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.

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Anchors in Markdown

To create an anchor to a heading in github flavored markdown. Add - characters between each word in the heading and wrap the value in parens (#some-markdown-heading) so your link should look like so:

[create an anchor](#anchors-in-markdown)

	#!/bin/bash
	#
	# script to extract ImageNet dataset
	# ILSVRC2012_img_train.tar (about 138 GB)
	# ILSVRC2012_img_val.tar (about 6.3 GB)
	# make sure ILSVRC2012_img_train.tar & ILSVRC2012_img_val.tar in your current directory
	#
	# https://github.com/facebook/fb.resnet.torch/blob/master/INSTALL.md
	#
	# train/

	>>> import sys

	OR

	$ which python3
	/usr/local/bin/python3

	# add the GPG key for the official Docker repository to the system
	curl -fsSL https://download.docker.com/linux/ubuntu/gpg \| sudo apt-key add -

	# add the Docker repository to APT sources
	sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

	# update the package database with the Docker packages from the newly added repo
	sudo apt-get update

	import tensorflow as tf

	usage_str = 'python tensorflow_rename_variables.py --checkpoint_dir=path/to/dir/ ' \
	'--replace_from=substr --replace_to=substr --add_prefix=abc --dry_run'


	def rename(checkpoint_dir, replace_from, replace_to, add_prefix, dry_run):
	checkpoint = tf.train.get_checkpoint_state(checkpoint_dir)

	% VOCLABELCOLORMAP Creates a label color map such that adjacent indices have different
	% colors. Useful for reading and writing index images which contain large indices,
	% by encoding them as RGB images.
	%
	% CMAP = VOCLABELCOLORMAP(N) creates a label color map with N entries.
	function cmap = labelcolormap(N)
