    Ruby on Rails is a great RAD framework. We use it all the time. But one place Rails loses its magic–while not the fault of the framework itself–is with external integrations to legacy systems.

  • Asset Tracking Webapp Written In Ruby On Rails

    Here (PDF , Keynote) are the slides from my Phoenix Ruby Users Group presentation yesterday on Ruby P2P Development with Journeta. Thanks a ton for the great audience.
