The story goes that 4 NYC students were inspired by a speech by Columbia University law professor Eben Moglen, who stated that centralized social networks were &#8220;spying for free&#8221;. The four then used [...]]]></description>

It even says that you can set the width to be the same as the current width and gives the example below

Of course, it&#8217;s a catch 22 situation: the more HTML5 compliant your browser is, the more you&#8217;ll enjoy the presentation (which encompasses HTML5, CSS3 and the new JS APIs). They should do a video of it showing what it should look like so [...]]]></description>

		<description><![CDATA[A few years ago, it seemed that web developers had to code their websites in two ways: to be compliant with standards and newer browsers, and for backward compatibility with IE6. Yes, IE6 was still widely used and behaved in its own manner, not following many CSS, JavaScript and HTML standards. This meant web developers [...]]]></description>

		<description><![CDATA[Several web apps, such as Virgin Broadband activation, require you to have a &#8220;Windows or Mac&#8221; computer. Most of them only check the useragent string that your browser sends them so you can do the following to fool them:
1. Open firefox and type about:config in the address bar.
2. Type in general.useragent.extra.firefox in the filter bar.
