I did some gooling, because of this thread and of course my own interests being a software dev by carer.
Its a lot of content, but this article on Wikipedia can explain things like using "magic numbers and strings" a hell of a lot better than i can, plus provides explains and documentation to fit.
Really good read if you’re looking at getting into Software Development either has a hobbyist and/or professional
