My journey with the Agile India conference

Agile India is the longest-running conference I have attended for over a decade. Unfortunately, this year (2025) will be its last edition. I started attending this conference in 2012 as an attendee, and in later editions, I have also been a volunteer and a speaker. The conference had a significant

A search for design patterns that landed me in TDD

During my college days, "Design Patterns" was one of the topics that caught my attention. It wasn't part of our curriculum. The aspect of design patterns that mainly seemed very attractive to me was that by using them, a developer with less experience might be able

Groovy Elvis Operator ?:

In a previous post, I discussed the Nullish coalescing operator in JavaScript. On a related note, I thought of writing about the Elvis operator (?.) of Groovy. A good starting point would be the ternary operator. The ternary operator takes the form of <expression>? <true return expression>

Continuous Delivery vs CI/CD

I have already written about the problems with the tech jargons in general here, and here. This post is on a very particular jargon CI/CD. The software developers' community learned about this excellent practice from the book "Continuous Delivery", authored by Dave Farley and Jez Humble.

One of the travel vloggers I occasionally watch recently started a new venture - an E-commerce service for unique traditional products from rural areas. In one of the videos, he mentioned that his website had crashed on launch day. He claimed the crash was due to the high load. It

Java - Static Factory Methods and Autoboxing

While Java's focus on performance made the primitive types inevitable in the language, its commitment to strong backward compatibility made primitives continue to remain in Java. Thus, the divide between primitive types and reference types (objects) continues to exist. This means conversions between primitive and reference types are

Remembering Comment Ratio

Back in my college days, I had studied the "comment ratio" metric in my Software Engineering class. It was still in use when I joined the industry, though nobody on my team gave it much importance. Comment Ratio is the ratio of the number of lines of comment

Groovy - Simplifying null checks with @NullCheck

While null references have their uses in programming, the creator, Tony Hoare, has admitted that creating null references was a billion-dollar mistake. If you consider the method parameters, most of the time, it would be a good idea to ensure that the parameter value is not null. Otherwise, we will
