collaboration for Developers to:
upside-down
• Freely host open source
projects and code
• Connect, Communicate,
Collaborate, and Code with
peers
• Eventually easily deploy
applications/services to
“clouds”

49. Endorsements had no reliability and
performance issues with
Glassfish
money is on JRuby (and
Look like the best Glassfish) for the long
deploying option I ever haul; if you haven't checked
found for Rails, GREAT! out Glassfish yet, you're doing
yourself a disservice!
nice way to deploy and
manage my app while leaving
things open for scaling
the easiest rails stack
in the world, jruby 1.2rc, rails 2.3rc, leading the way to simple,
glassfish v3 scalable, no-hassle hosting for
... Ruby web applications.
too easy to run jruby/rack/ ...
glassfish behind nginx it's true one-step deployment.
