Welcome to new academic course 2012-13

First of all, I would like to apologise by the fact of not having opened the blog entried for this academic year yet. We are living the Era of social networking and mobile apps. I would like you to think about these two topics while you read the textbook and feel free to ask me to invite you as a contributor to compose entries in relation to these two topics. Although this book may seem obsolete 20 years after being witten, it state the base of these two basic elements nowadays.
