Knoboo is similar to the Sage notebook but looks more likey Mathematica and uses xmlrpc. To try it out: 1. Type sage -optional to see what the package name is. 2. Type sage -i knoboo-20080411 to install (or whatever the latest name is). 3. Type sage: !knoboo to try it out. Be sure to not have something running on port 8000 when you do this.

Hi,
I'm just starting to write a book on Sage for an undergrad course.
It's supposed
to have a narrative and personal feel, much more so than the
tutorial or other
books. I guess it's a little like Sage for newbies except (1) aimed at
senior
undergrads with a programming background, and (2) will be finished by June
at the lastest.I'm posting it here as I write it:

What follows is a list of typos I noted, and just a few comments.

p.8:
* start the notebook by typing ./sage -notebook /// example does $

throughout section 1.1.2
p.12:
- WinSCP Using WinSCP /// missing period
