    Part intellectual journey, part memoir, Hamlet's BlackBerry sets out to solve what William Powers calls the conundrum of connectedness. Our computers and mobile devices do wonderful things for us. But they also impose an enormous burden, making it harder for us to focus, do our best work, build strong relationships, and find the depth and fulfillment we crave.Hamlet's BlackBerry argues that we need a new way of thinking, an everyday philosophy for life with screens. To find it, Powers reaches into the past, uncovering a rich trove of ideas that have helped people manage and enjoy their connected lives for thousands of years. New technologies have always brought the mix of excitement and stress that we feel today. Drawing on some of history's most brilliant thinkers, from Plato to Shakespeare to Thoreau, he shows that digital connectedness serves us best when it's balanced by its opposite, disconnectedness.Using his own life as laboratory and object lesson, Powers demonstrates why this is the moment to revisit our relationship to screens and mobile technologies, and how profound the rewards of doing so can be. Lively, original, and entertaining, Hamlet's BlackBerry will challenge you to rethink your digital life.

    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.

    A dirty little secret assembly language programmers rarely admit to, however, is that what you really need to learn is machine organization, not assembly language programming. Write Great Code Vol I, the first in a series from assembly language expert Randall Hyde, dives right into machine organization without the extra overhead of learning assembly language programming at the same time. And since Write Great Code Vol I concentrates on the machine organization, not assembly language, the reader will learn in greater depth those subjects that are language-independent and of concern to a high level language programmer. Write Great Code Vol I will help programmers make wiser choices with respect to programming statements and data types when writing software, no matter which language they use.

    How easy is easy? It's not like an instant cake mix: just add water and stir. Dynamic web design is--well-- dynamic. Every website is different, so it's impossible to grab a script, paste it into a web page, and expect it to work. Building dynamic sites involves diving into the code and adju- ing it to your own requirements. If that thought makes you break out in a cold sweat, just relax for a moment. PHP is not difficult, and I've written this book very much with the n- programmer in mind. I've done so because I don't come from a computing background myself. In fact, I went to school in the days before pocket calculators were invented, never mind personal computers. As a result, I don't assume that you drank in knowledge of arrays, loops, and conditional statements with your mother's milk. Everything is explained in plain, straightforward l- guage, and I've highlighted points where things may go wrong, with advice on how to solve the problem. At the same time, if you're working with computers and websites, you're bound to have a certain level of technical knowledge and skill. So I don't talk down to you either.

Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

    Inspirational and poetic, this book will not only spark readers’ creative energies, but also reawaken your passion for life.In 2005, as a husband, father, and corporate employee — Lorenzo's life revolved around home, work, and his daily commute from the suburbs to the city.Then, one day, he found himself staying at the Little Church in midtown Manhattan in the wake of a marital separation. Living in virtual isolation for three months, he had a rare chance to re-examine his life.Quite unexpectedly, he found himself wandering around the city to take photographs, a passion he had let slide in the years of pursuing a career and starting a family.
