Hello,
I have been writing some code for sage and have encountered the following
problem. When running ./sage -br, it goes through a long cythonizing step
every time, even on files that have not been changed. I have played around
with it a little and if I run ./sage -br, wait for it to finish (

*I* don't. But it seems that the third party code I'm using does. There,
I see the lines

Aha! Since I expected it to be related with (c)python, I duckduckwent
for "python do_system", but to no avail. Than

I have both, one locally compiled version, which I upgraded from 7.x, and
one freshly installed binary. Same problem on both. Seems that
save_session() and load_session() causes all sorts of problems, especially
when using jupyter.

Does that mean you took a pre-built binary, or did you build from source?

Hi!
Trying to profile some code with %crun, I get lots of hits in the
function do_system. However, a function of that name does not appear in
the code. So, what does do_system do, where is it from, and what is
calling it?
Best regards,
Simon

I'm sorry, I forgot to mention this step:
load_session('leaf_chamber_eqs_PM.sobj')
(as opposed to a = load('leaf_chamber_eqs_PM.sobj')
My apologies!

By the way, the problem persists no matter whether the .sobj file was
created using sage 6.8 or 7.3.

But sooner or later we'll have to split combinat I think, as you

Hello all,
In the spring and summer, I worked on implementing simplicial sets in Sage.
The ticket is now ready for review, and I would welcome reviewers. Please
take a look: https://trac.sagemath.org/ticket/20745.

It also takes less time if you don't include plots: maybe 5 minutes for me
instead of 8.

Maybe the authors/users of the Chow package for sage would be interested ?
Probably not Sorger, who is busy being currently head of mathematics in
CNRS.

Dear all,
I am on debian jessy 64bit and after installing sage 7.3 I keep getting
segfault for the same worksheets that run smoothly in sage 6.8. I have now
managed to isolate a small example, which I uploaded to cloud.sagemath,
where it does not give a segfault message, but just runs forever.

Imagine it is early 2006, that there are only two users of sage, and you
