I've safely landed to Brazil, ready for tomorrow's hackathon with fglock++. On Thursday cmarcelo++ will join us, so it'll be an excellent chance to get the new generations of Perl 5 and Haskell runtimes rolling again.
Another good news is that I've finally recovered a bit from rapidly shifting time zones, so I'll start retro-journaling about the U.S. part of this strange and wonderful journey.
However, the sad news is TimToady++ will not join the hackathoners as expected -- he was feeling a bit under the weather, and had to cancel the Brazil trip. :-/
As an unexpected consequence, I'm now charged, as the TimToady++ surrogate, to give the opening talk on Optimizing for Fun, which put me immediately into omg-I-have-no-slides-must-JIT mode.
Fortunately, geoffb++ had summarized the fun-for-Hackers side pretty well, and the fun-for-Users side is also well covered by kathysierra++ (Creating Passionate Users) and raphpkoster++ (The Theory of Fun); all I need to do is threading them under a metaphoric theme, as TimToady++ did in his previous State of the Onion talks, namely Evolution, Semiotics, Chemistry, Music, Perl 6 (ok, that one wasn't metaphoric), Scientific American, Impossible Objects, Screen Savers, Espionage, and Families.
