Here's what Microsoft are doing at OOPSLA this year: http://msdn.microsoft.com/architecture/community/events/oopsla2004/
Network connections permitting, I'll be blogging for the couple of days I'm there.
OOPSLA will be an interesting experience for me this year. In the past I've attended and presented as a researcher from the academic community. I wonder if the experience will be any different now I'm on the other side of the fence. It will also be a great opportunity to meet up with old friends - especially since I was unable to make the UML conference, the first time I've missed it since its inception.
And watch out for those announcements around software factories and domain specific languages...
