I wrote to the "Manager" (Fabian Pedregosa) to update the information.
Just look at the Statistics section (All time, 12 months, 30 days), and look at number of developers, commits, files modified etc. SymPy is clearly more active than Maxima, using these stats. > > It might also help for marketing purposes to increase the SymPy users on Open > Hub... > > (Currently 37 users (SymPy) vs. 54 users (Maxima).) > > - - - > > Ondřej and Aaron: Do you know any citable sources (Blog posts, etc) to > support your standpoint? > I am sure I will find something by myself but maybe not the best (most > convincing). Sure. Google "scientific computing ecosystem", for me, 7 out of the first 10 links mention Python in the title. You can also try other phrases, like "scientific computing community". You get tons of links, e.g.: http://programmers.stackexchange.com/questions/138643/why-is-python-used-for-high-performance-scientific-computing-but-ruby-isnt Specifically, you don't find Lisp (the language Maxima is written in) in those links. Just to clarify: this is to support the claim that Python related tools are the ecosystem of scientific computing. It doesn't follow from this that Maxima is a bad tool (it isn't). It follows, that if you have a tool, written in any language, you better have good Python wrappers/support.
