O que é Blockchain? Blockchain é uma tecnologia de registro distribuído que permite a manutenção de uma base de dados segura e confiável. Ela é baseada em um sistema de blocos encadeados, cada um contendo um conjunto de informações. Esses blocos são protegidos por criptografia e distribuídos por uma rede de computadores. As principais características do Blockchain são: Descentralização: a rede Blockchain não é controlada por um único órgão ou entidade, mas por uma rede de computadores. Isso torna a tecnologia mais segura e confiável. Transparência: todas as transações registradas no Blockchain são públicas e podem ser consultadas por qualquer pessoa. Imutabilidade: uma vez registrado, um bloco não pode ser alterado ou excluído. O que são Criptomoedas? Criptomoedas são moedas digitais que usam a tecnologia Blockchain para registrar suas transações. Elas são descentralizadas, transparentes e imutáveis. As principais criptomoedas são: Bitcoin: a primeira e mais popular criptomoeda. Ethereum: uma plataforma de contratos inteligentes que também pode ser usada para criar criptomoedas. Tether: uma stablecoin atrelada ao dólar americano. Saiba mais...
What others in the trenches say about The Pragmatic Programmer... “The cool thing about this book is that it’s great for keeping the programming process fresh. The book helps you to continue to grow and clearly comes from people who have been there.” — Kent Beck, author of Extreme Programming Explained: Embrace Change “I found this book to be a great mix of solid advice and wonderful analogies!” — Martin Fowler, author of Refactoring and UML Distilled “I would buy a copy, read it twice, then tell all my colleagues to run out and grab a copy. This is a book I would never loan because I would worry about it being lost.” — Kevin Ruland, Management Science, MSG-Logistics “The wisdom and practical experience of the authors is obvious. The topics presented are relevant and useful.... By far its greatest strength for me has been the outstanding analogies—tracer bullets, broken windows, and the fabulous helicopter-based explanation of the need for orthogonality, especially in a crisis situation. I have little doubt that this book will eventually become an excellent source of useful information for journeymen programmers and expert mentors alike.” — John Lakos, author of Large-Scale C++ Software Design “This is the sort of book I will buy a dozen copies of when it comes out so I can give it to my clients.” — Eric Vought, Software Engineer “Most modern books on software development fail to cover the basics of what makes a great software developer, instead spending their time on syntax or technology where in reality the greatest leverage possible for any software team is in having talented developers who really know their craft well. An excellent book.” — Pete McBreen, Independent Consultant “Since reading this book, I have implemented many of the practical suggestions and tips it contains. Across the board, they have saved my company time and money while helping me get my job done quicker! This should be a desktop reference for everyone who works with code for a living.” — Jared Richardson, Senior Software Developer, iRenaissance, Inc. “I would like to see this issued to every new employee at my company....” — Chris Cleeland, Senior Software Engineer, Object Computing, Inc. “If I’m putting together a project, it’s the authors of this book that I want. . . . And failing that I’d settle for people who’ve read their book.” — Ward Cunningham Straight from the programming trenches, The Pragmatic Programmer cuts through the increasing specialization and technicalities of modern software development to examine the core process--taking a requirement and producing working, maintainable code that delights its users. It covers topics ranging from personal responsibility and career development to architectural techniques for keeping your code flexible and easy to adapt and reuse. Read this book, and you'll learn how to Fight software rot; Avoid the trap of duplicating knowledge; Write flexible, dynamic, and adaptable code; Avoid programming by coincidence; Bullet-proof your code with contracts, assertions, and exceptions; Capture real requirements; Test ruthlessly and effectively; Delight your users; Build teams of pragmatic programmers; and Make your developments more precise with automation. Written as a series of self-contained sections and filled with entertaining anecdotes, thoughtful examples, and interesting analogies, The Pragmatic Programmer illustrates the best practices and major pitfalls of many different aspects of software development. Whether you're a new coder, an experienced programmer, or a manager responsible for software projects, use these lessons daily, and you'll quickly see improvements in personal productivity, accuracy, and job satisfaction. You'll learn skills and develop habits and attitudes that form the foundation for long-term success in your career. You'll become a Pragmatic Programmer.
Since the early 2000s, state-led and innovation-focused strategies have characterized the approach to development pursued in countries around the world, such as China, India, and South Korea. Brazil, the largest and most industrialized economy in Latin America, demonstrates both the opportunities and challenges of this approach. Over the course of nearly 20 years, the Brazilian government enacted various policies and programs designed to strengthen the country’s capacity to innovate. It increased spending on science and technology, encouraged greater collaboration between industry and universities, and fostered the creation of new institutions whose primary aim was to facilitate greater private research and development (R&D) spending. In this book, the editors unite a diverse array of empirical contributions around a few key themes, including public policies, institutions and innovation ecosystems, and firms and industries, that collectively make the case for a new, forward-looking innovation agenda aimed at addressing persistent challenges and exploiting emerging opportunities in Brazil. Its conclusions offer valuable lessons for other developing and emerging economies seeking to accelerate innovation and growth in the modern age. With its interdisciplinary and wide-ranging contribution to the study of innovation, as well as attention to broader policy implications, this book will appeal to scholars and professionals alike.
The present water report is the final product emanating from efforts by FAO, IWMI and others to document and understand the implications of the irrigation sector embarking on a wide reform process. It is intended to be a knowledge synthesis document that captures the global experiences emerging from a wide-reaching process targeting the reform of the irrigation sector. This study indicates that irrigation management transfer (IMT) is an approach for irrigation sector reform with the potential to improve the sustainability of irrigation systems. The process requires inter alia strong political commitment, negotiations among stakeholders, and long-term capacity development. Irrigation management transfer should not be seen as a process that has a clear "beginning" and "end". While the former can be more easily identified, the latter is much more difficult to determine. In fact, IMT can be the initial stage of an evolving long reform process. The accompanying CD-ROM contains IMT country profiles and case studies, an international IMT e-mail conference, a bibliography and links.--Publisher's description.
Jennifer Michael Hecht explodes the myths about happiness, liberating us from the message that there's only one way to care for our hearts, minds, and bodies.
A collection of essays that sets forth the moral principles of Objectivism, Ayn Rand's controversial, groundbreaking philosophy. Since their initial publication, Rand's fictional works—Anthem, The Fountainhead, and Atlas Shrugged—have had a major impact on the intellectual scene. The underlying theme of her famous novels is her philosophy, a new morality—the ethics of rational self-interest—that offers a robust challenge to altruist-collectivist thought. Known as Objectivism, her divisive philosophy holds human life—the life proper to a rational being—as the standard of moral values and regards altruism as incompatible with man's nature. In this series of essays, Rand asks why man needs morality in the first place, and arrives at an answer that redefines a new code of ethics based on the virtue of selfishness.
