Hours at the bench, measured — not remembered.

Every number on this page is computed on my machine from four kinds of timestamp: prompts to an AI assistant, commit times, files written, Claude Code session transcripts, and shell sessions. Points less than thirty minutes apart are one sitting, so waiting on a long run counts and a real break does not. Prompts and file contents never leave the machine — only project names and minutes do. Work on private projects is counted, and shown as “private work”.

The day, written by hand

the parts I chose to share

Nothing written by hand yet. The measured hours above are complete on their own; the written day — sleep, food, movement, what I learned — starts soon.
