    It has made countless new businesses possible and presents a massive opportunity for large enterprises to innovate like startups and retire decades of technical debt. But making the most of the cloud requires much more from enterprises than just a technology change. Stephen Orban led Dow Jones’s journey toward digital agility as their CIO and now leads AWS’s Enterprise Strategy function, where he helps leaders from the largest companies in the world transform their businesses. As he demonstrates in this book, enterprises must re-train their people, evolve their processes, and transform their cultures as they move to the cloud. By bringing together his experiences and those of a number of business leaders, Orban shines a light on what works, what doesn’t, and how enterprises can transform themselves using the cloud.

    This wonderfully accessible book illuminates the professional and personal paths that led him to this remarkable conclusion.All interactions between particles in the universe, Lloyd explains, convey not only energy but also information—in other words, particles not only collide, they compute. And what is the entire universe computing, ultimately? “Its own dynamical evolution,” he says. “As the computation proceeds, reality unfolds.”To elucidate his theory, Lloyd examines the history of the cosmos, posing questions that in other hands might seem unfathomably complex: How much information is there in the universe? What information existed at the moment of the Big Bang and what happened to it? How do quantum mechanics and chaos theory interact to create our world? Could we attempt to re-create it on a giant quantum computer? Programming the Universe presents an original and compelling vision of reality, revealing our world in an entirely new light.

    Sure, HTML started as a mere markup language, but more recently HTML’s put on some major muscle. Now we’ve got a language tuned for building web applications with Web storage, 2D drawing, offline support, sockets and threads, and more. And to speak this language you’ve got to go beyond HTML5 markup and into the world of the DOM, events, and JavaScript APIs. Now you probably already know all about HTML markup (otherwise known as structure) and you know all aboutCSS style (presentation), but what you’ve been missing is JavaScript (behavior). If all you know about are structure and presentation, you can create some great looking pages, but they’re still just pages. When you add behavior with JavaScript, you can create an interactive experience; even better, you can create full blown web applications.Head First HTML5 Programming is your ultimate tour guide to creating web applications with HTML5 and JavaScript, and we give you everything you need to know to build them, including: how to add interactivity to your pages, how to communicate with the world of Web services, and how to use the great new APIs being developed for HTML5. Here are just some of the things you’ll learn in Head First HTML5 Programing:Learn how to make your pages truly interactive by using the power of the DOM.Finally understand how JavaScript works and take yourself from novice to well-informed in just a few chapters.Learn how JavaScript APIs fit into the HTML5 ecosystem, and how to use any API in your web pages.Use the Geolocation API to know where your users are.Bring out your inner artist with Canvas, HTML5’s new 2D drawing surface.Go beyond just plugging a video into your pages, and create custom video experiences.Learn the secret to grabbing five megabytes of storage in every user’s browser.Improve your page’s responsiveness and performance with Web workers.And much more.

    As the size and complexity of commercial software have grown, the gap between academic computer science and industry has widened. It's an open secret that there is little engineering in software engineering, which continues to rely not on codified scientific knowledge but on intuition and experience.Barr, who worked as a programmer for more than twenty years, describes how the industry has evolved, from the era of mainframes and Fortran to today's embrace of the cloud. He explains bugs and why software has so many of them, and why today's interconnected computers offer fertile ground for viruses and worms. The difference between good and bad software can be a single line of code, and Barr includes code to illustrate the consequences of seemingly inconsequential choices by programmers. Looking to the future, Barr writes that the best prospect for improving software engineering is the move to the cloud. When software is a service and not a product, companies will have more incentive to make it good rather than "good enough to ship."

    If you want to leverage OpenGL 2.1's major improvements, you really need the Fourth Edition. It's a comprehensive tutorial, systematic API reference, and massive code library, all in one. You'll start with the fundamental techniques every graphics programmer needs: transformations, lighting, texture mapping, and so forth. Then, building on those basics, you'll move towards newer capabilities, from advanced buffers to vertex shaders. Of course, OpenGL's cross-platform availability remains one of its most compelling features. This book's extensive multiplatform coverage has been thoroughly rewritten, and now addresses everything from Windows Vista to OpenGL ES for handhelds. This is stuff you absolutely want the latest edition for. A small but telling point: This book's recently been invited into Addison-Wesley's OpenGL Series, making it an "official" OpenGL book -- and making a powerful statement about its credibility. Bill Camarda, from the August 2007 href="http://www.barnesandnoble.com/newslet... Only

    Stories about weaknesses in cybersecurity like the "Heartbleed" leak, or malicious software on the cash registers at your local Target have become alarmingly common. Even more alarming is the sheer number of victims associated with these crimes--the identities and personal information of millions is stolen outright as criminals drain bank accounts and max out credit cards. The availability of stolen credit card information is now so common that it can be purchased on the black market for as little as four dollars with potentially thousands at stake for the victims. Possibly even more catastrophic are hackers at a national level that have begun stealing national security, or economic and trade secrets. The world economy and geopolitics hang in the balance.In Cyberphobia, Edward Lucas unpacks this shadowy, but metastasizing problem confronting our security--both for individuals and nations. The uncomfortable truth is that we do not take cybersecurity seriously enough. Strong regulations on automotive safety or guidelines for the airline industry are commonplace, but when it comes to the internet, it might as well be the Wild West. Standards of securing our computers and other internet-connected technology are diverse, but just like the rules of the road meant to protect both individual drivers and everyone else driving alongside them, weak cybersecurity on the computers and internet systems near us put everyone at risk. Lucas sounds a compelling and necessary alarm on behalf of cybersecurity and prescribes immediate and bold solutions to this grave threat.

    This book demonstrates how the notation and process complement one another, using UML models to illustrate the new process in action. It describes the constructs such as use cases, actors, and more.
