Seiya Nuta's personal blog at seiya.me covers systems and programming. Since 2021, 12 different Hacker News readers have linked it 21 times, most often “Writing a Linux-compatible kernel in Rust”. It is still writing: the last post was on 2026-10-03, and you can follow it by feed.
Too few sampled comments (5) to say how often HN recommends it.?
Why HN links it
HN readers link Seiya Nuta's blog for the post on writing Kerla, a Linux-ABI-compatible monolithic kernel in Rust, and for background on the author's OS work. Comments cite it without judging the writing.

What Hacker News says?
Just to clarify goals of the project: "I completely agree that rewriting existing large, feature-rich, and robust operating system kernels is not a good idea. However, a question came to my mind: what are the pros and cons of writing a practical UNIX-like OS kernel in Rust from scratch? How does it look like? This is why I started this project."[1] [1] https://seiya.me/writing-linux-clone-in-rust

HN discussionA star has been born. A Linux alternative needs to be compatible with Linux binaries and also support modern architectures. If you want Linux to survive, it needs to be re-written from scratch, optimised in Rust and compatible with the existing Linux binaries or drivers. This project might have a chance. From: [0] > TL;DR: I'm writing a Linux clone in Rust just for fun. It does NOT aim to replace the Linux kernel. A…
