The example shows how to get the first array element on three different ways.

<ul>
  <li></li>
  <li></li>
  <li></li>
</ul>

<script type="text/javascript">
    $(document).ready(function(){
        var elems, elem;
        elems = $("li"); // get an array of all the list items

        // This is a jQuery object that you can call jQuery related methods on.
        elem = elems.eq(0); 

        // This is the DOM element itself that lets you access the native
        // javascript attributes and methods.
        elem = elems.get(0); 

        // This is the DOM element too.
        elem = elems[0];
    });
</script>

Instead of using the filter method eq() you can combine the filter with the selector like this

var elem = $("li:eq(0)");

or

var elem = $("li:first");

To turn a DOM element into a jQuery object you can wrap it with jQuery(element) or $(element) if you’re not in conflict mode. But keep in mind that this creates a new object which wastes consumes memory so pay attention if you do this in a loop.

A hacker named Kirllos has a rare deal for anyone who wants to spam, steal or scam on Facebook: an unprecedented number of user accounts offered at rock-bottom prices.

Researchers at VeriSign’s iDefense group recently spotted Kirllos selling Facebook user names and passwords in an underground hacker forum, but what really caught their attention was the volume of credentials he had for sale: 1.5 million accounts.

public class Dummy1
{
	private class Dummy2
	{
		public Dummy2()
		{
			method();
		}
	}

	private void method() { }
}

So far so good but if the inner class has the same method this will be called instead. To avoid this ambiguity one can call the method in a more specific way. To be able to call the method of the outer class the prefix Dummy1.this can be added.

public class Dummy1
{
	private class Dummy2
	{
		public Dummy2()
		{
			Dummy1.this.method();
		}

		private void method() { }
	}

	private void method() { }
}

Once again I have some trouble with my backup drive today. The problem is that at any time the connection to my external hard drive gets interrupted. This is very bad if Time Machine, the backup software, is writing to the disk at the same time and there’s absolutely no rule when this appears. One more bad thing is that the system recognizes the lost connection but it hangs up until the cable is unplugged. It looks like the hard drive is going into a sleep mode but you can still hear the disk rotating. There’s a WD Caviar Green inside and after my research I’m sure that the case is the evildoer. This is a MacPower Pleiades 3.5″ FW400/USB I bought in last August.

These and those have the same problem with their Pleiades case and here’s a video of a guy getting nervous like me:
