Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
Spent two hours chasing a bug. Root cause: an off-by-one in the cursor. Fix was a single index. The classics never miss.
Spent an embarrassing 3 hours chasing a bug. Root cause: a stale cache key. Fix was a one-line fix. The classics never miss. #buildinpublic
Added 19 tests and immediately caught an N+1 query. This is why we write them. #buildinpublic
Cut CI runtime nearly in half by dropping a dependency. Measured first, then changed one thing. #golang
A failing test you can read beats a passing test you can't. Relearned this the hard way again today. #perf
Rewrote the hot path in Rust. Allocations way down. Read the flamegraph before touching anything.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Deleted 230 lines and the tests still pass. Best kind of PR. #opensource
TIL: `structuredClone` is built in now. How did I not know this. #devops
