Discuss choice of license

[xresende]

What license do we really want?!
MIT vs GPL ? Other?
We never discussed this issue.

@xresende, in my opinion the answer to this question does not depend on our opinion 😁.
This code is a property of the laboratory, isn't it? We need to know what LNLS recommends, don't we?
Actually, I think the same is valid for all lnls-fac codes...
I hope they choose MIT 😅 .

From http://www.gnu.org/software/gsl/:

If I wanted to distribute an application which uses GSL, what license would I need to use?
The GNU General Public License (GPL).

This means trackcpp has to be under GPL as well, and I believe this propagates to all other code which uses pyaccel, such as sirius and va. An alternative to the GPL is LAPACK (http://www.netlib.org/lapack/index.html).

A nice source of information on licensing is http://choosealicense.com/.

@fernandohds564, I checked. Here's what I understand:

In Brazil, since 1998, the employer does have the right to software developed by its employees hired specifically for this purpose. This new ( 😂) law (http://www.planalto.gov.br/ccivil_03/Leis/L9609.htm) changed the previous one from 73 in which the employee had half the rights.

But, as always in life, the discussion is not that black-and-white, apparently. Look at

If I could I would wave any eventual software right and accept whatever license CNPEM/LNLS chooses for the Sirius software that I am helping to develop.

Since I love symmetry I have to end with this: I hope they choose GPL 😅 .

So, what do we do? Do we ask CNPEM/LNLS for recommendations? If so, to whom do we ask?

[xresende]

@afonsoharuo, I understand. But:

To use MIT's licence we would have to abandon GSL. Other than what CNPEM/LNLS has to say on the matter, why MIT's would be preferable over GPL?

Ximenes.

[xresende]

@afonsoharuo, it is naturally no pressing matter but we could discuss this issue with people over coffee breaks. Zé is the person who comes to mind, for example.

[fernandohds564]

The point is: what if CNPEM/LNLS decides we cannot use either GPL or MIT?

[fernandohds564]

Yes. Or, maybe, Cleonice...

[xresende]

We may then have to give up GitHub since we may not distribute our software, dependig on the license. (I suppose using GitHub means distributing...)
