GitHubリリースという、GitHubでタグに対してリリースノートを書ける機能があります。 このリリースノート機能は、パーマネントリンクもあるし、Markdownも書けるし、画像もアップロードできるし、絵文字でリアクションもできるし、RSSもあるし、通知機能もあるし、GitHub Discussion連携すればコメントも書けるし、全文検索もついてくるしこれブログとして使えるんじゃないかと思いました。 そういう発想から、GitHubリリースノートをブログとして運用するためのちょっとしたブログシステムを作って使っています。 次のリポジトリが実際に動いてるものです。 azu/book-review: 本を読んだ感想を書くブログです。 リリースの一覧を見ると本の感想の記事が並んでいます。 Releases · azu/book-review Release 伴走型支援: 新しい支援と社会のカタチ
Sponsored by: Honeycomb — AI agents behave unpredictably. Get the context you need to debug what actually happened. Read the blog 31st January 2022 Release notes are an important part of the open source process.

Sometimes, C/C++ projects have a long development cycle. When working on such a project, it can be easy to take our development environment for granted, and forget about the effort invested in its bring-up. The build environment works like magic, the test framework is neatly integrated, and the CI/CD pipeline relieves us of tedious, repetitive tasks. For me, all it took was a simple thought: How d
Introducing Claude 4

こんにちは！ROUTE06 Software Engineerの@yoshida-m-3です。 GitHub Projectsがアップデートを続けていることは知っていましたが、実際のプロジェクトで使用できるかは確証がありませんでした。そこでチーム内でGitHub Projectsの勉強会を開催し、実際に検証することにしました。 見るべき人に見るべき情報を確実に届けたい プロジェクト情報の管理において、「各関係者に適切な粒度で情報を確実に届けること」が重要だと考えています。 情報の可視化にはカンバンを使うことが多いですが、情報が多いと重要な情報が隠れてしまう可能性があります。 情報の粒度は見るべき人の立場によって異なります。エンジニアはIssue単位の情報が必要ですが、プロダクトオーナー・マネージャーはEpic単位の情報が必要であり、時系列の進捗情報も必要な場合があります。 GitHub P
AWS deleted my 10-year account and all data without warning
After 10 years as an AWS customer and open-source contributor, they deleted my account and all data with zero warning. Here's how AWS's 'verification' process became a digital execution, and why you should never trust cloud providers with your only copy of anything. On July 23, 2025, AWS deleted my 10-year-old account and every byte of data I had stored with them. No warning. No grace period. No r

My AI Adoption Journey
My experience adopting any meaningful tool is that I've necessarily gone through three phases: (1) a period of inefficiency (2) a period of adequacy, then finally (3) a period of workflow and life-altering discovery. In most cases, I have to force myself through phase 1 and 2 because I usually have a workflow I'm already happy and comfortable with. Adopting a tool feels like work, and I do not wan

To learn more, we sat down with employees across Anthropic to understand how they use Claude Code at work. While many of their use cases were pred
Update: We've published Agent Skills as an open standard for cross-platform portability. (December 18, 2025) Since launching Skills, two of the biggest questions we’ve heard from customers are: "How do skills and MCP work together? When should I use one versus the other?" Model Context Protocol (MCP) connects Claude to third-party tools, and skills teach Claude how to use them well. When you combi

Over the past year, a new pattern has emerged in attacks on the open source supply chain. Attackers are focusing on exfiltrating secrets (like API keys) in order to both publish malicious packages from an attacker-controlled machine as well as gain access to more projects in order to propagate the attack. These attacks often start by compromising a workflow on GitHub Actions. Let’s talk through wh

Beyond agentic coding
I'm generally pretty pro-AI with one major exception: agentic coding. My consistent impression is that agentic coding does not actually improve productivity and deteriorates the user's comfort and familiarity with the codebase. I formed that impression from: my own personal experiences Every time I use agentic coding tools I'm consistently unimpressed with the quality of the results. my experience

TypeScript can use this information to help you avoid about mistakes like typos, missing arguments, or forgetting
What We Learned from a Year of Building with LLMs (Part I)
It’s an exciting time to build with large language models (LLMs). Over the past year, LLMs have become “good enough” for real-world applications. The pace of improvements in LLMs, coupled with a parade of demos on social media, will fuel an estimated $200B investment in AI by 2025. LLMs are also broadly accessible, allowing everyone, not just ML engineers and scientists, to build intelligence into
Today we are excited to announce the beta release of TypeScript 4.7!
