To an outsider, the world of ham radio is one of basement transmitters, clunky microphones, Morse code, and crackly, possibly clandestine, worldwide communications, a world both mysterious and geeky. But the real story is a lot more interesting: indeed, there are more than two million operators worldwide, including people like Walter Cronkite and Priscilla Presley. Gandhi had a ham radio, as do Marlon Brando and Juan Carlos, king of Spain. Hello World takes us on a seventy-year odyssey through the world of ham radio. From 1927 until his death in 2001, operator Jerry Powell transmitted radio signals from his bedroom in Hackensack, New Jersey, touring the worlds most remote locations and communicating with people from Greenland to occupied Japan. Once he made contact with a fellow ham operator, he exchanged postcards known as QSLs cards with them. For seven decades, Powell collected hundreds of these cards, documenting his fascinating career in amateur radio and providing a dazzling graphic inventory of people and places far flung. This book is both an introduction to the fascinating world of ham and a visual feast for anyone interested in the universal language of graphic design.

This eBook edition of "Spacehounds of IPC (Sci-Fi Classic)" has been formatted to the highest digital standards and adjusted for readability on all devices. When the Inter-Planetary Corporation's (IPC) crack liner, IPV Arcturus, took off on a routine flight to Mars, it turned out to be the beginning of an unexpected and long voyage. There had been too many reports of errors in ship's flight positions from the Check Stations and brilliant physicist Dr. Percival ("Steve") Stevens is aboard the Arcturus on a fact-finding mission to find out what's really happening...

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.

What started out as a minor Project in 1987, blew out like the national debt so with all this accumulated info, it seemed worthwhile to produce the first book, here now is the Latest Online Edition. The sources and references have been many and varied and although the utmost care was taken, the Lists are far from complete and may contain errors. The original Codes etc were designed principally for marine use as this was the field in which radio was initially developed. The majority retain this influence but many have been modified and modernized to cover land and air applications. Technical terms have also varied as technology has changed however most abbreviations of the computer age have been omitted. These are specialist terms of that mode, not often encountered in telegraphy.
