Linux Kernel Running In JavaScript Emulator With Graphics and Network Support 177
New submitter warmflatsprite writes "It seems that there have been a rash of JavaScript virtual machines running Linux lately (or maybe I just travel in really weird circles). However until now none of them had network support, so they weren't too terribly useful. Sebastian Macke's jor1k project uses asm.js to produce a very fast emulation of the OpenCores OpenRISC processor (or1k) along with a HTML5 canvas framebuffer for graphics support. Recently Ben Burns contributed an emulated OpenCores ethmac ethernet adapter to the project. This sends ethernet frames to a gateway server via websocket where they are switched and/or piped into TAP virtual ethernet adapter. With this you can build whatever kind of network appliance you'd like for the myriad of fast, sandboxed VMs running in your users' browsers. For the live demo all VMs connect to a single private LAN (subnet 10.5.0.0/16). The websocket gateway also NATs traffic from that LAN out to the open Internet."

The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser. The final choice of name caused confusion, giving the impression that the language was a spin-off of the Java programming language, and the choice has been characterized by many as a marketing ploy by Netscape to give JavaScript the cachet of what was then the hot new web programming language.

All we need now is JS acceleration built in to cpus.
Yo dawg, I heard you like VMs so..
