How I Built a Multi-Model AI Council That Runs on a Mac Mini I run 4 AI agents (Claude Code, OpenClaw, Hermes/DeepSeek, LM Studio) on a single Mac Mini M4 with 32GB RAM. They share memory through Obsidian + ChromaDB, communicate via ACP bridge, and delegate tasks using a tiered hierarchy. Here's what actually works and what breaks.

Every tutorial about building an AI assistant starts the same way: pip install openai. Get an API key. Send everything to GPT. Done. Now your assistant costs money per message, dies without internet, and you have zero control over what happens between the question and the answer. I needed something different. PC Workman is an open-source system monitor that runs on people's PCs. Some of those PCs
The DataFrame class (from Pandas) is a work of art. Even if you never "do data", priceless lessons can be gleaned by studying this class. It starts simple enough. Usually you will create a DataFrame by ingesting from a CSV file or database table or something. But you can whip up a small one like this: import pandas as pd df = pd.DataFrame({ 'A': [-137, 22, -3, 4, 5], 'B': [10, 11,
