Ok, good to know. A good test would be to continuously build numpy + scipy on top of it ASAP. Do you think cython (or is it sage) could donate some CPU resources on the cython CI server for numpy ? I could spend some time to make that work, cheers, David > > Dag Sverre > _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > http://mail.scipy.org/mailman/listinfo/numpy-discussion > _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
