Macruby - RubyConf Presentation 2010
This document contains the slides from a presentation about MacRuby. It discusses key aspects of MacRuby including its use of LLVM, ahead-of-time and just-in-time compilation, integration with Cocoa and Objective-C, lack of a global interpreter lock, Grand Central Dispatch API, debugger, ability to create compiled libraries and applications, and potential uses like building App Store apps. Examples are provided of using MacRuby with features like speech synthesis, location services, and the address book.
