Book excerpt: The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Download or read book Codebreaker Girls written by Jan Slimming and published by Casemate Publishers. This book was released on 2021-03-03 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: “What would it be like to keep a secret for fifty years? Never telling your parents, your children, or even your husband?” Codebreaker Girls: A Secret Life at Bletchley Park tells the true story of Daisy Lawrence. Following extensive research, the author uses snippets of information, unpublished photographs and her own recollections to describe scenes from her mother’s poor, but happy, upbringing in London, and the disruptions caused by the outbreak of the Second World War to a young woman in the prime of her life. The author asks why, and how, Daisy was chosen to work at the Government war station, as well as the clandestine operation she experienced with others, deep in the British countryside, during a time when the effects of the war were felt by everyone. In addition, the author examines her mother’s personal emotions and relationships as she searches for her young fiancée, who was missing in action overseas. The three years at Bletchley Park were Daisy’s university, but having closed the door in 1945 on her hidden role of national importance — dealing with Germany, Italy and Japan — this significant period in her life was camouflaged for decades in the filing cabinet of her mind. Now her story comes alive with descriptions, original letters, documents, newspaper cuttings and unique photographs, together with a rare and powerful account of what happened to her after the war. “Here’s a beauty of a history of some of the codebreaking girls who helped save us during the second world war. This one’s about Daisy Lawrence’s extraordinary life as a poor girl brought up in London and then chosen for top secret work at Bletchley Park. Reads like fiction.” —Books Monthly
Download or read book The Secret Code Breakers of Central Bureau written by David Dufty and published by . This book was released on 2023-02-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Bureau - Australia's own large and sophisticated intelligence network, built from scratch. It was this group of mathematicians, code-breakers, and radio experts who intercepted the travel plans of the architect of the Pearl Harbor attack, Admiral Yamamoto, leading to his ambush and death. Australian signals intelligence also played a vital role in the battles of the Coral Sea, Milne Bay, Hollandia, and many others. General Douglas MacArthur, the supreme commander of the local Allied forces, went so far as to insist that the men of Central Bureau accompany him on his counter-attack in the Pacific. After the war, the US sought to give these non-combatants the highest awards possible - honours that were suppressed by the Australian government in their need for secrecy. A groundbreaking work of military history, The Secret Code-breakers of Central Bureau gives these talented and dedicated individuals their due at last. It is a rich account of the shadowy side of military strength and of the men and women whose work was, in the words of the US navy, of 'immeasurable importance in the successfulmprosecution' of the Pacific War. 'Who knew? This enthralling study tells a deeply human story. The men and women who gave our troops a significant edge in the fight against the Japanese are the genuine heroes in this engaging and exciting book.' -Michael McKernan, author of The Strength of a Nation and When This Thing Happened 'This is history and military strategy written at its most engaging.' -Waikato Times 'A delightfully and thoroughly engaging story of the emergence of the Australian contribution to the signals and radio interception intelligence ... Dufty's writing style is light and easy to read, reminiscent of other contemporary historical narratives that tell a series of stories, most notably the emphasis of the human story associated with these experiences.' -Rhys Ball, NZ International Review

Book excerpt: This is a different science fiction book as it does not deal with invading aliens, but rather with peace loving aliens living in a more advanced world. Via radio and TV waves they know everything about us humans. By radio they communicate with us from a not-too-distant planet. The Aliens provide us humans with very advanced technologies in the fields of energy generation, medicine, computer science and artificial technology. These represent a quantum jump to our current state of development. This book also deals about how we humans deal with the impact of the introduction of these very advanced technologies and the politics which go with it. Therefore, this book is also a book of psychology of the human mind.
Download or read book Cracking Codes with Python written by Al Sweigart and published by No Starch Press. This book was released on 2018-01-23 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn how to program in Python while making and breaking ciphers—algorithms used to create and send secret messages! After a crash course in Python programming basics, you’ll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You’ll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today’s online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you’ll have learned how to code in Python and you’ll have the clever programs to prove it! You’ll also learn how to: - Combine loops, variables, and flow control statements into real working programs - Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish - Create test programs to make sure that your code encrypts and decrypts correctly - Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message - Break ciphers with techniques such as brute-force and frequency analysis There’s no better way to learn to code than to play with real programs. Cracking Codes with Python makes the learning fun!
