I do research on elliptic curves and modular forms and direct the Sage mathematics software project.

I am a professor of mathematics at University of Washington. In my mathematics research, I use the Birch and Swinnerton-Dyer conjecture as motivation to understand the constellation of arithmetic invariants associated to optimal quotients of J0(N). I also use do explicit computations with modular forms.

comment Using comma as a decimal mark with SageTeX
Just for clarification, is this the sort of thing you're asking to do? "Consider $\pi\sim \sage{str(N(pi)).replace('.',',')}$" It outputs in the wrong font though.

comment file size changes when using cp
Thanks for your comment. I just hit this when using cp on an XFS formatted file system, whereas things work fine on ext4. Time to reformat a lot of filesystems...

comment Derivative of Riemann Zeta at nontrivial zeros
And I made the database_odlyzko_zeta package (which is pre-installed into cloud.sagemath.com) using files from dtc.umn.edu/~odlyzko/zeta_tables

comment Simultaneous collaborative editing of a LaTeX file
cloud.sagemath.com now provides full shell access combined with a LaTeX editor, which is a powerful combination.

comment lxc containers hangs after upgrade to 13.10
I tried some basic commands with lxc containers in Ubuntu 13.10 on a clean 64-bit install, mainly using commands from the official documentation (help.ubuntu.com/13.10/serverguide/lxc.html). After creating about 5 containers, starting and stopping them a few times, etc., suddenly they started hanging, just as you describe above. I had to hard reboot the machine.
