Hi
The links from "open source" on www.sagemath.org,
both in the top right and in the first sentence,
link directly to the repo. Would one not expect
an intermediate page with an explanation of what
open source is, and why? Or at least a sentence
at the top of the repo directory listing which on

Hello.
OK, you're probably right, it's a hardware problem. It's the
most credible explanation, even if the exact circumstances
triggering it will remain obscure. I will follow your suggestions
and try a step by step compilation, following the script.

To elaborate on the remarks by William: compiling ATLAS is some of the
most demanding things you can do to a CPU since most of it has next to
no IO and it attem
At the moment, if I create an integer matrix, there are methods
"elementary_divisors" and "smith_form". Example:
sage: m = matrix(ZZ,3,3,xrange(9)); m.elementary_divisors()
[1, 3, 0]
sage: m.smith_form()
([0 0 0]
[0 3 0]
[0 0 1],
[-1 2 -1]
[ 0 -1 1]
[ 0 1 0],
[ 1 4 -1]
[-2 -3 1]

Are there two different ordering issues here: (1) do zeroes go at the
beginning or at the end? (2) Does each nonzero entry divide the next,
or the previous?
For (2) I think the usual is to have each divide the next (so for
example any 1's are at the front), though pari does the opposite; for

The ordering is meant to correspond to inclusion of ideals, so if 1's

In conversation with Mike Hansen in IRC the following come up:
* The Sage<->Maxima interface does garbage collection already on the
Maxima side
* it might be also a problem with matplotlib, but the CPU time
indicates also Maxima (the Pylab example might expose the same problem
in matplotlib)

OK. Btw, what mechanism did you use to build Maxima?
ASDF or defsystem or ??

Hello folks,
Sage just got mentioned at http://www.linux.org.ru/ and we are getting

Sure, we need to make that the fixes we had applied (the Itanium ones
IIRC) made it into upstream and then we should be good to go. Judging
from the changelog not too much has changed,

Here's another option ... Robert's main issue seems to be that the
question of how to deal with the fact that the merge comes in halfway
through. So rather than have different commands,

I don't want to start a religious war but this is trivial in
a git repository. There was some talk a while back about changing

Hi all,
I was kind of burned out after my math final today, so I decided to
have some fun and create a new theme for the Sage notebook in line
with my current Firefox theme, PitchDark. Basically, I just identified

I think it would be cool if Sage could do this:
http://rogeralsing.com/2008/12/07/genetic-programming-evolution-of-mona-lisa/
Several of the comments on the site are requesting the source code (I
particularly liked: "source code or it didn't happen").
