Anyone who cares about website performance comes to the quick realization that ads are a huge slow down. They are also the source of income for many websites. I somewhat casually mentioned back in December that Google was beta testing an async Google Analytics call. I found a bug in the early [...]

JavaScript Flash Implementation
I meant to post this last week already. Gordon is a JavaScript implementation of Flash. You read that right. It’s written in JavaScript and executes swf files. It’s performance isn’t the same as the Flash player, but it’s surprisingly good.
This is really cool stuff. With JavaScript performance improving people are [...]
Adventures With document.documentElement.firstChild
Here’s an interesting DOM test-case I ran across inadvertently yesterday.
For the purpose of this post assume the following markup:
< !DOCTYPE html>
<html>
<!– i broke the dom –>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Testcase</title>
</head>
<body>
<p>Something</p>
</body>
</html>
If I use document.documentElement.firstChild I don’t get consistent behavior. In Firefox and IE I get the <head/> element, which is what I [...]
Browser Detection In JavaScript Libraries
I was curious what browser detection in various JS libraries look like. While we always try to avoid doing browser detection, it’s sometimes a necessary evil. Here’s what I found.
JSNES JavaScript NES emulator
Ben Firshman wrote a rather impressive NES emulator. There are already quite a few NES emulators out there already this one impressive is because it’s written in pure JavaScript.
Yet another application of “Atwood’s Law“:
Any application that can be written in JavaScript, will eventually be written in JavaScript.
I should note that I mentioned back [...]
JS Super Mario Brothers
Here’s Super Mario brothers rewritten in JavaScript. It’s remarkably well done, even the physics closely match that of the original game. The only thing I noticed was a slight lag in Firefox 3.0.5 which I suspect might be due to the speed of the events rather than the actual game.
There have [...]
MAMA Scripting Analysis
Opera did some interesting research into JavaScript used on the web. As someone who writes a fair amount of JavaScript and reads through countless lines of other people’s scripts, I found this to be pretty interesting.
Overall none of the results were very surprising, though a few things did catch my eye:
Omniture/SiteCatalyst Analytics [...]
jQuery
Pretty big news from the jQuery camp today. Both Microsoft and Nokia will be making it part of their development platforms.
Extra interesting is that they aren’t forking, but utilizing the existing code under the same license, and will contribute and participate like everyone else.
I’ve been using jQuery on sites for quite a while now [...]
Embedded JavaScript For Web 3.0
John Resig has an interesting blog post on embedded JavaScript. It’s something I’ve been thinking about for a little while.
It would be awesome to see a PHP extension to embed SpiderMonkey into PHP. As far as I’m aware Facebook is the only one that’s taken a step in that direction with FBJS, which [...]
