The fourth annual RubyConf will be happening from October 1st until October 3rd. I expect to go and have just submitted by extremely brief proposal for a full-length talk on Rails:
How Rails was grown on a diet of real problems and influences, attracted an audience by being concrete, and still kept a generic core. Will show off the Rails web-framework and discuss implementation details.
Hopefully it'll be accepted. If it does, you'll be able to hear me talk about Rails twice on US soil in the coming months. Starting with The Building of Basecamp in Chicago on September 17th and then RubyConf in Chantilly (Virginia) at some point during October 1-3.
If it's possible, I'll attempt to get a BoF spot at JAOO, too. (Anyone know how?)
