Operating System in 1,000 Lines – Intro (operating-system-in-1000-lines.vercel.app)

Article summary

The article introduces a book that guides readers in building a small operating system from scratch in 1,000 lines of code. The book covers basic functions such as context switching, paging, and user mode, and is written in C. The author notes that debugging is a challenging part of creating an OS, but provides examples and resources to help readers learn. The book is available under the CC BY 4.0 license and the implementation examples are under the MIT license.

Main themes

• Operating System Development
• RISC-V Architecture
• Low-Level Programming
• Debugging Techniques
• Alternative Programming Languages

What commenters say

• Some commenters appreciate the tutorial and plan to use it as inspiration for their own projects, including rewriting it in Rust.
• Others suggest that the OS could run on real hardware, such as the Raspberry Pi or Raspberry Pico, with some modifications.
• A few commenters point out typos and errors in the book and suggest corrections, while others appreciate the effort to create an educational resource.
• There is a discussion about the use of C as the programming language, with some arguing that it is outdated and others defending its use for low-level programming.
• Some commenters mention alternative operating systems and programming languages, such as Ada and Rust, and suggest that they could be used for similar projects.
• A few commenters express concern that the project may not be suitable for production use due to performance issues and lack of JIT compilation.
• Others suggest that the project is a good learning experience and that it can help to move the state of the art forward in operating system design.
• There is a debate about the value of creating another Unix-like kernel in C, with some arguing that it is unnecessary and others seeing it as a valuable learning experience.
