So...Levent's evaluation of my lecture yesterday? Satisfactory. This coming from him, this must be pretty good. So, not too bad. Now I really have to think hard about how to explain breadth-first search...

I'm now a download freak. Sort of.

I was just trying another one of those difficult sudokus...didn't finish it this time, though. So...maybe later. And I ordered a "super hard sudoku" book as part of the things I bought from the Japanese puzzle website...we'll see if I can do even one of them...
