Hi,
I hired a student (Elliott Brossard) this summer to write a nice
web-based Calculus tutorial using sage.
Obviously I intend to carefully read through it, but I don't have time
to right now. One of you might. It's
finished and is here:

I found a bug in a limit evaluation:
sage: f = sqrt(1-x^2)
sage: g = diff(f, x); g
-x/sqrt(1 - x^2)
sage: limit(g, x=1, dir='below')
+Infinity
It's a semicircle, so the derivative should go to negative infinity on
the right side.
I'd file a trac ticket, but I'm not sure if this is know

Hello,
Last week my new computer arrived. It has a Core 2 Quad CPU, 4 gigs of
RAM, and is very shiny. Unfortunately, I've had trouble compiling and
testing Sage with it. :(
I can compile 3.1.2 (using pbuild and make -j4 was problematic, but
we'll save that for later), but when I run 'make test',

Choosing a compatible advisor is very important, and if working on
open-source/free software is important to you then you should bring up
the issue very early on.

That's great - if it could run under mod_python, that would be even

I completely agree with others who have responded. Just wanted to add

If you are interested in computing intensive areas, then you might

Bad news for the accomodation in Nancy:

Hi,
3 minutes is unbelievably short. However, since you asked for suggestions, here
are some things that would be good to get across:
- programming in Sage is programming in Python; no need to learn some arcane
custom-built language in order to use Sage and contribute to it
- the development mo
