    The language and tasks discussed in my former books are very complex. He asked me to write something basic that everyone can understand. So, I thought to write about Hacking with a Smartphones, a readily available tool to everyone in this 21st Century. Even a rickshaw driver today who earns hundred rupees a day owns a Smartphone. Understandably, none of us want our data to be hacked by a rickshaw driver, but the tricks and methods in this book have been explained so easily that even they can clench it. With the craze of e-shopping and net banking increasing the rate of cyber crime is increasing too. This book will tell you simple countermeasures about smart phones and digital security, they are simple but dangerous. Note: Don't expect big hacking techniques through this book, it may disappoint you. #hackinstagram #spyandroidmobile #whatsapphacking #iPhoneHacking

    Not any more. Wordpress makes it possible for anyone to create and run a professional looking website.While Wordpress is an amazing tool, the truth is it does have a steep learning curve, even if you have built websites before. Therefore, the goal of this book is to take anyone, even a complete beginner and get them building a professional looking website. I'll hold your hand, step-by-step, all the way. As I was planning this book, I made one decision early on. I wanted to use screenshots of everything, so the reader wasn't left looking for something on their screen that I was describing in text. This book has screenshots. I haven't counted them all, but it must be close to 300. These screenshots will help you find the things I am talking about. They'll help you check your settings and options against the screenshot of mine. No more doubt, no more wondering if you have it correct. Look, compare and move on to the next section.With so many screenshots, you may be worried that the text might be a little on the skimpy side. No need to worry there. I have described in the minutest detail, every step on your journey to a great looking website. In all, this book has over 35,000 words. This book will cut your learning curve associated with WordpressEvery chapter of the book ends with a "Tasks to Complete" section. By completing these tasks, you'll not only become proficient at using Wordpress, you'll become confident & enjoy using Wordpress.

    If you're a desktop, mobile or web developer, this book is your blueprint to getting your startup off the ground with no outside investment.This book intentionally avoids topics restricted to venture-backed startups such as: honing your investment pitch, securing funding, and figuring out how to use the piles of cash investors keep placing in your lap.This book assumes:* You don't have $6M of investor funds sitting in your bank account* You're not going to relocate to the handful of startup hubs in the world* You're not going to work 70 hour weeks for low pay with the hope of someday making millions from stock optionsThere's nothing wrong with pursuing venture funding and attempting to grow fast like Amazon, Google, Twitter, and Facebook. It just so happened that most people are not in a place to do this.

    

    In a few years, it's expected to be found inside millions of cell phones and other mobile devices, making Android a major platform for application developers. That could be your own program running on all those devices.Getting started developing with Android is easy. You don't even need access to an Android phone, just a computer where you can install the Android SDK and the phone emulator that comes with it. Within minutes, "Hello, Android" will get you creating your first working application: Android's version of "Hello, World."From there, you'll build up a more substantial example: an Android Sudoku game. By gradually adding features to the game throughout the course of the book, you'll learn about many aspects of Android programming including user interfaces, multimedia, and the Android life cycle.If you're a busy developer who'd rather be coding than reading about coding, this book is for you. To help you find what you need to know fast, each chapter ends with "Fast forward" section. These sections provide guidance for where you should go next when you need to read the book out of order.

    It offers on expressiveness and safety without compromising simplicity, seamless interoperability with existing Java code, and great tooling support. Because Kotlin generates regular Java bytecode and works together with existing Java libraries and frameworks, it can be used almost everywhere where Java is used today - for server-side development, Android apps, and much more.Kotlin in Action takes experienced Java developers from the language basics all the way through building applications to run on the JVM and Android devices. Written by core developers of Kotlin, this example-rich book begins by teaching you the basic syntax of the Kotlin language. Then you’ll learn how to use features that let you build reusable abstractions, higher-level functions, libraries, and even entire domain specific languages. Finally, you’ll focus on details of applying Kotlin in real-world projects, such as build system integration, Android support and concurrent programming.

    The Reactive Application model addresses these demands through new patterns designed to "react" effectively to user and system events, changes in load, competition for shared system resources, and unanticipated failures. Although reactive design patterns can be implemented using standard enterprise development tools, you best realize the benefits when you pair them with a functional programming language like Scala and an Actor-based concurrency system like Akka.Reactive Design Patterns is a clearly-written guide for building event-driven distributed systems that are resilient, responsive, and scalable. Written by the authors of the Reactive Manifesto, this book teaches you to apply reactive design principles to the real problems of distributed application development. You'll discover technologies and paradigms that can be used to build reactive applications including Akka and other actor-based systems, functional programming, replication and distribution, and implementation techniques such as futures, iteratees, and reactive streams. While the book presents concrete examples in Scala, Java, JavaScript, and Erlang, the primary goal is to introduce patterns and best practices that you can use to apply reactive principles to common problems you'll face when building distributed systems.WHAT'S INSIDE* Discover best practices and patterns for building responsive applications* Build applications that can withstand hardware or software failure at any level* Patterns for fault tolerance, scalability, and responsiveness* Maximize multicore hardware using asynchronous and event-driven solutions* Scale applications under tremendous loadReaders should be familiar with a standard programming language like Java, C++ or C# and be comfortable with the basics of distributed systems. Software engineers and architects will learn how to avoid common pitfalls and apply patterns for solving day-to-day problems in a fault-tolerant and scalable way to maximize their application's responsiveness to users and clients. Project leaders and CTOs will gain a deeper understanding of the philosophy behind resilience and scalability in distributed systems, as well as their limitations, challenges and benefits.

    Throughout the book, the authors share their insights into Swift to ensure that you understand the hows and whys of Swift and can put that understanding to use in different contexts. After working through the book, you will have the knowledge and confidence to develop your own solutions to a wide range of programming challenges using Swift.

    This lively book reveals oddities of the Java programming language through entertaining and thought-provoking programming puzzles.--Guy Steele, Sun Fellow and coauthor of The Java(TM) Language SpecificationI laughed, I cried, I threw up (my hands in admiration).--Tim Peierls, president, Prior Artisans LLC, and member of the JSR 166 Expert GroupHow well do you really know Java? Are you a code sleuth? Have you ever spent days chasing a bug caused by a trap or pitfall in Java or its libraries? Do you like brainteasers? Then this is the book for you!In the tradition of Effective Java(TM), Bloch and Gafter dive deep into the subtleties of the Java programming language and its core libraries. Illustrated with visually stunning optical illusions, Java(TM) Puzzlers features 95 diabolical puzzles that educate and entertain. Anyone with a working knowledge of Java will understand the puzzles, but even the most seasoned veteran will find them challenging.Most of the puzzles take the form of a short program whose behavior isn't what it seems. Can you figure out what it does? Puzzles are grouped loosely according to the features they use, and detailed solutions follow each puzzle. The solutions go well beyond a simple explanation of the program's behavior--they show you how to avoid the underlying traps and pitfalls for good. A handy catalog of traps and pitfalls at the back of the book provides a concise taxonomy for future reference.Solve these puzzles and you'll never again fall prey to the counterintuitive or obscure behaviors that can fool even the most experienced programmers.

    On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, author C.J. Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:Should database access granted be through views instead of base tables? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Could you write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports "quantified comparisons," but they're better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don't support them properly. What can you do to resolve this situation? Database theory and practice have evolved since Edgar Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.
