In 2009, BlackBerry controlled half of the smartphone market. Today that number is one percent. What went so wrong?

Losing the Signal is a riveting story of a company that toppled global giants before succumbing to the ruthlessly competitive forces of Silicon Valley. This is not a conventional tale of modern business failure by fraud and greed. The rise and fall of BlackBerry reveals the dangerous speed at which innovators race along the information superhighway.

With unprecedented access to key players, senior executives, directors and competitors, Losing the Signal unveils the remarkable rise of a company that started above a bagel store in Ontario. At the heart of the story is an unlikely partnership between a visionary engineer, Mike Lazaridis, and an abrasive Harvard Business school grad, Jim Balsillie. Together, they engineered a pioneering pocket email device that became the tool of choice for presidents and CEOs. The partnership enjoyed only a brief moment on top of the world, however. At the very moment BlackBerry was ranked the world's fastest growing company internal feuds and chaotic growth crippled the company as it faced its gravest test: Apple and Google's entry in to mobile phones.

Expertly told by acclaimed journalists, Jacquie McNish and Sean Silcoff, this is an entertaining, whirlwind narrative that goes behind the scenes to reveal one of the most compelling business stories of the new century.

An extraordinary exploration of how technology can empower social and political organizers

For the first time in history, the tools for cooperating on a global scale are not solely in the hands of governments or institutions. The spread of the internet and mobile phones are changing how people come together and get things done—and sparking a revolution that, as Clay Shirky shows, is changing what we do, how we do it, and even who we are. Here, we encounter a whoman who loses her phone and recruits an army of volunteers to get it back from the person who stole it. A dissatisfied airline passenger who spawns a national movement by taking her case to the web. And a handful of kids in Belarus who create a political protest that the state is powerless to stop. Here Comes Everybody is a revelatory examination of how the wildfirelike spread of new forms of social interaction enabled by technology is changing the way humans form groups and exist within them. A revolution in social organization has commenced, and Clay Shirky is its brilliant chronicler.

"Drawing from anthropology, economic theory and keen observation, [Shirky] makes a strong case that new communication tools are making once-impossible forms of group action possible . . . [an] extraordinarily perceptive new book." -Minneapolis Star Tribune

"Mr. Shirky writes cleanly and convincingly about the intersection of technological innovation and social change." -New York Observer

Testing applications for mobile phones is difficult, time-consuming, and hard to do effectively. Many people have limited their testing efforts to hands-on testing of an application on a few physical handsets, and they have to repeat the process every time a new version of the software is ready to test. They may miss many of the permutations of real-world use, and as a consequence their users are left with the unpleasant mess of a failing application on their phone. Test automation can help to increase the range and scope of testing, while reducing the overhead of manual testing of each version of the software. However automation is not a panacea, particularly for mobile applications, so we need to pick our test automation challenges wisely. This book is intended to help software and test engineers pick appropriately to achieve more; and as a consequence deliver better quality, working software to users. This Synthesis lecture provides practical advice based on direct experience of using software test automation to help improve the testing of a wide range of mobile phone applications, including the latest AJAX applications. The focus is on applications that rely on a wireless network connection to a remote server, however the principles may apply to other related fields and applications. We start by explaining terms and some of the key challenges involved in testing smartphone applications. Subsequent chapters describe a type of application e.g. markup, AJAX, Client, followed by a related chapter on how to test each of these applications. Common test automation techniques are covered in a separate chapter, and finally there is a brief chapter on when to test manually. The book also contains numerous pointers and links to further material to help you to improve your testing using automation appropriately. Table of Contents: Introduction / Markup Languages / Testing Techniques for Markup Applications / AJAX Mobile Applications / Testing Mobile AJAX Applications / Client Applications / Testing Techniques for Client Applications / Common Techniques / When to Test Manually / Future Work / Appendix A: Links and References / Appendix B: Data Connectivity / Appendix C: Configuring Your Machine

With an approach that balances the introduction of new models and new coding techniques, readers are guided through Shannon's point-to-point information theory, single-hop networks, multihop networks, and extensions to distributed computing, secrecy, wireless communication, and networking. Elementary mathematical tools and techniques are used throughout, requiring only basic knowledge of probability, whilst unified proofs of coding theorems are based on a few simple lemmas, making the text accessible to newcomers. Key topics covered include successive cancellation and superposition coding, MIMO wireless communication, network coding, and cooperative relaying. Also covered are feedback and interactive communication, capacity approximations and scaling laws, and asynchronous and random access channels. This book is ideal for use in the classroom, for self-study, and as a reference for researchers and engineers in industry and academia.

Each laboratory project in the back of the book presents a complete simulation and reflects the same progression of topics found in the main text. The projects describe the overall goals of the experiment, discuss the general network topology, and give a high-level description of the system configuration required to complete the simulation.

Discover the Complex Functionality Available in OPNET
By providing an in-depth look at the rich features of OPNET software, this guide is an invaluable reference for IT professionals and researchers who need to create simulation models. The book also helps newcomers understand OPNET by organizing the material in a logical manner that corresponds to the protocol layers in a network.

Invented more than a hundred years ago by Alexander Graham Bell, the technology of free-space optical communications, or lasercom, has finally reached the level of maturity required to meet a growing demand for operational multi-giga-bit-per-second data rate systems communicating to and from aircrafts and satellites. Putting the emphasis on near-earth links, including air, LEO, MEO, and GEO orbits, Near-Earth Laser Communications presents a summary of important free-space laser communication subsystem challenges and discusses potential ways to overcome them.

This comprehensive reference provides up-to-date information on component and subsystem technologies, fundamental limitations, and approaches to reach those limits. It covers basic concepts and state-of-the-art technologies, emphasizing device technology, implementation techniques, and system trades. The authors discuss hardware technologies and their applications, and also explore ongoing research activities and those planned for the near future.

The analytical aspects of laser communication have been covered to a great extent in several books. However, a detailed approach to system design and development, including trades on subsystem choices and implications of the hardware selection for satellite and aircraft telecommunications, is missing. Highlighting key design variations and critical differences between them, this book distills decades’ worth of experience into a practical resource on hardware technologies.

An eye-opening account of how the hidden rise of personalization on the Internet is controlling-and limiting-the information we consume.

In December 2009, Google began customizing its search results for each user. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years-the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.

Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook-the primary news source for an increasing number of Americans-prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like The Washington Post devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.

In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs-and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.

While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far- reaching trend on the Internet and shows how we can- and must-change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.

The shift from orality to literacy that began with the invention of the phonetic alphabet, and which went into high-gear with Gutenberg’s printing press more than 500 years ago, helped make the modern world. Some commentators have argued that this shift from orality to literacy marked a much broader, cultural shift of cataclysmic proportions. Today, with everything from e-mail to blogs, iPods and podcasts, through Google, Yahoo, eBay, and with cutting-edge smart phones, we find ourselves developing relationships with these newest communication tools that aren’t simply allowing us to communicate faster, farther and with more ease than ever before. We aren’t just moving around ideas, data, and information at unimaginable speed and scale. Our interminglings and fusions with digital communication technologies are also altering both individual and group consciousness in fundamental ways – how we form and sustain relationships, how we think and perceive, what it means to see and to feel. We are remaking human identity once more, and manufacturing a new kind of culture along the way. The processes bound up in our digination may well be consequential to the trajectory of human evolution.

That time-honored trope: the notion that technology is not the problem, rather, it’s how people use technology that’s the problem is shown to be wanting. Highlighting Marshall McLuhan’s “tetrads” or laws of media as a primary tool of analysis, R.C. MacDougall argues in line with other media ecologists that it’s not so much how we use certain tools that matters, it’s that we use them. More than any other technological form perhaps, communication technologies play particularly powerful and systemic roles in our culture, or any culture for that matter. Late adopters and even abstainers are not exempt from the psychological, social and cultural effects (and side-effects) of modern digital communication technology. While there are certainly varying degrees of immersion –that is to say, while some of us live in the high-rise downtown district, some at the city limits, and still others out in the proverbial “woods”– we all live in Digination today.

In Reinventing Discovery, Michael Nielsen argues that we are living at the dawn of the most dramatic change in science in more than 300 years. This change is being driven by powerful new cognitive tools, enabled by the internet, which are greatly accelerating scientific discovery. There are many books about how the internet is changing business or the workplace or government. But this is the first book about something much more fundamental: how the internet is transforming the nature of our collective intelligence and how we understand the world.

Reinventing Discovery tells the exciting story of an unprecedented new era of networked science. We learn, for example, how mathematicians in the Polymath Project are spontaneously coming together to collaborate online, tackling and rapidly demolishing previously unsolved problems. We learn how 250,000 amateur astronomers are working together in a project called Galaxy Zoo to understand the large-scale structure of the Universe, and how they are making astonishing discoveries, including an entirely new kind of galaxy. These efforts are just a small part of the larger story told in this book--the story of how scientists are using the internet to dramatically expand our problem-solving ability and increase our combined brainpower.

This is a book for anyone who wants to understand how the online world is revolutionizing scientific discovery today--and why the revolution is just beginning.

Spreadable Media maps fundamental changes taking place in our contemporary media environment, a space where corporations no longer tightly control media distribution and many of us are directly involved in the circulation of content. It contrasts “stickiness”—aggregating attention in centralized places—with “spreadability”—dispersing content widely through both formal and informal networks, some approved, many unauthorized. Stickiness has been the measure of success in the broadcast era (and has been carried over to the online world), but “spreadability” describes the ways content travels through social media.   Following up on the hugely influential Convergence Culture: Where Old and New Media Collide, this book challenges some of the prevailing metaphors and frameworks used to describe contemporary media, from biological metaphors like “memes” and “viral” to the concept of “Web 2.0” and the popular notion of “influencers.” Spreadable Media examines the nature of audience engagement,the environment of participation, the way appraisal creates value, and the transnational flows at the heart of these phenomena. It delineates the elements that make content more spreadable and highlights emerging media business models built for a world of participatory circulation. The book also explores the internal tensions companies face as they adapt to the new communication reality and argues for the need to shift from “hearing” to “listening” in corporate culture.   Drawing on examples from film, music, games, comics, television, transmedia storytelling, advertising, and public relations industries, among others—from both the U.S. and around the world—the authors illustrate the contours of our current media environment. They highlight the vexing questions content creators must tackle and the responsibilities we all face as citizens in a world where many of us regularly circulate media content. Written for any and all of us who actively create and share media content, Spreadable Media provides a clear understanding of how people are spreading ideas and the implications these activities have for business, politics, and everyday life.

The explosive growth of e-commerce and online environments has made the issue of information search and selection increasingly serious; users are overloaded by options to consider and they may not have the time or knowledge to personally evaluate these options. Recommender systems have proven to be a valuable way for online users to cope with the information overload and have become one of the most powerful and popular tools in electronic commerce. Correspondingly, various techniques for recommendation generation have been proposed. During the last decade, many of them have also been successfully deployed in commercial environments.

Recommender Systems Handbook, an edited volume, is a multi-disciplinary effort that involves world-wide experts from diverse fields, such as artificial intelligence, human computer interaction, information technology, data mining, statistics, adaptive user interfaces, decision support systems, marketing, and consumer behavior. Theoreticians and practitioners from these fields continually seek techniques for more efficient, cost-effective and accurate recommender systems. This handbook aims to impose a degree of order on this diversity, by presenting a coherent and unified repository of recommender systems’ major concepts, theories, methodologies, trends, challenges and applications. Extensive artificial applications, a variety of real-world applications, and detailed case studies are included.

Recommender Systems Handbook illustrates how this technology can support the user in decision-making, planning and purchasing processes. It works for well known corporations such as Amazon, Google, Microsoft and AT&T. This handbook is suitable for researchers and advanced-level students in computer science as a reference.

A Brief Journey through “Wireless Mesh Networks: Architectures and Protocols” Ekram Hossain, University of Manitoba, Winnipeg, Canada Kin Leung, Imperial College, London, United Kingdom Introduction Wireless mesh networking has emerged as a promising design paradigm for next gen eration wireless networks. Wireless mesh networks (WMNs) consist of mesh clients and mesh routers, where the mesh routers form a wireless infrastructure/backbone and interwork with the wired networks to provide multihop wireless Internet con nectivity to the mesh clients. Wireless mesh networking has emerged as one of the most promising concept for self organizing and auto con?gurable wireless network ing to provide adaptive and ?exible wireless Internet connectivity to mobile users. This concept can be used for different wireless access technologies such as IEEE 802. 11, 802. 15, 802. 16 based wireless local area network (WLAN), wireless per sonal area network (WPAN), and wireless metropolitan area network (WMAN) tech nologies, respectively. Potential application scenarios for wireless mesh networks in clude backhaul support for cellular networks, home networks, enterprise networks, community networks, and intelligent transport system networks. Development of wireless mesh networking technology has to deal with challenging architecture and protocol design issues, and there is an increasing interest on this technology among the researchers in both academia and industry. There are many on going research projects in different universities and industrial research labs. Also, many startup com panies are building mesh networking platforms based on off the shelf wireless access technologies and developing demanding applications and services.
