LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

GNOME Keyring Auto-Unlock for Autologin Systems

This guide sets up automatic keyring unlocking on Ubuntu/Zorin systems with autologin enabled. This allows startup scripts and services (like RDP) to access stored credentials without manual intervention.

Why Use Passwords on Keyrings?

While empty passwords are simpler for autologin, recent Ubuntu versions have a bug where keyrings with empty passwords can get randomly reset/corrupted after updates. Using a password prevents this data loss.

Note

I’ve written a newer optimized 2026 version of this guide with a faster setup using Zinit + Starship and improved plugin loading.

This version avoids slow shell startups and works better with modern Zsh setups.

Oh my zsh.

After latest April 2026 update to Ubuntu 24.04 LTS, thumbnails are no longer being generated

Steps to fix it:

Relax the security restriction (immediate fix): Open your terminal and run:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Clear the "failed" thumbnail cache: This forces Nautilus to retry generating thumbnails for files that previously failed:

	# AI-powered Git Commit Function
	# Copy paste this gist into your ~/.bashrc or ~/.zshrc to gain the `gcm` command. It:
	# 1) gets the current staged changed diff
	# 2) sends them to an LLM to write the git commit message
	# 3) allows you to easily accept, edit, regenerate, cancel
	# But - just read and edit the code however you like
	# the `llm` CLI util is awesome, can get it here: https://llm.datasette.io/en/stable/
