MurmurHash on Github no longer MIT for commercial use? #63

Open SOesterreicher opened 6 years ago

SOesterreicher commented 6 years ago

Hello,

MurmurHash2 on the webpage: https://sites.google.com/site/murmurhash/ has the following license information: All code is released to the public domain. For business purposes, Murmurhash is under the MIT license.

On github here I can find the following license information: SMHasher is released under the MIT license. All MurmurHash versions are public domain software, and the author disclaims all copyright to their code.

Question: Is MurmurHash on github no longer MIT for business purposes ? Or was this part forgotten during migration?

Thanks in advance Siegfried Oesterreicher

Wiki says it still MIT.

SOesterreicher commented 5 years ago

Thanks for the information.

I still have doubts because the wiki page https://sites.google.com/site/murmurhash/ clearly states at the top: "this page is deprecated". Therefore I can't trust this page anymore.

On the github wiki https://github.com/aappleby/smhasher/wiki and the Readme.md https://github.com/aappleby/smhasher states the license information: "SMHasher is released under the MIT license. All MurmurHash versions are public domain software, and the author disclaims all copyright to their code."

I was not able to find on the current github repository the MurmurHash MIT license information for business purposes.

Based on this it seems the possibility to use MurmurHash under MIT for business purposes is gone.

Is there a possibility to get a statement from the author?

Thanks in advance. Siegfried Oesterreicher

Any news about the missing MIT statement on the github main page? Thanks in advance. Siegfried Oesterreicher

@SOesterreicher

The licence in the code also attempts to put the code in the public domain: https://github.com/aappleby/smhasher/blob/master/src/MurmurHash3.cpp#L3

This being the more recent publication, it takes precedence over whatever the old website says.

(Although technically in some countries it's not actually possible to relinquish copyright, so this statement might not be lawful in those countries.)

Hello Pharap, Thanks for you view. Your statement in brackets is the point why I opened the issue. Especially that there was an MIT license for Commercial usage which seems to be removed.

Hello aappleby, as you are currently working on the aappleby/MetroBoy repositroy, can you please have a look into this issue of the removed MIT license.

Thanks in advance. Siegfried Oesterreicher
