Dear Sage developers,
In another thread, I already announced that I'd like to have
"Symmetric Ideals" implemented in Sage (for starters, it is about
polynomial rings with countably many variables, and a toy
implementation of a Buchberger-style algorithm for computing Gröbner
bases for ideals that

Dear Sage developers,
Let me recycle this thread to report progress on the bookshelf of
standard object behavior. I just posted a small patch:

Yep, -1 on their unfortunate decision. I hope the properly document
their bug fixes in the release notes so that we can backport them.

I'm not sure why you are getting different results from sagenb.com and
from the "shell", but I would guess that you must be using two different
versions of Sage. Either way...
The problem is that when you divide two integers, the result is always a
rational number, whether or not that rational nu

um, implement it and submit a patch?
I noticed a slight blemish on the index page that appears on the
mirrors:
The problem is the height of the frame. It's given in px rather than
em. So, if someone selects a font that is higher than 16px, the text
does not fit in the frame. Firefox 2.0.0.14 (and a lot of others as

Hi Sage-Devel,
Can we just frickin' get rid of this stupid "error code -7" crap once

I don't want to release another Sage with this crap. Can't we just comment
out some javascript lines somewhere? Comments?
(Yeah, yeah, I should just do it myself... instead of whining.)

Dear Florent,
I hope you don't feel offended by my questions. I knew the mathematics
you were writing about. I was just saying that either the function
basis() should be renamed to canonical_basis() or all what you wrote in
your mail should better go into the specification of basis().

Thanks for the reply ahmet. Turns out we need 64 bit windows, which I
should have mentioned.
However I have just been told we in fact have Windows figures for Core
2. So somehow I have got this mixed up. It was linux on Core 2 we
needed. But of course that is trivial.
Thanks for your help, but w

Does anyone have access to a Core 2 machine (any speed) with Windows
on it. Brian Gladman of the MPIR project has ported some new assembly
code of Jason Moxham's to Core 2 and wants to measure the performance
and test the build of the new code on a machine with Windows and Core
2 architecture.

As usual in mathematics, we identify two different things, whereas when
writing code we have to be very precise. The universal property in the

Perhaps the use of a "patch" needs an explanation.
