The counting zeroes in "100!" problem is actually a common high school level math contest problem. You're supposed to calculate it by hand, not with code. The trick was to notice - number of trailing zeros is equal to times y

I think might have been Google who said this, but you should design for 100x of your expected load and when you get within 10x you redesign and rewrite it. It will make sure you don't try to design for a billion users when you have a t

I think you're right that the barrier is a lot lower now that there is a somewhat successful blackbox abstraction. In the past you need to know that to recognize lines: hough transform, recognize polygons: line simplification, recogniz
