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. #systemd261 #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…

It's the weekend, finally.

What are you all working on, or doing, or not doing?

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.

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

Are we heading towards Extinction Level Enshittification?

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.

Cool!

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

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

Shout out to the “roll over to zoom in 🔎” enthusiasts. bless your hearts.

Playing with a Raspberry Pi 5, 4MB RAM. It’s been a few years since I looked at the Pi — my old one is a v2. These have come a very long way.

Reorganizing my home office & added a new switch to provide PoE and SFP. The latter is for steaming I/Q samples from mast-mounted SDRs for local processing. POE is for desktop IP phone (SPA525G) & SBC hacking.

Quite happy with this low-cost Linksys so far. 1990s me with a 10BASE2 net connected to a dial up modem would be astonished.

For those of you that submit content to Linux Plumbers, you will be able to buy tickets for the conference two weeks before it opens. And if your content gets you a free pass, yes, you will be refunded.

@ada Just struck me that this is the first photo I've seen of a woman beyond Earth's orbit.

RE: https://zoner.work/notes/akpflj8w7ccm000g

the artemis 2 photos go extremely hard

Experimenting with 3D printed DIN rail mounts for projects. The attachment brackets are from open source hw projects, as are the WAGO & RS25 brackets. The PCB & vertical mount brackets are customized (to be published soon). I’ll adopt some kind of hole pattern standard for my own PCBs to simplify things. Possibly 20x20mm grid?

Transequatorial propagation (TEP) on 6m is strong today. It follows Earth's magnetic field lines for certain distances across the equator for complex reasons, allowing N/S America or JPN/AUS communication on VHF at times.

Good morning.
