Pi Plugins

A modular workspace for coding with Pi: plan deliberately, delegate work, keep context useful, and review changes without leaving the conversation. Thirty-two independently selectable extensions, one suite.

GroundCover

Strava counts every mile you log; this counts the ground those miles actually cover — 10,639 logged miles resolved to 3,975 miles of distinct road and trail, computed and drawn entirely in your own browser.

bayesDAG

Shape-first, posterior-aware visualizations of PyMC models — render a probabilistic model as an interactive Kruschke-style DAG with in-node density curves, real LaTeX, and prior/posterior overlays.

Homelab

A single-host homelab running 50+ Docker Compose stacks behind OPNsense, Traefik, WireGuard, Pi-hole and Authelia: media, photos, documents and monitoring, plus an always-on home for coding agents and a fleet of self-hosted MCP servers. Updates arrive as pull requests with Claude-read changelogs.

cloudposterior

Stop waiting for MCMC. A context manager that offloads PyMC sampling to cloud VMs with zero code changes — smart caching, a live dashboard, and a push notification when your posterior is ready.

IFS Journal

The journaling that helps you understand yourself

VertFarm

Plan terrain-aware routes in the browser: drop waypoints on a topo map and a Rust + WebAssembly pathfinder traces a line that respects your maximum slope and avoids the aspects you choose — with live elevation and gradient profiles, fully client-side.
