Example (short audio clip):
And I stress this point because I will get programmers tell me that they're fine with one-dimensional arrays and maybe they get two, but beyond that they think it gets kind of weird and geeky and esoteric and maybe you need some kind of special mental clockwork to deal with it all. And you don't, and you're doing yourself a disservice to think that way. Because if you understand the idea of a phone bill for a cell phone family plan, you already understand the idea of a multidimensional data structure and why we need one. Okay, you might not have the syntax down cold, but syntax can go hang. We can deal with that later. It's the concept that comes first.
What do you think that means?
