I am a first year student of informatic engineering in Italy. Because books are expensive a lot of student just pick the book in library and then photocopy it. We also have a shared dropbox folder where everyone can upload a pdf book so it's available for everyone. I can't post link and i don't even know if the link to this material can be posted in the download section, so I am just asking you if the link to this material can be posted here. I just want to contribute a little bit. PS The language of the book is for the 80% in english. Yes, I read the Rules but i don't want to be banned.
