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

@llvm IMHO, Perl is underrated in the hands of someone with good taste & OO design skills. But not by much.

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.

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.

No Tools for You: A Century of Men Policing Women’s Tools

In 1925 a doctor said vacuum cleaners will make women lazy. In 2026 mastodon dudes said the same thing (and worse) about a woman engineer using a tool to make a CAD part.

Pascal lives!

I've uploaded some filter simulation source (WGFIL & INTRFIL) to github with the permission of the author, Dennis Sweeney WA4LPR.

https://github.com/xjamesmorris/wa4lpr_filters

It was fun building these in the Free Pascal IDE, which will be familiar to anyone who grew up on Turbo Pascal.

I sometimes wonder what we threw away when folk moved on from Pascal. Did we end up with anything better?
