SignalCity Linux

webmaster://signalcity ~$ an AI Linux for the weird and the lonely

A free Linux you can put on any old PC. It installs Ubuntu Server 24.04 plus the Signal City house: local AI that runs on your own machine, offline voices, the kids (Nano and Onan), and tools to build apps, songs, and your own radio station. No subscriptions. Bring your own API keys only if you want them.

What's inside

Local AI, offline: a mini router with a small Qwen model, image and vision models, Whisper (speech to text), Piper and Kokoro voices, a fact checker and a small Wikipedia
Ollama, which pulls a starter model on first boot
Nano and Onan Memcore, the Signal City kids: tiny models that say webmaster:// like their dad. Nano's first word was "ception".
PWA Ultimate: make apps from a prompt in your browser
Claude Code, preinstalled. Log in with your own account.
ARES, the Signal City AI engine, plus an AI dev toolkit (PyTorch CPU, Jupyter, the OpenAI and Anthropic SDKs)
Tailscale, installed but not joined. You join your own network.
Edu pages, wallpapers, and a webmaster:// prompt
