893 byte source file, python can single-threaded do ~1 million crc32 per second. It's about "10%" done with the AI's version which is nonce = 0 while true nonce +=1 crc32 (data+nonce.to_bytes) which i don't buy will actually cover the whole field, so i'll just repurpose my sha256sum bash script to use cksum and run it again - that puts arbitrary bytes, not arbitrary integers as bytes into the file.

nonces tried: 515000000 nonces tried: 516000000 Collision found with nonce: 1327202703

walltime ~12 minutes. So whoever i replied to (sorry my vision is going blurry so i don't want to breadcrumb back) was correct, modern CPUs just blow through this.

you'll note the nonce is > 2^32. Cute.

This is what AI does. This sort of crap is going to make everything feel slower. except now instead of inefficient humans making inefficient code because "hey, just scale" or "my desktop has 32 threads, why do i care about a 50ms hot loop? one of the other 31 threads can pick up slack" - now it's ... this.

i absolutely cannot believe it chose the absolute most naive way to accomplish this monumentally trivial task.
