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
React・Node.js・CloudflareWorkersでRustから作成したWASMを動かす - iimon TECH BLOG
こんにちは！iimonでCTOをしているもりごです。 本記事はiimon Advent Calendar 2024最終日の記事となります！ 今年はふるさと納税で沖縄に沢山寄付をしたので、沖縄の名産品を食べるのが毎日の楽しみとなっています。 今回、フロントエンド・サーバーサイド・エッジコンピューティングの3つの環境でWASM（WebAssembly）を活用し、同じ処理を別の環境で動かす方法を試してみました。複数の環境で共通の処理を使う事ができれば、同じコードを複数の環境に記述する必要がなくなり、管理の煩雑さを軽減できると考えて試してみました。 例えばフォームのバリデーションのように、フロントエンドとサーバーサイドの両方で同じ処理が必要になるケースはよくあると思っています。弊社は不動産領域を扱っており、住所関連の処理で色々な場所で同じ処理が必要になることが多々ありました。これまでは、なるべく１
Fast Rust Builds
Sep 4, 2021 It’s common knowledge that Rust code is slow to compile. But I have a strong gut feeling that most Rust code out there compiles much slower than it could. As an example, one fairly recent post says: With Rust, on the other hand, it takes between 15 and 45 minutes to run a CI pipeline, depending on your project and the power of your CI servers. This doesn’t make sense to me. rust-analyz

The string is arguably the most essential data type in programming — every programming language and software in the world uses strings in one way or another. It enables humans to easily communicate with sophisticated programs and machines. One thing that would help you a lot as a programmer is understanding how to use and manipulate strings so that you can build programs users love. Regular expres

PowerShell: the object-oriented shell you didn’t know you needed
PowerShell is an interactive shell and scripting language from Microsoft. It’s object-oriented — and that’s not just a buzzword, that’s a big difference to how the standard Unix shells work. And it is actually usable as an interactive shell. Getting Started PowerShell is so nice, Microsoft made it twice. Specifically, there concurrently exist two products named PowerShell: Windows PowerShell (5.1)
Regex engine internals as a library - Andrew Gallant's Blog
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata, which exposes much of the regex crate internals as their own APIs for others to use. To my knowledge, this is the first regex library to expose its interna

Julia 1.0 came out well over 2 years ago. Since then a lot has changed and a lot hasn’t. Julia 1.0 was a commitment to no breaking changes, but that is not to say no new features have been added to the language. Julia 1.6 is a huge release and it is coming out relatively soon. RC-1 was released recently. I suspect we have at least a few more weeks before the final release. The Julia Core team take

General interview tipsClarify any assumptions you made subconsciously. Many questions are under-specified on purpose. Always validate input first. Check for invalid/empty/negative/different type input. Never assume you are given the valid parameters. Alternatively, clarify with the interviewer whether you can assume valid input (usually yes), which can save you time from writing code that does in
