		<description><![CDATA[This is just a quick note on how I was able to get this working under plesk 9, which seems frustratingly limited in its mail filtering ability. Essentially there&#8217;s an option to automatically delete all mails identified as junk &#8211; but nothing to enable you to simply move them into a junk directory (which is [...]]]></description>

		<description><![CDATA[The project I&#8217;m working on currently has many server side java components running on linux. One of these in particular has been experiencing severe memory leaks when running in our production environment (but not UAT, surprisingly!)
It turns out there is a tool provided with sun&#8217;s jdk 1.5 + which will allow you to get a [...]]]></description>

		<description><![CDATA[One great thing about unix is the ability to automate common operations with simple shell scripts &#8211; however there are risks.
One such risk is that in the case a command fails, the script can plough on regardless.
If your script does something like the following..
cp -r mydir backup
rm -rf mydir
..you should really check that the copy [...]]]></description>

		<description><![CDATA[How do you find the files which have been sneakily changed following a release?
The find -newer command can list files which were modified after another file
But I&#8217;m not sure there is a way to pass dates in directly?
The workaround is to create a temporary file with the required date, using touch
eg. for files modified after [...]]]></description>
