By the way, the sheer inefficiency of that searching algorithm (ie. what you are complaining about) is _precisely_ one of the reasons why quantum computers are so interesting (the other reason is the number factorization into primes). But that's going a bit off-topic, I guess... ;-) Best, :-) Marko -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
