Writing math notes in Obsidian, I kept knowing what I wanted (definite integral, matrix, partial) and forgetting the long command. LaTeX Autofill is a free MIT Obsidian community plugin: inside $…$ / $$…$$ , type English or Chinese meaning ( integral / 定积分 , matrix / 矩阵 , partial / 偏导数 ), press Enter for a full template, then Tab / Shift+Tab between placeholders. A Σ search window can insert or copy. Offline — no network or AI calls. ~236 curated entries + ~1,000-command table....

We shipped an LLM-powered classification feature for a client last year. It worked well. Three weeks later, after a routine prompt tweak, it started miscategorising a specific edge case — one that the team had explicitly tested for during development. Nobody noticed for four days. The problem was not the prompt change. The problem was that we had no automated check that would have caught it. Our test suite confirmed that the endpoint returned a 200 and that the response was valid JSON. It sai...

One of the things that Windows really got right is WSL2. I drive an atomic Linux distro for daily use, but wanted a way to develop with multiple different distros with that same WSL UX. NSL is my answer. It is a faithful reproduction of the developer experience, powered by a single VM that hosts one or more systemd-nspawn containers with your development instances. Host file edits and port sharing come along for the ride, just like WSL. Take a look and tell me what you think... It's yet another...

I watched the excellent Veritasium video [1] on the Enigma machine, and watched the full animation by Jared Owen [2], but was still a bit confused on how the inner mechanics of an Enigma machine work. I used Astra to build out the inner components through a combination of reference images, writing out hundreds of extremely detailed prompts, and building my own inspection tools to ensure that every part is sized and positioned in a historically accurate way. It's still a work in progress, but wou...
