Well, with just hours to go, my self-imposed deadline to launch the RC2014 Zed Mini has been accomplished!

Now live on z80kits (shipping from Thursday), along with technical details and assembly guide on the #RC2014 website

https://z80kits.com/shop/rc2014-zed-mini/

I'm really pleased with how this kit turned out. There's such a lot crammed in to the Mini form factor, and with a 5 slot backplane on top it can be a real powerhouse!

New funnel just dropped.

@elonjet this was a 44 minute flight

It's the weekend, somehow.

Anyone working on fun projects?

I have fresh polymers, a pile of aluminium extrusion, and a fistful of vague ideas.

⏰ One day to go! Thinking about proposing a talk but kind of forgot? Don't worry, you have until Sunday 22:00 UTC to write and submit an abstract. It can be brief!

🇪🇺 LSS-EU 2026 is co-located with @linuxplumbersconf 🏰 ; the day after LPC. There should be a good critical mass of both Linux OS _and_ Linux security developers 🛠 across these events, which is not always the case.

📢 Linux Security Summit updates:

🐧 Videos from LSS-NA 2026 are up: https://youtu.be/IUjfjWSNj2k?si=WSMQhDAo_UISxqcO

🐧 The CfP for LSS-EU, co-located with OSS-EU and Linux Plumbers in Prague, closes soon: June 28th. https://events.linuxfoundation.org/linux-security-summit-europe/program/cfp/

Some weekend progress on my quick* Pi5 radio terminal project. I've since added a GPS HAT, to provide accurate time for digital modes & real-time grid determination.

* About a week, +/- six weeks.

@jarkko nice!

Apparently one can just claim to have codesigned any scheme now, so let it be known that Julius and I coauthored the Caesar cipher

I think 6m is open.

Radio folk: here's something I just learned. Sporadic E propagation sometimes opens up at night. Noticed some reports from AZ last night around 11PM for my 50 MHz FT8 test transmissions. Turns out this is or was an interesting research area.

Would you like to be part of citizen science astronomy? We invite you to classify gravitational lens candidates in so-far unreleased #ESAEuclid data: "Space Warps – ESA Euclid DR1".

3000 volunteers have already made nearly 900,000 classifications, yet 70% of the project are still to be done.

2️⃣ Here's the 2nd post highlighting key new features of the upcoming v261 release of systemd. #systemd261 #systemd

When you care for a more than a single system, it is often advisable to roll out new stuff in a staged fashion: first 1% of your fleet should get it, and only after the results are in and all is good, you up it to 10%, and then to 25% and finally to 100% (or in other steps like this).

With v261, systemd is going to help you with this to some degree:

Very pleasantly surprised to discover the Voron Design open source 3D printer community in recent weeks. I'd heard the name but didn't know much about it, especially the size & broad scope of things.

So many experiments & side quests, not just in 3DP, but across all kinds of CNC, kinematics, embedded hw, & of course, software hacking.

There's also a network of very cool small businesses supporting all this with kits, components, innovations etc.

Trying to avoid starting yet another project of the venerable "crazy but not actually impossible" class.

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…
