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

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.

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 is a rare inside look at today’s ever-changing media landscape. The days of corporate control over media content and its distribution have been replaced by the age of what the digital media industries have called “user-generated content.” Spreadable Media maps these fundamental changes, and gives readers a comprehensive look into the rise of participatory culture, from internet memes to presidential tweets.
The authors challenge our notions of what goes “viral” and how by examining factors such as the nature of audience engagement and the environment of participation, and by contrasting the concepts of “stickiness”—aggregating attention in centralized places—with “spreadability”—dispersing content widely through both formal and informal networks. The former has often been the measure of media success in the online world, but the latter describes the actual ways content travels through social media. The book explores the internal tensions businesses face as they adapt to this new, spreadable, communication reality and argues for the need to shift from “hearing” to “listening” in corporate culture.
Now with a new afterword addressing changes in the media industry, audience participation, and political reporting, and drawing on modern examples from online activism campaigns, film, music, television, advertising, and social media—from both the U.S. and around the world—the authors illustrate the contours of our current media environment. For all of us who actively create and share 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, both on- and offline.

Kevin Mitnick's exploits as a cyber-desperado and fugitive form oneof the most exhaustive FBI manhunts in history and have spawneddozens of articles, books, films, and documentaries. Since hisrelease from federal prison, in 1998, Mitnick has turned his lifearound and established himself as one of the most sought-aftercomputer security experts worldwide. Now, in The Art of Deception,the world's most notorious hacker gives new meaning to the oldadage, "It takes a thief to catch a thief."
Focusing on the human factors involved with information security,Mitnick explains why all the firewalls and encryption protocols inthe world will never be enough to stop a savvy grifter intent onrifling a corporate database or an irate employee determined tocrash a system. With the help of many fascinating true stories ofsuccessful attacks on business and government, he illustrates justhow susceptible even the most locked-down information systems areto a slick con artist impersonating an IRS agent. Narrating fromthe points of view of both the attacker and the victims, heexplains why each attack was so successful and how it could havebeen prevented in an engaging and highly readable style reminiscentof a true-crime novel. And, perhaps most importantly, Mitnickoffers advice for preventing these types of social engineeringhacks through security protocols, training programs, and manualsthat address the human element of security.

That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right.
Thoroughly revised and expanded, Cisco IOS Cookbook, 2nd Edition, adds sections on MPLS, Security, IPv6, and IP Mobility, and presents solutions to the most common configuration problems, including:Configuring interfaces of many types, from serial to ATM and Frame RelayConfiguring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP)Configuring authenticationConfiguring other services, including DHCP and NTPSetting up backup links, and using HSRP to configure backup routersManaging the router, including SNMP and other solutionsUsing access lists to control the traffic through the router

"This is the first book about QOS that I actually enjoyedreading precisely because the authors focused on real-life QoS andnot in academic discussions about it."
Per Nihlen, IP Network Manager, NORDUnet
The new authoritative, practical guide to delivering QOSguarantees
This new benchmark in quality of service (QOS) study is writtenby two experts in the field who deal with QOS predicaments everyday. The authors not only provide a lucid understanding of moderntheory of QOS mechanisms in packet networks but how to apply themin practice. In addition, they detail the QOS management featuresfound in modern routers used by Internet Service Providers (ISPs)and large enterprise companies and networks, all in an effort toenable network managers and engineers to configure productionnetworks with a quality of service guarantee. The book's focus onaddressing network behavior ("real effects") in relation to theconfiguration of network elements (routers and switches), is bothrefreshing and insightful.
QOS-Enabled Networks contains up-to-date coverageof:QOS mechanisms in packet networks and how to apply them inpracticeQOS management features now common in modern-day routersHow network behavior is related to configuration of networkelementsLayer 2 VPN and QOSQOS in mobile LTE networks
QOS-Enabled Networks is an invaluable guide fornetworking engineers needing to provide QOS services for serviceproviders, ISPs and large enterprises, as well as for networkdesign and operations engineers.
Today's new data communication and computer interconnection systems run at unprecedented speeds, presenting new challenges not only in the design, but also in troubleshooting, test, and measurement. This book assembles contributions from practitioners at top test and measurement companies, component manufacturers,and universities. It brings together information that has never been broadly accessible before—information that was previously buried in application notes, seminar and conference presentations, short courses, and unpublished works.
Readers will gain a thorough understanding of the inner workings of digital high-speed systems, and learn how the different aspects of such systems can be tested. The editors and contributors cover key areas in test and measurement of transmitters (digital waveform and jitter analysis and bit error ratio), receivers (sensitivity, jitter tolerance, and PLL/CDR characterization), and high-speed channel characterization (in time and frequency domain). Extensive illustrations are provided throughout.
Coverage includesSignal integrity from a measurement point of view Digital waveform analysis using high bandwidth real-time and sampling (equivalent time) oscilloscopes Bit error ratio measurements for both electrical and optical links Extensive coverage on the topic of jitter in high-speed networks State-of-the-art optical sampling techniques for analysis of 100 Gbit/s + signals Receiver characterization: clock recovery, phase locked loops, jitter tolerance and transfer functions, sensitivity testing, and stressed-waveform receiver testing Channel and system characterization: TDR/T and frequency domain-based alternatives Testing and measuring PC architecture communication links: PCIexpress, SATA, and FB DIMM
