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.

Practice

SLA and Multi-Regions setup

For 2 9s (99%) and 3 9s (99.9%) scenario, a single region setup is enough.

TLTR;

RED=$'\e[0;31m'
R=${RED}
BLUE=$'\e[0;34m'
B=${BLUE}
GREEN=$'\e[0;32m'
G=${GREEN}
CYAN=$'\e[0;36m'

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)

UFW cheat sheet

Usage

ufw [--dry-run] enable|disable|reload
ufw [--dry-run] default allow|deny|reject [incoming|outgoing]
ufw [--dry-run] logging on|off|LEVEL
    toggle logging. Logged packets use the LOG_KERN syslog facility. Systems configured for rsyslog
    support may also log to /var/log/ufw.log. Specifying a LEVEL turns logging on for the specified LEVEL.
