Ruby on Rails have been used for developing powerful Ajax based applications nearly as early as the programming technique was introduced. The rapid improvement of Ruby on Rails along with other frameworks have allowed developers to build client side applications with relative ease. Functions are already laid out by Rails and developers just have to...
Ruby on Rails like most programming languages will only provide developers with the tools to build an efficient application. Everything is still left to the developer’ s hands security speed of processing and user interface.

Testing is a very important component in applications development. Developers spend a lot of time and effort in testing their applications which could even take more time compared to the development process. The efficiency of the application will only be known if the application will be constantly tested. Testing is also implemented for the security...
Security should be the top priority of every application. Without security personal information and highly sensitive data will be exposed extracted and could be used for malicious purposes. A single attack could easily destroy not only the application but everyone related to the application developers will lose their reputation clients will...
Routing is one of the features in Ruby on Rails that are not extensively used by most developers for a good reason. Routing is necessary in some applications and in most cases routing is a bit challenging to integrate in Ruby on Rails. There are still options which are relatively easier compared to routing. But when routing...
Ruby on Rails is one of the easiest programming applications in developing rich internet applications. But like most programming languages configuring Ruby on Rails is not a walk in the park either. Ruby on Rails were able to harness the power of Ruby programming language by creating a framework out of it. With the help of the built-in applications...
Ruby on Rails is a framework that also supports development of plug-ins. The ability to build plug-ins is a great feature in Rails since this will enable developers to build additional tools that could be integrated in the application. Plug-ins could be used for better user experience security and optimization of functions. Even if the application...
Caching in Rails is easy since the framework has some built-in functionality for this action. Developers do not have to look for 3rd party applications to efficiently cache their applications. Although a 3rd party caching tool is still a possibility understanding cache in rails will deem the 3rd party applications unnecessary. After years of updating...
Implementing Database Migration on Rails Ruby on Rails is often perceived as a framework for developing RIA Rich Internet Applications .

Generally in C program the function definition and calling takes the form as given below main int x y z; z sample x y ; printf d” z ; sample x1 y1 int x1 y1; int z1; z1 x1 - y1; return z1 ; Here what happens is the values x y gets passed to x1 y1 and the value z1 is calculated in sample function...
When a variable is not initialized in main function it contains garbage value. This can be well seen from the example below main int x; printf d” x ; z sample sample printf Testing program” ; Output is x 80 Testing program The above program prints a garbage value...
The default return value from a function is int. In other words unless explicitly specified the default return value by compiler would be integer value from function. When a programmer wants other than integer values to be returned from function then it is essential that the programmer follows the steps provided here below 1....
