I feel like the class content is a bit unfriendly. Since it is an IT class, most of the time you learn by writing code and following along, but most of the lectures proceed by saying, "The code is like this," and the terminal function is covered by the subtitles, making it difficult to see. I can understand that they proceed by pasting for the convenience of the lecture, but I think it would be better to provide a separate link to check the written code.
