• jQuery - The de-facto library for the modern age. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.
• Backbone - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.
• AngularJS - Conventions based MVC framework for HTML5 apps.
• Underscore - Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.
• lawnchair - Key/value store adapter for indexdb, localStorage

• rabl - General ruby templating with json, bson, xml, plist and msgpack support
• Thin - Very fast and lightweight Ruby web server
• Unicorn - Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels.
• SimpleCov - SimpleCov is a code coverage analysis tool for Ruby 1.9.
• Zeus - Zeus preloads your Rails app so that your normal development tasks such as console, server, generate, and specs/tests take less than one second.
• [factory_girl](h
