python-bloomfilter 2.0-1 (armhf binary) in ubuntu cosmic

 This module includes both the Bloom filter probabilistic data structure,
 together with a Scalable Bloom filter that allows a bloom filter to grow
 without knowing the original set size.
 .
 Bloom filters are great if you understand what amount of bits you need to set
 aside early to store your entire set. Scalable Bloom Filters allow your bloom
 filter bits to grow as a function of false positive probability and size.
