Introduction to Programming: What I wish I knew

Every Introduction to Programming class starts with a programming language, introduces various concepts like variables and functions and leaves with an understanding of some simple algorithms. Mine was no different. We used C and spent a lot of time trying to make students comfortable using Linux. This leaves a lot to be desired. Software engineering is hard and laying out certain principles at the beginning can help tremendously. This is a short list of supplemental resources I would have liked to have when I started programming.
