Hello,
I'm not sure if I should open a ticket on the following issue, or if
this is just a case of "Error Between Keyboard And Chair". Here is a
simplified version of what happened.
I had parents A and B and map phi between them, as follows:
sage: A = CombinatorialFreeModule(ZZ,[1,2,3],prefix='X

Agreed. But just to be precise about the definition of 'unknown', I
think it should be ok if

Thanks Simon and Florent,
This is now http://trac.sagemath.org/sage_trac/ticket/9138 .

The same thing happens with `summation` and
`summation_from_element_class_add`, and various other methods (for
instance `R.addition_table`). It also happens for both single variable
and multi-variable polynomial rings. Is this behavior known, or should
I open a ticket?
Thanks,

Very nice!

ASCII-only source code.) :-)

Thanks for your feedback, everyone! term = coefficient * monomial it is.

Hello all,
I'm currently working on enriching the ModulesWithBasis Category in
Sage, and I have a question about what to call things. Namely, when
given a sum of generators with coefficients, what is a 'term' and what
is a 'monomial'. (Typically, I am asking for leading/trailing
terms/monomials)

Hello sage-devel,
I found the following behavior surprising... is it intentional?
sage: R. = QQ[]
sage: R.foo = 1
sage: reset()
sage: S. = QQ[]
sage: S.foo
1
I understand that there is a unique polynomial ring in one variable over
QQ, but I was surprised to see it persist through a reset().

I agree. I am well aware that 'rank' and 'unrank' are very common in
some places, but I found them non-intuitive at first. I would prefer
something like index/[] which I find more natural. (Th

This seems like a bug to me:
sage: dd = {(0,0):1}
sage: %timeit matrix(8,dd).det()
10 loops, best of 3: 213 ms per loop
sage: %timeit matrix(8,dd,sparse = False).det()
100 loops, best of 3: 629 µs per loop
Should I open a ticket?

That way people who prefer one idiom over the other will see the one
they like, and hopefully nobody is confused into thinking they are
different.

Hello all,
I reporting the following bug here because a) Trac is currently down and
b) it's bad enough that I'd like to call attention to it.
The following test was done in 3.3.rc0.

Hello,
I wanted to call attention to Trac #4303, which I just opened, in the
hopes that the right person to fix it will see it. It has to do with
the color of plotted points.
