I always recommended reading chapters 1-3 and skimming chapter 7 to people who are just getting started with Git.
Joe Kilner - One extra issue with games is that you are outputting an image sampled from a single point in time, whereas a frame of film / TV footage is typically an integration of a set of images over some non-infinitesimal time.
This is something that, once stated, is blatantly obvious to me, but it's something I simply never thought deeply about. What it's saying is that when you render a frame in a game, say the frame at t=1.0 in a game running at 60 FPS, what you're doing is capturing and displaying the visual state of the world at a discrete point in time (i.e. t=1.0). Doing the analogous operation with an analogous physical video camera means you are capturing and compositing the "set of images" between t=1.0 and t=1.016667, because the physical camera doesn't capture a discrete point in time, but rather opens its shutter for 1/60th of a second (0.16667 seconds) and captures for that entire interval. This is why physical cameras have motion blur, but virtual cameras do not (without additional processing, anyway).
This is obvious to anyone with knowledge of 3D graphics or real-world cameras, but it was a cool little revelation for me. In fact, it's sparked my interest enough to start getting more familiar with the subject. I love it when that happens!
I disagree. If passion is an important quality to you, then, as the interviewer, you need to ask questions that reveal whether or not the candidate has that quality. It's absurd to ask about personal projects as a proxy for asking "are you passionate about programming" and then to expect the candidate to guess your true intentions and answer accordingly.
Furthermore, I know that shitting on universities is en vogue, but give me a break. Perhaps you are the one who "did it wrong" and were bored because you chose the wrong university, or the wrong field of study? Or, just maybe, different people learn in different ways?
No shade to DamnInteresting; I find it quite endearing.
