Hi, in a moment of procrastination I came up with this: https://www.sagenb.org/home/pub/1728/ Hopefully somebody can put this banality to good use within SAGE :) Best, -- Hector --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.c

One other thing that I think is relevant in a situation like this: software like Mathematica will have a major economic damping factor applied to its growth, so that after it reaches a large number of users, it will effectively saturate its market (since others can't pay for it) sage will be limi

Since they are still in that rc I should mention a couple of typos that I spotted in two spkg. In linbox in the spkg-install file on line 41 we have an interesting reference to ${SAGE_LCOAL}. In sage-2.10.3.rc3 in the top setup.py at line 430 we have: define_macros = [('GSL_DISABLE_DEPRECAED','1')

I agree; I'm not sure 10^6 users is a useful goal to have, although I am not against it. One of my hopes/goals for Sage is to make every mathematics researcher and educator aware of its existence, and for it to be useful to a large fraction of those folks. Accomplishing that would result in rou

The mathematica one has a nice egg shape, which I think is surprisingly hard to get right. It uses the implicit surface x^2/4*(1 + 0.1 z) + y^2/4*(1 + 0.1 z) + z^2/2.75^2 = 1 so I can tweak your code for an improvement in shape: var('s,t') g(s) = abs(sin(1-s)+0.01*sin(2*(1-s))) g(s) = ((0.5749
