Linux – Enable PHP Short Tags
KB ID 0000886 Problem I have a particular web page that uses PHP short tags. Post migration from my old hosting company to a dedicated VPS, this stopped working.

Backing up a Remote Linux Machine With Windows (Using Rsync and Cygwin)
KB ID 0000892 Problem The goal here was for me to get a backup of my VPS server (Running CentOS 6).

Connecting Evolution Mail Client to Exchange 2010 (and Exchange 2007)
KB ID 0000378 Problem Out of the box Evolution can only connect to Exchange 2000 and Exchange 2003, this is because it uses OWA to connect, when Exchange 2007 was released, the way OWA was presented changed a great deal. So if you try and connect to a newer version of Exchange it will error. (Before you email in, I know in 2010, its now called Web App not OWA). But there’s nothing to stop you connecting to Exchange 2007 and...
