I just updated the zucker core extension library and it is now completely based on refinements. It is organized in very small units and playing around with it is a great way to get familiar with Ruby's new refinements!
The ruby_info gem provides a RubyInfo class that contains a lot of information about your current Ruby environment. Also, the source file is a good place to learn about the various global variables and constants that have special values.
PWS 1.0 has been released. It got new features on crypto level and tweaks in the command-line interface. I've also written a small blog post about my Ruby experiences I've had while implementing the gem.

Irbtools is a meta gem that installs useful irb gems and configures your irb. It's easy to use and much more fun than a vanilla irb ;) This latest release focuses on decreasing the annoying start-up time caused by loading too much libraries, so it offers multiple loading methods, including autoload and threads.

If you don’t know what to do on whyday, do not play code golf! It is frustrating! And it is addictive! And you don’t create something useful by golfing! But it is also fun! And I am not the only one who wants to squeeze code even more. The original Ruby 1.9 interpreter comes with pretty crazy version of itself: a version for code golfing!
has_many_booleans is an ActiveRecord plugin which creates virtual boolean attributes for a model. When the object gets saved, the plugin transforms all attributes into a single integer, using a bitset. So you can easily add new attributes without changing the database structure.
