That sounds good to me too.

Hi,
I moved everything off of the "sagemath" virtual machine, except for
planet.sagemath.org, which I hadn't got around to. This afternoon the
sagemath virtual machine mysteriously stopped working, and I can't get
it to work. So planet.sagemath.org is going to be down for a while
until this gets

I just did the following:

(2) "cp -rv SAGE_ROOT/d

There's also http://trac.sagemath.org/sage_trac/ticket/1173 with a
different approach.
I'm fine with letting #1173 fade in fav

apply cleanly to sage-4.8.alpha2 or later:

I was going to write a doctest for #6777[1], but the traceback throws a
few errors before the exception:
sage: RealField(300)['x']([ ComplexField(300).gen() ])
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid

I also work in math far from the Cartan-Kähler theorem, but I'm
enthusiastic about having more support for differential forms in Sage.

And document very clearly how one *would* test them if we ever had
What's the latest line count for Sage, meaning all python & cython
files (but none of the spgs)? I'm guessing someone has a script to do
this count.
I am preparing a 30-minute talk on "Sage as a research tool" for Sage
Days 35 (which starts on Saturday here in Warwick).

that's a good idea! next to the histogram i did above, i also want to

Just to amplify what Bill said below, most CPUs these days have
some sort of power-saving mode that will be in use by default. This
means that if the CPU is not fully loaded when you start your test,
it will take some time (typically not more than a few seconds) for it
to ramp up to full speed (ir

The problem is always the same : some Sage graphs are created as instances
of BipartiteGraph (*), and even though some methods may not need to modify
it they copy it and work on the copy, or well
The point is : it must be the 5th bug report I see whose answer is "You
