Noobkit is a seriously awesome resource for Rails developers — a searchable archive of all the various pieces of Rails (ActionPack, ActionMailer, ActiveRecord, etc) as well as a variety of popular Gems — like Hpricot and pdf-writer. Probably won’t end up being a replacement for using ‘gem server’ on your local machine when you need to, but the Rails docs and the Del.icio.us link roll are making this site kind of a first stop for me when looking for new Rails knowledge.

I’ve even wrapped it in a site-specific browser using the very cool Fluid tool for creating small, web-kit based browsers for your favorite sites. At this point, I’ve got one for our company’s instance of Trac, one for my personal projects on Lighthouse, and one each for Basecamp and Campfire. For icons, there’s a big set on Flickr.
