I'm also headed to Rails Conf this year and I might be speaking at OSCon on extending Ruby and Rails with C code.
This will be a busy year, but I'm looking forward to catching up with all my No Fluff friends and meeting the attendees at the conferences. You get a great crowd when people are willing to give up their weekend to learn.
I'm also doing a really fast overview of Ship It! called Shippers Unite. I'm planning on rolling this talk, with some of the others, into some training classes related to implementing the Ship It style of software development. I've a number of people ask about onsite training of this type and this is the year I'll be rolling that out. I'm planning on a two or three day class. Drop me a line if you're interested and let me know what parts you'd be most interested in learning.
