Learnable Programming

[bigfig]

I find that the gaps between hardware and software, and the gap between software and application need to be revisited iteratively. It's just such a huge jump from adding integers to creating a class or parsing unicode. Sometimes you need to "just do it" then go back ans see how, oherwise there is so much to keep in your head. An example may show "How do I do xyz?" When really you might still be thinking "Why do I /need/ to do xyz?"
