Hi "drl",
you say that your text terminal's default is black background and dark
blue text, and if I understand correctly, you don't like that Sage is
using your own default color scheme. If your question is how to change
the color scheme of your text terminal then I guess it depends on your

While I'm bitching - every error generates a blizzard of pointless
information that belongs in a log file, not in front of the user's
eyeballs. That also desperately needs to be fixed.

My text terminal uses a black background. The default text is dark blue on
jet black. This is not a winning start to 8.4. How do I change the text
color. Seriously, this is the sort of little thing that is absolutely
exasperating, to get a perfect build right out of the box and then find it

They are implemented in
Hi Sagen,
Has anyone implemented a non-trivial Clifford algebra module? Such a thing
would be able to generate higher algebras recursively and exhibit 8-fold
periodicity, as well as being useful for actual calculation.
thanks (on 8.4 as of today)

You received this message because
Hello; I have installed sage 8.4 and I have problem with the derivatives
...
I have defined a function in sage of this type:
x=var('x')
def funz(x):
if x >= 0:
return x^2
else:
return x^3
but, when I try to calculate
diff(funz(x),x)
I obtain only
3x^2
and this is wrong
