Buon giorno everybody,
I am able to speak and write Italian (although my writing is rather
poor). The only thing is that I'm not familiar with the "Italian" used
in mathematics.
Best wishes,

Wow very cool! I've been wanting to try it out for some time now, but I was
just too lazy to install it manually...
Thanks William&Alex!

Is there any way to find solutions to arbitrary systems of linear equations
in Sage? I mean, without using an external package? (is there even an
external package with that ability?)
I'm not interested in fast computations, just the ability to solve systems
would be useful (or wouldn't it be? It se

Well, I think it needs a rewrite, not just some editing... but on the other
hand, it's not that bad either.
Still, it has to be renewed.

Hello everyone,
I've just been playing around with SymPy a bit more lately, and I found that
the 3D-Plot implementation is really nice!!!
Why isn't that the default plot3D-way for Sage command-line use?

know it's already th

Quite fancy, but the thing took about 1 Minute to load on my Kubuntu
machine, and Firefox was frozen in the meantime!!!
Yes, that's right, it's Java ;)
But it sure could be one possible way to go. (I must say I like the AJAX
stuff more, although I really have NO CLUE at all about web programming...
sage: u=vector([2+3*I,5+2*I,-3+I])
sage: v=vector([1+2*I,-4+5*I,0+5*I])
sage: p1=u*v;p1.expand()
9*I - 39
sage: p2=u.inner_product(v);p2.expand()
9*I - 39
sage: p3=u.dot_product(v);p3.expand()
9*I - 39

3 - 19*I

I'm not sure whom you are aiming at with this description, but I think there
should be some emphasis on the natural sciences too.
I think the description should be something like "CAS *AND* system for
computational sciences", but I'm not sure about how to make it sound good.

Just to give my point of view: (I'm not taking part in development at
the moment either)
A native windows port seems like a good idea, iff there are people
willing to do it and iff it won't take any ressources from other parts
of the project. I'm sure a port would also increase the overall
quality
Hmm... the author of this post doesn't seem to realize what Sage is

Yes, it really looks the way it should, in my opinion.

I really like what Martin Albrecht posted, I think it's very simple and yet
representative. Maybe there could be one or two more symbols in the banner,
in my opinion the SymPy-snake would fit somewhere or e.g. the SciPy Logo (I

Well, after reading the comment THOROUGHLY (I'm not sure why I've done
that), I agree. I must say that I wasn't aware of the fact that THIS is the
general level of intelligence of slashdot comments, although I occasionally
skim through the news.
Anyway, it surely IS publicity :)
Best wishes, Fabio

Is it possible to implement a progress meter for -upgrade? I've never seen
something like that with a compiling process, but why is that so?

So basically, on the long run, you would like to use SymPy together with
everything rewritten in Cython? Did I get it* correctly?*

He'd find it interesting to integrate mathGUIde into SAGE. About the
licensing: mathGUIde is GPL (oh yes), he just emphasizes that the Qt
noncommercial license for Windows is a bit restrictive,
I hope my short description of the GPL isnt't too bad... the rest should be
quite alright.

The original Webpage says "[mathGUIde] ist Freeware und wird mit allen
Quellen verbreitet" which means that "it's freeware and is distributed with
all the sources".
So it doesn't state any licensing details e.g. whether you may modify the
source etc.
Maybe I should download it and look into the sou
That sounds very good.
But what would be the advantage of using RPy instead of your pexpect module?

I mostly agree with the things stated above, and sage.calculus is clearly an
important part for applications.
Still, we should also consider other possible uses. I recently talked to
Michael Abshoff about whether we are planning to make R a part of SAGE. He
told me that William was convinced that i
I'm just copy and pasting something which I spoke about with cwitty and

So this is it:
Why is there not emphasize on sagemath.org about the fact that sage can also
be used for natural sciences/engineering applications etc.?
I think that first of all this would mean more users comi

If anyone has the time to do so, please read my original message and answer
