With an introductory essay on cryptography and the history of code-breaking by Simon Singh, this book reveals the workings of Colossus and the extraordinary staff at Bletchley Park through personal accounts by those who lived and worked with the computer.

In 1940, almost a year after the outbreak of World War II, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, math, innovation, and improvisation, Bletchley Park code breakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these code breakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.

"I found The Between dark, super creepy, and pushing the limits of my limited amounts of courage to explore—but I couldn’t stop myself from coming back for more because it’s propulsive, addictive, and scary good fun." - Sean Gibson, author of The Part About the Dragon Was (Mostly) True While landscaping his backyard, ever-conscientious Paul Prentice discovers an iron door buried in the soil. His childhood friend and perpetual source of mischief, Jay Lightsey, pushes them to explore what's beneath. When the door slams shut above them, Paul and Jay are trapped in a between-worlds place of Escher-like rooms and horror story monsters, all with a mysterious connection to a command-line, dungeon explorer computer game from the early '80s called The Between. Unlike their childhood gaming, these men are facing life-and-death challenges; tensions rise between Jay and Paul as they encounter stranger things in each room, and their experience in arcade games and role-playing aren't enough to keep their partnership intact. Paul and Jay find themselves filling roles in a story that seems to play out over and over again. But in this world, where their roles warp their minds, the biggest threat to survival may not be the legendary monster Koŝmaro, risen from the Between's depths to hunt them; the biggest danger may be each other. hr Fans of The Goonies, Stranger Things, The Last Starfighter and Ready, Player One will thrill at the horror, adventure and humor that await them in The Between. hr "While in the first third of this book, I mentioned that the atmosphere reminded me of one of my favorite horror novels, SL Grey's The Mall. There's a surreal, not-right quality to that book that touched off a nerve in me that I just adored....I don't at all mean this as an insult, as that's a damn fun book- and so is this one! ....It's almost like a grown up, more gory and violent horror version of Heir Apparent." – Alexandra, Goodreads "This debut novel by author Ryan Leslie combines elements of science fiction and horror that at times reminded me of The Hike by Drew Magary and Off To Be The Wizard by Scott Meyer, all while being something distinctly different." – Matt, Goodreads “It was a great mix of horror, sci-fi and adventure gaming!” – Stephanie, Goodreads

The untold story of Bletchley Park's key role in the success of the Normandy campaign Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis' codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it. Using previously classified documents, David Kenyon casts the work of Bletchley Park in a new light, as not just a codebreaking establishment, but as a fully developed intelligence agency. He shows how preparations for the war's turning point--the Normandy Landings in 1944--had started at Bletchley years earlier, in 1942, with the careful collation of information extracted from enemy signals traffic. This account reveals the true character of Bletchley's vital contribution to success in Normandy, and ultimately, Allied victory.

This book constitutes the refereed proceedings of the 8th International Conference on Unconventional Computation, UC 2009, held in Ponta Delgada, Portugal, in September 2009. The 18 revised full papers presented together with 8 invited talks, 3 tutorials and 5 posters were carefully reviewed and selected from 40 submissions. The papers are devoted to all aspects of unconventional computation ranging from theoretical and experimental aspects to various applications. Typical topics are: natural computing including quantum; cellular, molecular, neural and evolutionary computing; chaos and dynamical system-based computing; and various proposals for computational mechanisms that go beyond the Turing model.

With the use of false transmissions and forged documents on a strategically placed dead body, Britain was able to perpetuate a great ruse on the Nazi Machine.

This book is an edition of the General Report on Tunny with commentary that clarifies the often difficult language of the GRT and fitting it into a variety of contexts arising out of several separate but intersecting story lines, some only implicit in the GRT. Explores the likely roots of the ideas entering into the Tunny cryptanalysis Includes examples of original worksheets, and printouts of the Tunny-breaking process in action Presents additional commentary, biographies, glossaries, essays, and bibliographies

Henry Miller’s landmark travel book, now reissued in a new edition, is ready to be stuffed into any vagabond’s backpack. Like the ancient colossus that stood over the harbor of Rhodes, Henry Miller’s The Colossus of Maroussi stands as a seminal classic in travel literature. It has preceded the footsteps of prominent travel writers such as Pico Iyer and Rolf Potts. The book Miller would later cite as his favorite began with a young woman’s seductive description of Greece. Miller headed out with his friend Lawrence Durrell to explore the Grecian countryside: a flock of sheep nearly tramples the two as they lie naked on a beach; the Greek poet Katsmbalis, the “colossus” of Miller’s book, stirs every rooster within earshot of the Acropolis with his own loud crowing; cold hard-boiled eggs are warmed in a village’s single stove, and they stay in hotels that “have seen better days, but which have an aroma of the past.”
