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.

LLM Wiki v2

A pattern for building personal knowledge bases using LLMs. Extended with lessons from building agentmemory 20K+ Stars ⭐️, a persistent memory engine for AI coding agents.

This builds on Andrej Karpathy's original LLM Wiki idea file. Everything in the original still applies. This document adds what we learned running the pattern in production: what breaks at scale, what's missing, and what separates a wiki that stays useful from one that rots.

What the original gets right

The core insight is correct: stop re-deriving, start compiling. RAG retrieves and forgets. A wiki accumulates and compounds. The three-layer architecture (raw sources, wiki, schema) works. The operations (ingest, query, lint) cover the basics. If you haven't read the original, start there.

How to Replace an Old Thermostat: Identify Wires by Picture (The Easy AI Way)

If you are searching Google for "how to replace an old thermostat with a smart thermostat" or "what do my thermostat wire colors mean," you are not alone. Millions of Americans buy a new Nest, Ecobee, or Honeywell thermostat, unscrew their old wall plate, and immediately freeze when they see a tangled mess of random colored wires.

You might be asking yourself:

• "Where does the blue wire go on a smart thermostat?"
• "What if I don't have a C-wire?"

Guessing the answers to these questions can permanently fry your new device or blow a fuse on your furnace. But there is a much easier way to do this without hiring an expensive electrician. You can now use thermostatwires.com, an incredibly simple AI tool made specifically for USA homes that lets you identify thermostat wires by picture.

Setup bluetooth on Ubuntu 24.04 with Piperwire (on Raspberry Pi 5)

I've had a hard time bringing bluetooth to work on a Raspberry Pi 5 with Ubuntu 24.04 using Pipewire as audio backend. Maybe you run into the same situation and find this helpful.

With the common tutorials on how to enable a bluetooth speaker connection on Ubuntu, there were the following problems for my combination of Ubuntu 24.04 on a Raspberry Pi 5 and using PipeWire (as of July 2024):

• either the audio quality was fine but the connection automatically disconnects after a few seconds
• or the connection does not disconnect, but the audio begins to stutter extremely after 60 to 90 seconds of audio played

Since Ubuntu 22.10, PipeWire is the default soundserver on Ubuntu, so trying to use Bluetooth with PulseAudio as soundserver would mean to uninstall the recommended default and reconfigure the system.
