    With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. With this book, you'll learn specific ways to write command-line applications that are easy to use, deploy, and maintain, using a set of clear best practices and the Ruby programming language. This book is designed to make any programmer or system administrator more productive in their job. Now updated for Ruby 2.Writing a command-line application that's self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, because it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Plus, Ruby has the support of a rich ecosystem of open source tools and libraries.Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason why a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users.With Ruby, the command line is not dead. Long live the command line.

    'Hitler knows that he will have to break us in this island or lose the war. If we can stand up to him, all Europe may be free and the life of the world will move forward into broad, sunlit uplands,' said Churchill. The future of Europe depended on Britain. A self-confident Herman Göring thought that it would be only a matter of weeks before his planes had forced Britain to surrender. The courage, resourcefulness and brilliant organisation of the RAF were to prove him wrong. By late September 1940, the RAF had proved invincible, thanks to the Vickers Supermarine Spitfire. It exceeded anything that any other air force possessed. RJ Mitchell, a shy and almost painfully modest engineer, was the genius behind the Spitfire. On the 5th March 1936, following its successful maiden flight, a legend was born.Prize-winning historian Leo McKinstry's vivid history of the Spitfire brings together a rich cast of characters and first hand testimonies. It is a tale full of drama and heroism, of glory and tragedy, with the main protagonist the remarkable plane that played a crucial role in saving Britain.

    But, although they use these patterns purposefully, they often use them informally and nearly unconsciously. This book organizes this substantial emerging "folklore" of system design -- with its rich language of system description -- and closes the gap between the useful abstractions (constructs and patterns) of system design and the current models, notations and tools. It identifies useful patterns clearly, gives examples, compares them, and evaluates their utility in various settings -- allowing readers to develop a repertoire of useful techniques that goes beyond the single-minded current fads. KEY TOPICS: Examines the ways in which architectural issues can impact software design; shows how to design new systems in principled ways using well-understood architectural paradigms; emphasizes informal descriptions, touching lightly on formal notations and specifications, and the tools that support them; explains how to understand and evaluate the design of existing software systems from an architectural perspective; and presents concrete examples of actual system architectures that can serve as models for new designs. MARKET: For professional software developers looking for new ideas about system organization.

     Many of those most closely involved in cracking the Enigma code – Alistair Denniston, Frank Birch, Dilly Knox – had wrestled with German naval codes for most of the First World War. By the end of the war they had been successfully cracking a new code every day, from their secret Room 40 at the Old Admiralty Building, in a London blacked out for Zeppelin Raids. The techniques they developed then, the ideas that they came to rely on, the people they came to trust, had been developed the hard way, under intense pressure and absolute secrecy during the First World War. Operation Primrose Operation Primrose tells the story of the capture of U-110 – and with it a working Enigma machine. One of the biggest secrets of the war, the capture of that one machine turned the tide of the war. Turing and his colleagues at Bletchley Park worked tirelessly to crack the code, and with the working Enigma machine they finally had their break-through moment. This book sets the story, and the Enigma cryptographers, in context – at the heart of the Battle of the Atlantic, when it reached its crescendo in the pursuit of the battleship Bismarck the week after U110 was taken. It sets Bletchley Park in its wider context too, at the heart of an intricate and maverick network of naval intelligence, tracking signals and plotting them to divert convoys around waiting U-boats, involving officers like James Bond’s future creator, Ian Fleming. It also sets out the most important context of all, forgotten in so much of the Enigma history: that Britain’s own naval code had already been cracked, and its signals were being read, thanks to the efforts of Turing’s opposite number, the German naval cryptographer, Wilhelm Tranow. An exciting and enthralling true story ‘Operation Primrose’ is an excellently researched piece on the race for naval supremacy in the Second World War. Alan Turing Mathematician, philosopher, codebreaker. Turing was one of the most original thinkers of the last century - and the man whose work helped create the computer-driven world we now inhabit. But he was also an enigmatic figure, deeply reticent yet also strikingly naïve. Turing’s openness about his homosexuality at a time when it was an imprisonable offence ultimately led to his untimely death at the age of only forty-one. Alan Turing: Unlocking the Enigma seeks to find the man behind the science, illuminating the life of a person who is still a shadowy presence behind his brilliant achievements. Turing was instrumental in cracking the Nazi Enigma machines at the top secret code breaking establishment at Bletchley Park during the Second World War. But his achievements were to be tragically overshadowed by his supposedly subversive views and for his sexuality. Praise for David Boyle: ‘The tone of the book may be gloomy but there is plenty of entertainment value …’ - Anne Ashworth, The Times ‘Exhilarating’ - Daily Mail ‘He tells these stories, on the whole persuasively and with some startling asides.
