Reading Time: 4 minutes Whenever we have tried to learn about functional programming, these two terms have always gained our attention. The first one is pure functions and the second one is immutability. I have tried to explain what are pure functions in one of my previous blogs. In this particular blog, we’ll discuss the practicality of programming with immutability. What does immutability mean? The definition that you can Continue Reading
Reading Time: 3 minutes HashiCorp Vault is a secret management tool which provides a secure and reliable way to store secrets like passwords, access token, secret API key etc.
There are applications that need to interact with third party services and for that it needs various credentials. There are scenarios in which we need different credentials to process different requests. So, where will you store them? Can you really hard-code them and publish them to your sub-versioning tool? Ofcourse not. This is not a recommendable approach.
Reading Time: 3 minutes What is RabbitMQ and Why we should use it? We often get this question in our mind when we look to any project and see RabbitMQ in its technical stack. So, this blog will give you a brief introduction to RabbitMQ. RabbitMQ is a message-broker whose basic functionality is to accept and forward the message. It is an open-source enterprise messaging system modeled on the Advanced Continue Reading
Reading Time: 2 minutes 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
Reading Time: 4 minutes One of the challenges faced by distributed systems is how to keep the replicas consistent with each other. Maintaining consistency requires balancing availability and partitioning. Fortunately, Apache Cassandra lets us tune this balancing according to our needs. In this blog, we are going to see how we can tune consistency levels during reads and writes to achieve faster reads and writes. Before digging more about Continue Reading
Reading Time: 2 minutes Logistic Regression, a predictive analysis, is mostly used with binary variables for classification and can be extended to use with multiple classes as results also. We have already studied the algorithm in deep with this blog. Today we will be using KSAI library to build our logistic regression model. Setup
Reading Time: 2 minutes Hi Everyone! In our previous blogs, we have discussed Decorator design pattern and Adapter design pattern. Now, its time to discuss another Structural design pattern i.e. the Proxy design pattern. We will implement the same EUGDPR problem using the Proxy design pattern, which we implemented using the Adapter design pattern in our previous blog. Problem Statement: Earlier, in many applications, all the user-specific details like Continue Reading
Reading Time: 3 minutes In the previous series of blogs, we have seen how we can do error handling in Scala. In this blog, we will explore yet another way of handling exceptions using the functional style of programming. Scalactic is a library which provides an “Either with attitude” named Or, designed for functional error handling. Or gives you more convenient chaining of map and flatMap calls (and for Continue Reading
Reading Time: 2 minutes I hope you have already been through the following blogs in order to learn control flow and iteration in RUST: RUST: Quick Start & Exploring Cargo RUST: Begin the Journey with CODE Basically, RUST is no different compared to other programming languages in the context of loops and iteration, if you have already worked with any language like C, C++, Java, Scala, etc. then it Continue Reading
