Oh wow, you wrote it all by hand? That's really impressive! :) If the standalone asm.js validator isn't yelling about that and Firefox 25 is, you should let the people who maintain the validator know. They're supposed to be in sync.

Yes, programmed the asm.js core by hand. It was not too hard. One day. The asm.js is also a little bit outdated. It could be around 20% faster. I have never used the standalone asm.js validator. Not even knew, that it exists. The optimizing work in Javascript is really hard. Every few weeks there is a new browser and new mystic speed issues. Firefox 22 without asm.js was the fastest six weeks ago (30-60 MIPS). Then e…

How the heck does a 7MB image come with an entire OS, emulator, and a fully functional game?! You have to wonder how much of our stuff is bloated.

In general a JavaScript-based Linux virtual machine should allow you to run software that would otherwise be difficult or impossible to run in the browser (which right now can be done for a lot of software by compiling it to JavaScript with https://github.com/kripken/emscripten ). Data could be transferred to the VM for processing and then back to "normal" JavaScript using serial I/O. This might prove a useful kludge…

tptacek tells me that secure JS is never going to happen so I don't see a use case there. Yes, proof of concept is cool, until someone steals your private key. No thanks. I suppose though you could non-secure stuff, like add a Python interpreter or C compiler and teach people to code inside the VM. GitHub could provide in-browser syntax checking using a real interpreter/compiler.

Back in the day, you could boot the entire BeOS kernel, filesystem, GUI, network stack, window & task manager, and web browser off of a 1.44mb floppy disk. Ever since then, I've been unable to shake the feeling that something has gone catastrophically wrong with the way we architect software.
