If you do
sage: RealNumber=float
sage: Integer=int
before defining the functions, the ode solver runs dramatically
faster.
This is because the function calls get much cheaper as nothing is
accidentally

Hi all,
I am a brand-newbie. I tried to install the GAP packages and got an
error.
Sage told me to email this group, so here I am...
I am running Xubuntu ("Feisty") on an HP-Compaq nc4010, in case that
matters.
The tail end of the error follows. Thanks in advance for any help.

Recently I set up the VMware image to be a class server and from that I
experience, I think that it is still a bit beyond the reach of a
non-unix person to easily set up a good secure sage server. While the
vmware image is an absolutely fantastic base requiring minimal extra
configuration, th

I agree, I think, that doing the configuration via ncurses would be a
step backwards. People who are not familiar with *nix are most likely
not going to be familiar with managing their computer through text
(curses or not) interfaces.

Thanks.
I tested this by buying a copy online on the 25th. It was printed 3
days later and just
arrived, carefully packaged, today. Printing quality and binding look good.
No complaints.

Thanks, now I have already wasted about 1/2 hour on these, and the
total will surely increase. It reminds me of a recent comic:

When you're done:

Presently, because forall and exists return tuples rather than
booleans, their return value is always True, so they cannot be used as
a predicate, which is very unintuitive given their names. Proposed
solution: optional parameter witness (default: False) that determines
return value type.

Hmm... witness is very unintuitive; maybe we can think up a better
name. Also, there are functions in Python which have similar
functionality.
sage: l = [1,2,3]
sage: any([i == 2 for i in l])
True
sage: all([i == 2 for i in l])
False

That's instructive. In that case, forall and ex

I agree with Nils. I just started using forall and exists and found
it stupid to have to append [0] to get the boolean value. And given
their existence I never looked further to find the python any() and
all() functions.
