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?

Your (or your employer's) financial support for the PSF would be very much appreciated this year! (And every other year too) bsky.app/profile/pyth...
In the end, it wasn’t a hard decision for the PSF to put our community and our values first, but it does mean we lost out on this large funding source. Donations and sponsorships will help us fill the gap, so we can continue supporting the Python ecosystem and living our values.

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.

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/...

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 :)

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...

I wondered how `From` 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.
