Hello folks,
right on the heels of the 2.10 release here is 2.10.1.alpha0. Since
we closed 28 tickets during Bug Day 9 with the help of many - more
about that once I have caught some sleep - it seems a good idea to
get this tested. Since we updated the GNUTLS and packages it depends

lwn, the Linux Weekly News, often has interesting articles about
software development. This week there were two that should be worth
reading and maybe can learn something from them:
a) Development issues part 1: Project communication - see

Hello folks,
Sage 2.10.1.alpha0 is on the way and merging has gone well. But
there is a boat-load of patches (about 55) that need reviews to
get merged. So if you have a little time come on over to trac
or #sage-devel and help out :)
Cheers,
Michael

I don't know for sure how other systems actually implement implicit
plotting.
I would think you might try to use that the gradient of F
is orthogonal to the level set curves. In particular
if (x_0,y_0) is a solution to F(x,y)=0, you know that to follow
the level set curve you should move in a dir

No need to argue -- if the literature uses the terms in different
ways, we implement one and make sure the documentation alerts users to
the possible confusion.

As it is stated in the documentation for abelain_group.py, the terminology for
elementary_divisors follows Rotman's An introduction to the theory of groups.
In my 4th edition, it is defined on page 132. In the US, Rotman is a
common reference
and that was the reason for that choice of terminology.
Hi,
Here is a suggestion from a Sage user (my younger brother, who donated
a lot of support
and labor for our AMS booth by the way) for a video that a Sage
developer could make
which would be very helpful to new users.

As I've posted here before, I have been working on packaging up SAGE
into an RPM form. Well, I am happy to say that I finally have
something that (seems to) works. If anyone here has the ability and
the spare time to test out the fruits of my labor, please take a look

Either this is a bug or I have been teaching students the wrong thing for years:
(in 2.9.3)
sage: A=AbelianGroup([7,8])
sage: A.invariants()
[7,8]
sage: A.elementary_divisors()
[7,8]
There are two sets of invariants for a finite abelian group. The
"elementary divisors" should be a list of

First, this is just a special case of contour plots. There you seek
for an area where F is inside an interval, e.g. 0 to 1 or 50 to 150 -
and colorcode them. Here you

This is kind of getting old. How do programs implement implicit
plotting, say of F(x,y) = 0? Is it something we could just
implement in two hours?

It's not related to any particular cell or content as I have seen it
