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.

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.

For Apple Silicon Macs (M1–M5). Free. No CrossOver license needed.

EU5 has no Mac version, and the popular CrossOver/Wine recipes broke with patch 1.3 "Pavia" (the game hangs or silently dies). This guide gets EU5 1.3 running natively-fast on your Mac — including the 3D terrain, which even working setups usually have disabled — and with a fully working, visible Steam client (no black window, no engine-swapping).

It was worked out on an M5 Max running macOS 26, and every step below was validated on

This tutorial is going to explain the use of regex to match emails using the expression /^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/. This can be useful when validating emails using applications/technologies such as Node (Inqurier) or MongoDB.

A regular expression is a sequence of characters that defines a search pattern. This is commonly used to find patterns within a string, find/replace characters within a string or validate input. This tutortial will go walk through the components of a regex and how it applies to matching an email.
