What exactly were you calculating?

I was calculating the optimal parameters for bloom filters, a space-efficient probabilistic data structure. At RSA, we develop software products for security operations centre (SOC) that parse, index and query petabytes of security events. We use bloom filters to speed up queries in the querying engine of these products while occupying less storage space than a traditional inverted index.
