Sorry, but information or entropy is not lost, its a bijection, I will soon add the inversion.

  I'm not claiming to be the world's leading expert on UUIDs but you must be loosing something somewhere ? If its not entropy, you must be opening yourself up to collisions or something ?

    Why ? It looks like those ShakespeareIDs (SIDs) are much longer than UUIDs. So I am not sure how you reach the conclusion than the count of possible SIDs is smaller than UUIDs. The author mentions its a bijection, meaning for every UUID you can generate its corresponding SID and vice versa. This, in turn, means there is no higher probability of collision in the SID space than in the UUID one.

      True

        Forgive me if I’m misunderstanding something, but these aren’t UUIDs, but a SID that maps to a UUID?

    No, I can prove it mathematically, it's an easy bijection exercise.
