Allan Kaprow's 'happenings' and 'environments' were the precursors to contemporary performance art, and his essays are some of the most thoughtful, provocative, and influential of his generation. His sustained inquiry into the paradoxical relationship of art to life and into the nature of meaning itself is brought into focus in this newly expanded collection of his most significant writings. A new preface and two new additional essays published in the 1990s bring this valuable collection up to date.

The Cocoa Touch frameworks and APIs are powerful tools for creating native iOS apps, and they're free with Xcode, Apple's development environment. If you've already gotten your feet wet with Objective-C, and you're ready to learn more about iOS development, then Learn Cocoa Touch for iOS is the book for you. You'll learn on the job - building cool apps as you read through the book that will teach you what you need to know to use Cocoa Touch and prepare you for creating your own apps. Learn Cocoa Touch for iOS shows you how to use frameworks like MapKit, Twitter, and MediaPlayer. You'll also learn about hardware APIs so you can get the most out of your accelerometer, camera, and more. You'll even learn about more advanced features like Grand Central Dispatch. A home inventory management system A live-updating Twitter client A photo browser with an animated slideshow If you're ready for the next step toward becoming a Cocoa Touch master, this is the book for you.

This project is designed to educate and instruct the public about various ways that are currently and immediately practical to address serious issues that now surround the topics of fuel, transportation and utilities. These issues include both the high costs and shortages (perceived or real) now involved, as well as the environmental impacts of either immediately and actively addressing or not addressing these current problems. This publication focuses on the many things that can be done even when the general public does not have effective cooperation or support from their governmental authorities.

Foreword by Jeff Kelley. Nevada's open spaces have long inspired complex responses from a population largely shaped by European sensibilities toward land and its uses. In Mapping the Empty Fox considers how eight of the state's most distinguished and innovative contemporary artists have responded to the harsh, enigmatic landscapes of the Great Basin and how, through their work, they have expressed and helped to define our attitudes toward the space we call the West. The artists are Jim McCormick, Rita Deanin Abbey, Dennis Parks, Walter McNamara, Robert Beckmann, Michael Heizer, Bill Barker, and Mary Ann Bonjorni.

Objective-C the language of choice for iOS and OS X development, is a decades-old language built upon the C language. It's powerful and dynamic nature allow you to write incredible software, and it's C underpinnings allow you to write performance-heavy code as well. Advanced Objective-C takes you on a tour for Objective-C's inner workings. You'll learn the details about how Objective-C really works, how to use runtime features like dynamically created classes, and how to work with JSON-created objects. You'll also learn compiler shortcuts, and you'll get the inside picture on what's happening in ARC. Finally, you learn about class clusters, using SQLite-backed NSArray, and how to write truly safe Objective-C code. Pro Objective-C breaks your understanding of the language down into its component parts and then reassembles them into powerful knowledge that unlocks your ability to write better, faster, and safer code.
