Blog OS is a tutorial series and code repository that teaches operating system development in Rust through step-by-step blog posts.
The project addresses the challenge of learning low-level systems programming by providing a structured educational pathway. It breaks down OS kernel development into digestible topics, from building a freestanding Rust binary and minimal kernel through interrupt handling, memory management with paging, and async/await multitasking. Each blog post pairs with a corresponding git branch containing the working code at that stage, allowing learners to see the intermediate state after each lesson and build incrementally.
This resource suits developers who want hands-on experience with bare-metal Rust programming and x86-64 architecture. It works best for those learning kernel concepts rather than building production operating systems, since the goal is educational understanding through guided tutorials. The repository structure—with code organized into separate branches by post number—makes it easy to follow along or jump to specific topics of interest.
The project maintains a substantial user base actively reporting issues and questions. Maintainers respond to new issues and pull requests within a day. Translation work dominates the issue tracker, reflecting ongoing effort to make the material accessible across languages.
