I created a feedback issue asking what people are using Ocrs for - github.com/robertknight.... I was originally expecting it would mostly be document scans and photos, but a lot of usage seems to be related to parsing screenshots.

I always feel bad for people who spend a ton of time on a pull request that the project doesn’t want. You can avoid wasting a lot of time by first opening an issue describing what you’re thinking of doing to get feedback before you start coding.

I was trying to explain what I'm working on to a relative. I resorted to my favorite XKCD comic - xkcd.com/1838/.

I think my favorite use of Claude is just being able to type "fix the merge conflicts" and letting it deal with them.

Today's edition of malware on npm involves the official PostHog JS packages: news.ycombinator.com/item?id=4603...

Don't ask a woman her age, a man his salary, or an ML engineer how his kernel handles NaNs and infinities.

"Translate from Gen Z to millenial" has been an unexpected use case I've had for AI.

I created a proof-of-concept showing how to convert ML inference in Google's Magika file type detector from C++ (via ONNX Runtime) to Rust using RTen - github.com/google/magik...

I'm working on getting Q4-quantized Llama 3 working at reasonable speed in RTen (ie. competitive with llama.cpp and ONNX Runtime on x86/Arm). Given the pace of change I'm tempted to describe this as retro computing in the release changelog.

Does the "Show fewer shorts" button on YouTube actually do anything or is it like the "push to wait" button at pedestrian crossings?

recently discovered that wikipedia volunteers have a hilariously high bar for what constitutes "unusual death"

I currently have availability for Rust coaching, adoption, or development; from a single call to ongoing 3 days/week. I can help your team get things done, adopt Rust and use it more effectively, or to accurately evaluate Rust as a new technology.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most. So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion. interop-rank.jakearchibald.com

RTen v0.23 has been released! (github.com/robertknight...) The big new thing is that it can load ONNX models directly without requiring conversion to the custom `.rten` format. This makes it easier to switch between RTen and another machine learning runtime, or use it alongside another runtime.

Does widespread browser implementation of the Sec-Fetch-Site HTTP header mean we can protect against CSRF attacks without needing those hidden form tokens? It looks like the answer may be a cautious "yes"! simonwillison.net/2025/Oct/15/...

We’re hiring for two machine learning roles. A chance to do cutting edge things with ML to make this place a lot more personalized. jobs.gem.com/bluesky/am9i...

The crates.​io team was notified of two malicious crates (with similar names as legitimate crates) which were actively searching file contents for Etherum private keys, Solana private keys, and arbitrary byte arrays for exfiltration. See the blog post for details: blog.rust-lang.org/2025/09/24/c...

In case anyone is using Alacritty and encountered poor performance or crashes after updating to macOS Tahoe, the issue is resolved on the `master` branch. I took this as an opportunity to try ghostty.org in the meantime. What a great logo :)

Reddit has been recommending me posts from /r/linguisticshumor lately, and I think I'm being out-nerded. This is a most unusual experience.

The Lean version of Rust's `todo!` macro is called `sorry`. This is clearly a much better name.

RTen v0.22 has been released. The main new feature is support for `Loop` and `Sequence*` operators in ONNX models. There are examples for Kokoro and RT-DETR. Also many activations, reduction ops and trig functions were vectorized for much better performance - github.com/robertknight...

some thoughts about the bloat introduced by edge-case first libraries

Have just come out of a cafe where toilets are segregated by whether users are left or right handed. I appreciate the novelty.

Google AI doesn't know my IP, but kindly hallucinates one.

I've been doing some work pruning RTen's binary size. Some surprising offenders. github.com/dtolnay/carg... is a super useful tool for this.

Uber horse

I wondered how `From<Infallible>` is implemented in Rust. How do you define a conversion from a value that cannot exist? The answer is with an empty `match` - doc.rust-lang.org/src/core/num....

Zeroing memory can be much faster than filling it with an arbitrary value, as there are special hardware instructions for it on eg. Arm - developer.arm.com/documentatio.... If you have to fill a large block of memory with a user-provided value, it can be worth special-casing for zero.

My experience of GPT-5 has been positive. The more neutral tone of its responses suits me (I don't like unnecessary emotion in conversations), and having it auto-select the amount of reasoning to use seems to work well.

⚛️📝 New on Overreacted: Beyond Booleans

Rust v1.89 finally brings AVX-512 support to stable, which means the next release of RTen will enable it by default.

What tools/services do my followers use for security scanning of open source Python and npm dependencies? Would you recommend them?

Why yes, I am a senior Mustache engineer with over 10 years experience.

When I'm noodling on a slightly tricky problem, and I ask ChatGPT for some ideas, it is mildly reassuring if getting a useful answer requires using the highest tier model and a lot of thinking time.

ARIA live regions are an absurd API for delivering accessible notification messages (they do make sense for other use cases). I am glad to see work on a better alternative - groups.google.com/a/chromium.o...

I'm investigating using Arm's i8mm extension for int8 matmul in RTen. This appears to be much faster (~1.6x) than dot product instructions on Neoverse cores (eg. AWS Graviton) but not Apple Silicon. This is perhaps not surprising but I haven't found this documented anywhere.

I used to think of "sum types done right in mainstream languages" as a relatively recent thing. The history goes back further than I thought - graydon2.dreamwidth.org/318788.html

Cow-lories

Donkey Kong Bananza being a modest 8.6GB download feels like an homage to Super Mario 64's tiny cartridge size (8MB).

I can confirm this is exactly as intuitive as I expected.

If Claude runs into a difficulty on a task, it loves to declare victory and move on: "Task complete ✅, everything is done 🚀. Some tests couldn't be run because they depend on a database which isn't running, but I'm sure they are not important"

Scope hoisting is broken in most JavaScript bundlers, and I'm considering removing it in Parcel v3. Wrote a post about why. devongovett.me/blog/scope-h...

Howdy all. I'm unfortunately not going to be with my employer for much longer due to team relocation. If anyone has any info on roles that would allow me to continue my Rust compiler work (in New York City), they'd be greatly appreciated.

Do any followers have recommendations for brands of small form-factor PCs that are good for Linux development? I'm looking for something Mac Mini-esque that I can get with a Zen 5.
