Sage includes a couple of different linear programming solvers, which
may be relevant - cvxopt, cddlib, and I think Nathan Cohen added GLPK
as an optional package. I'm not sure how well they could be
integrated into the symbolics, I suppose adding support for what
maxima can do might be the easie

Maybe I'm wrong, but I don't think the range is nearly as important as
the type of function. Some functions won't require many plot

With CC or CXX unset (so they default to gcc and g++), c_lib in the Sage
library, compiles C code with gcc, then switches to using the Sun compiler
(/opt/SUNSwpro/bin/CC) for compiling C++ code. See below. (If the Sun compiler
is not installed, it will use g++).

They are almost entirely different projects. I think the Sage
notebook overal has far more features (e.g., @interact, 3d plotting
integration, tinymc
Apart form the readline issue, I also had to symlink
/usr/lib/crt1.o, /usr/lib/crti.o and /usr/lib/crtn.o to /lib

The sage build was failing on some Fortran file before that:

You have to use finer mesh / more points in such cases
u = var('u')
parametric_plot3d( (u*sin(u), u*cos(u), u), (u, 0,
100),plot_points=500,viewer='tachyon')
(I tested it with viewer tachyon since I do not have java on current
machine)
Hope this helps

OK, so ,there is the plot_points option, but shouldn't the default
value of the plot_point be a function of the range?
Anyway, it's not a big deal for me, but maybe for my Calc students :)

How is it now managed? By using trac directly?

I don't understand: which is the difference between this codenode and

notebooks at the precisely same moment? This would be good in some
sense, but also bad, if you know what I mean for avoiding waste of

I've never used the LiE package myself, but I've heard of other people
using it. I'm cc-ing sage-devel which is probably a better audience.
I'd just post your code anywhere, and would guess if/when someone
finds it useful it would be a good start for a sage .spkg.
