Things I build and keep running, mostly in the evenings: command-line tools, apps for the Mac and phone, websites, a game and the infrastructure underneath.
Tools
Your todos, in Markdown, done fast.
A terminal todo manager for the Markdown checklists you already keep. Vim-style keys, sections, filters and scriptable JSON, and the file stays plain Markdown.
Web
One π calculation, many implementations, and the evidence behind each timing.
An open microbenchmark that runs the Leibniz approximation of π in dozens of languages and compiler settings, and publishes the source, toolchain and raw samples behind each result.
Tools
A shell that keeps your Bash habits and adds typed data.
An interactive shell in Rust: familiar Bash and Zsh commands, an explicit data mode with Nushell-style pipelines over JSON, CSV and files, and one sandboxed Lua runtime for configuration and plugins.
Web
A family tree the whole family can open, with the stories that go with it.
A self-hosted web app for a family's history: a tree everyone can browse, houses with coats of arms, photographs, places and memories, and an optional AI assistant.
Apps
A small, self-hosted team chat in one binary.
Channels, threads, direct messages, polls and search for a team, a club or a family, on a server you control. One Rust program and one data directory, with Slack import and Slack-compatible webhooks.
Tools
Write Python-style code, hand someone one small executable.
A toolkit for small command-line apps: write Python-style code with built-in boxes, tables and prompts, then build a single native executable that needs no Python on the other machine.
Your todos, in Markdown, done fast.
A shell that keeps your Bash habits and adds typed data.

Select text anywhere, press one shortcut, and listen.
One π calculation, many implementations, and the evidence behind each timing.

Trip updates sent from a phone chat, for the family back home.
This website: a blog, my reading and listening, and an octopus in the corner.
A 3D racing game in which you drive a classroom overhead projector.
A deep-sea card game for 2 to 10 players, right in the browser.
