comment Contiguous edges of a cube (and other regular solids)
@bof I left out the dodecahedron due to lazy thinking. And yes, I was referring to a 4-dimensional hypercube. You are right that the octahedron is fully traversible; just didn't find the right path before.

Have the students watch Vi Hart's "How I feel about logarithms".

comment Calculating capacity: number of servers needed for various probability levels
Thanks for the insight. FWIW the company has an enterprise account spending obscene amounts with Google for search support; the XML API is what we'll likely be using. Now...given those distributions, any answer to the question for the formula itself? ;)

A nice answer; I note that you don't include the case of a=1 exactly. :)
