Hi:
I have an old 64 bit machine with 64bit ubuntu fiesty fawn loaded on it.
I just noticed a problem with plot3d on it (plot3d runs fine on my
intel macbook):
In sage 2.9.3:
sage: x = var("x")
sage: y = var("y")
sage: p = plot3d(x^2-y^2,(-1,1),(-1,1))

Hi Robert,
1. Is this a clean, from-source build of sage-2.9.3?
Yes, i tried it out on two different systems now, Athlon XP, and Core Duo,
both running on Debian Etch, and both show the same behaviour
2. What is the output of /usr/bin/env for you? Mine (Intel OS X

Georg,
1. Is this a clean, from-source build of sage-2.9.3?
2. What is the output of /usr/bin/env for you? Mine (Intel OS X
10.5.1) doesn't mention sage at all, although mysteriously things are
working for me.

For me, I get

Thanks for the hints. I did look at "Dive into..." a while back (it
is recommended on the Sage website after all) but for some reason did
not get on with it (the very frist "complete, working Python program"
just left me cold), so I got the basics from the online Puthon
tutorial (which I do recom

Kevin,
I have been taking the same plunge (and prbably for the same reason).
It's not clear whether knowing C++ well was a help or a hindrance. I
have just read the book "Learning Python" by Lutz, published by
O'Reilly, and found it pretty good. At least, I knew immediately why
your progam did
it worked, thank you :)

Hi,
Using sage-2.9.3, on Debian Etch on a core duo machine.
According to the sage tutorial p.67 section 5.3 Standalone Python/Sage
Scripts, i tried to run such a script called BMV.sage:
#!/usr/bin/env sage -python
import sys
$ ./BMV.sage
/usr/bin/env: sage -python: file or directory not found

Hi everybody,
in a nutshell I want to compute something like this MAGMA session in Sage:
%magma
P := PolynomialRing(GF(127),4);
I := ideal;
S := HilbertSeries(I);
S;
L := LaurentSeriesRing(IntegerRing());
L ! S;
The first part is quite easy as I wrapped the appropriate Singular function

Dear Carl,
I like your code; it is elegant and realy quick
but it seems that finishing your code
with Paul Zimmermann's approach
I2 = singular(I).groebner()
#print I.reduce(n12);
print singular.reduce((n12), I2)
(althout less elegant)
is a little bit faster
(0.06 -> 0.05 on my comp. :)
