缶つぶし機とソフトウェア移行技術 - Refactoring to Rust の読書感想文 - じゃあ、おうちで学べる
はじめに ——あるいは、「知っている」と「理解している」の間 Rustのことは、知っていた。学習もしていた。実務でも使っていた。 でも、それは知っているつもりだった。 知ってるつもり 無知の科学 (ハヤカワ文庫NF) 作者:スティーブン スローマン,フィリップ ファーンバック早川書房Amazon 日々Rustで開発し、BoxとRcとArcを使い分け、tokio::spawnでタスクを生成し、?演算子を当たり前のように書いている。FFI？PyO3使えばいいでしょ。WebAssembly？wasm-bindgenがあるじゃない。技術的には、確かに「使える」レベルにはあった。 でも、心のどこかで感じていた違和感があった。 オートバイのエンジンを分解できる人と、エンジンが動く原理を理解している人は違う。コードが動くことと、なぜそう書くべきかを理解することも違う。私は前者だった。メカニックではあった
`X-Forwarded-For`ヘッダからクライアントのIPアドレスを取得する - Magnolia Tech
2022/7/24: Plack::Middleware::ReverseProxyが、X-Forwarded-Forをサポートしていますよ、と教えていただいたので、記載を修正しました。 @karupanerura++ Scalatra 3.0.0-M1がリリースされた。Scala3対応だ、めでたい。 github.com 最近Scalatraへあまり貢献できていなかったので、いくつかのコンパイル時の警告を消すPRを出した。コードを見直す中で、ふとX-Forwarded-ForヘッダからクライアントのIPアドレスを取得する箇所が目にとまった。 /** * The remote address the client is connected from. * This takes the load balancing header X-Forwarded-For into account *

Modular Errors in Rust
It is thankfully common wisdom nowadays that documentation must be placed as near as possible to the code it documents, and should be fine-grained to a minimal unit of describability (the thing being documented). The practice provides numerous benefits to the codebase and project as a whole: When editing the source code, contributors are less likely to forget to update the documentation as well, e
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

HTML Whitespace is Broken September 2, 2024Recently, I was working on a project which required a deeper understanding of how whitespace works in HTML. I was never a fan of HTML's whitespace behavior before as I've been burned by it a few times. But as I dug into it more deeply, I found myself discovering complex design issues that I wanted to explore in a blog post. This is partially to write down

Announcing PowerShell Crescendo Preview.1 - PowerShell Team
As a shell, PowerShell is intended to work with native commands in addition to cmdlets. However, native commands have their own unique syntax, sometimes containing many subcommands and parameters/switches, and are often like its own language. Wouldn’t it be great to have an option to leverage your PowerShell skills to use new commands or be even more proficient with native commands you are already
