A more helpful way to view differences between complex data structures in RSpec. - splitwise/super_diff

On September 9, without warning, Ruby Central kicked out the maintainers who have cared for Bundler and RubyGems for over a decade. Ruby Central made these changes against the established project policies, while ignoring all objections from the maintainers’ team. At the time, Ruby Central claimed these changes were “temporary". However, None of the “temporary” changes made by Ruby Central have been undone, more than six weeks later. Ruby Central still has not communicated with the removed maintainers about restoring any permissions. Ruby Central still has not offered “operator agreements” or “contributor agreements” to any of the removed maintainers. The Ruby Together merger agreement plainly states that it is the maintainers who will decide what is best for their projects, not Ruby Central. Last week, Matz stepped in to assume control of RubyGems and Bundler himself. His announcement states that the Ruby core team will assume control and responsibility for the primary RubyGems and Bundler GitHub repository. Ruby Central did not communicate with any removed maintainers before transferring control of the rubygems/rubygems GitHub repo to the Ruby core team. On October 24th, Shan publicly confirmed she does not believe the maintainers need to be told why they were removed. While we know that Ruby Central had no right to act the way they did, it is nevertheless clear to us that the Ruby community will be better off if the codebase, maintenance, and legal rights to RubyGems and Bundler are all together in the same place.

If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects.

Amazon CloudFront は、AWS ネイティブの Content Delivery Network (CDN) サービスです。CDN は、エンドユーザーにより近い世界中のエッジロケーションのネットワークを使用し、エッジでコンテンツをキャッシュすることで、Web アクセラレーションを提供します。しかし、CloudFront はそれ以上のことができます。エッジでの機能として、地理的フィルタリング、関数の実行、AWS Web Application Firewall (WAF) フィルタリングの実行など、さまざまな機能を備えています。この投稿では、CloudFront ディストリビューションへのクライアントリクエストのライフサイクルを探求し、特にこれらの機能の実行順序に注目します。この理解は、Web アプリケーションの配信最適化、Web アプリケーションのセキュリティ保護、および CDN 設定のトラブルシューティングにおいて不可欠です。
