FastAPI入門 - モダンなPythonフレームワークの特性をチュートリアルで手軽に学ぶ｜ハイクラス転職・求人情報サイト アンビ（AMBI）
FastAPI入門 - モダンなPythonフレームワークの特性をチュートリアルで手軽に学ぶ PythonのWebフレームワークとしていま注目を集めるFastAPIは、シンプルにコードが書けるだけでなく、パフォーマンスが高いWebアプリケーションのバックエンドサーバーが構築可能です。同フレームワークの勘所をPythonスペシャリストの杜世橋さんが、初心者向けのハンズオン、そしてより実践的な画像への自動タグ付けサービス実装をとおして解説します。 FastAPIはいま非常に注目されているPythonのWebフレームワークの1つです。Flaskのようにシンプルに書ける一方でPythonのType Hintの機能をうまく活用し、HTTPのリクエスト/レスポンスをPythonの関数の引数/戻り値とシームレスにマッピングして非常に効率的に開発ができるのが最大の特徴です。非同期処理にも対応していてその名

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased

C# Advent Calendar 2021の参加記事となっています。去年は2個エントリーしたあげく、1個すっぽかした（！）という有様だったので、今年は反省してちゃんと書きます。 スクレイピングに関しては10年前にC#でスクレイピング:HTMLパース(Linq to Html)のためのSGMLReader利用法という記事でSGMLReaderを使ったやり方を紹介していたのですが、10年前ですよ、10年前！さすがにもう古臭くて、現在ではもっとずっと効率的に簡単にできるようになってます。 今回メインで使うのはAngleSharpというライブラリです。AngleSharp自体は2015年ぐらいからもう既に定番ライブラリとして、日本でも紹介記事が幾つかあります。が、いまいち踏み込んで書かれているものがない気がするので、今回はもう少しがっつりと紹介していきたいと思っています。それと直近Visual

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog

In this post I’ll walk through the full implementation of a Virtual DOM in a bit over 200 lines of JavaScript. The result is a full-featured and sufficiently performant virtual DOM library (demos).

How MDN’s autocomplete search works – Mozilla Hacks - the Web developer blog

This is the story about how that’s implemented. If you stick around to the end, I’ll share an “easter egg” feature that, once you’ve learned it, will make you look really cool at dinner parties.

Some time ago, I wrote a blog post on how to compile C to WebAssembly without Emscripten, i.e. without the default tool that makes that process easy. In Rust, the tool that makes WebAssembly easy is called wasm-bindgen, and we are going to ditch it! At the same time, Rust is a bit differe

Why XML Comments matter XML is a popular format for storing and sharing data. It was explicitly designed for people and programs to read and write data.[1] From spreadsheets to save states, most modern software and games parse and write XML. XML comments are special notes that parsers should not treat as data. XML comments start with <!-- and end with -->. Technically XML comments must not contain

The 1980s and 1990s saw the genesis of Perl, Ruby, Python, PHP and JavaScript: interpreted, dynamically-typed programming languages which favored ease of use and flexibility over performance. In many ways, these programming languages are a product of the surrounding context. The 90s were the peak of the dot-com hype, and CPU clock speeds were still doubling roughly every 18 months. It looked like
In this tutorial, you'll learn how the React compiler can help you write more optimized React applications. React is a user interface library that has been doing its job quite well for over a decade.

How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look
