In this post series on Blockchain and related technologies, I am trying to simplify explanation of concepts that are sometimes made very complex by courses and articles across the web.
Let’s start with the basics. What is Blockchain? What is the problem that it tries to solve and why do we need it?
I will use Simon Sinek’s golden circle model (why-how-what) to explain the fundamentals.

In this post, you’ll learn the key steps to create your first Application Load Balancer (ALB) in AWS.
ALB is used to distribute the incoming traffic across multiple targets like EC2 instances — thereby providing single entry point to your applications. It works on Layer 7 (application layer) and provide additional functions like routing, health checks etc. You can read more about ALB in the official AWS documentation.
Here are the key steps to create your first ALB.

In recent times, I spend most of my personal coding time with Smart Contracts. One useful resource on the internet is Road to Web3 course from folks at Alchemy.
You can follow their tutorial here to create your first smart contract and mint an NFT with it.
I am outlining the steps in this post — I suggest you to use this as a guide to using the tutorial from Web3 University.

Off late, I deal with event-driven systems and real-time data at work. It is a completely different paradigm with its own patterns — especially for someone coming from a request/response world.
In this post, I will give you an overview of these systems and value they bring to the table.
If you are delving into data analytics and statistics, it is essential to get a strong hold on hypothesis and related terms.
In this post, I am listing down the key concepts with simple explanations.

I have a love for certifications. I started in 2004 with my first Java certification. As on date, I have about 6 Certifications to my credit.
I was talking about my interest in Certifications to one of my friends and he exclaimed:
I never see a point in certifications! They are a waste of time and money. It is only the experience that counts.
I didn’t disagree with him but tried to put forth a case.
Me: Great! Let’s talk about driving
Him: Sure…
M: There are two drivers to bet on. First one is highly experienced with about 25 years of experience across various categories of vehicles. Second one is relatively inexperienced but fresh out of driving school. Who in your opinion is better?
H: No-brainer. It would be the experienced guy
M: Absolutely, no question about it. But do you think the driving test he did about 25 years ago adds no value?
H: Hmm… can’t say that. It was needed to get a start!
M: Exactly my point with certifications, my friend!
Certifications don’t make you an expert. But they help to get you started from the right base.
Next time you have to choose a candidate — use his certifications as an attribute not as a deciding factor.
