Roles UI is a graphic interface library for Ruby on Rails which provides the ability to manage roles and permissions in realtime for applications which use Cancan. It is a Rails engine, so it has its own namespace. You can reach Roles UI in /roles_ui. Roles UI consist of two main entities, Role and Permission. Each Role may have a permission set. Roles belongs to users. Roles UI extends your User model so you don't need to create this association. By default, Roles UI is configured to work with the User model.
RubyDNS is a high-performance DNS server that can be easily integrated into other projects or used as a stand-alone daemon (via RExec). By default, it uses rule-based pattern matching. Results can be hard-coded, computed, fetched from a remote DNS server, or fetched from a local cache, depending on requirements. In addition, RubyDNS includes a high-performance asynchronous DNS resolver built on top of EventMachine. This module can be used by itself in client applications without using the full RubyDNS server stack.
Rummy Pong is a mouse-driven browser game that features the ability for the player to score against the computer (and vice-versa) with color and number sequences, similar to the ones found in the card game Rummy. The player with the highest score is the winner after a certain point difference between scores is reached. Good reflexes and looking ahead always help, but the speed of the ball is adjustable via the keyboard.
