Bletchley Park was where one of the war’s most famous – and crucial – achievements was made: the cracking of Germany’s “Enigma” code in which its most important military communications were couched. This country house in the Buckinghamshire countryside was home to Britain’s most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology – indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction – from Robert Harris and Ian McEwan to Andrew Hodges’ biography of Turing – what of the thousands of men and women who lived and worked there during the war? What was life like for them – an odd, secret territory between the civilian and the military? Sinclair McKay’s book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties – of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) – of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels – and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other’s work.

This book celebrates the 40th anniversary of the bar code and is written for those who over the years have asked the author what these bar codes are all about. It deals with why they were invented, who created them, how they are managed and used, whether they have been 'a good thing', how much longer they will last and what may replace them. It tells you how you can 'read between the lines' and 'what's in a number'. But it is not a detailed technical or historical account. It is an entertaining account full of stories and personalities designed to show that the term 'interesting bar codes' is not an oxymoron.

A primer on the underlying technologies that allow computer programs to work. Covers topics like computer hardware, combinatorial logic, sequential logic, computer architecture, computer anatomy, and Input/Output. Many coders are unfamiliar with the underlying technologies that make their programs run. But why should you care when your code appears to work? Because you want it to run well and not be riddled with hard-to-find bugs. You don't want to be in the news because your code had a security problem. Lots of technical detail is available online but it's not organized or collected into a convenient place. In The Secret Life of Programs, veteran engineer Jonathan E. Steinhart explores--in depth--the foundational concepts that underlie the machine. Subjects like computer hardware, how software behaves on hardware, as well as how people have solved problems using technology over time. You'll learn: How the real world is converted into a form that computers understand, like bits, logic, numbers, text, and colors The fundamental building blocks that make up a computer including logic gates, adders, decoders, registers, and memory Why designing programs to match computer hardware, especially memory, improves performance How programs are converted into machine language that computers understand How software building blocks are combined to create programs like web browsers Clever tricks for making programs more efficient, like loop invariance, strength reduction, and recursive subdivision The fundamentals of computer security and machine intelligence Project design, documentation, scheduling, portability, maintenance, and other practical programming realities. Learn what really happens when your code runs on the machine and you'll learn to craft better, more efficient code.

Americans spend more than $11 billion a year on self-help products—everything from books to diet pills to career coaches to seminars. So why—with all this time, money, and energy being spent—are so few people living the life they really want? Why are millions of smart, talented, motivated people still going through life with one foot on the brake? Here's the real Secret: You don't need any more how-to-succeed information to reach your full potential. The problem isn't lack of motivation or lack of information. The real problem is that most people focus on the "how-to" aspects of success taught by traditional self-help programs, without coming to terms with what productivity expert Noah St. John calls your "head trash"—the subconscious, emotional roadblocks that prevent people from acting on their real hopes, dreams, and ambitions. In this groundbreaking book, based on work with thousands of clients around the world, Noah St. John has created a remarkable, step-by-step approach that helps you achieve long-term happiness, success, and wealth. In The Secret Code of Success, you will learn how to: Eliminate the causes of self-sabotage and fear of success Allow yourself to make more money Remove stress while dramatically increasing personal productivity Improve relationships with coworkers, family, and friends Experience enhanced feelings of happiness, connection, and love The Secret Code of Success shows that, when it comes to success, the conscious mind is exactly the wrong place to start. It's only when we first conquer the self-sabotage of our subconscious (which accounts for 90 percent of our behavior) that we can truly begin to enjoy a life filled with success. This insight is at the core of The Secret Code of Success and leads to Noah's revolutionary 7-step method for eliminating these psychological obstacles. True financial freedom and personal success is possible at last! The Secret Code of Success shows you how to get your foot off the brake and start living the life you deserve.

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.
