[commons-math] compatibility of licenses?
Hi,
in project Commons-Math, a contributor recently proposed a patch for
triangular distributions (see MATH-731). One of the methods
implemented is based on a third party Python code, the license of
which is reproduced below. My question is: can I commit this patch?
Should we try and get in touch with the original author (1998!), to
have him sign an ICLA?
Thanks for your advice.

This is actually good to know. Thanks!

This goes without saying.

+1 to Gregs arguing. Legally there is imo no need to add this license, because the work is derivative enough to make it an 'own distinct solution'.
But it's always a good thing to show respect and be thankful by adding something like
"Implementation of the {@link #sample} method is inspired by the triangular distribution implementation of the rv Python module (Release 1.1 27-Nov-98), by Ivan Frohne."
or similar.
It might also be an option for the commons PMC to personally reach out to him, notify him and send him a personal 'thank you'. Maybe he is even interested to help out in other areas as committer in the future ;)

It seems that if the implementation is in Java, then it shares nothing with
the Python code, and (thus) would be independent of any license on that
Python code.
I'll also note that Python 2.6 intruduced a new 'triangle' function into
its 'random' module. Dunno if it is the same thing, but at least that comes
with a defined license (should that matter).
Cheers,
