Even the simplest rewrite rule—say, replacing a deprecated message with a new one—usually sends me hunting for examples. During this project I spent a lot of time deep inside the rewrite engine, and even now I cannot reliably recall the exact syntax.
Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
