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.

kubernetes shortcuts & cheatsheet

Use a DaemonSet for Pods that need to run one per machine, because they provide a machine-specific system service.

Learning k8s basics

For example, to mark a node unschedulable, run this command:

How to build reconnect logic for amqplib
var amqp = require('amqplib/callback_api');
// if the connection is closed or fails to be established at all, we will reconnect
var amqpConn = null;
function start() {
amqp.connect(process.env.CLOUDAMQP_URL + "?heartbeat=60", function(err, conn) {

PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
