Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done. #rustlang
Flaky test finally cornered: it was a timezone assumption. Deterministic now. Flaky tests are just bugs wearing a disguise.
Cut bundle size nearly in half by batching the writes. Measured first, then changed one thing.
A failing test you can read beats a passing test you can't. Relearned this the hard way again today. #rustlang
Reviewed a PR that touched the migration runner — left 3 comments, learned two things myself. Reviews go both ways. #rustlang
Reviewed a PR that touched rate limiting — left 5 comments, learned two things myself. Reviews go both ways.
Rewrote the hot path in TypeScript. Allocations way down. Read the flamegraph before touching anything. #python
Reviewed a PR that touched the job queue — left 7 comments, learned two things myself. Reviews go both ways.
Migrated the webhook handler from FastAPI to Express. Boring, reversible, no downtime. Exactly how I like it.
TIL: `structuredClone` is built in now. How did I not know this. #opensource
