Yes, but I will never use Udemy. I heard many horror stories, lots of content theft and they take 50% of the income (for most sells).
BaseCS looks great, but has other audience, most ppl I know learn exclusive from videos, not text. And also it has the same issues as the others, there are no real life examples or practical use of the theory.
I have a more unique overview based on my experience and the fact that I study CS, architecture and distributed systems. I can make some correlations between these with examples in a few languages as well.
