命名論は各エンジニアの思うスタイルがあると思うので「こうあるべき」というお話はしません。 名前付けに迷うことが多い方の参考になればと思います。 はじめに CX事業本部の中安です。まいどです。 以前に社内でコードレビューをしてもらった際に「プロトコルの命名」についての指摘をいただきました。その時に自分の中で「けっこう曖昧に名前を付けていたなぁ」と反省しました。 では、プロトコルの命名とはどういうものがベターなのか。 今回は「プロトコルの名前の付けかた」に絞って少し調べてみたものを、まとめてみたいと思います。 ドキュメントから読み解いてみる まずは、Appleが公開している「Cocoa向けコーディングガイドライン」を見ていくと Protocols should be named according to how they group behaviors: プロトコルは振る舞いのグループ化の方法

Phantom Types
UPDATE Wed 24th, 2024: This article was originally called “Nominal Types”. A few people on lobste.rs and r/programming pointed out that naming this Nominal Types is incorrect. A better description would be Phantom Types or maybe Tagged Types.

Rails: Active RecordでRepositoryパターンを実装する（翻訳）｜TechRacho by BPS株式会社
概要 元サイトの許諾を得て翻訳・公開いたします。 英語記事: Repository implementation on ActiveRecord | Arkency Blog 原文公開日: 2023/12/28 原著者: Paweł Pacana Repositoryは本質的に、ドメインオブジェクトをその永続化方法から切り離して、それらにアクセスするための限定的なインターフェイスを提供します。Repositoryは戦術的なパターンの一種であり、本記事の導入部で私が説明したい内容よりずっと詳しくMartin FowlerやEric Evansが解説しています。Repositoryパターンが推し進めるものは、いわゆるActive Recordパターンと真逆です。なぜパターンをわざわざ別のものに変換するのでしょうか？ Active Recordパターンは両刃の剣であり、その問題はまさに最大の長所
Stateful recently shared a Node.js announcement about the new test runner module coming to Node.js 18.0.0, which is scheduled for release on April 19, 2022.

This post explains what prefix-only core modules are and what you need to know about them. Be

App structure is complicated. Good app structure improves the developer experience. It can help you isolate what they are working on without needing to keep the entire codebase in your head. A well structured app can help prevent bugs by decoupling components and making it easier to write useful tests. A poorly structured application can do the opposite; it can make testing harder, it can make it

HTML, CSS, JavaScript, Python, PHP, C++, Dart — there are so many programming languages out there and you may even be totally fluent in several of them! But as we aim to write more and better code, the way we write and communicate in everyday language becomes more and more important… and perhaps even overlooked. The way we write about and around code is arguably as important as the code itself. An

Still, there are situations when you want the size of the binary to be as small as possible, and at the same time you do not want to part with Go. The options for how to make the Go binary “lose weight”

JEPでは語れないJava 17
恒例の半年ぶりのblog更新です。 アメリカ西海岸時間の9月14日にJava SE 17がリリースされました。今回のJava 17は多くのディストリビュータがLTSにするバージョンなので、注目度も高いのではないでしょうか。 まぁ、常に新しいバージョンに移行している身にとってみては、LTSはあんまり関係ないんですけどねw また、Oracle JDKが無償で使えるとか、LTSが2年周期になるとかいろいろ話題はあるようですが、ここでは触れないでおきます。 Java 17では17のJEPが導入されました。その中でPreviewがProject Amberによるパターンマッチング、IncubatorがProject Panama関連の2つがあります。 文法ではSealed ClassがPreviewが外されて、正式に導入されました。その他に注目すべきJEPとしてはMacのM1チップ用の移植があります
