“The problem is that coding isn’t fun if all you can do is call things out of a library, if you can’t write the library yourself. If the job of coding is just to be finding the right combination of parameters, that does fairly obvious things, then who’d want to go into this as a career?

There’s this overemphasis on reusable software where you never get to open up the box and see what’s inside the box. It’s nice to have these black boxes but, almost always, if you can look inside the box you can improve it and make it work better once you know what’s inside the box. Instead people make these closed wrappers around everything and present the closure to the programmers of the world, and the programmers of the world aren’t allowed to diddle with that. All they’re able to do is assemble the parts. And so you remember that when you call this subroutine you put x0, y0, x1, y1 but when you call this subroutine it’s x0, y0, x1, y1. You get that right, and that’s your job.” — Donald Knuth в интервью для «Coders at work»
