It is raining in Japan. They told me it would be the rainy season while I was here, but it was sunny up until now. I even got a little sunburn on Sunday.

This is a working trip in Tsukuba. The whole time I have been stuck on one single awful problem with some code I wrote. I might as well be slamming my forehead against American brick as Japanese concrete. I haven't even begun to prepare for tomorrow's dog-and-pony show, my seminar.

I am cranky. I was spoiled by 3 days of vacation and sightseeing. Now I'm back staring dumbly at my many emacs windows hoping some solution will jump out from one of them, releasing me from this prison of anxiety. I hate being stuck.
