[GSoC] [BioRuby] GSoC week 2 status report

[John Woods]

If I can just suggest, there's a startup pitch out there which was formerly
known as Happy Science Coding, now Appsoma, which lets you run Ruby code on
Rackspace instances.

It may or may not be appropriate for what you want to do. It's not EC2, but
it is a VM (right?).

It's still a bit buggy with Ruby. If you have trouble, email Zack (see the
"About us" page). He's fairly responsive.
