Being Digital is both a guide to the present state of our rapidly-changing digital age and a map for the future--how our lives will be shaped and enhanced by computer-related technology. Negroponte--Wired Magazine columnist and founding director of the MIT Media Lab--describes how advancements in computer technology and telecommunications will transform workplaces, households, and educational institutions. He explains how this revolution will change the way we live, think, and interact with one another and with technology, and foresees the challenges that lie ahead in developing truly global systems for delivering multimedia and other forms of digitally based information. Negroponte characterizes the development of future information delivery systems as a battle between atoms, the components of books and other physical resources, and bits, the basic building blocks of information.
The digital age is coming, Negroponte says, and it "cannot be denied or stopped....We're discussing a fundamental cultural change: Computing is not about computers, it's about life; being digital is not just being a geek or Internet surfer or mathematically savvy child, it's actually a way of living and is going to impact absolutely everything."
-- Hartley Rogers, Jr., Professor, Massachusetts Institute of Technology Combinatorics research, the branch of mathematics that deals with the study of discrete, usually finite, structures, covers a wide range of problems not only in mathematics but also in the biological sciences, engineering, and computer science. "The Handbook of Combinatorics" brings together almost every aspect of this enormous field and is destined to become a classic. Ronald L. Graham, Martin Grö tschel, and Lá szló Lová sz, three of the world's leading combinatorialists, have compiled a selection of articles that cover combinatorics in graph theory, theoretical computer science, optimization, and convexity theory, plus applications in operations research, electrical engineering, statistical mechanics, chemistry, molecular biology, pure mathematics, and computer science.

The nonfiction debut from the author of the international bestseller "Sacred Games" about the surprising overlap between writing and computer coding
Vikram Chandra has been a computer programmer for almost as long as he has been a novelist. In this extraordinary new book, his first work of nonfiction, he searches for the connections between the worlds of art and technology. Coders are obsessed with elegance and style, just as writers are, but do the words mean the same thing to both? Can we ascribe beauty to the craft of writing code?
Exploring such varied topics as logic gates and literary modernism, the machismo of tech geeks, the omnipresence of an "Indian Mafia" in Silicon Valley, and the writings of the eleventh-century Kashmiri thinker Abhinavagupta, "Geek Sublime" is both an idiosyncratic history of coding and a fascinating meditation on the writer's art. Part literary essay, part technology story, and part memoir, it is an engrossing, original, and heady book of sweeping ideas.

Dialogic: Education for the Internet Age argues that despite rapid advances in communications technology, most teaching still relies on traditional approaches to education, built upon the logic of print, and dependent on the notion that there is a single true representation of reality. In practice, the use of the Internet disrupts this traditional logic of education by offering an experience of knowledge as participatory and multiple.
This new logic of education is dialogic and characterises education as learning to learn, think and thrive in the context of working with multiple perspectives and ultimate uncertainty. The book builds upon the simple contrast between observing dialogue from an outside point of view, and participating in a dialogue from the inside, before pinpointing an essential feature of dialogic: the gap or difference between voices in dialogue which is understood as an irreducible source of meaning. Each chapter of the book applies this dialogic thinking to a specific challenge facing education, re-thinking the challenge and revealing a new theory of education.
Areas covered in the book include:
The challenge identified in Wegerif's text is the growing need to develop a new understanding of education that holds the potential to transform educational policy and pedagogy in order to meet the realities of the digital age. Dialogic: Education for the Internet Age draws upon the latest research in dialogic theory, creativity and technology, and is essential reading for advanced students and researchers in educational psychology, technology and policy.
Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work.
Ever since Homo sapiens has walked the earth, natural selection has favored perception that hides the truth and guides us toward useful action, shaping our senses to keep us alive and reproducing. We observe a speeding car and do not walk in front of it; we see mold growing on bread and do not eat it. These impressions, though, are not objective reality. Just like a file icon on a desktop screen is a useful symbol rather than a genuine representation of what a computer file looks like, the objects we see every day are merely icons, allowing us to navigate the world safely and with ease.
The real-world implications for this discovery are huge. From examining why fashion designers create clothes that give the illusion of a more "attractive" body shape to studying how companies use color to elicit specific emotions in consumers, and even dismantling the very notion that spacetime is objective reality, The Case Against Reality dares us to question everything we thought we knew about the world we see.
An exploration of how and why social media content is tagged as "not safe for work" and an argument against conflating sexual content with risk.
The hashtag #NSFW (not safe for work) acts as both a warning and an invitation. NSFW tells users, "We dare you to click on this link! And by the way, don't do it until after work!" Unlike the specificity of movie and television advisories ("suggestive dialogue," "sexual content"), NSFW signals, nonspecifically, sexually explicit content that ranges from nude selfies to pornography. NSFW looks at how and why social media content is tagged "not safe" and shows how this serves to conflate sexual content and risk. The authors argue that the notion of "unsafety" extends beyond the risk of losing one's job or being embarrassed at work to an unspecified sense of risk attached to sexually explicit media content and sexual communication in general.
The authors examine NSFW practices of tagging and flagging on a range of social media platforms; online pornography and its dependence on technology; user-generated NSFW content--in particular, the dick pic and associated issues of consent, desire, agency, and social power; the deployment of risqué humor in the workplace; and sexist and misogynist online harassment that functions as an enforcer of inequalities. They argue against the categorical effacement of sexual content by means of an all-purpose hashtag and urge us to shift considerations of safety from pictorial properties to issues of context and consent.
"Filled with wisdom and thought experiments and things that will mess with your mind." -- Neil Gaiman, author of The Graveyard Book and American GodsIn sharply argued, fast-moving chapters, Cory Doctorow's Information Doesn't Want to Be Free takes on the state of copyright and creative success in the digital age. Can small artists still thrive in the Internet era? Can giant record labels avoid alienating their audiences? This is a book about the pitfalls, and the opportunities, creative industries (and individuals) are confronting today--about how the old models have failed or found new footing, and about what might soon replace them. An essential read for anyone with a stake in the future of the arts, Information Doesn't Want to Be Free offers a vivid guide to the ways creativity and the Internet interact today, and to what might be coming next.
"Perfectly placed to tell us what's really new about [the] second-generation Web."--Los Angeles Times
Business visionary and bestselling author David Weinberger charts how as business, politics, science, and media move online, the rules of the physical world--in which everything has a place--are upended. In the digital world, everything has its places, with transformative effects:
- Information is now a social asset and should be made public, for anyone to link, organize, and make more valuable.
- There's no such thing as "too much" information. More information gives people the hooks to find what they need.
- Messiness is a digital virtue, leading to new ideas, efficiency, and social knowledge.
- Authorities are less important than buddies. Rather than relying on businesses or reviews for product information, customers trust people like themselves.
With the shift to digital music standing as the model for the future in virtually every industry, Everything Is Miscellaneous shows how anyone can reap rewards from the rise of digital knowledge.

"A definitive document of a world in transition: I won't be alone in returning to Uncanny Valley for clarity and consolation for many years to come." --Jia Tolentino, author of Trick Mirror: Reflections on Self-Delusion
The prescient, page-turning account of a journey in Silicon Valley: a defining memoir of our digital age
In her mid-twenties, at the height of tech industry idealism, Anna Wiener--stuck, broke, and looking for meaning in her work, like any good millennial--left a job in book publishing for the promise of the new digital economy. She moved from New York to San Francisco, where she landed at a big-data startup in the heart of the Silicon Valley bubble: a world of surreal extravagance, dubious success, and fresh-faced entrepreneurs hell-bent on domination, glory, and, of course, progress.
Anna arrived amidst a massive cultural shift, as the tech industry rapidly transformed into a locus of wealth and power rivaling Wall Street. But amid the company ski vacations and in-office speakeasies, boyish camaraderie and ride-or-die corporate fealty, a new Silicon Valley began to emerge: one in far over its head, one that enriched itself at the expense of the idyllic future it claimed to be building.
Part coming-age-story, part portrait of an already-bygone era, Anna Wiener's memoir is a rare first-person glimpse into high-flying, reckless startup culture at a time of unchecked ambition, unregulated surveillance, wild fortune, and accelerating political power. With wit, candor, and heart, Anna deftly charts the tech industry's shift from self-appointed world savior to democracy-endangering liability, alongside a personal narrative of aspiration, ambivalence, and disillusionment.
Unsparing and incisive, Uncanny Valley is a cautionary tale, and a revelatory interrogation of a world reckoning with consequences its unwitting designers are only beginning to understand.
