[社内勉強会レポート]『The Rust Programming Language』勉強会#1 | DevelopersIO
Rustの入門書『The Rust Programming Language』の社内勉強会レポートです。 はじめに 社内で行われた勉強会のレポートです。参加者のRustの経験は実務で少しずつ導入している人からRustの本を買って積んだままにしている人まで様々です。 クラスメソッドのSlackには様々なチャンネルがあり、その一つRustについて話す所があります。そこで社内勉強会を行うことになったのでそのレポートを記事にします。 Developers.IOでは社内勉強会についての記事は過去にテスト駆動開発の読書勉強会などのレポートなどが公開されています。この勉強会のレポートもそれを踏襲します。 [社内勉強会レポート] 『テスト駆動開発』読書勉強会 #1 ｜ DevelopersIO TRPLについて 今回勉強会のテーマになっている『TRPL』はRustが公式に提供している入門書です。The R

JavaScript ES6のAsync/Awaitで非同期処理とエラー処理、並列処理を解説！初心者向け完全ガイド - deve.K's Programming Primer - プログラミング初心者のための入門ブログ
この記事では、ES6のasync/await、およびPromises.all()を使用して非同期プログラミングを容易にする方法を学習します。 前回でのPromiseチュートリアルは以下で学ぶことができますので参照ください。 dev-k.hatenablog.com async/awaitとは asyncキーワード awaitキーワード Promise並列処理 async/awaitでのループ エラー処理 async/awaitでFetchを使用する方法 使用に関する注意点(ルール) 最後に async/awaitとは async/awaitは技術的に言えば、Promisesのシンタックスシュガー(Syntax sugar)となります。 シンタックスシュガーとは簡単に言ってしまえば、構文を省略しプログラムを書いていく事をシンタックスシュガーと言います。 ですが、これはプログラミング言語によっ
JavaScriptの巻き上げとは？変数と関数での動作 - deve.K's Programming Primer - プログラミング初心者のための入門ブログ
本日はJavaScriptの巻き上げについて学習します。 巻き上げとは？ 変数の可変巻き上げ 関数の巻き上げ 関数式(無名関数)の巻き上げ クラスでの巻き上げ まとめ JSのスコープについては下記入門で解説しております。 dev-k.hatenablog.com 巻き上げとは？ JavaScriptでの巻き上げ(hoisting)は、宣言の前に関数または変数を使用できる動作です。 JavaScriptコンパイラは、エラーが発生しないように、変数と関数のすべての宣言を一番上に移動します。 これは巻き上げと呼ばれます。 なぜこの巻き上げを１つの記事として取り上げるのか それは巻き上げは、多くの開発者にとってJavaScriptの未知のまたは見落とされた概念でもある為です。 中級者ですら巻き上げについてあまり理解されていない方が稀にいらっしゃいます。 しかし、開発者が巻き上げを理解していない場合

Most loved programming language Rust sparks privacy concerns
Rust developers have repeatedly raised concerned about an unaddressed privacy issue over the last few years. Rust has rapidly gained momentum among developers, for its focus on performance, safety, safe concurrency, and for having a similar syntax to C++. StackOverflow's 2020 developer survey ranked Rust first among the "most loved programming languages." However, for the longest time developers h

The Go 1.18 release adds a major new language feature: support for generic programming. In this article I’m not going to describe what generics are nor how to use them. This article is about when to use generics in Go code, and when not to use them. To be clear, I’ll provide general guidelines, not hard and fast rules. Use your own judgement. But if you aren’t sure, I recommend using the guideline

A response to 'A decade of developing a programming language'
I recently read the blog post A decade of developing a programming language by Yorick Peterse (found via Steve Klabnik). I thought it was an interesting blog post which got me thinking, and I have opinions on programming language design from Rust (it is almost exactly a decade since I got involved with Rust too), so I have written a response of sorts. This is all unsubstantiated opinion, so don't

Russ Cox, for the Go team 10 November 2020 Today we celebrate the eleventh birthday of the Go open source release. The parties we had for Go turning 10 seem like a distant memory. It’s been a tough year, but we’ve kept Go development moving forward and accumulated quite a few highlights. In November, we launched go.dev and pkg.go.dev shortly after Go’s 10th birthday. In February, the Go 1.14 relea

Wait! You also have to make a call to WSAStartup() before doing anything else with the sockets library. You pass in the Winsock version you desire to this function (e.g. version 2.2). And then you can check the result to make sure that version is available. The code to do that looks something like this: #include <winsock2.h> { WSADATA wsaData; if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) { fprin
1. One man’s constant is another man’s variable. 2. Functions delay binding; data structures induce binding. Moral: Structure data late in the programming process. 3. Syntactic sugar causes cancer of the semicolon. 4. Every program is a part of some other program and rarely fits. 5. If a program manipulates a large amount of data, it does so in a small number of ways. 6. Symmetry is a complexity-r
