   This isn't a straight-up integration of liveQuery. We've been very hesitant to bring in liveQuery wholesale because 1) It's quite large and 2) It's very slow (especially when you start using lots of selectors). We didn't want to integrate s

   It's primarily helpful to jQuery itself. The problem is that most libraries have blindly assumed that specific browser bugs (such as an Internet Explorer bug) will exist forever in all versions of the browser. When the time comes for IE to

   So you were capable of doing this in IE3? I'd pay money to see that.

   Do you have any examples? Have you filed any bugs in the jQuery bug tracker? http://dev.jquery.com/

   Well, we could certainly inject new stylesheet rules but that's bound to cause problems since we're at the mercy of the browser CSS engines. I suspect that most jQuery users enjoy writing selectors like "div:first > span" which will be

   "capable of handling HTTP headers" - can you expand on this a bit? Right now you can set HTTP headers in jQuery like so: $.ajax({ beforeSend: function(xhr){ xhr.setRequestHeader("Accept","application/json"); },

   Unfortunately it's not as simple as it is with events. With events you have the advantage of binding to a single point (e.g. the document node) and using the native event bubbling that exists in all browsers to capture any event that occurs

   We aren't really talking about the features of this release, yet, since we want people to focus on testing (to make sure we didn't break anything). But here's a rough breakdown of the code that's in: New Selector Engine (Sizzle: http://git

   I'm definitely considering a 'FireUnitLite' type project which would have the same functionality but in a little JavaScript file that you could include in your site. I'm not sure what you mean by this, though: "seems like the calls need to

    Huh... you're right, it looks totally awesome. I've been using Unison for a while and have been... less than excited about it. I'll have to try this right away.

    Steve is simply labeling the WebKit nightlies as "Safari 4" - it's a little bit heavy-handed but it will, technically, be correct. Probably moving un-released browsers off into another area (Minefield/Firefox 3.1, Safari 4, and IE 8) would

    It already had influence. When the tool came out it helped us to find a regression in redirect caching that occurred from Firefox 2 to Firefox 3. We fixed it and it's back to working again in Firefox 3.1. Steve has good clout - he knows his

    The point isn't to measure something specific at a rate - it's to measure anything to see if the timer results continue to bin the results. It doesn't matter if it's a microbenchmark, or not, at that point. The issue here is that Chrome a

    I definitely didn't intend for it to be that way - only so much as that V8 is the result of a long two years of dedicated work by a team of very smart people who produced an excellent result. Theoretically they reached a point at which they

    In my testing the JavaScript version had a better "boot time" (it was able to begin showing results instantly) - and rendered better/faster for simple examples. However, the Java Applets simply scale better. They can handle pretty much anyt

    Firefox 3 supports native text rendering. There's a couple demos that show this (although you're out in the cold in other browsers, for now at least).

    I don't believe this, at all. A JavaScript library abstracts away frustrating details that aren't related to the JavaScript language: like insane browser bugs. Instead choosing a good library can give you free range to explore the advanced

    I should say that /any/ framework is not intended for performance-critical code. A framework is designed to be an abstraction - abstractions implicitly remove you from what you're trying to do, causing a performance hit of some sort. If per
