[sage-devel] Organizing sage days

2011-10-24 Thread mmarco
It is possible that i could get some funding to organize a workshop, which must be related to aplied and computational algebraic topology. I thought about organizing a sage days devoted to braids and/or knots and links; maybe with sprints aimed at the implementation of free and finitely presented

Hi all, This is pretty trivial, but hey, sage-devel is a bit slow recently :) Shouldn't we have mention trailing whitespace somewhere in the developer's guide - namely telling people to omit it? Having such a policy makes for cleaner revision control, as most agree (for example, at some point

Over on the zeromq mailing list, there was a post about running zeromq through tcpcrypt [1]. This seems like a good idea for our single-cell server, which uses zeromq to communicate between server and workers. It also seems like it might be nice to support it for sagenb.org, etc. My
