How We Wrote a Textbook
This looks like a great piece of hard work covering topics that are not easy to grasp. I am wondering why the author(s) chose to write their code samples in Julia. Most algorithm textbooks I have come across use their own "pseudocode" which often ends up being challenging to read, but in a perfect world, I would selfishly like to have all of the code snippets in Python. Even though this textbook doesn't do that (although let's not rule out future optimizations!), the amount of work that went into this was clearly astounding and well done.
