The obvious need today is to go with the flow of technology as aggressive web applications are being produced here and there. Ruby on Rails has been identified as the best interface software that programmers look forward to today since it simple yet great output makes the world of programming all the more simpler.



You can really install it on any software even on your Windows XP or Vista. With all the ideas of new developmental software up in the air, you can just imagine how many programs from people can be seen after some time especially once they have settled in and mastered this program.

There are several alternative implementations and completion of the Ruby language as of 2008 including JRuby, Rubinius, IronRuby and YARV. Each of them has different approach especially that JRuby provides just-in-time compilation functionality. JIT or just-in-time compilation is also known as Dynamic Translation. In computing, it is a system and a technique for improving runtime performance of a computer program. It has two earlier ideas in run-time environments such as dynamic compilation and bytecode compilation. Its advantage over statically compiling the code at development time is that it can recompile the code and its ability to enforce security guarantees. Hence it can merge a few of the advantages of interpretation and static compilation.

JRuby, YARV, Rubinius, and IronRuby are some of the alternative implementation of the Ruby language as of 2008 with each of them taking a diverge approach.

• JRuby – One of the strong features of JRuby is its capacity to invoke the classes of the Java Platform considering that it is a Java implementation of the Ruby and is closely incorporated with Java.

• YARV – an acronym for Yet Another Ruby VM, it is a bytecode interpreter developed for the Ruby programming language with the goal of trimming down the execution time of Ruby programs

• Rubinius – it is clean, understandable code that is easy for users to comprehend and extend. It is a virtual machine and compiler for Ruby.

• IronRuby – an approaching implementation of the Ruby programming language that targets Microsoft .Net framework

One of the Ruby on Rails fundamental principle is “convention over configuration.” It aims to reduce the number of decisions that developers need to make as it gains simplicity but not losing flexibility. The simple phrase implies that a developer only needs to indicate alternative aspects of the application. When the convention implemented by the tool you are utilizing equals your desired behavior, you take pleasure in the gains not even having to write configuration files. When your desired behavior digresses from the implemented convention, then you configure your desired behavior. The programmer can work at a higher level of abstraction with all this configuration free approach to programming.

Also known as Single Point of Truth, “don't repeat yourself” or DRY is a process philosophy seeking to reduce duplication especially in computing. This philosophy stress on that information should not be duplicated because it makes the change more difficult, it can lessen clarity and may lead to inconsistency. DRY is from Andy Hunt's and Dave Thomas' principle in the book of Pragmatic Programmer. A revision of any single element of a system does not alter other logically-unrelated elements when the DRY principle is effectively applied. Moreover, elements are kept in sync because elements that are logically related all change predictably and evenly.
