Patinate

Render Strava activity into stylized heatmap posters and inline SVG. A single Rust binary keeps a SQLite activity cache, draws it over an OpenStreetMap basemap in one of four baked-in themes, trims every track inside a privacy circle before render, and can strip identifying attributes on the way out. The patina builds where you ride often: overlapping low-alpha strokes accumulate into brighter color the way actual patina builds on metal.

kit

A tool-registry manager that resolved developer tool versions across git-based TOML registries, generated mise configuration from the result, and verified every install against a per-tool trust tier, from cosign down to a bare checksum. Three CI pipelines proposed and gated the bumps until mise covered the same ground.

Get Lamp

On dark software factories, where they work, where they might not, and a tool we built to explore the gap.

Go Architecture for LLM-Maintained Codebases

Structural choices in a Go project built mostly by LLMs: making wrong code fail to compile rather than fail code review.

Back to Composable

Birthday at the Theater

Alasdair turned three and we threw him a party at the theater, which required splicing together TV episodes, phone-recorded introductions, and Ken Burns effects on Route 66 maps.

Harness Explorer

Static analysis for the AGENTS.md, CLAUDE.md, and skills files that define how an agent behaves in a codebase. A single Go binary follows their references into a knowledge graph, scores it for redundancy, contradiction, and information density, and ranks where the next hour of harness editing saves the most tokens; whether that ranking approximates what matters is untested, since no calibration dataset exists.
