Sharing notes from my ongoing learning journey — what I build, break and understand along the way.
What Is Reinforcement Learning? A Beginner-Friendly Explanation with Examples In some machine learning problems, we don’t have the correct answer in advance, nor even labeled data. Instead, the model must learn from experience by trying, observing outcomes, and improving over…
Unsupervised Learning: How Machines Learn Without Labels In this section, I want to explore how we can build models even when we have no labeled data at all. This brings us to unsupervised learning—a set of techniques used when there’s…
Supervised Learning Explained: Regression and Classification for Beginners I’m currently taking a machine learning course on Coursera, and one of the first major topics covered is Supervised Learning. To solidify what I’ve learned and also share helpful content on my…
Inside the CPU: The 4 Steps of the Instruction Cycle As I continue learning how computers work at their core, one fundamental concept I’ve come across is the Instruction Cycle, also known as the Fetch–Decode–Execute–Store (FDES) cycle. This cycle is…
How Computer Memory Works — From CPU Registers to Disk Swap Since I’ve started learning how computers actually work under the hood, one of the topics that completely changed how I see system performance is something called the Memory Hierarchy.…
How Computers Understand 1s and 0s: Binary System, Character Encoding, and Logical Operations We’ve all heard that computers work with 1s and 0s, but what does that actually mean? What do those 1s and 0s represent? How do letters turn…
Everything I need to learn, understand, and master to become a Cybersecurity Expert Why I Built This Roadmap Over the past few months, I’ve been diving deep into the world of cybersecurity and quickly realized how massive and layered this…
How I Discovered the Hidden Power of System Logs While researching security-related topics, I kept coming across the term “logs.” I didn’t quite understand what made them so important at first. I thought logs were just boring text files the…
My First FastAPI Project Today, I built my first working web project using FastAPI. I’m sharing the whole process step-by-step — what I did, what issues I encountered, and how I learned. First, I Installed Visual Studio Code While installing…
What Is OAuth 2.0? A Deep Dive into the Authorization Protocol Not long ago, I tried to implement Google OAuth login in one of my own web projects.Although I haven’t fully succeeded yet, the process pushed me to deeply understand…
