Mozilla & Gecko clones "Over the past year and a half I've been spending more and more of my time working with Mozilla's latest project, Firefox OS. During that time I've fallen in love with the project and what it stands for, in ways that I've never experienced with a technology platform before." I'm not convinced just yet. I hope it succeeds, but I just doubt it actually will.

Another fallen mobile OS.

As it is currently being discussed to death in Reddit and HackerNews, given the way mobile operators and handset makers behave, the amount of failed attempts with alternative mobile operating systems, Firefox OS is most likely going to be the next corpse.

Since it relies on Android compatible hardware and Android underlying lower stack with kernel/drivers - its potential installation base is quite broad. So it won't be a corpse by any means.

So far what's really lacking are devices compatible with conventional (non Android) Linux stack. Samsung's devices for Tizen didn't come out yet to address this, and Jolla's one is supposed to appear next year.

Tizen is much broader than Samsung: http://www.tizenassociation.org/en/

I see a contradiction in the fact that they use HTML5 and JS and that they want it to run on cheap hardware as well as Android.

I highly doubt the claim in the article about javascript game running faster than Android native games. I _really_ want to see some proof of that, because that's really not what I have seen. I mean even on the desktop, HTML5/JS is slow when compared to other technologies.

Also, it's really time for the web browser developers to start working on a real VM for the browser instead of hacking on top of JS. .NET seems like a good example of how you can have a common API shared across multiple languages.

The slowest part isn't JavaScript, hasn't been for a while.

Communication with the HTML-document has always been the slowest part. This is because you are crossing boundries and the page might need to re-render.

Most of the things people should avoid doing are known.

If your Firefox installation supports WebGL proper (see: about:support ) you can run WebGL games fairly close to what the hardware can give you. Just see the demo at: https://developer.mozilla.org/demos/detail/bananabread

For example I use https://addons.mozilla.org/en-US/firefox/addon/pdfjs/ which is a lot faster than loading some plugin or reader. The rendering itself isn't much slower actually.

The slowers part of the language itself is that it is dynamically typed. But that has been solved by detecting the type and by introducing types for large sets of data (Typed Arrays).

Java can be very close to C/C++ performance for a number of things, but definitely not everything. And the startup performance of Java usually sucks.

Javascript is now with proper type support for most things about twice as slow as Java or C.

If you remember that languages like PHP or Perl are 100 times slower than C, then you should see it's not that bad. For example Lua without JIT is something like 50 times slower than C.

I had to go back and re-read that claim - and the claim is that FirefixOS runs webapps faster than the Android *browser*, not than native apps. And that claim is perfectly believable to me.
