9am - Open Classes, Open Companies,by Nathaniel Talbott
In this talk Nathaniel reflects upon how features of the Ruby language that make it so efficient can be applied to business. Duck Typing, Interpreted language, Flexibility, Succinctness, Reflection, Open classes. It's a great way to present business concepts to a bunch of Ruby developers. Obie also wrote down some notes.
10am - Mac OS X and Ruby, by Laurent Sansonetti
Laurent is from Apple. Author of 5 Ruby libraries and maintains Ruby inside of OSX. For OSX Leopard, Ruby will be bundled as an OSX framework (Ruby.framework). Support 64bit, universal binary. IRB history support and line editing. Bundle gems (Rake, Rails, Mongrel, Capistrano, Libxml2, SQLit3, DNSDD,...). Ruby can control scriptable applications.
1. RubyAEOSA: app = OSX:AEDesc.application('iTunes')
2. Applescript using RubyAEOSA: result = OSX.do_osascript "tel application 'iTunes'...
3. RubyOSA: new project since June 2006. puts OSA.app('iTunes').current_track.name
RubyOSA is the successor of RubyAEOSA, and is simpler to use and still efficient.
require 'rbosa'
itunes = OSA.app('iTunes')
# Let increase the volume...
100.times { |i| itunes.sound_volume = i; sleep 0.1 }
He will release version 0.1.0 today, it will be available as a gem.
Now onto Cocoa. RubyCocoa, is not Cocoa specific can be used to bridge Ruby with Objective-C code. Is widely used in free and commercials products. Laurent now demos a small Cocoa application written using XCode, in Ruby, to select and control songs in iTunes.
