#crc32 — Public Fediverse posts

🎉 BREAKING NEWS: Someone reinvented the wheel... again! 🎉 Meet #Chorba, the "novel" #CRC32 implementation that nobody asked for. 🤦‍♂️ Because what the world truly needs is yet another way to hash data. Bonus points for the riveting "Skip to main content" intro. 😂

The other somewhat more saddening thing is that the idea that a 32-bit cyclic redundancy check value is a good *hashing* value still lingers; 3 decades since the world gradually learned that it wasn't.

The interesting part of that to me, that is unrelated to recent events, is how they *seem* to be reinventing ISC-licenced implementations of CRC32 in 2024. I am certain that such things have existed in the BSDs for decades.

There are probably fully (U.S.) public domain implementations of #CRC32 from the 1990s if one is willing to dig around in the world of old shareware. It was the sort of thing that got posted to magazines or passed around as code snippets in BBSes.
