Functional Programming: Lambda Calculus

We have already explored the introduction to FP in my previous blog. Once you get into FP, you’ll quickly start hearing the terms lambda and lambda calculus. Lambda: Lambda is basically just a symbol represented as λ that Alonzo Church chose when he first defined the concept of a function. In modern functional programming, lambda means “anonymous function“. Calculus: Calculus is means a formal system in mathematical logic for expressing Continue Reading

HDFS: A Conceptual View

There has been a significant boom in distributed computing over the past few years. Various components communicate with each other over network inspite of being deployed on different physical machines. A distributed file system (DFS) is a file system with data stored on a server. The data is accessed and processed as if it was stored on the local client machine. The DFS makes it convenient to share information Continue Reading

Back2Basics: Algebraic Data Types (ADTs)

To understand ADTs, firstly, we have to understand what is the meaning of the word “algebra“. Algebra Algebra is basically the study of mathematical symbols and the rules for manipulating these symbols. So, logically, an algebra can be thought of as consisting of two things: A set of objects The operations that can be applied to those objects to create new objects Numeric algebra Numeric algebra is the Continue Reading

Dependency Injection: The Core

We can define Dependency Injection as a technique where one object supplies the dependencies to other objects. But what actually does it mean? Well, there are many answers to this question and sometimes they are quite confusing and annoying. But in this blog, I’ll try to keep things quite straightforward and as simple as possible. A class has a dependency on another class if it Continue Reading

Functional Programming: A Paradigm

It’s surprisingly hard to find a consistent definition of functional programming. But I think you can define FP with just two statements: 1. FP is about writing software applications using only pure functions. 2. When writing FP code you only use immutable values. Hence, Functional programming is a way of writing software applications using only pure functions and immutable values. Now, let us understand the Continue Reading
