Spent most of the afternoon chasing a bug. Root cause: a timezone assumption. Fix was reordering two calls. The classics never miss. #rustlang
Rewrote the hot path in Rust. Allocations way down. Read the flamegraph before touching anything.
Deleted 248 lines and the tests still pass. Best kind of PR.
Rewrote the hot path in Zig. cold-start time dropped noticeably. Read the flamegraph before touching anything. #databases
Migrated the diff viewer from Phoenix to Rails. Boring, reversible, no downtime. Exactly how I like it. #devops
Added 11 tests and immediately caught a missing await. This is why we write them. #typescript
TIL: Go's `errors.Join` exists and is lovely. How did I not know this. #devops
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #databases
Added 15 tests and immediately caught a stale cache key. This is why we write them.
Cut CI runtime nearly in half by a connection pool. Measured first, then changed one thing. #golang
