back to article Linux kernel runs inside web browser

An independent programmer has used JavaScript to build a PC emulator capable of running Linux inside a web browser. French hacker Fabrice Bellard says his JavaScript PC Emulator can run the 2.6.20 Linux kernel inside Mozilla's Firefox 4 and Google's Chrome 11, two browsers designed to significantly advance JavaScript speeds.

        @David Hicks, absurdity

        OK so it doesn't work on an iSomething yet. But how long before we see Steve Jobs start trashing Javascript?

        The language is only going to get faster on Androids, Blackberries, etc. and as it does so the opportunities for things like this to become more serious and more capable will only increase.

        Now it would be an absurd way to run whatever software you like on a phone. You'd need a pretty good network connection for storage (I'm presuming that Javascript can't store data locally on an iPhone). The battery consumption is going to be terrible in comparison to running an equivalent native application. But with such restrictive practises eminating from His Jobness it is quite possible that absurdity will not be such a high barrier afterall.

          @bazza

          Apple shipped a major speed boost to the Javascript engine in Mobile Safari in iOS 4.3, though they got slammed — rightly or wrongly — for not applying it to the entire OS. It's not just "going to get faster on Androids, Blackberries, etc", it is getting faster on Androids, Blackberries, iPhones, etc.

          The iPhone supports the latest HTML 5 database stuff, for local persistent store, as does Android. Blackberry doesn't.

          Even since the App Store launched and Apple stopped saying "HTML + Javascript is the API", they've failed to become more restrictive. Every added restriction on one side, such as the 70:30 rule for subscription content, is balanced by one eased on the other, such as the removal of the C/C++/Objective-C/Javascript rule for apps which allows people to use Adobes development tools if they wish.

          To my knowledge, Jobs has spoken out publicly only against Flash. The arguments he made that it offers a very poor user experience on mobile have been backed up by every objective review I've seen of the Android client. I doubt I'm alone in having decided never to download the thing onto my Android phone. His conclusions — to ban Flash from his platform — betray his control tendencies but the initial observations were valid.

          So, in response to your post: (i) Apple have been improving their Javascript implementation; (ii) Apple do support local storage for Javascript applications; (iii) Apple's maniacal level of control over the iPhone platform has remained more or less constant rather than being some sort of ever-growing all encroaching beast; and (iv) Jobs has publicly trashed technologies only when they deserve to be trashed (his actions following the trashing being the objectionable bit, not the trashing itself).

          History has also shown Apple to be a beneficial contributor to the web ecosystem, being the driving force behind the vast majority of WebKit development (it was forked from KHTML when that project was four years old, which was nine years ago) and the originator of the canvas element and 2d/3d CSS transforms amongst others. As far as I can think, they've done nothing at any time to hurt the development and propagation web standards.

          I'd therefore suggest that Javascript will remain just as viable on iPhones as everywhere else in the world, give or take that Apple's Javascript implementation tends to lag Google's in speed increases.

        FB's name is attached to his useless (although amusing) hack. It's a good hack, I'll go there ... along the lines of SCO's UNIX port to the 8088. But unlike the original SCO[1], FB seems to be calling attention to himself; showboating, if you will.

        Me? Not so much. I'm not exactly putting my name out there, now am I?

        This hack is *roughly* equivalent to writing an 8088 emulator in Qbasic, and then running MSDOS 3.0 on it under MSDOS 5.0 on a 386sx16 ... Looking at it that way, it's kinda pointless, no? FB could do a lot more good working on video & wireless drivers instead ...

          no idea what you mean by "SCO Xenix"

          but I'm confused by your definition of hack. Writing a processor emulator isn't a hack. Making an existing piece of software do something it wasn't designed to is a hack. Javascript is a language and this guy has written an emulator in it. He hasn't hacked anything, he's created a pretty cool piece of code.

          This isn't roughly equivalent to doing anything in Qbasic. Javascript is everywhere these days, on devices of all sizes from many manufacturers, running server side and client side. So this actually enables 486 emulation just about anywhere.

          You consider this work to be kinda pointless? He did it for fun. If you don't think having fun can be a valid reason for doing something then your life must be a bundle of laughs......

            I had VM hardware machines "just about anywhere" on bare hardware a couple decades ago, WITHOUT the need of an additional OS, browser, scripting language, and hardware emulator to run the OS and software.

              "Basic was the javascipt of the late '70s, 80s & early '90s"

              Well, sort of, but javascript implementations are all based on w3c script standards. QBasic wouldn't run on a commodore pet, a spectrum or an atari st. Whereas Javascript is genuinely able to run on devices from mobile handsets to web servers. So I disagree here, basic is too fragmented and non-standard to claim it's the same as contemporary javascript.

              "I had VM hardware machines "just about anywhere" on bare hardware a couple decades ago, WITHOUT the need of an additional OS, browser, scripting language, and hardware emulator to run the OS and software"

              These days most pcs have an os, browser and scripting language. So running this would be much less effort than setting up the bare hardware and virtual machines you mention. So maybe keeping it simple from a client perspective is also valuable?

      Why?

      "... and then you re-implement that OS on top of that scripting language?"

      No, then you implement some virtual hardware capable of running the original implementation of that OS. The end result may currently appear the same - OS running within a browser, woo - but whereas re-implementing the OS would have only ever given us the ability to run that OS within the browser, implementing a virtual PC instead gives us the potential (within the restrictions of the virtual hardware) to do other stuff too.

      There's lots of uses for a JavaScript x86 emulator

      It's worth noting that the emulator isn't emulating the OS; it's emulating the hardware which the OS runs on. Which makes it a lot more useful.

      I've no doubt that this was at least partially done just because it could be done, and the limitations of JavaScript mean it's severely hampered in some respects (file access, network access, etc). Then too, it probably needs a few optimisation passes - 486-level performance isn't particularly useful these days. But the point still remains: with JavaScript interpreters being so widely available, this provides a sandboxed way of running x86 code on virtually any piece of modern hardware in the world, whether it's a phone, tablet, laptop, settop box or something else altogether...

      It's also worth noting that while it's probably the most ambitious JS-emulator to date, this is far from the first - there was a ZX Spectrum emulator released back in 2008...

      it has a lot of Potential aplications.

      With it you could theoretically test any program for one OS AND architecture on top of another.

      Heck you could automatize testing by running a program with deferent virtual peripherals.

      Imagine if a game companies could taste their games on any imaginable hardware configuration without having to actually buy and set the irons.

      Security implications probably very significant

      Once the next model comes out with a network adaptor. But, my (possibly wrong) understanding of Javascript is that this should only be able to network with the site your browser obtained the Javascript code from ? I can still see some very useful potential applications for that.

      Other interesting security implications is that this will enable somewhat more serious fuzz testing of Javascript implementations. I expect to see some significant sandbox breakouts reported as a consequence, and intelligence agencies will of course be very interested in obtaining zero day exploits which don't get patched and which they can use for targeted client exploits.

    And for those who say "why?" I say "why not?".

    I bet these were the same people who were naysaying virtual machines in the late 90s...

    Why

    In answer to the question, Why? I would cite "Lemmings" as one of the least useful programs ever made. But one of the best.

      Lemmings you say?

    It's Linux that he's used.

    Well, RMS is proven right again, we should be saying GNU/Linux when talking about the operating system.

    GNU is an operating system that can use Linux as it's kernel.

    To other posters (just a couple of them) ...

    No, you can't do rm -rf, that would require the GNU operating system and GNU rm. Look it up.

    Run "Linux" and then Firefox and then load Linux etc recursively. No, because that would take the GNU/Linux operating system at each level.

    Sorry to get annoyed about this but how are we supposed to have any sort of sensible conversation about the very interesting thing that this guy has done when people's understanding has been so corrupted.

      Stop.

      Saying "GNU/Linux" ... ain't gonna happen. Sorry. You can complain. Or realise your battle was lost a long time ago. Back in ... say ... 1991. The weight of bodies is against you. Stop being so prissy. It's not that we don't understand. It's that we're human. And lazy.

      In fact, I don't even know how to say it. Gee Enn You Slash Linux? Noo Linux? Guh Noo Slash Linux? Oh ... apparently it's the last. Fuck off, Stallman.

      "No, you can't do rm -rf, that would require the GNU operating system and GNU rm."

      Frankly, that almost makes me want to use windows.

      BusyBox v1.18.3 (2011-05-14 13:22:58 CEST) multi-call binary.

      I'm sorry, but this is BusyBox. BusyBox is GPL, yes, and they have gone after GPL violators, yes... but that doesn't suddenly make it GNU coreutils! Even though there may be some kind of GNU in there (I'm not /exactly/ sure what's part of the provided JS/Linux), it is possible to make a Linux-based OS without enough GNU software to warrant it calling GNU/Linux.

      Sheesh

      It 's enough to make me want to sit down and write replacements for all the GNU utils just to stop nonsense like this and I only know Javascript.

      Wait . . .

    Yes, but

    can it run Duke Nuke'em 3D on it?

    Nice idea, with one further addition..

    If he went a bit further and added an emulated Gravis Ultrasound card, then you've got the perfect mid-nineties demo scene rig. Crystal Dream 2 anybody?

      Future Crew, please come back and show the modern pretenders how it's done!

      (that said, Farbrausch have done some p. cool stuff...)

    Quite a feat (being kind-of useless as such makes it Art :).

    iPad

    I _think_ it's running in Safari on the iPad. I get a green flashing cursor on black.

    BUT I can't get it to show the keyboard, so I'm a bit stuck...

    Damn, that would have ben fun ;)

      It didn't get to the cursor this morning plus now there's a clipboard button and text field too.

    If this can run in a web broswer,

    then what the hell is wrong with Flash?

      Not sure the way you meant

      But this actually uses less CPU % than Flash does doing much less.

      I'll tell you what's wrong with Flash .....

      Absence of Source Code is what's wrong with Flash.

    I cleverly switched this around...

    ...by running a web browser from within an installation of Linux.

    Paris, because, we're both, like, well smart.

    JS has sure come a long way

    I remember when it was only used to put annoying scrolling text on the status bar and disable right-clicking.

    The man's a genius

    There is no other word for it. I saw his name at one of the French science museums a couple of weeks ago in relation to Pi - he smashed the record for generating the number of decimal places.. on a PC - and thought 'I recognise that name'.

    Stick DR/PC/MS-DOS on this one, and you could run his first claim to fame, LZExe, on it.

    Turing Award?

    Coming from a Browser Development and Q&A background, Id say this emulator needs a nomination for a Turing Award. This is probably the geekiest and overall coolest thing ive ever seen run in a browser. If Thacker can get it for Ethernet and the Alto, Bellard needs to get it for a Browser-based Linux emulator.

    Maybe Google isnt completely full of shit with a browser based OS after all...

    It can run DOS games...

    .. but does it run 'em slow enough?

    Now where did I put my copy of Ancient Art of War...
