This one's a keeper." --Robert C. Martin "If you want to be an expert in the state of the art in TDD, you need to understand the ideas in this book."--Michael Feathers Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this simple idea takes skill and judgment to do well. Now there's a practical guide to TDD that takes you beyond the basic concepts. Drawing on a decade of experience building real-world systems, two TDD pioneers show how to let tests guide your development and "grow" software that is coherent, reliable, and maintainable. Steve Freeman and Nat Pryce describe the processes they use, the design principles they strive to achieve, and some of the tools that help them get the job done. Through an extended worked example, you'll learn how TDD works at multiple levels, using tests to drive the features and the object-oriented structure of the code, and using Mock Objects to discover and then describe relationships between objects. Along the way, the book systematically addresses challenges that development teams encounter with TDD--from integrating TDD into your processes to testing your most difficult features. Coverage includes - Implementing TDD effectively: getting started, and maintaining your momentum throughout the project - Creating cleaner, more expressive, more sustainable code - Using tests to stay relentlessly focused on sustaining quality - Understanding how TDD, Mock Objects, and Object-Oriented Design come together in the context of a real software development project - Using Mock Objects to guide object-oriented designs - Succeeding where TDD is difficult: managing complex test data, and testing persistence and concurrency

    One of the most coveted tools in a spy's arsenal, a zero day has the power to silently spy on your iPhone, dismantle the safety controls at a chemical plant, alter an election, and shut down the electric grid (just ask Ukraine).For decades, under cover of classification levels and non-disclosure agreements, the United States government became the world's dominant hoarder of zero days. U.S. government agents paid top dollar-first thousands, and later millions of dollars- to hackers willing to sell their lock-picking code and their silence. Then the United States lost control of its hoard and the market. Now those zero days are in the hands of hostile nations and mercenaries who do not care if your vote goes missing, your clean water is contaminated, or our nuclear plants melt down.Filled with spies, hackers, arms dealers, and a few unsung heroes, written like a thriller and a reference, This Is How They Tell Me the World Ends is an astonishing feat of journalism. Based on years of reporting and hundreds of interviews, The New York Times reporter Nicole Perlroth lifts the curtain on a market in shadow, revealing the urgent threat faced by us all if we cannot bring the global cyber arms race to heel.

    That principle is the value of slack, the degree of freedom in a company that allows it to change. Implementing slack could be as simple as adding an assistant to a department and letting high-priced talent spend less time at the photocopier and more time making key decisions, or it could mean designing workloads that allow people room to think, innovate, and reinvent themselves. It means embracing risk, eliminating fear, and knowing when to go slow. Slack allows for change, fosters creativity, promotes quality, and, above all, produces growth. With an approach that works for new- and old-economy companies alike, this revolutionary handbook debunks commonly held assumptions about real-world management, and gives you and your company a brand-new model for achieving and maintaining true effectiveness.

    The focus of this text is to solve real-world problems using the latest AI techniques. Intelligent systems like expert systems, fuzzy systems, artificial neural networks, genetic algorithms and ant colony systems are discussed in detail with case studies to facilitate in- depth understanding. Since the ultimate goal of AI is the construction of programs to solve problems, an entire chapter has been devoted to the programming languages used in AI problem solving. The theory is well supported by a large number of illustrations and end-chapter exercises. With its comprehensive coverage of the subject in a clear and concise manner this text would be extremely useful not only for undergraduate students, but also to postgraduate students.

     The research (conducted by the Center for the Study of Intent) uncovered a new dimension of human development and has revolutionized the way personal growth, meaning, happiness, and ultimately advanced spiritual topics such as ‘enlightenment’ are understood. The results, if you let them, will transform the quality of your life in ways you currently cannot even imagine as possible. During the research a formula was uncovered that is so effective at producing what seems like miracles in people’s lives it began to be referred to as the “God Formula” among participants and researchers. This book outlines that formula, and is the final version of the highly successful training material that was used with research participants. These researchers became the first scientists to successfully experiment with this new developmental continuum. The result has been the discovery of a series of techniques that lead from everyday consciousness to increased daily happiness and satisfaction, and finally to enlightenment and beyond (yes, there is a beyond!). This book covers the first stages of this process. You can view a summary of the results from the research phase that related to it, and later ones at: CenterForIntent.org/freedom. This book covers three primary components that combine to form a complete system of person growth, and an assortment of techniques for each component. While it provides the components, how they need to come together for maximum effectiveness will be unique to you. You’ll need to experiment with various combinations of these techniques until you find the one that works best for you. This may sound unusual. You’re probably used to reading books where the authors assert they have the one answer for everyone. The researchers at the Center tested an enormous number of techniques but didn’t find a single one that was helpful to more than a handful of individuals…when it was beneficial for anyone at all. However, they learned that there are a relatively small number of techniques that can be combined in ways that are incredibly effective. You just have to find the unique combination of these techniques that works for you right now. This book provides the distilled down wisdom from all of that testing. They were able to successfully identify core components from the methods that proved themselves. However, no one can tell you how to combine those components to get them to work best for you. People are simply too different for that to be possible. So, you’ll have to join the team, be your own scientist, and experiment! The good news is that the researchers spent an enormous amount of time and money narrowing down the possibilities for you. Most of the research participants were able to use this book to find the combination that worked for them quite quickly. It is likely the same will be true for you.It’s important that you not take the information this book contains lightly. Unlike other personal growth and self help books, this one is driven by a vast amount of actual research into what works. It was revised continually based on research participant feedback, so it’s very simple and easy to understand and use. But don’t let this simplicity fool you. Every line is there for a reason. This material has changed a lot of lives, if you’ll let it…yours can be next.
