Edge latency atlasA world map that measures real round-trip latency from your browser to 30 Cloudflare locations, then draws the results as a contour field.SQLite on the edgeWorking out where the boundary between D1 and a Durable Object actually belongs, using a shared expense ledger as the excuse.A single-file CSS engine that renders to canvas and falls over on deeply nested selectorsA toy CSS parser and layout engine with no dependencies. It worked until it met a selector four levels deep, and I stopped there.Terminal heatmapReads shell history and prints a calendar heatmap of which commands you actually run. Small, finished, and slightly uncomfortable to look at.
About
I build small things to understand how they work. Most of these start as a question I cannot answer without writing code, and end as something half-finished that still taught me what I wanted to know. I write them up honestly, including the ones that did not work out.

Open to interesting problems and the people building them.
