Review : OpenShift Cookbook

Filed under: java — Rahul Sharma @ 9:44 am

Sometime back I reviewed “OpenShift Cookbook” written by my friend Shekhar Gulati.I am tempted to write about it because it is a great cookbook which is aimed at people with no particular background. Openshift as a technology is not just for the enterprise but it is also for the developer if (s)he is learning new things or trying to build something for fun. (more…)

Few days back Apache Hadoop Development Tools a.k.a. HDT was released.  The projects aims at bringing plugins in eclipse to simplify development on Hadoop platform. This blog aims to provide an overview of few great features of HDT.

Single Endpoint :

Developing Eclipse plugins

Filed under: eclipse, java, maven — Rahul Sharma @ 8:49 pm

Recently I started working with team on a Eclipse plugin. The team had developed an awesome plugin that does the intended purpose. Thus I checkout the source and tried building it. The project source contained all the required libraries and it could only be build in Eclipse. In today’s world of continuous delivery, this is a major impediment as such a project can not be built on Jenkins. (more…)

Using Postgres JSON

Filed under: java — Rahul Sharma @ 3:03 pm

The applications of today are trying to persist data that has no fixed definition to it like user actions, application responses etc. Since the data is varied in nature the developers pick the Nosql paradigm to keep track of it.Often applications are spring based and spring has awesome support for Mongodb so developers start using Mongo db. Thus now there are multiple databases in the same application and there are overheads of working with the them. The admins have to keep track to two sets, the devs have to keep track to different pojos to make references etc. But do we really need to go down this road ?  I am ardent follower of  Postgres, so if we are using Postgres as the application store I will advise against going this road.

Junit Recepies : Having common Setup and Teardown

Filed under: Agile, java — Tags: , — Rahul Sharma @ 7:56 pm

The other day I was refactoring one of our apis. We were removing some of the columns as they were not required. I believe in this exercise dropping the column was the most easy part. After that I removed the corresponding fields from the associated ORM and it was fine for the business related code.  But !! the big one, was my code was not compilable, as the object was being used in a lot of tests and thus my project was all painted RED.

While I was fixing all the required tests I realized most of the tests were on similar lines. We were pushing some data in tests, creating some required resources and then destroying them after the tests were done. Now we have blatantly copied the stuff in every testcase  with total disregard to the DRY principle. (more…)
