ZigでWriting an OS in 1,000 Linesをやる #2023-11-21 自作 OS で学ぶマイクロカーネルの設計と実装(通称エナガ本)の補足資料として公開されているWriting an OS in 1,000 Linesを、できるだけZigでやってみることにした。 目次成果物 #repositoryは以下。 さいしょに #エナガ本は一通り読んでいたのだが、機能に対していくつかのOSの実装を眺める。という構成になっており、個人的には「同じような難易度でRV32を対象に 0->1 でシンプルなOSを作る書籍があるといいなあ」と思いながら読んでいたのだが、まさに欲していたものが公開されたので大喜びで実装を開始した。 自分はそのまま写経してしまうと頭に入らないため、異なる言語で書いてみたり、何らかの制約を課して実施することが多い。今回はZigで書いてみることにした。 概ね問
どうもこんにちは、皆様いかがお過ごしでしょうか。2024年2月、2回目の更新です。最近はオンオフ非常に忙しい日々を送っているという点は変わりないのですが、体調がしっちゃかめっちゃかになりスケジュールを見直したりしていました。降雪に伴い体調がえらいことになりかけていたときに、湊先生やしいたけ先生の言葉がよぎり「休まないと！ そしていろいろな人に一回相談だ！」となれて成長したな……となっていたとかいないとか。 まぁどう見ても「中の人大丈夫？」となる前置きはさておき、今回は現在の作業・デスク環境2024年2月版をお送りできたらと思います。前回のエントリー以来、実はこれまたいろいろとデスク環境が変わったと言いますか、よりスッキリしました。今回も現在使用しているガジェットやアプリなどをご紹介したいと思います。それではいってみましょう。 １、現在のデスク環境 ２、デスク・椅子・照明 ①flexispo
Writing a TrueType font renderer
This post was discussed further on Hacker News. 09 Jan, 2024: There was an issue with newsletter signups. If you tried to sign up, please try again! You should see a success message. Text is the medium of digital interaction, and text rendering has an outsized impact on the overall fit and finish of any system. It therefore pains me that axle has for years relied on a low-resolution 8x8 bitmap fon

Rolling out from Chrome 119 to 123 is a new international CSS feature from CSS Writing Modes Level 4. Vertical writing mode for form control elements means that these elements can be displayed in vertical writing modes. By Chrome 123 the feature will be enabled for all users, this post explains the feature. Vertical writing mode for text-based form control elements Once this feature is fully enabl
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
Streamline non-coding tasks by integrating generative AI into your JetBrains IDEs, browser, and other tools.
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

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

[EN] Writing a Compiler is Surprisingly Easy (part 1)
Part 1: expressions, arithmetic Part 2: statements, control flow Ever since I was a teenager I wanted to create my own systems programming language. Such a programming language would certainly have to be compiled to native code, which meant I'd have to write a compiler. Even though I managed to write several half-working parsers, I'd always fail at the stage of generating assembly code, as the tas

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

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. He
新築アパートに導入した「ライバル物件との差別化設備」とは！？ ｜ hana writing office－不動産専門のライティング事務所
差別化設備①キッチンの天板を人造大理石に アパートに設置されるキッチンの天板はシルバーのステンレスが一般的ですが、今回は白色の人造大理石に変更してみました。 白色の人造大理石に変更して良かったことの一つが、おしゃれな見た目になったこと。 そして、人造大理石は凹凸がないので掃除がしやすく水垢が目立ちにくい特徴があることから、使い心地も良くなります。 もちろんステンレスはさびに強く臭いが付きにくい、人造大理石よりも価格を安く抑えやすいといったメリットはあります。 しかし、今回のライバル物件がステンレスばかりだったことから、差別化として人造大理石を採用しました。 差別化設備②洗面台をフロートタイプ→バックカウンター仕様の三面鏡に バックカウンター仕様の三面鏡 今回新築したアパートがあるエリアは、フロートタイプの洗面台がほとんどでした。 戸建てなどでも使用されているフロートタイプは見た目がおしゃれ

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

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

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’
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
Writing useful terminal TUI on Linux with dialog and jq - Fedora Magazine
Why a Text User Interface? Many use the terminal on a daily basis. A Text User Interface (TUI) is a tool that will minimize user errors and allow you to become more productive with the terminal interface.

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
