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.

I get asked pretty regularly what my opinion is on merge commits vs rebasing vs squashing. I've typed up this response so many times that I've decided to just put it in a gist so I can reference it whenever it comes up again.

I use merge, squash, rebase all situationally. I believe they all have their merits but their usage depends on the context. I think anyone who says any particular strategy is the right answer 100% of the time is wrong, but I think there is considerable acceptable leeway in when you use each. What follows is my personal and professional opinion:

Add SSH-Keys to Bitwarden

Before you can use Bitwarden CLI for your SSH private keys you have to add them to your Bitwarden account. Just create a normal login. The name, username and URI fields doesn't matter for my functions.

Configure Touch ID for the `sudo` command

To allow Touch ID on your Mac to authenticate you for sudo access instead of a password you need to do the following.

`watchman` basic example

I found the watchman docs hard to follow / bereft of useful examples. Below is my attempt at a quickstart guide; see ryan-williams/watchman-helpers for some aliases and other scripts.

0. Install watchman
1. Configure a "watch" on the current directory
- 1b. List currently watched directories
- 1c. Remove a watched directory
2. Set up a "trigger": continuously run a command in response to changes
- 2a. rsync a directory to a remote host
Is there a simpler way to trigger on all files?

Manage Neovim plugins (and more!) with Nix and Home Manager

Highly extensible software like Emacs, Vim, and Neovim tend to grow their own package managers. A software developer, for example, might want to install editor plugins that hook into a particular programming language's linter or language server. The programmer's text editor is therefore extended to support managing additional software to extend the text editor. If this loop continues for too long, the programmer's editor becomes more delicate and complex. The remedy for this problem is to manage software using dedicated tools apart
