Seeing as I’ve never been to one (yet) I can’t really have a favourite. However, I’ve been to the National Computer Science School (ie computer camp) and it was possibly the most fun I’ve ever had in my life. A week of writing scripts in Python, having access to powerful computers and a fast Internet connection, and most importantly, making friends.
During the week we had to write a search engine spider as part of a website we built for a charity. My fondest memory of the week is, along with my good friend Michael Wheeler, modifying the spider and setting it to work downloading as much of the Internet as we could before Python crashed. It took a while.
I’m looking forward to attending linux.conf.au (named after its domain name) in Brisbane in January 2011. It should be a blast.
