The topics covered are (mostly) adjacent to things covered in this book (with the exception of version control), but it seems like an excellent way to bone up on skills like how to work with the command line, how to accomplish basic tasks at the command line, and various other things that students tend to struggle with but that we don't usually have time to go over in class in great detail.
