This is great. I wonder if anyone would write a 'how to program + CS' book using Julia. Python has a dozen. Julia only has one (Think Julia but this book is just a presentation of syntax and doesn't teach how to program.).

Still, for Linear Algebra, Julia is vastly better than Python in all sorts of ways. A recent Julia book by No Starch press is a good step, but this book, too, is not focused on teaching beginners how to write software.
