Forget AMD and that's straight from the source. Sorry for the long build-up on the history, but if I'm to convince you to forget this non-technology, I think it's best you know where it came from. For those in a hurry, the executive summary is in the subject line. ;)

In Spring of 2009, I rewrote the Dojo loader during a requested renovation of that project. The primary pattern used to make it more practical was:

dojo.provide('foo', ['bar1', 'bar2'], function() {

[module code]

});

var containerEl = jessie.getElement('container');
jessie.delegateClassNameListener(containerEl, 'click', 'myClass', function(e, secondParam) {
   // NOTE:
   // 1) Our handler only fires when the anchor with a class of 'myClass' is clicked
   //    or if the img inside the anchor is clicked etc
   // 2) In our handler we provide the raw event object as the first param

   // this could be the anchor or it could be the img so the target in this case is 
   // not consistently going to give us what we want.
   var target = jessie.getEventTarget(e);

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)
