GitHub Actions などで ID token を取ってきてクラウドにログインさせる, package の trusted publishing をする, というのは一般的になってきた。多くは Workload Identity Federation などと呼ばれ、近年はついに AWS も公式で ID token の発行をサポートするようになったし、各種クラウドプロバイダで受入れおよび払出しにだいたい対応しきったといって良いんじゃないだろうか。 GitHub Actions で利用する例は世の中に溢れているが、たとえば AWS や Google Cloud 間での利用や、Terraform での設定方法などはあんまりまとまっていない印象がある。そのため本稿では自分の身の回りで必要な、ID token をベースとしたクラウドプロバイダ間の ID フェデレーション方法、特にそれぞれのク

Why We're All-In on MCPA deep dive into why Mastra is adopting Model Context Protocol (MCP) for AI tool integration, comparing it with Agents.json and Composio, addressing current limitations in discovery, quality, and configuration, and providing a framework-friendly proposal with practical code examples for implementation. Tool integration for AI agents is a mess. Even for developers building ag

この記事は 面白法人グループ Advent Calendar 2025 の5日目の記事です。 はじめに こんにちは！技術部の村上です。 普段はUnityを用いてハイパーカジュアルゲームを作っています。 近年の爆発的な進歩により、AIはもはや日々の開発に欠かせない存在になってきました。中でも今年に入ってからのコーディングエージェントの発展には目を見張るものがあります。 カヤックのハイパーカジュアルゲームチームでは、全員がAIを積極的に利用できるよう制度が整備され、Claude Codeを始めとしたコーディングエージェントを活用して日々開発が行われています。 ところで、コーディングエージェントって実のところ何をやっていて、どう動いて、どう作られているんでしょう？ 私は、動いているモノを見るとそういうのが気になっちゃうのがエンジニアって生き物の生態だと思っています。 そこで今回は、簡易なオリジナ

Why I don't miss React: a story about using the platform - Jack Franklin
May 3, 2022Why I don't miss React: a story about using the platformJust over two years ago I left a role at a London based startup where I lead development of a large, React based e-commerce frontend to join Google to work on Chrome DevTools.

Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

Google API Keys Weren't Secrets. But then Gemini Changed the Rules. ◆ Truffle Security Co.
tl;dr Google spent over a decade telling developers that Google API keys (like those used in Maps, Firebase, etc.) are not secrets. But that's no longer true: Gemini accepts the same keys to access your private data. We scanned millions of websites and found nearly 3,000 Google API keys, originally deployed for public services like Google Maps, that now also authenticate to Gemini even though they
Local-first software: You own your data, in spite of the cloud
Cloud apps like Google Docs and Trello are popular because they enable real-time collaboration with colleagues, and they make it easy for us to access our work from all of our devices. However, by centralizing data storage on servers, cloud apps also take away ownership and agency from users. If a service shuts down, the software stops functioning, and data created with that software is lost. In t

A blank screen and a blinking cursor. That’s all that greeted users when they booted up their machines in the early days of personal computing. No start menu. No icons. Just the command line.

This feature was intended to improve web performance by racing cached requests against the network. Fig 1.
