What makes you believe that a C++ library and an interface are not maintainable? After all, Sage is relying on C/C++ libraries. > Other people will join in too.

And developing code with math algorithm requires a mature understanding of the math. That's why I don't believe an undergraduate can develop a CAS from scratch.

Binaries are available from http, if someone is interested, he will make some tests on the binaries and ask me for the source to be available on http.

I never said I would not help you make sympy interoperable with giac. I have always answered your questions when you had problems to compile giac. I would be happy to have a python frontend to giac and I'm ready to help you if you are willing to. Moreover, this is not the same situation, giac (as maxima or axiom) was here before sympy and sage. > Well, my experience with Sage developers is that they are > extremely helpful with helping these efforts and answer all questions > I might have. > Did you try to send or do some patch?

It would be a waste of time, because I don't know python (and learning python to a fluent level certainly requires some time), I don't know exactly what to do and I would not have a reasonable insurance that my library would be integrated in the sage distribution. > > Well, you know what Linus says[1], right. :) If it was that easy as you say, > someone would already did it. > Nobody says it's easy. I just can't see how it could be easier to redevelop all from scratch. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
