If you’ve ever peeked inside a machine learning model—or even trained one—you’ve probably heard the phrase “gradient descent.” But what is it exactly? And why should engineers care? Today, let’s strip away the jargon and look at gradient descent in plain English. No equations, just clear thinking — and a link to the world of […]

Why Every Engineer Should Understand the Basics of Machine Learning
Whether you’re building back-end systems, mobile apps, or front-end features, one thing is becoming clear: machine learning (ML) is no longer just for data scientists—it’s becoming part of a modern engineer’s toolbox. But why should every engineer care? 1. Models Are Just Supercharged If-Else Statements Imagine you’re writing code to categorise emails as “spam” or […]
Why You Need Custom Exception Classes
Custom exception classes are an essential part of robust and maintainable software development. Here are several key reasons why you might need to define your own exception classes in Python: 1. Clarity and Specificity Custom exceptions can make your code more readable and easier to understand. By defining exceptions that are specific to your application, […]
User-Defined Exceptions in Python
Introduction In Python, exceptions are events that disrupt the normal flow of a program. When such an event occurs, the program crashes unless the exception is handled. Python has many built-in exceptions, such as ValueError, TypeError, and IndexError. However, there are situations where these built-in exceptions may not adequately represent the specific error conditions of […]
Understanding Python Decorators
Python decorators are a powerful tool that allows you to modify the behavior of a function or class method. Here’s a step-by-step guide to understanding them with examples. Step 1: Understand Functions as First-Class Objects In Python, functions are first-class objects, meaning they can be passed around and used as arguments, just like any other […]

Introduction to JSON
What is JSON? JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language but is language-independent, meaning it can be used with many programming languages. Why Use JSON? […]
Understanding File Path Systems in macOS and Windows: Differences and Characteristic
The file path system is a method used by operating systems to specify the location of a file or directory in the filesystem. Both macOS and Windows have their own conventions for representing file paths, reflecting differences in their underlying file system structures and user interface designs. Here’s a breakdown of the file path systems […]
