This document discusses several topics including which option is greener, who knew something first, the power of big data, differential privacy, and a joke about binary. It cites two sources, one from 2011 on human mobility and social ties and another from 2006 on differential privacy in databases. The document compares option A and option B, and discusses differential privacy as randomized functions giving privacy if datasets differ on one element or less.

“A randomized function K gives –differential
privacy if for all data sets D1 and D2 differing
on at most one element, and all S ⊆ Range(K),
where the probability space in each case is
over the coin flips of the mechanism K.”
