Conclusion 

       I have to say that this course has been very hard, because the objectives are a little confuse, but at the same time it has been something interesting, becuase you see and learn things that you have never seen before in your life or especially in your major. The blogg was like a practice of the course, because we had to use the topics that we used in class in the blogg almost every weekend. For me the blogg was something of profit for the course and even for the scores of the course. I have to say that I liked it and I already checked the mistakes in all my entries.
