomaz. The two are not only close friends but also business partners. Flávio even had unfettered access to one of Tomaz’s offshore bank accounts. You will not be surprised to learn that Tomaz
left
Brazil in August and is now living in Miami.
Police argued that, after losing the election, Flávio would pose a flight risk,
especially
in light of his closest associates’ recent actions. They asked the Brazilian Supreme Court to order Flávio to turn over his passport, which is permitted under Brazilian law. A top justice granted the request and, when the deadline passed, canceled the senator’s travel documents.
Index v5 features 2 new benchmarks and 3 upgrades. For the first time, the majority of the Index is built on private datasets
The Artificial Analysis Intelligence Index is our composite measure of model capabilities across tasks reflecting real-world usage today. v5 is our biggest upgrade since v4 launched in January. With v5, 60% of the Index is now based on evaluations with private test sets or held-out answers.
Alongside Intelligence Index v5, we’re launching the Artificial Analysis Progress Index v1, which tracks model capability over time on one continuous scale.
New to the Intelligence Index:
➤ FrontierCode 2.0:
Cognition's newly-launched private benchmark of real-world coding tasks, graded on whether a repository maintainer would merge the agent's change
➤ Terminal-Bench-Science:
70 agentic scientific research tasks, run in a terminal environment
Upgraded:
➤ HLE-Diamond (replacing Humanity's Last Exam):
a refined 1,000-question version of Humanity's Last Exam, split evenly between reasoning and knowledge questions
➤ AA-Omniscience v1.1:
an updated dataset with saturated and public set questions removed, new questions added, and ambiguous or erroneous questions revised
➤ CritPt v2:
a private, 40-question hard subset of CritPt v2, revised by the CritPt authors and run with a code-execution tool
Staying in the Index:
AA-Briefcase, AutomationBench-AA, GDP.pdf and Terminal-Bench 4.0
Removed from the Index:
GDPval-AA v2.1, SciCode, and AA-LCR v1.1
Intelligence Index v5 weights:
➤ Knowledge Work (25%):

Key results:
➤ Claude Opus 5.5 (max) leads at 58, ahead of GPT-6 Astra (max, 57) and GPT-6.1 Sol (max, 55):
Anthropic and OpenAI hold the top five models. Gemini 4 Argon (high) is next at 50
➤ The open weights gap widens from 3 points to 12:
Kimi K3.1 Pro (weights not yet released) is the top open weights model at 46. Among released weights, DeepSeek V4.1 Flash 1017 (max) and GLM-5.3 (max) lead at 32 - 26 points behind the leader and below Claude Haiku 5.5 (max, 36)
➤ Cost per task varies by more than 13x among the leading models:
of the 10 highest-scoring models shown, GPT-6.1 Terra (max) is the cheapest at $0.96 per Intelligence Index task and Claude Fable 5.1 (max) the most expensive at $13.04
FrontierCode 2.0
is the latest update of Cognition's private coding benchmark. Launched earlier today, it comprises 132 tasks in real open-source repositories, graded on whether a maintainer would merge the agent's change. An attempt that fails any blocking check scores 0, and the tasks stay private to avoid contamination. We run every task three times in Stirrup, our agentic harness.
Claude Opus 5.5 (max) leads at 46%, followed by GPT-6 Astra (max), GPT-6.1 Terra (max) and Claude Sonnet 5.5 (max), all at 42%. DeepSeek V4.1 Flash 1017 (max) is the highest-scoring open weights model at 28%, 18 points behind the leader.
Terminal-Bench-Science
tests whether agents can carry out scientific research workflows in a terminal. Experts curate and review each task, and a task passes only if every one of its tests passes.
GPT-6 Astra (max) leads at 63%, followed by Claude Opus 5.5 (max) at 59% and GPT-6.1 Sol (max) at 58%. Scores drop off sharply below the leaders: the best open weights model, Kimi K3.1 Pro (weights not yet released), scores 34%, and Claude Haiku 5.5 (max) scores 20%. The best open weights model with released weights, DeepSeek V4.1 Flash 1017 (max), scores 13%, and most open weights models we benchmarked score under 10%.
HLE-Diamond
replaces Humanity's Last Exam in the Index. It is the refined 1,000-question version of Humanity's Last Exam from the Center for AI Safety (CAIS) and Scale AI, split evenly between reasoning and knowledge. Claude Opus 5.5 (max) leads at 68%, followed by GPT-6 Astra (max) at 64% and Claude Fable 5.1 (max) at 60%.
Knowledge questions are harder than reasoning questions for the leading models: Claude Opus 5.5 (max) and GPT-6 Astra (max) both score 78% on reasoning, compared with 58% and 50% on knowledge.
AA-Omniscience v1.1
is a cleaned version of our knowledge and hallucination benchmark, with saturated and public set questions removed, new questions added, and ambiguous or erroneous questions revised. Scores are mostly aligned with v1, with models scoring on average 2 points lower on the AA-Omniscience v1.1 Index (median 0.6). We’ve also released a new public subset on Hugging Face, AA-Omniscience-Public-v1.1, recalibrated to ensure accuracy, hallucination rate, and overall performance are consistent between the public and private sets.
The Index scores
CritPt v2
on a private 40-question hard subset: the 70 research-level physics questions, minus the 30 that seven frontier models solved in all five attempts at launch. Models work in an offline Python sandbox in Stirrup, our agentic harness.
GPT-6 Astra leads at 72% on high effort, followed by GPT-6.1 Sol at 69% on max effort. Claude Opus 5.5 (max), the top model in the Index overall, scores 61%. Kimi K3.1 Pro (weights not yet released) is the highest-scoring open weights model at 45%.
v5 leaves significant room for progress across all nine evaluations, and no single model leads them all.
Of the models we measured, Claude Opus 5.5 leads three, and five other models lead the remaining six:
➤ Claude Opus 5.5:
FrontierCode 2.0 (46%), HLE-Diamond (68%) and AA-Omniscience v1.1 (48)
➤ GPT-6 Astra:
Terminal-Bench-Science (63%) and CritPt v2 hard subset (72%)
➤ Claude Sonnet 5.5:
AA-Briefcase (1812 Elo)
➤ Kimi K3.1 Pro:
Terminal-Bench 4.0 (67%)
➤ Gemini 4 Argon:
AutomationBench-AA (78%)
➤ Muse Wonder Full:
GDP.pdf (33% all-pass)
Open weights models fall further behind in v5.
The best, Kimi K3.1 Pro (weights not yet released), scores 46, 12 points behind the leader, compared with a 3-point gap in v4.3. Of models with released weights, DeepSeek V4.1 Flash 1017 (max) and GLM-5.3 (max) score highest at 32, and Claude Haiku 5.5 (max) outscores all of them.
The gap is widest on HLE-Diamond and Terminal-Bench-Science, where Kimi K3.1 Pro scores 37% and 34%, compared with 68% for Claude Opus 5.5 (max) and 63% for GPT-6 Astra (max).
Cost varies widely among the leading models.
Claude Opus 5.5 (max) costs $10.04 per Intelligence Index task, GPT-6 Astra (max) $6.24 and GPT-6.1 Sol (max) $1.27. GPT-6.1 Sol (max) scores within 4 points of Claude Opus 5.5 (max) at about an eighth of the cost per task.
Effort settings matter more in v5 than in v4.3.
Claude Opus 5.5 scores 35 at low effort and 58 at max, at 10x the cost per Intelligence Index task ($0.98 vs $10.04). Claude Sonnet 5.5 spans 29 points from low to max, up from 20 in v4.3, and GPT-6.1 Sol's spread doubles from 10 to 20 points.
v5 tasks demand substantially more work from models.
Every model we measured generates more output tokens per Intelligence Index task than in v4.3, with the median rising by two thirds, from 35k to 59k.
➤ Agentic evaluations account for most token use:
Terminal-Bench-Science, Terminal-Bench 4.0, AA-Briefcase and FrontierCode 2.0 make up 55% of the Index weight but a median ~90% of output tokens
➤ Terminal-Bench-Science is the most token-intensive:
it accounts for about a third of output Tokens per Task on its own
Alongside v5, we're launching the Artificial Analysis Progress Index v1.
It places language models released since November 2022 on one capability scale, across a wide span of benchmarks.
Use the Progress Index to compare how underlying capability has changed over time, including between models released years apart. To compare models for current use cases and understand the present frontier, use the Intelligence Index, which remains our primary measure of current model intelligence.
Thank you to Epoch AI and Anthropic - we built on learnings from the Epoch Capabilities Index in designing the Progress Index.
Thank you to Cognition, Steven Dillmann and the Terminal-Bench team, the Center for AI Safety, Scale AI, and Minhui Zhu, Minyang Tian, Hao Peng and the CritPt team for the benchmarks behind this update.
Abstract:
Early AI programs were often also theories of how people think, and programs that wrote programs were, in part, theories of how people program. Here we report on the reanimation of two such programs that offer two seemingly different theories of programming and were developed for quite different purposes. The first, Herbert Simon's Heuristic Compiler (1961), was an experimental model of programming as problem-solving, applying the means-ends analysis methods of the General Problem Solver to investigate the nature of the programming task. The second, KBEmacs (1984), was a working prototype of an intelligent programming assistant developed by MIT's Programmer's Apprentice project, built on the view that expert programmers recognize and combine familiar patterns, or "cliches." It let a programmer build up programs by combining cliches through a stylized English command language. We approach both through the methodology of Executable Archaeology, the study of historical computational systems by running their original code, a process we call "reanimation." Our reanimation of the Heuristic Compiler reproduces the compiled code appearing in Simon's 1963 paper, and our reanimation of KBEmacs reproduces the SQRT sequence of its December 1984 self-test. Examined side by side, the two theories turn out to have much in common: the Heuristic Compiler also works by adapting existing routines, and Simon later argued that search alone requires a large body of programming knowledge. To highlight the reflexivity of this project, we deliberately used a modern AI-assisted programming tool, Anthropic's Claude Code (Opus 5.5), to carry out much of the detailed reanimation work, building on a significant base of existing software. The explicit, executable theories of programming that both systems embodied are largely absent from today's far more capable AI coding assistants.

A programmer can point at any line of code and see who wrote it, when, and what the file looked like on any past day. A lawyer reading a federal statute usually cannot, at least not without an afternoon in the notes at the foot of the section. But why shouldn't they have the same, convenient system of record? It is especially relevant given that so much first-pass legal research now runs through language models, which are often unable to utilise the proper lineage of a law, handcuffing its ability to offer interpretation.
The US code
Outside the titles Congress has enacted as positive law, the code is only prima facie evidence of the law, and the Statutes at Large govern where the two differ.
[
1
]
The Office of the Law Revision Counsel publishes it as a series of release points, each current through a named public law, and keeps reorganising it; a bill to enact title 41 as positive law was introduced in September 2025.
[
2
]
Which public law wrote a sentence is recorded in amendment notes, in prose. When a change took effect is often in a separate effective-date note, and where Congress said nothing the default rule is that a law takes effect on the day it is enacted.
[
3
]
The definition of a small business debtor in 11 USC § 1182(1) shows how far apart those answers can be. It was created in 2019 with the existing small business debt limit.
[
4
]
The CARES Act raised the limit to $7.5 million in March 2020 as a temporary measure, later extended to March 2022.
[
5
]
,
[
6
]
That increase lapsed on 27 March 2022, and on 21 June 2022 Congress restored it for two more years, for cases commenced on or after 27 March 2020 and still pending, which reached back over the gap.
[
7
]
The higher limit expired again in June 2024, and after the triennial adjustment in April 2025 it stands at $3,424,000.
[
8
]
,
[
9
]
For a case filed in May 2022, the release point printed at the time gives the lower limit, and only a later Act changes the answer. A history that is useful to a lawyer has to carry the text, the date each change took force, and the scope of any law that reaches back.
A study from the Technical University of Munich this year found two failures in models answering questions on German statutes: they apply rules that were superseded after their training cutoff, and they prefer the newer provision even when an older one governs the facts. One model answered 24% of post-cutoff questions correctly on its own and 87% when the relevant statutory text was retrieved for it, and the authors conclude that temporal validity has to be treated as a hard constraint.
[
10
]
Other recent work trains search agents to respect the date a question is about, with large gains in consistency.
[
11
]
Asking a model to produce the old text does not solve this. When the same Munich group had a model apply German amending laws to earlier versions, the output looked 93–99% similar to the official text, but only half of single amendments and a fifth of chains of amendments matched exactly, and experts found legally significant errors in the near misses.
[
12
]
The history has to be checkable.
For each pair of release points from 2017 onward, we took the public laws enacted in between, carried out their amending instructions on the older text in date order, and compared the result with the newer version. Of 365 changes across the nine titles, 361 reproduced the next release point exactly. The other four are shown with a label saying how far they could be confirmed. Each change then carries the law and the date it took effect: 261 took effect on enactment by default, 72 by an effective-date note and 29 by a date in the amendment itself. One depends on an agency determination that may never come, and we leave it out of the text rather than guess.
With that record, the reader can answer the questions lawyers ask. You pick a date and get the text in force on it, with the words that read differently today marked. Each phrase is coloured by the Act that wrote it. A change to a defined term lists every other provision that uses it, and you can follow a section to see what has changed since your last visit.
Limits
It does not yet show a later law’s reach back on the earlier dates it covers, so for a case filed in the 2022 gap it shows the lower limit without warning that the June 2022 Act changed the answer.
Effective-date notes are read by pattern, and unusual wording falls back to the date of enactment.
Each change links to the law’s own words, and for anything that matters the original should be read.
We're also still thinking about the right form factor this should take.

Follow up on: https://lobste.rs/s/73ozwc/lobsters_nyc_meetup_on_28th_october
Under "Alex". Feel free to come a bit later or earlier. I'll write here updating if we move etc.
Walker's is by the Canal St. metro stop: https://maps.app.goo.gl/mdEgSkBV2H1NSXAdA and has food and drinks....
Moxnox is an NT-like, POSIX-compatible hobby OS which runs on btrfs and is
capable of self-hosting. That means:
Its design, such as the choice of syscalls, is modelled after that of Windows
NT...
...yet at the same time, it should be capable of running software written for
Unix-like systems, provided that they have been recompiled for it, and comes
with a full GNU base system
It is mature enough that you can build Moxnox on Moxnox
And it runs on everybody's favourite Linux filesystem
Version 1.0 is around 130,000 lines of C++, and runs on amd64 and aarch64.
The btrfs code works for basic purposes, but has not been battle-hardened.
Please don't try to mount anything but throwaway filesystems.
efibootmgr
likes to change the boot order afterwards, this probably is not
what you want. The names of block devices should be more or less the same on
Linux and Moxnox.
The "EFI" file is actually a polyglot file that also conforms to the Linux boot
protocol, so it
should
also work on non-EFI GRUB. I have not tested this.
How to set this up is left as an exercise for the reader.
Hardware support
For amd64, everything is compiled for x86-64-v3, which covers more or less
anything manufactured since 2015 or so. Moxnox automatically uses and enables
AVX512 if it detects it. For qemu, you need to specify the
q35
machine type;
the default
pc
machine is ancient, and doesn't have PCI Express.
microvm
works too.
For aarch64, we're using LSE atomics, which require ARMv8.1. That means the
Raspberry Pi 5, but not any earlier models. Moxnox only supports ACPI, not
Device Tree, so for the Pi you will also need
https://github.com/worproject/rpi5-uefi
.
Unfortunately there is no
raspi5
machine type in qemu, but I have had success
with
virt
, and
sbsa-ref
works too.
Device support:
Block devices: NVMe, SATA, SDHCI (i.e. SD cards), virtio-block, USB mass
storage
Network cards: virtio-net, RTL8168, RTL8125
Input devices: USB HID, PS/2 keyboard, PS/2 mouse, virtio-input
Graphics: virtio-gpu, GOP framebuffer, VBE, VGA text console (pass
text=80x25
on non-UEFI boots)
Serial ports: virtio-console, x86 serial port, PL011 ARM serial port
USB: XHCI
Building
The easiest way to build is to pull the Docker containers
maharmstone/moxnox-ci-amd64
or
maharmstone/moxnox-ci-aarch64
, which contain the cross-compilers for
x86_64-pc-moxnox
or
aarch64-pc-moxnox
.
Then in the container:
$ git clone https://github.com/maharmstone/moxnox
$ cd moxnox
CMake will compile whichever of the submodules are checked out. For a minimal
system:
Make sure you specify Ninja - we need this as we're using C++ modules. CMake
defaults to Unix Makefiles, which don't work.
Finally:
gcc
,
llvm
, and
rust
are not compiled unless explicitly requested due to
their size.
hexyl
and
ripgrep
also need to be specified explicitly due to
their dependency on
rust
.
To build on Moxnox, as above, but you don't need a toolchain file:
cmake -GNinja ..
.
gcc
,
rust
,
hexyl
, and
ripgrep
can't yet be compiled in Moxnox, but
everything else works (eventually). You may need a lot of RAM and even more
patience. If CMake complains about
rust-libc
, make sure that you don't have
the Rust submodules checked out.

FAQs
What's missing?
Loads - but this
is
version 1.0. In particular:
A GUI
Support for different timezones
Support for different keyboard layouts
Locales and non-UTF-8 character sets
Any sort of security
Multiple users and groups
For performance issues and similar:
The userspace heap allocator could be a lot quicker (this is the bottleneck
when self-hosting)
TCP is slow, because we don't negotiate an MSS and keep to the default 64KB
window
We ought to be doing early writeback on memory pressure
There should be an LRU system to drop clean pages from the page cache...
...made worse by the fact that the dentry cache never gets pruned, so inodes
stay open until deleted
And obviously there should be more ports and hardware support.
How compatible is it with NT?
The contract is that the syscalls and low-level interfaces match those of NT,
but not the daemons or how the kernel itself is structured. This is in contrast
to what ReactOS aims to do, which is an exact recreation of Windows.
So:
Binaries are PE format rather than ELF, and have a
.exe
or
.dll
extension
C++ exceptions are done through SEH
POSIX signals are done through Asynchronous Procedure Calls
All the non-kernel kernel-like stuff gets done in
ntdll.dll
The rcx, rdx, r8, r9 calling convention matches that of Windows
And its C eccentricities match those of Windows:
sizeof(long) == sizeof(int32_t)
,
sizeof(wchar_t) == sizeof(char16_t)
,
sizeof(long double) == sizeof(double)
.
There's an awful lot of stuff in NT, but the interesting stuff that's missing
is tokens, the Registry, and I/O completion ports.
NT has a complex system where there's a virtual filesystem but it's hidden
(unless you use winobj), with the true path of a file hanging off the name of
its block device (so
C:\Windows\System32
might actually be
\Device\HarddiskVolume1\Windows\System32
).
I've not replicated any of that. Paths are POSIX-like: slashes rather than
backslashes,
/
as the root filesystem, and mounted directories. Unlike real
Windows,
NtCreateFile
resolves . and .., to work better with the dentry cache.
Other things I've deliberately not copied are the various forms of transactions,
which were a product of their time, and the idea of paged kernel memory, which
causes more problems than it solves.
How compatible is it with POSIX?
We have implemented 642 of the ~1,200 functions in POSIX 2024. This is the vast
majority of what's used in practice, with
gnulib
papering over some of the
cracks. Unlike Windows,
fork
is there. I've used
musl
for its mathematical
and cryptographic functions, and
mingw
for
printf
and some other things,
and
tre
for its regexes.
The POSIX functions are split over
ucrtbase
,
iphlpapi
, and
ws2_32
, as on
Windows, with anything that Windows doesn't implement put in
mnposix
.
I've borrowed liberally from Linux's best ideas: the dentry cache, large folios,
mapping the whole of physical memory, evdev.
Other POSIX shortcomings:
AF_UNIX is half-complete.
socketpair
works, including for SCM_RIGHTS (
ssh
uses this), but the normal client-server code doesn't work
mkfifo
creates an inode, but I/O to it does not get redirected to a buffer
as it ought to do
APCs (i.e. signals) only get delivered when a thread returns from a syscall.
So a program doing
while (true) { }
is currently unkillable.
How do I start sshd?
There's nothing that automatically starts daemons yet, so manually.
First generate the host key:
There's no passwords yet, so you will need to add a
/root/.ssh/authorized_keys
file so that you can connect. If you have trouble, double-check that /root is
owned by root, as sshd will ignore this file otherwise.
Then start sshd using its full path:
Can this run Windows programs?
No. Or at least, not yet.
We deliberately do not implement any Win32 DLLs, bar a few functions in
kernelbase
that the mingw runtime wants. A future improvement would be to
strip these out entirely, then port across Wine's versions of the Win32 DLLs.
Some parts of Wine, like
wineserver
and
ntdll
, we would not need as we are
already taking care of it ourselves.
How sloppy is this?
None of the substantive code was written by AI.
I used AI to help with the mechanical parts of porting (e.g. translating
autotools to CMake, replacing
ioctl
calls with
tcgetwinsize
, translating
the C structs into Rust), as well as to write some of the smoke tests (e.g.
cairo-test
,
mesa-test
).
Where Claude really shines though is in reviewing your own commits. You give it
a hash, and it tells you about the silly memory leak or deadlock that you left
in, before you can make a fool of yourself.
Why?
For funsies. Plus the only way of really learning how something works is to
have a go at writing it yourself.
Also, the NT kernel is
criminally
underrated, and pretty much unknown to
hobbyists. It had features that Linux took years and years to come up with its
own design for, such as
eventfd
and
pidfd
.
It's a shame that Windows keeps shying away from full POSIX compatibility. They
had a half-complete version in the early days, then more recently had WSL1, only
to then abandon it. And Nano Server was another cool idea, only again to be
itself abandoned. So this is my take on what I wish Windows had been like.

Lula’s Victory Offers Hope for Democracy and the Amazon

...
President of Brazil Luiz Inacio Lula da Silva (L) and UN Secretary-General Antonio Guterres attend the opening ceremony of the “Belem Climate Summit” as part of the COP30 Brazil Amazonia 2025 on November 6, 2025 in Belem, Brazil. | Wagner Meier/Getty Images
When Luiz Inácio Lula da Silva lost the first round of the Brazilian election and fell behind in the polls, I thought he would lose the election. So, the fact that he won is a stunning comeback. It took the three weeks between the two elections, hundreds of hours of street and online mobilization by Lula’s Army of Supporters, to defeat the conservative candidate, Sen. Flávio Bolsonaro. Another member of the Bolsonaro family, of course!
Lula’s winning magic was helped by a video. It’s a clip between the two men from their debate that rightfully deserves to be immortalized. In it, Bolsonaro
asks
him: “Why are 73% of the prisoners voting for you?” And the wise Lula answers: “I want 100% of the prisoners’ votes. Including your dad’s vote!” The people in the studio laughed. This exchange made Brazilian society laugh too, wake up, and think, after seeing a dynamic performance by Lula on live TV. It was the opposite of former US President
Joe Biden
in that infamous debate.
Bolsonaro (son of the ex-president
Jair Bolsonaro
who is imprisoned), who had pledged to join President Donald Trump’s “Shield of the Americas” security and political initiative, is the big loser. Flávio
reportedly fled
Brazil
after losing. Nobody has to be a genius to advise him: “Flávio, you lost. Concede with dignity. Don’t follow Trump’s infamous playbook. Show some grace in defeat.” But Bolsonaro losing is great news not only for the people of Brazil, but also for the flora and fauna of the
Amazon rainforest
.
Thus, Lula, who is a former worker, a unionist, and a pragmatic politician, prevents the return to power of the far-right with the Bolsonaros.
Thus, Lula wins a fourth term as Brazilian president, after a dramatic run-off. The crucial matter is that Lula, alone, defeated
Elon Musk
,
Mark Zuckerberg
,
Donald Trump
, and Flávio Bolsonaro together. After all, defeated are those who stop fighting! Musk said Brazil’s presidential election results do not “add up.” Relax, Mr. Trillionaire! Next to Lula, the Amazon rainforest won big time, ensuring it will not become a place for giant companies worth billions who want to mine for diamonds, gold, and extract petrol from its lands.
And Anne Applebaum
wrote
in an X post: “In one day, two politicians—Bolsonaro in Brazil and Vucic in Serbia—with ties to Trump and his family have lost surprise elections, thanks to high turnout. The rise of the international far-right is not inevitable.”
Lula has four fingers on his left hand! The one finger that’s missing, he lost at 17 years old when he was working as a metalworker and a mechanical lathe crushed his pinky finger. As he has said, “I arrived at three in the morning [at the hospital] smelling like work overalls, smelling like grease” and he looked so bad that the doctor didn’t bother to save his finger. In his eyes, that was the result of
poverty
.
During his years in power, Lula has supported democratic institutions and made important progress on protecting the forest—there is a web of laws protecting the Amazon now–and local communities who depend on it for their survival, but of course, for a few analysts, he had a mixed record in other areas. The economy has problems, but the same happens in countries like Germany and Japan.
Someone must acknowledge that
deforestation
has dropped drastically under Lula’s government, which has “set a target of completely halting illegal deforestation by 2030.” It reactivated the Amazon Fund, which is a mechanism backed by countries like Norway to finance conservation and monitoring, and stepped up enforcement through satellite imagery and policing. Lula also launched on November 6, 2025 the
Tropical Forests Forever Facility
to help developing nations to keep their forests intact.
The win in Brazil, the win in Serbia, the probable win in
Israel against Prime Minister Benjamin Netanyahu
's disastrous far-right coalition, and the upcoming midterms in the US, which will also test control of Congress, show that the power belongs to the people. That’s
democracy
in other words, and the people must have the final say.
Thus, Lula, who is a former worker, a unionist, and a pragmatic politician, prevents the return to power of the far-right with the Bolsonaros. So, this is a great result not only for the
workers
and democracy, but also for the giant Amazon lung. An electoral win for all the species that have lived there for thousands of years! Money is not above everything as capitalism’s big corporations teach, while in the end, the poor get crumbs if they’re lucky. The “pro-worker” left, headed by Lula, may have its own problems, but it is far better for society and the environment. The right thinks mainly of the plutocrats and the big profits; it leaves barbarism, which is a society in ruins.
The tireless Sen.
Bernie Sanders
(I-Vt.) said about Lula’s victory: “He will continue to fight for Brazilian workers and democracy over the next four years.” All the
progressives
and their grassroots movements around the world breathed the fresh air of the Amazon again.

A
Pew Research survey
released in October 2026 found that roughly 6 in 10 Americans – including 4 in 10 Republicans – believe there’s too much inequality in the U.S. And a growing share from both major political parties state that the economy needs to be fundamentally rebuilt to address this.
This sentiment has, however, been difficult to convert into political results. Public support for California’s proposed wealth tax on billionaires
has been waning
ahead of the midterms, for example, and in 2025, Republicans passed President Donald Trump’s
sweeping legislation
that included tax cuts for the wealthy while cutting safety net programs.
I’m an economist
who has been studying inequality for about two decades. My research
confirms the trend
of rising inequality since 1980, driven by the wealthiest pulling away not just from the middle class, but also from the “merely wealthy.” Overall, recent research underscores how
policy choices
– including taxation and public spending – enabled this 40-year rise in inequality.
Some policies enacted more recently appear to be accelerating this trend.
An analysis
by the Institute on Taxation and Economic Policy, a nonpartisan research organization, concluded that policy changes since the start of 2025 have imposed higher costs on everyone except the top 1%.
Inequality by the numbers
Recent federal data shows that
wealth inequality continues to grow
. The top 1% saw their share of wealth increase from 31.7% to 32.5% just between the first and second quarters of 2026, a jump of over $8.5 trillion. That caps a steady climb from 30.9% in the last quarter of 2024 – and from 27.4% in 1999.
These recent gains come at the expense of the middle class – the 40% between the bottom half and the top 10% – who hold only 28.8% of all wealth despite being a group that’s 40 times larger than the top 1%. And the middle’s share is shrinking, down from 32.9% in 1999 and 30.2% at the end of 2024, according to the data.
But the ultra-wealthy, those in the top 0.1%, are pulling away even from the rest of the rich, the data shows. This tiny elite owns 15% of all wealth – almost half of all the wealth of the top 1%. Both the top 0.1% and the next 0.9% saw their share of wealth increase, but the top 0.1% captured two-thirds of the gains between the first and second quarters of 2026.
Even within the highest echelons of wealth concentration, these two groups are on different trajectories.
Crucially, the wealth of the top 0.1% is
disproportionately boosted
by corporate profits, which are
up sharply overall
. The top 0.1% reap the most from this growth because their portfolios’ value has soared on the promise of future increased profitability that’s driving up stock prices – especially thanks to the tech and artificial intelligence boom.
How taxes play a role
Since President Ronald Reagan’s
tax cuts
in the 1980s, the U.S. tax code has become
less and less progressive
, often through policy changes supported by both Republicans and Democrats.
The common argument for tax cuts is that they stimulate growth, but a growing body of research –
including international studies
– doesn’t back that up. A
2025 Brookings report
notes that U.S. tax policy has gone through massive changes throughout history without any discernible effect on growth.
Nonetheless, congressional Republicans used their narrow majorities in 2025 to pass Trump’s sweeping policy and tax bill,
which included provisions
making most of his 2017 tax cuts permanent. Those included the historically low top-income tax rate and the
lowest corporate tax rate since 1940
.
While many voters cite affordability as a top concern, concerns over inequality have increasingly been part of this debate.

It’s also important to understand that the top 0.1% have a different tax exposure from the rest of the top 1% because
the composition of their wealth
is different. They own as much in stocks and mutual funds as the next 0.9%, a group that is nine times larger, and those holdings are where most of their recent gains came from.
Furthermore, roughly three-quarters of the top 0.1%’s wealth portfolio consists of
corporate and business ownership
, allowing them to benefit from the Trump tax cuts in multiple ways – including lower tax rates and more opportunities to defer or avoid tax liability. Their massive holdings of stock mean that they can
borrow against it for cash
, usually tax-free, rather than having to sell shares.
By contrast, below that elite, real estate
is a much more important component
of wealth, while corporate equity is a smaller and smaller share. For the middle class, nearly two-thirds of wealth is held in their homes and retirement savings, while corporate and business ownership accounts for only 15%.
The new drivers of inequality
Much of the inequality debate focuses on the role that taxation has played. But other recent policy changes have shifted different kinds of costs on to low- and middle-income earners, while leaving the wealthy relatively unscathed.
One example is a provision in Trump’s 2025 legislation that allowed federal healthcare subsidies through the Affordable Care Act to lapse. Insurers and analysts expect the number of people signing up for coverage through ACA plans to drop by
about 5 million
due to higher premiums and face much higher out-of-pocket costs.
The spike in energy costs, including gasoline, diesel and heating oil, is another case in point. They disproportionately affect
low- and middle-income consumers
but barely dent the budgets of the wealthy – while
boosting the profits
of companies engaged to the extraction, processing and transportation of oil. This divergence has been especially pronounced since the start of the conflict with Iran in February 2026, which
has pushed up
the global price of oil.
Then there are tariffs, which are fundamentally a consumption tax on imports. Economists at the New York Federal Reserve have found that these
levies have inflicted a heavy hit
on many common consumer goods. They estimated that prices for these items, which make up a much larger share of household budgets among the nonwealthy, would have fallen on average by 1% over the year without the tariffs. Instead, they have risen by 2.9%.
This acceleration in the redistribution of wealth from the middle class to the very top, in short, has an array of drivers. But they’re not inexorable forces of history. As economist Thomas Piketty put it in “
A Brief History of Equality
,” published in 2022: “Inequality is first of all a social, historical, and political construction.”

Japan's GMO urges customers to shut down PCs amid ransomware threat

The GMO Group has urged customers to disconnect their systems from the internet and shut down computers after a threat actor who breached the company’s Onamae Desktop Cloud threatened to launch a ransomware attack today.
The company later confirmed that data belonging to both the company and its customers had been published online.
The alert concerns a
cyberattack on Onamae Desktop Cloud
, a popular VPS provider in Japan operated by GMO Internet, a member of GMO Internet Group and one of Japan's largest domain registrars.
Last week, the company announced it detected an intrusion on October 20 that could have installed malware on up to 26,739 customers' servers.
To minimize the risk, the company shut down the servers and reduced service availability before launching an investigation.
The internet company assured customers that their payment information had not been exposed but warned that MetaTrader 4 and MetaTrader 5 (MT4/MT5) credentials and trading-account details may have been exposed or compromised. It urged customers to reset their passwords and terminate active sessions.
Cyberattack escalation
Subsequent updates from the company
confirmed that data had been stolen
and that the attacker was demanding a ransom of ¥8 billion ($50 million), which GMO said it would not pay. Instead, the company announced it would compensate each customer ¥5,000 ($30) for the inconvenience caused.
On October 26,
GMO warned
that threat actors planned to leak customer information online and trigger a ransomware payload planted on customer servers earlier in the attack.
The next day, the company
asked customers to disconnect their PCs
from the internet, shut them down, and unplug all cables before noon, while it worked with Trend Micro to recover from the cyberattack.
“Once you have a backup, disconnect the network, power it down, and unplug the cord that connects to your PC,” advised GMO to customers.
Instructions to customers
Source: GMO
The company said it was scanning customer systems to determine whether malware was still present, and offered equivalent PC replacements to those who suffered damages from a ransomware attack.
In a report published earlier today, GMO confirmed that the threat actor had
published company and customer data
, prompting efforts to verify the authenticity of the leaked information.
For customers whose information was exposed, GMO said it will consider additional financial compensation.
It appears that the attacker never acted on their threat, as no ransomware was activated on customer machines.
The company
warned people and the media
not to disseminate the exposed information, announcing it will take legal action against those who do, while reaffirming its refusal to pay the attackers.
OpenAI confirmed GPT-6.1 Terra is safer overall than some of its older models, but its safety testing also found other problems.
According to OpenAI, GPT-6.1 Terra showed higher rates of exfiltration, destructive actions, and attempts to bypass restrictions than GPT-6.1 Sol and GPT-6 Astra.
OpenAI performed simulations across approximately 48,690 matched tasks and found that Terra received 22 severity-3-or-higher flags, or 0.045%.
For comparison, GPT-6 Sol received 38, while GPT-5.6 Sol received 61.
"GPT-6.1 Terra received approximately 42% fewer severity level 3 or higher flags than GPT-6 Sol and 64% fewer than GPT-5.6 Sol," OpenAI noted in its
system card
.
Cybersecurity Safety Training and Evaluation (Higher is better)
However, that is no longer the case when you compare Terra with other newer models on less severe behaviors.
"Relative to GPT-6.1 Sol and GPT-6 Astra, we observed higher rates of flags for concealing uncertainty, circumventing restrictions, exfiltration, other misalignment, destructive action and inbound prompt injection," OpenAI explained.
Terra is clearly safer overall, but we can't overlook the other potential security issues it has, and this is true for all models shipping in the market, including Claude.
Terra also performed more unauthorized actions in one test
OpenAI also tested what happens when Terra needs to deal with messages from other AI agents while working through blocked coding tasks.
Terra attempted to communicate with those apparent peers in 65% of tests and ultimately performed the specified unauthorized action in 13.75%, or 11 of 80 samples.
OpenAI found that GPT-6.1 Sol did so in just 1.25%.
"These results indicate that performance is comparable to 6.0 Sol," OpenAI noted, adding that much of the regression against GPT-6.1 Sol involved promises of future help that Terra indicated it would not actually carry out.
OpenAI warns that these tests were conducted in simulated environments, so the results may not necessarily reflect how GPT-6.1 Terra behaves in real-world production environments.
But we still aren't seeing meaningful improvements across every area of security, even as these companies claim their models can control computers and code better.

Check whether the device still works if the app or the company's servers go away.
Look at the warranty length and how owners describe getting a replacement.
Read this before the numbers
Reviewers aren't hiding anything.
Most reviews are made in the first days or weeks with a new unit. That's too early for most failures, and it's hard to test a company's support.
Owners post when something goes wrong.
Nobody starts a thread to say their robot vacuum still works, so these numbers show what owners worry about, not how often things break. For scale: across all topics,
56%
of owner opinions and
15%
of reviewer opinions are negative. Reliability (
70%
) and apps (
71%
) are still well above the owners' own average.
Topic grouping matters.
If we also count mixed topics such as "Value & Support" or "Responsiveness & Key Reliability", owners bring up reliability
2.4
times as often
instead of twice
, and more in
all 17 categories that have owner opinions
. We lead with the stricter number. The same goes for apps: mixed topics like "Connectivity & Battery" are left out.

AI bots flooded 2023 UK government consultation on disposable vapes ban

AI bots flooded a government consultation with tens of thousands of fake responses in a failed attempt to stop the UK’s ban on disposable vapes.
Three-quarters of all the responses to the 2023 consultation on the tobacco and vapes bill were machine-generated, in what is thought to be the first coordinated attempt to use AI to derail health policymaking in the UK.
The attempt to manipulate the outcome of the consultation was disclosed on Tuesday in research published in the journal Tobacco Control by the health policy experts Dr Nason Maani, from the University of Edinburgh, and Prof Anna Gilmore, of the University of Bath.
The Department of
Health
and Social Care (DHSC) used bot-detection methods to identify that 90,835 of the 118,756 responses it received, 76%, were submitted by bots.
All but two of those 90,835 automated responses answered the same question in the “smoke free generation” consultation, in which they opposed Rishi Sunak’s Conservative government’s plan to ban disposable vapes. The submissions were “often duplicated many times and sent at high frequency from a small number of IP addresses”, the DHSC said.
The bombardment “appears to be the first documented instance of large-scale automated interference in a formal public health policy consultation”, the researchers said.
Maani added that while this attempt was identified, “the threat is that future campaigns become harder to catch, and what we can’t catch, we don’t know about. Such campaigns are a threat because they raise the possibility of a handful of powerful interests looking like a mass movement.”
The DHSC excluded the 90,835 automated responses from its decision-making. Keir Starmer’s Labour government inherited the tobacco and vapes bill in 2024 and passed it into law, including the ban on businesses selling or supplying disposable vapes.
Caroline Cerny, the deputy chief executive of Action on Smoking and Health, said: “Evidence that AI bots have been used to swamp a Department of Health consultation is deeply concerning.
“Given the tobacco industry’s history of seeking to undermine public health regulation, we need to be alert to the risk that technological advances can be used to further commercial interests around health policy and put safeguards in place.
“Decisions that affect public health must be based on sound evidence and expertise, not manipulated response numbers.”
Azzurra Moores, the associate director for information ecosystems at the thinktank Demos, described the attempt to derail the ban as “pretty alarming”.
“Public consultations are one of the main ways government opens up its decision-making, so any interference with them is a serious concern,” she said. “These findings are pretty alarming: if a consultation can be swamped like this, it stops telling policymakers what the public actually thinks and undermines trust in the process.
“This is a problem without easy answers. Every barrier that keeps bots out also makes it harder for real people to take part, and AI makes fake responses far harder to spot. Interference can adapt faster than departments can update their checks. Better screening and more transparency will help, but there’s no single fix.”
The DHSC said its “robust controls” identified the attempt to influence the consultation.
A spokesperson said: “We always have robust controls in place to prevent the manipulation of our public consultations, and those controls worked effectively in this case.
“As a result, the fake responses were removed, and the consultation helped inform the landmark action we are taking to create a smoke-free generation.
“We will remain alert to interference of this kind in future consultation processes, and we will not be deterred from doing what is necessary to promote healthier living.”
This month, I laid the traditional coding interview to rest. As a hiring manager at Anthropic, I stopped asking candidates to do them. It had a good run: Being able to quickly define problems and find elegant solutions was a weak but useful predictor for how successful you’d be on my teams. Small coding challenges in real code did tell us something meaningful about candidates.
That’s no longer true. There’s no more point in giving you a little React challenge than there is in quizzing people about assembly; Claude is now better at both. Our most impactful builders are successful regardless of how good they are at these tests.
The coding interview was, despite its ubiquity, never popular. I suspect that established engineers will still have strong reactions to its disappearance — if only for what it says about the evolution of our roles. Plenty of ink has been spilled to describe how AI is a challenge for junior developers, especially those trying to land a job. Now that I’ve seen junior people work with AI for a bit, I have a more hopeful take: Impact is less bounded by how many years of accumulated knowledge in frameworks and libraries you’ve gathered.
I’m seeing engineers who are comparatively new fly past people who are probably better coders and have been around much longer. Hunger beats tenure.
This post is my best advice for junior engineers, though “junior” is the wrong word. It’s really for engineers without social capital, status, or power.
All vision, no voice
First, know both your advantage and handicap.
Fresh eyes, even naive ones, have long been considered powerful. When I joined Stripe, founder Patrick Collison implored us newcomers to pay close attention to things that seem odd to us. His bet was that newcomers would spot friction and opportunities that old-timers had long stopped noticing.
In 1991, James March
wrote
that organizations depend on “maintaining an influx of the naive and ignorant”. When Orson Welles was asked how he got the confidence to try shots nobody had tried, he
said
: “Ignorance, sheer ignorance — you know there’s no confidence to equal it. It’s only when you know something about a profession, I think, that you’re timid or careful.”
When I joined Notion, one of my interviews involved designing an offline-mode architecture. I was baffled to hear that they considered it a “trick” interview, since an offline mode was deemed impossible. The data model was too complex for easily syncing an entire Notion workspace, and downloading individual pages was a user experience CEO Ivan Zhao would never allow. The data model complexity turned out to be true; the founder resistance didn’t. People considered it such common knowledge that nobody had checked. I, an ignorant newcomer, didn’t know better than to just ask.
It’s easy to read anecdotes like this one and see people making bad decisions. I cannot overstate how hard it is to spot these mistakes when you’re the one making them. Shortly after joining Notion, I wanted to outfit teams with large TVs to display live dashboards. I ran into organizational walls, failed, and didn’t care enough to start a whole fight.
A year later,
Ji Pei
joined as a new hire with the same idea. I scoffed and told him not to bother; I’d already tried. He’d already asked. The TVs showed up the next day. Somewhere in that year, I had become the old-timer.
The only problem with all that ignorant power: Nobody cares what you think. Most tech companies have layers of middle management to translate larger business goals into execution. Structurally, companies are often built around the idea of a few people green-lighting or blocking individual ideas. In a world where execution is expensive, you normally have to grind your way to some social status before the entire organization would “take a bet” on your idea. Org charts tend to change at a glacial pace, so even companies that believe in AI often expect junior people to simply execute their tasks faster rather than ambitiously go after business goals.
Well, good news: Execution isn’t expensive anymore.

“engineers are hired to create business value, not to program things.”
Attach yourself, he advised, to the parts of a company that make money. Start there: Understand what your company is actually trying to accomplish (or, at a larger one, what your group or department is). Then find the right altitude — understanding what kind of goals your manager’s manager has is often a useful proxy.
(2) Pick a radical idea: Come up with a few ideas that would, if successful, dramatically improve the chances that your organization achieves those goals. Be ambitious!
(3) Build it over a weekend: I have seen small groups and solo engineers fly past the usual process of writing product requirements documents (PRDs), getting buy-in, and lobbying for time with designers or product managers by building a working prototype.
(4) Focus on one good idea: In my experience, junior people often make the mistake of cramming multiple ideas into a single prototype, hiding three excellent ideas among 20 bad ones. If your prototype involves the creation of a new programming language, a backend, and also somehow mobile apps, you’re not going to be successful. The point of creating a working prototype is to communicate an idea so well that leadership quickly understands both the opportunity and that you’re the one who can run with it.
(5) Lean into your fresh perspective: If you’re working on something user-facing, you have a unique amount of empathy for users and thus a much better sense for how the product works or doesn’t work for them. My colleagues at Slack and Notion had a hard time internalizing what using Slack or Notion is like as an external user.
If you’re working on infrastructure or tooling, you have the benefit of never having learned all the reasons things are considered “impossible”.
The future is bright
I don’t think the coding interview is going to come back. It’s easy to get sentimental given how many copies of “Algorithms and Data Structures” were bought in hopes of unlocking good jobs and a better future — or how the death of the coding interview is another milestone in software engineering reaching a new level of abstraction.
At the same time, as a longtime hater of promotions by tenure, I can’t help but be optimistic. I’ve already seen my fair share of popular apps and products made this way.
At Anthropic, people got so used to using Claude Code as a command-line interface (CLI) that it took two relatively new engineers (
Anthony Morris
and
Alice Zhao
) to whip up a working prototype over one weekend. The first public version shipped roughly eight days later. You won’t be surprised to hear that a good graphical interface for Claude Code is a very popular product.
I'm probably not the only manager trying to figure out how to interview for people who build well with AI. I haven't quite gotten there yet — but I'm scanning resumes and portfolios for little prototypes that exhibit taste, empathy, and principled thinking. If you have figured out something better, I'd love to hear how.
We are expanding our partnership with the General Services Administration (GSA) through a new agreement that gives government partners a 40% discount on Claude Enterprise, Claude for Government, and the Claude API. For the first time, the discount applies across every product surface, including when agencies buy from us directly today and through cloud providers in the coming months. The discount also extends to state, local, tribal and territorial governments.
We are also launching a dedicated program to help agencies implement and make the most of their Claude use. These programs are commonly leveraged by our private sector customers and we’re looking forward to bringing those best practices to our public sector partners in the coming weeks.
Approximately 500 US federal, state, and local government organizations now use Claude. Weekly Claude for Government active users are up about eightfold since February, and usage across federal civilian agencies has grown about 20-fold in a year. Those organizations run some of the most important systems in the country, usually on tight budgets and with long procurement cycles. This agreement is built to support that work, so they can apply Claude to hard problems without a large upfront commitment.
The discounts offered through the agreement are estimated to save the government $1 billion. Agencies are not bound by a minimum spend commitment and will be able to pay for the usage they consume.
How Claude is helping public servants get more done
Government agencies are using Claude to solve some of their most important challenges. Examples include managing backlogs, records and forms, and modernizing old code. Some of the ways agencies are using Claude include:
Utah gave Claude Code to 34 developers across 10 state agencies. 80% had a working environment within 30 minutes, 71% reported saving 20+ hours by the end of the four-week pilot.
A US state CIO confirmed their team was able to respond to a ransomware attack in 8 minutes vs. the usual 2-3 days thanks to Claude.
A US federal security team used Claude Mythos to detect and patch the vulnerability that would have allowed for the takeover of a critical production system in about two days. A human penetration test the month before had missed it.
A cybersecurity professional at a major agency found and patched bugs in critical financial systems.
A US state IT developer moved nearly 900 API methods to a new framework in two days. The project had been scoped for a month.
A US state IT director used Claude Code to document 12 legacy code repositories, mapping 467 database tables and flagging 27 risks along the way.
More than half of the US states, some of the largest localities, and some of the countries largest critical infrastructure operators
participated
in our SLTT cyber defense program.
Meeting government security requirements
Agencies can use Claude for their most sensitive unclassified work. Claude for Government, which delivers Claude's coding and agentic work capabilities and provides near-feature parity with commercial offerings at a FedRAMP High authorization level, was made
generally available
on September 30.
Agencies building their own tools can use Claude through Amazon Bedrock or Google Cloud’s Vertex AI. On Bedrock, Claude is authorized for FedRAMP High, with select models authorized for DoD IL4 and IL5 workloads in AWS GovCloud. On Vertex AI, Claude is authorized for FedRAMP High.
Claude Enterprise is in process for FedRAMP Moderate authorization through the FedRAMP 20x program, marking the next evolution of how we are bringing the same innovative technology available commercially to the government.
Getting started
Government agencies can buy Claude at the OneGov discount through GSA's Multiple Award Schedule today. Whether your department or agency already uses Claude or is interested in using it, our Public Sector team will help discuss your options.

The University of New Mexico Health Sciences Center disclosed a cyberattack that caused system outages and disrupted patient care and academic activities.
On Monday, UNM Health, the university’s healthcare provider, began temporarily limiting new patient admissions, diverting ambulances to nearby hospitals, and suspending outpatient surgeries and appointments.
In an update on the incident, UNM said UNM Hospital and Sandoval Regional Medical Center remain open, and all clinics will resume scheduled appointments and procedures starting today, Tuesday, October 27.
Regarding emergencies, the healthcare organization advised that people should call 911.
However, today’s classes at its four health sciences schools are canceled, and nonessential HSC employees were instructed to stay home.
UNM Health is a
major statewide provider
of specialist care with more than 1 million patient visits annually.
Its flagship UNM Hospital in Albuquerque houses New Mexico’s
only Level I trauma center
, treating the most seriously injured patients.
Byod ransomware claims the attack
UNM did not disclose the type of cyberattack it suffered, but BleepingComputer found that a new ransomware group called Byod had claimed the attack.
In a post on their data leak site, the threat actor said it had compromised 36,000 systems across UNM’s main campus and hospital environments, including Active Directory forests, Group Policy infrastructure, the entire Microsoft Entra tenant, and two Oracle databases.
"This is your entire network and infrastructure compromised, the entire university COMPLETELY," the threat actor said.
They claim access to student and employee personal data, including:
Social Security numbers (SSNs)
HR, payroll, and Banner student records
Internal emails
Research data
Hospital appointment data
Patient information
Cerner EHR rosters
In an attempt to force a payment, Byod ransomware said it would take down the breach post after the university initiated communication, likely for negotiating a ransom.
BleepingComputer has reached out to UNM Health Sciences with a request for comment about these data theft allegations, but we have not received a response.
In a new post today, Byod ransomware said it would provide free keys that decrypt locked systems at healthcare facilities.
Caption
Furthermore, the threat actor promised to pay up to $2,500 for every patient affected by the cyberattack.
"We have morals and we have a heart, we are not villains, but we will still continue to hold companies responsible for bad security leading to the compromise of any customer data," the cybercriminals said.
However, the threat actor also said that it would keep all the stolen data.
Byod is a new ransomware gang that currently lists six victims on its data leak site. For three of them, it has already leaked the allegedly stolen data.
On its FAQ page, the threat group claims it is doing “pentesting” to expose vulnerabilities and hold data controllers accountable for breaches.
Source: BleepingComputer
Byod says no target is off-limits, but it selects victims after an initial assessment identifies a target of interest. The group says it focuses on “those at the top who look at consumers and/or customers as a number or another dollar in their pockets.”
The
UNM Health Sciences said today
that all its critical electronic systems are back online and all UNM Health hospitals are fully open. Ambulance traffic is now operating normally, and all clinics have resumed scheduled appointments and procedures.
The university said the quick recovery was possible due to IT security teams working "with external partners to secure the network."
"Their assessment determined that the event affected some end-user devices but did not penetrate core systems or servers," UNM Health Sciences Center notes.
Patients who received care at UNM hospitals, as well as staff and students who work and study there, are advised to remain vigilant for unsolicited communications and phishing attacks.
Ghostty 1.4.0 is a major release that includes large performance and
memory improvements, a 100% complete Kitty graphics implementation including
animation and relative placements (the first non-Kitty terminal to do so),
SSH integration improvements, and hundreds more improvements and fixes
across all platforms.
This release features
7 months of work
with changes from
172 contributors
over
2,889 commits
. Thank you to all the contributors,
maintainers, community moderators, translators, packagers, and users
who each helped make this release possible.
These release notes are painstakingly and lovingly hand-crafted
by human Ghostty maintainers, including the full changelog. They take
a combined 16+ hours to write, so please enjoy. 🥰
GHSA-4hwh-wx3w-3fqg
.
Paste protection didn't treat carriage returns as line endings, so a
paste could run a command without confirmation in programs that don't
use bracketed paste. This requires user interaction (copy-paste) to
trigger.
GHSA-mhff-mv4q-fp63
.
Malicious Kitty graphics commands could crash or hang Ghostty, force
huge allocations, or in limited cases read or delete files outside the
allowed temporary directories. This only requires displaying malicious
output.
GHSA-hcr9-7hcr-mjm8
.
Malicious terminal output could crash Ghostty, closing every window,
via tmux control mode. tmux doesn't need to be installed. This affects
Ghostty 1.3.0 and 1.3.1.
GHSA-hp9c-qp4q-cpw3
.
The same impact as above, via a tmux control mode layout with a
zero-sized or oversized pane. This affects Ghostty 1.3.0 and 1.3.1.
GHSA-w9q4-5jvv-mcv4
.
Clearing the screen into scrollback could corrupt memory if it deleted
the scrollback page holding a styled or hyperlinked cursor. This only
requires displaying malicious output, but only with a small
scrollback-limit
such as
0
. The default isn't known to be affected.
GHSA-2r63-vmw6-3m3c
.
A crafted directory name could make the zsh shell integration send
arbitrary escape sequences, such as silently replacing the clipboard via
OSC 52. bash was affected in a more limited way. This only requires
cd
-ing into a directory from untrusted content, such as a cloned
repository.
macOS:
GHSA-cw69-wm67-5pv8
.
Cmd-clicking a crafted OSC 8 hyperlink could open unsafe local files or
custom URL schemes, leading to arbitrary command execution. Ghostty now
blocks unsafe targets and confirms custom URL schemes. This requires
user interaction (cmd-click) to trigger.
macOS:
GHSA-mfw9-xcr3-7gfp
.
The same issue as above for links detected by the
link
configuration,
including the default URL matcher. This requires user interaction
(cmd-click) to trigger.
macOS:
GHSA-v8cw-fg4j-jcc4
.
Drag-and-drop text skipped paste protection, with the same impact as
above. This requires user interaction (drag-and-drop) to trigger.
macOS:
GHSA-mxqx-236q-wrv7
.
Opening a file whose name contains control characters could run a
different command than the one shown in the confirmation dialog. This
requires a crafted file on your system and confirming the dialog.
Note: I requested CVEs for the above advisories weeks ago, but GitHub
hasn't assigned them yet. If/when they're assigned, I will update the
above with proper CVE numbers.
Ghostty now supports Kitty graphics
animation
and
relative placements
.
These were the last major features of the Kitty graphics protocol that
Ghostty didn't support.
Programs that display animated images with the Kitty protocol, such as an
animated GIF shown with
kitten icat
, now animate in Ghostty instead of
showing a single still frame. Frame transmission, composition, and playback
control are all supported, and animations pause while the terminal isn't
visible. Relative placements let a program position one image relative to
another image's placement, so the child image moves along with its parent.
We also did a full conformance pass against the specification and Kitty
itself, fixing dozens of behavioral differences. For example, images now
scroll with text inside scroll regions (
#4323
), retransmitting an image
ID replaces the old image (
#6711
), and invalid image data now gets an
error response instead of silence, which could leave clients hanging. The
full list is in the
terminal capabilities
section.
Kitty graphics are faster, too. Image payloads are now parsed in bulk
with SIMD instead of one byte at a time, making large image transfers
about 16x faster
to parse in our benchmarks (64 MiB of image data,
x86_64 Linux), and drawing images costs much less per frame.
Our Kitty graphics implementation now covers 100% of the published
specification, making Ghostty (and libghostty) the first terminal
to do this outside of Kitty itself.
Ghostty now transparently compresses scrollback that isn't visible,
reducing the physical memory those pages use by
70% to 90%
for typical
text-heavy history. Compression only runs while the terminal is idle and
pages are decompressed on demand when you scroll back or search, so it
has no measurable impact on I/O throughput.
Thanks to compression,
the default scrollback limit has been raised from
10 MB to 50 MB
per terminal. On platforms that support compression, a
full scrollback still generally uses less physical memory than the old
10 MB limit did.
Compression lowers
resident
(physical) memory, not
virtual
memory, so
look at resident memory when measuring it. It is currently available on
macOS and 64-bit Linux.
Beyond scrollback, memory usage is lower in many places:
A new, empty terminal now uses about
16 KiB
of terminal page memory
on macOS, down from 128 KiB in Ghostty 1.3.1.
On macOS and Linux, memory freed by clearing or trimming scrollback is
now returned to the OS instead of being held until the terminal closes.
Hidden tabs release their GPU resources. On macOS, with one visible tab
and 20 hidden tabs, GPU memory dropped from about 385 MiB to 18 MiB.
Rebuilding them when a tab becomes visible again takes under a
millisecond.
There are performance improvements across the board in Ghostty 1.4
that yield significant gains compared to prior Ghostty versions.
The biggest win came from a surprising discovery: on macOS, the kernel
caps every read from a pty at about 1 KiB no matter how large the read
buffer is. Previously, Ghostty processed each read as it arrived, so per-read
overhead was paid every kilobyte, and the program writing output sat
blocked while we parsed. Ghostty now drains the pty on one thread while
parsing on another, raising end-to-end I/O throughput by
25% to 55%
on macOS (M4 Max, plain and Unicode text) over Ghostty 1.3.x.
VT processing itself is also much faster. In parser benchmarks, plain
ASCII text went from 128 MB/s to 725 MB/s (5.7x), CJK text got 3.4x
faster, and a 2.6 GB dataset of real-world terminal recordings
from
asciinema
is processed about 25% faster.
Together, these changes took
cat
-ing a 150 MB text file on macOS from
1.5 seconds to 566 milliseconds.
Other notable improvements:
Resize:
resizing a terminal with a large scrollback is about
6x
faster
(120x80 with 10,000 lines of scrollback), and 3x to 5x faster
with history full of CJK text or emoji.
Rendering:
the renderer holds the terminal lock
2.7x to 11x
less per frame, leaving more time for the I/O thread during heavy
output.
Copy and search:
formatting terminal contents as plain text, HTML,
or VT, which backs clipboard copy,
write_screen_file
, and scrollback
search, is 1.5x to 8x faster.
Launch (macOS):
about 15% faster from launch to visible window, and
27% faster to the first rendered frame.
Idle energy:
on macOS, the renderer's display link now sleeps when
there's nothing to draw. On GTK, hidden tabs stop rendering, matching
macOS.
Large OSC sequences:
OSC 52 clipboard payloads parse about
30x
faster
, and even short sequences like title changes are about 6x
faster.
The GTK app has a new rendering pipeline. It no longer uses
GtkGLArea
.
Instead, the renderer draws with EGL on its own thread, exports each frame
as a DMABUF, and hands it to GTK to display. Rendering is now
triple-buffered, which should greatly reduce tearing, and no OpenGL calls
run on the main thread anymore, which let us remove a number of
workarounds.
The most visible result is crisp text under fractional scaling. Text and
box-drawing characters are no longer blurry with fractional display
scaling such as 125% or 150% (
#1938
). We fixed this once before, but it
came back after upstream GTK changes. Ghostty now renders at the window's
true fractional scale, so every rendered pixel maps to exactly one pixel
on screen.
The new render surface needs a system EGL library (see
Changes for Package Maintainers
).
On GPU drivers that can't export DMABUFs, Ghostty falls back to copying
frames through the CPU, which is slower but works.
Ghostty now implements the
Kitty clipboard protocol
(OSC 5522) on both macOS and GTK. Ghostty 1.3 could parse the protocol
but didn't implement it.
OSC 52 can only read and write plain text. The Kitty clipboard protocol
lets programs running in the terminal read and write any kind of clipboard
data, such as images or HTML, and lets them pick among the formats on the
clipboard. Programs can also enable paste events (mode 5522), which tell
the program what formats a paste contains so it can read the one it
wants. This is how a terminal program can accept a pasted image, for
example.
Clipboard access follows the existing
clipboard-read
and
clipboard-write
configurations. By default, reads prompt for permission
and writes are allowed. The permission prompt shows a preview of the
clipboard contents, including images. Programs that send a password can
have your answer remembered for the rest of that terminal session. A new
clipboard-write-limit-bytes
configuration limits the size of a single
write (default 64 MiB). A write over the limit fails and leaves the
clipboard untouched.
You can now rearrange splits on GTK by dragging them, matching the macOS
feature introduced in Ghostty 1.3. When a tab has two or more splits, each
split shows a drag handle at the top. Grab the handle and drop the split
onto any other split, including splits in other tabs and windows. An
overlay shows which side of the target split it will land on. The terminal
contents, working directory, and running processes all move with it.
A new
drag-handle
configuration controls when drag handles are shown on
both macOS and GTK:
auto
(default),
always
, or
never
. With
never
,
splits can't be rearranged with the mouse. Hiding the handles was a
common request from users who found them in the way.
On GTK, splits can only be dropped onto other splits. Dragging a split out
to create a new tab or window is macOS-only.
Ghostty 1.4 includes dozens of improvements to core terminal emulation. We
now run
esctest
, Thomas Dickey's
terminal conformance suite, against Ghostty's terminal core in CI.
Alongside that, we fixed many differences from xterm in cursor movement
within margins, tab stops, character sets, mode reports, and more. You
can find the full list of related changes in the
terminal capabilities
section.
Ghostty also supports several new sequences, including soft terminal reset
(DECSTR), extended cursor position reports (DECXCPR), backarrow key mode
(DECBKM), and screen size reports in characters (
CSI 19 t
). Programs can
also now ask whether the terminal is visible using
visibility reports
(mode 2033), so they can stop rendering while hidden.
Keyboard encoding also matches xterm more closely, with fixes for
modifyOtherKeys
mode 2 and legacy Alt-as-Escape encoding of non-ASCII
keys.
Two new sequences are disabled by default because they can be abused by
untrusted programs, including ones running on a remote machine:
# Allow programs to resize the window (CSI 8 t)
vt-window-resize-allowed = true
# Allow programs to request screen checksums (DECRQCRA)
vt-xt-checksum-report = true
Ghostty 1.2 introduced
SSH shell integration features
as a work in progress. In Ghostty 1.4, they're backed by a new
ghostty +ssh
CLI action: a drop-in
ssh
wrapper that prepares the
remote session for Ghostty and then runs the real
ssh
with your
arguments forwarded unchanged.
ghostty +ssh user@example.com
# Or alias it so every ssh invocation goes through italias ssh='ghostty +ssh --'
Before connecting,
+ssh
installs Ghostty's terminfo on the remote host
so the proper
xterm-ghostty
TERM
value can be used, and forwards
COLORTERM
,
TERM_PROGRAM
, and
TERM_PROGRAM_VERSION
. If the terminfo
install fails (for example,
tic
isn't available on the remote), it falls
back to
TERM=xterm-256color
. Flags such as
--terminfo=false
,
--forward-env=false
, and
--verbose
control each step.
The
ssh-env
and
ssh-terminfo
shell integration features (still opt-in)
now call
+ssh
too. Previously, each shell integration carried its own copy
of this logic, which made up roughly a third of our shell integration
scripts. Now bash, zsh, fish, elvish, and Nushell all behave identically,
and you can get the same behavior from scripts or anywhere else by calling
ghostty +ssh
directly.
The terminfo install itself is also more reliable. Ghostty now always
installs its own bundled terminfo rather than accepting whatever
xterm-ghostty
entry the remote already has, and it reinstalls
automatically when a Ghostty update changes the terminfo. It also no longer
needs
infocmp
or Ghostty's terminfo on the local machine. Installs are
cached per host
and
port, so two machines behind one address no longer
share a cache entry. And
ssh-env
no longer silently overrides
SetEnv
entries in your
~/.ssh/config
(
#11518
).
The
+ssh-cache
command that manages this cache now takes positional
destinations (
ghostty +ssh-cache user@example.com
) and has a new
--prune=30d
flag. See the
breaking changes
if you
script against
+ssh-cache
.
macOS:
The minimum required macOS version for Ghostty 1.4 remains
unchanged (macOS 13 Ventura). Ghostty is now compatible with macOS 27.
GTK:
Ghostty 1.4 requires
GTK 4.18
and
libadwaita 1.7
, up from
GTK 4.14 and libadwaita 1.5 in Ghostty 1.3. This aligns with our
GTK/Adwaita version policy
.
Notably, Ubuntu 24.04 LTS doesn't meet this requirement. Systems with
older GTK or Adwaita versions can work around this requirement by using an
older version of Ghostty or the Flatpak package.
#14330
OpenGL (GTK):
The minimum required OpenGL version remains 4.3, but
Ghostty now renders through EGL instead of GTK's OpenGL widget. This
should be invisible for nearly everyone, but if Ghostty fails to start
with an EGL error, please make sure your GPU driver provides a working
EGL implementation.
We previously announced that Ghostty 1.4 would require macOS 14.
Nothing forced our hand to do this in this release, so we kept macOS
13 support.
We still plan to drop macOS 13 in a future release.
Apple
dropped security support for macOS 13 in the fall of 2025, so we
recommend upgrading regardless.
The following behaviors have changed in 1.4.0:
copy-on-select
has been reworked and now accepts
none
,
primary
,
clipboard
, or
both
.
The meaning of
clipboard
has changed:
it
previously copied to both the selection clipboard and the system
clipboard, and now copies only to the system clipboard. If you set
copy-on-select = clipboard
and want the old behavior, change it to
both
.
#12600
#12604
macOS:
copy-on-select
now defaults to
none
(previously
true
), so
selecting text no longer copies it anywhere and middle-click paste of the
selection no longer works by default. To restore the 1.3 behavior, set
copy-on-select = primary
. Note that an explicit
copy-on-select = true
on macOS now copies selections to the system clipboard, which is
different from 1.3.
#12600
#12604
macOS:
cmd+arrow_up
and
cmd+arrow_down
now run
jump_to_prompt
again,
matching Terminal.app and Ghostty 1.2. In 1.3, these keys were hardcoded
to scroll to the top and bottom and couldn't be rebound. To keep the 1.3
behavior, set
keybind = cmd+arrow_up=scroll_to_top
and
keybind = cmd+arrow_down=scroll_to_bottom
.
#12245
GTK: The default
ctrl+shift+page_up
and
ctrl+shift+page_down
keybinds
now move the current tab left and right (
move_tab
), matching Firefox,
GNOME Terminal, and VS Code.
jump_to_prompt
moved to
ctrl+shift+arrow_up
and
ctrl+shift+arrow_down
, so programs running in
the terminal no longer receive those keys. If a program you use needs
them, unbind them with
keybind = ctrl+shift+arrow_up=unbind
and
keybind = ctrl+shift+arrow_down=unbind
.
#4998
#12458
The list below contains deprecations that remain compatible today through
a compatibility layer, but may break in a future release if they are
ignored:
scrollback-limit
has been renamed to
scrollback-limit-bytes
, to make
room for the new
scrollback-limit-lines
.
#13473
copy-on-select = true
is replaced with
copy-on-select = primary
on
Linux and FreeBSD, or
copy-on-select = clipboard
on macOS.
copy-on-select = false
is replaced with
copy-on-select = none
.
#12600
#12604
There is no set timeline to remove these deprecations, but we recommend
adapting to the new configurations sooner rather than later to avoid
any possible disruptions in the future.
Scrollback history is now transparently compressed while the terminal
is idle, reducing the physical memory used by compressed scrollback by
70% to 90% for typical text. Compression is available on macOS and 64-bit
Linux and can be disabled with the new
scrollback-compression
configuration. Because of this, the default scrollback limit has been
raised from 10 MB to 50 MB, which on average still uses less memory than
a full scrollback did previously.
#13264
A new configuration
scrollback-limit-lines
limits scrollback by number
of lines instead of bytes. The existing
scrollback-limit
configuration
has been renamed to
scrollback-limit-bytes
(the old name continues to
work). If both are set, the first limit reached applies, and both accept
unlimited
.
#13473
copy-on-select
now accepts
none
,
primary
,
clipboard
, and
both
and no longer affects middle-click paste (see
middle-click-action
).
clipboard
now copies only to the system clipboard, so use
both
for the
previous behavior. The default on macOS is now
none
. See the
breaking changes
for migration details.
#12600
A new configuration
middle-click-action
configures the behavior of
middle-clicking:
primary-paste
(default) pastes from the selection
clipboard,
clipboard-paste
pastes from the system clipboard, and
ignore
does nothing.
#12478
A new binding action
move_tab_to_new_window
moves the current tab into
a new window of its own. It is also available in the command palette.
#2630
A new CLI command
+explain-config
prints the documentation for a
configuration option or binding action, e.g.
ghostty +explain-config font-size
.
#11546
The
+explain-config
and
+show-config
CLI commands now page their
output through
$GHOSTTY_PAGER
or
$PAGER
(falling back to
less
) when
run interactively. Paging can be disabled with
--no-pager
or by setting
the pager to an empty value.
#11940
A new configuration
drag-handle
controls when the split drag handles
are shown:
auto
(default),
always
, or
never
.
#13706
#13709
Scrollback search now wraps around when navigating past the first or
last match.
#11449
A new configuration
link-osc8
(default
true
) can be set to
false
to
disable OSC 8 hyperlinks entirely. Disabled OSC 8 hyperlinks are not
highlighted, previewed, copied, or opened.
#13634
Processes running in Ghostty now receive a
GHOSTTY_SURFACE_ID
environment variable that uniquely identifies the terminal they are
running in.
#12027
The right-click context menu now has a "Close Split" item.
#11173
#11174
I/O throughput is 25% to 55% higher on macOS by reading from the pty
concurrently with parsing previously read output.
#13209
VT processing is significantly faster across the board. Plain text is up
to ~6x faster, real-world output (measured against a large asciinema
dataset) is ~24% faster, grapheme-heavy output is ~3x faster, and DEC
special graphics (line drawing), repeated characters (
REP
),
hyperlink-heavy output, and scroll regions are all faster.
#13220
#13226
#13231
#13294
#13625
#13826
#14356
Large OSC sequences, such as OSC 52 clipboard writes, are parsed ~30x
faster and small OSC sequences, such as title changes, ~6x faster.
#14011
#13565
Resizing with reflow is ~6x faster with large scrollback and 3x to 5x
faster with scrollback heavy in wide characters such as CJK or emoji.
#13537
#13827
Terminals use significantly less memory. A new terminal now uses ~16 KiB
of physical memory for its screen instead of 128 KiB on macOS, every
terminal page uses 30% less memory, and memory freed from scrollback
(such as by clearing it) is now returned to the operating system.
#13240
#13245
#14130
#14137
#14138
Kitty graphics are faster. Large image transfers are parsed in bulk using
SIMD, zlib-compressed images decompress ~17% faster, pixel format
conversion avoids an extra copy, and the per-frame cost of drawing images
is much lower, especially with Unicode placeholder images on screen or
long scrollback.
#13270
#13281
#13987
#14422
#14780
#14789
Formatting terminal contents is 1.5x to 8x faster, which speeds up
clipboard copy (plain, HTML, and VT),
write_screen_file
and related
actions, and scrollback search.
#13587
command-palette-entry = clear
removes all command palette entries,
including the default entries.
#12682
window-padding-balance
has a new value
equal
that balances padding
equally on all four sides without capping the top padding.
#11491
theme
now expands
~
to the home directory in theme file paths,
including in separate light and dark themes.
#13840
+list-themes
now supports
g
and
G
to jump to the first and
last theme, and
ctrl+d
and
ctrl+u
to page down and up.
#13681
#14607
The terminal inspector can now copy terminal I/O events or export them
to a file.
#13519
Bundled themes updated to
release-20261019-151001-86a776d
.
This adds 356 new themes and renames or removes none. The colors of 10
existing themes changed upstream: Adwaita, Adwaita Dark, Atom One Light,
Catppuccin Frappe, Catppuccin Latte, Catppuccin Macchiato, Catppuccin
Mocha, Cursor Dark, Dark Modern, and Electron Highlighter.
Fix configuration parsing silently ignoring all settings after a comment
or blank line that happened to end at an internal buffer boundary. This
typically only affected long configuration files.
#13638
Fix a performance degradation where, after a long uptime, the renderer
rebuilt its full terminal state on every frame.
#13585
Fix the automatically created configuration file being empty instead of
containing the configuration template.
#13774
+edit-config
works when
$EDITOR
or
$VISUAL
contains arguments,
such as
zed --new
.
#11897
Mouse selection improvements: dragging after a
ctrl
/
cmd
triple-click
output selection now extends the selection by command output, autoscroll
stops when the screen switches (e.g. to the alternate screen), a force
touch on macOS selects the word at the press location without starting a
drag, and releasing a drag no longer activates a link or prompt click.
#12830
Double-click word selection no longer continues across hard line breaks,
and double-clicking either half of a wide character (such as CJK) selects
the whole word.
#14354
#14391
Wide characters at the edges of a selection are now consistently rendered
as selected and included when copying, including when the wide character
wraps onto a new internal page.
#14632
#14651
Triple-click line selection no longer pulls in neighboring prompt text
when clicking blank cells between OSC 133 prompt boundaries.
#14553
Link detection and double-click selection no longer merge prompt text
with the command text next to it when shell integration is active.
#12435
File paths opened with
cmd
/
ctrl
-click no longer include trailing
spaces, which broke opening paths printed by some TUIs.
#13505
Mouse releases are now reported to the program that received the mouse
press when clicking at a shell prompt with click-to-move enabled. This
fixes double-click selection in programs like fzf's
ctrl+r
history
search.
#14710
Shell redraws after a resize are no longer processed at the old terminal
size. This fixes one cause of duplicated or misplaced prompts after
resizing.
#14706
Scrolling, such as clicking in the scrollbar, now works with very large
scrollback (millions of lines).
#13048
Custom
command-palette-entry
actions with string parameters, such as
set_tab_title
, no longer have their parameters escaped when run from
the command palette.
#13609
HTML clipboard copies no longer include a superfluous trailing newline.
#13543
Copying as VT (
copy_to_clipboard:vt
) and VT screen files now preserve
OSC 8 hyperlinks, empty gaps between text, and cells that only have
a background color, such as colored status bars. VT screen files also
keep trailing blank rows.
#14711
#14725
#14766
The mouse pointer now restores the shape set by the running program
(OSC 22) after releasing modifier keys instead of resetting to the
default.
#14128
Custom shaders no longer receive swapped selection foreground and
background color uniforms.
#14460
Ghostty no longer floods the logs with "adjusting page capacity"
messages during output with many styles, graphemes, or hyperlinks.
#14631
Fix stale wrap and prompt state on rows reused after scrolling or
erasing, which could cause incorrect copy, search, selection, and reflow
results.
#14010
Fix stale rendering of the previous row after erasing or deleting a
wrapped wide character.
#14054
Fix a freeze when reloading the configuration while a program is flooding
the terminal with queries, such as color queries.
#14833
+list-themes
no longer crashes on some keys when the search
matches no themes, and the keypad down key now moves one row instead of
21.
#14612
#14605
Fix crashes in scrollback search after clearing the scrollback, resizing,
or erasing history.
#11957
#13274
#13282
Fix crashes and viewport corruption when resizing with scrolled-back
history or with the cursor near the bottom of the screen.
#12300
#12907
#12935
Fix a use-after-free crash when clicking or selecting text during heavy
output.
#12463
Fix a possible crash when reflowing hyperlinks during a resize.
#13524
Fix possible crashes or memory corruption when scrolling or erasing rows
across a page boundary that needed more capacity.
#13394
#13397
Fix possible crashes and memory corruption found via fuzzing when
printing causes a page to grow, or after clearing the screen into
scrollback.
#11261
#13997
Fix many latent crashes and undefined behavior in selection, pins,
search, title and working directory updates, and resize error handling.
#12894
#13275
#13278
#13367
Fix a possible crash or corrupted input when many pty writes are queued,
such as during large pastes.
#13659
Fix an out-of-bounds access when IME preedit text with wide characters
is composed between existing wide characters, such as with Korean input.
#12479
Fix a crash when pressing or releasing mouse button 11.
#14759
Fix the
write_screen_file
,
write_scrollback_file
, and
write_selection_file
actions leaking two file descriptors on each use,
which could eventually prevent opening new terminals.
#13644
Fix memory and file descriptor leaks in terminal I/O, including for writes
in read-only mode and files read via the
input
configuration.
#13574
#13579
#13931
vt: Kitty graphics animation is now fully supported: frame transmission,
composition, animation control, and rendering.
#5255
#13943
vt: Kitty graphics relative placements (
P=
,
Q=
,
H=
,
V=
) are now
supported, allowing images to be positioned relative to other images.
#13939
vt: Support the Kitty graphics transient image usage hint. Transient
images are evicted first when image storage is full.
#13389
vt: The Kitty clipboard protocol (OSC 5522) is now implemented on macOS
and GTK, including paste events (mode 5522). Reads and writes follow
clipboard-read
and
clipboard-write
, and a new
clipboard-write-limit-bytes
configuration limits the size of a single
write.
#10549
#13962
#13993
#13995
#13998
#14002
#14061
vt: Support visibility reports (mode 2033 and
CSI ? 998 n
), which tell
programs when the terminal is not visible, such as in a background tab
or on another workspace, so they can stop rendering.
#13494
vt: Programs can resize the window with the xterm
CSI 8 ; rows ; cols t
sequence if the new
vt-window-resize-allowed
configuration is enabled
(default off). The request is ignored in splits, windows with multiple
tabs, the quick terminal, and fullscreen, maximized, or tiled windows.
#1115
#14375
vt: Support OSC 133
click_events=2
, which reports prompt clicks with
row coordinates relative to the prompt.
#10865
#12953
vt: Support soft terminal reset (DECSTR,
CSI ! p
), which resets
modes, margins, and text attributes without clearing the screen.
#14538
vt: Support backarrow key mode (DECBKM, mode 67), which lets programs
choose whether backspace sends
DEL
(
0x7f
, the default) or
BS
(
0x08
).
#12226
vt: Support the DECRQCRA and XTCHECKSUM screen checksum reports, which
are mostly used by terminal test suites. Because a program can use these
to read the screen contents, they are disabled unless the new
vt-xt-checksum-report
configuration is enabled. The new
vt-xt-checksum-extension
configuration controls how the checksum is
calculated.
#14483
vt: Respond to
CSI 19 t
(report screen size in characters) and to
DECXCPR (
CSI ? 6 n
) extended cursor position requests.
#14633
#14673
vt: DECRQM now answers ANSI mode queries (
CSI Ps $ p
), reports DECECM
and other unimplemented ANSI modes as permanently reset like xterm, and
no longer truncates mode numbers above 32767 in its reply.
#12505
#14236
#14237
#14672
vt: Ghostty terminfo now advertises overline support (
Smol
/
Rmol
),
which lets tmux pass overlines through. DECRQSS SGR replies now include
overline and curly, double, dotted, and dashed underline styles.
#13649
#13653
#13470
vt: The terminfo
Se
capability now resets the cursor to the configured
cursor-style
instead of a steady block. This fixes programs like Neovim
leaving a block cursor behind on exit.
#12482
vt: OSC payloads are now limited to 8 MiB, Kitty graphics payloads to
65 MiB, and each cell to 64 combining codepoints, so terminal output
can't easily exhaust memory. This also fixes a memory leak on invalid
Kitty graphics data.
#12349
#13633
vt: Experimental support for the
Glyph Protocol
(APC
25a1
), which lets programs register custom glyphs. Ghostty parses
and answers requests but doesn't render registered glyphs yet.
#12352
#12930
#12937
vt: Parse the new program status protocol (OSC 7501), which lets programs
report whether they are idle, working, done, blocked, or failed. This is
the first terminal specification pioneered by the Ghostty project.
libghostty can parse it all, but the Ghostty GUI ignores it for now.
#14560
vt: Parse (but do not implement) the Kitty desktop notification protocol
(OSC 99).
#10467
vt: Parse (but do not implement) the Kitty drag and drop protocol
(OSC 72).
#13029
vt: More tmux control mode fixes, including crashes that running
tmux -CC
could trigger. tmux control mode is still not hooked up to
the GUI.
#11395
#11935
#14262
#14680
vt: Clearing the screen at a prompt (e.g.
ctrl+l
in bash or zsh) now
moves prior output into scrollback even when the prompt is not on the
last row. Previously, the output was erased.
#14660
#14668
vt: Kitty graphics: transmitting an image with an existing ID now
replaces the image and removes its old placements, as the spec requires.
Interrupted or failed retransmissions no longer leave stale images on
screen.
#6711
#13723
#13893
vt: Kitty graphics: images now move with the text when a program scrolls
with
CSI S
,
CSI T
, or scroll margins, and are clipped to the scroll
region.
#4323
#13935
vt: Kitty graphics: automatically assigned image IDs no longer collide
with IDs chosen by the program.
#2197
#13934
vt: Kitty graphics: delete commands now match the spec and Kitty. Point
deletes (
d=p
,
d=c
) only remove placements at that cell,
d=a
only
removes placements on the visible screen, range deletes accept empty
ranges, and deleting a missing placement no longer frees the image.
#13652
#13895
#13898
#13932
vt: Kitty graphics: command validation and responses now match Kitty.
This fixes missing responses for invalid image data that could hang
clients, false positive query replies, lost IDs in chunked transfer
replies, file transfers with an exact
S
size, and loads interrupted by
a non-chunk transmission.
#13889
#13892
#13896
#13897
#13933
#14811
vt: Kitty graphics: cropped source rectangles are no longer stretched,
and
X
/
Y
offsets are kept within the first cell.
#13890
#13891
vt: Kitty graphics: the cursor moves after tall images like Kitty does,
so consecutive images no longer overlap.
#13887
vt: Full reset (RIS) no longer resets
image-storage-limit
to the
default.
#13951
vt: OSC and APC sequences (such as Kitty graphics commands) canceled by
CAN or SUB, or aborted by another control character, are now discarded
instead of executed, matching xterm.
#14453
#14812
vt: With modifyOtherKeys level 2, control keys, keypad keys, and
alt+escape
now encode like xterm. F13 to F25, Help, and Menu now send
xterm's function key sequences in all legacy encoding modes.
#14144
#14145
vt: Legacy alt-as-escape encoding now sends the full UTF-8 sequence for
non-ASCII keys.
#14146
vt: Kitty keyboard protocol release events no longer repeat the typed
text for dead keys or level 5 keys on GTK, which caused duplicated
characters in programs like Neovim.
#13861
vt:
ctrl+alt+shift+backspace
now sends
ESC BS
in legacy key encoding,
matching xterm.
#14508
vt: UTF-8 mouse mode (1005) now encodes the button correctly, fixing
invalid reports for the back and forward mouse buttons.
#14532
vt: Foreground, background, and cursor colors reset with OSC 110, 111,
or 112 now follow later configuration changes, such as a light/dark
theme switch.
#13650
vt: Full reset (RIS) now restores palette colors changed with OSC 4.
#14480
vt: An empty OSC 22 now resets the mouse pointer shape to the default.
#14495
vt: Long desktop notifications (OSC 9 and OSC 777) with multibyte UTF-8
text are no longer dropped or shown as invalid UTF-8 when truncated.
#13795
#13811
vt: DCS strings now carry UTF-8 data. Previously, some UTF-8 bytes were
dropped, ended the string early, or started a new control sequence.
#14016
vt: C0 controls
0x10
to
0x1F
are now executed instead of printed
as text, and UTF-8 encoded C1 controls are ignored, matching xterm.
#14022
#14023
vt: Erasing a full line (
CSI 2 K
) now clears its soft-wrap state, so
erased rows no longer join together when the window is resized.
#13637
vt: The cursor and saved cursor keep the correct position when a resize
reflows text, fixing an extra line wrap or overwritten text after
resizing.
#12598
#14458
#14478
vt: Variation selectors (VS15/VS16) now apply to the preceding codepoint,
fixing the rendering of some ZWJ emoji such as the pirate flag.
#12596
vt: Combining marks printed after a character in the last column now
attach to that character.
#12581
vt: Characters above U+00FF, such as emoji, now print as-is instead of as
a blank while a non-UTF-8 character set such as DEC line drawing is
active.
#14554
vt: Single shifts (SS2/SS3) now apply only to the next printed character.
#14576
vt: Tab clear (TBC) fixes:
CSI 0 g
no longer sets a tab stop where
there wasn't one, and
CSI g
with no parameter clears the tab stop at
the cursor.
#13900
#14644
vt: Printing with autowrap (DECAWM) disabled clears the pending wrap, so
re-enabling autowrap doesn't cause a spurious line wrap.
#14652
vt: With reverse wrap enabled, moving left after restoring a cursor with
a pending wrap no longer jumps the cursor.
#14390
vt: Cursor movement respects margins and origin mode: CUB and backspace
stop at the left margin, and CHA, HPA, VPA, HPR, and VPR no longer apply
the margin offset twice in origin mode.
#14761
#14762
vt: Fix a crash when VS15 narrows a wide character under the cursor.
#13631
vt: Fix a crash or memory corruption after narrowing the terminal cuts a
wide character in half on the alternate screen or with wraparound
disabled.
#14509
vt: Fix a crash when a grapheme cluster widens in the last column and
wraps inside or below a scroll region with grapheme clustering (mode
2027) enabled.
#14552
vt: Fix a slow memory and performance leak in graphics-heavy sessions
where evicted Kitty images left their placements' tracked positions
behind.
#13656
vt: Fix a memory leak when an OSC color sequence contains more than two
requests.
#13239
A new
ghostty +ssh
CLI action wraps
ssh
and sets up Ghostty on remote
hosts: it forwards Ghostty's environment and installs Ghostty's terminfo
on the first connection to each host, caching successful installs. It can
be used directly (
ghostty +ssh user@example.com
) or as an alias
(
alias ssh='ghostty +ssh --'
) without shell integration. The
ssh-env
and
ssh-terminfo
shell integration features now use it for every
shell.
#12582
ssh-terminfo
now always installs Ghostty's bundled terminfo on remote
hosts instead of keeping an existing, possibly outdated,
xterm-ghostty
entry, and reinstalls it when a newer Ghostty changes its terminfo.
#13844
ghostty +ssh-cache
has been reworked with positional destinations, a
new
--prune
option, consistent output and exit codes, and error
messages that name the cache file. See the
breaking changes
above.
#12814
#13533
ssh-terminfo
now tells apart the same host on different ports, so
terminfo is installed on each of them.
ghostty +ssh-cache
accepts
host:port
destinations.
#14472
ssh-env
no longer overrides
SetEnv
entries in your
~/.ssh/config
.
#11518
#14854
bash: Failed commands now report their real exit status on Bash 4.4+,
so command finished notifications no longer report every command as
successful.
#14247
#14250
nu: Tab completion for
ssh
and
sudo
now works with external
completers such as carapace.
#13310
bash: The bundled bash-preexec, used only for Bash versions older than
4.4 such as macOS's
/bin/bash
, has been updated to 0.7.0.
#14120
zsh: Fix a stray
{
in the prompt and broken prompt marking when
PS1
or
PS2
ends with a bare
%
.
#11832
bash: Fix "command not found" errors in subshells that inherit
PROMPT_COMMAND
.
#11690
bash: Fix a syntax error when an existing
PROMPT_COMMAND
ends with a
newline.
#11621
bash: Fix extra blank lines at the prompt when using ble.sh.
#11644
bash: Fix the shell integration hook being added twice when it is
sourced again with an array
PROMPT_COMMAND
.
#14266
macOS: Support macOS 27. This fixes the layout and background color of
titlebar tabs, a thin border around the app icon, hidden titlebars
covering the top lines of the terminal with Reduce Transparency enabled,
and the Shortcuts "New Window" action opening two windows.
#13001
#13390
#14107
#14411
#12999
#13069
macOS: When a terminal's process exits, a native bar now appears at the
bottom of the terminal instead of text being written into the terminal.
Commands that fail or exit faster than
abnormal-command-exit-runtime
are highlighted in red.
#7649
#12251
macOS: Quitting, or closing a window, when multiple windows or tabs have
running processes now offers "Review Windows...", which steps through
each one so you can decide what to close.
#12742
#14062
macOS: The command palette now highlights matching text, matches
initials, searches action descriptions, and ranks results by where they
matched.
#12264
#13610
#13624
macOS: The search bar now remembers the last search and shares it with
other apps through the system find pasteboard, like Safari and
Terminal.app.
#12516
#12712
macOS: Screen readers such as VoiceOver are now notified when the
selection changes instead of reading a stale selection.
#12902
macOS: The AppleScript
terminal
class and the Shortcuts terminal entity
now expose
pid
(of the foreground process) and
tty
.
#11592
#10756
#11922
macOS: AppleScript tabs and terminals have a new read-write
name override
property to set or clear a custom title.
#12048
#14733
macOS: Middle-clicking a tab closes it with
macos-titlebar-style = tabs
.
#11962
#11963
macOS: The version in the About window now links to the release notes
for that version.
#11964
macOS: Updates that are downloaded and installed automatically no longer
prompt you to restart. Checking for updates manually still offers to
restart.
#13623
macOS:
toggle_background_opacity
now applies to every tab in the
window, and new windows inherit the current state.
#11583
macOS:
cmd+arrow_up
and
cmd+arrow_down
now run their configured
keybinds, which default to
jump_to_prompt
. Ghostty 1.3 always scrolled
to the top or bottom of the scrollback instead, ignoring the
configuration. To scroll to the top or bottom, use
cmd+home
and
cmd+end
.
#12245
macOS: In the configuration errors window, Return reloads the
configuration and Escape ignores the errors.
#12601
macOS: Ghostty launches about 15% faster to a visible window and draws
its first frame about 27% sooner.
#13722
macOS: Terminals that aren't visible, such as background tabs, now
release their GPU resources and rebuild them when shown again. With 20
background tabs, GPU memory drops from about 385 MiB to 18 MiB. Metal
buffers also no longer over-allocate when they grow.
#14017
#13490
macOS: Lower idle CPU and energy use. The display link now pauses when
there is nothing to draw, and unfocused terminals that are animating
draw at most once per display refresh instead of once per write.
#14035
#14068
macOS: Update Sparkle to 2.9.6, which fixes several security advisories
in Sparkle, including CVE-2026-47121 and CVE-2026-47122.
#14072
#14082
macOS: Global keybinds no longer stop working after macOS disables
Ghostty's event tap.
#12294
#12714
macOS: Fix IME composition issues. Korean text being composed is now
committed instead of lost when pressing an arrow key, and control-key
IME shortcuts such as Japanese input's
ctrl+j
no longer send control
characters to the terminal.
#11461
#12447
#12518
#12547
macOS: Text from input methods, dictation, and the emoji picker is now
sent as typed input instead of pasted text. Programs no longer treat
dictation as a paste, and switching input sources mid-composition sends
the pending text as keys, matching Terminal.app.
#13195
#13222
#13817
macOS: Unicode Hex Input can now enter characters outside the Basic
Multilingual Plane, such as emoji, typed as surrogate pairs.
#13733
#13737
macOS:
font-thicken
now also applies to IME preedit text.
#14230
macOS:
option+backspace
and other modified Backspace keys now report
their modifiers with the Kitty keyboard protocol instead of sending a
bare DEL.
#13871
macOS: Pasting and dropping text now prefer plain text over URLs, so a
path copied from apps like Transmit pastes as a path instead of an
sftp://
URL.
#13152
#13170
#13212
macOS: The search bar keeps focus when you click in it or on the
next/previous buttons, and the terminal's focus state is now correct
while search is open.
#11872
#11978
macOS: The Find Next and Find Previous menu items and the
navigate_search
and
end_search
keybinds now work correctly,
including while the search field is focused.
#12070
#12492
macOS: Pressing Enter in the search bar no longer blocks confirming an
IME candidate.
#12781
macOS: Clicking a command palette entry with the mouse now runs it
instead of closing the palette.
#11665
macOS: The command palette now gets focus and paste when opened from the
inline tab title editor.
#12524
macOS: Holding
cmd+t
to create many tabs now leaves the newest tab
focused.
#13725
#13985
macOS: Fix an empty "ghost" tab or window that could appear when a tab
was closed right after it was opened.
#12119
macOS: Titlebar tabs no longer disappear after creating a tab from
"Show All Tabs".
#12949
#13017
macOS: Double-clicking the window title now zooms the window with
macos-titlebar-style = tabs
.
#12219
macOS: Moving a tab with
macos-titlebar-style = tabs
on macOS 26 no
longer briefly shows the neighboring tab.
#14847
macOS: The inline tab title editor stays in place while the window is
resized.
#12220
macOS: Fix tabs flashing when switching tabs after a program changed the
background color with OSC 11, and the window chrome keeping the old
color after a light/dark theme switch.
#12825
#12828
#12822
macOS: The
macos-glass-regular
and
macos-glass-clear
options for
background-blur
now layer the glass over the background color, and
focused windows are no longer less transparent than unfocused ones.
#13914
#13928
macOS: The native titlebar no longer cuts off the end of the title when
using a custom
window-title-font-family
.
#14135
#14217
macOS: Fix terminals rendering at a stale size under heavy system load or
during rapid resizes from window managers.
#12143
macOS: Splits dragged into another tab or window now render immediately,
and the source window keeps keyboard focus.
#12343
#12338
macOS: The split zoom indicator no longer stays visible after the other
splits of a zoomed split are closed, such as with AppleScript.
#14703
macOS: The split divider now uses the standard row and column resize
pointers.
#13433
macOS:
window-save-state = never
now also stops macOS from taking
window restoration snapshots, which could stall focus changes between
windows.
#14506
macOS: Window state saved by Ghostty 1.2 or later is now migrated, so
windows and tabs are restored after updating Ghostty.
#12461
macOS: Tabs created while the screen is locked now initialize correctly.
#13639
macOS: Quitting now asks for confirmation when windows with running
processes are minimized or the quick terminal is hidden.
#13686
macOS: OSC 52 clipboard read confirmations no longer steal focus. If the
terminal is unfocused, Ghostty rings the bell and shows the prompt when
you return to it.
#13744
macOS: Splits in the quick terminal now also set
GHOSTTY_QUICK_TERMINAL=1
.
#12895
#12896
macOS: The quick terminal no longer reopens at a stale size after a
display is reconnected at a different resolution.
#13250
macOS: The "New Ghostty Tab Here" and "New Ghostty Window Here" services
now open the correct directory when given a plain-text path.
#12727
#12731
macOS: Working directories passed from Services, Shortcuts, and
AppleScript are now normalized, fixing Nushell and zsh
%1~
prompts.
#12614
#14051
macOS:
ghostty -e
no longer opens the command's file arguments as
extra terminals, e.g.
ghostty -e vim file.txt
.
#13748
macOS: Opening a
.command
file from Finder no longer corrupts
non-ASCII characters in its path.
#13862
macOS: The Shortcuts terminal entity now reports the correct kind,
title, working directory, and screenshot for new terminals.
#13007
macOS: The Shortcuts "New Terminal" action now works with commands that
have arguments and with a command field that was cleared.
#12391
#12392
macOS: AppleScript
send key
now works for character keys, not only
special keys like
enter
, and respects
macos-option-as-alt
.
#13205
macOS: Update pill fixes: update errors are now shown, "Install and
Relaunch" no longer asks for confirmation, and the cancel option is
hidden once an update can no longer be canceled.
#13540
#13562
#13612
macOS: The default app icon follows the system icon style again after
changing it in System Settings, and custom icons now apply to the app in
Finder.
#12180
#12344
macOS: The dock icon bell badge now appears when notification permission
was granted earlier without badge permission.
#12133
macOS: The Copy menu item is disabled when nothing is selected.
#12521
macOS: Menu items now show the correct shortcut for keybinds on physical
keys (e.g.
super+backquote
), uppercase letters, forward delete, and
the
scroll_to_selection
and
search_selection
actions.
#13888
#12039
#12011
#12281
macOS: The secure input indicator's popover arrow now points at the
icon.
#12249
macOS: Fix a rare permanent freeze after waking from sleep or changing
displays. macOS did not mark the app as "Not Responding", so it could
only be killed.
#14691
macOS: Fix a crash when closing a tab, most easily triggered with
undo-timeout = 0
.
#13359
#13364
macOS: Fix a crash when opening a new tab from a native fullscreen
window.
#13636
macOS: Fix a crash caused by a data race when reading cached terminal
contents.
#13646
macOS: Fix a crash when OSC 52 clipboard confirmation prompts overlap.
#13648
macOS: Fix crashes when CoreText returns null, such as for fonts without
a display name or under severe memory pressure.
#13642
#13679
macOS: Fix closed windows leaking with transparent titlebars (the
default), which made Ghostty and WindowServer use more CPU and memory
over time.
#13601
macOS: Fix a memory leak each time Ghostty reads terminal text, such as
for copy, Quick Look, or accessibility.
#12020
#12025
macOS: Fix an IOSurface memory leak when scripts rapidly create and close
terminals.
#13640
macOS: Fix a Mach port leak, and a gradual slowdown, while global
keybinds wait for Accessibility permission.
#13590
GTK: Splits can now be rearranged with drag and drop, matching macOS.
Drag a split by its handle and drop it onto another split, including
splits in other tabs and windows.
#10224
#10423
GTK: Ghostty now renders at the true fractional scale (e.g. 125% or
150%), so text and box-drawing characters are sharp instead of blurry
under fractional scaling.
#1938
#14269
GTK: The renderer no longer uses
GtkGLArea
. Ghostty now renders with
EGL entirely on the render thread and hands finished frames to GTK as
DMABUFs, so the main thread no longer does any OpenGL work.
#14052
#14636
GTK: Windows can now be renamed using the menu, command palette, or the
new
prompt_window_title
and
set_window_title
binding actions.
#10469
#10999
GTK: A new
+new-tab
CLI command opens a new tab in a running Ghostty
instance. When run from inside Ghostty, the tab opens in the same
window. It accepts the same
-e
,
--working-directory
, and
--title
flags as
+new-window
.
#11762
GTK: A new
+toggle-quick-terminal
CLI command toggles the quick
terminal of a running Ghostty instance, useful for binding in window
managers without global shortcut support.
#12661
GTK: Global keybinds now use the
vicinae-hotkey-v1
Wayland protocol
when the compositor supports it (e.g. Hyprland 0.56+), falling back to
the XDG desktop portal otherwise. Ghostty shows a desktop notification if
a global keybind can't be registered.
#13464
GTK:
quick-terminal-screen
is now supported on Wayland. The default,
main
, places the quick terminal on the compositor's primary output
(or the first monitor if the compositor doesn't report one). Set it to
mouse
to let the compositor choose, which was the previous behavior.
#11117
GTK: On Wayland,
background-blur
now uses the compositor-agnostic
ext-background-effect-v1
protocol instead of KDE's blur protocol,
enabling blur on compositors such as Niri. The blur region also no longer
covers the window's client-side shadows.
#10721
#10720
#10727
GTK: On GTK 4.23.3 and newer,
background-blur
uses GTK's built-in
background blur, which covers the window more accurately.
#13581
#13586
GTK: The
open_config
binding action now accepts
new_window
to
edit the configuration in
$VISUAL
or
$EDITOR
in a new Ghostty
window. The default,
os_open
, keeps the previous behavior.
#11905
GTK: A new configuration
gtk-horizontal-tab-scroll
(default
true
)
can be set to
false
to stop two-finger horizontal scrolling from
switching tabs, passing the scroll to the terminal application instead.
#12659
GTK: A new configuration
gtk-tabs-inverted
moves the close button to
the start of each tab, in both the tab bar and the tab overview.
#14657
GTK: The default command palette entries are now translatable.
#11641
GTK: The embedded Noto emoji fonts were updated, so newer emoji and ZWJ
sequences such as the head-shaking faces render as one glyph instead of
overlapping neighboring cells.
#14047
GTK:
ctrl+shift+page_up
and
ctrl+shift+page_down
now move the current
tab left and right (
move_tab
), matching Firefox, GNOME Terminal, and
VS Code.
jump_to_prompt
moved to
ctrl+shift+arrow_up
and
ctrl+shift+arrow_down
.
#4998
#12458
GTK: URLs now open through the XDG desktop portal, falling back to
xdg-open
if the portal is unavailable. Ghostty passes an activation
token so the opened application, such as your browser, can come to the
front on compositors that require one.
#5991
#11754
#14785
#14787
GTK: Desktop notifications are now withdrawn when their terminal is
focused or closed, and repeated notifications with the same text
replace each other, matching macOS.
#14108
GTK: Tabs that aren't visible no longer render, saving CPU and GPU.
This matches macOS.
#12760
GTK: The Dolphin "Open Ghostty Here" action now opens a new window in
the running Ghostty instance instead of launching a separate one.
#11614
GTK: Fix Ghostty sometimes failing to launch with systemd 262, which
refused to start the service because Ghostty reported readiness before
it could handle reload signals.
#14398
#14399
GTK: Fix deeply nested splits sometimes becoming invisible or losing
focus.
#11193
#12698
GTK: Resizing splits, especially with
resize_split
keybinds, no
longer flickers.
#13414
GTK:
resize_split
on nested splits no longer causes large jumps in
size.
#12699
GTK: Splits can no longer be resized smaller than one cell, by dragging
the divider or with
resize_split
.
#14476
GTK: High-resolution scroll wheels no longer scroll much faster than
standard scroll wheels.
#12483
GTK: Disable unwanted kinetic scrolling on trackpads with GTK versions
older than 4.20.1.
#11793
GTK: Middle clicks are once again sent to terminal applications using
mouse reporting when
gtk-enable-primary-paste
is disabled in
GSettings.
#12940
#13108
GTK: The quick terminal no longer breaks when toggled off manually
while
quick-terminal-autohide
is enabled.
#11679
#12471
GTK: Opening the right-click context menu no longer hides the quick
terminal when
quick-terminal-autohide
is enabled.
#12843
GTK: The resize overlay no longer keeps reappearing when the scrollbar
is visible and no longer blocks mouse input while shown.
#11970
#11972
GTK: The maximum window size is now based on the monitor the window is
currently on, not the monitor it was opened on.
#13171
GTK:
+new-window -e
now works when
shell-integration
is set to a
specific shell.
+new-window
and
+new-tab
also accept a new
--shell-integration
flag.
#12378
#13741
GTK: Keys remapped to modifiers with XKB (e.g. Delete remapped to
ISO_Level3_Shift
) no longer also send the original key.
#13967
GTK: On Wayland, the IME candidate window now follows the cursor while
composing and no longer covers the line being edited.
#14729
GTK: Splits in a tab that was moved to another window now act on the
new window (e.g.
toggle_fullscreen
).
#14474
GTK: The mouse cursor keeps its text shape while selecting text.
#14558
GTK: The command palette now uses the terminal colors when
window-theme = ghostty
.
#14662
GTK: Opening URLs no longer fails when the fallback opener (
xdg-open
)
produces large output.
#12797
GTK: Clicking a desktop notification no longer focuses the wrong
terminal when the one that sent it has since been closed.
#12028
GTK: A bell in the focused terminal no longer leaves the bell
indicator set.
#13597
GTK: Fix the window continuously redrawing in the background after an
indeterminate progress bar (OSC 9;4) was removed.
#14704
#14738
GTK: Fix a crash when closing tabs or splits on GTK 4.20 (GNOME 49).
#12426
GTK: Fix a crash with global keybinds or on configuration reload when
no D-Bus connection is available.
#13101
GTK: Fix a possible crash when Fontconfig reports a font's language as a
plain string instead of a language set.
#14853
GTK: Fix a leak where every audio bell started a new GStreamer pipeline
and threads that were never cleaned up, slowly raising CPU usage.
#13647
#12815
#13657
Snap: Link the system FreeType, Fontconfig, HarfBuzz, libpng, and zlib
instead of bundled copies, fixing frequent crashes caused by two copies
of the same library in one process.
#14392
#14682
Snap: The snap's own GIO modules and XDG data directories now take
priority over the host's.
#12045
Snap: Programs running inside Ghostty, such as
clear
, now find the
xterm-ghostty
terminfo entry.
#12662
Flatpak: Commands started by Ghostty on the host are now terminated if
Ghostty crashes.
#12427
Ghostty 1.4 introduces full localization for the command palette and adds
support for
4 new languages
:
Basque
Belarusian
Danish
Serbian (Cyrillic and Latin scripts)
Localization is maintained by volunteer contributors. If you want to
help localize Ghostty in your language, please open a discussion on the
GitHub repo. Thank you to all the volunteers who contributed to Ghostty's
localization!
GTK builds now require
GTK 4.18
and
libadwaita 1.7
, up from
GTK 4.14 and libadwaita 1.5. Builds against older headers fail at
compile time, and Ghostty exits at startup if older libraries are
loaded at runtime.
#14330
GTK builds now link the system EGL library (pkg-config
egl
, usually
provided by libglvnd or Mesa) for the new renderer. At runtime, Ghostty
uses GTK's EGL display when it can, and otherwise needs an EGL driver
that supports the surfaceless platform.
#14052
#14636
A new
-Dinstalled-exe-path
build option sets the absolute executable
path written into the desktop file, D-Bus services, and systemd user
service. Previously this path came from the install prefix. Without the
option, these files now name
ghostty
alone, which systemd only finds in
/usr/bin
or
/usr/local/bin
, so set it for any other prefix.
#14805
#14806
When linking the system gtk4-layer-shell (
-fsys=gtk4-layer-shell
),
version 1.0.4 or newer is now required. Ghostty no longer disables the
quick terminal on older versions, which can crash on some compositors.
#11559
As with 1.3, libghostty isn't directly part of the Ghostty 1.4 release.
But a large part of the 1.4 development cycle went into libghostty, so
here's an update.
Over the past 6 months, the C API for libghostty-vt has grown from a
parser and a few encoders into a complete terminal emulator API, adopted
by dozens of free and commercial terminal emulators used by millions of
people. It's hard to quantify exactly, but the number of people using a
libghostty-based terminal is confidently several times the number of
people using the Ghostty GUI.
libghostty-vt now builds for macOS, Linux, Windows (MSVC and GNU), FreeBSD,
Android, iOS, and WebAssembly, and CI continuously verifies every one of
these targets. The goal is for libghostty-vt to be generally usable everywhere,
within reason, so if you want more target support, let us know!
It's also easier to integrate libghostty-vt into existing build systems.
There's CMake support, Nix packaging, an xcframework, and a source
tarball, in addition to the existing pkg-config file.
libghostty-vt no
longer needs libc++, and it can build freestanding.
The API is still marked as a work in progress and broke compatibility
several times during this cycle, so expect more breaking changes before
a tagged release. The
API documentation
and the
Zig, C, C++, Swift, and WebAssembly examples
(now over 30) are kept up to date with
main
.
We're going to do a final pass over the C API, break ABI one more time,
and then likely tag a libghostty 1.0 release very soon.
During the 1.4 cycle, we paid
$41,820
to contributors under contract and
spent about
$1,260
on infrastructure such as website hosting.
I'm happy to share that we've now signed our first two
12-month contracts
,
which give contributors stable, long-term paid work on Ghostty and help
ensure the ongoing stability and sustainability of the project:
@trag1c
is Ghostty's head of operations.
He manages the community on GitHub and Discord, coordinates our
volunteer translators, and maintains various other important project
systems.
@vancluever
works on various Ghostty
subsystems. In this cycle, he led the upgrade to Zig 0.16, moved the
build off Zig's deprecated
@cImport
, updated the bundled Fontconfig,
and more. He's also the author of
z2d
, the 2D graphics library Ghostty
uses to draw box-drawing characters and other sprite glyphs.
The primary focus of the roadmap continues to be libghostty functionality,
stability, and portability. During the last release cycle, I said I aimed to
tag a libghostty release. We haven't done that yet, but I'm confident we will
do so before Ghostty 1.5.
libghostty is a project that continues to be the tide that lifts all boats.
libghostty improvements tie directly to Ghostty GUI improvements as well as
dozens of other large projects in the ecosystem. As more large projects adopt
libghostty, libghostty tends to get more testing and attention, and this
creates a cycle that yields the most gain for terminal emulators everywhere.
macOS and GTK builds of Ghostty have talented, capable maintainer teams that
are continuing to improve them, so they're not neglected by any means!
As a project, we've decided to drop any roadmap for Windows support in the
Ghostty GUI. libghostty fully supports Windows (and we test it in CI), and the
official stance now is that downstream projects should use that.
Our release cycle remains 6 months. This release was delayed by one month,
but Ghostty 1.5 is planned for March 2027. libghostty will have a separate
release cycle.
