It's that time again! The systemd v261 release is coming closer. Let's restart the "what's new" series of posts for this iteration! Hence:

1️⃣ Here's the 1st post highlighting key new features of the upcoming v261 release of systemd.

systemd-repart is systemd's dynamic disk partitioner and image generation tool. It only deals with GPT disk labels – or more precisely, it only dealt with GPT disk labels *so* *far*. With v261 there's…

Linux Security Summit 🐧

Edited 7 days ago
A reminder that LSS-NA is happening a week from now in Minneapolis, MN!

Note that we have had three speakers withdraw due to circumstances beyond their control. We hope they are able to present their work at future community events, including LSS, where possible.

We've now added a Hackathon session on Day 2 (Friday May 22), where folk can work together in person on solving Linux OS security challenges of their choice. This could be for brainstorming, high-level design, PoC development, bugfixing etc. Utilization of generative AI is welcome.

As always, we will also have BoF sessions. Folk may also use these to make brief lightning style talks as appropriate, which may be useful for pitching new ideas or highlighting issues to the Linux OS security community. We've seen this work well over the past few LSS events.

🐧 See the current schedule here: https://events.linuxfoundation.org/linux-security-summit-north-america/program/schedule/

p.s. There are rumors of new LSS stickers being made available at the conference.

@alexglow Understood. I found it oddly comforting, somehow. It's difficult to explain without major spoilers, but the show is a masterclass in design. Color is deeply integral, and they even spell the mapping out explicitly if you watch closely enough. I'll provide a link to a tiktok (sorry) video which has a good summary. Some of the other resources on the topic are close but missed the precise meanings as revealed via easter eggs, hidden in plain view. What I love about it there is nothing superfluous or accidental anywhere. Every scene, color, word, or object, is part of a coherent world. And it's a strange one, which makes it interesting. Our real-world dystopia is chaotic and boring, alas. Spoilers within: https://www.tiktok.com/@jbuckstudios/video/7446841285513596190

@alexglow have you seen Severance? There’s some interesting color coding in that, which someone dug up.

@ExtKits do you have any for sale? A matte 18% gray version would be nice for making reasonably accurate photos.

Doing a bit of a deep dive into 3D printing engineering filaments this weekend. Nylon + CF is a great all-rounder, it seems. Perhaps like how 6061 Aluminium is for metal fabrication.

@ExtKits what material are those walls? Looks like a good idea for project photos.

Cool!

I've just been accepted to do a Build a lightning detector workshop at

I'll drag @Extelec to help out, of course :)
