[python(x,y)] Python(x,y) 100% free and open source?
Thierry Chappuis
I habe been using Python(x,y) with my students for quite a long time
now. This is a really nice bundle of all what I need in class to perform
chemical engineering simulations using the python programming language
and it makes my life easier in the process of configuring my students'
computer for scientific-oriented tasks. Today, I have discovered another
math-oriented python-based package called Sage. On the website for the
Windows port of Sage (http://windows.sagemath.org/), one can read the
following lines:
"Provide an alternative to Enthought's EPD
<http://www.enthought.com/products/epd.php>, Python(x,y)
<http://www.pythonxy.com>, and ActiveState Python
<http://www.activestate.com/activepython/>:
* 100% free and open source, unlike any of the above systems"
Does it mean that Python(x,y) isn't 100% free and open source? This is
in total disagreement with what can be read on Python)x,y)'s website:
"Python(x,y) est un logiciel libre scientifique de calcul numérique basé
sur le langage Python <http://www.python.org>"
Could someone add a short comment about such license issues?
Best wishes

free version. The Google Code website for python(x,y) currently says
GPLv3, though the actual sources all appear to be GPLv2. Perhaps it's
just a misunderstanding. When I first found python(x,y) on the old
website, I couldn't find the source. However it is available, and I am
trying to help make it more easily accessible for contributions (see
http://groups.google.com/group/pythonxy/browse_thread/thread/932b06f08bb46ae0).
You'll have to wait for Pierre to give his authoritative opinion
though...

It's just 100% outrageous to write that, that's all!
Apparently, they have decided that Python(x,y) is not 100% free and
open-source but I would be curious to know on what basis.

I can confirm that Python(x,y) is a free and open-source scientific
software. Python(x,y) is licensed under the terms of the GPL license
which is... well... (wait for it...) ...an open-source license! (I
hope that Sage people are reading this, they might have learnt
something huge today!! :-)) ).
I remember reading this page on Sage's Windows port website. I'm still
very mad at them: I can't stand people who are claiming such lies so
confidently...

That's right, the source have not always been available online
(because of my old web hosting provider limitations) but that's not a
requirement of the GPL license. The source code must be made available
on demand, that's all and that's what I've been doing every time
someone was interesting in them (my only reluctance to send the code
was related to its very bad quality ;-) ).
