Hi,
I am personally using a python script to start and stop Sage server.
It uses screen command and is based on the idea William gave below.
Here is the script:

The script reads in the configuration file .sage/sage-server.conf. A

do the same for input? IE, display equations and plots without the

You can get something close to that by putting %hidden at the top of

You can put %hide as the first line of an input cell and this mostly hides

Hello,
In Sage notebook, under the tilte, there are File, Action, Data, sage.
If I scroll down sage, I can see gap, gp, jsmath etc.
I never used this option, but I would like to know what this sage is for.
Thank you.

I have one solution :) very very poor (really very poor) solution
and from this reason I will not supply the patch yet.
The method is to call ode2 again, now together with ic2 in one new
call of Maxima.

Wow, this sounds like a big bug. I will be using Sage quite a bit in a

HI ... I'm scratching my head on this one - anyone know why I'm
getting this in notebook()? Basically the symbolic expressions are
resolved okay, but when it comes time to plot a previously defined
expression, I'm getting this:

I'm trying to run sage matrix operations (ex, solve, eigenvalues,
eigenvectors) on a matrix constant constants variables (variables I've
defined that do not yet have a numeric value), but the ops seem to
either fail, or produce an unreadable amount of latex that jsmath
fails to parse, and I'm

Unfortunately, a lot of stuff with symbolic matrices is now broken
after our switch to using Pynac/Ginac for symbolics. We only just
uncovered a lot of it. In fact, we're not even sure what's all
broken! See http://trac.sagemath.org/sage_trac/ticket/6934 for (a
little) more information. But
William ! Thank you so much for getting back so quick, and thanks for
the work you are doing on this project! Sage is a wonderful wonderful
tool...
I will definitely hold out.
Thanks again!
