This reduces memory usage of Symbols; because GC couldn’t collect Symbols before R
MooseX - a new Ruby DSL for Object Oriented Programming (and much more)
MooseX is a postmodern object DSL for Ruby This is a DSL for object creation, aspects, method delegation and much more. It is based on Perl 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 can create attributes, methods, the entire constructor and much more. But I can’t find something sim
Ruby's OptionParser Is All You Need
Software engineer at BitLove. A New Yorker. I love the web and a good cup of coffee. This may be the last text on building command line apps with Ruby you'll ever have to read. There are a lot of Ruby gems that help you build command line 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

Lazy Ruby 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. Because Haskell makes it easy to define lists and is lazy, the code for defining an infini
linuxwell - by Radek Pazdera
linuxwell 30 Mar 2014 Terminal colours made simple Over the weekend, I pushed out the first release of the tco gem. Its goal is to make working with terminal colours as simple as possible; hence the name tco. The main feature of this tool is the way it works with colours. Instead of an oddly organised sequence of colour codes, tco uses simple RGB. It provides a library for your Ruby gems and apps,

Learn how RubyGems works, and how to make your own. The RubyGems software allows you to easily download, install, and use ruby software packages on your system. The software package is called a “gem” which contains a packaged Ruby application or library. Gems can be used to extend or modify functionality in Ruby applications. Commonly they’re used to distribute reusable functionality that is share
How to tune a guitar with Ruby and FFT
Hi, my name is Anatoli, I'm a Software Engineer from Berlin. During the day I work in Growth Team @ Blinkist. During the night I'm an Indie Maker of SQL Habit – online course that teaches data and SQL for Product and Marketing from 0 to Advanced. From time to time, when nobody sees me, I like to play the guitar and every time I face a challenge – how to tune it properly. And like in any other case
分散テスト実行システムRRRSpecをリリースしました - クックパッド開発者ブログ
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 the Build a Ruby Gem Ebook, which is now available for sale in 3 packages, including 14 chapters of code and over 2 hours of screencasts. The world isn’t black and white (as much as we’d like to believe it is). Just because our gem’s functionality may work for us, doesn’t mean it’ll work for everyone. Fortunately, we can give users the abi
