I met Prof. Tanenbaum in 2008, when I pitched AWS (Amazon Web Services) to the university staff. (I was Tech Evangelist for AWS in EMEA at the time).<p>I only knew about him because of his "fights" with Linus Torvalds, and because I've studied on a couple of his books (which I found excellent).<p>Meeting him was a big surprise: extremely funny, friendly, provocative, very smart, and in general someone you could instantly like. I loved when he would think about something and just close one eye, raise the other one to the ceiling, and make one of the funniest faces ever.<p>I felt so happy afterwards, for the honor of meeting him, and for the joy that derived from that attitude of his.<p>I wish every professor was as enjoyable (and competent) as him.
