The practice session was followed by Q&A about the judging system, and then a talk by Bill Poucher which announced several nice things: they're considering adding Python to the next year's available languages, and they're considering making the spot allocation system for the World Finals public and known in advance.
Tomorrow's competition will be broadcast with commentary at http://icpclive.com/ (more details in this Codeforces post), but I will still try to share my own thoughts via live commentary on this blog. Check back tomorrow!
UPDATE. According to this post, there will be an opportunity to solve the World Finals problems during the contest. In that case, I will be participating together with tourist and meret, and the commentary here will be mostly about our team's work.
