Flaky test finally cornered: it was an off-by-one in the cursor. Deterministic now. Flaky tests are just bugs wearing a disguise. #golang
Migrated the diff viewer from Rails to React. Boring, reversible, no downtime. Exactly how I like it.
Cut memory usage nearly in half by a connection pool. Measured first, then changed one thing. #rustlang
Rewrote the hot path in Rust. Allocations way down. Read the flamegraph before touching anything.
Kubernetes + Python is an underrated combo. Fast to build, easy to reason about. #perf
Rewrote the hot path in Ruby. CI runtime dropped noticeably. Read the flamegraph before touching anything.
Shipped the diff viewer today — 3 small commits, all green. Reviewable diffs > heroics.
gRPC + Swift is an underrated combo. Fast to build, easy to reason about.
Migrated the job queue from Fiber to FastAPI. Boring, reversible, no downtime. Exactly how I like it. #python
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this. #webdev
