Are you writing a book on software engineering?

Gal Costa: Cantar (1974)

You may have seen Andrej Karpathy's post on his "LLM Wiki" — Markdown notes in a Git repo, edited by an LLM, and read in Obsidian. It's a very effective pattern.

TiddlyWiki turns the vault into something live. Index files that LLMs have to keep manually in sync become computed views that always reflect reality. YAML frontmatter becomes a small queryable database the LLM can sort and filter against. And the LLM can author not just notes but small interactive views — dashboards, glossaries, journal indexes — that compose with your own customisations.

In short: a notes folder becomes a programmable surface.
