Just published this entry-level tutorial for agentic development via a CLI, also covering internationalization and accessibility.

https://github.com/xjamesmorris/lockedin-cli

If you don't know where to start, try this, at the command line with one of the CLI tools.

Made this shrinkage model for FDM filament calibration, which is designed to work well with 150mm digital calipers.

It's almost midnight, I wonder if who's on 6 metres? The entire population of Japan, it seems.

Congrats also to Fabio Valentini, the third winner, who we hope to have on a future episode!

Do you have a Skådis board, a specific make and model of electric screwdriver, and a 3D printer? If so, this is your lucky day.

Inching closer to an initial release of this project (RF Deck). Incorporating changes after some field testing a couple of weeks ago.

The onboard GPS antenna is an issue, it’s pointed out the back of the device, which will often mean it’s pointed down at an angle. Flipping it over means it will look directly at the metal case of the touchscreen. Best option is a smaller GPS board which can point up, or a separate embedded antenna. For now I am using an external GPS antenna which can be magnetically attached to the top of the enclosure (see embedded magnet near fan).

Do you like wireless radio CTFs? Interested in learning more about DSP, FPGAs, and FFTs?

Here's a CTF based on a real lunar mission that introduces the concepts in a fun and friendly way.

RC2014

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 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!

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.

Linux Security Summit 🐧

⏰ 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!

🐧 https://events.linuxfoundation.org/linux-security-summit-europe/program/cfp/

🇪🇺 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.
