With this concise book, you will quickly gain working knowledge of Sinatra and its minimalist approach to building both standalone and modular web applications. Sinatra serves as a lightweight wrapper around Rack middleware, with syntax that maps closely to functions exposed by HTTP verbs, which makes it ideal for web services and APIs. If you have experience building applications with Ruby, you’ll quickly learn language fundamentals and see under-the-hood techniques, with the help of several practical examples. Then you’ll get hands-on experience with Sinatra by building your own blog engine. Learn Sinatra’s core concepts, and get started by building a simple application Create views, manage sessions, and work with Sinatra route definitions Become familiar with the language’s internals, and take a closer look at Rack Use different subclass methods for building flexible and robust architectures Put Sinatra to work: build a blog that takes advantage of service hooks provided by the GitHub API

    Never before have the cultural powers- that-be been able to exert such control over what we can and can't do with the culture around us. Our society defends free markets and free speech; why then does it permit such top-down control? To lose our long tradition of free culture, Lawrence Lessig shows us, is to lose our freedom to create, our freedom to build, and, ultimately, our freedom to imagine.

    but Kevin "Boingthump" Phenicle could always see more than most people. In the world of phone phreaks, hackers, and scammers, he's a legend. His exploits are hotly debated: could he really get free long-distance calls by whistling into a pay phone? Did his video-game piracy scheme accidentally trigger the first computer virus? And did he really dodge the FBI by using their own wiretapping software against them? Is he even a real person? And if he's ever caught, what would happen to a geek like him in federal prison? Inspired by the incredible stories of real-life hackers, Wizzygig is the thrilling tale of a master manipulator -- his journey from precocious child scammer to federally-wanted fugitive, and beyond. In a world transformed by social networks and data leaks, Ed Piskor's debut graphic novel reminds us how much power can rest in the hands of an audacious kid with a keyboard.

    Kembrew McLeod challenges the blind embrace of privatization as it clashes against our right to free speech and shared resources.Kembrew McLeod is professor of communication studies at the University of Iowa, author of Owning Culture: Authorship, Ownership, and Intellectual Property Law, and coproducer of the documentary Copyright Criminals: This Is a Sampling Sport.Lawrence Lessig is professor of law at Stanford Law School.This book’s documentary companion will be available through Media Education Foundation.

    This book explains in detail exactly how to build one, then how to use it in a range of applications. We discuss materials: where to find them, what to pay and how to make use of found and recycled parts. The section on fire and fuels is thorough but simple; we tried to keep away from numbers wherever possible. There are success stories, case studies, references and where to find further information, all heavily illustrated. Home heating can be expensive both in capital equipment and in running costs. If we heat by gas, oil or electricity we are supporting a big corporation and impoverishing ourselves. By building an extra efficient heating system you will be one more big step off the treadmill and your move to self-sufficiency and true wealth. Good luck with your stove!

    The Motion Picture Association of America, for instance, claimed that in 2005 the film industry lost $2.3 billion in revenue to piracy online. But here Adrian Johns shows that piracy has a much longer and more vital history than we have realized—one that has been largely forgotten and is little understood. Piracy explores the intellectual property wars from the advent of print culture in the fifteenth century to the reign of the Internet in the twenty-first. Brimming with broader implications for today’s debates over open access, fair use, free culture, and the like, Johns’s book ultimately argues that piracy has always stood at the center of our attempts to reconcile creativity and commerce—and that piracy has been an engine of social, technological, and intellectual innovations as often as it has been their adversary. From Cervantes to Sonny Bono, from Maria Callas to Microsoft, from Grub Street to Google, no chapter in the story of piracy evades Johns’s graceful analysis in what will be the definitive history of the subject for years to come.

    Whether exploring electromagnetic fields, the origin of hot chocolate, or DNA fingerprinting, these essays all illustrate the surprisingly circular nature of change. In "Room with (Half) a View," for instance, Burke muses about the partly obscured railway bridge outside his home on the Thames, a musing which sets off a chain of thought that leads from the bridge's engineer to Samuel Morse, to firearms inventor Sam Colt, and finally to a trombonist named Gustav Holst, who once lived in the very house that blocks Burke's view. So it goes with Burke's entertaining and informative essays as each one highlights the interconnectedness of seemingly unrelated events and innovations. Romantic poetry leads to brandy distillation; tonic water connects through Leibniz to the first explorers to reach the North Pole. This unique collection is sure to stimulate and delight history buffs, technophiles, and anyone else with a healthy intellectual curiosity.

    Who are these people, what motivates them, and why should you care?Consider these facts: Everything around us is turning into computers. Your typewriter is gone, replaced by a computer. Your phone has turned into a computer. So has your camera. Soon your TV will. Your car was not only designed on computers, but has more processing power in it than a room-sized mainframe did in 1970. Letters, encyclopedias, newspapers, and even your local store are being replaced by the Internet.Hackers & Painters: Big Ideas from the Computer Age, by Paul Graham, explains this world and the motivations of the people who occupy it. In clear, thoughtful prose that draws on illuminating historical examples, Graham takes readers on an unflinching exploration into what he calls “an intellectual Wild West.”The ideas discussed in this book will have a powerful and lasting impact on how we think, how we work, how we develop technology, and how we live. Topics include the importance of beauty in software design, how to make wealth, heresy and free speech, the programming language renaissance, the open-source movement, digital design, internet startups, and more.

    Gershenfeld offers a glimpse at the brave new post-computerized world, where microchips work for us instead of against us. He argues that we waste the potential of the microchip when we confine it to a box on our desk: the real electronic revolution will come when computers have all but disappeared into the walls around us. Imagine a digital book that looks like a traditional book printed on paper and is pleasant to read in bed but has all the mutability of a screen display. How about a personal fabricator that can organize digitized atoms into anything you want, or a musical keyboard that can be woven into a denim jacket? Gershenfeld tells the story of his Things that Think group at MIT's Media Lab, the group of innovative scientists and researchers dedicated to integrating digital technology into the fabric of our lives.

    You'll progress from a complete beginner regarding Arduino programming and electronics knowledge to intermediate skills and the confidence to create your own amazing Arduino projects.
