I'm looking for a good gift book to give my friend.
he is doing his PHD in computer science and always an A class student since his BSc!
he helped me alot with my degree and i want to get him a good "computing" book but something highly professional that is not easy and boring for someone who has a phd !!
it is hard to decide, but has anyone read a book that he liked very much and learned from it alot?
even like a good book to read before working for example but related to computer science
i know im asking for something hard but maybe someone can help !
Thank you in advance :)
