Experimenting and trying out new things is good in principle. Even if you don't agree with this, here's an example of JavaScript taking feedback from CoffeeScript: http://brendaneich.com/2010/11/paren-free/

Define correctness in this context.

it doesn't mean that the language's closure semantics have suddenly changed. Yes, but what are the issues with fresh let-bindings per iteration? Presumably the alternative you mean is where the variables present in the local environment

It's good that Crockford meant semantically, then.

Not ECMAScript Harmony! [1] And no, that isn't the definitive semantics of closing over mutable variables. It is one out of at least two possible semantics. [1] http://brendaneich.com/2010/11/paren-free/ -- see the "Implicit Fresh Binding

While you need a lot of syntactic bullshit to get there, Java does have closures.

The 15 point gap is because Athtar doesn't have up-to-date graphics drivers for WebGL. It's otherwise the same.

Well, they're either stupid or lying. I just used Hanlon's razor to decide.

by sid0 16y ago
Microsoft's being stupid. WebGL is a way to write 3D on the Web, something that's so far not been possible. All the Direct2D stuff is orthogonal -- you can accelerate 2D drawing and provide 3D support separately, as Firefox does.

(1) they are (finally) JITing their JS Just like every other browser. (2) their graphics renderer in using the new DirectWrite lib Just like at least one other browser. Why are people being so negative about it? What does IE do so "na

Yes, that's essentially implied by the Church-Turing thesis. :)

Yes.

I tell them that recursive code is rarely better than iterative code As a general statement, this is wrong. Recursive code is almost always better than imperative code in languages designed to encourage recursion -- I'm thinking of functi

Mere support for CSS transforms is actually really limited. What IE9 and Firefox 4 do on Windows 7 is accelerate all drawing and layer compositing. What it means is that as the browsers gain support for CSS animations and such, they get acc

Firefox already has what they call "full" hardware acceleration, and Safari has none I think, so there's nothing to show there.

HTML is a web technology, but video codecs are needed by a wider range of applications, including playing optical media, games, and presentation software. But inside the browser it's a web technology. That's the whole point of the video t

You need platform-specific APIs to give you direct access to the relevant hardware, which you then need to be able to use efficiently. Yes, and Firefox already has platform-specific Direct3D and OpenGL backends. Remember that a browser

by sid0 16y ago
Is there any valid technical reason for browsers to handle media files in any way other than wrapping OS provided codecs? See http://weblogs.mozillazine.org/roc/archives/2009/06/directsh... . The philosophical reasons are even more impor
259.
by sid0 16y ago
What precludes bundled libraries from having support for hardware acceleration? Firefox 4 accelerates full-screen WebM videos on Windows and Mac, for instance.

Not sure how serious this is, but plenty of languages, particularly functional ones, use = for equality.

by sid0 16y ago
Thanks for that. It's good to see some rigour being brought to something that's hopefully intuitive (long-term gain).

I'm going to post this as a reply to every nitpicker I see bitching about the subjunctive: http://itre.cis.upenn.edu/~myl/languagelog/archives/005515.h... It doesn't matter. Get over it. I also downvoted you for contributing nothing to th

I'm not sure what Dan's point is. Customers know that digital versions cost publishers much less money. Pricing them higher is obviously going to make users feel disrespected and think "greed indeed", as a review stated. And maybe it's beca

I can write C when necessary, but I'd much rather not.

Why is this a problem at all? Isn't closing over a set of mutable variables the standard way OOP is shown to reduce to higher-order functions? I have a great degree of respect for Manuel, and I read his comment, but I still don't see how st

I'm not sure what you mean. The space that Firefox 4 saves by removing the menu bar would just be wasted at the top of the screen.

by sid0 16y ago
What about applications like Firefox 4 that don't require full-blown menu bars? What about applications that want to try out alternative user interfaces (ribbon etc)? What about multi-monitor setups? What about high-resolution (1080p or hig
