Discover never-before-told details of POW underground operations during the Vietnam War told through one airman's inspiring story of true love, honor, and courage. Air Force pilot Captain Carlyle "Smitty" Harris was shot down over Vietnam on April 4, 1965 and taken to the infamous Hoa Lo prison--nicknamed the "Hanoi Hilton." For the next eight years, Smitty and hundreds of other American POWs--including John McCain and George "Bud" Day--suffered torture, solitary confinement, and unimaginable abuse. It was there that Smitty covertly taught many other POWs the Tap Code--an old, long-unused method of communication from World War II. Using the code, they could softly tap messages of encouragement to lonely neighbors and pass along resistance policies from their leaders. The code quickly became a lifeline during their internment. It helped the prisoners boost morale, stay unified, communicate the chain of command, and prevail over a brutal enemy. Meanwhile, back home in the United States, Harris's wife, Louise, raised their three children alone, unsure of her husband's fate for seven long years. One of the first POW wives of the Vietnam War, she became a role model for other military wives by advocating for herself and her children in her husband's absence. Told through both Smitty's and Louise's voices, Tap Code shares the riveting true story of: Ingenuity under pressure Strength and dignity in the face of a frightening enemy The hope, faith, and resolve necessary to endure even the darkest circumstances Praise for Tap Code: "Tap Code is an incredible story about two American heroes. Col. "Smitty" Harris and his wife, Louise, epitomize the definition of commitment--to God, to country, and to family. This tale of extreme perseverance will restore your faith in the human spirit." --Brigadier General John Nichols, USAF "The incomprehensibly long ordeal of the Harris family is agonizing. Their love, faith, loyalty, and courage epitomize all that is good about America." --Lt. Col. Orson Swindle, USMC (ret.), POW, Hanoi, 11/11/1966 to 3/4/1973

How do the experts solve difficult problems in software development? In this unique and insightful book, leading computer scientists offer case studies that reveal how they found unusual, carefully designed solutions to high-profile projects. You will be able to look over the shoulder of major coding and design experts to see problems through their eyes. This is not simply another design patterns book, or another software engineering treatise on the right and wrong way to do things. The authors think aloud as they work through their project's architecture, the tradeoffs made in its construction, and when it was important to break rules. This book contains 33 chapters contributed by Brian Kernighan, KarlFogel, Jon Bentley, Tim Bray, Elliotte Rusty Harold, Michael Feathers,Alberto Savoia, Charles Petzold, Douglas Crockford, Henry S.

Unsparing and important. . . . An informative, clearheaded and sobering book.—Jonathan Yardley, Washington Post (1999 Critic's Choice) Inner-city black America is often stereotyped as a place of random violence, but in fact, violence in the inner city is regulated through an informal but well-known code of the street. This unwritten set of rules—based largely on an individual's ability to command respect—is a powerful and pervasive form of etiquette, governing the way in which people learn to negotiate public spaces. Elijah Anderson's incisive book delineates the code and examines it as a response to the lack of jobs that pay a living wage, to the stigma of race, to rampant drug use, to alienation and lack of hope.

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.

Aaron's Code tells the story of the first profound connection between art and computer technology. Here is the work of Harold Cohen - the renowned abstract painter who, at the height of a celebrated career in the late 1960's, abandoned the international scene of museums and galleries and sequestered himself with the most powerful computers he could get his hands on. What emerged from his long years of solitary struggle is an elaborate computer program that makes drawings autonomously, without human intervention - an electronic apprentice and alter ego called Aaron.

How the smartphone can become a personal concierge (not a stalker) in the mobile marketing revolution of smarter companies, value-seeking consumers, and curated offers. Consumers create a data trail by tapping their phones; businesses can tap into this trail to harness the power of the more than three trillion dollar mobile economy. According to Anindya Ghose, a global authority on the mobile economy, this two-way exchange can benefit both customers and businesses. In Tap, Ghose welcomes us to the mobile economy of smartphones, smarter companies, and value-seeking consumers. Drawing on his extensive research in the United States, Europe, and Asia, and on a variety of real-world examples from companies including Alibaba, China Mobile, Coke, Facebook, SK Telecom, Telefónica, and Travelocity, Ghose describes some intriguingly contradictory consumer behavior: people seek spontaneity, but they are predictable; they find advertising annoying, but they fear missing out; they value their privacy, but they increasingly use personal data as currency. When mobile advertising is done well, Ghose argues, the smartphone plays the role of a personal concierge—a butler, not a stalker. Ghose identifies nine forces that shape consumer behavior, including time, crowdedness, trajectory, and weather, and he examines these how these forces operate, separately and in combination. With Tap, he highlights the true influence mobile wields over shoppers, the behavioral and economic motivations behind that influence, and the lucrative opportunities it represents. In a world of artificial intelligence, augmented and virtual reality, wearable technologies, smart homes, and the Internet of Things, the future of the mobile economy seems limitless.
