1. There is a public mathematica language parser (version 3.0
mathematica) that I wrote in common lisp.
WRI knows about it, inquired about it, made various claims. I
disputed them. They went away. This apparently

Here is a LiveCD (Ubuntu based) of 3.1.1, if anybody

A few days ago I spent a couple of hours getting PyObjC working with
sage. The objective was to be able to write little sage-based GUI
applications. (Though it could easily turn into a full-blown sage.app
IDE, that was outside the scope of 2 hours playing around.)

Looking at factorization.py I was all ready to fix all the problems I
could see -- using Sequence to get a common universe for the bases on
construction, cache this base_ring, only allow operations between
factorizations with the same base_ring, and so on.

I just created ticket #3927 and added a couple of patches implementing
a few functions for the Factorization class (division, gcd and lcm).
These are orthogonal to the problems discussed at #2460, but I may
have a go at resolving those issues as well.

Hi,
do you think it would be a good thing to add a link to Sage wiki on

Some part of the wiki are not developer-specific and are valuable to

Couldn't stop myself from showing how that would work in Maple,

evalindets(data,negative,0);
