Juggernaut by Alex MacCaw
The Juggernaut plugin for Ruby on Rails aims to revolutionize your Rails app by letting the server initiate a connection and push data to the client. In other words your app can have a real time connection to the server with the advantage of instant updates. Although the obvious use of this is for chat, the most exciting prospect is collaborative cms and wikis.

paginating_find by Anonymous
It's a plugin to help clean up and clarify pagination code in your Rails application. After you've got the plugin installed, you can use it to transparently load batches of model objects using just one call to the #find method. It's equally easy to use the plugin for stepping through data via your app's UI, or loading large numbers of model instances little-by-little, to avoid consuming a ton of memory.
