title: How does Linux emulator in Javascript by Fabrice Bellard work?
body: <p>Today I had a jaw dropping moment, when I saw Linux emulator in Javascript:
  <a href="http://bellard.org/jslinux/">http://bellard.org/jslinux/</a> </p>
  
  <p>It compiles C programs, it has vi and emacs, it supports all shell commands, etc etc. </p>
  
  <p>How does it work?</p>
