Hi
I'm running Ubuntu 14.04 and the PPA which is the downloaded binary.
I wanted to enable notebook(secure=True), which prompted me to install
pyopenssl.
sage -i pyopenssl successfully installed but prompted me to make.
make finished without error.
sage now does not start:

No obvious things in this log. But a careful reading shows that both
glpk.h and glpk/glpk.h where found. glpk in sage only ships glpk.h
so the other one must come from the system.
The output of rpm -ql glpk-dev or would it be glpk-devel would
show us what has been detected from the system.
But
[paul.mercat@octopus ~]$ rpm -ql glpk-dev
package glpk-dev is not installed

If you used the PPA shouldn't sage -i have failed with a permission
error, how come you can write into the Sage install? In any case, IMHO you
are best off compiling all of Sage if you want to install (compile)
optional packages as well.

Hi
I can change the permissions on the PPA folder, these are imaged desktops
for labs, and I can always test and reimage on any computer.
I have in the past often installed optional packages with the PPA.
I will try from source, and see if it persists.
Regards,
Jan

The ticket only adds a new feature allowing for the natural 0-based
permutations. Otherwise it does not change the current behavior.
But why shouldn't the current behaviour be deprecated? I think requiring
that the domain is 0..n-1 (is possible, with a check) would be much better.

The git trac log ticket only inspects the log of the current branch
(just like git log, except that it understands trac ticket numbers). So
you need to be on a sufficiently recent branch if you want the log of these
tickets.

Hello sage-devel,
could somebody please review the small patch
http://trac.sagemath.org/ticket/16827
It fixes the sage-preparse script, which is called when running a
foo.sage file through the command line, to use atomic_write. This avoids
race conditions when multiple Sage sessions are run
For the record, I'd rather have both 0 and 1-based permutations act on
matrices in the the natural way (as permutations on an ordered set,
regardless of how that set is written). So there is no need to get rid of
1-based permutations. However, we need to be able to tell 0- and 1-based
I was dabbling in arithmetic when I noticed that the following leaks memory
at about a megabyte per second:
F.a = GF(11^2, 'a')
R.x, y = F[]
while True:
_ = x(a, a)
Now I would have thought that evaluating polynomials is a fairly common
operation, so I'm sure somebody
