So far I have spent 90% of my vacation tied to my computer, analyzing gravitational waveforms. Nifty? Sure. But it means not only have I gotten no rest, I have also not had time to start next week's homework, or the end-of-term report for one of the classes, or get my taxes done, or go shopping, or...

In other words, at the end of this week "off" I'm going to be more tired and further behind than I started.

The only other thing I've accomplished, and I use that term extremely loosely, has been to extract the cell phone sounds from Sayonara Zetsubou Sensei for use in my email client.

(Update, 3:21 am: The programs finally finished running, the plots are finally plotted, and I'm going to bed. Unless I decide that's too much effort and I just fall asleep in the desk chair).
