Tom, I'm beginning to believe that there is no such thing as Random Data.
But I know the depth at which people here consider data Random so I go by
that. But for the sake of argument, let's call Random data whatever you
believe exhibits the greatest entropy.
There is no trolling going on here, Tom. You disbelieve so you consider
anyone that does believe to be trolling.
The point though is that it doesn't matter if the data is random or
not. messages of length M where M<N cannot represent all possible N-
bit messages. Whether they're random or enumerated. Like a program
that simply emits all 1024-bit integers will need to have at least
1024-bits of storage to represent the counter. Even though the
integers are sequential and totally non-random. So to have a program
that emits all N-bit messages, you'll need either N-bits [or more] of
input, or combine M<N bits of input with bits from the program.
And if you want to emit specific messages than the input must uniquely
determine the output which means you either can't compress all N-bit
messages, or you violate M>N on average.
Tom
Then by your understanding it should be impossible to save 12941 bytes of data from the million bit bin file, correct?
