Heh, the commenter was her old Stanford professor, and the link he provided to his website goes to a PDF of his CS249 final exam. Harsh :P

EDIT: notable line from wikipedia article: "Cheriton is also credited for connecting Stanford students Sergey Brin and Larry Page with venture capitalists at Kleiner Perkins, thus becoming one of the early investors that helped get Google off the ground."
From wikipedia: "University of Waterloo announced that Cheriton had donated $25 million to support graduate studies and research", "Cheriton donated $2 million to the University of British Columbia".
