Capitalization is about $120 billion World recognition The world's largest economies – India and Japan – recognized Bitcoin as the official currency. The US authorities recognized cryptocurrency as the asset. And this is just the beginning.

    He was a normal kid...On February 7, 2000, Yahoo.com was the first victim of the biggest distributed denial-of-service attack ever to hit the Internet. On May 8th, Buy.com was battling a massive denial-of-service attack. Later that afternoon, eBay.com also reported significant outages of service, as did Amazon.com. Then CNN's global online news operation started to grind to a crawl. By the following day, Datek and E-Trade entered crisis mode...all thanks to an ordinary fourteen-year-old kid.Friends and neighbors were shocked to learn that the skinny, dark-haired, boy next door who loved playing basketball--almost as much as he loved computers--would cause millions of dollars worth of damage on the Internet and capture the attention of the online world--and the federal government. He was known online as Mafiaboy and, to the FBI, as the most notorious teenage hacker of all time. He did it all from his bedroom PC. And he's not alone.Computer hacking and Web site defacement has become a national pastime for America's teenagers, and according to the stories you'll read about in The Hacker Diaries--it is only the beginning. But who exactly are these kids and what motivates a hacker to strike? Why do average teenagers get involved in hacking in the first place? This compelling and revealing book sets out to answer these questions--and some of the answers will surprise you. Through fascinating interviews with FBI agents, criminal psychologists, law-enforcement officials--as well as current and former hackers--you'll get a glimpse inside the mind of today's teenage hacker. Learn how they think, find out what it was like for them growing up, and understand the internal and external pressures that pushed them deeper and deeper into the hacker underground. Every hacker has a life and story of his or her own. One teenager's insatiable curiosity as to how the family's VCR worked was enough to trigger a career of cracking into computer systems. This is a remarkable story of technological wizardry, creativity, dedication, youthful angst, frustration and disconnection from society, boredom, anger, and jail time. Teenage hackers are not all indifferent punks. They're just like every other kid and some of them probably live in your neighborhood. They're there. All you have to do is look.

    Sundar Pichai’s appointment was hardly an unexpected one. Pichai is a man known as much for his veritable Midas touch with every product he has developed or led for Google – Chrome, Chrome OS and Android, to name just a few – as for his superlative people skills and open-minded approach to innovation. Yet, the company’s decision to restructure its product lines and appoint Pichai as the head of a leaner, more focused Google, has raised inevitable questions: • What does Pichai’s role augur for the future of the tech giant? • Will Google consolidate its position for existing products or will they focus on creating new ones? • And will Pichai transform the organization that Schmidt, Page and Brin created and led, or confirm the belief of a minority of naysayers that he is not yet ready for this daunting role? Pichai: The Future of Google provides answers to these questions while throwing light on Sundar Pichai’s childhood and education; his entry into the tech world and quick rise up the ranks in Google; and his key contributions as a leader and tech-guru to Google’s most successful properties. Timely and insightful, this book offers a rare glimpse into the fascinating ecosystem of a path-breaking company and shows us what it takes to be a dynamic leader in the 21st century.

    Billions of interconnected devices will be monitoring the environment, transportation systems, factories, farms, forests, utilities, soil and weather conditions, oceans and resources Many of these sensors and actuators will be networked into autonomous sets, with much of the information being exchanged machine-to-machine directly and without human involvement. Machine-to-machine communications are typically terse. Most sensors and actuators will report or act upon small pieces of information - chirps. Burdening these devices with current network protocol stacks is inefficient, unnecessary and unduly increases their cost of ownership. This must change. The architecture of the Internet of Things will entail a widely distributed topology incorporating simpler chirp protocols towards at the edges of the network. Rethinking the Internet of Things describes reasons why we must rethink current approaches to the Internet of Things. Appropriate architectures that will coexist with existing networking protocols are described in detail. An architecture comprised of integrator functions, propagator nodes, and end devices, along with their interactions, is explored. What you'll learn Teaches the difference between the "normal" Internet and the Internet of Things, Describes a new architecture and its components in the "chirp" context. Explains the shortcomings of IP for IoT. Describes the anatomy of the IoT. Re-frames key ideas such as reliability. Describes how to build the IoT Who this book is forThought leaders, executives, architectural, standards and development leaders in the evolving IoT industry

    Cooper details many of these meta functions to explain his central thesis: programmers need to seriously re-evaluate the many user-hostile concepts deeply embedded within the software development process. Rather than provide users with a straightforward set of options, programmers often pile on the bells and whistles and ignore or de-prioritise lingering bugs. For the average user, increased functionality is a great burden, adding to the recurrent chorus that plays: "computers are hard, mysterious, unwieldy things." (An average user, Cooper asserts, who doesn't think that way or who has memorised all the esoteric commands and now lords it over others, has simply been desensitised by too many years of badly designed software.) Cooper's writing style is often overblown, with a pantheon of cutesy terminology (i.e. "dancing bearware") and insider back-patting. (When presenting software to Bill Gates, he reports that Gates replied: "How did you do that?" to which he writes: "I love stumping Bill!") More seriously, he is also unable to see beyond software development's importance--a sin he accuses programmers of throughout the book. Even with that in mind, the central questions Cooper asks are too important to ignore: Are we making users happier? Are we improving the process by which they get work done? Are we making their work hours more effective? Cooper looks to programmers, business managers and what he calls "interaction designers" to question current assumptions and mindsets. Plainly, he asserts that the goal of computer usage should be "not to make anyone feel stupid." Our distance from that goal reinforces the need to rethink entrenched priorities in software planning. -- Jennifer Buckendorff, Amazon.com

    We depend on it for everything we do. We have reengineered our business, governance, and social relations around a planetary network unlike any before it. But there are dangers looming, and malign forces are threatening to transform this extraordinary domain.In Black Code, Ronald J. Deibert, a leading expert on digital technology, security, and human rights, lifts the lid on cyberspace and shows what’s at stake for Internet users and citizens. As cyberspace develops in unprecedented ways, powerful agents are scrambling for control. Predatory cyber criminal gangs such as Koobface have made social media their stalking ground. The discovery of Stuxnet, a computer worm reportedly developed by Israel and the United States and aimed at Iran’s nuclear facilities, showed that state cyberwar is now a very real possibility. Governments and corporations are in collusion and are setting the rules of the road behind closed doors.This is not the way it was supposed to be. The Internet’s original promise of a global commons of shared knowledge and communications is now under threat. Drawing on the first-hand experiences of one of the most important protagonists in the battle — the Citizen Lab and its global network of frontline researchers, who have spent more than a decade cracking cyber espionage rings and uncovering attacks on citizens and NGOs worldwide — Black Code takes readers on a fascinating journey into the battle for cyberspace. Thought-provoking, compelling, and sometimes frightening, it is a wakeup call to citizens who have come to take the Internet for granted. Cyberspace is ours, it is what we make of it, Deibert argues, and we need to act now before it slips through our grasp.
