March 27, 2016 Wajdi Ben Saad

In the mean time, ever sense I wrote the first draft for this post, there have been more then a lot of terrorist attacks in Tunisia and the situation in general is getting complicated.

guide them, explain and simplify complex algorithms and technologies that they hear about from the web.
