Many new features and improvements are included for the increasingly diverse and expanding demands forRuby. For example, Symbol GC makes Symbols garbage collectable.

MooseX is a postmodern object DSL forRuby This is a DSL for objectcreation, aspects, method delegation and much more.It is based onPerl Moose and Moo, two important modules who add a better way of Object Orientation development (and I enjoy A LOT). Using a declarative stype, using Moose/Moo you cancreate attributes, methods, the entire constructor and much more. But I can’t find somethingsim
Software engineer at BitLove. A New Yorker. I love the web and agood cup of coffee. This may be the lasttext onbuilding commandline apps withRuby you'll ever have to read. There are a lot ofRuby gems that help youbuild commandline apps. Thor, Escort, CRI, GLI, Methadone, and executable,just to name a few. While results have varied, I've had my share of hangups with these gems. I get the w
LazyRuby Lazy Evaluation and Recursive Lists In Haskell,it is possible to construct infinite lists via recursive definition. This is only possible because Haskell uses lazy evaluation rather than eager evaluation. Otherwise, the entire list would need to be calculated and the program would never terminate.

技術部アルバイトの鈴木(@draftcode)です。クックパッドが内部向けに開発・運用を行ってきた、分散テスト実行システムRRRSpecをオープンソースとして公開しました。RRRSpecは時間のかかる自動テストを分散処理することで、全体のテスト時間の短縮を狙うアプリケーションです。現在クックパッドでは17000を超えるテスト項目があり、マシン一台でテストを実行すると完了まで数時間かかります。このテストを60並列程度の分散処理で行うことで、平均8分から9分程度で完了できるようになりました。また、Amazon EC2のスポットインスタンスを利用することにより、大幅なコスト削減も同時に達成しました。 https://github.com/cookpad/rrrspec 分散テスト実行とは アプリケーションが大きくなるにつれて、自動テストの数も大きくなっていきます。クックパッドでは、非常に多くの
This is one of the final post leading up the the launch of theBuild aRuby Gem Ebook, which is now available for sale in 3 packages, including 14 chapters of code and over 2 hours of screencasts.
