I’m learning systems programming in Rust, and I’m doing it in public because, as I’ve put it, “Building in the open keeps me honest.” That is the motivation I can state plainly. The rest is a learning project: getting closer to the parts of software that explain how programs interact with the machine and the operating system.
What I mean by systems programming
Systems programming is a broad label, not one tidy subject with a single syllabus. It can lead toward operating systems, networking, databases, or the mechanics of programming languages and runtimes. Those areas overlap, but each asks different questions. An operating-systems learner might want to understand processes and system calls; someone drawn to networking may want to investigate how programs communicate; a database project raises its own questions about storage and data handling.

That breadth is part of the appeal, and also a reason not to treat “learn systems programming” as one enormous task. A useful starting point is a concrete interest or question. The advice to choose a focus comes from participants in a June 2021 systems-programming discussion, not from a universally validated curriculum.

Learning in public gives the work an audience and a record. My stated reason is simple: “Building in the open keeps me honest.” It does not mean I have a complete roadmap or a polished explanation for every step. It means making the learning visible rather than presenting only a finished result.
#1 Best Overall
My current focus is systems programming in Rust. That is a description of what I’m learning, not a claim that Rust is the right first language for everyone. A learner’s best route depends on the question they want to answer and the kind of structure that helps them keep going.
How to begin without trying to learn everything
Pick a question with a boundary
Choose a subject area—such as operating systems, networking, or databases—and turn it into a question small enough to investigate. A focused question makes it easier to decide what to build, what to read, and which unfamiliar details matter now.
Rank #2
Use a small experiment to make an idea concrete
Practical experiments can make systems concepts less abstract. Julia Evans’s indexed writing emphasizes incremental learning and small milestones, with examples such as using strace to observe a program’s interactions with the operating system. Treat an experiment as a way to investigate one behavior, not as proof that you understand the whole system.

One participant in the June 2021 discussion recommends starting with a problem or project before trying to understand a large open-source repository. A small program that exercises a system interface can give you a concrete reason to inspect existing code later. That sequence is one learner’s advice, but it offers a practical alternative to reading a large codebase without a specific question in mind.
Rank #3
Choose structure that fits the topic
If operating systems are your focus, Operating Systems: Three Easy Pieces was recommended in that discussion as an introductory resource. It is one option, not a required purchase; the recommendation does not establish current edition, price, or availability. A textbook or course can provide structure, while a self-directed project offers a more immediate way to test ideas. Neither route is established as best for every learner.

A useful public record need not imply expertise. It can make the subject, questions, and small milestones visible while leaving room for uncertainty. The available portfolio excerpt identifies this as a public-learning piece and names Rust as a current learning focus; it does not provide enough of the article text to establish additional personal reasons, projects, milestones, or conclusions. I won’t claim those details on its behalf.
For readers asking how to learn “proper systems programming,” the practical takeaway is to give the broad subject a specific shape: choose an area, find a question, try an experiment or small project, and use reading to answer what that work brings into focus. That is a set of possible approaches, not a proven sequence. The point of learning in public is to let the work—and its limits—remain visible as it develops.
