eBPF（extended Berkley Packet Filter）という用語を著者が初めてみかけたのは、2015年ごろだった。最初は、eBPFをその字面のとおり、パケットキャプチャやパケットフィルタリングを担うだけの、Linuxの新しいサブシステムであろうと認識していた。しかし、実際にはそうではなかった。 システム性能の分析のための方法論をまとめた書籍Systems Performance 1 の著者で有名なBrendan Greggが、Linuxのネットワークサブシステムとは特に関係ない文脈で、古典的なシステム性能計測ツールでは計測できないことを計測するツールを作っていた。その計測ツールがeBPFという技術によって実装されていることを知ったときに、eBPFに興味をもったのだった。また、eBPFは、システム性能を調べる用途以外にXDP（eXpress Data Path）と呼ばれるプ

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog

Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

OBSのブラウザソースで動くものを作るあなたへ
MacOSのみ一部バージョンが異なるのは26.1.1リリースのタイミングでブラウザソースがクラッシュする問題が発生し、hotfixとして26.1.2リリースのタイミングでMac版のみアップデートがなされたためです。 このようにバージョンアップのタイミングはまちまちで、XSplitに関しては最近までChrome 68系、OBSについても最新版の30.xでもChrome 103系と執筆現在(2024/04/22)での最新バージョンであるChrome 124から21バージョン遅れをとっている状況です。 これらのアップデートが進まないことの背景には、OBSがCEF経由でページの表示をテクスチャとして使用するためにテクスチャ共有を利用しながら、ゲームなどの他のソフトウェアやキャプチャを使用するためにもテクスチャ共有を利用していることと、CEFがOffscreen Rendering(OSR)時にハー

The proposal “Pipe operator (|>) for JavaScript” (by J. S. Choi, James DiGioia, Ron Buckton and Tab Atkins) introduces a new operator.

Build strongly typed polymorphic components with React and TypeScript - LogRocket Blog
Real-world examples of polymorphic components There’s a nonzero chance you’ve already used a polymorphic component. Open source component libraries typically implement some sort of polymorphic component. Let’s consider some you may be familiar with: the Chakra UI as prop and MUI component prop.

Gleam is Pragmatic
I’ve spent the past several years working with functional programming languages in my free time – primarily Haskell and OCaml. I love both languages but also find aspects of each frustrating. Haskell is terse and elegant with type classes providing a powerful mechanism for ad-hoc polymorphism. However, it can also be confusingly implicit and I personally find lazy evaluation to have more downsides
`&&` は「かつ」ではない - Qiita
&& はなぜ言語によって「Boolean」を返したり「オペランドの値」を返したりするのか — 歴史的経緯の調査 a && b という式の値は、言語ファミリーによって異なる。 C / Java 系: 真偽値を返す。C では int の 1 か 0、Java では boolean の true か false。 Lisp / Scheme / JavaScript 系(Python、Ruby、Perl も同様): オペランドの値そのものを返す。"foo" && 42 は 42 であり、nil && 42 は nil である。 この違いは偶然ではなく、独立に成立した 2 つの設計系譜が背後にある。一次資料(Lisp 1.5 マニュアル、Dennis Ritchie による C 開発史の論文、MacLisp マニュアル、ECMAScript 初版仕様)を確認した結果を以下にまとめる。調査の過程で分

redbean 2.0 release notes
redbean is a webserver in a zip executable that runs on six operating systems. The basic idea is if you want to build a web app that runs anywhere, then you download the redbean.com file, put your .html and .lua files inside it using the zip command, and then you've got a hermetic app you can deploy and share. I introduced this web server about a year ago on Hacker News, where it became the third

Rust vs C++ Formatting
In Rust, if I want to print some 32-bit unsigned value in hex, with the leading 0x, padded out with zeros, I would write that as: println!("{:#010x}", value); In C++23, if I want to do the same, that’s: std::println("{:#010x}", value); The only difference is the spelling of the name of the thing we’re calling (which is a function template in C++ and a macro in Rust) - otherwise, identical.
