Ruby on Rails

Ruby on Rails is an open –source web application frame work that is optimized solution for all the web applications. Rails web frame work is an integrated framework that utilizes the dynamic nature of the object-oriented Ruby programming language. Rails web frame work is an extremely productive framework for database-backed Web applications.

Rails developers emphasize features of the framework for productivity rather than tools, and they take a common approach to Web architecture that will satisfy the needs of a large portion of the Web application projects in the wild.

Rails - being an MVC web framework; amazingly integrates models, views and controllers to lighten the configuration task.

RailsKit

Rails Kits is here to bring you great ready-made Rails code for you to use in your projects. More than just plugins, these starter kits can act as the foundation of your new Rails application. You can save hours of time, skipping the boring stuff and diving right into the code that makes your application different from all the rest.

RailsKits provides ROR developers with tools to speed up their projects. The first product offered by this site is a starter kit called the SaaS (Software as a Service) Rails Kit, which provides a complete subscription management and recurring billing solution, as well as credit card management, for hosted web services. The Rails Kit provides developers a foundation on which to base their new Rails project, so they can skip over writing those basic codes and instead focus on developing more advanced or unique stages of their project.

Ruby Facets

Ruby Facets is a large collection of libraries for the Ruby programming language. Ruby Facets is the single largest collection of general purpose method extensions and system additions for the Ruby programming language. Ruby Facets is the single largest collection of core extension methods and standard library additions available for the Ruby programming language.

The CORE extension is a large collection of methods which extend the core capabilities of Ruby’s built-in classes and modules. This collection of extension methods is unique. The methods are generally stored in individual files so that each can be required independently. This gives developers the potential for much finer control over which extra methods to bring into their code.

The MORE additions are a collection of classes, modules and lightweight systems which constitute an ever improving source of reusable components. This set of libraries is kept light and focused on useful to a wide variety of usecases.

Facets is true open source software! Ruby Facets is distributed under the terms of the Ruby licence, just like Ruby.

JRuby

A multipurpose language that focuses on simplicity and productivity, it combines the best features of many compiled and interpreted languages, such as easy development of large programs, rapid prototyping, almost-real-time development, and compact code. Ruby is a reflective, dynamic, and interpreted object-oriented scripting language, and JRuby is a Java programming language implementation of the Ruby language syntax, core libraries, and standard libraries.
Java implementation of Ruby language started in 2002.

Its open source and has many implementations

●100% Java implementation of Ruby

●Open Source, GPL/LGPL/CPL licensed

●Not yet a Ruby-to-bytecode compiler

●Native-threaded

●Runs on Java SE versions 1.4.2 or higher

●Started in Fall of 2001 based on Ruby 1.6

With JRuby you get the best of both worlds: Ruby applications and libraries, plus Java libraries. And you can access those libraries with Ruby syntax (or Java syntax, if you want).On average JRuby, runs 2 and a half times faster than Ruby, except at startup.In addition to native threads, JRuby supports Unicode natively.
