I've created a ticket for implementing latex(g) using tkz-graph at http://trac.sagemath.org/sage_trac/ticket/5975 I've spent some time with tkz-graph and it should be relatively straightforward to get some basic functionality implemented into Sage by building on this. John Palmieri has started

I posted the above before reading your reply about running gdb ... so just to be clear, notebook() crashes before Ctrl-C is pressed (but only when running in sage -gdb). On May 3, 10:36 pm, bbarker wrote: > Some additional information: > > Trying to exit the server during hang by pressing Ctrl-C

Some additional information: Trying to exit the server during hang by pressing Ctrl-C repeatedly will only yield the following (repeatedly): ^Cselect() error: Interrupted system call ^Cselect() error: Interrupted system call ^Cselect() error: Interrupted system call ^Cselect() error: Interrupted

Hi Michael, 1 and 2 are both outside of zones (they are in the "global zone"), and they also hang seemingly indefinitely (I haven't kept them running long enough to prove me wrong yet, other than the one running in the zone). Since it is happening on fairly different systems - SXCE (workstation/

Hello, I'm very happy about the improved Solaris support. Until recently I was running sage in a linux zone on my workstation, but unfortunately modern linux version support for branded zones is lagging. I confess I've also been using sagenb.org a bit (which will be running on a T2000 soon?) I

Hi Ondrej, No, I have not come round to publishing it yet in Comput. Phys. Commun. or some similar journal. The thought has occured to me that one could use the index functions for the 3j, 6j, and Gaunt coefficients for a much simpler storage scheme in python by using the index as a key for a d
