1000行でOSを作ってみよう 本書では、小さなOSをゼロから少しずつ作っていきます。 OSと聞くと腰が引けるかもしれませんが、OS (特にカーネル) の基本機能は案外単純です。巨大なオープンソースソフトウェアとしてよく挙げられるLinuxでさえ、バージョン0.01はたった8413行でした。様々な要求に応えるために次第に肥大化していっただけで、当初は大変素朴な実装になっていました。 本書ではコンテキストスイッチ、ページング、ユーザーモード、コマンドラインシェル、ディスクデバイスドライバ、ファイルの読み書きをC言語で実装します。これだけ様々な機能が詰め込まれているのに、コードは合計でたった1000行未満です。 「1000行なら1日でできそう」と思うかもしれませんが、初学者には少なくとも3日はかかるでしょう。OS自作のハマりポイントは「デバッグ」です。アプリケーション開発とは違うデバッグ手法

Infinite Mac
Infinite Mac is a project by Mihai Parparita to make classic Mac and NeXT emulation easily accessible. It uses WebAssembly ports of Mini vMac, Basilisk II, SheepShaver, DingusPPC, PearPC, and Previous to allow a broad set of OS versions to run on the web. Shortcuts to the most popular versions are available: system6.app, system7.app, kanjitalk7.app, macos8.app, and macos9.app. FAQ How do I use it?
& how to analyze design choices without jumping to conclusions Over the years, I have had many encounters with Japanese websites — be it researching visa requirements, planning trips, or simply ordering something online. And it took me a loooong while to get used to the walls of text, lavish use of bright colors & 10+ different fonts that sites like this one throw in your face: Hankoya — a website

This site contains an original, self-contained guide to learning the fundamentals of Modern C++, intended to be the basis of a self-study course. Some Chapters depend upon material presented in earlier ones, so studying them linearly is recommended. There are also regular posts (accessible from the front page) which cover topics or areas of C++ not covered in the course. If you have any queries or

WebSockets vs Server-Sent-Events vs Long-Polling vs WebRTC vs WebTransport For modern real-time web applications, the ability to send events from the server to the client is indispensable. This necessity has led to the development of several methods over the years, each with its own set of advantages and drawbacks. Initially, long-polling was the only option available. It was then succeeded by Web

Downfall attacks target a critical weakness found in billions of modern processors used in personal and cloud computers. This vulnerability, identified as CVE-2022-40982, enables a user to access and steal data from other users who share the same computer. For instance, a malicious app obtained from an app store could use the Downfall attack to steal sensitive information like passwords, encryptio

A few years ago most API designers, developers, and technical writers would have had very little reason to bump into JSONPath, but its starting to get more and more relevant as more tools and standards start relying on it. So what is JSONPath, what is it used for, and how can you get up to speed with using it? JSONPath is a query language that can be used to extract data from JSON documents, which

Linux Crisis Tools
(This is based on Table 4.1 "Linux Crisis Tools" in SysPerf 2.) Some longer notes: [1] bcc and bpftrace have many overlapping tools: the bcc ones are more capable (e.g., CLI options), and the bpftrace ones can be edited on the fly. But that's not to say that one is better or faster than the other: They emit the same BPF bytecode and are equally fast once running. Also note that bcc is evolving and
