aos
While ao is a hyper parallel computer that enables distributed compute, aos is an operating system on top of that computer.
With aos you can interact with processes and you can code processes in a very simple and intuitive way. All you need is a terminal and an editor.
The language chosen for aos is lua, which is a robust and deterministic dynamic language that is a lot of fun to work with.
