An algorithm is a sequence of steps to be followed to accomplish a certain task. Often used in computer programming, they can become interesting puzzles because even though there can be many ways to accomplish something, one may be better than another.

1. Devise an algorithm to generate uniformly distributed points on the surface of a sphere (i.e., so that no area has a higher expected concentration than any other of the same size). Positions can be referenced by latitude and longitude.

2. Say an event happens at 60 times per hour in a Poisson distribution (say customer arrivals in a store), so averaging also once per minute. Devise an algorithm to generate realistic arrival times for a one-hour period.

Note: Assume what's available is a uniformly distributed random real number generator on the interval (0,1).
