The Jiva-est Hobo
Now for me and people of my generation when you start talking about Hobo the first thing we think of is a TV show from the late 70s, early 80s that featured a dog that was kind of a working class Lassie, wandering Canada saving the day.

Hobo means something a bit different in the Jiva office as it is at the core of Beanbag and the upcoming Advisr.
To quote HoboCentral.net
“Hobo is a plugin for Ruby on Rails that brings a number of extensions, some small some large, to Rails application development. The common theme to these extensions is rapid development.”
The Jiva team have been lucky enough to work with Tom Locke who is responsible for Hobo on much of the development of Beanbag and it really does enable a rapid development cycle that allows us to iterate quickly and keep improving the Beanbag site.
If Ruby on Rails is your thing or you are just interested in rapid development its well worth popping over to HoboCentral.net for a nose around.
