技術部の笹田（ko1）と遠藤（mame）です。クックパッドで Ruby (MRI: Matz Ruby Implementation、いわゆる ruby コマンド) の開発をしています。お金をもらって Ruby を開発しているのでプロの Ruby コミッタです。 本日 12/25 に、ついに Ruby 3.1.0 がリリースされました（Ruby 3.1.0 リリース ）。今年も Ruby 3.1 の NEWS.md ファイルの解説をします。NEWS ファイルとは何か、は以前の記事を見てください。 プロと読み解く Ruby 2.6 NEWS ファイル - クックパッド開発者ブログ プロと読み解くRuby 2.7 NEWS - クックパッド開発者ブログ プロと読み解くRuby 3.0 NEWS - クックパッド開発者ブログ 本記事は新機能を解説することもさることながら、変更が入った背景や苦労な
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

This blog post hopes to convince you that Python is a compiled language. And by “Python”, I don’t mean alternate versions of Python like PyPy, Mypyc, Numba, Cinder, or even Python-like programming languages like Cython, Codon, Mojo1—I mean the regular Python: CPython! The Python that is probably installed on your computer right now. The Python that you got when you searched “python” on Google and
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub. Table of contents What the pro
This post is an account of why I prefer using the attrs library over Pydantic. I'm writing it since I am often asked this question and I want to have something concrete to link to. This is not meant to be an objective comparison of attrs and Pydantic; I'm not interested in comparing bullet points of features, nor can I be unbiased since I'm a major contributor to attrs (at time of writing, second
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by

Template strings, also known as t-strings, have been officially accepted as a feature in Python 3.14, which will ship in late 2025. 🎉 I'm excited; t-strings open the door to safer more flexible string processing in Python. What's the big idea with t-strings? Since they were introduced in Python 3.6, f-strings have become a very popular way to format strings. They are concise, readable, and powerf
Exactly ten years ago today, we published "Why We Created Julia", introducing the Julia project to the world. At this point, we have moved well past the ambitious goals set out in the original blog post. Julia is now used by hundreds of thousands of people. It is taught at hundreds of universities and entire companies are being formed that build their software stacks on Julia. From personalized me

Type Parameters Proposal
Ian Lance Taylor Robert Griesemer August 20, 2021 StatusThis is the design for adding generic programming using type parameters to the Go language. This design has been proposed and accepted as a future language change. We currently expect that this change will be available in the Go 1.18 release in early 2022. AbstractWe suggest extending the Go language to add optional type parameters to type an

Large Text Compression Benchmark Matt Mahoney Last update: July 3, 2025. history This competition ranks lossless data compression programs by the compressed size (including the size of the decompression program) of the first 109 bytes of the XML text dump of the English version of Wikipedia on Mar. 3, 2006. About the test data. The goal of this benchmark is not to find the best overall compressi
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
The Evolving eBPF Toolchain
These days there is an ever-growing list of tools and frameworks for working with eBPF, all at varying levels of abstraction. There does seem to be a few that sit at the core of the rest of the eBPF ecosystem. However, the ecosystem is changing rapidly, and I’ve found it to be a bit difficult to navigate through the sea of information that’s out there and understand which tools are the current “st
LambdaLisp - A Lisp Interpreter That Runs on Lambda Calculus
LambdaLisp is a Lisp interpreter written as an untyped lambda calculus term. The input and output text is encoded into closed lambda terms using the Mogensen-Scott encoding, so the entire computation process solely consists of the beta-reduction of lambda calculus terms. When run on a lambda calculus interpreter that runs on the terminal, it presents a REPL where you can interactively define and e

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
Fitting a Forth in 512 bytes
Fitting a Forth in 512 bytes June 10, 2021 · 31 minute read This article is part of the Bootstrapping series, in which I start from a 512-byte seed and try to bootstrap a practical system. Software is full of circular dependencies if you look deep enough. Compilers written in the language they compile are the most obvious example, but not the only one. To compile a kernel, you need a running kerne
Last month the V8 team published an excellent blog post on what they call the V8 Sandbox. This isn’t a sandbox for your JavaScript code — it’s intended to mitigate browser exploits caused by bugs in the JIT compiler itself. That’s important work because they report that most Chrome exploits start with a V8 memory safety bug. V8 is written in C++, so it may seem like these are the sort of bugs you’

お役立ちサポート Pythonで文字列を int( ) で変換するときにエラーになるケースと解決方法 ［ＰＲ］ 2021/8/6 2021/8/17 | Python エラー Pythonではint()やfloat()を用いることで「数値の文字列」を数値のデータ（int型やfloat型）に変換できます。 float()は実数を対象としていますが、int()は整数に限定されるので、思わぬところでエラーに遭遇することがあります。今回はそのようなint()でエラーになるケースについて考えます。 int()はPythonの組み込み関数 であり、以下のように「整数の文字列」を引数に指定すると「int型のデータ」に変換できます。 >>> int("123") 123 >>> type(int("123")) <class 'int'> 整数の文字列は全角文字で入力しても、以下のように変換してくれます。
Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo

Java remains one of the most common and popular programming languages in the world because of its strong features. Therefore, it’s no surprise that good Java programmers are very much sought after by almost all organizations across the world – be it startups or large multinational corporations.
