Somewhat related, does anybody know any "beginner material for non-beginners". Pretend I want to learn web development. I have been doing desktop programming and data analysis for many years, so I know all about programming but nothing about how a web-app works. I would be looking for something that explained web apps assuming I know little to nothing about them, but not "how to program" because I don't want to sit through learning about loops or variables. And pretend I'm also the type of person that wants concepts and not just tutorials. Anything like that?
