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.

Generate Symantec VIP Access Token as OTP

Recently I came across a web service that required two-factor authentication using the Symantec VIP Access App. I already manage all of my OTP tokens in a different app (If you are on iOS I highly recommend using OTP Auth by Roland Moers.) and did not want to have to use yet another app to generate the TOTP.

There is a way to generate a Symantec VIP Access compatible token very easily if you have access to an environment which can run Python PIP. I happen to have Ubuntu Windows Subsystem Linux running on my machine. (If you are running Windows 10 and don't have this you should really check it out.) Let's get started...

Instructions

Here we install python3-pip and qrencode so we can generate our secret, I

Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

CPU-bound
Blocking IO
Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

Using `<details>` in GitHub

Suppose you're opening an issue and there's a lot noisey logs that may be useful.

Rather than wrecking readability, wrap it in a <details> tag!

Private members in ES6 classes

"Let's create an ES6 class!" you say. "Let's give it a private variable x."

class Foo {
  constructor(x) {
    this.x = x;

Multiple MySQL Versions for Development

Options included below:

Using Docker docker-compose
Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

Install

Modify index.txt with your output path and proxy info
Use Text Builder to build configuration for Surge: $ text-builder -index /path/to/index.txt Or run $ sh build-all to build all your index files.
