the first guy sucked. i was barely staying awake. not to mention the freezing cold weather.
2nd guy was very informative and charismatic!
3rd guy was friggin funny with those pictures which didn't have much to do with algorithms
though i've seen most of them already. he must be a computer junkie
funny part was the rocket launch picture with the 4 satelittes blowing up. "4 went up, many more came down" LOL.
i recorded the whole 3rd and 4th lecture on my MD
4th lady was pretty confident. had good voice and knew what she was talking about
