In any form of hash function, cryptography field, or information warfare, five years is an enormous length of time.
That means "somebody" in humanity has been brute force algorithm generating improved integer hash functions for the last half decade.
For all I know, Google, NVidia, Microsoft, NSA, Spetssvyaz, 3PLA, and Unit 8200 may have been in an integer hash function generation arms race for the last half decade.
Long Reuters article today on drones, and how the US is floundering (they're just not spending as much money as people want). [1] However, if drone can dodge better than enemy can shoot drone, then integer hash function is suddenly not "civilian". Missiles have known this forever. Talk to the MIRV industry.
The big ones probably not, but I extended and ran my fast-hash generator just this year again, with new ideas and new builtin op codes, and the results didn't change since at all. You need to find a combination of fast and good-enough hashes.
But fast string search changed a lot in the last decade. The previous winners were all taken over by a new two-way algorithm as implemented in musl. This was a surprise. search is definitely more important than inthash. Maybe glibc will catchup in the next decade.
String hashing also got much better since. This is terrible forever in all stdlibs.
I didn't get an answer at 800-I-AM-MIRV, and don't know another way to contact this industry. Can you perhaps instead hint why you think that this industry might imply that non-cryptographic hashes are not "civilian"?
Is that a bad thing?
