The class moved by really quickly. while I was there, I was playing with cygwin, which works a whole lot better then it did about 6 months ago when I last played with it. The only thing I was really using on it was ssh at the class, but I'm sure there are many useful things that I could have been using with it, had I just thought about it.
practicing rolling that ball on my hands now. I'm doing quite will for two weeks of practice. :) My left hand still needs work, though.
