I am experimenting with a VM under W8 Hyper-V under ubuntu 12.10 server.
The aim is to have the vm automatically launch and run sage notebook so I
just connect via the browser as needed whenever in w8.

I am slightly puzzled. Trac #1173, #13050 and #13003 all aim to improve
numerical calculation of erf() and are still open. In the meantime, at
least as far as 5.2 is concerned, it appears that erf() has been updated

Yes, I have simply tweaked log_integral, to get Li and it is the linear
term that is my headache. I can't see Li in any of the integrators, but I
can get a valid integration if I return Li as li(x)-li(2) in _eval(). But
to me that seems untidy. It would be nice if _eval returned Li(x) but pas
I have had a go at implementing trac #3401, symbolic Li, and would like to
override the behaviour of integrate(), but I can't see how to do it. We
have the _derivative_ method in BuiltinFunction to define the derivative
of a function but no equivalent _integrate_ method. Is there reason why
If the intent is to control the namespace and break up into a number of small
files but retain tab auto completion and view docs then perhaps this is
strategy to consider:

And if you apply the solution in the cython module itself, the methods will
only be bound to the class if the module is imported into your session.
For example extending with file myfunctions.pyx :
from sage.graphs.graph import Graph as g
import types
def testme(g):
return g
g.testme=ty
Successful build with the sage atlas.spkg using 'fast' default arch,
but if I build with environment set to use my own atlas ( also 3.8.4)
matplotlib won't build; it thinks numpy is not installed. Not sure if
this is specific to 4.8 as I have only just got my atlas up and
running.

Graphviz would not install as pkg-config was not reading the
pangocairo.pc in the grphviz configure file in the sage environment so
it was not setting the includes correctly. Cause is a duplication of
SAGE_ROOT definition in sage's local libpng12.pc. This problem with
the libpng.pc file also fea
I have managed to get graphviz to build on ubuntu. It appears that
the sage environment confuses configure and it can't find a number of
header files. Adding the following options to configure in the spkg-
install file resolves the problem for me:

I am trying to build Sage from source in Puppy 4.3.1 Linux but atlas
will not build. I have successfully built 4.3.4 and 4.2.1 in the
past. The only significant change is the hardware. I now have a
Intel 750i on a Asus p7p55d motherboard and 4Gig DDR3 ram instead of a
Intel Dual Core.
Now well
