I am learning to develop in Ruby on Rails. Thanks Mattan Griffel from Grow Hack who's also a teacher on SkillShare [dot] com. He has made a series of 'straight to the point' lectures guiding any person with any level of coding to create a basic version of Pinterest by the use of RoR. The series is called 'One Month Rails' (http://onemonthrails.com). I have been using and I am currently enrolled in his class on Skill Share. Personally I have browsed through hundreds of website looking for learning material and these videos have been the best for me so far!
