Writing Hypervisor in Zig Ymir, the Type-1 Baremetal Hypervisor Writing Hypervisor in Zig は Zig 言語を使いフルスクラッチで Type-1 Hypervisor を実装しようというブログシリーズです。 OS よりも低いレベルで動作するベアメタル Hypervisor を実装するにあたり、ブートローダ・カーネル・VMM の各コンポーネントをイチから組み立てていきます。 本シリーズでは Ymir という名前の Hypervisor を実装します。 Ymir は Intel 64 (x86-64) CPU で動作し、Intel VT-x によるハードウェア仮想化支援機能を活用します。 Ymir は以下の特徴を持ちます: Type-1 Hypervisor: OS に一切依存しません Linux をブート
I found out about pool allocators some time ago, and I really liked its simplicity and high performance, so I decided to write my own. This article was initially inspired by Dmitry Soshnikov’s article. It’s also worth mentioning that this article was discussed in Hacker News. Similarly to malloc, a pool allocator allows the user to allocate memory at run time. The pool allocator, however, is much

1000行でOSをつくってみる Writing an OS in 1,000 Lines という1000行前後でOSをつくれるコンテンツがあります。 このコンテンツ自体はC言語を前提としているのですが、Rustでもシステムプログラミングが可能なので、今回はRustで挑戦してみました。 Rust で Writing an OS in 1,000 Lines をやってみるときのポイントをまとめておきます。 RISC-V このコンテンツでは RISC-V をターゲットアーキテクチャとしていて、RISC-V のOSを開発します。 RISC-V はオープンソースのRISC (Reduced Instruction Set Computer) のISA (命令セットアーキテクチャ) です。 詳しい説明は、RISC-V で検索すれば数多くヒットします。 この RISC-V 関連で、参考にした主な情報源は
To bootstrap Rust, no cost is too great. Perceptive Rustaceans may have noticed my activity has gone down as of late. There are a handful of different reasons for this. I’ve been the subject of a truly apocalyptic series of life events, including the death of a relative that rattled me to my core. I’ve had more responsibilities at work, leaving me with less time and energy to contribute. Maybe I’v

Autogenerating django integration tests using Kolo and trace inversion Kolo test generation in action I don’t enjoy writing tests I have a confession to make: I don’t enjoy writing tests. I really enjoy writing code, really enjoy bringing a feature to life and getting it out there, but writing tests is probably my least favourite part. I do appreciate the tests that already exist, the ones that ma
Writing a scheduler for Linux in Rust that runs in user-space
Overview I’ve decided to start a series of blog posts to cover some details about scx_rustland, my little Linux scheduler written in Rust that runs in user-space. This project started for fun over the Christmas break, mostly because I wanted to learn more about sched-ext and I also needed some motivation to keep practicing Rust (that I’m still learning). In this series of articles I would like to

【書評】技術ブログの書き方を教えてくれる本を読んでみた -Writing for Developers- - give IT a try
はじめに 洋書ですが、"Writing for Developers"という技術ブログの書き方を教えてくれる本を読んでみました。 www.manning.com 以下は公式ページにあった概要の翻訳です（ChatGPTで翻訳）。 「Writing for Developers」は、優れた技術的洞察を素晴らしいブログや記事に変える手助けをします。著者のピョートル・サルナとシンシア・ダンロップは、エンジニアとプロのライターという異なる視点を組み合わせ、説得力のある作品を書くためのサポートを提供します。この本は一般的な執筆ガイドではなく、技術的なトピック、執筆者、読者に特化して焦点を当てています。 楽しい例やユーモラスなイラスト、たくさんのジョークを通して学べます！この本は、アイデアの生成と優先順位付けから、計画、執筆、改訂の際に考慮すべきこと、成功したブログ投稿をさらなる機会への足がかりとして活
Swift is well-suited for creating user interfaces thanks to the clean syntax, static typing, and special features making code easier to write. Result builders, combined with Swift’s closure expression syntax, can significantly enhance code readability. Adwaita for Swift leverages these Swift features to provide an intuitive interface for developing applications for the GNOME platform. GNOME is a p
Writing secure Go code
What does it mean to keep security in mind when writing Go code? Answering this question in one short article seems impossible. For this reason, we will narrow it down to a few specific practices. They will lead to writing robust, secure and performant code when applied continuously. How do we stay informed about the Go security announcements? How do we keep our Go code patched and up to date? How
I couldn't remember every UUID so I wrote them all down Dec 4, 2024 I’ve been struggling to remember all of the UUIDs 1. There are a lot of them. So this week I wrote them all down. You can see my list at everyuuid.com.
I'm working on an application that needs the ability to schedule tasks. Many applications have a similar need, but requirements can vary greatly. Advanced cases might require persistence and distribution, typically depending on external systems (like a database or queue) to do much of the heavy lifting. My needs are simpler: I don't have a huge variety of tasks or a high number of them. Thread-Per
For the past few days, I have been trying to find a library that would allow me to write programs with a GUI in C++.

Blog Writing for Developers Published Jul 19, 2023 by in DevRel, Blogging at https://rmoff.net/2023/07/19/blog-writing-for-developers/ Writing is one of the most powerful forms of communication, and it’s useful in a multitude of roles and contexts.

Most software tutorials are tragically flawed. Tutorials often forget to mention some key detail, preventing readers from replicating the author’s process. Other times, the author brings in hidden assumptions that don’t match their readers’ expectations. The good news is that it’s easier than you think to write an exceptional software tutorial. You can stand out in a sea of mediocre guides by foll
Pre-RequisitesSystem calls, eBPF, C, basics of low-level programming. IntroductioneBPF (Extended Berkeley Packet Filter) is a technology that allows users to run custom programs within the kernel.

I needed a bit of a break from “real work” recently, so I started a new programming project that was low-stakes and purely recreational. On April 21st, I set out to see how much of a Unix-like operating system for x86_64 targets that I could put together in about a month. The result is Bunnix. Not including days I didn’t work on Bunnix for one reason or another, I spent 27 days on this project. Yo

Writing a C Compiler
Compilers are at the heart of everything programmers do, yet even experienced developers find them intimidating. For those eager to truly grasp how compilers work, Writing a C Compiler dispels the mystery. This book guides you through a fun and engaging project where you’ll learn what it takes to compile a real-world programming language to actual assembly code. Writing a C Compiler will take you
Working with large datasets in Node.js applications can be a double-edged sword. The ability to handle massive amounts of data is extremely handy, but can also lead to performance bottlenecks and memory exhaustion. Traditionally, developers tackled this challenge by reading the entire dataset into memory at once. This approach, while intuitive for smaller datasets, becomes inefficient and resource

How you create the job description also plays a major role. This is not something to be taken lightly. The scarcity of workers can an
Last month the V8 team published an excellent blog post on what they call the V8 Sandbox. This isn’t a sandbox for your JavaScript code — it’s intended to mitigate browser exploits caused by bugs in the JIT compiler itself. That’s important work because they report that most Chrome exploits start with a V8 memory safety bug. V8 is written in C++, so it may seem like these are the sort of bugs you’
Bliss - A constructed writing system for fast and beautiful writing
As a long-time fan of constructed scripts, I have always tried to find a way to create my own writing system without reinventing the wheel. Unfortunately, for my purposes at least, there are simply too many writing systems (or conscripts) to invent something new and useful at the same time. Learning from the bestsFor a while I had Utopean as my favorite conscript. In case you didn't know, and as a
How to think in writing
The reason I've spent so long establishing this rather obvious point [that writing helps you refine your thinking] is that it leads to another that many people will find shocking. If writing down your ideas always makes them more precise and more complete, then no one who hasn't written about a topic has fully formed ideas about it. And someone who never writes has no fully formed ideas about anyt
How To Improve Your Microcopy: UX Writing Tips For Non-UX Writers — Smashing Magazine
Not all companies can afford to hire a full-time UX writer (or are mature enough to consider it yet). As a result, UX writing is often outsourced to team members who may not have sufficient expertise in working with text, such as UX designers and product managers, or to the content or marketing team, who may lack expertise in UX. Meanwhile, interface copy plays a crucial role in the overall user e
