@bagder I thought you said “exhausting nothingness” for a moment and I think that also fits generally.

picolibc has been reformatted with clang-format. All PRs will now be checked to make sure they are formatted correctly, so any pending requests will need to be fixed and resubmitted. I'm looking forward to having only one coding style to deal with.

Thanks to all of the picolibc contributors over 2025 and best wishes for 2026.

Right on time to coincide with the end of the year I finished my series of posts. And I now also prepped a blog story linking to every single one of them here:

https://0pointer.net/blog/mastodon-stories-for-systemd-v259.html

Make sure to stay tuned for the series, most likely starting already in a few weeks!

Also, happy new year! 🎇

@david_chisnall @SecurityWriter I skipped a couple of years and watched the last episode. Glad I didn’t waste any more time on it.

@kkarhan @etchedpixels @landley @ghul @jti42 @pkal governments, too. Secure versions of Unix were generally awful in every respect.

A few weeks ago, Michelle @abraxas3d visited us. She wrote a very nice report on "A day at Dwingeloo", detailing some of our recent experiments. The full story is at https://www.openresearch.institute/2025/11/12/a-day-at-dwingeloo/

Idle thought: I’ve been working as an IC for a few months again after many years of management. I fundamentally enjoy the development work and open space on my calendar. Digging deeply into some new technical area and solving a difficult problem with few distractions is very much my thing and does not feel like work at all. But with this also is the realization that I can accomplish at least 10x of that by helping a team to solve some larger scale problem—moving the needle in a meaningful way, which also means delivering that to people.

1️⃣5️⃣ Here's the 15th post highlighting key new features of the recently released v259 release of systemd.

Here's a quick one: you might have noticed that whenever a systemd service deactivates we'll log a brief journal message saying the amount of CPU time consumed, and the peak memory used by this unit cycle. With v259 that message is slightly extended: it will now also indicate the wall clock time passed since activation of the unit. This is particularly nice when…

Regularly asking yourself "What if everything I know is wrong?" is important.

Reply to @alison@burningboard.net
@alison @yoctoproject @linuxplumbersconf the idea is that we want to use the container boundary as a well defined security abstraction, and then we can simplify the design of the system overall, i.e., the base system is essentially fixed, and there is a well defined “app model” at the container boundary. The type of container actually implemented is not specified — it can be a systemd portable service, for example. It would be possible to not use a standard container runtime, and build/use some lightweight name spacing scheme. We do want to avoid workloads which install directly and do whatever they want all over the system, as it is infeasible to secure at scale in a broadly adoptable manner.
