Moving to NYC, One Home Assistant Integration at a Time
An international move, a train to catch, three AirTag bracelets, and a spider: building a household app with Home Assistant, local financial data, and useful AI.
Hash Devlog: A Shell That Writes Its Own Tab Completions
bash and zsh let you extend tab completion by writing shell scripts, which is why I never do. Fish does it better, but I'm lazy. Hash goes further: a completion plugin takes about thirty seconds to write, and the shell's own agent can write it for you.
Binary vs JSON for MCP: I Went Looking
Protobuf beats JSON. GraphBinary beats GraphSON. So I went looking for where a binary wire helps MCP. The answer, in the venues I tested, was narrower and more interesting than I expected: not text-heavy tools, not JSON-optimized structured payloads, but exactly where JSON is forced to fake binary.
Learning Jujutsu by Teaching It
Building an interactive learning tool for jj, inspired by learngitbranching.js.org, because the best way to learn is to teach.
Hash Devlog: Setting Up for Daily Driving
Building the infrastructure to use Hash as my daily shell: version injection, Homebrew distribution, and a quick way to report bugs from the terminal.
Hash Devlog: Tracing the Missing Keystrokes
Keystrokes were vanishing. Claude couldn't find the bug. So I built a trace system and caught orphaned goroutines fighting over stdin.
Introducing Hash: Building an Agentic Shell
Why I'm building Hash (Harness Assisted SHell) - a Go-based shell with editor-style input, Helix keybindings, and agent-agnostic AI integration.
