"The GNU libc atanh is correctly rounded." (https://inria.hal.science/hal-05591661) That simple phrase is so exceedingly hard to prove, and yet we chase the goal because some workloads require it and we can achieve this goal in some cases without worst case performance loss. For glibc 2.43 the project has integrated 32 of the CORE-MATH library functions.

It looks like Dutch government will avoid the unbearable dumbness of lowering fuel taxes amid a supply crisis! More sensible measures include compensating kilometers driven for work, support for low income households, and more subsidies for insulating homes.

We’re happy to share that Mastodon has been awarded a service agreement from the Sovereign Tech Fund @sovtechfund 🎉

This covers five major initiatives through 2026 and 2027. We are very grateful for this support. Read about the details in our blog post.

I don't want to drink alone, but I do enjoy a "post work drink". So I buy alcohol free beers for those occasions. Tried this IPA today, and I really like it!
Definitely will pick up a crate next time.

I wrote a blog post about how smtgcc, my GCC translation validator, handles uninitialized memory.

#gentoo #portage feature I learned about today by accident:

emerge --pretend --fetchonly (shortened as emerge -pf) will print all the URLs it'd use to download the various distfiles, instead of listing the results of the dependency resolution (as --pretend would usually do).

Caught me off-guard, I don't think this is documented anywhere. Glad to know portage still hits me with surprises after using it for 7 years 😅

Positive News: France has announced its plan to ditch Windows & switch to Linux for government desktops. 🥳 🇫🇷

Not only that, but they have also moved 80, 000 National Health Insurance Fund Employees to open source alternatives replacing U.S owned Big Tech platforms like Microsoft Teams & Zoom.

It’s amazing to see the country take action, push for real digital sovereignty, & opt for open source solutions! 👏

@gsuberland @whitequark at my first job I had to get PHP running on a network card

Two papers came out last week that suggest classical asymmetric cryptography might indeed be broken by quantum computers in just a few years.

That means we need to ship post-quantum crypto now, with the tools we have: ML-KEM and ML-DSA. I didn't think PQ auth was so urgent until recently.

The schedule of the upcoming "Embedded Recipes" conference (May 27-28, Nice, France) is available. A fine selection of topics and speakers!

I hope to see many of you there, and don't forget the Yocto day on May 29, which schedule is expected in 4 days (Apr. 10).

@never_released still not really a mainframe guy, but IIUC they're not really about CPU performance and they haven't really been all that compelling at that in a long time.

I'm always a bit lost when trying to read through the IBM manuals, but looks like they still have a bigger single shared memory domain that Intel or AMD -- 64TiB on the IBM stuff, 32TiB on Intel and 12TiB on AMD. They're also got some crazy-sounding cache sizes (36MiB private L2, for example), and I think that's part of how the handle their huge systems (though the other systems seem to be catching up there, too).

I've also really never understood their I/O architecture, but IIUC they push a lot of stuff that PC-derived systems would do on the CPU into the I/O subsystem's co-processors and that's part of the mainframe magic -- though with modern I/O stuff I'm not sure how true that is any more, the high-performance stuff is pretty hands-off from the CPU side of things and has a decent amount of compute living on the other end of PCIe.

@never_released I'm not a mainframe guy, but IIUC a lot of what would go over the network on PC-derived servers goes over the interconnect on mainframes. So the network side of things there is really only for the traffic that needs to cross the boundary between the mainframe world and the regular world.

Big thumbs up to our first 2026 supporters: HAProxy, @igalia , ARM, Jump Trading.

Want to be part of it too? We’d love to have you on board. Your support is what makes it possible to keep a high-quality 3-day conference affordable and to share the content with a wider audience.

Join us!

• Claude code source "leaks" in a mapfile
• people immediately use the code laundering machines to code launder the code laundering frontend
• now many dubious open source-ish knockoffs in python and rust being derived directly from the source

What's anthropic going to do, sue them? Insist in court that LLM recreating copyrighted code is a violation of copyright???

@wingo I would read a blog about _that_ process.

I Decompiled the White House's New App https://blog.thereallo.dev/blog/decompiling-the-white-house-app
The official White House Android app has a cookie/paywall bypass injector, tracks your GPS every 4.5 minutes, and loads JavaScript from some guy's GitHub Pages.

We can remove strncpy() from the Linux kernel finally! I did the last 6 instances, and dropped all the implementations:
https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/log/?h=dev/v7.0-rc2/strncpy

Over the last 6 years working on this, there were 362 commits by 70 contributors. The folks with more than 1 commit were:

Thank you to all of you! (And especially to Justin Stitt who took on the brunt of the work.)

We were just notified today that one of our teammates is going to be let go.

We've been working together for over 3 years, and he's been a great teammate.

I don't know his full skill set, but we're a Ruby shop, and I know he's got some PHP experience under his belt as well.

If you know of any open positions for a senior role in Ruby or PHP, let me know.

Plz boost.
