A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.

    Doing something that’s genuinely better is very hard.” —Jony IveIn 1997, Steve Jobs returned to Apple as CEO with the unenviable task of turning around the company he had founded. One night, Jobs discovered a scruffy British designer toiling away at Apple’s corporate headquarters, surrounded by hundreds of sketches and prototypes. It was then that Jobs realized he had found a talent who could reverse the company’s long decline.That young designer was Jony Ive. Jony Ive’s collaboration with Jobs would produce some of the world’s most iconic technology products, including the iMac, iPod, iPad, and iPhone. The designs have not only made Apple a hugely valuable company, they’ve overturned entire industries, built a loyal fan base, and created a globally powerful brand. Along the way, Jony Ive has become the world’s leading technology innovator, won countless design awards, earned a place on the 2013 Time 100 list, and was even knighted for his “services to design and enterprise.”Yet despite his triumphs, little is known about the shy and soft-spoken whiz whom Jobs referred to as his “spiritual partner” at Apple. Jony Ive reveals the true story of Apple’s real innovator-in-chief.Leander Kahney, the bestselling author of Inside Steve’s Brain, offers a detailed portrait of a creative genius. He shows us how Jony Ive went from an English art school student with dyslexia to the man whose immense insights have altered the pattern of our lives. From his early interest in industrial design, fostered by his designer father, through his education at Newcastle Polytechnic and meteoric rise at Apple, we discover the principles and practices that he developed to become the designer of his generation.Based on interviews with Jony Ive’s former colleagues and Kahney’s own familiarity with the world of Apple, this book gives insight into how Jony Ive (now senior vice president of design) has redefined the ways in which we work, entertain, and communicate with one another.

    Designed for readers who don't need the academic formality, it's a fast and easy computer science guide. It teaches essential concepts for people who want to program computers effectively. First, it introduces discrete mathematics, then it exposes the most common algorithms and data structures. It also shows the principles that make computers and programming languages work.

    Cracking the PM Interview is a comprehensive book about landing a product management role in a startup or bigger tech company. Learn how the ambiguously-named "PM" (product manager / program manager) role varies across companies, what experience you need, how to make your existing experience translate, what a great PM resume and cover letter look like, and finally, how to master the interview: estimation questions, behavioral questions, case questions, product questions, technical questions, and the super important "pitch."

    Some books try to give you copy-and-paste instructions for how to deal with every single system issue that may arise, but How Linux Works actually shows you how the Linux system functions so that you can come up with your own solutions. After a guided tour of filesystems, the boot sequence, system management basics, and networking, author Brian Ward delves into open-ended topics such as development tools, custom kernels, and buying hardware, all from an administrator's point of view. With a mixture of background theory and real-world examples, this book shows both "how" to administer Linux, and "why" each particular technique works, so that you will know how to make Linux work for you.

    At the center of this change are Apple and Google, two companies whose philosophies, leaders, and commercial acumen have steamrolled the competition. In the age of the Android and the iPad, these corporations are locked in a feud that will play out not just in the marketplace but in the courts and on screens around the world.     Fred Vogelstein has reported on this rivalry for more than a decade and has rare access to its major players. In Dogfight, he takes us into the offices and board rooms where company dogma translates into ruthless business; behind outsize personalities like Steve Jobs, Apple’s now-lionized CEO, and Eric Schmidt, Google’s executive chairman; and inside the deals, lawsuits, and allegations that mold the way we communicate. Apple and Google are poaching each other’s employees. They bid up the price of each other’s acquisitions for spite, and they forge alliances with major players like Facebook and Microsoft in pursuit of market dominance.     Dogfight reads like a novel: vivid nonfiction with never-before-heard details. This is more than a story about what devices will replace our phones and laptops. It’s about who will control the content on those devices and where that content will come from—about the future of media in Silicon Valley, New York, and Hollywood.

    Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.

    The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

     At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on...something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code. You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design pattern. Most importantly, you want to learn the "secret language" of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You'll easily counter with your deep understanding of why Singleton isn't as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter. With Head First Design Patterns, you'll avoid the embarrassment of thinking Decorator is something from the "Trading Spaces" show. Best of all, in a way that won't put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts. If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.

    Alibaba’s $25 billion IPO in 2014 was the largest global IPO ever. A Rockefeller of his age who is courted by CEOs and Presidents around the world, Jack is an icon for China’s booming private sector and the gatekeeper to hundreds of millions of middle class consumers.Duncan Clark first met Jack in 1999 in the small apartment where Jack founded Alibaba.

How did he outsmart rival entrepreneurs from China and Silicon Valley? Can Alibaba maintain its 80% market share? As it forges ahead into finance and entertainment, are there limits to Alibaba’s ambitions?  How does the Chinese government view its rise?  Will Alibaba expand further overseas, including in the U.S.?Clark tells Alibaba’s tale in the context of China’s momentous economic and social changes, illuminating an unlikely corporate titan as never before.

    It can almost be summed up by the button on every page: "Buy now with one click."Why has Amazon been so successful? Much of it has to do with Jeff Bezos, the CEO and founder, whose unique combination of character traits and business strategy have driven Amazon to the top of the online retail world.Richard Brandt charts Bezos's rise from computer nerd to world- changing entrepreneur. His success can be credited to his forward-looking insights and ruthless business sense. Brandt explains: Why Bezos decided to allow negative product reviews, correctly guessing that the earned trust would outweigh possible lost sales. Why Amazon zealously guards some patents yet freely shares others. Why Bezos called becoming profitable the "dumbest" thing they could do in 1997. How Amazon.com became one of the only dotcoms to survive the bust of the early 2000s. Where the company is headed next.Through interviews with Amazon employees, competitors, and observers, Brandt has deciphered how Bezos makes decisions. The story of Amazon's ongoing evolution is a case study in how to reinvent an entire industry, and one that anyone in business today ignores at their peril.

    In a new chapter for this edition that brings the story up-to-date, Nicholas Carr revisits the dramatic new world being conjured from the circuits of the "World Wide Computer."
