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.

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk. This process is also explained at the Nginx ngx_http_fastcgi_module page document page.

Since disk is slow and memory is fast the aim is to get as many FastCGI responses passing through memory only. On the flip side we don't want to set an excessively large buffer as they are created and sized on a per request basis (i.e. it's not shared memory).

The related Nginx options are:

fastcgi_buffering appeared in Nginx 1.5.6 (1.6.0 stable) and can be used to turn buffering completely on/off. It's on by default.

	RDP Eavesdropping and Hijacking
	*******************************
	I spent some time this evening looking at ways to eavesdrop and hijack RDP sessions. Here is a gist of (semi) interesting findings
	that is not very new...

	===========
	Inspiration
	===========
	As you may already know...

	#!/bin/bash

	# Desktop build
	MAKE="make -j 4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-"
	# C.H.I.P. build
	#MAKE="make"
	CDIR=$PWD
	LINUX=$CDIR/CHIP-linux
	WIFI=$CDIR/RTL8723BS

	var debug = process.env.NODE_ENV !== "production";
	var webpack = require('webpack');

	module.exports = {
	context: __dirname,
	devtool: debug ? "inline-sourcemap" : null,
	entry: "./js/scripts.js",
	output: {
	path: __dirname + "/js",
	filename: "scripts.min.js"
