digitalmars.D.announce - D for BigData: the first BetterC library by Tamediadigital

HyperLogLog++ is advanced cardinality estimation algorithm with 
normal and compressed sparse representations. It can be used to 
estimate approximate number of unique elements in an unordered 

hll-d [1, 2] is written in D. It can be used as betterC library 
without linking with DRuntime. hll-d has C header and C example.

Its implementation is based on Mir Algorithm [3]
   1. mir.ndslice.topology.bitpack is used for arrays composed of 
packed 6bit integers
   2. mir.ndslice.sorting.sort is used for betterC sorting.
