Xamarin.Forms lets you write shared user-interface code in C# and XAML that maps to native controls on these three platforms.

    But developing these systems brings its own set of headaches. With lots of examples and practical advice, this book takes a holistic view of the topics that system architects and administrators must consider when building, managing, and evolving microservice architectures.Microservice technologies are moving quickly. Author Sam Newman provides you with a firm grounding in the concepts while diving into current solutions for modeling, integrating, testing, deploying, and monitoring your own autonomous services. You'll follow a fictional company throughout the book to learn how building a microservice architecture affects a single domain.Discover how microservices allow you to align your system design with your organization's goalsLearn options for integrating a service with the rest of your systemTake an incremental approach when splitting monolithic codebasesDeploy individual microservices through continuous integrationExamine the complexities of testing and monitoring distributed servicesManage security with user-to-service and service-to-service modelsUnderstand the challenges of scaling microservice architectures

    This book explains the technical aspects of hacking, including stack based overflows, heap based overflows, string exploits, return-into-libc, shellcode, and cryptographic attacks on 802.11b.

    Why is this open-source tool so popular? Because it automates a tedious task: persisting your Java objects to a relational database. The inevitable mismatch between your object-oriented code and the relational database requires you to write code that maps one to the other. This code is often complex, tedious and costly to develop. Hibernate does the mapping for you.Not only that, Hibernate makes it easy. Positioned as a layer between your application and your database, Hibernate takes care of loading and saving of objects. Hibernate applications are cheaper, more portable, and more resilient to change. And they perform better than anything you are likely to develop yourself."Hibernate in Action" carefully explains the concepts you need, then gets you going. It builds on a single example to show you how to use Hibernate in practice, how to deal with concurrency and transactions, how to efficiently retrieve objects and use caching.The authors created Hibernate and they field questions from the Hibernate community every day-they know how to make Hibernate sing. Knowledge and insight seep out of every pore of this book."What's Inside"- ORM concepts- Getting started- Many real-world tasks- The Hibernate application development process

    By the end of the book, you'll understand how to develop a large, maintainable, and performant application with AngularJS.Guided by two engineers who worked on AngularJS at Google, you'll learn the components needed to build data-driven applications, using declarative programming and the Model-view-controller pattern. You'll also learn how to conduct unit tests on each part of your application.Learn how to use controllers for moving data to and from viewsUnderstand when to use AngularJS services instead of controllersCommunicate with the server to store, fetch, and update data asynchronouslyKnow when to use AngularJS filters for converting data and values to different formatsImplement single-page applications, using ngRoute to select views and navigationDive into basic and advanced directives for creating reusable componentsWrite an end-to-end test on a live version of your entire applicationUse best practices, guidelines, and tools throughout the development cycle

    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.

     -Byte, September 1995 I can't begin to tell you how many pleasurable hours of study and recreation they have afforded me! I have pored over them in cars, restaurants, at work, at home... and even at a Little League game when my son wasn't in the line-up. -Charles Long If you think you're a really good programmer... read [Knuth's] Art of Computer Programming... You should definitely send me a resume if you can read the whole thing. -Bill Gates It's always a pleasure when a problem is hard enough that you have to get the Knuths off the shelf. I find that merely opening one has a very useful terrorizing effect on computers. -Jonathan Laventhol This first volume in the series begins with basic programming concepts and techniques, then focuses more particularly on information structures-the representation of information inside a computer, the structural relationships between data elements and how to deal with them efficiently. Elementary applications are given to simulation, numerical methods, symbolic computing, software and system design. Dozens of simple and important algorithms and techniques have been added to those of the previous edition. The section on mathematical preliminaries has been extensively revised to match present trends in research. Ebook (PDF version) produced by Mathematical Sciences Publishers (MSP), http: //msp.org

    The chafing restrictions of a typical upbringing in upper-class, small town Alabama simply did not apply to Zelda, who was described as an unusual child and permitted to roam the streets with little supervision. Zelda refused to blossom into a typical 'Southern belle' on anyone's terms but her own and while still in high school enjoyed the status of a local celebrity for her shocking behavior. Everybody in town knew the name Zelda Sayre. Queen of the Montgomery social scene, Zelda had a different beau ready and willing to show her a good time for every day of the week. Before meeting F. Scott Fitzgerald, Zelda's life was a constant pursuit of pleasure. With little thought for the future and no responsibilities to speak of, Zelda committed herself fully to the mantra that accompanied her photo in her high school graduation book: "Why should all life be work, when we all can borrow. Let's think only of today, and not worry about tomorrow." But for now Zelda was still in rehearsal for her real life to begin, a life she was sure would be absolutely extraordinary. Zelda Sayre married F. Scott Fitzgerald on the 3rd of April 1920 and left sleepy Montgomery behind in order to dive headfirst into the shimmering, glamourous life of a New York socialite. With the publication of Scott's first novel, This Side of Paradise, Zelda found herself thrust into the limelight as the very epitome of the Flapper lifestyle. Concerned chiefly with fashion, wild parties and flouting social expectations, Zelda and Scott became icons of the Jazz Age, the personification of beauty and success. What Zelda and Scott shared was a romantic sense of self-importance that assured them that their life of carefree leisure and excess was the only life really worth living. Deeply in love, the Fitzgeralds were like to sides of the same coin, each reflecting the very best and worst of each other. While the world fell in love with the image of the Fitzgeralds they saw on the cover of magazines, behind the scenes the Fitzgerald's marriage could not withstand the tension of their creative arrangement. Zelda was Scott's muse and he mercilessly mined the events of their life for material for his books. Scott claimed Zelda's memories, things she said, experiences she had and even passages from her diary as his possessions and used them to form the basis of his fictional works. Zelda had a child but the domestic sphere offered no comfort or purpose for her. The Flapper lifestyle was not simply a phase she lived through, it formed the very basis of her character and once the parties grew dull, the Fitzgeralds' drinking became destructive and Zelda's beauty began to fade, the world held little allure for her. Zelda sought reprieve in work and tried to build a career as a ballet dancer. When that didn't work out she turned to writing but was forbidden by Scott from using her own life as material. Convinced that she would never leave her mark on the world as deeply or expressively as Scott had, Zelda retreated into herself and withdrew from the people she knew in happier times. The later years of Zelda's life were marred by her detachment from reality as, diagnosed with schizophrenia, Zelda spent the last eighteen years of her life living in and out of psychiatric hospitals. As Scott's life unraveled due to alcohol abuse, Zelda looked back on the years they had spent together, young and wild and beautiful, as the best of her life. She may have been right but she was wrong about one thing, Zelda did leave her mark on the world and it was a deep and expressive mark that no one could have left but her. Zelda Fitzgerald: The Biography

    - Build an Angular 2 application from scratch using TypeScript and the Angular command line interface. - Write code using the paradigm of reactive programming with RxJS and Observables. - Know how to Unit Test Angular 2 using Jasmine, Karma and the Angular Test Bed The first chapter in the course is a quickstart where you dive straight into writing your first Angular 2 application. We use the web editor plunker so you can get stuck in writing code ASAP. In this quickstart you'll get a 50,000 foot view of the major features of Angular 2. Then chapter by chapter we go much deeper into each of these features. I'll cover the theory for that feature, using plunker as much as possible so you can try out the code yourself in a browser. Then you'll practice what you've learnt with either an online quiz or a set of flash cards. You are going to learn all about:- - Typescript & ES6 Javascript. - Components & Binding - Directives - Dependancy Injection & Services - Angular Modules & Bootstrapping your Angular application. - SPAs & Routing - Angular CLI - Forms - Reactive Programming with RXJs - HTTP - Unit Testing The ideal student is an existing web developer, with some JavaScript knowledge that wants to add Angular 2 to their skill set. Or perhaps you are an existing Angular 1 developer who wants to level up to Angular 2. You do need to be comfortable with at least the ES5 version of JavaScript. We'll be using a UI framework called twitter bootstrap throughout the course but you still must know HTML and some CSS.
