Hi,
I am surprised by the output (9.8 and 10.1 Ubuntu):
var('A,B,C') factor((A-B)*(B-C)).list()
var('A,B,C') factor((A-B)*(B-C)).list()
var('A,B,C')
factor((A-B)*(B-C)).list()
[-B^2 + B*C, B - C]
I expected [B - A, B - C]. Any explanation?
Kind regards,
Roland

Hi,
Memory leaks are annoying. For instance #9298. Could somebody have a
look at it?
Thanks in advance!

Hi,
Maybe the following is of some interest. Last week, I was in both
Beijing and Shanghai. The main webpages www.sagemath.org as well as
http://groups.google.com/group/sage-support could be used, but no
other Sage webpages! It seems that a potential huge community can't
use Sage.

On this topic, Sebastian Pancratz and I wrote an optimized
implementation of trial division to find the smallest factor of an

Hi,
I use ZZ(ss).factor(proof=False,limit=10^5).
By changing 'limit' you limit the search.

Hi Alex,
+10 for the person who is willing and able to make a recent VMWare
Sage image (x86_64). Since April I rather use VMWare Sage than the
Virtualbox version, despite the disadvantages of the old release.
VWMare did change a lot; a good reason to support both Virtualbox and
VMWare in the
Hi,
Look at:
R.A,B,C=QQ[]
print get_memory_usage()
for i in xrange(1): (an,bn,cn)=map(lambda x: abs(x((1,8,9))),
(A,B,C))
print get_memory_usage()
819.94921875
828.94921875
Why is the memory usage increasing with 9Mb? This only happens when
map is used repeatedly!
I would expect no
Hi,
I found a more simplified example:
print get_memory_usage()
for i in xrange(1): A(1,8,9)
print get_memory_usage()
Why is type(A)

Hi,
May I extend the question somewhat.
If you look at
http://www.sagemath.org/doc/tutorial/programming.html#section-standalone
, you find the text:
It is also easy to access C functions defined in separate *.c files.
Here’s an example. Create files test.c and test.spyx in the same
directory
?

I have a small (nonsense) example of a program I would like to be able
to convert to cython. But I don't know how to convert:

Hi,
Using cython, I want to make optimal use of static data. The reason is
that lookup is (often) much faster than recalulating. I now use:
cdef list nice_list_name=[3 , 3 , 3 , 3 , 3 , 3 , 4 , 4 , 4 , 4 , 4 ,
4 , 4 , 4 , 4 , 5 , 5 , 5 , et cetera]
But this didn't increase the speed.

Just for others (and maybe for the manual):

input_file = gzip.open(F, 'rb')
