Show HN: Hackers.tv – Tutorial Videos for Beginners

Hey everyone, i was working on this days in www.Hackers.tv the idea is to collect the best Tutorial for Beginners, i am looking for really good tutorials, could you recommend anyone?

I built this because i am trying to learn for myself and many of the tutorials are paid tutorials on Udemy, Lynda and others... and the only way to find the free ones is searching on Youtube. Thanks for your feedback!
