Book SynopsisAs with any subculture, Apple fans have their own customs, obsessions, and rites of passage - from waiting in line to spend thousands of dollars on the newest Apple product, to attending Macworld year after year. This thoroughly revised edition of The Cult of Mac takes us into the world of today's Apple fan with sections covering things like an opera based on the life of Steve Jobs, repurposing old Macs, professional photography taken with iPhones, Mac Museums created by fans around the world, as well as how Apple Inc. and its public face has changed following the death of Steve Jobs.Trade ReviewPraise for the first edition of Cult of Mac: "Kahney embarked on his journey to chronicle the weird world of Mac addicts last year, and I think he nailed it. If you have iPod-clutching, Macintosh-using, Woz-loving, Newton-worshiping cultists in your circle of friends, get 'em this book. But even if you you're not a HyperCard-carrying member of the club, the book is worth a look. Kahney has uncovered some real characters on the scene.” —San Francisco Chronicle"Mr. Kahney's informal history of the Mac is interspersed with trivia and delightful details, and intriguing photos, and is wrapped up in an entertaining style. This is a coffee table book that only a geek might love — but it's also one lots of people will enjoy reading." —Washington Times"This account of Macintosh fanaticism will strike a chord with anyone who's ardently defended (or cursed) an operating system... sure to end up on Quadra-based coffee tables everywhere." —Wired MagazineWinner: Outstanding Book of the Year — Most Unique Design.

Book SynopsisA study of the relationship between platform and creative expression in the Atari VCS, the gaming system for popular games like Pac-Man and Star Wars: The Empire Strikes Back.The Atari Video Computer System dominated the home video game market so completely that “Atari” became the generic term for a video game console. The Atari VCS was affordable and offered the flexibility of changeable cartridges. Nearly a thousand of these were created, the most significant of which established new techniques, mechanics, and even entire genres. This book offers a detailed and accessible study of this influential video game console from both computational and cultural perspectives. Studies of digital media have rarely investigated platforms—the systems underlying computing. This book, the first in a series of Platform Studies, does so, developing a critical approach that examines the relationship between platforms and creative expression.Nick Mo

Book Synopsis Learn how to use Solidity and the Ethereum project - second only to Bitcoin in market capitalization. Blockchain protocols are taking the world by storm, and the Ethereum project, with its Turing-complete scripting language Solidity, has rapidly become a front-runner. This book presents the blockchain phenomenon in context; then situates Ethereum in a world pioneered by Bitcoin. See why professionals and non-professionals alike are honing their skills in smart contract patterns and distributed application development. You''ll review the fundamentals of programming and networking, alongside its introduction to the new discipline of crypto-economics. You''ll then deploy smart contracts of your own, and learn how they can serve as a back-end for JavaScript and HTML applications on the Web.Many Solidity tutorials out there today have the same flaw: they are written for advanced JavaScript developers who want to transfer their skills to a blockchain enviroTable of Contents1.

Book SynopsisOver 60 recipes and solutions for inventors, makers, and budding engineers to create projects using the BeagleBone Black About This Book • Learn how to develop applications with the BeagleBone Black and open source Linux software • Sharpen your expertise in making sophisticated electronic devices • Explore the BeagleBone Black with this easy-to-succeed recipe format Who This Book Is For If you are a hardware, Linux, and/or microcomputing novice, or someone who wants more power and possibilities with product prototypes, electronic art projects, or embedded computing experiments, then this book is for you. It is for Internet of Things enthusiasts who want to use more sophisticated hardware than the Raspberry Pi or the Arduino can provide. Whether you are an engineering student, a DIYer, an inventor, or a budding electronics enthusiast, this book delivers accessible, easy-to-succeed instructions for using an advanced microcomputing platform. What You Will Learn • Set up and run the BeagleBone Black for the first time • Learn the basics of microcomputing and Linux using the command line and easy kernel mods • Make introductory projects with Python, JavaScript, BoneScript, and Node.js • Explore physical computing and simple circuits using buttons, LEDs, sensors, and motors • Discover the unique features of the BeagleBone Black and its real-time computing functions • Build intermediate level audio and video applications • Assemble and add ingredients for creating Internet of Things prototypes In Detail There are many single-board controllers and computers such as Arduino, Udoo, or Raspberry Pi, which can be used to create electronic prototypes on circuit boards. However, when it comes to creating more advanced projects, BeagleBone Black provides a sophisticated alternative. Mastering the BeagleBone Black enables you to combine it with sensors and LEDs, add buttons, and marry it to a variety of add-on boards. You can transform this tiny device into the brain for an embedded application or an endless variety of electronic inventions and prototypes. With dozens of how-tos, this book kicks off with the basic steps for setting up and running the BeagleBone Black for the first time, from connecting the necessary hardware and using the command line with Linux commands to installing new software and controlling your system remotely. Following these recipes, more advanced examples take you through scripting, debugging, and working with software source files, eventually working with the Linux kernel. Subsequently, you will learn how to exploit the board's real-time functions. We will then discover exciting methods for using sound and video with the system before marching forward into an exploration of recipes for building Internet of Things projects. Finally, the book finishes with a dramatic arc upward into outer space, when you explore ways to build projects for tracking and monitoring satellites. Style and approach This comprehensive recipe book deconstructs a complex, often confusing piece of technology, and transforms it to become accessible and fun with snappy, unintimidating prose, and extensive easy-to-succeed instructions.
