I have been working on Linux for almost 3 years now and have grown to love it a lot. As with every linux user, the .bashrc file becomes cumbersome and difficult to maintain over a period of time, since there are a lot of project specific aliases, paths, etc So after working on a couple […]
Annotations really provides a whole new view of programming things. Groovy also provides some of its own annotations one of them is Category. Lets take an example of using it. We create a IntegerUtil class and annotate it with Category. [java] @Category(Integer) class IntegerUtil { List<Integer> multiples(Integer upto) { (1..upto).collect {this * it} } } […]

Hi guys, Recently as part of a project, I had to populate a SQLite database with large amounts of data pertaining to a number of classes requiring more than 5000 inserts and updates per class. I created a new SQLite database using Groovy’s Sql class. The initial strategy involved creating prepared statements and executing individual […]

I created a parent class for all command object classes to accept the common properties and created individual command object classes to accept […]
Most of us have experienced how important the Unit test cases are for our code base. I feel the other thing that is equally important, is the speed at which we can write the unit test cases. In Unit Testing, initializing different objects in setup of the test case (e.g., while testing a method which […]
Hi Folks, Recently I came across a cool way to compare differences between two branches, two tags, or between two commits on Github. Many a times in our project we have to thoroughly see what has been a specific change in the code base before we push it on our production branch. Here is how […]
