Philosophical and ethical discussions of warfare are often tied to emerging technologies and techniques. Today we are presented with what many believe is a radical shift in the nature of war-the realization of conflict in the cyber-realm, the so-called "fifth domain " of warfare. Does an aggressive act in the cyber-realm constitute an act of war? If so, what rules should govern such warfare? Are the standard theories of just war capable of analyzing and assessing this mode of conflict? These changing circumstances present us with a series of questions demanding serious attention. Is there such a thing as cyberwarfare? How do the existing rules of engagement and theories from the just war tradition apply to cyberwarfare? How should we assess a cyber-attack conducted by a state agency against private enterprise and vice versa? Furthermore, how should actors behave in the cyber-realm? Are there ethical norms that can be applied to the cyber-realm? Are the classic just war constraints of non-combatant immunity and proportionality possible in this realm? Especially given the idea that events that are constrained within the cyber-realm do not directly physically harm anyone, what do traditional ethics of war conventions say about this new space? These questions strike at the very center of contemporary intellectual discussion over the ethics of war. In twelve original essays, plus a foreword from John Arquilla and an introduction, Binary Bullets: The Ethics of Cyberwarfare, engages these questions head on with contributions from the top scholars working in this field today.

The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold’s companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18:  Let’s Build a Clock! Chapter 21:  The Arithmetic Logic Unit Chapter 22:  Registers and Busses Chapter 23:  CPU Control Signals Chapter 24:  Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.
