Tachyon3d is a raytracing program that has served Sage very very well

This seems like some nice documentation on the primitives:

It does look nice, I thought the vibration demo:

Hello,
This is alpha7, as you can guess alpha6 wasn't really ready for prime
time. The main problem were little build oddities and some larger
integration issues with ATLAS fixed by Josh Kantor and yours truly.
Additionally I merged a bunch of other, non-ATLAS related fixes by

Hi,
how is the SAGE API reference done? Using docutils?
I am looking for some tool for documenting SymPy and so far I tried:
epydoc, pygment, pudge, apydia and all fail for sympy producing some
error.
So I am curious what your experience with such tools are and what is
your favourite?

Thank you, Michael; I made the change to the copy of 2.8.15 I'd
downloaded here, and that indeed fixes the problem.

I am running Fedora 6 under VMWare. When I compile sage-2.8.15, I
receive the following error. Any suggestions?

What version of gcc is it? I can't build Sage on my Fedora 7 install either
because of a documented compiler

Wouldn't regular expressions be inadequate for deciphering nested
expressions like the following?:

Hi,
This is a (very short!) Sage proposal that we're putting together for
NSF. It's
getting close to being finished. Any comments, including on typos are welcome:

My housemates have been writing a Python wrapper for SVDLIBC (a C library
that does SVDs for sparse and dense matrices over the reals) using Swig. I
