As an old guy, whose first computer, a TRS/80 Model I had 8K of RAM, I'm sad to announce this one.

But not really. There is a gold rush on the horizon.

http://emscripten.org/

code:

#include<stdio.h>

int main() {
  printf("hello, world!\n");
  return 0;
}


With the encapsulated emsdk, on this machine emcc compiles that C code to 9700 lines of Javascript. Some 360K.

code:

$ emcc tests/hello_world.c
$ node a.out.js
hello, world!
 
$ emcc tests/hello_world.c -o hello.html
$ ls -la hello*
-rw-rw-r--. 1 btiffin btiffin 102596 Nov 12 05:50 hello.html
-rw-rw-r--. 1 btiffin btiffin 356065 Nov 12 05:50 hello.js


Which runs in the browser with a full featured terminal emulator, running hello world.

In my old guy opinion, who cares about half a meg between friends. Right? Wear a nice suit and tie, run a demo, go for the gold.

Cheers

The project's page already mentions Unity3D, and if one follows the writeups, we'll soon get the hilarity of

C# -> .Net bytecode -> C++ -> JS+webGL

which means 3D gaming in the browser, plugin free.
