You should probably look into the rsync utility. It will do intelligent directory transfers across machines.

I would recommend doing a whois query.

I'm reading the Effective C++ collection

Start with a valid board. You can pick two numbers at random and swap all of those numbers on the board. Repeat until happy. The trick is removing numbers so that there is only one solution.

edit: i should add, that of all the methods listed in this thread, mine is the only one that is incapable of generating an invalid sudoku arrangement. all of the others will involve a guess and check when attempting to fill the board, as well as a fair amount of back tracking.

I think all of us were using a whitespace ignoring character counter. I put yours into one and it gets 75 characters.
