この記事は「言語実装 Advent Calendar 2025」の3日目の記事です。 この記事は、新しくプログラミング言語を設計する際に文字列型をどうするべきかについて、私の持論をまとめたものです。 以前「新しくプログラミング言語を作る際に数値型をどうするべきか」という記事を書きましたが、この記事はそれの文字列版です。 推敲が足りずに同じことを何箇所かで繰り返している場合がありますが、冗長性だと思ってご容赦ください……。 【2025年12月4日 更新】small string optimization、スライスとGCの話を追加、Rubyの文言の修正、可変性と値セマンティクスの記述の整理など。完全な変更履歴はGitHubを見てください。 【2025年12月7日 更新】ケーススタディーにJava、D、Schemeを追加。JavaScript文字列のコードポイント単位のアクセスの記述を追加。Sw
巨人の肩に乗る
本記事は 仮想通貨 Advent Calendar 2025 の24日目の記事です。 はじめに はじめまして、ymdと申します。普段は、株や暗号資産の分析をし、マーケットが盛り上がったときに落ちているお金を拾っています。 今年のAdvent Calendarを眺めていると、DEXの分析やLLMを活用した自動トレード戦略作成など、非常に有益な記事が目白押しです。 これらを見て思い出したのが、ニュートンの「巨人の肩に乗る」という言葉。本記事では、この精神に倣い、AIの力と先人の知見という2つの「肩」を借りながら、お金拾いの方法を探っていきます。 AIの肩に乗る AI駆動開発の3つのアプローチ AIを活用した開発には、大きく3つの方向性があります： 情報収集の自動化：論文や API ドキュメントの要約 戦略生成の自動化：複数のアプローチを並行生成 コーディングの自動化：コードそのものを AI に
Understanding inheritance and other limitations in Rust - LogRocket Blog
Editor’s note: This Rust guide was updated on 3 Aug, 2022 to include information about doubly linked lists and borrowing things that aren’t static in async code. As a moderator of the Rust subreddit, I regularly happen upon posts about developers’ attempts to transpose their respective language paradigms to Rust, with mixed results and varying degrees of success. In this guide, I’ll describe some
TL;DR; We are changing std::sort in LLVM’s libcxx. That’s a long story of what it took us to get there and all possible consequences, bugs you might encounter with examples from open source. We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can

I read a blog post by Alex Muscar, “Beautiful Binary Search in D“. It describes a binary search called “Shar’s algorithm”. I’d never heard of it and it’s impossible to google, but looking at the algorithm I couldn’t help but think “this is branchless.” And who knew that there could be a branchless binary search? So I did the work to translate it into a algorithm for C++ iterators, no longer requir
3/7/2023 When Zig is safer and faster than Rust There are endless debates online about Rust vs. Zig, this post explores a side of the argument I don't think is mentioned enough. Intro / TLDRλ I was intrigued to learn that the Roc language rewrote their standard library from Rust to Zig. What made Zig the better option? They wrote that they were using a lot of unsafe Rust and it was getting in thei
Toggle dark mode What follows is a brain dump of everything I know about compiling Rust to WebAssembly. Enjoy. 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

Original Zef Interpreter The original Zef interpreter was written with almost no regard for performance. Only two performance-aware choices were made: The value representation is a 64-bit tagged value that may hold a double, a 32-bit integer, or a Object*. Doubles are represented by offsetting them by 0x1000000000000 (a technique I learned from JavaScriptCore; the literature has taken to calling t

V Language Review (2022)
V is a programming language promising to be “Simple, fast, safe, compiled. For developing maintainable software.” V has a controversial past but what is the state of V in 2022? Is V worth checking out? In this post, we’ll take a look at V as it exists in May 2022. TLDR Read the summary Rules of engagement I’ll be using the current version of V built from git which is 50ab2cfd1ae02d4f4280f38c60b8db
Is Rust faster than C?
Is Rust faster than C? Jun 9, 2025 Someone on Reddit recently asked: What would make a Rust implementation of something faster than a C implementation, all things being the same? I think this is a great and interesting question! It’s really tough because it ultimately relies on what exactly you mean by “all things being the same.” And I think this is something that makes it hard to compare languag

This past May, I started a new job working in Rust. I was somewhat skeptical of Rust for a while, but it turns out, it really is all it’s cracked up to be. As a long-time C++ programmer, and C++ instructor, I am convinced that Rust is better than C++ in all of C++’s application space, that for any new programming project where C++ would make sense as the programming language, Rust would make more

It is now 45+ years since C++ was first conceived. As planned, it evolved to meet challenges, but many developers use C++ as if it was still the previous millennium. This is suboptimal from the perspective of ease of expressing ideas, performance, reliability, and maintainability. Here, I present the key concepts on which performant, type safe, and flexible C++ software can be built: resource mana

Why Today’s Python Developers Are Embracing Type Hints | Pyrefly
Python is one of the most successful programming languages out there, with it recently overtaking Javascript as the most popular language on GitHub, according to the latest GitHub Octoverse report. The report emphasises the popularity of the language in the growing fields of AI, data science and scientific computing - fields where speedy experimentation and iteration are critical, and where develo
Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked, like a monster whose “aggro” was pulled by a tank. The reason, of course, is due to a few folks taking issue with my outright dismissal of the C and C++ APIs (and not showi
