Oh, damn.
And they thought _you_ were Arduino. Amazing.
I don't believe them.
Exactly what an AI would write ;-)
New blog post: Remote diagnosing a PET 2001 video fault from one photograph.
blog.tynemouthsoftware.co.uk/2026/02/diag...
Includes a look at how the PET video system works with redrawn schematics.
It also turns out to be a surprisingly early PET 2001.
And NASA confirms it, WDR-2 now this Thursday, T0 at 20:30 EST, (01:30 UTC on Friday

#ArtemisII
Working on an S-band helical feed for Artemis II and other spacecraft. This is a 4-turn helix for an offset dish, per the W1GHZ antenna handbook.

Introducing the new ko4fzg.com, where I've uploaded all my manuals and ham radio manuals. It's just the basic easy to find ones for now so the utility is limited but I'm adding more interesting ones.

Background noises locally or in your transmitted RF? Very nice looking piece of hardware. I wonder how it compares with something like the IC7300.

I gave a talk at #FOSDEM about Island: Sandboxing tool powered by #Landlock

Is this from the youtube video feed?
Close up of the resonance igniter built by The Exploration Company in Bordeaux, France. A close-up view of a precision laboratory setup shows a pair of gloved hands working on a small metallic component connected to a larger stainless‑steel assembly.
Building a working rocket engine is one thing.
But igniting the engine in a stable and repeatable way?
A whole other.
The Exploration Company, based in Bordeaux, France, has tested a resonance igniter for rocket engines: a new way to start their rocket engines, without external ignition devices.
As the kids say, 🔥
Where is the KSC public radio traffic available?
Excited, and working on a basic S-Band receiver for this. Hoping to finish it before they launch 😅
I want to interrupt your doom scroll to tell folks that a peer team of mine in the Office/M365 org is hiring Linux and/or K8s folks -
If you're interested in driving large scale product decisions and rollout, this could be your role.

Just released Island 🏝️, a sandboxing tool powered by #Landlock.
It auto‑confines processes according to the caller's context (e.g. CWD) and comes with slick Zsh integration, so you can use your terminal naturally without command prefixes. Feedback welcome!

This is AI, right?
