I was not able to build sage-4.6.2.alpha1. Would it make sense to try
with alpha0, that I am now attempting to build?
Cheers,

Hi Jeroen / sage-devel,
Here is a demo of how I think we should go about to override malloc(), and
perhaps others, on OSX. As a quick background reminder, due to the two-level
namespace on OSX it is not as easy as LD_PRELOAD'ing a shared library on
Linux and other unices.
On OSX, we need to s

I don't happen to use Sage for this, but I know a lot of you do, and
might have technical answers. I feel the comment saying Magma is
called for the hard stuff in Sage is not accurate, but of
The current plan is to move absolutely everything into a database.

Really? I made it using Sage Version 4.6.1.rc0.

In Python 3, range() will return an iterator, which is the current
behavior of xrange(). I'm not sure about the fate of xrange() in
Python 3. See for example:

Indeed, caching does not work for Cython functions or methods. The

Hello,
Any chance that we can add simplify_full on matrices? So that each
element is simplified if possible?
/1/ I suppose you know the map function that operate over each term of a
list.
map (lambda x: 3*x, [1,2,3]) # computes [3,6,9]
# you can replace 3*x by the function simplify_what_y
Maybe combine it with a zeromq-based main loop for the worker Sage process.
Then the notebook worker and the command line Sage would use the same
codebase...
Of course this is just psychological and won't speed up any actual
computation ;-)

I'm only answering strictly to this question: yes, I think computer

This is very misleading and disturbing.
Fedora 13 Godard does NOT provide 3.4.14 and it never will.

For example,
D = matrix([[-(e^3+2)/(e^3-1) + (2*e^3+1)/(e^3-1),1],[2,0]])
In sage, this returns a complex matrix.
D[0][0].simplify_full() returns 1.
