Hello,
Sorry I didn't get in on this sooner -- I've been really busy with
things this past week. Anwyays, CombinatorialAlgebra is getting a bit
of an update, and the changes are on the sage-combinat patch
repository. You can see a working group ring here:

Dear Sage support:
Hilbert's Nullstellensatz states that a system of polynomial
equations f_1(x) = 0,..., f_s (x) = 0, where f_i in K[x_1,..., x_n ]
and K is an algebraically closed field, has no solution in K^n if and
only if there exist polynomials a_1,..., a_s in K[x_1,..., x_n ] such

This is a more general question: should Sage or other large systems
use the Mac frameworks on Macs? Or more generally, shared libraries
on other systems/distros?
I ask because I recently downloaded GRASS, a large GIS system.

Good catch. Maybe the documentation should be updated to use
p.show(aspect_ratio=1) ?

The first example here:
http://www.sagemath.org/doc/html/tut/node21.html
.. shows creating a circle plot via:
L = [[cos(pi*i/100),sin(pi*i/100)] for i in range(200)]
p = polygon(L, rgbcolor=(1,1,0))
p.save() ## or p.show()
When I try this, I get an ellipse! Or more precisely, the plot
I don't use the vmware version, but you should be able to save sws
files somewhere else on your system as a backup, from the notebook.

A huge dissatisfier for the third time ..
I update VMARE (to version 2.04) and thereafter SAGE (from 3.0 to
3.0.3).
This is the third time I lost all my notebook files (sws) ...
How can this be avoided!! Please help, because many days of work are
now 'lost'.
Thanks in advance. Roland
