How I think about software engineering.
Long-form notes, a four-ring tech radar, and the projects behind the opinions. Evidence over hype, trade-offs over takes — from an engineer who'd rather tend a codebase than rewrite it.

Reading the Postgres planner without flinching
A field guide to EXPLAIN (ANALYZE, BUFFERS): what the planner tells you, where row estimates go wrong, and the three rewrites that fix most slow queries.

Driftwood
An incremental build cache for static sites. It fingerprints content rather than file timestamps, so editing one post doesn't invalidate the world — only the pages that actually changed get rebuilt.
