Simulating linux terminal in browser

Question

I have read about Fabrice Bellard\'s linux simulation in browser.

How does Linux emulator in Javascript by Fabrice Bellard work?

Today I stumbled upon this site,

Answer 1

The full linux is http://docker.io, the rest is https://github.com/Runnable/dockworker

We're not simulating the terminal but as Kyle says, replicating the terminal over websockets (with an ajax fallback).

In the browser we're using https://github.com/chjj/term.js which was derived from Fabrice Bellard's emulator. It handles the output, and also the keystroke capture.
