Ruby on Rails is an open source web application framework for the Ruby programming language. It is specially designed to be used by the web developers for rapid development. Like many web frameworks, Ruby on Rails uses the Model-View-Controller architecture pattern to organize application programming. It includes tools that make common development tasks easier. If you follow the correct conventions, you will be able to avoid lengthy configuration of files and you can have more time to focus on business logic.

If you are a developer, here are some useful points I would like to share with you. These points will help to make your jobs easier.

• Rails has a well-defined plug-in structure that allows the users to install and use plug-ins in the application easily. David Heinemeier Hansson, the founder of Rails stated that he used 5-6 plug-ins in each Rails application. Being the developer, you don’t need to waste your time writing the program. You just need to make use of the written plug-in available in the market that provides the functionality you require. You can also dump or load data by issuing a Rake command. You can examine the data you need easily.

• In order to increase our work efficiency, we need to make sure that the program is able to run smoothly. When you are working with Rails, you will be able to do “automated testing” to ensure that you do the right things. This testing helps to improve your workflow and increase your confidence in the results.

• As all of us are aware, projects often include more than just application-specific code. We need to create sample data and we need to move files. Web services have to be queried and codes need to be rewritten. By applying Ruby on Rails, the developers can save a lot of time solving these common problems.

• Rails runs on top of Rack. Rack makes it possible to mix and match between Ruby web frameworks and servers. For developers who are using a framework that supports Rails, they can choose from any of the servers such as Mongrel, Thin, Phusion Passenger, etc. to match with it.

• In some situations, the developers may have code that they are curious about. They may not know what the output is. By applying Rails, you can make use of its wonderful tool called console. By running console, you will be able to access your Rails code in an interactive way. You can peek at your data quickly without logging in to the database.

Combining Perl-inspired syntax with features like those of Smalltalk, Ruby is a dynamic, reflective, general purpose object-oriented scripting language. It was developed and designed on February 24, 1993 by Yukihiro “Matz” Matsumoto in Japan. Perl, Smalltalk, Eiffel, Ada, and Lisp are the languages that it is based on.

Including object oriented, functional, reflective, and imperative, multiple programming paradigms are supported by the script. Moreover, it has an automatic memory management and dynamic type system, which makes it analogous to CLU, Perl, Python, Dylan, and Lisp in varying respects.

C was used to write the implementation of the standard 1.8.7, as a single-pass interpreted language. At present, no specification of the language exists, and hence the de facto reference is its original implementation. As of 2008, several of its alternative implementations have arrived including YARV, JRuby, Rubinius, IronRuby, and MacRuby. Each of its alternatives takes a special approach while just-in-time compilation is provided by JRuby and IronRuby. YARV is used by the official 1.9 branch. Version 2.0 which is in development is said to be using this also and is said to be finally superseding the slower MRI of the language.

The concept that gave birth to the script was that there got to be a scripting language that balances functional programming with imperative programming. According to the designer and developer, Yukihiro, a scripting language that was more object-oriented than Python and more powerful than Perl was what he was looking for. And so he ended up creating the script. Yukihiro has stated that he designed the language from programmers’ point of view as he believes that systems design should give emphasis to human needs more than computer needs. So, he followed the principles of good user interface design, and as a result it not only enhances a programmer’s productivity, but most programmers find working with it a fun, cool thing.

Rumor has it that Ruby follows the principle of least surprise (POLS) – the language behavior that minimizes confusion for experienced users. However, in a May 2005 discussion on the comp.lang.ruby newsgroup, Yukihiro tried to detach the script from POLS. Besides, he has stated that he had not applied the principle of least surprise to the design of the script. In spite of this, the script seems to be believed following POLS among some programmers.

Features of Ruby:

Following are the features of the script:

* Object-oriented
* DLL/Shared library dynamic loading on most platforms
* Six levels of variable scope:
o global,
o class,
o class instance,
o instance,
o local, and
o block

* Exception management
* Methods can be called without parentheses, making Ruby trendy for putting into operation Domain Specific Languages
* Automatic garbage assembling
* Iterators and conclusions
* Indigenous, Perl-like standard terminology at the language level
* Operative overfilling
* Greatly portable
* Two-way multi-threading on all platforms by means of green threads
* Introspection, reflection and meta-programming
* Big standard library
* Sustains reliance injection
* Sustains object runtime modification
* Continuance and initiators

Although Ruby has partial support for UTF-8, at present, it lacks full support for Unicode.

Ruby is a dynamic script that released by a Japanese programmer called Yukihiro Matsumoto. It is an object-oriented programming language that can be program for all sorts of operations like processing text files to system management. It is a simple yet straight-forward language. Above all, it is an open sourced language.

It is not easy to explain how Ruby operates to those who lack the technical knowledge due to the nature of this language. However, there are plenty of user friendly tools out there to help those who are less tech-savvy when it comes to sing Ruby.

The popularity of Ruby amongst programmers is due to the fact that it is a pure object oriented language. It is a very well- organized language and is easily understand when users learn to use it. With it, there is no use of syntax but the use of a more conventional file source code. Although simple, it is a very powerful and flexible programming language.

One of its best features is he Interpreter Shell that allows programmers to experiment with the language by viewing and evaluating the efficacy in real time when the task is assigned. Programmers can avoid the lack of efficient by editing and testing as they proceed with their steps one by one. According to the creator, he says that this programming language is designed to solve problems and not to complicate things.

Here is a list of features that you will get when you use Ruby with many of the scripting language that programmers use nowadays like ADA, C++, CLU, Eiffek, LISP, Python and Smalltalk.

• Multithreading
• Mix-ins
• Singleton Methods
• Exception Handling
• Fully-integrated Closures and Integrators
• Automatic Mark-and-Sweep Garbage Collection
• Proper Meta-classes (or Meta-Classes)
• Fully regular expression support
• Functions that give access to the operating system running Ruby
• Fully-featured Debugger.

There are different kinds of scripting languages available on the Internet which are used for designing various kinds of websites. Similarly, you can also find software which cost you money before you actually use it. On the other hand, you will also find software on the Internet meant for free access.

Open source web development software is free for use. At any time you can download it from the Internet, process it the way you like it and thus, have a website completely based on an open source web development techniques. There are many flexibilities provided by this software like one can do editing according to one’s wish, it is also open for coding by web developers as well as weaving of web pages becomes completely easy.

LAMP is one of the applications used by most of the open source web development companies. If you are planning to make a website then you can give a try to the services offered by open source web development companies which basically use LAMP technology. LAMP consists of Linux-OS, Apache-Web Server, MySQL-Database Server, PHP-programming language. Some of the examples of websites built with the help of LAMP technology are Amazon book store, yahoo store as well as many other international social networking sites.

On the Internet you will come across infinite websites in which you do not enjoy the content management system. If the content management is poor then users would not be able to freely use the content like videos, files, documents, audios etc. It creates hindrance for you website to convert the visitors into real customers. However, with open source ecommerce website development applications you will enjoy a well integrated content management system. If you have a network of users, web developers and programmers then you can let them work on open source software to create a unique website that places your online business on the zenith of success.

Over the past few years open source software, web platform and technologies have taken stake of web development and web application development. With Ruby on Rails hype in IT industry we have seen proportionate increase in performance and scalability problems. Ruby on Rails was extracted from Basecamp by David Heinemeier Hansson, is a framework for web application. Ruby on Rails development India offers Ruby on Rails offshore outsourcing web development and is based on open source web platform, LAMP. Ruby is object oriented programming language, it is blend of different languages – it has taken concept from Smalltalk, ease to use from Python and reality and flow from Pearl. Rails is well stack, comprehensive open source framework for developing database supported web applications, dynamic websites using model view controller (MVC) methodology.
With your database and web server, the Rail web development environment helps you develop complete, simple web application with rich functionality and interactivity. Because of the flexibility it provides Ruby on Rails is well suited for e-commerce development, content management, oscommerce, collaboration and online social communities. Since Rail works well with wide range of web servers and databases it is really easy to deploy web solutions using Rails.

Ruby on Rails (RoR) development main features include Model View Controller architecture that separates data from logic i.e. presentation layer and helps in organizing application program. RoR database access library simplifies data handling. Rails framework consists of extensive AJAX library, Ruby uses this library to generate AJAX code and the required Java script is automatically generated.

Let us discuss in brief Ruby on Rails framework, it includes following packages: ActiveRecord, ActiveResource (Active Web Service Package), ActionPack, Active Support, ActionMailer. These packages can be customized by adding plug-ins and extending existing functionalities of these packages.

As per official page :

“Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern. From the Ajax in the view, to the request and response in the controller, to the domain model wrapping the database, Rails gives you a pure-Ruby development environment. To go live, all you need to add is a database and a web server.”

Ruby is a programming language… as per the official page it is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Official About Us  page, have very interesting  facts about Ruby.

We at this will try to add some value to the programmers who are working in Ruby or just thinking to do programming in Ruby.
