Hi,
I created a Cython Debian package, which you can download from my repository:
http://debian.certik.cz/
It works, information how to easily use it on Debian is in
README.Debian, but it still needs some work until it could be uploaded
to unstable (man page, copyright etc.), but those are most

Hi,
I would like to discuss how to improve calculus in SAGE.
I know, that currently, most of the developers need other things more

in SAGE. For example all my friends and colleagues cannot really use
SAGE at the moment, because

Not necessarily. In the long run I want to have a very simple but fast

I downloaded the binary version: sage-2.8.13-i686-Linux-debian32.tar.gz
I tried that on my laptop and it indeed took only 57s, which is less
than a minute. So there are probably some problems on my end.

Hi,
how is the SAGE API reference done? Using docutils?
I am looking for some tool for documenting SymPy and so far I tried:
epydoc, pygment, pudge, apydia and all fail for sympy producing some

So I am curious what your experience with such tools are and what is
your favourite?

I think google makes it user specific, since I just tried that on
another computer and there sagemath is the first result for "sage"!

Well, yes, but all people I know of that use Mathematica use Windows

as a Christmas present from me, Cython made it to Debian couple of hours ago:

Could you please Robert release a new version with the automatic

I could of course take the hg changeset and patch the debian package,

I needed to write 2D Ising model simulation into my school and I
decided to compare the two possible solutions how to do it, so I of
