This is awesome.

You might want to consider re-ordering the font list in the console though. Consolas isn't perfectly fixed-width apparently, and it made Rogue rather puzzling to play.

This may as well be magic as far as I'm concerned. When I first saw http://bellard.org/jslinux/ I just about shat myself. This is definitely another level of awesome. Well done.

This really is extremely well done [and I'd like to see the unminified source]. The next feature I'd want to see is networking support. I love the idea to be able to run my entire dev setup in an emulated browser session [e.g. ruby, rails, redis]. That would be a game changer on how I'd develop.

I tried the freedos image, says something about 400kips and then down to 0. Nothing ever shows. FF 17.0.9 ESR on 1386 freebsd 8.3

Yeah! Especially X - that's a pretty amazing X implementation!

It's not an X implementation, it's VESA emulation (disclaimer: this is a guess).

Good guess, that's correct

At 2000 kIPS you may have a few generations of javascript engines to go before we get there.

That's not meant to take away from this project - it truly is amazing what can be interpreted in the browser now.

no network interfaces :( boo. rm -rf or halt -f are fun.

this is great work. would love to see source un-minified.

Is there a non minified version of the javascript emulator file that is publicly available?

I'll put it online soon. I haven't figured licensing out yet and need to write some technical notes

Networking is on the todo list. I couldn't host the traffic, though.

Yea, Chrome DevTools has a pretty print option too, but if they ran it through something like closure compiler it renames all the vars. Would like to browse source on github or comparable -- also see the history :)
