New things

I want to explain to motive because I do not write new things in the blog. I usually write new post when I start a new unit and this unit has interesting thing to write. I do not want that this blog become in an useless thing where I write thing just because. On the other hand, I am making a doctorate in the evenings and my free time is so reduced, then I would like you to be comprehensive if I do not upload the blog so often as I would like.
