A tale of an advice gone wrong

This time, it is a story from my college days. By this time, I had owned a PC for about nine months. I had learned a few things from my experiences and failures. I was eager to offer these bits of advice to my classmates, of course, for free. I

Groovy - Intention revealing code with map constructors

"Effective Java" recommends using static factory methods in Java instead of constructors. One reason for this is that static factory methods do a better job at intention revealing than regular constructors. This is because if you have constructors with many arguments, that too multiple arguments with the same

Effective Java with Groovy - Favour Composition to Inheritance

One of the key lessons from the Gang-of-Four Design Patterns is to favour composition over inheritance to achieve better maintainability in our Object-Oriented design. However, most of the codebases written in Java seem to favour inheritance over composition. The main force behind this is the ease of implementing inheritance with

Effective Java with Groovy - Singleton

What is unique about function arguments in JavaScript?

In this post, let us explore that. Let us start with the greet function as follows. function greet(person, message)

Ladder of constructors - pattern or anti-pattern?

The ladder of constructors is a popular pattern one can see in Java applications. In this post, let us try to understand where this pattern becomes necessary and what features the programming languages can provide to come out of the ladder of constructors. Context We want to create a class

Favour empirical evidence over extended arguments

Often, we get into extended arguments when we have to pick an optimal solution from multiple available options. Especially in the case of science and technology, gathering empirical evidence is a highly effective solution. In this post, I share my experience of a code review. This was the first piece

Accepting our shortcomings is a pre-requisite for an improvement

In the initial days of my professional career, I joined a project as a Software Engineer. Once I got access to the codebase, I started going through the codebase. The project was using JSP technology for the views (server-rendered views). A senior developer from the team was demonstrating the implementation

What is in a Jargon?

During my interactions with engineers in various training programs, I noticed a common trend - they often used the term' story point' instead of 'user story' or simply 'story'. These engineers, all graduates from reputed educational institutions and had interned at well-known software development
