Agreed. Pretty much asking for an intervention. Practically begging for a crackdown. Larger plan?

When private organizations are regulating the speech of the population? It's a necessary slope. Because doing it without centralized government control is bad. But regulation of speech can be good. Take a look at https://www

you need others to not make crypto claims, but you're so sure making your crypto claim that it's not cryptographic. it's always easy to front as an expert spectator and believe others work is no good. why don't you back

Can you break this? If no, so your claim is basically hot air, is that right?

well I've got a crazy theory for you, then. I actually think there's something like a black hole inside nearly every Star. Not just a dark core. But a region of emptiness. BTW would it be possible to have an antimatter star? Like

Can you break 128-bits? How should I say it?

No probs. I think your idea of unifying the two loops is a good one. A new version that uses the idea and overcomes the challenges would be great, and would simplify the code even more. If you had a way to make a start on it, I welcome your

No because I think that library is for encryption. This is for hashing.

Great question, and thank you, Salvatore! Some reasons for that are: different hashes for s and s\0 (without explicitly using length) to make it harder to create collisions, related to as you say better distribution/avalanche for short

Thank you, Austin! BTW, not sure exactly what you mean by cross-half mixing, but I'm assuming it means mixing both halves of the 128 bit state with each other. There is that, on 3 lines 91[0], 100 and 108. The 128 bit mix, stirs tw

> DiscoHash is included in SMHASHER [3] but its benchmark results aren't. They are included, but understandably you missed them because it's also called BEBB4185, stated in README. Find BEBB4185 line in SMHASHER Readme. Good

Simple hash, 128-bit mixing function is just: mix(const int A) { const int B = A+1; ds[A] *= P; ds[A] = rot(ds[A], 23); ds[A] *= Q; ds[B] ^= ds[A]; ds[B] *= P; ds[B] = rot(ds[
