    By following the teams that are inventing some of the world's best-loved toys, it spotlights the company's disciplined approach to harnessing creativity and recounts one of the most remarkable business transformations in recent memory. Brick by Brick reveals how LEGO failed to keep pace with the revolutionary changes in kids' lives and began sliding into irrelevance. When the company's leaders implemented some of the business world's most widely espoused prescriptions for boosting innovation, they ironically pushed the iconic toymaker to the brink of bankruptcy. The company's near-collapse shows that what works in theory can fail spectacularly in the brutally competitive global economy. It took a new LEGO management team – faced with the growing rage for electronic toys, few barriers to entry, and ultra-demanding consumers (ten-year old boys) – to reinvent the innovation rule book and transform LEGO into one of the world's most profitable, fastest-growing companies.  Along the way, Brick by Brick reveals how LEGO:- Became truly customer-driven by co-creating with kids as well as its passionate adult fans- Looked beyond products and learned to leverage a full-spectrum approach to innovation- Opened its innovation process by using both the "wisdom of crowds" and the expertise of elite cliques- Discovered uncontested, "blue ocean" markets, even as it thrived in brutally competitive red oceans- Gave its world-class design teams enough space to create and direction to deliver built a culture where profitable innovation flourishes Sometimes radical yet always applicable, Brick by Brick abounds with real-world lessons for unleashing breakthrough innovation in your organization, just like LEGO. Whether you're a senior executive looking to make your company grow, an entrepreneur building a startup from scratch, or a fan who wants to instill some of that LEGO magic in your career, you'll learn how to build your own innovation advantage, brick by brick.

    Written by Peter Morville, author of the groundbreaking Information Architecture for the World Wide Web, the book defines our current age as a state of unlimited findability. In other words, anyone can find anything at any time. Complete navigability.Morville discusses the Internet, GIS, and other network technologies that are coming together to make unlimited findability possible. He explores how the melding of these innovations impacts society, since Web access is now a standard requirement for successful people and businesses. But before he does that, Morville looks back at the history of wayfinding and human evolution, suggesting that our fear of being lost has driven us to create maps, charts, and now, the mobile Internet.The book's central thesis is that information literacy, information architecture, and usability are all critical components of this new world order. Hand in hand with that is the contention that only by planning and designing the best possible software, devices, and Internet, will we be able to maintain this connectivity in the future. Morville's book is highlighted with full color illustrations and rich examples that bring his prose to life.Ambient Findability doesn't preach or pretend to know all the answers. Instead, it presents research, stories, and examples in support of its novel ideas. Are we truly at a critical point in our evolution where the quality of our digital networks will dictate how we behave as a species? Is findability indeed the primary key to a successful global marketplace in the 21st century and beyond. Peter Morville takes you on a thought-provoking tour of these memes and more -- ideas that will not only fascinate but will stir your creativity in practical ways that you can apply to your work immediately.

    Translated into twenty-three languages, it is one of the world's most widely read books on design. In this edition, Victor Papanek examines the attempts by designers to combat the tawdry, the unsafe, the frivolous, the useless product, once again providing a blueprint for sensible, responsible design in this world which is deficient in resources and energy.

    His revelations demystify the strategy behind the company's recent flurry of bold moves, all driven by the pursuit of a business plan unlike any other: to become the indispensable gatekeeper of all the world's information, the one-stop destination for all our information needs. Will Google succeed? And what are the implications of a single company commanding so much information and knowing so much about us? As ambitious as Google's goal is, with 68 percent of all Web searches (and growing), profits that are the envy of the business world, and a surplus of talent, the company is, Stross shows, well along the way to fulfilling its ambition, becoming as dominant a force on the Web as Microsoft became on the PC. Google isn't just a superior search service anymore. In recent years it has launched a dizzying array of new services and advanced into whole new businesses, from the introductions of its controversial Book Search and the irresistible Google Earth, to bidding for a slice of the wireless-phone spectrum and nonchalantly purchasing YouTube for $1.65 billion. Google has also taken direct aim at Microsoft's core business, offering free e-mail and software from word processing to spreadsheets and calendars, pushing a transformative -- and highly disruptive -- concept known as "cloud computing." According to this plan, users will increasingly store all of their data on Google's massive servers -- a network of a million computers that amounts to the world's largest supercomputer, with unlimited capacity to house all the information Google seeks. The more offerings Google adds, and the more ubiquitous a presence it becomes, the more dependent its users become on its services and the more information they contribute to its uni

    The British expected R.101 to spearhead a fleet of imperial airships that would dominate the skies as British naval ships, a century earlier, had ruled the seas. The dream ended when, on its demonstration flight to India, R.101 crashed in France, tragically killing nearly all aboard.Combining meticulous research with superb storytelling, Fatal Flight guides us from the moment the great airship emerged from its giant shed—nearly the largest building in the British Empire—to soar on its first flight, to its last fateful voyage. The full story behind R.101 shows that, although it was a failure, it was nevertheless a supremely imaginative human creation. The technical achievement of creating R.101 reveals the beauty, majesty, and, of course, the sorrow of the human experience.The narrative follows First Officer Noel Atherstone and his crew from the ship’s first test flight in 1929 to its fiery crash on October 5, 1930. It reveals in graphic detail the heroic actions of Atherstone as he battled tremendous obstacles. He fought political pressures to hurry the ship into the air, fended off Britain’s most feted airship pilot, who used his influence to take command of the ship and nearly crashed it, and, a scant two months before departing for India, guided the rebuilding of the ship to correct its faulty design. After this tragic accident, Britain abandoned airships, but R.101 flew again, its scrap melted down and sold to the Zeppelin Company, who used it to create LZ 129, an airship even more mighty than R.101—and better known as the Hindenburg. Set against the backdrop of the British Empire at the height of its power in the early twentieth century,Fatal Flight portrays an extraordinary age in technology, fueled by humankind’s obsession with flight.

    Often, computer science and computer engineering curricula don't provide students with a concentrated and consistent introduction to the fundamental concepts that underlie all computer systems. Traditional computer organization and logic design courses cover some of this material, but they focus largely on hardware design. They provide students with little or no understanding of how important software components operate, how application programs use systems, or how system attributes affect the performance and correctness of application programs. - A more complete view of systems - Takes a broader view of systems than traditional computer organization books, covering aspects of computer design, operating systems, compilers, and networking, provides students with the understanding of how programs run on real systems. - Systems presented from a programmers perspective - Material is presented in such a way that it has clear benefit to application programmers, students learn how to use this knowledge to improve program performance and reliability. They also become more effective in program debugging, because t

    Many accounts of the birth of personal computing have been written, but this is the first close look at the drug habits of the earliest pioneers." --New York TimesMost histories of the personal computer industry focus on technology or business. John Markoff's landmark book is about the culture and consciousness behind the first PCs--the culture being counter- and the consciousness expanded, sometimes chemically. It's a brilliant evocation of Stanford, California, in the 1960s and '70s, where a group of visionaries set out to turn computers into a means for freeing minds and information. In these pages one encounters Ken Kesey and the phone hacker Cap'n Crunch, est and LSD, The Whole Earth Catalog and the Homebrew Computer Lab. What the Dormouse Said is a poignant, funny, and inspiring book by one of the smartest technology writers around.

    Turing Mathematician Alan Turing invented an imaginary computer known as the Turing Machine; in an age before computers, he explored the concept of what it meant to be "computable," creating the field of computability theory in the process, a foundation of present-day computer programming.The book expands Turing's original 36-page paper with additional background chapters and extensive annotations; the author elaborates on and clarifies many of Turing's statements, making the original difficult-to-read document accessible to present day programmers, computer science majors, math geeks, and others.Interwoven into the narrative are the highlights of Turing's own life: his years at Cambridge and Princeton, his secret work in cryptanalysis during World War II, his involvement in seminal computer projects, his speculations about artificial intelligence, his arrest and prosecution for the crime of "gross indecency," and his early death by apparent suicide at the age of 41.
