I'm very excited about C++26 reflection. However, people underestimate what you can achieve *today*!
Inspired by Barry Revzin's awesome "Practical Reflection" talk at @cppcon.bsky.social I wrote automatic Dear #imgui generation for structs, including labels! (via Boost.PFR)

Orienting a RigidBody with precision timing requires something beyond a naïve "accelerate-towards-target" method. Here's a slow-motion comparison between the naïve method vs. what I call the "Akira slide". Green line indicates acceleration.

Writing my own disk drive cleaning program today because I don't like how other programs do it. (Mine uses a butterfly pattern, and only runs for 20 seconds, because that should be long enough to unjam any gunk from the heads.)

Rednex's publisher has decided that me playing their game, which included 10 seconds of their music in-game, was not "fair use." Even though it quite clearly is. Another case of YouTube's copyright system being absolutely broken as fuck. I have no choice but to relinquish monetization of that video.

A rare example of Vault Corporation's "PROLOK" copy protection scheme on a 3.5" floppy disk.
Vault used some method - probably a laser - to remove the oxide coating from one side of the mylar disk, making it impossible to write to.

Before I got deep into the retro computing hobby, I dabbled in watercolors.
My art desk is now an electronics workstation cluttered with equipment and various Arduino projects.
I kinda miss painting though. I wish I had the space to have both hobbies.

This CrowdSupply item - the ESP32JTAG - just went live, and it has a lot more functionality than I thought it would when I first heard about it.
Impressive.
Also, 40% of the way to its target, and it only started a few hours ago.
