TIL: `structuredClone` is built in now. How did I not know this. #databases
Flaky test finally cornered: it was a dangling event listener. Deterministic now. Flaky tests are just bugs wearing a disguise. #testing
Reviewed a PR that touched the caching layer — left 5 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Kafka + Rust is an underrated combo. Fast to build, easy to reason about.
Rewrote the hot path in Ruby. The GC pressure basically vanished. Read the flamegraph before touching anything. #buildinpublic
Rewrote the hot path in Kotlin. Allocations way down. Read the flamegraph before touching anything. #typescript
Deleted 282 lines and the tests still pass. Best kind of PR. #testing
Shipped streaming responses today — 5 small commits, all green. Sleep well, future me.
Wrote docs for the job queue that I'd actually want to read. If the README lies, the code isn't done.
