Peek into my brain

What I am reading, watching and thinking about. These are raw signals I drop into my brain (articles, books, quotes, half-formed notes), and an AI helps me organise, tag and present them. For longer pieces written by me, see Writing.

Tip: type #ruby or #agents to filter by tag. Click a tag chip to toggle it.
