With ActsAsTaggableOn, you can tag a single model on several contexts, such as skills, interests, and awards. It also provides other advanced functionality.

AASM is a continuation of the acts-as-state-machine rails plugin, built for plain Ruby objects.

Paranoia is a re-implementation of acts_as_paranoid for Rails 5, 6, and 7, using much, much, much less code. You would use either plugin / gem if you wished that when you called destroy on an Active Record object that it didn't actually destroy it, but just "hid" the record. Paranoia does this by setting a deleted_at field to the current time when you destroy a record, and hides it by scoping all queries on your model to only include records which do not have a deleted_at field.

This "acts_as" extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a "position" column defined as an integer on the mapped database table.

attachment_fu is a plugin by Rick Olson (aka technoweenie http://techno-weenie.net) and is the successor to acts_as_attachment. To get a basic run-through of its capabilities, check out Mike Clark's tutorial http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu.

Rails gem to allowing records to be votable

acts_as_follower is a Rubygem to allow any model to follow any other model. This is accomplished through a double polymorphic relationship on the Follow model. There is also built in support for blocking/un-blocking follow records. Main uses would be for Users to follow other Users or for Users to follow Books, etc… (Basically, to develop the type of follow system that GitHub has)

Overrides some basic methods for the current model so that calling #destroy sets a 'deleted_at' field to the current timestamp. ActiveRecord is required.

Some [hopefully] useful extensions to Ruby's String class. Stringex is made up of three libraries: ActsAsUrl [permalink solution with better character translation], Unidecoder [Unicode to ASCII transliteration], and StringExtensions [miscellaneous helper methods for the String class].

Gemstash acts as a local RubyGems server, caching copies of gems from RubyGems.org automatically, and eventually letting you push your own private gems as well.
