Rails 3.2 Released
DHH has unveiled Rails 3.2! Not quite as big a deal as 3.1 but has a faster development mode, faster route recognition, a tagged logger, and more. With Rails master now aiming at 4.0.0, it seems 3.2 may be the last version of Rails to support Ruby 1.8. Read More

RSpec 2.8: The Popular Ruby BDD Tool Goes Supersonic
RSpec 2.8 and rspec-rails 2.8.1 have been released and some users have been reporting significant performance improvements.

RSpec 2.8: The Popular Ruby BDD Tool Goes Supersonic

8 Comments

By Peter Cooper / January 7, 2012

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!

Maybe.. maybe not.. but the Ruby and Rails job market is as hot as ever, so if you’re looking for a new position, be sure to negotiate well! ;-)

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

16 Comments

By Peter Cooper / December 15, 2011

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.

The Technologies We’ll Be Using

If you’re part of the “meh, JRuby” brigade, suspend your disbelief for a minute. JRuby is easy to install, easy to use, and isn’t going to trample all over your system or suck up all your memory. Read More

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

7 Comments

By Peter Cooper / December 14, 2011

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.

An interesting quirk of Scandinavian society is the concept of Jante Law. It knocks down standing out and being individual, in favor of communal harmony. It’s typically used in a negative context to lament restrictions and lack of risk taking within Nordic society (DHH touched on this briefly in a recent Mixergy interview) but the flip side of the Jante coin is lagom: the idea and ideal of having just the right amount of something.

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

5 Comments

By Peter Cooper / December 13, 2011

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 News and Releases in 2011: A Retrospective

3 Comments

By Peter Cooper / December 7, 2011

2011 is drawing to a close and I have been reminded of a post I made about a year ago: Ruby in 2010: A Retrospective of a Great Year for Ruby. 2010 was a stunning year with the release of Ruby 1.9.2, MacRuby 0.5, Sinatra 1.0, Rubinius 1.0, and DataMapper 1.0!

This year, MagLev, Capybara, Cucumber, RefineryCMS, OmniAuth and TorqueBox all hit their 1.0 milestones, but I’ve dug through the archives to see what else 2011 brought for the Ruby scene.

Headlines

Rails 3.1.3 Released (Very Quickly After 3.1.2)
This release mainly contains fixes for regressions that popped up in 3.1.2, including a downgrade to Sprockets. 3.1.2 itself was primarily a bug and security fix release and cleared up a XSS vulnerability in the translate helper.

Rails 3.0.11 Released (clears up aforementioned security vuln too)

Ruby’s Unary Operators and How to Define Their Functionality

16 Comments

By Peter Cooper / November 8, 2011

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 +).

Ruby only has a handful of unary operators, and while it’s common to redefine binary operators like + or [] to give your objects some added syntactic sugar, unary operators are less commonly redefined. Read More

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

9 Comments

By Peter Cooper / November 7, 2011

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.

Why Gemify the Standard Library? Read More
