Ask HN: EdX Experience

I took about 80% of the Introduction of K8S without certificate. The content is brief, very brief, or you can say that it is shallow in terms of details. But I found it very informative for bootstrapping the first steps if you know nothing about that field. The big picture is pretty clear, clear enough for you to digest other real resources or materials.

Fundamental courses might be solid. I once scanned some courses like Signal Processing and I think one can real learn the subject from the course.
