I'm currently attending the php|tek conference in Chicago. Today is tutorial day, and I delivered a half-day session with Matthew Weier O'Phinney of Zend. Our session was entitled "Practical SVN for PHP Developers" and the slides are online. The session seems to have gone over pretty well - this is my first time delivering a tutorial and overall it was a good experience.
Later in the week I'll deliver two more talks - Linux-Fu for PHP Developers and A Guide to Using and Understanding the Community - plus another in the unconference entitled Architecting Web Services in the unconference. So far I'm meeting old friends and new ones, and having a blast :)
