At RailsConf, Chad Fowler and colleagues introduced gitjour, a RubyGem that facilitates serving and cloning git repositories using Apple's Bonjour protocol. This tool allows users to easily share and access git projects over a local network. During CabooseConf, the author successfully utilized gitjour to clone a project called embedded_actions, demonstrating its practical application for collaborative coding environments. Created by Chris Wanstrath, also known as @defunkt, gitjour enhances local network git interactions by providing a straightforward method to list and clone repositories.
