"More like a live coding class than a lecture" Most people have probably taken classes from professional instructors or teachers. It is hard to expect well-organized class progress, abundant materials, etc. from this lecture. However, I think it is a good lecture for those who can acquire it by thinking about the topic, researching it, and doing it themselves. I was able to allocate additional time because I am a student, but I think busy people might not like the lecture progress. However, the lecture you uploaded recently seems to have improved this problem. Since it is an old lecture, please take this into consideration when choosing it.
