Programming, not diagramming, is where an engineer actually learns, because code is the point at which you can no longer fool yourself about what you understand.

and I thought programming sitting fingers on keyboard staring at code that's that's where I do my learning because that's where you can no longer fool yourself that you actually understand either you compute the correct value or you don't compute the correct value. So I wanted to elevate that moment of reality meets program and that's where the programming comes from.
