This is completely awesome. When I saw http://cb.vu http://cb.vu a few years ago I thought hey, someone has finally done it, but that turned out to be a hack. Kudos to Bellard once again. Nitpicking: the terminal emulation is messed up. It keeps resizing horizontally, and less gets confused. I'm sure the terminal emulator was fun to play with. A correct vt100 state machine implementation [1] would probably not be quite as fun [2]. There's a vt100.js library used by a couple projects that might improve things.

Indeed, this is completely awesome. I first thought it was some remotely hosted virtual machine, but it really runs inside the browser. Insane! Especially considered how fast it is. When he adds X, we can run Firefox inside Linux inside Firefox inside Linux :') Edit: seems the terminal emulator supports ANSI escape codes such as the 16 Linux colors, but not the XTerm 256 color mode (\e[38;5;CCm) or Konsole 24 bit (\e[38;2;RR;GG;BBm). Guess it could be easily added as it's HTML.

    This would require a server-side component, as the browser has cross-domain limitations and couldn't generate arbitrary network traffic anyway. You could tunnel through websockets, however.

  - wladimir 15y ago
    That would be even better. One could make a Linux device driver to directly access Canvas, WebGL, or even the DOM. It seems that in my post I used "X" as a generic name for "Linux graphics" which is pretty short-sighted.

    Gecko's GTK backend has dependencies on X11, if that's what you were asking about.

  Interestingly, you can run Firefox inside of Firefox... just enter the url: chrome://browser/content/browser.xul

    why??
    - windsurfer 15y ago
      Because XUL is rendered with gecko.

  Sadly my dreams were also crushed when I discovered that lynx wasn't in there. However, wget is there, so all the building blocks are in place.

    As far as I can guess, any networking implementation would have to pass low level requests through a proxy on the server, which would end up making things pretty slow even on an unburdened server.

I just tried out my ansi_colours.sh [1] script and it mostly worked. A few notes: wget is available, and it would be cool to piggy back the linux network stack through the browser. cut & paste support is a must for any terminal The space characters are very narrow. Needs to be monospace. All fairly minor compared to the coolness of this. [1] http://www.pixelbeat.org/scripts/ansi_colours.sh http://www.pixelbeat.org/scripts/ansi_colours.sh
