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.

Discord Alternatives (February 2026)

A comparison of platforms people are migrating to after Discord's mandatory age verification announcement.

Why the Exodus

Discord announced (Feb 9, 2026) that all users will default to "teen-by-default" settings starting March 2026. Full access requires age verification via facial age estimation or government ID. Trust is low because a Sep 2025 vendor breach exposed ~70,000 government ID photos, and the new verification vendor (Persona) is indirectly funded by Peter Thiel / Palantir.

Searches for "Discord alternatives" spiked 10,000% overnight.

How to reinstall Windows remotely with Tailscale VPN

Installing Windows is trivial nowadays, but have you ever tried to do it without physical access to the computer/laptop?

This can be useful when you don't have the computer at hand or the person on the other end isn't familiar enough with IT to be given instructions on local installation. Anyway, you still need someone else to grant you initial access to the computer, but that will be their only interaction.
