Hi Sage-Devel, I intend to be at the Winter Joint AMS meetings in San Diego in January 2008. I have rented a "first timer's" exhibit booth for SAGE for $400 (all other booths cost about $1500). If you're very likely to be at the AMS meeting, let me know, so we can make a schedule of people who ca

I've been working on a from-scratch implementation (attached). Right now it runs a faster than Ralf Stephan's part.c, but not as fast as we would like. (And it seems to work, although I can't guarantee that right now.) On my Core Duo 1.8 ghz , it computes p(10^8) in about 17 seconds, compared to

Hello Pyrex List and Sage-devel, I've released Cython-0.9.6 at http://www.cython.org/. I hope Cython can be thought of as a "bleading edge" derivative of Pyrex (not a fork). Cython has a specific longterm goal of being included in the main distribution of Python. The main changes from the pre
