A quick method to learn an uber cool way of communication

The movies Parasite by Bong Joon Ho, Interstellar by Christopher Nolan, Tin Tin by Steven Spielberg, Independence Day by Rolan Emmerich all have something in common.

No, I’m not talking about their success in the box office, nor their super popular directors. I’m talking about the usage of Morse code in all these movies. It played a huge part in the communication that happened in some of the most crucial moments in their story.

Even though 200 years have passed since its invention, it’s still referred to and used…


Make this a habit and see your happiness levels multiply

A couple of years back, I came across the concept of the Gratitude jar from a post by Elizabeth Gilbert, the famous author of Eat Pray Love, Big Magic and a few more fantastic novels.

Exploring Checkov

In part 1 of this series, we looked into how we can use Terratest for testing our Infrastructure as a code setup.

From their docs[1]:

Checkov is a static code analysis tool for infrastructure-as-code.

It scans cloud infrastructure provisioned using Terraform, Terraform plan, Cloudformation, Kubernetes, Dockerfile, Serverless or ARM Templates and detects security…


Exploring Terratest for Terraform

But before we jump, let’s start with a quick introduction on the need for a testing tool/framework for Terraform with a quick blast from the past on how it all started.

Do you remember the time when cloud became a buzzword everywhere and companies started experimenting with it? It felt like we were entering a new era where everything became elastic. We could launch the servers with a small touch of our finger on the mouse and voila, like magic, all the resources we wanted got created. …
