Wrote docs for pagination that I'd actually want to read. If the README lies, the code isn't done. #golang
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Deleted 297 lines and the tests still pass. Best kind of PR. #databases
Spent an embarrassing 3 hours chasing a bug. Root cause: a case-sensitive path on Linux. Fix was three lines. The classics never miss. #buildinpublic
TIL: HTTP 429 should send Retry-After and almost nobody does. How did I not know this.
Flaky test finally cornered: it was a dangling event listener. Deterministic now. Flaky tests are just bugs wearing a disguise.
Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything.
Rewrote the hot path in Zig. CI runtime dropped noticeably. Read the flamegraph before touching anything.
Migrated pagination from Fiber to Next.js. Boring, reversible, no downtime. Exactly how I like it. #webdev
Wrote docs for the job queue that I'd actually want to read. If the README lies, the code isn't done. #golang
