Hi, I spent last couple days figuring out how to get mayavi2 installed into Sage, using offscreen rendering (e.g. so that you can use mayavi from ipython over ssh, without X), so that it can be used in the notebook easily. It was a lot of pain, so here is the howto so that you can build on my wor

Hi David, Alex Ghitza and I ran into something similar to when I was reviewing #4762; I thought we fixed it, but maybe it was a different segfault? In any event, the problem is that there are two different classes that sometimes get used for 2x2 integer matrices: matrix_integer_dense and matrix_

Hi all, Maybe it is time for Sage to drop its ban on GPL3 code? After all there is the lawsuit of Microsoft against TomTom. If Microsoft does not behave nicely with people using open source software there is zero reason to be nice to them. Michel --~--~-~--~~~---~-
