I'm 17 and heading into my final year of high school. I've been interested in computer science for a long time, and over the past year I've become especially curious about operating systems, how hardware and software interact, how the Linux kernel works, and the open-source development process. I'd eventually like to contribute to the Linux kernel, possibly as a career, so I decided to learn C using Beej's Guide. The material is understandable, but I'm struggling with the practical side of learning: I don't know what programs to create after learning a concept, and I need some kind of structured workflow to avoid getting stuck or frustrated. Since I'm still a complete beginner in C, what are some good ways to practice the language and build useful skills without relying on AI?

The best practice is to build small things, even if they aren’t directly related to the Linux kernel yet. Projects driven by your own curiosity are useful because they force you to apply concepts, debug mistakes, and gradually combine features. Start with simple programs such as a calculator, text-based game, file reader, command-line utility, or a small version of a familiar tool. Don’t worry about writing kernel code immediately—get comfortable with C fundamentals first. As you become more confident, you can study how operating-system components work, explore hardware projects with something like an ESP32, or eventually experiment with writing a simple driver. Kernel contribution is a long-term goal, so there’s no need to rush into it as a complete beginner.
That makes sense. I’m still at the stage where I need beginner-level C projects, and contributing to the kernel is more of a future goal than something I expect to do right away.
