About the Book

This is not a traditional programming textbook. Instead of just teaching you syntax, this book helps you understand how computers work, why code is written the way it is, and what you can do with it. It covers C, Python, and RISC-V assembly, along with cybersecurity, system thinking, and the practical side of turning skills into real value. Whether you want to become a programmer, an architect, or an entrepreneur — this book gives you the map.

About the Authors

Lingyuan Studio

Lingyuan Studio is the creative force behind the Caelus OS project — a lightweight operating system built from scratch for educational and experimental purposes. He is also the lead author of this book, a programming enthusiast, and a firm believer that technology education should be accessible to everyone, regardless of age or background. He started writing this book because he saw too many beginners give up after being overwhelmed by thick, jargon-filled textbooks. He wanted to create something different: a book that teaches not just syntax, but the thinking behind it — with a touch of humour and a lot of real-world examples. When he is not writing code or chapters, he is thinking about how to make complex ideas simple enough for anyone to understand. This book is his attempt to do exactly that.
