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.

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

How to connect PS3 controller to a Mac or PC

This is how you connect PS3 controller to Mac OSX, PC, etc. when previously connected to a PS3. You will need a Mini USB cable. Overcome your laziness, get up of your chair, and go get one!

A big misconception is that keep holding PS button will reset the controller's pairing. It DOES NOT! From my testings, the controller keeps paring with the last machine it was CONNECTED VIA A USB CABLE.

Here are the steps:

runlevel5

#!/usr/bin/env bash

# Simple move this file into your Rails `script` folder. Also make sure you `chmod +x puma.sh`.
# Please modify the CONSTANT variables to fit your configurations.

# The script will start with config set by $PUMA_CONFIG_FILE by default

PUMA_CONFIG_FILE=config/puma.rb
PUMA_PID_FILE=tmp/pids/puma.pid
PUMA_SOCKET=tmp/sockets/puma.sock
