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
TL;DR; We are changing std::sort in LLVM’s libcxx. That’s a long story of what it took us to get there and all possible consequences, bugs you might encounter with examples from open source. We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can

PySkyWiFi: completely free, unbelievably stupid wi-fi on long-haul flights | Robert Heaton
The plane reached 10,000ft. I took out my laptop, planning to peruse the internet and maybe do a little work if I got really desperate. I connected to the in-flight wi-fi and opened my browser. The network login page demanded credit card details. I fumbled for my card, which I eventually discovered had hidden itself inside my passport. As I searched I noticed that the login page was encouraging me
Reading the excellent article by JeanHeyd Meneide on how broken string encoding in C/C++ is made me realise that Unicode is a topic that is often overlooked by a large number of developers. In my experience, there’s a lot of confusion and wrong expectations on what Unicode is, and what best practices to follow when dealing with strings that may contain characters outside of the ASCII range. This a
XOR
The truth table of XOR, shown in two different ways But just saying what it is doesn’t give a good intuition for what things it’s useful for, or when to use it. So in the next few sections I’ll present a few different ways of thinking about what XOR does. For such a simple operation, it’s possible to describe what it does in a lot of quite different-looking ways. But all of them are true at once!
Photo by Chris Ried / Unsplash I'm sure many programmers, particularly web developers have heard of the RSA cryptography system. RSA is an asymmetric cryptography system, meaning that one key is used for encryption and the other for decryption. I've seen a lot of articles explaining the general principles of asymmetric cryptography, but I have not seen any that give easy-to-understand explanations
Large Text Compression Benchmark Matt Mahoney Last update: July 3, 2025. history This competition ranks lossless data compression programs by the compressed size (including the size of the decompression program) of the first 109 bytes of the XML text dump of the English version of Wikipedia on Mar. 3, 2006. About the test data. The goal of this benchmark is not to find the best overall compressi
Introduction: These Aren’t the JSONs You’re Looking For JSON (JavaScript Object Notation) was designed as a simple, lightweight, and human-readable data interchange format, often positioned as a more accessible alternative to XML. It has become the de facto standard for web APIs and system integration. However, while the specification itself is straightforward, different programming languages and
Amazon Inspectorの検出結果をリソース単位でまとめてメール通知する方法 | DevelopersIO
はじめに 以前、Amazon Inspectorの検出結果をAWS Security Hubを経由してメール通知する方法をご紹介しました。 Inspectorは脆弱性を検出するたびに結果を作成するため、1つのリソースに対して複数の脆弱性が見つかった場合、その数だけメール通知が発生してしまいます。例えば、100個の脆弱性が検出されると、100通のメールが送信される状況でした。 本記事では、脆弱性ごとの通知ではなく、1リソースごとに検出結果をまとめて1回の通知で済ませる方法をご紹介します。 構成は以下のとおりです。 本実装は、以下の流れで処理を行います。 Inspectorで検出結果が作成され、Security Hub経由でEventBridgeが起動します。 Firehose ストリームに検出結果が一時保存されます。 Firehose ストリームは、指定したバッファ期間内に受信したイベントを
A History of Clojure
71 A History of Clojure RICH HICKEY, Cognitect, Inc., USA Shepherd: Mira Mezini, Technische Universität Darmstadt, Germany Clojure was designed to be a general-purpose, practical functional language, suitable for use by professionals wherever its host language, e.g., Java, would be. Initially designed in 2005 and released in 2007, Clojure is a dialect of Lisp, but is not a direct descendant of any

Java Interview Questions
Java remains one of the most common and popular programming languages in the world because of its strong features. Therefore, it’s no surprise that good Java programmers are very much sought after by almost all organizations across the world – be it startups or large multinational corporations. Considering the above, we created a list of common job interview questions about Java programming with d
