This last week I flew off to Melbourne for the Open Source Developers Conference. I spoke to many people about a wonderful range of topics. The main things that I was aiming to be across was large or enterprise installations of any CMS that folks have experience with. There are a surprising number of options. Drupal came up many, many times. Varnish with one of Apache + mod_php or Nginx + FastCGI seem to be a common platform.
Although there were a couple of good Perl talks too; Schwern's Perl5i and Damian Conway's talk on Quantum Mechanics + General Relativity + Perl. Reading several of Richard Feynman's books in the last year certainly helped to keep on the same page as Damian as he galloped along with some complex ideas. The talk "git for age 4 and up" was great, certainly cleared up my misconceptions of labels in git =)
