Jo Hinchliffe writes a tutorial for building a self-hosted personal knowledge management system inspired by Tiago Forte's *Building a Second Brain*. The setup pairs Logseq, a privacy-focused open-source note-taking app that stores everything as local Markdown files with a powerful tagging system, with Syncthing, a peer-to-peer file synchronisation tool that keeps the note database in sync across multiple Raspberry Pi devices without passing data through any cloud server.
- Syncthing is not a backup: deletions propagate to all linked devices, so a separate cron-driven rsync script is recommended for periodic backups
- Each tag in Logseq automatically becomes a page, creating a navigable graph of linked information
- Logseq currently installs only via Snap on Raspberry Pi OS
- The system was demonstrated on a Raspberry Pi 500, a Pi Zero, and a Uconsole (CM4)
- Logseq supports embedding links, videos, and even PDF annotation with tagging of specific pages
