The challenges faced by IBM's research and development laboratories, the technological paths they chose, and how these choices affected the company and the computer industry.

Computers and Society explores the history and impact of modern technology on everyday human life, considering its benefits, drawbacks, and repercussions. Particular attention is paid to new developments in artificial intelligence and machine learning, and the issues that have arisen from our complex relationship with AI.

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.

A celebration of the early years of the digital revolution, when computing power was deployed in a beige box on your desk. Today, people carry powerful computers in our pockets and call them “phones.” A generation ago, people were amazed that the processing power of a mainframe computer could be contained in a beige box on a desk. This book is a celebration of those early home computers, with specially commissioned new photographs of 100 vintage computers and a generous selection of print advertising, product packaging, and instruction manuals. Readers can recapture the glory days of fondly remembered (or happily forgotten) machines including the Commodore 64, TRS-80, Apple Lisa, and Mattel Aquarius—traces of the techno-utopianism of the not-so-distant past. Home Computers showcases mass-market success stories, rarities, prototypes, one-offs, and never-before-seen specimens. The heart of the book is a series of artful photographs that capture idiosyncratic details of switches and plugs, early user-interface designs, logos, and labels. After a general scene-setting retrospective, the book proceeds computer by computer, with images of each device accompanied by a short history of the machine, its inventors, its innovations, and its influence. Readers who inhabit today's always-on, networked, inescapably connected world will be charmed by this visit to an era when the digital revolution could be powered down every evening.

Thisvolume applies the praxeological and theoretical foundations of the personalist tradition to free-market economic theory. This work defends economic liberty in theologically sensitive terms that reference the personalist tradition, without compromising the disciplinary integrity of either economics or social ethics.
