This is just a crude PoC!
dakami_rng.ff100k <- 100k "random" bytes generated by dakami_rng.html
in a Firefox 24.0 running on Linux
Output.txt <- dakami_rng.rb used on dakami_rng.ff100k
Observe that the number of occurrences of a given "random" byte
somehow correlates to the Hamming weight of that byte.
For further background on this see [0].
Cheers to Dan!
