Make attention to use the entropy . The entopy is based on the idea that the amount of information in binary string S is Log(S) , the number of bit to directly code the string . This is wrong , the correct information is the Kolmogorov complexity of S . Nowaday the scientific literature don't focus on this difference and very often use Log(S) instead of K(S) ( K is the Kolmogorov complexity function ) and justify this becouse K(X) is uncomputable and becouse for the major part of K(X) value it is approximable by Log(X) in a mathematical context . This wron...
"So these people are frauds?"
To answer your question , I think the card can be one of the better random generator existing, so it is absolutely not a frauds ( and pheraps I will buy one ... thank you for the link ) . But there are many definition of random . The only one theoretical random definition I accept as true is that a bit string S is random only if this string has K(S) >=Len(S) . My strong deterministic opinion is that in the real world these random objects exist only if we take short object , also for quantum field ( like Wolfram th... (read more)
