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 3.0.0 がリリースされました。一昨年、昨年に続き、今年も Ruby 3.0 の NEWS.md ファイルの解説をします。NEWS ファイルとは何か、は一昨年の記事を見てください（なお Ruby 3.0.0 から、NEWS.md にファイル名を変えました）。 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 Ruby 3.0 は、Ruby にとってほぼ 8 年ぶりのメジャーバージョンア
防衛省サイバーコンテスト 2025 writeup - st98 の日記帳 - コピー
2/2に12時間というちょうどよい競技時間で開催された。21時終了だったけれども、11時45分ぐらいに最速で全完して1位🎉 第1回以来4年ぶりの優勝だ。昨年大会の第4回ではヒントの閲覧数で優勝を逃してしまって悔しい思いをしたので、雪辱を果たすことができ嬉しい。開始直後からずっと1位を独走できており、450名以上のプレイヤーがいる中で圧勝だったのも嬉しい。 昨年度や一昨年度はバルクが作問を担当していたが、今回はAGESTが担当していた。これまでの問題と比較すると全体的に易化したように思うが、解くにあたって発想の大きな飛躍を必要とするいわゆる「エスパー要素」のある問題はごく一部を除いて存在しておらず*1、よかったと思う。また、昨年度・一昨年度に引き続きwriteupは公開可能というのもよかった。 戦略というほどの戦略は立てていなかったけれども、とりあえずWebを見た後は全カテゴリを上から見て
TabFS
Going through the files inside a tab's folder. For example, the url.txt, text.txt, and title.txt files tell me those live properties of this tab (Read more up-to-date documentation for all of TabFS's files here.) This gives you a ton of power, because now you can apply all the existing tools on your computer that already know how to deal with files -- terminal commands, scripting languages, point-
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
This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines? Every programmer today is familiar with function calls (subroutines): F calls G, which stops F and runs G. G does its work, potentially calling and waiting for other functions, and eventually returns. When G returns, G is gone and F continues running. In this pattern, only one fu
NETGEAR社製ルーターにおける認証不要の任意コード実行の技術的解説(PSV-2022-0044) - GMO Flatt Security Blog

January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
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
copilot-explorer
Copilot Internals | thakkarparth007.github.io Github Copilot has been incredibly useful to me. It can often magically read my mind and make useful suggestions. The thing that surprised me the most was its ability to correctly “guess” functions/variables from surrounding code – including from other files. This can only happen, if the copilot extension sends valuable information from surrounding cod
GitHub Actions を静的検査するツールの紹介 (actionlint/ghalint/zizmor)
先日、 tj-actions/changed-files や reviewdog/action-* などのアクションの Git タグが書き換えられるという出来事がありました。 これにより、これらのアクションを Git タグで参照している GitHub Actions Workflow 内で悪意のあるコードが実行されてしまうという事態が発生しました。 このような事態を防ぐためには、アクションの参照には Git タグではなくコミットハッシュを使用するなどの対策が必要です。 # ❌ Git タグは書き換えられる可能性がある - uses: actions/checkout@v4 - uses: actions/checkout@v4.2.2 # ⭕ コミットハッシュを指定しておけば Git タグが書き換えられても影響を受けない - uses: actions/checkout@11bd71901
型安全かつシンプルなAgentフレームワーク「PydanticAI」の実装を解剖する - ABEJA Tech Blog
はじめに こちらはABEJAアドベントカレンダー2024 12日目の記事です。 こんにちは、ABEJAでデータサイエンティストをしている坂元です。最近はLLMでアプローチしようとしていたことがよくよく検証してみるとLLMでは難しいことが分かり急遽CVのあらゆるモデルとレガシーな画像処理をこれでもかというくらい詰め込んだパイプラインを実装することになった案件を経験して、LLMでは難しそうなことをLLM以外のアプローチでこなせるだけの引き出しとスキルはDSとしてやはり身に付けておくべきだなと思うなどしています（LLMにやらせようとしていることは大抵難しいことなので切り替えはそこそこ大変）。 とはいうものの、Agentの普及によってより複雑かつ高度な推論も出来るようになってきています。弊社の社内外のプロジェクト状況を見ていても最近では単純なRAG案件は減りつつあり、計画からアクションの実行、結果
Programming is an iterative process - as much as we would like to come up with the perfect solution from the start, it rarely works that way. Good programs often start as quick prototypes. The bad ones stay prototypes, but the best ones evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best approach before
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

Today we’re excited to announce the release of TypeScript 4.8! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. These types let you put your expectations and assumptions into your code, and those assumptions can then be checked by the TypeScript type-checker. This checking can help avoid typos, calling uninitialized values, mixing up

Vjeux » Birth of Prettier
React Conf is around the corner and it's been almost 10 years since Prettier was released. I figured it would be a good time to recount the journey from its early days to now. This is the story of how the "Space vs Tabs Holy War" ended, not through one side winning over the other but instead a technological invention making it the underlying source of tensions no longer being a thing. Back Story S
When people say “debuggers are useless and using logging and unit-tests is much better,” I suspect many of them think that debuggers can only put breakpoints on certain lines, step-step-step through the code, and check variable values. While any reasonable debugger can indeed do all of that, it’s only the tip of the iceberg. Think about it; we could already step through the code 40 years ago, sure

Rust is an appealing language for building user interfaces for a variety of reasons, especially the promise of delivering both performance and safety. However, finding a good architecture is challenging. Architectures that work well in other languages generally don’t adapt well to Rust, mostly because they rely on shared mutable state and that is not idiomatic Rust, to put it mildly. It is sometim

Improving the Developer Experience with the Ruby LSP - Shopify
Improving the Developer Experience with the Ruby LSPThe Ruby LSP is a new language server built at Shopify that makes coding in Ruby even better by providing extra Ruby features for any editor that has a client layer for the LSP.

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th

It is December. That means annoying Christmas things are everywhere, including but not limited to the annual programming semi-competition known as Advent of Code. The problem with Advent of Code is that it is a waste of time. Most of the puzzles are in the realm of either string processing (somewhat applicable to programming), logic puzzles (not really applicable to most programming), or stupid go
This paper reflects work done in late 2022 and 2023 to audit for vulnerabilities in terminal emulators, with a focus on open source software. The results of this work were 10 CVEs against terminal emulators that could result in Remote Code Execution (RCE), in addition various other bugs and hardening opportunities were found. The exact context and severity of these vulnerabilities varied, but some
My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise. I once tried that before with the Classic protocol (the one from 2009), but I quickly realized there wasn't really a way to properly parse binary data in bash. Take the following code sample: function a() { read -n 2 uwu echo
