Raising a Screen-Smart Kid: Embrace the Good and Avoid the Bad in the Digital Age
by Julianna MinerFor parents who didn't grow up with smartphones but can't let go of them now, expert advice on raising kids in our constantly connected worldMost kids get their first smartphone at the same time that they're experiencing major developmental changes. Making mistakes has always been a part of growing up, but how do parents help their kids navigate childhood and adolescence at a time when social media has the potential to magnify the consequences of those mistakes? Rather than spend all their time worrying about the worst-case scenario, readers get a bigger-picture understanding of their kids' digital landscape. Drawing on research and interviews with educators, psychologists, and kids themselves, Raising a Screen-Smart Kid offers practical advice on how parents can help their kids avoid the pitfalls and reap the benefits of the digital age by: * using social media to enhance connection with friends and family, instead of following strangers and celebrities, which is a predictor of loneliness and depression * finding online support and community for conditions such as depression and eating disorders, while avoiding potential triggers such as #Thinspiration Pinterest boards * learning and developing life skills through technology--for example, by problem-solving in online games--while avoiding inappropriate contentWritten by a public health expert and the creator of the popular blog Rants from Mommyland, this book shows parents how to help their kids navigate friendships, bullying, dating, self-esteem, and more online.
Rainbows End
by Vernor VingeFour time Hugo Award winner Vernor Vinge has taken readers to the depths of space and into the far future in his bestselling novels A Fire Upon the Deep and A Deepness in the Sky. Now, he has written a science-fiction thriller set in a place and time as exciting and strange as any far-future world: San Diego, California, 2025.<P><P> Robert Gu is a recovering Alzheimer's patient. The world that he remembers was much as we know it today. Now, as he regains his faculties through a cure developed during the years of his near-fatal decline, he discovers that the world has changed and so has his place in it. He was a world-renowned poet. Now he is seventy-five years old, though by a medical miracle he looks much younger, and he's starting over, for the first time unsure of his poetic gifts. Living with his son's family, he has no choice but to learn how to cope with a new information age in which the virtual and the real are a seamless continuum, layers of reality built on digital views seen by a single person or millions, depending on your choice. But the consensus reality of the digital world is available only if, like his thirteen-year-old granddaughter Miri, you know how to wear your wireless access -- through nodes designed into smart clothes -- and to see the digital context -- through smart contact lenses.<P> With knowledge comes risk. When Robert begins to re-train at Fairmont High, learning with other older people what is second nature to Miri and other teens at school, he unwittingly becomes part of a wide-ranging conspiracy to use technology as a tool for world domination.<P> In a world where every computer chip has Homeland Security built-in, this conspiracy is something that baffles even the most sophisticated security analysts, including Robert's son and daughter-in law, two top people in the U.S. military. And even Miri, in her attempts to protect her grandfather, may be entangled in the plot.<P> As Robert becomes more deeply involved in conspiracy, he is shocked to learn of a radical change planned for the UCSD Geisel Library; all the books there, and worldwide, would cease to physically exist. He and his fellow re-trainees feel compelled to join protests against the change. With forces around the world converging on San Diego, both the conspiracy and the protest climax in a spectacular moment as unique and satisfying as it is unexpected. This is science fiction at its very best, by a master storyteller at his peak.<P> Hugo Award winner.

Rail Transport—Systems Approach
by Aleksander SładkowskiThis book shows how the systems approach is employed by scientists in various countries to solve specific problems concerning railway transport. In particular, the book describes the experiences of scientists from Romania, Germany, the Czech Republic, the UK, Russia, Ukraine, Lithuania and Poland. For many of these countries there is a problem with the historical differences between the railways. In particular, there are railways with different rail gauges, with different signaling and communication systems, with different energy supplies and, finally, with different political systems, which are reflected in the different approaches to the management of railway economies. The book’s content is divided into two main parts, the first of which provides a systematic analysis of individual means of providing and maintaining rail transport. In turn, the second part addresses infrastructure and management development, with particular attention to security issues. Though primarily written for professionals involved in various problems concerning railway transport, the book will also benefit manufacturers, railway technical staff, managers, and students with transport specialties, as well as a wide range of readers interested in learning more about the current state of transport in different countries.
Rage
by Matthew CostelloAn action-packed adventure based on the award-winning videogame from id Software, the creators of DOOM® and QUAKE®, Rage follows one man's fight to save the future of humanity in a ravaged, post-apocalyptic world. The asteroid Apophis has annihilated Earth, and only a small percentage of humanity's best and brightest have been saved. Buried deep below the ground in life-sustaining Arks, these chosen few are tasked with one vital mission--to restore civilization to a devastated planet hundreds of years after the impact.When Lieutenant Nick Raine emerges from his Ark, he finds a future indistinguishable from nightmare. Humankind has not been entirely destroyed on the surface world, and a primitive new society has emerged in which life is nasty, brutish, and short. Mutants and bandits prey upon the weak, and a mysterious military group known as the Authority preys upon everyone. Worst of all, a would-be tyrant seeks to impose his will upon the shattered planet. Armed with nothing more than his combat training and survival instincts, Raine must rise to meet the challenges of the wasteland.From the Trade Paperback edition.
RADIUS
by Jonathan HassellThe subject of security never strays far from the minds of IT workers, for good reason. If there is a network with even just one connection to another network, it needs to be secured. RADIUS, or Remote Authentication Dial-In User Service, is a widely deployed protocol that enables companies to authenticate, authorize and account for remote users who want access to a system or service from a central network server. Originally developed for dial-up remote access, RADIUS is now used by virtual private network (VPN) servers, wireless access points, authenticating Ethernet switches, Digital Subscriber Line (DSL) access, and other network access types. Extensible, easy to implement, supported, and actively developed, RADIUS is currently the de facto standard for remote authentication. RADIUS provides a complete, detailed guide to the underpinnings of the RADIUS protocol, with particular emphasis on the utility of user accounting. Author Jonathan Hassell draws from his extensive experience in Internet service provider operations to bring practical suggestions and advice for implementing RADIUS. He also provides instructions for using an open-source variation called FreeRADIUS. "RADIUS is an extensible protocol that enjoys the support of a wide range of vendors," says Jonathan Hassell. "Coupled with the amazing efforts of the open source development community to extend RADIUS's capabilities to other applications-Web, calling card security, physical device security, such as RSA's SecureID-RADIUS is possibly the best protocol with which to ensure only the people that need access to a resource indeed gain that access." This unique book covers RADIUS completely, from the history and theory of the architecture around which it was designed, to how the protocol and its ancillaries function on a day-to-day basis, to implementing RADIUS-based security in a variety of corporate and service provider environments. If you are an ISP owner or administrator, corporate IT professional responsible for maintaining mobile user connectivity, or a web presence provider responsible for providing multiple communications resources, you'll want this book to help you master this widely implemented but little understood protocol.

Radio Wave Propagation and Channel Modeling for Earth-Space Systems
by Athanasios G. Kanatas Athanasios D. PanagopoulosThe accurate design of earth–space systems requires a comprehensive understanding of the various propagation media and phenomena that differ depending on frequencies and types of applications. The choice of the relevant channel models is crucial in the design process and constitutes a key step in performance evaluation and testing of earth–space systems. The subject of this book is built around the two characteristic cases of satellite systems: fixed satellites and mobile satellite systems. <P><P>Radio Wave Propagation and Channel Modeling for Earth–Space Systems discusses the state of the art in channel modeling and characterization of next-generation fixed multiple-antennas and mobile satellite systems, as well as propagation phenomena and fade mitigation techniques. The frequencies of interest range from 100 MHz to 100 GHz (from VHF to W band), whereas the use of optical free-space communications is envisaged.Examining recent research advances in space-time tropospheric propagation fields and optical satellite communication channel models, the book covers land mobile multiple antennas satellite- issues and relative propagation campaigns and stratospheric channel models for various applications and frequencies. It also presents research and well-accepted satellite community results for land mobile satellite and tropospheric attenuation time-series single link and field synthesizers.The book examines aeronautical communications channel characteristics and modeling, relative radio wave propagation campaigns, and stratospheric channel model for various applications and frequencies. Propagation effects on satellite navigation systems and the corresponding models are also covered.
