in thread What data is code?

(length(compress($text)) < 0.8*length($text))

Is the magic number "0.8" coming from intuition/experience/choice of an example?

Or do you have some reference or pointers for that threshold (not that I expect this in such an answer, it would just be nice to know where it comes from)?

    I just wanted to pick a number between what I expected to see with normal text and encrypted. Theoretically there should be no compression. Realistically people "encrypt" things with xor, and then you will be able to get some compression, just not very much.

    Fixed typo that mkmcconn caught, and thinko that blakem pointed out.
