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.

Fixing a Microsoft SQL Server LocalDB trigger error

This is a note on how I fixed a relatively minor issue with Microsoft SQL Server Express LocalDB. The solution was a bit difficult to find. Therefore I'm writing this in the hope that it will be found by other people who have the same problem and Google the error message text. This is based on a StackOverflow answer by Yennefer. I've added a bit more detail and an alternative way to delete the triggers. I'm leaving out most of my mistakes, several dead ends, etc.

I'm certainly no expert on anything in this document. I'm just sharing what worked for me.

The error

When I opened Microsoft's Volume Activation Management Tool (VAMT) and tried to connect to my LocalDB instance as usual, I got this error:

 # Usage:
 # This script is designed to be run after you have Solr running locally without SSL
 # It will generate a trusted, self-signed certificate for LOCAL DEV (this must be modified for production)
 
 # Notes: The keystore must be under server/etc on Solr root, and MUST be named solr-ssl.keystore.jks
 # The cert will be added to locally trusted certs, so no security warnings in browsers
 # You must still reconfigure Solr to use the keystore and restart it after running this script
 #
 # THIS SCRIPT REQUIRES WINDOWS 10 (for the SSL trust); without 10 remove the lines around trusting the cert.
