That is correct. I still consider this odd, but you can always

On the download page for the source code [1] it would be useful if, next
to each link, there was a link to an md5sum (or sha1sum, etc) of the
tarball. I know we've seen some corrupted downloads, and if an md5sum
link is easy to find, it might encourage people to use it.

I'm not sure I agree that this is a bug. After using the name var
in the loop, the value of var is y. y is a symbolic variable, and
when evaluated at the string x,y it returns x,y; this seems like
desirable behavior (to have string-valued functions seems OK to me).
Or another way to put it: if

Ah, ok. I am probably not the right person to weigh in on what
symbolics should do. I'll be happy if I can do most of what I could
do in mathematica - since I used it for 16 years, it defines what I
expect, but of course it won't always be the right design to follow
for Sage.

Hi Rose,
Second, it becomes pretty long went there are complex numbers in my
Tuples (more than 30 secondes for 7 elements).
This does take time, interestingly when the numbers are symbolic:

sage: %time

It occurred to me that maybe I should supply a more non-trivial

replace exponents of polynomials with the famous 3x+1 sequence
(Collatz, whatever) until they stabilize:

Didier, I am sure you are right but I thought it best to deal with one
matter at a time! From Rose's posting it looked as if she was just
trying to count instances in a list, while Tuples is a much more
complicated function.

It turns out that next year it is very possible that all USNA freshamn will have
an asus eee. The debate seems to be about the amount of ram it should have.
I can borrow one next week. It has xandros linux 500M ram, 2G hard
drive, wireless but
no cd or dvd drive. I think I can also borrow a 8G SD

I've built a new version of the sage-vmware-deluxe-3.0.1 virtual machine.
http://www.sagemath.org/SAGEbin/microsoft_windows/sage_deluxe.html
It is running SAGE 3.0.1 on (X)Ubuntu 8.04 LTS patched as of 5/9/08
Enjoy!

Hi all,
sage: a=matrix(QQ,3,3,range(9))
sage: v=matrix(QQ,3,1,range(3))
sage: (latex(a\v), a)

I think it has to do with the parsing of latex(a\v); it seems to try
doing (latex(a._backslash_(v), a) (note the missing parenthesis in the

How about
How about something like the following:
cpoints = [0, 1, 1+I]
points = [[real(z), imag(z)] for z in cpoints]
polygon(points).show(figsize=[8,8])

Thank you, this is what I was trying to do!
