Open Source Convention

OSCon I'm looking forward to the Open Source Convention in Portland next week. I primarily use Microsoft tools for development, so this should be a good overview of what's happening in the land of the free. I have been working with Perl quite a bit lately and I hope to catch some advice from the experts. The conference seems to include a discussion of open systems rather than exclusively "open source" software, and open systems are something I'm very interested in. The Emerging Topics track looks great, especially Bill of Rights for Web Services on Thursday.
