Hi,
The entire sage.math cluster (and all related resources) will be down
from the wee hours of the morning on Friday, September 9, until
probably around 2pm that day. All times are PST. This is because
there was a serious electrical problem in the server room, and the
electricians have to come
The above of course modulo the inconsistency's python allows. Since defining
both:
class C(A,B):
class D(B,A):
don't give errors yet, but it does make it impossible to inherit from C and
D wich might be annoying.

I was also thinking about checking if the whole subcategory category graph
is also a valid python inheritance graph. This so that inconsistencies
cannot exist silently. But I guess that is also automatically checked by
python as soon as you construct an explicit parent in each category so this

Hi Jason,
Does that use fast_callable? I couldn't find a mention of fast_callable
in the worksheet anywhere except in the descriptive text at the top.
For some the mentioned worksheets are not at there.
I republished them:

Journal (an MAA publication), there is a book review of Stan Wagon's
"Mathematica in Action", 3rd ed., which devotes a fairly lengthy
afterword to the issue of price of the M's and introduces Sage.

on macosx 10.6 x_64 with Sage 4.7.1 built from source I get [0]
And the same on Linux x64 with Sage 4.7.

On my 4.7.1 I get [1] as expected. That's on my own build on ubuntu.

Hej Guilherme,

Hello,
I'm using Sage 4.6.2 on my local machine and when I use the command
DirichletGroup(1)[0].values()
it gives me the correct values (namely [1]). However, in Sage 4.7.1, it
seems to return [0], which is
false since everything is coprime to 1.
Thank you,

In the first place, the mathematical inheritances must be obeyed.
However, mathematically, it makes no difference whet

Hi Maarten,
I appreciate your example. I am doing modifications to accommodate the
fast_callable. The only thing is that I have to provide all the
symbolic variables, and I have several of them
The jacobian is a square matrix and I will try it via a list of lists
of fast_callable functions.
