[sage-devel] Re: multi_polynomial_element add/sub slower than mul?!?
I am a member of the Singular group and working on standard bases over rings. Therefore as a test case we have implemented standard bases for Z/2^n[x_1,...x_k] and the corresponding polynomial arithmetic. As we plan to allow this computations for Z/n[x_1,...,x_k], we will implement corresponding polynomial arithmetic. If this is of interest for you, I can bring forward this implementation in the schedule. It is not really difficult, as Z/2^n is present. The minor points are handling division, gcd and lcm. At the moment, we allow division by zero divisors, if possible, even if it may not be unique. ...

I had some explicit interest from our statistics folks on getting R

os X) and had the same problems I had on an os X ppc - some sort of
linking problem. I will continue to try.
Thanks! Report anything here.
I was also asked if SAGE had linear programming functions. I know
that there is one included with cddlib, which is added as part of
polymake - is there another that is easier to use?
No, there's nothing that is easy to use yet, that I'm aware of.
It would be if either somebody made a SageX interface to
cddlib, or investigated other options (e.g., does GSL do
anything?).

[sage-devel] Re: multi_polynomial_element add/sub slower than mul?!?
Okay, I looked into the issue. In the top version from Singular of the repository now has a not yet fully tested polynomial arithmetic for Z/ n with the following functions: 1) +, -, * of polynomials and numbers 2) where possible / and inverses of numbers (polynomials by monomials just a matter of a few adaptions) (div by zero divisors is allowed, as long as possible) 3) gcd, lcm of numbers (in Z/n) Uses the same API as arithmetic for polynomials over fields. If somebody has access to the repository version, you need to compile Singular with #define HAVE_RING2TOM #define HAVE_RINGMODN in mod2.h. You can use the new coefficients with: ring r = (modnat, 200), x, dp; == Z/200[x] or ring r = (modpow, 2, 13), x, dp; == Z/2^13[x] ...

The day after the sage link did show up on that slashdot story I had ~40 downloads of binary sage which was roughly double the number of binary downloads for the whole last month from the cocoa.mathematik mirror. Of those 36 were for cygwin, which I would not expect from the slashdot crowd. Maybe somebody should submit the release announcement for sage 2.5 to digg and slashdot once the release has been made.

[sage-devel] 'sage -t' stops
Hi, I haven't seen a comment about this on the list, but maybe I missed it. When I run sage -t, it comes to a halt early on, after spinning off 'wish' and displaying a graph. It seems that this window needs to be explicitly dismissed (closed) before sage continues. It does this 3-4 times before continuing without hand-holding. Is this expected? I'm running 2.5-alpha2.
