Have you ever wondered how Python makes objects work with operators like + or -? Or how it knows how to display objects when you print them? The answer lies in Python’s magic methods, also known as dunder (double under) methods. Magic methods are special methods that let you define how your objects behave in […]

In this digital world, companies rely on the latest technology to run their businesses, and the risk of cyber attacks is high. Every product, whether it’s software or an application, should go through some sort of security testing process. These checks reveal whether the product is safe or vulnerable to threats. Penetration testing is a […]
Prompt engineering isn’t just a skill these days – it gives you an important competitive edge in your development. In 2025, the difference between AI agents that work and those that don’t comes down to how well they’re prompted. Whether you’re a developer, product manager, or just building with AI, getting really good at prompt […]
Whether you’re building a web app, mobile app, or API, understanding how to implement robust authentication and authorization is a critical skill. AWS Cognito is a powerful ability that simplifies user management, authentication, and access control, making it an essential technology for developers and businesses alike. By mastering AWS Cognito, you can build secure, scalable […]
If you’ve followed cybersecurity news over the past few years, you’ve likely come across EternalBlue. This critical Windows exploit played a key role in the widespread WannaCry ransomware attack that affected systems in over 150 countries. In this article, we’ll walk through how EternalBlue works, how to scan for it, and how to exploit it […]
Edge computing is a distributed system design that moves computation and data storage to where it’s most required – at the ‘edge’ of the network. Moving these tasks to the edge of the network enables computing in real time, which reduces the cost of bandwidth and latency significantly. But edge computing environments face various problems, […]
JavaScript is the backbone of modern web development, powering everything from interactive websites to complex web applications. Object-oriented programming (OOP), prototypical inheritance, ES6 classes, Node.js, and asynchronous programming are all key areas that can take your JavaScript skills to the next level. We just published a course on the freeCodeCamp.org YouTube channel that will teach […]
Whenever I publish a new article, I receive countless emails and DMs across social media asking, “How can I become a Full Stack Developer like you? How much DSA do I need to know? How long does it take?” Well, I always say, “Wait for my next tutorial!”—and here it is! This guide will walk […]
In this tutorial, we’ll build a simplified, AI-flavored SIEM log analysis system using Python. Our focus will be on log analysis and anomaly detection. We’ll walk through ingesting logs, detecting anomalies with a lightweight machine learning model, and even touch on how the system could respond automatically. This hands-on proof-of-concept will illustrate how AI can […]
Deep learning has revolutionized the way we approach complex problems like image recognition, natural language processing, and even audio analysis. At the core of many deep learning applications is PyTorch, a powerful and flexible framework that allows developers and researchers to build and train neural networks efficiently. If you’re looking to gain hands-on experience with […]
