Death by Video Game: Danger, Pleasure, and Obsession on the Virtual Frontline
by Simon Parkin"The finest book on video games yet. Simon Parkin thinks like a critic, conjures like a novelist, and writes like an artist at the height of his powers--which, in fact, he is." --Tom Bissell, author of Extra Lives: Why Video Games MatterOn January 31, 2012, a twenty-three-year-old student was found dead at his keyboard in an internet café while the video game he had been playing for three days straight continued to flash on the screen in front of him. Trying to reconstruct what had happened that night, investigative journalist Simon Parkin would discover that there have been numerous other incidents of "death by video game." And so begins a journey that takes Parkin around the world in search of answers: What is it about video games that inspires such tremendous acts of endurance and obsession? Why do we so thoroughly lose our sense of time and reality within this medium? How in the world can people play them . . . to death?In Death by Video Game, Parkin examines the medical evidence and talks to the experts to determine what may be happening, and introduces us to the players and game developers at the frontline of virtual extremism: the New York surgeon attempting to break the Donkey Kong world record . . . the Minecraft player three years into an epic journey toward the edge of the game's vast virtual world . . . the German hacker who risked prison to discover the secrets behind Half-Life 2 . . .Riveting and wildly entertaining, Death by Video Game will change the way we think about our virtual playgrounds as it investigates what it is about them that often proves compelling, comforting, and irresistible to the human mind--except for when it's not.From the Hardcover edition.
The Death of the Internet
by Markus JakobssonFraud poses a significant threat to the Internet. 1.5% of all online advertisements attempt to spread malware. This lowers the willingness to view or handle advertisements, which will severely affect the structure of the web and its viability. It may also destabilize online commerce. In addition, the Internet is increasingly becoming a weapon for political targets by malicious organizations and governments. This book will examine these and related topics, such as smart phone based web security. This book describes the basic threats to the Internet (loss of trust, loss of advertising revenue, loss of security) and how they are related. It also discusses the primary countermeasures and how to implement them.
The Death of Web 2.0: Ethics, Connectivity and Recognition in the Twenty-First Century
by Greg SinghWith all our contemporary connectivity, are we really connected? What does the nature of connectivity tell us about interpersonal and community relationships? What ethical concerns are raised through an always-on culture? Communication in today’s world is characterised by a condition of persistent, semi-permanent connectivity, which seems to bring us closer together, but which can also be profoundly alienating. The Death of Web 2.0 takes a retrospective look at a moment in recent media history that has had, and will continue to have, a lasting impact upon the predominant attitude towards cultures of connectivity. Greg Singh draws from a range of approaches, intellectual traditions and scholarly disciplines to engage key questions underpinning the contemporary communications media ecosystem. Bringing together influences from communitarian ethics, recognition theory and relational and depth psychology, Singh synthesises key approaches to produce a critical inquiry that projects the tensions at the heart of connectivity as a principle of Web 2.0. He argues that Web 2.0 is a cultural moment that is truly over, and that what is popularly described as 'Web 2.0' is an altogether different set of principles and practices. The Death of Web 2.0 recognises the consequences of our 'always-on' culture, where judgments are made quickly and where impacts can be far-reaching, affecting our relationships, wellbeing, mental health and the health of our communities, and it concludes by asking what an ethics of connectivity would look like. This unique interdisciplinary work will be essential reading for academics and students of Jungian and post-Jungian studies, media and cultural studies and psychosocial studies as well as anyone interested in the social implications of new media.
Debate Dynamics: How Controversy Improves Our Beliefs
by Gregor BetzIs critical argumentation an effective way to overcome disagreement? And does the exchange of arguments bring opponents in a controversy closer to the truth? This study provides a new perspective on these pivotal questions. By means of multi-agent simulations, it investigates the truth and consensus-conduciveness of controversial debates. The book brings together research in formal epistemology and argumentation theory. Aside from its consequences for discursive practice, the work may have important implications for philosophy of science and the way we construe scientific rationality as well.

The Debates Shaping Spectrum Policy
by Martin SimsWhat debates have caused spectrum policy to change course and which will determine its future direction? This book examines these issues through a series of chapters from a range of notable experts. The backdrop is a period of turbulent change in what was once a quiet backwater. The past quarter century has seen wireless connectivity go from nice-to-have luxury to the cornerstone of success as nations battle for leadership of the digital economy. The change has been reflected in the crucial role now played by market's mechanisms in a field once dominated by administrative decisions. Spectrum policy’s goals have moved far beyond the efficient use of the airwaves to include encouraging economic development, investment, innovation, sustainability and digital inclusivity. Are historic procedures still appropriate in the face of this multiplicity of demands? Are market mechanisms like auctions still the best way to deliver what has become essential infrastructure? Does the process of international coordination need to change? Is spectrum policy’s effectiveness limited by the power of global economic forces? Can it reduce rather than add to global warming? Where does 6G and AI fit in? Is public perception the new spectrum policy battle ground? These are all issues examined in The Debates Shaping Spectrum Policy.
Debating Immigrants and Refugees in Central Europe: Politicising and Framing Newcomers in the Media and Political Arenas (Routledge/UACES Contemporary European Studies)
by Jan KovářThis book investigates the politicisation and framing of immigration in the media and political arena in Central Europe, examining two countries - Czechia and Slovakia - in the period surrounding the “European migrant crisis”. Following years of immigration being practically invisible as an issue in the socio-political debates in most Central and Eastern European countries, it became a key concern because of the crisis. Analyzing news media items and plenary speeches, this book reveals how securitisation eclipses humanitarian considerations, dominating the discourse around immigration and that media and politicians are the two most important intermediaries from which citizens take cues on issues they rarely experience directly themselves. Finally, it also shows how the media and political arena portray immigration differently based on the origin, religious background, and legal status of immigrants. This book will be of key interest to scholars and students of migration studies, global governance, international organisations, security studies, and media studies, as well as more broadly for public law, comparative politics and East/Central European politics.

Debugging at the Electronic System Level
by Frank Rogin Rolf DrechslerDebugging becomes more and more the bottleneck to chip design productivity, especially while developing modern complex integrated circuits and systems at the Electronic System Level (ESL). Today, debugging is still an unsystematic and lengthy process. Here, a simple reporting of a failure is not enough, anymore. Rather, it becomes more and more important not only to find many errors early during development but also to provide efficient methods for their isolation. In Debugging at the Electronic System Level the state-of-the-art of modeling and verification of ESL designs is reviewed. There, a particular focus is taken onto SystemC. Then, a reasoning hierarchy is introduced. The hierarchy combines well-known debugging techniques with whole new techniques to improve the verification efficiency at ESL. The proposed systematic debugging approach is supported amongst others by static code analysis, debug patterns, dynamic program slicing, design visualization, property generation, and automatic failure isolation. All techniques were empirically evaluated using real-world industrial designs. Summarized, the introduced approach enables a systematic search for errors in ESL designs. Here, the debugging techniques improve and accelerate error detection, observation, and isolation as well as design understanding.
Debugging Game History: A Critical Lexicon
by Raiford Guins Henry LowoodEven as the field of game studies has flourished, critical historical studies of games have lagged behind other areas of research. Histories have generally been fact-by-fact chronicles; fundamental terms of game design and development, technology, and play have rarely been examined in the context of their historical, etymological, and conceptual underpinnings. This volume attempts to "debug" the flawed historiography of video games. It offers original essays on key concepts in game studies, arranged as in a lexicon -- from "Amusement Arcade" to "Embodiment" and "Game Art" to "Simulation" and "World Building." Written by scholars and practitioners from a variety of disciplines, including game development, curatorship, media archaeology, cultural studies, and technology studies, the essays offer a series of distinctive critical "takes" on historical topics. The majority of essays look at game history from the outside in; some take deep dives into the histories of play and simulation to provide context for the development of electronic and digital games; others take on such technological components of games as code and audio. Not all essays are history or historical etymology -- there is an analysis of game design, and a discussion of intellectual property -- but they nonetheless raise questions for historians to consider. Taken together, the essays offer a foundation for the emerging study of game history. ContributorsMarcelo Aranda, Brooke Belisle, Caetlin Benson-Allott, Stephanie Boluk, Jennifer deWinter, J. P.

Debugging Systems-on-Chip
by Bart Vermeulen Kees GoossensThis book describes an approach and supporting infrastructure to facilitate debugging the silicon implementation of a System-on-Chip (SOC), allowing its associated product to be introduced into the market more quickly Readers learn step-by-step the key requirements for debugging a modern, silicon SOC implementation, nine factors that complicate this debugging task, and a new debug approach that addresses these requirements and complicating factors The authors' novel communication-centric, scan-based, abstraction-based, run/stop-based (CSAR) debug approach is discussed in detail, showing how it helps to meet debug requirements and address the nine, previously identified factors that complicate debugging silicon implementations of SOCs. The authors also derive the debug infrastructure requirements to support debugging of a silicon implementation of an SOC with their CSAR debug approach. This debug infrastructure consists of a generic on-chip debug architecture, a configurable automated design-for-debug flow to be used during the design of an SOC, and customizable off-chip debugger software. Coverage includes an evaluation of the efficiency and effectiveness of the CSAR approach and its supporting infrastructure, using six industrial SOCs and an illustrative, example SOC model The authors also quantify the hardware cost and design effort to support their approach.
Debugging Teams: Better Productivity through Collaboration
by Ben Collins-Sussman Brian W. FitzpatrickIn the course of their 20+-year engineering careers, authors Brian Fitzpatrick and Ben Collins-Sussman have picked up a treasure trove of wisdom and anecdotes about how successful teams work together. Their conclusion? Even among people who have spent decades learning the technical side of their jobs, most haven't really focused on the human component. Learning to collaborate is just as important to success. If you invest in the "soft skills" of your job, you can have a much greater impact for the same amount of effort. The authors share their insights on how to lead a team effectively, navigate an organization, and build a healthy relationship with the users of your software. This is valuable information from two respected software engineers whose popular series of talks--including "Working with Poisonous People"--has attracted hundreds of thousands of followers.

Decent Work: Concept, Theory and Measurement
by Nausheen Nizami Narayan PrasadThis book introduces readers to the concept and theories of decent work and provides a framework for measuring it at the micro, meso and macro level in a given country. Further, it addresses the importance of measuring decent work in today's world and in connection with the different challenges countries face depending on their respective stage of development. The essence of the book lies in highlighting the practical applications of decent work in terms of its ability to deliver empirical measurements of qualitative and subjective phenomena with a mixed-methods approach combining tools and techniques from economics and statistics. Moreover, as the applicability of decent work is not confined to the IT industry and formal sectors of the economy, the book also provides useful guidelines on how further empirical studies can be undertaken to measure decent work in non-IT industries. As such, the book offers a rich compilation of empirical and theoretical contributions on decent work designed to not only enrich readers' understanding, but also promote awareness of the practical relevance and technical aspects of the subject matter.
Decentralised Internet of Things: A Blockchain Perspective (Studies in Big Data #71)
by Mohammad Ayoub Khan Mohammad Tabrez Quasim Fahad Algarni Abdullah AlharthiThis book presents practical as well as conceptual insights into the latest trends, tools, techniques and methodologies of blockchains for the Internet of Things. The decentralised Internet of Things (IoT) not only reduces infrastructure costs, but also provides a standardised peer-to-peer communication model for billions of transactions. However, there are significant security challenges associated with peer-to-peer communication. The decentralised concept of blockchain technology ensures transparent interactions between different parties, which are more secure and reliable thanks to distributed ledger and proof-of-work consensus algorithms. Blockchains allow trustless, peer-to-peer communication and have already proven their worth in the world of financial services. The blockchain can be implanted in IoT systems to deal with the issues of scale, trustworthiness and decentralisation, allowing billions of devices to share the same network without the need for additional resources. This book discusses the latest tools and methodology and concepts in the decentralised Internet of Things. Each chapter presents an in-depth investigation of the potential of blockchains in the Internet of Things, addressing the state-of-the-art in and future perspectives of the decentralised Internet of Things. Further, industry experts, researchers and academicians share their ideas and experiences relating to frontier technologies, breakthrough and innovative solutions and applications.

Decentralized Neural Control: Application to Robotics
by Ramon Garcia-Hernandez Michel Lopez-Franco Edgar N. Sanchez Alma Y. Alanis Jose A. Ruz-HernandezThis book provides a decentralized approach for the identification and control of robotics systems. It also presents recent research in decentralized neural control and includes applications to robotics. Decentralized control is free from difficulties due to complexity in design, debugging, data gathering and storage requirements, making it preferable for interconnected systems. Furthermore, as opposed to the centralized approach, it can be implemented with parallel processors. This approach deals with four decentralized control schemes, which are able to identify the robot dynamics. The training of each neural network is performed on-line using an extended Kalman filter (EKF). The first indirect decentralized control scheme applies the discrete-time block control approach, to formulate a nonlinear sliding manifold. The second direct decentralized neural control scheme is based on the backstepping technique, approximated by a high order neural network. The third control scheme applies a decentralized neural inverse optimal control for stabilization. The fourth decentralized neural inverse optimal control is designed for trajectory tracking. This comprehensive work on decentralized control of robot manipulators and mobile robots is intended for professors, students and professionals wanting to understand and apply advanced knowledge in their field of work.
