Dan Luu

DanLuu.com is the personal blog of Dan Luu, known for long-form essays that mix systems thinking with careful measurement and clear writing. The topics range from computer latency and input lag, testing versus informal reasoning, and concurrency bugs, to industry pieces on developer compensation and curated lists of programming blogs worth reading. Many posts include data, historical context, and reproducible reasoning, which is why the site is often cited in courses and shared across the developer community. The design is intentionally minimal, which puts all attention on the ideas.
