Back in 2013, when I worked for the Federal Gov, JRuby was the best way to get Ruby on Rails apps to run in a Windows-only world. I absolutely love the work that folks like Charles do!
If you don't mine telling, were you a contractor or like a permanent dev? I'm very surprised that feds would choose Rails for projects. Maybe for prototypes or in house stuff or whatever.
Anyways, cool!
But, still very cool yeah!
