MacRuby, an Objective-C based Ruby implementation is now available in version 0.4.
Among the new features is an embedding API ("Runtime Objective-C API") which allows to use MacRuby for scripting the host application. InfoQ previously reported on the API.
HotCocoa (added in MacRuby 0.3), makes it easy to integrate with Cocoa frameworks, eg. for building GUIs. A new feature now is HotCocoa::Graphics:
Inspiration for this project was derived from Processing and NodeBox. These excellent Java- and Python-based graphics programming environments are mature and full-featured, but HCG offers similar functionality using the elegant Ruby programming language and the power of native graphics processing on Mac hardware.
Processing is a Java-based langage for visualization. _why's Ruby Shoes also offers similar visualization capabilities.
The HotCocoa::Graphics blog provides a list of sample code (complete with graphical output).
For performance matters, MacRuby 0.4 now runs the GC on a separate thread, and also includes DTrace probes, which among other things can report on GC activity (DTrace sample scripts for MacRuby).
Among other changes, MacRuby 0.4 comes with Ruby 1.9.1 libraries, 64 bit support, as well as improved integration with XCode.
MacRuby is now available for download.

Brian Marick takes us through a quick tour of the most important values and challenges to adopting Agile successfully (they aren't the typical challenges and values we hear in the community).
The line between development and architecture is tricky. Does it exist at all? Is an ivory tower actually needed? There's a balance in the middle, but how do you move from developer to architect?
The word 'authority' sometimes produces an allergic response in hard-line agilists. Freedom and authority – both are bad if misused and both are good if used in right spirit for a noble cause.
"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?
Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.
Heroku's Adam Wiggins talks about Rails, Background Jobs, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity on what architecture is.
