The text book
I would encourage you to get your hands on a copy of the text book (see admin page for a link to the book) as soon as possibly. The same book is used in IT3010 and TDT39. I know Academia does not have any copies stocked, which is partly my fault because I did not inform them that we will use this book in the course. But Amazon has it, and I am sure some of the students from last year are willing to sell their copies. This is a good book that you will enjoy using it also when you do your master thesis and later on in your professional life.
