Actually, I think you were emailing me about this one: http://code.google.com/p/sympy/issues/detail?id=1031 I started fixing it at euroscipy, but got distracted by other things, I even forgot to report it. So I created the issue now and then was curious how much time I need to fix it. As you can see from the issue, it took me exactly 18 minutes and the patch is just a few lines here and there (basically just implementing a series expansion for the floor function). But anyway, those are things that anyone can easily fix, so my own highest priority is to make sympy a lot faster, so that it is competitive with mathematica in terms of speed. As Linus says, the program needs to do 90% of the job for most people, only then people will start fixing the rest 10%.
