世の中には多くの C# に関する誤解が蔓延っています。 偏見にも満ちています。 そして技術的に正しい批判ではなく、根本的に技術的に誤った批判ばかりで正直悲しい。 技術的に正しい形の批判なら「お、そうだな。そしてそれの解決策はですねぇ...(ﾆﾔﾆﾔ)」となるのですが...。 そして C# 界隈から一歩出ると、「え、C# で作ってるの！？なんで？？」とか言われる事が非常に多い始末。 C# 大好きマンとしては非常に嘆かわしい。 嘆かわしい限りなので、ここでなぜ C# を私が好むか、そして何故ソフトウェアの開発に向いているかを語りたいと思います。そして誤解が解けたら嬉しい。ついでに C# を書きたいと思ってくれたら嬉しい。 想定読者 前書きという名の予防線 事前知識: C# と .NET C# はパフォーマンスの高い言語 C# はビルドも高速 C# はオープンソースかつクロスプラットフォーム 言
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

Dev Containerを使ってステップバイステップで作るPythonアプリケーション開発環境 - 電通総研 テックブログ
みなさんこんにちは、電通総研コーポーレート本部システム推進部の佐藤太一です。 この記事では、VS CodeのDev Containerを使ってOSに依存しないPythonの開発環境を構築する方法をステップバイステップで丁寧に説明します。 VS Codeの利用経験があり、またPythonによるアプリケーション開発に興味のある方を想定読者として記述しています。Pythonの初心者から中級者向けを意識して書いていますので、意図して冗長な説明をしています。 すでにPythonによるアプリケーション開発に十分に詳しい方は、まずはまとめだけ読んでみてください。私自身それほどPythonのエコシステムに詳しいわけではありませんので、知識の抜け漏れは恐らくあるでしょう。そういった事に気が付いたら、XなどのSNSでこの記事のURLを付けてコメントをしていただけると幸いです。 はじめに 事前の準備 最小限のD

Over the past few months, during the lead-up to the TypeScript 5.0 beta, our team spent a good portion of our time looking for ways to improve the performance of our compiler so that your projects build faster. One of the ways we improved was by looking into an oft overlooked aspect of many JavaScript VMs: inline caching. A Brief Primer on Inline Caching Inline caching is an optimization often use

One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m
This all started with a blog post back in 2020, from a tech curiosity: what's the fastest way to scale containers on AWS? Is ECS faster than EKS? What about Fargate? Is there a difference between ECS on Fargate and EKS on Fargate? I had to know this to build better architectures for my clients. In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t

Today we’re excited to announce the release of TypeScript 5.1! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript by adding constructs called types. These types can describe some details about our program, and can be checked by TypeScript before they’re compiled away in order to catch possible typos, logic bugs and more. TypeScript also uses these types to provid

Today we’re excited to announce the availability of TypeScript 4.7! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types.

1 Introduction Compilers, assemblers and similar tools generate all the binary code that processors execute. It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code. Often the only practical way to protect all binaries with a particular security hardening method is to have the compiler do it. And, with software security becoming more and
