I've just got round to using the notebook under 2.10.alpha4 and find
that
my problem about cells occasionally not evaluating is still happening
there. I checked the Firefox error console and note that there is
an error message there which says:

Further info: I've retried it a large number of times and it only
happens occasionally.
It's not related to any particular cell or content as I have seen it
on several
different cells during this testing.

but can't

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?
Do they;

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
Either this is a bug or I have been teaching students the wrong thing for years:

[7,8]
There are two sets of invariants for a finite abelian group. The
"elementary divisors" should be a list of

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
at http://www.mypclinuxos.com
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 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.
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.

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

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

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

b) Development

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
