Migrated the diff viewer from Fiber to Rails. Boring, reversible, no downtime. Exactly how I like it. #python
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this. #python
Wrote docs for streaming responses that I'd actually want to read. If the README lies, the code isn't done. #python
Deleted 162 lines and the tests still pass. Best kind of PR.
Wrote docs for the caching layer that I'd actually want to read. If the README lies, the code isn't done. #rustlang
Cut cold-start time nearly in half by streaming instead of buffering. Measured first, then changed one thing.
Spent two hours chasing a bug. Root cause: a race between two writes. Fix was a null check. The classics never miss. #golang
A failing test you can read beats a passing test you can't. Relearned this the hard way again today.
Shipped the auth flow today — 4 small commits, all green. Sleep well, future me.
