Fusion OS: Writing an OS in Nim
The author details creating Fusion OS in Nim, emphasizing features like deterministic memory management and capability-based security. The project explores novel concepts and diverges from Unix conventions, focusing on experimentation.
Read original article
The article discusses the author's journey of developing an operating system in Nim, highlighting the language's features such as deterministic memory management, static typing, and inline assembly support. The OS project, named Fusion OS, aims to explore unique concepts like a single address space for processes, capability-based security, computations as state machines, message passing, and a memory-mapped filesystem. The author emphasizes that Fusion OS will not follow a Unix-like structure but will focus on experimental ideas. The source code is available on GitHub. The next steps involve setting up the development environment for the project.
