Hazelcast + Kibana: Best Buddies for Exploring and Visualizing Data

,

A lot, if not all, of data science projects, require some data visualization front-end to display the results for humans to analyze. Python seems to boast the most potent libraries, but do not lose hope if you’re a Java developer (or if you’re proficient in another language as well). In this post, I will describe how you can benefit from such a data visualization front-end without writing a single line of code.

Lesson Learned on Groovy

,

Though I have worked on Java for more than a decade, I have not had a chance to work on Groovy. While working for API Integration into Jenkins CI/CD pipeline, I extensively used Groovy to invoke REST API, validate the user input parameters, and business logic for that.

Why Is Groovy Easy for Java Developers?

It allows to use the Java syntax liberally and tries to be as natural as possible for Java developers. It is an object-oriented dynamic programming language for Java virtual machine (JVM) and can be integrated smoothly with any Java Program.
