The long write-ups, kept off the project pages on purpose. A project page should say what a thing is and let you use it. This is where the measurements go — including the ones that contradicted what I believed when I wrote the code.

How to find every PHP version your repos declare for CVE-2026-109618 and CVE-2026-109619, and which ones need the fix. In 10 public repos, 111 of 112 labeled declarations could not prove which PHP build runs.
I replayed the migration history of 1,000 public Supabase repos. 18.8% had a table the anon key could read at some point, and 10.9% still do.
Six runs of Claude Opus 5.5 and GPT-6 Sol scored 0 on a PDF redaction task I wrote for Terminal-Bench. Each agent tested its own work and believed it had passed.
ESP32 firmware driving eight filament spools for a Bambu Lab printer over MQTT: two sensors per move, a shared TMC2209 step bus, and why unloading needs both.
A Worker in front of static assets buys you things a static host cannot do. Here are the four config decisions that cost me the most time getting there.
What an A1 mini will actually let you do over its local MQTT broker, which parts are confirmed against hardware, and which are still a guess.
Middleware chaining made no sense to me, so I rebuilt it in C++. A year later the profile said the slowest thing was a map I rebuilt on every response.

Things currently unresolved in my own code. They are on the project pages as caveats; they get a post when they get an answer.
The spool module is a human right now. TMC2209 next, and the swap timing is worth a write-up once a motor is doing it instead of me.
