Re: [sage-devel] overhead in creating p-adic elements

2010-08-14 Thread David Roe
So, I haven't looked at profiling for p-adics for quite a while. But one way to speed up this kind of item creation is to implement a morphism from ZZ to Qp and then write a super-fast _call_ method. I can't do it right now, but I can provide advice if someone else wants to. David On Fri, Aug

Another option would have been installing from the Ubuntu Minimal CD, that way you could install only the strictly necessary packages. Indeed, if the Sage notebook can be accessed from outside the virtual machine, you could even get rid of the X environment, and have sage - notebook running on a

[sage-devel] license question

2010-08-14 Thread mhampton
I'm thinking of making an optional package for the program Qhull, which computes convex hulls and Delaunay triangulations numerically in any dimension. I am more motivated to work on it if it could someday become a standard package, so my question is whether its license is compatible with Sage.

I have nothing to say about the license questions, but I did put together a spkg for TOPCOM and some sage code to interface it at http://trac.sagemath.org/sage_trac/ticket/8169. Since both Qhull and TOPCOM deal with aspects of triangulations of the convex hull of a point set it would be nice to

That makes sense; I just tried your spkg and ran into some problems which I put on the ticket. I'd like to make it easy to use alternative convex hull programs for polyhedrons (qhull and lrs being the first examples). On Aug 14, 10:06 am, Volker Braun vbraun.n...@gmail.com wrote: I have nothing

I suspect that many of these issues would be resolved by using Maxima directly, using one of the graphical interfaces (e.g. wxmaxima). -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com
