    This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.

    It covers topics such as Zend Engine, XML support, SQLite, and others.

    It's a book about the fate of one idea--that the Internet might liberate us forever from government, borders, and even our physical selves. We learn of Google's struggles with the French government and Yahoo's capitulation to the Chinese regime; of how the European Union sets privacy standards on the Net for the entire world; and of eBay's struggles with fraud and how it slowly learned to trust the FBI. In a decade of events the original vision is uprooted, as governments time and time again assert their power to direct the future of the Internet. The destiny of the Internet over the next decades, argue Goldsmith and Wu, will reflect the interests of powerful nations and the conflicts within and between them.While acknowledging the many attractions of the earliest visions of the Internet, the authors describe the new order, and speaking to both its surprising virtues and unavoidable vices. Far from destroying the Internet, the experience of the last decade has lead to a quiet rediscovery of some of the oldest functions and justifications for territorial government. While territorial governments have unavoidable problems, it has proven hard to replace what legitimacy governments have, and harder yet to replace the system of rule of law that controls the unchecked evils of anarchy. While the Net will change some of the ways that territorial states govern, it will not diminish the oldest and most fundamental roles of government and challenges of governance.Well written and filled with fascinating examples, including colorful portraits of many key players in Internet history, this is a work that is bound to stir heated debate in the cyberspace community.

    according to an artificial intelligence trained by scientist Janelle Shane, creator of the popular blog "AI Weirdness." She creates silly AIs that learn how to name paint colors, create the best recipes, and even flirt (badly) with humans--all to understand the technology that governs so much of our daily lives.We rely on AI every day for recommendations, for translations, and to put cat ears on our selfie videos. We also trust AI with matters of life and death, on the road and in our hospitals. But how smart is AI really, and how does it solve problems, understand humans, and even drive self-driving cars?Shane delivers the answers to every AI question you've ever asked, and some you definitely haven't--like, how can a computer design the perfect sandwich? What does robot-generated Harry Potter fan-fiction look like? And is the world's best Halloween costume really "Vampire Hog Bride"?In this smart, often hilarious introduction to the most interesting science of our time, Shane shows how these programs learn, fail, and adapt--and how they reflect the best and worst of humanity. You Look Like a Thing and I Love You is the perfect book for anyone curious about what the robots in our lives are thinking.
