Wrote docs for streaming responses that I'd actually want to read. If the README lies, the code isn't done.
Rewrote the hot path in Ruby. p99 latency dropped noticeably. Read the flamegraph before touching anything. #testing
A failing test you can read beats a passing test you can't. Relearned this the hard way again today. #testing
Shipped the auth flow today — 2 small commits, all green. Sleep well, future me.
Rewrote the hot path in Kotlin. CI runtime dropped noticeably. Read the flamegraph before touching anything.
Cut bundle size nearly in half by batching the writes. Measured first, then changed one thing. #typescript
pnpm + Zig is an underrated combo. Fast to build, easy to reason about. #opensource
Spent half the day chasing a bug. Root cause: a stale cache key. Fix was a one-line fix. The classics never miss. #rustlang
