The lecture content seems good. The text is too small and the lack of code sharing makes learning difficult. Most other lectures and books share code, which is unfortunate. If I can't run the lecture while following it, I have to look at the instructor's code and figure out what I wrote wrong, but I have to go back and look at the lecture every time. In particular, it's especially hard to find the previous lectures. I saw that someone else requested code sharing, but it was difficult because of code leaks... It's hard to agree. Or if the lectures were edited more conveniently... I don't think there would be such requests... It's unfortunate. Still, since this is a necessary lecture, I will persevere and listen diligently.
