Isn't that the point? That hashing maps an arbitrary set of numbers to an approximately uniform scale-invariant distribution.

- jallmann 14y agoThat's not what I said. Generating a predictable distribution by hashing is old hat. What's awesome is you can then make inferences about the original data from those hashes -- something that good hash functions are supposed to be resistant to, in isolation.
- shardling 14y agoIt works here because we only care whether two bits of data are equal -- and a hash function had better preserve that relationship!
