schliz writes "Australia's UBank has put a billion real-world transaction records behind a website that allows users to compare their spending habits with others of the same gender, in the same age/income range, neighborhood and living situation. The 'PeopleLikeU' tool surfaces favorite shops and restaurants surprisingly accurately — because it's based on real customers' transactions, it lists places like good takeout joints that wouldn't normally come to mind when you think of a favorite place to eat. The bank says all data was 'deidentified' and it consulted with privacy authorities."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
