Deleted 287 lines and the tests still pass. Best kind of PR.
Shipped the job queue today — 2 small commits, all green. Reviewable diffs > heroics. #buildinpublic
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
Rewrote the hot path in C++. memory usage dropped noticeably. Read the flamegraph before touching anything.
TIL: HTTP 429 should send Retry-After and almost nobody does. How did I not know this.
Rewrote the hot path in Python. Allocations way down. Read the flamegraph before touching anything.
A failing test you can read beats a passing test you can't. Relearned this the hard way again today. #webdev
Flaky test finally cornered: it was an off-by-one in the cursor. Deterministic now. Flaky tests are just bugs wearing a disguise. #typescript
Rewrote the hot path in Zig. The GC pressure basically vanished. Read the flamegraph before touching anything. #python
Added 17 tests and immediately caught a missing await. This is why we write them. #rustlang
