It has made countless new businesses possible and presents a massive opportunity for large enterprises to innovate like startups and retire decades of technical debt. But making the most of the cloud requires much more from enterprises than just a technology change. Stephen Orban led Dow Jones’s journey toward digital agility as their CIO and now leads AWS’s Enterprise Strategy function, where he helps leaders from the largest companies in the world transform their businesses. As he demonstrates in this book, enterprises must re-train their people, evolve their processes, and transform their cultures as they move to the cloud. By bringing together his experiences and those of a number of business leaders, Orban shines a light on what works, what doesn’t, and how enterprises can transform themselves using the cloud.

    We start off easy, defining some of the tech lingo you may have heard before, but didn’t fully understand. From there, each lesson introduces something new, slowly building up to the point where you are confident about what an API is and, for the brave, could actually take a stab at using one.

    Perhaps you've taken on a larger project than the ones you're used to. Or you want to add a user interface or a networking component. Or you need to do more complicated error trapping.Whether your knowledge of Perl is casual or deep, this book will make you a more accomplished programmer. Here you can learn the complex techniques for production-ready Perl programs. This book explains methods for manipulating data and objects that may have looked like magic before. Furthermore, it sets Perl in the context of a larger environment, giving you the background you need for dealing with networks, databases, and GUIs. The discussion of internals helps you program more efficiently and embed Perl within C or C within Perl.Major topics covered include:Practical use of packages and classes (object-oriented programming) Complex data structures Persistence (e.g., using a database) Networking Graphical interfaces, using the Tk toolkit Interaction with C language functions Embedding and extending the Perl interpreterIn addition, the book patiently explains all sorts of language details you've always wanted to know more about, such as the use of references, trapping errors through the eval operator, non-blocking I/O, when closures are helpful, and using ties to trigger actions when data is accessed. You will emerge from this book a better hacker, and a proud master of Perl.

    With few exceptions, existing books are overly technical, only dedicate a single chapter to website vulnerabilities or don't include any real world examples. This book is different.Using publicly disclosed vulnerabilities, Web Hacking 101 explains common web vulnerabilities and will show you how to start finding vulnerabilities and collecting bounties. With over 30 examples, the book covers topics like:HTML InjectionCross site scripting (XSS)Cross site request forgery (CSRF)Open RedirectsRemote Code Execution (RCE)Application Logicand more...Each example includes a classification of the attack, a report link, the bounty paid, easy to understand description and key takeaways. After reading this book, your eyes will be opened to the wide array of vulnerabilities that exist and you'll likely never look at a website or API the same way.

    Billions of interconnected devices will be monitoring the environment, transportation systems, factories, farms, forests, utilities, soil and weather conditions, oceans and resources Many of these sensors and actuators will be networked into autonomous sets, with much of the information being exchanged machine-to-machine directly and without human involvement. Machine-to-machine communications are typically terse. Most sensors and actuators will report or act upon small pieces of information - chirps. Burdening these devices with current network protocol stacks is inefficient, unnecessary and unduly increases their cost of ownership. This must change. The architecture of the Internet of Things will entail a widely distributed topology incorporating simpler chirp protocols towards at the edges of the network. Rethinking the Internet of Things describes reasons why we must rethink current approaches to the Internet of Things. Appropriate architectures that will coexist with existing networking protocols are described in detail. An architecture comprised of integrator functions, propagator nodes, and end devices, along with their interactions, is explored. What you'll learn Teaches the difference between the "normal" Internet and the Internet of Things, Describes a new architecture and its components in the "chirp" context. Explains the shortcomings of IP for IoT. Describes the anatomy of the IoT. Re-frames key ideas such as reliability. Describes how to build the IoT Who this book is forThought leaders, executives, architectural, standards and development leaders in the evolving IoT industry

    This book is aimed at the working Rails developer who is looking to grow and evolve Rails projects while keeping them flexible, maintainable, and robust. The focus is on pragmatic solutions which tread a “middle way” between the expedience of the Rails “golden path”, and rigid OO purity.

    His assignment is to program the complex lunar landing phase in the Lunar Module's onboard computer. As he masters his art the reader learns about the computer, the mission, and a bit about spacecraft navigation and meets a cast of interesting characters along the way. As Apollo 11 approaches, the author flies lunar landings in simulators and meets the astronauts who will fly the LM for real. He explains the computer alarms that almost prevented Neil Armstrong from landing and describes a narrow escape from another dangerous problem. He helps Pete Conrad achieve a pinpoint landing on Apollo 12, and works with Apollo 16 commander John Young on a technique for landing even more precisely. On Apollo 14 he devises a workaround when a faulty pushbutton threatens Alan Shepard's mission, earning a NASA award, a story in Rolling Stone, and a few lines in the history books. Along the way the author hits the high points of his eclectic personal life, as he enters adulthood in the 1960s. He writes for students of the Apollo project, for whom the development of the flight software is still largely unexplored territory, but also for the young coders of the current digital culture, who will get the author's observations on the art of programming and who may identify as he explores sex, drugs, and the other excitements of the era. The underlying thesis is that the American space program in the 1960s was successful not in spite of, but in large measure because of the idealism, the freedom of thought, and the sense of exploration, inner and outer, that prevailed in the culture during that period. The memoir concludes in a party atmosphere at the spectacular night launch of Apollo 17 before a glittery crowd an occasion that marked the high water mark, so far, of human space exploration.
