IMHO, Sage does not use apache at all. It runs its own webserver, on port
8000.

Can you give an example of what you mean?

I had a sage server running on an imac running os 10.6.
I stopped the server and tried to get it running again, and
now I'm having problems.
1. I tried logging in on the imac as a user, then starting sage.
I got the message appended below in the terminal window that pops up.

Well, The binary that worked on both my netbook and desktop is the one
that has the name "*
sage-5.0.1-linux-64bit-ubuntu_10.04.3_lts-x86_64-Linux.tar.gz"*. It's all
the information i have about it. i downloaded the package may be two weeks
ago.
I just download it, untar at, say /home/sagemath,
Compile sage from source in mi netbook would take soo many time. the last
time i did it took about 6 hours, but unpacking a precomplied binary... its
a matter of some minutes.

After some digging -- and a fortuitous control-C at the right moment
-- it looks like it's trying to construct the basis for the ambient
free module. This will be a list of 10^4 vectors, each 10^4 elements
long, so it's not surprising it takes a lot of memory.. adding a print
statement in the loop
I also use Xcode 3.2.6 (freshly installed) , but building always crashed
when gcc 4.6.3 was going to be installed on my machine.
I figured that I could install the gcc package manually, downloaded it and
ran the installation...with the same result.
really don't know what the problem is...

I'm using sage 4.6.1 (release data 2011-01-11) on Linux.
When I tried to divide a vector of ~1 elements by a scalar, it ran out
of system memory and crashed.
code:
n = 1
v = vector([0]*n) # ok so far
v2 = v/1 # kaboom
I repeated this process for increasing values of n st

Sometimes a workaround is possible:
sage: x = var('x')
sage: y = function('y', x)
sage: C = var('C')
sage: f = desolve(diff(y,x) + y, y, ics=[0,C]); f
C*e^(-x)
sage: c = var('c')
sage: f = desolve(diff(y,x) +c*y, y,ivar=x, ics=[0,C]); f
C*e^(-c*x)

Dear Robin
Actually you are working with machine precision, i.e., eps(10^-16) in
double precison.
it means that 1+eps == 1 in double precision.
try
from mpmath import *
10^-16*mp.rand()
or, as you have coded
from mpmath import *
mp.dps = 30
(mpf(1.0)+10^-16*mp.rand())-mpf(1.0)

I am trying to generate random numbers and am running into roundoff
problems:
RealDistribution('uniform', [1,1+1/10^16]).get_random_element()-1
This returns zero every time for me, something that is almost surely
wrong. I would expect a number chosen from the interval (0,1e-16).
