I've been learning Rust for some time now and feel confident about the syntax, ownership, borrowing, and the various features of the language. I can read Rust code and understand small examples without issues. However, when I try to work on actual projects, I often find myself stuck. It's not a matter of not understanding the syntax; rather, I struggle with figuring out the necessary steps to bring my ideas to life.
For instance, I'd like to create projects such as a CPU scheduler, a compiler component, a binary analysis tool, or a system utility that communicates with the operating system. Yet, as I begin, I realize I have gaps in my understanding of how software interacts with the OS, how programs connect with hardware, the architecture of such applications, and what components I need before diving into coding. Most resources seem to focus on isolated examples rather than showing the complete journey from idea to functioning program, leaving me with bits of knowledge but no cohesive picture.
Has anyone else experienced this when learning systems programming or Rust? How did you manage to go from grasping the language to actually knowing how to design and execute real systems?

Starting with simple projects helps too. Focus on a specific idea, like making a basic HTTPS server from scratch using syscalls. Don’t overload yourself with complexity right away—practice will make the process clearer! Also, don’t forget to utilize online resources and guides; there's an overwhelming amount of information out there that you can leverage when you feel stuck!
Getting stuck is part of the journey for every programmer, no matter how experienced. Just tackle one problem at a time! If you don't know something, take some time to research it rather than trying to figure everything out at once. Working through these obstacles is a crucial skill—it's how you'll learn to build effective solutions over time. And remember, the Internet is full of tutorials for just about everything!
It's definitely a challenging path! Building systems software requires a good grasp of computer architecture. I recommend picking up some books on the topic—it'll help you understand how machine code interacts with CPU instructions. The concepts will start clicking once you get a handle on the theoretical background.
When I started writing OS-related code, I also felt lost at first. Learning to interact with hardware often required me to dive into inline assembly, especially when fetching values from specific registers. I found resources like osdev incredibly helpful to understand how to access information from registers and what operations were needed. It's definitely a journey, but spending time on the fundamentals can really help you get started!
A great way to tackle projects is to break them into smaller pieces. For example, if you're creating a simple game like "guess my number", you can list out the steps: generate a random number, prompt the user, read input, etc. Tackle each part individually; it's all about iterating and refining your code over time. Don't stress about making it perfect on the first try—programming is a process!
