関数名、メソッド名、変数名でよく使う英単語のまとめ
プログラミングをしていると関数名、メソッド名、変数名をどうするか悩みます。 ロジックより命名に時間を費やすこともざらにあります。翻訳したり、一般的な命名規則なのかいつも検索して大変です。 よく使うサイトの内容をコピってメモしておく 関数名とメソッド名の違いについて よく使う英単語のまえに、いつもごっちゃにして使っているけど、定義はこんな感じ 「関数」と「メソッド」の違い 似ているところ どちらも何か（引数）を入れると処理をして何か（戻り値）を返してくれます。 違うところ やってること自体は大差ありません。概念としては違います。 メソッドはオブジェクト指向で登場する用語で、オブジェクトの動作を定義したものです。 まずオブジェクトありきなのですね。一方の関数は、オブジェクト云々は関係ありません。 個人的な使い分け Java で登場する関数は「メソッド」です。C 言語で登場する関数は「関数」と呼
This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines? Every programmer today is familiar with function calls (subroutines): F calls G, which stops F and runs G. G does its work, potentially calling and waiting for other functions, and eventually returns. When G returns, G is gone and F continues running. In this pattern, only one fu

成瀬さんは日本最大の Java のカンファレンスでの登壇に加え、 YouTube でも「なるせみ」という IT 技術解説で人気のチャンネルを持ってらっしゃいます。 ドメイン駆動設計とは まずはドメイン駆動設計とは何か紹介いただきました。 ソフトウェア開発は難しい 理由: たくさんの技術 + 対象のドメイン知識 (物流、など) ドメインとはソフトウェア対象領域 ドメインのソフトウェアを作りたいなら、ドメインを主軸とした設計 = ドメイン駆動設計が必要 「エリック・エヴァンスのドメイン駆動設計」(翔泳社刊) という本が原典（翻訳版は 2013 年刊行。 原著は 2003 年出版） ただし、とっっっっっっても難解 ドメイン駆動設計の進め方 “モデリング” と “パターン” というパートに分けて進める 関係者と開発者が集まって、モデリングで設計して、設計したものをパターンで実装する それぞれに専門
Why People are Angry over Go 1.23 Iterators - gingerBill
NOTE: This is based on, but completely rewritten, from a Twitter post: https://x.com/TheGingerBill/status/1802645945642799423 TL;DR It makes Go feel too “functional” rather than being an unabashed imperative language. I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024). From what I can gather, many people seem to dislike the design. I wanted to give m
Introduction to Go 1.19 The latest Go release, version 1.19, arrives five months after Go 1.18. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language There is only one small change to the language, a
It is now 45+ years since C++ was first conceived. As planned, it evolved to meet challenges, but many developers use C++ as if it was still the previous millennium. This is suboptimal from the perspective of ease of expressing ideas, performance, reliability, and maintainability. Here, I present the key concepts on which performant, type safe, and flexible C++ software can be built: resource mana

Type Parameters Proposal
Ian Lance Taylor Robert Griesemer August 20, 2021 StatusThis is the design for adding generic programming using type parameters to the Go language. This design has been proposed and accepted as a future language change. We currently expect that this change will be available in the Go 1.18 release in early 2022. AbstractWe suggest extending the Go language to add optional type parameters to type an
The simplicity of Prolog
Back to homepage Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are all imperative (and for the most part object-oriented) languages,
Range over function types is a new language feature in the Go 1.23 release. This blog post will explain why we are adding this new feature, what exactly it is, and how to use it. Why? Since Go 1.18 we’ve had the ability to write new generic container types in Go. For example, let’s consider this very simple Set type, a generic type implemented on top of a map. // Set holds a set of elements. type

Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked, like a monster whose “aggro” was pulled by a tank. The reason, of course, is due to a few folks taking issue with my outright dismissal of the C and C++ APIs (and not showi
React Best Practices – Tips for Writing Better React Code
By Jean-Marc Möckel Two years ago, I started to learn and use React. And today I'm still using it at my day job as a Software Developer and in my own side projects. During that time I've come across a lot of "typical" issues. So I searched around and found some best practices that I've integrated into my workflow, and I've come up with things that have made my life or my team members' lives easier
Why APL is a language worth knowing
“A language that doesn't affect the way you think about programming, is not worth knowing.”, by Alan J. Perlis.

Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
