Thanks for the suggestions.
I have avoided a full developer installation of Fedora 12 (a reason to
install the binary version of Sage) so that is likely to be the
reason.
Here's my installed libraries etc:
$ ls -l /usr/lib64/libstdc++*
lrwxrwxrwx. 1 root root 19 2010-04-03 09:41 /usr/lib64/lib

As William pointed out, you can make a list all at once using
lst = [None]*100
But 100 is not a large number, so you should just wr

I can't figure out why the following commands ends with a TypeError

Very nice Thierry! Thanks for you reply. I'd give that a try for the
faculty in a later phase..
I am installing Sage for 10 graduate students to try.. The university
system is running MySQL and I would like to query against the legacy
DB for these students.
Got a patch for that?
Do you know what
Hi,
I found a more simplified example:
print get_memory_usage()
for i in xrange(1): A(1,8,9)
print get_memory_usage()
Why is type(A)

Hey guys,
First post .. I've personally been using Sage for over a year. I have
convinced the Math department to give it a shot.. And I am to deploy
it on a testing server (Ubuntu 9.04). So some of the graduate students
will work on it to see the learning curve..
