sudo-rs might become the default in future Ubuntu releases!

The details from Ubuntu VP of Engineering Jon Seager: discourse.ubuntu.com/t/careful

Our team, Marc, Bjorn, Ruben and Marlon are core contributors of sudo-rs, which is now part of Trifecta Tech Foundation, the non-profit backed by Tweede golf and the long-term home for open infrastructure projects such as sudo-rs, zlib-rs and Pendulum.

Ubuntu Community Hub · Carefully But Purposefully Oxidising UbuntuYou’re switching from a GPL licensed core utils to an MIT licensed core utils. I cannot support this decision. If this goes through, I will migrate all servers and workstations that I admin to Fedora/Rocky. The GPL ensures that contributions to essential utilities remain accessible to all, preventing proprietary forks that benefit corporations while sidelining the community. Unlike the MIT license, which allows unrestricted appropriation, the GPL guarantees reciprocity: if an entity benefits f...

@atoponce holymoly, i just had a look at github.com/uutils/coreutils/bl

this thing has 419 dependencies! maybe irrelevant mem-safety benefits are not in balance with the consequences of this kind of supply-chain attack surface? maybe we should have a talk about this?

We pushed out a beta a couple of months ago, but we finally sorted the full release!

It should be in your favourite package manager reasonably soon.

GitHubRelease fish 4.0.0 (released February 27, 2025) · fish-shell/fish-shellfish’s core code has been ported from C++ to Rust (#9512). This means a large change in dependencies and how to build fish. However, there should be no direct impact on users. Packagers should see ...

step 1: Oh no, this numerical optimization written in #Python is too slow.

step 2: Let's #RiiR!

step 3: I bet #argminrs will be really fast!!

step 4: Ok, that's faster than Python, but I expected more. What will it be? Is heap allocation the bottleneck? Will I need to switch to a more efficient HashMap implementation? Cache some intermediate values?

step 5: Let's profile!

It still shocks me that no one has #RIIR the homebrew yet. The slowest package/dependency manager/tool these days (no parallel casks downloading, no multi-threads downloading, and no parallel attestation verification).

@hds Nice, thank you for sharing! ❤️

Regarding "better auto-vectorization when reslicing":

This is also mentioned in this in-depth article about Prossimo's work on #RiiR an AV1 decoder.

See this section on bounds checks specifically:

memorysafety.org/blog/rav1d-pe

Super interesting stuff! 🤓

www.memorysafety.org · Optimizing rav1d, an AV1 Decoder in RustAV1 is an increasingly important video format and it needs a memory safe, high performance decoder. We worked with the team at Immunant to develop rav1d. Performance is critical in this context, so we've asked Stephen Crane, CTO of Immunant, to explain their efforts in achieving performance parity. If you'd like to dig deeper, check out our recent blog post about how we ported the C AV1 decoder to Rust.

@tirifto@jam.xwx.moe "100K lines of C++" is very misleading btw, as that figure contains the encoder, benchmarking tools, and other optional parts. The decoder, which is what Firefox only needs, is way smaller.

So yeah before I was like "that's some #RIIR bullshit but better than nothing I guess", but now I'm not more optimistic. They're just finding another excuse to not support #JPEGXL after #Safari leapfrogged them ​:seija_coffee:​

NitterJon Sneyers 🟣 (@jonsneyers)That count includes the encoder, jpeg bitstream reconstruction, jpegli, various tools like metrics, benchmarking tools, hdr conversion tools, etc. Just the decoder alone is way smaller.
