Like most people, I can't be bothered to keep track of wordpress updates, so i've moved the site to use a static site generator (pelican). It's really quite good, and removes alot of the extra crap wordpress adds and needs like a database server. Over the next few days i'll put varnish in front of it so traffic is never an issue to worry about.
I had a few minor issues with all the code blocks on this site, so if you find any issues, email: contact(at)siology.net
