This blog is just a very short personal summary of the book Kubernetes in Action. Feel free to skip it if you have read that book
First there were monoliths deployed as a big components and then world moved to microservices (ms). As the companies grew, the number of ms built and deployed were enormous and managing the life cycle of these ms needed a special role and skillset to manage infrastructure. Thats where devops role came in to manage the infra/hardware failure/migration of failure components to healthy ones and so forth. MS deployment was solved with dockerized containers but…

So there are number of tutorials available for monitoring and alerting using Prometheus and this is another one. The reason I had to write this was the time it took me to setup and configure it locally. The resources are numerous but I couldn’t find a single step by step code tut that could share a practical code approach.
This tutorial will take you on an experiment using prometheus with Java Spring Boot framework.
THIS IS NOT A INFRA SETUP OR DEEP-DIVE TUT FOR PROMETHEUS. …

I really believe in the philosophy that what you can’t create, you can’t understand clearly. While going through Machine learning algorithms, I came across Naive Bayes classifier. It made me curious to understand the logic behind the famous formula everyone was using and how it came into existence. This article tries to share my learning experience from scratch and in simple words. I am sure there are many curious minds out there and this article will surely help them.
Descriptive analysis or statistics means the summary of a dataset showing the central tendency and the spread of the data using things like mean, median, standard deviation etc
I remember studying these concepts when I was in school but I never understood the use in real life until recently.
I was recently playing with some salary data to learn machine learning. I created some normally distributed data. In the end I appended two huge salaries to play around with different statistics concept.
I uploaded the data in Google sheets and to my surprise, it had an Explore feature which had…
Any claim which is not backed by data is difficult to digest. Be it any vertical or industry, it’s easy to convince yourself, your stakeholders and your team mates if your arguments are backed by data.

There have been countless times when as an Engineering head, I was put in a situation to decide between one or the other things. And working in a dynamic industry there is a highly likely chance that a choice what seem to be best few years back might have been replaced by a new choice.
I have been observing that the young blood these days are more interested in using a technology or framework instead of understanding how does a particular technology or framework works behind the scene? OR even stepping back to understand why was this framework built at the very first place?
As an engineering manager, I have personally seen in teams that everyone is comfortable in using a framework like Spring Framework or Spring Boot but none took an interest in asking questions like:
TL;DR: The article talks about customising the UPI apps chooser on your android device via webpage/hybrid app running in a webview.
Unified Payment Interface (UPI) is gaining traction in financial domain following which developers and companies are finding ways to explore its use-cases over web. Since UPI requires to validate your mobile number, so it only works on your mobile OS and not on webpage/HTML/JS (android, iOS etc).
Companies wanting to integrate UPI in their web pages accessible via hybrid apps/ mobile webviews still can’t build user experiences around UPI because they…
In this experiment, I talk about how Augmented Reality with JS can be used to make learning more fun and interactive. The case study will discuss the design process, implementation and feedback from children in the age group 2 to 10 years.
Augmented Reality (AR) has always attracted me, and in this experiment, I try to create a practical AR application. The use-case we will cover is primary education and we will see how we can make the learning fun and interactive. We will make an app to learn alphabets in three languages primarily: Punjabi, Hindi, and English.
We believe that there is a difference between the way developers look at things VS the way a non dev looks at things.

A week ago I started feeling pain in my upper right side of abdomen whenever I ate something. It was so bad that I had to get admitted in the emergency and was treated for hyperacidity and gastritis. The sensation came back again after two days with a less severity now. Went for an ultrasound and was shocked to find 10.2 mm stone stuck in the neck region of gallbladder + grade 2 fatty liver. …
