For example, sticking to a prime you'll never get 8 bytes the same.

That's all... I don't like arguments from ignorance. As I've said, I don't know why SeaHash uses a prime. Neither do you. Our collective ignorance doesn't imply the designer didn't have a good reason. I can't think of a "good reason" for it either, but that's where we differ: I think "so don't make gratuitous changes" while you think "therefore it can't possibly matter" ;-) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34751> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
