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?? So here, Angular.js internal dependency injection was broken… 🙁 Since Angular […]

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 […]

Using lean() in mongoose provides high performance queries.

R is the most common platform for predictive analysis. Rattle library is an extension of R which takes the predictive analysis to another level. This blog is focused towards  people who have some experience in R. Rattle is the library provided for R language that is used for data mining process, where you can apply […]

Have you heard about RoboGuice? Well, don’t be surprised. It is now getting familiar like other things in Android development. RoboGuice uses Google Guice library, a simple framework and easy-to-use dependency injection to Android. Just think about casting a view using findViewById() and it is so necessary, for which you have a one new thing i.e. […]

“mappedBy” is a static map which is used to determine and change the way two associated domain classes interact with each other. Let’s start with the role of “mappedBy” in one-to-many relationships. Consider the following Example:- [code]class Team {     static hasMany = [members: TeamMember] }[/code]   [code]class TeamMember {     Team memberOf     Team captainOf }[/code] The Team […]

Prediction Analysis is the practice of extracting information from existing data sets in order to determine patterns and predict future outcomes and trends. There are various analytic and machine learning tool available in the market for predictive analysis. This post includes introduction of Knime followed by a sample use case of clustering using Knime and […]

Big Data in itself brings many challenges; as is the case with anything related to data. Predictive Analysis is one part which takes up much effort and attention as well. One of the foremost challenge which one comes across is how to get started with the “subject”. I would first like to highlight the basic […]
