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.

Change MAC Address Permanently

It is well know that through the ip and ifconfig commands it is possible to change a MAC address temporarily, meaning the change will not persist across host reboots.

But what if you would like to change your MAC address in a more permanent fashion? Is there a way to, through software, permanently change your network interface card's MAC address?

It turns out the answer is yes, and the tool to do so is called ethtool.

Ethtool

Ethtool comes pre-installed on many stock distributions of Linux, but can also be installed from your package manager of choice if necessary.

Getting it to work

The device is shipped with test firmware installed. To burn a proper firmware, you will need:

• Atmel USB DFU Programmer from https://sourceforge.net/projects/dfu-programmer/
• Actual firmware files, which in worst case scenario you have to build yourself
• Incorrect instructions from https://store.ryscc.com/blogs/news/upgrading-the-firmware-on-a-chameleonmini
• Correct instructions (and a .bat file) in the firmware documentation

The instructions on the blog page are incorrect because Rev G hardware uses ATxmega128A4U instead of ATxmega32A4U. Why? Probably an outdated version of hardware.
