Protein Structure determination aided by Stochastic Search (Replica Exchange Monte-Carlo Method)

Introduction Proteins are large molecules, which occur in abundance in every single living organism. They carryout vital functions such as transporting oxygen, converting the food you eat into energy your body can use, and many more. Proteins are long chains of linked units called amino acids. There are 20 types of amino acids. Proteins fold into different shapes depending upon their sequence of amino acids. Continue Reading

First steps to build Spring Boot Application with Couchbase

As the name of the blog suggests, we will be taking the first steps to build a simple application from scratch using Couchbase as a database and spring -boot as a framework. Let’s get started. You can create a starter maven project using this link. Add Web, Lombok and Couchbase dependencies. The pom.xml should look like: Let’s run the spring boot application: How to download Continue Reading

Monitoring Kafka with Prometheus and Grafana

Kafka monitoring is an operation which is used for the optimization of the Kafka deployment. This process is easy and efficient, by applying one of the existing monitoring solutions instead of building your own. Let’s say, we use Apache Kafka for message transfer and processing and we want to monitor it.But, before learning the steps for monitoring, let’s first understand the prerequisites. Kafka It is Continue Reading

Data processing using ML Supervised classification algorithm to find accuracy

Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it to learn for themselves. Type of machine learning Supervised learning Unsupervised Learning Reinforcement Learning In Supervised Learning, algorithms learn from labeled data. After understanding Continue Reading

Getting Started with Akka Remoting

When we start with Akka we generally start with one actor system on our local machine but when we talk about the business application we can have multiple parts of an application and those part can run on different machine or node. Akka Remoting is a communication module to connect the actor system in peer to peer fashion. It also serves as the foundation for Continue Reading

Tired off creating Grafana dashboards manually? Let’s automate it.

We have already discussed the creation of Grafana dashboards and alerts in my previous blogs. We were doing that manually. But think of, if we need to do that in more than 10 environments then we need to repeat that manual process again and again and sometimes we get frustrated by doing all these repetitive stuff. We should have some automated process for doing this. So Continue Reading

Why programming community should be serious about RUST

I have been exploring Rust from the last few weeks, as it has been declared the most loving language in 2018. As a Scala/Java developer, I worked on many applications, which were related to the banking domain, web applications, mobile applications, e-commerce, social media, etc. But I was not able to find what kind of applications should be built in Rust? I have searched Rust’s Continue Reading

Cassandra Tombstones – DEMYSTIFIED

One thing that Cassandra provides is the “optimized for writes” feature. In Cassandra everything is a write including logical deletion of data which results in tombstones – we can call them special deletion records. Indeed the lack of understanding of tombstones is often the root cause of production issues that people experience with Cassandra. While working on the production cluster we have seen tombstones can Continue Reading

MachineX: The alphabets of Artificial Neural Network – (Part 2)

If you are reading this blog, it is supposed that you have already done with Part 1 No???? Then visit to the previous blog The alphabets of Artificial Neural Network first and comeback here for an awesome knowledge about Neural network working. We got the basic understanding of neural network so let’s get into deep. Let’s understand how neural networks work. Once you got the Continue Reading

Flinkathon: Guide to setting up a Local Flink Custer

In our previous blog post, Flinkathon: First Step towards Flink’s DataStream API, we created our first streaming application using Apache Flink. It was easy, clean, and concise. However, the real power of Apache Flink is seen on a cluster, where data is processed in a distributed manner, with the advantage of multi-core/multi-memory systems. So, in this blog post, we will see how to set up Continue Reading

MachineX: The inevitable Principal Component Analysis

In this blog post, we will look at an interesting feature extraction technique of Machine Learning known as Principal Component Analysis (PCA). PCA is one of the powerful techniques in dimensionality reduction, in fact, the de facto standard for human face recognition. Let’s first understand what is dimensionality reduction Dimensionality Reduction As an example let’s say we have a data set with many-many features(which is Continue Reading
