Unix, in JavaScript
David Lister just pointed out this version of Unix, implemented in JavaScript. No, it is not a JavaScript interface to a terminal. Yes, it is a Unix OS running entirely in your web browser. This is probably the most insane thing I have ever seen implemented in JavaScript, and it’s up there in the most insane things I have ever seen. It even has a mini version of the vi editor, and all of this runs in the browser. Wow.
