If the same thing is covered in five different places, it's the same as having no notes. The hard part is holding this line as sources pile up. note-supplement handles merging outside materials back into existing notes, without breaking the things you already got right.https://drpwchen.com/en/posts/textbook-to-note/Sun, 19 Jul 2026 15:45:00 +0800https://drpwchen.com/en/posts/textbook-to-note/With over forty designated reference books for the board examination, and the same concepts scattered across multiple books, how could anyone possibly finish reading them?

I cleaned up and open-sourced the "semantic search trio" I've been using for the past half-year. It's completely local and MIT-licensed.https://drpwchen.com/en/posts/vault-graph-rag/Mon, 22 Jun 2026 15:00:00 +0800https://drpwchen.com/en/posts/vault-graph-rag/I threw a new paper on SQL-RAG at Claude to verify it myself: useless for a redundant textbook library, but a great fit for finding "related notes" in a sparse Obsidian medical note vault. After swapping the ranking to personalized PageRank, the proportion of correctly finding related notes jumped from 34% to 84%, and I put it straight into production.
