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 Creating tables in Sage Math Cloud
Evidently, MathJax doesn't support the tabular environment: github.com/mathjax/mathjax-docs/wiki/LaTeX-Tabular-environment

comment Mathematical software wish list
Hi -- purple sage didn't work due to lack of time. Regarding dumping useful code on us, that we have to understand and get up to snuff for inclusion, if we had more time and bandwidth, then we would make that easy. However, we don't -- I have almost not grant support, and almost all effort is researchers in their spare time. Maybe if we someday have funding...

comment How do I automatically restart a GCE preemptible instance?
Regarding "Preemptible instances are available from a finite amount of Compute Engine resources, and might not always be available." during the last two weeks there have been several days when no preemptible instances (of any size) could be started in the us-central1-c zone. That's just my personal experience. The caveat in the docs should be taken very seriously.

comment Command in sage worksheet (in sage math cloud) to get anything in sage?
@kcrisman -- I didn't mess everything up! I mainly "change" SMC by adding new things. I try hard to make sure everything still works, and care a huge amount about backwards compatibility. Also, the "way things work" in Sage traditionally is already what I think is right, so I tend to stay with it.

comment vim in 14.04 (Trusty) starts up in Replace mode
I've tested running vim (the command line version) after switching to vim-gnome, and it definitely does not fix this problem.

Hi -- I definitely misunderstood your question. I agree with Alex Ryan's answer below.
