Show HN: MesaOS – An operating system written from scratch in Rust (github.com)

MesaOS, a new 64-bit operating system entirely written from scratch in Rust, has been unveiled as a unique experiment in system architecture. Developed by a student known as crackanimador, this original OS features a hybrid kernel designed for security and multitasking efficiency, alongside compatibility with Linux through a shim that allows over 400 Linux driver symbols to operate without modification. Key functionalities include a complete TCP/IP network stack, real-time WAV audio streaming, and a persistent initrd, making it an intriguing framework for testing and development in the operating system landscape. The significance of MesaOS lies in its emphasis on security—leveraging Rust's safety features—while providing a functioning system that developers can experiment with, thereby fostering innovation within the AI/ML community and beyond. It showcases the potential of Rust in OS development and the use of AI-generated code for foundational aspects, enabling users to engage in further enhancements easily. Key technical details include its multitasking model, native syscall support, and extensive device driver capabilities, including audio handling and networking—all packaged to facilitate repeatable, staged development and testing.
