					<description><![CDATA[A few years ago I wrote a simple but handy Mac app that calculates unix file permissions using a matrix of check boxes. I wrote it because I wanted to better understand how those octal values get calculated and to expand my experience of writing Mac apps. I was also learning some crazy assembly code [&#8230;]]]></description>

					<description><![CDATA[Fabrice Bellard has written an impressive PC emulator that actually emulates a PC with a 32 bit x86 compatible CPU. This is some really imaginative use of pure JavaScript which I&#8217;m sure no-one would have every dreamed of as it allows you to run a virtual instance of Linux inside a browser window!

					<description><![CDATA[With the PHP mail() function, you can specify additional headers for the emails that you send.
