Allen Downey (author of the above) has a number of books on computer science-y things. You can buy hardcopies but I think all of them are also just freely available.

Here's a few:

Think Complexity

Think DSP

Think Stats

Think Bayes

You missed How to Think Like a Computer Scientist.

Many places on the web. Runestone is probably the most useful like but I’ll leave my favorite classic one below.
