Hi, I now have someone here at my company that is going to help maintain spkgs. We have a number of spkgs that i) SAGE currently doesn't have and ii) SAGE does have but we have updated or added bug fixes. A while back there was agreement on a new standard format for what the structure of an

I would be willing to chip in some effort on the mathematica.sage file, although not in the very near future. I plan to begin migrating my undergraduate courses to sage from mathematica for fall semester 2008. I hope to convince other faculty do to the same, but it won't be easy. I am mainly

Well the biggest reason is just inertia: my department has been using mathematica for years, and everyone has a full set of computer labs and handouts and demos already done in mathematica. Why learn a new system and have to port everything over? We don't even directly pay for the license as a

I got swamped by teaching, SAGE Days 4, SIMUW, and... buying a house this week (!), so I haven't been able to move anything forward. Fortunately, I have no formal responsibilities for the next two months, so a lot is likely to happen in the near future. Nice! My plan is to start working on
