8️⃣ Here's the 8th post highlighting key new features of the upcoming v257 release of systemd.

A longer time ago systemd introduced JSON based user records as an extension of classic UNIX `struct passwd`. These records can be provided via Varlink IPC or via drop-in files. The much richer set of account settings is documented here:

At Linux' best conference, All Systems Go! 2024 in Berlin this year I gave a (brief) talk about Varlink, and why you should consider it. If you want to know more about the concept, this might be a good starting point:

And that's all for now, enjoy!

Had fun in at in Tokyo yesterday demonstrating a TPM interposer attack obtaining the systemd cryptenroll boot keys

https://sched.co/1jKCe

And also explaining how the new Linux Kernel TPM patches can help defeat this

For those who asked, my python3 interposer designed to steal the keys is here:

Adding uchar.h to picolibc today. Instead of providing useful conversions between UTF-8, UTF-16 and UTF-32, all C23 provides is conversions between those and the awful "multibyte" representations. I can understand why they'd *also* want to connect UTF encodings to the legacy C APIs, but the most important thing we need is a way to validate UTF-8 input which has some pretty tricky corner cases involving missing bytes, overlong encodings, and surrogates. https://github.com/picolibc/picolibc/pull/861

10 GHz beacon testing around Seattle on the weekend. Frank AG6QV (https://ag6qv.com/Blog/uhrc) was able to receive via reflection from Puget Sound ferries. Now thinking about a proper mobile-mounted setup for quick 2-way contacts.

This is bonkers for 6m. It's at the low end of the old VHF analog television channels (#2 in many places).
