It's possibly a stupid question, but is it possible to use the
singular_console() in a notebook?
When trying it, the answer is that singular_console() is unknown (in the
notebook).

Hi
I want to use sage-6.9 with "palp" for calculating some geometric values on
Windows8 PC.
I installed some software: sage-6.9, palp, virtualbox, cygwin, surfer.
As you know, we should open on virtualbox when we want to use sage-6.9 on
Windows.
In my case, I can use sage and palp(no options)
I try to define some noncommutative structures in Sage, but I do not
know exactly how. I found this thread:

and I check examples, but unfortunately I do not k
Hi!
At several occasions, I got the impression that excessive use of
autogenerated variables in the singular interface results in freezing
singular.
My scenario:
- During a lengthy computation, I create several 10,000s instances of
SingularElement, but most of them not permanent. So, what I am

I was asking SAGE to do a calculation that I knew was probably
laborious -- I had a plane curve (over Q) and I wanted its genus. I
defined it with C=Curve(equation_in_two_variables) and then typed
C.genus()
after a while (I was in the notebook) I just got the mysterious error

Hi,
Singular's hilb command does not work as expected:
sage: R = singular.ring(0,'(x,y,z)','dp')
sage: I = singular.ideal(['x^3-y^2*z','z^2-x*y'])
sage: I.hilb()
`sage90`
Could someone please explain this?
Thanks,
Dave

Dear all,
I'm curious about performance of Singular computations which are run
from sage:
I tried the following test:
---
cat singulartest.sage
R = singular.ring(0,'(a,b,c,w,x,y,z)','lp');
I = singular.ideal('x5-abc3', 'x7-w5a5b5', 'bc3-a7', 'b2a3c5x-yzw2',\
'xyz-wz2ab', 'bx-awz9')
S = I.std
I'm trying to compute the discriminant of a polynomial in singular
using sage; I've run in to a problem however. When I import the
following simple module and try to use discrim:
from sage.all import *
def discrim(p,x,R):
singular.set_ring(R) # or singular.setring(R)
d=singular.deg
