While working with Google charts, we usually face issues with long labels on the horizontal axis. The chart displays well, however the X-axis labels are not completely visible and displays the numbers like this: 24/3.. 25/3.. 26/3.. 27/3.. 28/3.. 30/3.. 31/3.. instead of 24/3/2006, 25/3/2006, 6/3/2006, 27/3/2006, 28/3/2006, 30/3/2006, 31/3/2006 The usual practice that we all apply is […]

There are lots of ways to validate a web page like HTML5 validations, but why not do it in a better interactive way by using AngularJS.

The following methods are :- slice() substring() substr() All these methods extracts parts of a string and returns the extracted parts in a new string. […]

As everything was going good in the development, so I pushed it to QA after which I was bombarded with JavaScript errors and missing providers. What has happened??

Introduction to SonarQube: We all are well aware of the importance of codebase quality, unhampered of “deadly programming skills” which can wreck our code. But isn’t it quite cumbersome to implement different tools to look upon its different aspects. What if in one place, we can have detailed insight of all the development sins. This […]

Atomic means all or nothing – either everything succeeds or all fails. Git is known to have atomic operations i.e. an environment issue will not cause git to commit half of the files into the repository and leave the rest. So what are we doing talking about atomic commits when all operations are already atomic in […]

At times we come across few cases where we need to differentiate the links amongst the plain text. Angular provide us with a very useful filter named : “linky” which help us to do so. With the help of linky filter we can detect links from text and show them differently .  Linky takes text and produces HTML by […]

In this post, I will present a technical “deep-dive” into Spark internals, including RDD and Shared Variables. If you want to know more about Spark and Spark setup in a single node, please refer previous post of Spark series, including Spark 1O1 and Spark 1O2. Resilient Distributed Datasets (RDD) – An RDD in is primary abstraction […]
