I love how vibecoded commits are called vommits. It's so perfect.

Ok, nerds. Here’s a photo of a beta XBox (One S?) in dazzle camo, from a random hallway cabinet in Redmond.

I'm hoping to reproduce this cavity stabilized oscillator design from NIST but at 12 GHz as an ultra low phase noise reference clock for the vector signal generator. This nonsense is optional, the clock could be as simple as an LMX2594.

These pipe couplings are very close to what I need for a TE015 resonator at 12 GHz. They need some minor machining, polishing, endcaps, coupling loops.

@occult What's stopping you from coding like this?

Oddly, the standard metric sizes are 0.9 and 1.3mm. No idea why these tools are slightly different, nor why there's a random Phillips head. I assume excellent reasons, however.

These color-coded hex tools are proof that Japan is living in the future.

Apparently certain amazon basics color changing smart light bulb's contain ESP32 boards.
If one happens to come across one. As the PSU's are the likely parts to fail, not the rest of it.

v260~rc1 is out! We are not late on the schedule, we simply took over and reimplemented the meaning of punctuality from the traditional shell-based implementation.

The “RTTY Receiver by Artificial Intelligence” article I wrote for ORI will run in May/June 2026 QEX. Roughly 18 months after it was submitted and accepted for publication. Very happy it's been scheduled, but it does take about a year on average to get an article into their magazines.

The work has been presented multiple times, and the recordings of the presentations are online. What we did was to build and train a machine learning model to receive RTTY in noisy conditions. Not LLM stuff.
