How accurately should I store latitude and longitude?
...So let's talk about the equator, where the distance between each degree is 110.574km for latitude and 111.320km for longitude.
50ft is 0.01524km, so:
0.01524 / 110.574 = 1/7255 of a degree of latitude
0.01524 / 111.320 = 1/7304 of a degree of longitude
You need four digits of scale, enough to g...

Why do people say there is modulo bias when using a random number generator?
...8 possible outcomes:
000 = 0, 001 = 1, 010 = 2, 011 = 3
100 = 4, 101 = 5, 110 = 6, 111 = 7
We can reduce the size of the outcome set to exactly 6 by taking the value modulo 6, however this presents the modulo bias problem: 110 yields a 0, and 111 yields a 1. This die is loaded.
