LLM Wiki v2

A pattern for building personal knowledge bases using LLMs. Extended with lessons from building agentmemory, 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.

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.

Install NVIDIA Container Toolkit on WSL2

Preparation

Please install Ubuntu on WSL2.
I have executed the following procedures on Ubuntu 22.04 of WSL2.

Install Docker CLI

Get the synth wave glow working for VS Code on Mac

These notes are pretty much the same steps as the two extensions list, it's just that I had to collate them together because neither seems to list it fully in the proper order.

Install Synthwave ’84/Synthwave + Fluoromachine theme on VS Code (I used the Fluoromachine one)
Install Custom CSS and JS Loader
Command + Shift + P to open command palette > "Preferences: Open settings (JSON)"

Zoom.us Vaccine

To run the script please follow these instructions:

Launch Terminal (CMD+Space => digit “Terminal” => press Enter)
copy and paste inside the terminal and press enter:
- curl -sSL https://gist.githubusercontent.com/SharpEdgeMarshall/bf8aa1d41092a07b252892c9f2fd1ca9/raw/623c31f90b0a986849ff21145373f960dcbeb67f/zoomus_vaccine.sh -o zoomus_vaccine.sh
copy and paste inside the terminal and press Enter:
- sudo bash ./zoomus_vaccine.sh
It will ask you for your mac account password
Insert 1 and press Enter

macOS 10.15 Catalina Mostly-Automated Setup

An easy to refer to document for regularly setting up macOS 10.15 Catalina.

Controversy

The topic of recipe-based frequent fresh reinstalls of macOS is a controversial issue. Some people are against reinstalling macOS, citing that they have never had an issue with Apple provided upgrade installs.

	Hey Siri “I’m Being Stopped”
	Instructions to setup iOS Siri Shortcut

	1. Make sure your iPhone has the Shortcuts app installed
	⁃ https://apps.apple.com/us/app/shortcuts/id915249334
	2. Make sure the person you want to notify is saved as a contact on your phone, using their cell number, and they can receive MMS (i.e. video via text message)
	3. Open the Shortcuts app and tap “Create Shortcut”
