		<title>Block Attachments in Postfix</title>
		<description><![CDATA[One of our clients requested that we block specific email attachments that come in - their large network was starting to suffer under the storm of non-work emails flying around the office - funny video clips, songs, etc, etc. Not only that, several gullible people had infected their PCs with viruses and malware because they [...]]]></description>

		<title>Set Up Sarg on Ubuntu</title>
		<description><![CDATA[The annoying thing about Ubuntu&#8217;s version of Sarg (the program that generates the usage reports from the Squid logs) is that the cronjobs used to generate the reports are buggy - the weekly and monthly jobs only show some of the days :( Here is how I set Sarg up on client&#8217;s Ubuntu servers. It&#8217;s [...]]]></description>

		<title>Set up Iptables on Ubuntu</title>
		<description><![CDATA[Ubuntu, like any good Linux flavour, comes with Iptables, which is used to filter, route and NAT network traffic. Unfortunately, Ubuntu doesn&#8217;t comes with a way to quickly modify the Iptables rules, like you do with other flavours such as Fedora. This how-to will show you how to set up a script to allow you [...]]]></description>

		<title>The Trick to Gaming AI - Faking Intelligence</title>
		<description><![CDATA[One of the things I really enjoy reading about is artificial intelligence. Not just the academic version, with it&#8217;s pursuit of mimicking real life and creating a true &#8216;thinking AI&#8217;, but the gaming version too.

		<title>Implementing Permalinks - a Basic Overview</title>
		<description><![CDATA[Ever wondered how Wordpress and other CMSes manage to take URLs with querystrings and make them readable (for users and search-engines)? Luckily, there&#8217;s no mystical Voodoo involved, just some basic commands that&#8217;re actually pretty straight-forward. I won&#8217;t be going into great depth mind you, as while the server side of things is pretty straight-forward, the [...]]]></description>
