Colleagues, There is a cross-fertilization that might be very useful for both the Scientific Linux world and the Sage world. For those who don't know, Scientific Linux is a linux distribution that is a "common platform" for scientific users. It was recently described as: Sage is an open source effort to create a free and open alternative to Mathematica, Maple, Magma, and Matlab. It seems to me that the development of a standardized open source platform for science and scientific computation have quite common goals. Indeed, it could be argued quite strongly that this kind of a platform effort is a strong target for NSF, INRIA, or other major government funding. I can answer some trivial questions about both projects but I am not a "contact person" for either project. Tim Daly Axiom
