[sage-devel] Community thanks

2011-01-06 Thread mhampton
The Sage booth at the joint mathematics meetings is going pretty well, and I think it was worth doing. It is very useful for advertising our existence, capabilities, and future plans. Many people stopped by to express their appreciation for Sage and the efforts of its developers. I think that in

[sage-devel] Updated MPI

Hi all! I needed them for a seminar project, so I updated the openmpi (see http://trac.sagemath.org/sage_trac/ticket/8537) mpi4py (see http://trac.sagemath.org/sage_trac/ticket/8538) packages and the mpi4py docu (see http://trac.sagemath.org/sage_trac/ticket/10566). The packages worked on ubuntu

I was also wondering about this. I think a lightweight binary distribution without the entire devel directory could be useful (of course as an alternative to the existing binary download). It would decrease the download size dramatically. I imagine that the reason this is not done is so developmen

Thanks for your advice, Simon. Sounds like sage.rings.polynomial.multi_polynomial_ideal.MPolynomialIdeal would be a good class choice. I do have a trac account ('araichev') and have read about patches but have not actually submitted one yet. So i'll get on that by submitting my simple alg_dep me

I created a binaries package for the use in a Live CD with the commands export SAGE_FAT_BINARY="yes" make ./sage -bdist x.y.z-fat Testing seems ok (I am still unsure about sage -testall --optional, see http://groups.google.com/group/sage-support/browse_thread/thread/d3ffa3501849162b). Now I have

2011-01-06 Thread Nils Bruin
How much work would it be to change PARI/GP so that the GP compiler is accessible via a PARI library call? Then it would be possible to mix libpari use with gp script snippets and avoid pexpect-ing GP entirely. I don't know how much havoc gp-programs designed to run alone would wreak on PARI's glob
