This guy is too old to teach a class, any class. No focus in the lectures, no understanding of what is important in learning a computer language. No understanding of what his students want to learn, no understanding of what he really wants to teach. Amorphous babbling with no direction and sense.I strongly suspect he is doing this class to sell his C++ books. Complete and utter disaster, just avoid this class, and tell other people to not waste their time on this. One of the challenges to MOOC platforms is to weed out these semi-senile Ira Pohls and to prevent them to use the Coursera medium to massage their egos and make a name for themselves. What a shame, it was just embarrassing to witness what I saw. Complete and utter disgust.
