Well, the YAPC::Asia 2009 was over a few days ago. I talked on a bug reporting, and gave a few figures in a lightning talk. Here're the links for the slides.
You can check other people's slides from here:
I believe videos will be published later, possibly around the end of this month.
Anyway, I must admit I was very disappointed in a sense, as I felt like I was attending an OSCON, not a YAPC. (If you attended the 2-day main program + dinner + all the 3 courses after that, it costed around $1150 (with a $200 discount applied) :/) However, I really enjoyed chatting/discussing/hanging around with the people, and the sessions I attended were very nice. If you're a web application (framework) developer, you'll be excited by the new PSGI project by miyagawa and others, and the "miyagawanize" by yusukebe was /the/ lightning talk of this YAPC. The purple thing is a small cushion for your chin, which Yahoo! Japan generously gave us as a souvenir for a conference or such several years ago.
