Same here. That is because 5gb / 8 < 1gb. But I'm pretty sure if you had
only one process
I forgot to mention the C++ packages, the complete list of external code
in Sage (AFAIK):

I've just tested it with Sage 6.7.beta2 (since it incorporates #17821): it
works, both in Sage notebook and IPython notebook.
Thank you!

partitions_c could probably be replaced by the implementation in arb if
people want to drop it. But having two implementations can be a good
thing too...

Why arb (which deals with floating point)?
We already have 4 implementations in Sage to compute the number of
partitions.

Because arb has the best (fastest and most rigorous among the "fast"
ones) implementation as far as I know. As for why Fredrik put it in arb,

Right-clicking shows no special menu. Looking at the html source, I see:
Let \(R\) be a commutative ring. The

the algebra generated by \(x_1, x_2, \ldots x_n,

Is that an upgrade from earlier sage versions? Upgrade to ensure that the

Currently, evaluating a polynomial ring element on a symbolic expression
returns a result in Horner form:
sage: pol = QQ['x'](range(10))
sage: pol(x)

no. all completely fresh. However, there is a sage (my production sage
:-) in the path, might that be a problem?
Thanks,

Shouldn't be a problem, though maybe you can try without and report back...

Hello,
This patchbot is running version 2.2, which has several disadvantages, in
particular it uses the master branch as a base. This means that it only
works nicely when "develop" is not a beta but a release... Not so often, so
to say.
So, please, upgrade to patchbot 2.3.3, available here:

I wouldn't want another environment variable for that. If we have to,
chunking at 10 would be fine. Though ideally this would be dealt with on
the cython side, I made a post here:

Well, easier for playing than editing the sources... ;-)
A good default value should be chosen automatically.

I think it's ok for machines with 2
Indeed, no change.
I installed konqueror, where things work. So it is a firefox problem...
