An Assistant Professor of Political Science at the University of Barcelona just sent me an email, telling me that he had taken my Formal Methods tutorial and transformed it into a book, using opensource software and one thing and another. It is just gorgeous! As soon as I finish teaching today, I am going to post it on box.net in addition to the individual chapters, which are in my much less attractive format. What a wonderful thing the internet is! This is like one vast international collaboration. Now if we could only figure out how to take over the economy and run it as a socialist collective. :)
