I'm currently working with a senior developer whose breadth and depth of technical knowledge is simply incredible. Yesterday he talked for more or less six hours straight, starting with “What exactly does this function do?” from designing compilers, to opcodes and memory management, to the evolution of digital cameras. Listening to this guy is like drinking from a fire hose. And no part of it was rambling. It's just pure, high-density information, presented in a passionate manner. And I've been working with him for weeks now, most days are like the one mentioned above. The funny thing is that this guy spends most of his free time playing retro games and watching anime. I often wonder what it would have been like working with somebody like John von Neumann or how they really see the world.
