Do anyone know what happened? Even the videos from the YouTube channel are gone. His writing and talks very useful reference knowledge.

Very well said. All these points resonate well with my experience.

The two courses that give the basic CS foundation needed are:

nand2teris.org and cs50.net

See if you can solve all the projects & assignments in these courses.

These cover a lot of ground. Once you are done with these two courses end to end, you will get a fair understanding of many of the computing big ideas.

If the student knows almost nothing, these are really good as they cover the most simple things.

If you already programming, they may be too basic.

Yeah I think CS50 is too basic. The C part is interesting though, has some minor projects that worth working on. For anyone who has some programming experience (whatever language), I think CS61A is a better course.

I really wish there is a course that uses C (like first 4-5 classes in CS50) and uses C ONLY and then go as deep as possible, similar to CS61A, but apparently on other topics (one system programming project?)

The problem sets in CS50, at least the first half, are great and I would highly recommend. I ditched it when it moved to python and web, the problems were interesting but there was an added level of boredom in the 'now make it a website' approach.
