We focus on building monitored and measurable applications. We also use tools that are designed to handle the challenges of managing Cloud, containerised and distributed applications and infrastructure.In the book we'll deliver:* An introduction to monitoring, metrics and measurement.* A scalable framework for monitoring hosts (including Docker and containers), services and applications built on top of the Riemann event stream processor. * Graphing and metric storage using Graphite and Grafana.* Logging with Logstash.* A framework for high quality and useful notifications* Techniques for developing and building monitorable applications* A capstone that puts all the pieces together to monitor a multi-tier application.

    It also works beautifully with other open source tools, such as the MySQL database and the Apache web server. However, as more web sites are developed in PHP, they become targets for malicious attackers, and developers need to prepare for the attacks.Security is an issue that demands attention, given the growing frequency of attacks on web sites. Essential PHP Security explains the most common types of attacks and how to write code that isn't susceptible to them. By examining specific attacks and the techniques used to protect against them, you will have a deeper understanding and appreciation of the safeguards you are about to learn in this book.In the much-needed (and highly-requested) Essential PHP Security, each chapter covers an aspect of a web application (such as form processing, database programming, session management, and authentication). Chapters describe potential attacks with examples and then explain techniques to help you prevent those attacks.Topics covered include:Preventing cross-site scripting (XSS) vulnerabilitiesProtecting against SQL injection attacksComplicating session hijacking attemptsYou are in good hands with author Chris Shiflett, an internationally-recognized expert in the field of PHP security. Shiflett is also the founder and President of Brain Bulb, a PHP consultancy that offers a variety of services to clients around the world.

    Machine learning provides these, developing methods that can automatically detect patterns in data and then use the uncovered patterns to predict future data. This textbook offers a comprehensive and self-contained introduction to the field of machine learning, based on a unified, probabilistic approach.The coverage combines breadth and depth, offering necessary background material on such topics as probability, optimization, and linear algebra as well as discussion of recent developments in the field, including conditional random fields, L1 regularization, and deep learning. The book is written in an informal, accessible style, complete with pseudo-code for the most important algorithms. All topics are copiously illustrated with color images and worked examples drawn from such application domains as biology, text processing, computer vision, and robotics. Rather than providing a cookbook of different heuristic methods, the book stresses a principled model-based approach, often using the language of graphical models to specify models in a concise and intuitive way. Almost all the models described have been implemented in a MATLAB software package—PMTK (probabilistic modeling toolkit)—that is freely available online. The book is suitable for upper-level undergraduates with an introductory-level college math background and beginning graduate students.

    Python is considered easy to learn, but there's no quicker way to mastery of the language than learning from an expert teacher. This edition of "Learning Python" puts you in the hands of two expert teachers, Mark Lutz and David Ascher, whose friendly, well-structured prose has guided many a programmer to proficiency with the language. "Learning Python," Second Edition, offers programmers a comprehensive learning tool for Python and object-oriented programming.

     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.
