Although I have enjoyed this series overall, I must say I was a little miffed that garbage collection was so blatantly left out of Episode 2. The episode claims to cover memory management, explains that there are two approaches, and then only covers one of them. It says that the “garbage collection road may be easier”, but provides no guidance to starting down that road.
At a minimum, I feel Episode 2 should explain where one should go to find out about garbage collection. For this series to be complete, however, I feel that garbage collection should be covered as completely as was reference counting.
As it stands, it feels like Bill doesn’t understand garbage collection, and so chose to gloss over it rather than admit the hole in his knowledge. I apologize in advance if this is not the case, but that is the impression given.
