You probably already know this, but if not: perhaps you accidently
clicked to the left of the matrix, and put it into latex mode. Once
in this mode, I think it will stay there for that cell. So just click
to the left until you get want you want.
If you already knew to try that, I don't know wha

Dear Sage-devel,
The JMM are in Washington, DC, this year, and I wanted to point out a
few opportunities/events of interest to Sage folks.
First, David Joyner, Marshall Hampton, and I have organized a panel
session on using open source technology in undergraduate courses. We
will definitely hav
I also had a similar problem that something was not typesetting, but
didn't know about the left click, so maybe that was the cause.
Another (and much more annoying) issue I had was missing plusses...
When I was opening an existing worksheet, then SOMETIMES plusses were
missing in SOME cells (hard

Hi:
There will be 2 SAGE-related sessions at the next AMS national meeting.
One is an AMS session on SAGE and mathematical research
http://www.ams.org/amsmtgs/2110_special.html (not yet
scheduled for a specific time) and the other an MAA panel discussion on

I'm planning on going, though it's obviously still far off. Is the
plan for it to be a fractionally numbered Sage Days again? 10.5 or
11.25 or so
Good idea! I added that to the wiki: http://wiki.sagemath.org/SAGE

I've been looking at some of the trac tickets. Two of them caught my
eye, and I'm curious about them:
http://trac.sagemath.org/sage_trac/ticket/2515
http://trac.sagemath.org/sage_trac/ticket/1915
Both of them deal with Infinity. In the first one, someone suggests
doing away with ExtendedRation
Are any other Sagers going to be at ANTS next week?

So, I think I was the one to rework infinity most recently. I don't
really have time today to expand at length on the issues you brought
up, but I agree with them to some extent. I will note that a coercion
is "a natural map into the object," which is why your first example
failed, but the __cal

The current implementation using InfinityRing and SignedInfinityRing
is very close to having a value saying "not defined" (i.e. NaN), and
viewed in that light the way things currently work makes sense. It
works for the purpose of not raising an exception on division by zero.
I am not at all sure I

Hi,
A while ago we had a huge thread on sage-devel with lots of criticism
that I dutifly
listened to which resulted in the current sagemath.org frontpage. Every
sentence of the current sagemath.org page got carefully written and rewritten
numerous times based on *your* feedback.

+1 on too much blueness.
A couple of comments that were made previously but I think are
important to reiterate:
1) Don't place equal weight on all the links. I think that the
Download link should stand out since that's what most people want to
do, or at least that's what we want them to do to tr

2) Going to the download page, the first sentence I read is "Sage for
Microsoft Windows is currently not native available," (and at the
first read I actually missed the word native). I don't think it is
good to start describing techni
