Your customers want rock-solid, bug-free software that does exactly what they expect it to do. Yet they can't always articulate their ideas clearly enough for you to turn them into code. The Cucumber Book dives straight into the core of the problem: communication between people. Cucumber saves the day; it's a testing, communication, and requirements tool - all rolled into one.

RSpec 2.8: The Popular Ruby BDD Tool Goes Supersonic

RSpec 2.8 has been released, along with rspec-rails 2.8.1 for the full Rails 3.x integration experience.

RSpec is a BDD-focused testing tool that's particularly popular in the Rails world where everyone except DHH is using it (if you believe the hoopla). RSpec has faced accusations of being less than speedy in the past, but it seems 2.8 has had a performance firework shoved up its tailpipe:

David Chelimsky, the creator of RSpec, also notes that in RSpec 2.8:

• the documentation has been significantly improved
• there's improved support for tags and filtering
• random example running order support (with user definable seed)
• rspec --init will create a spec directory and some starter code on a blank project - ideal for Ruby library development!

Let’s Build a Simple Video Game with JRuby: A Tutorial

Ruby isn't known for its game development chops despite having a handful of interesting libraries suited to it. Java, on the other hand, has a thriving and popular game development scene flooded with powerful libraries, tutorials and forums. Can we drag some of Java's thunder kicking and screaming over to the world of Ruby? Yep! - thanks to JRuby. Let's run through the steps to build a simple 'bat and ball' game now.

A Lagom Review of O’Reilly’s ‘Sinatra Up and Running’

Sinatra Up and Running is a new book published by O'Reilly and written by Alan Harris and Konstantin Hasse that covers the popular Sinatra web application DSL in a brisk 103 pages, acting as a tutorial to newcomers and a handy reference for old hands.

TLDR: It's a short, sweet, relatively cheap and very well written book about Sinatra. Recommended. Buy here.

Ludum Dare for Rubyists: An Online 48 Hour Game Coding Competition

Ludum Dare is an online accelerated game development event that focuses on regular 48 hour competitions. Think Rails Rumble but for games! It's been around since 2002 but has had a big publicity boost recently due to the participation of Notch, the creator of the mind-bogglingly popular indie game Minecraft.

The next Ludum Dare contest is taking place this coming weekend between December 16-19, 2011 and I want to encourage Rubyists to take part. The competition tends to be dominated by Java, Flash, Microsoft XNA developers, and HTML5 developers, so it'd be great to see more Ruby entries (of which there have only been a couple so far)....

Ruby’s Unary Operators and How to Define Their Functionality

In math, a unary operation is an operation with a single input. In Ruby, a unary operator is an operator which only takes a single 'argument' in the form of a receiver. For example, the - on -5 or ! on !true.

In contrast, a binary operator, such as in 2 + 3, deals with two arguments. Here, 2 and 3 (which become one receiver and one argument in a method call to +).

The Ruby Standard Library To Be Converted to Gems for Ruby 2.0?

The Ruby standard library (a.k.a. stdlib) is a collection of Ruby libraries that, at one time or another, have been considered useful enough to include with the MRI Ruby implementation by standard. Due to the popularity of these libraries, other Ruby implementations have then tended to re-implement or include the standard library too.

As part of the march toward Ruby 2.0, the state of Ruby's 'standard library' has come up for discussion. A popular line of thinking (and IMHO, very likely to actually happen) is that the standard library should be 'gemified' for Ruby 2.0.

Seven Languages in Seven Weeks

You should learn a programming language every year, as recommended by The Pragmatic Programmer. But if one per year is good, how about Seven Languages in Seven Weeks? In this book you'll get a hands-on tour of Clojure, Haskell, Io, Prolog, Scala, Erlang, and Ruby. Whether or not your favorite language is on that list, you'll broaden your perspective of programming by examining these languages side-by-side. You'll learn something new from each, and best of all, you'll learn how to learn a language quickly.

Ruby 2.0 Release Schedule Announced: Roll on 2013!

What Ruby’s ||= (Double Pipe / Or Equals) Really Does

In Rubyists Already Use Monadic Patterns, Dave Fayram made a passing reference to using ||= to set a variable's value if its value were 'Nothing' (false or nil in Ruby). The resulting Reddit quickly picked up on his definition (which was fixed later) and argued about ||='s true meaning which isn't as obvious as many Rubyists think. This spread to Freenode's awesome #ruby-lang IRC channel where I picked it up.

Abstract (or the TLDR Version)

A common misconception is that a ||= b is equivalent to a = a || b, but it behaves like a || a = b

The Last Week in Ruby: Rails 3.1.1, Sinatra Recipes, Spree Gets Funded and more

Back in 2008 and 2009, Ruby Inside had a long line of "Interesting Ruby Tidbits That Don’t Need Separate Posts" posts, aimed at sharing a collection of news and libraries in one hit. In the last year, I've shifted Ruby Inside to focusing on less frequent tutorials or investigative features and have been putting all of the news on Ruby Weekly, my weekly newsletter.

There are still many, though, who would prefer to read the news in their RSS readers or on the Web, so I'm going to be taking the things I find for Ruby Weekly each week, doing a little reformatting, and sharing them here on Ruby Inside too. The longer articles will then slot in nicely in between :-)

On August 1, 2011, Ruby 1.9.3 preview 1 was released. The final version isn't yet out (as of September 23) but Ruby 1.9.3 is going to be the next, full production-level release of MRI Ruby. But what's the deal with 1.9.3 (and its successors, Ruby 1.9.4 and 2.0)? Keep reading!

The Ruby 1.9 Walkthrough: How to Go From Ruby 1.8.7 to 1.9.2 and 1.9.3

In a presentation about Ruby 1.9.3, Yuki Sonoda notes that Ruby 1.8 has "no future" and its "end of life" is being discussed pretty seriously. Ruby 1.8 is becoming history, but what's the alternative? Why, Ruby 1.9! :-)

Even amongst the groups I'm involved with, I've seen a lot of resistance to Ruby 1.9. Sometimes it's because of deployment or library concerns, but often there's a hesitancy over what's changed, what's new, or what has been flat out removed from 1.9. So I've been working on something to help out.. because I think Ruby 1.9 is awesome and everyone should be taking it seriously ASAP.

A MiniTest::Spec Tutorial: Elegant Spec-Style Testing That Comes With Ruby

Despite RSpec's awesomeness, Test::Unit remains the most popular Ruby testing tool out there outside of Rails apps. I've recently been code walking through a lot of Ruby libraries for my Ruby Reloaded course and the typical arrangement is Test::Unit, sometimes coupled with Shoulda or Contest for some extra syntactic sweetness.

Part of the reason for Test::Unit's enduring popularity is its presence in the Ruby standard library but, also, its general 'lightness' and speed. When you're writing a large app, using a powerful full-featured system like RSpec has significant benefits (particularly stakeholder involvement in writing the specs). But when you're working on a library that might spread far and wide and is aimed solely at developers, the pros of Test::Unit shine through.

22 Ruby and Rails Jobs for August 2011 (With Even Some Junior Ones)

It seems the Ruby and Rails job scenes are on fire! I don't remember running so many jobs across a single month before. 22 Ruby and Rails jobs are here and they're spanning the world. US West Coast, East Coast, England, Scotland and Germany are all represented. It's definitely not the common "San Francisco or nothing" roundup :-)

Also fresh this time around is the mention of "all levels" or "junior" roles. At least a few of the jobs listed here today are open to all skill levels or are explicitly junior in nature. I've had a lot of readers get in touch requesting more listings like these so I'm glad they've come along.

rbenv is a new lightweight Ruby version management tool built by Sam Stephenson (of 37signals and Prototype.js fame).

The established leader in the Ruby version management scene is RVM but rbenv is an interesting alternative if you want or need something significantly lighter with fewer features. Think of it as a bit like Sinatra and Rails. It's not about which is the best, it's about which is better for you and your current requirements.
