World Without Mind: The Existential Threat of Big Tech
by Franklin FoerFranklin Foer reveals the existential threat posed by big tech, and in his brilliant polemic gives us the toolkit to fight their pervasive influence. Over the past few decades there has been a revolution in terms of who controls knowledge and information. This rapid change has imperiled the way we think. Without pausing to consider the cost, the world has rushed to embrace the products and services of four titanic corporations. We shop with Amazon; socialize on Facebook; turn to Apple for entertainment; and rely on Google for information. These firms sell their efficiency and purport to make the world a better place, but what they have done instead is to enable an intoxicating level of daily convenience. As these companies have expanded, marketing themselves as champions of individuality and pluralism, their algorithms have pressed us into conformity and laid waste to privacy. They have produced an unstable and narrow culture of misinformation, and put us on a path to a world without private contemplation, autonomous thought, or solitary introspection—a world without mind. In order to restore our inner lives, we must avoid being coopted by these gigantic companies, and understand the ideas that underpin their success. Elegantly tracing the intellectual history of computer science—from Descartes and the enlightenment to Alan Turing to Stuart Brand and the hippie origins of today's Silicon Valley—Foer exposes the dark underpinnings of our most idealistic dreams for technology. The corporate ambitions of Google, Facebook, Apple, and Amazon, he argues, are trampling longstanding liberal values, especially intellectual property and privacy. This is a nascent stage in the total automation and homogenization of social, political, and intellectual life. By reclaiming our private authority over how we intellectually engage with the world, we have the power to stem the tide. At stake is nothing less than who we are, and what we will become. There have been monopolists in the past but today's corporate giants have far more nefarious aims. They’re monopolists who want access to every facet of our identities and influence over every corner of our decision-making. Until now few have grasped the sheer scale of the threat. Foer explains not just the looming existential crisis but the imperative of resistance.
Worried About the Wrong Things: Youth, Risk, and Opportunity in the Digital World (The John D. and Catherine T. MacArthur Foundation Series on Digital Media and Learning)
by Jacqueline Ryan VickeryWhy media panics about online dangers overlook another urgent concern: creating equitable online opportunities for marginalized youth.It's a familiar narrative in both real life and fiction, from news reports to television storylines: a young person is bullied online, or targeted by an online predator, or exposed to sexually explicit content. The consequences are bleak; the young person is shunned, suicidal, psychologically ruined. In this book, Jacqueline Ryan Vickery argues that there are other urgent concerns about young people's online experiences besides porn, predators, and peers. We need to turn our attention to inequitable opportunities for participation in a digital culture. Technical and material obstacles prevent low-income and other marginalized young people from the positive, community-building, and creative experiences that are possible online.Vickery explains that cautionary tales about online risk have shaped the way we think about technology and youth. She analyzes the discourses of risk in popular culture, journalism, and policy, and finds that harm-driven expectations, based on a privileged perception of risk, enact control over technology. Opportunity-driven expectations, on the other hand, based on evidence and lived experience, produce discourses that acknowledge the practices and agency of young people rather than seeing them as passive victims who need to be protected.Vickery first addresses how the discourses of risk regulate and control technology, then turns to the online practices of youth at a low-income, minority-majority Texas high school. She considers the participation gap and the need for schools to teach digital literacies, privacy, and different online learning ecologies. Finally, she shows that opportunity-driven expectations can guide young people's online experiences in ways that balance protection and agency.

X-Machines for Agent-Based Modeling: FLAME Perspectives (Chapman & Hall/CRC Computer and Information Science Series)
by Mariam KiranFrom the Foreword: "This book exemplifies one of the most successful approaches to modeling and simulating [the] new generation of complex systems. FLAME was designed to make the building of large scale complex systems models straightforward and the simulation code that it generates is highly efficient and can be run on any modern technology. FLAME was the first such platform that ran efficiently on high performance parallel computers and a version for GPU technology is also available. At its heart, and the reason why it is so efficient and robust, is the use of a powerful computational model ‘Communicating X-machines’ which is general enough to cope with most types of modelling problems. As well as being increasingly important in academic research, FLAME is now being applied in industry in many different application areas. This book describes the basics of FLAME and is illustrated with numerous examples."—Professor Mike Holcombe, University of Sheffield, UK Agent-based models have shown applications in various fields such as biology, economics, and social science. Over the years, multiple agent-based modeling frameworks have been produced, allowing experts with non-computing background to easily write and simulate their models. However, most of these models are limited by the capability of the framework, the time it takes for a simulation to finish, or how to handle the massive amounts of data produced. FLAME (Flexible Large-scale Agent-based Modeling Environment) was produced and developed through the years to address these issues. This book contains a comprehensive summary of the field, covers the basics of FLAME, and shows how concepts of X-machines, can be stretched across multiple fields to produce agent models. It has been written with several audiences in mind. First, it is organized as a collection of models, with detailed descriptions of how models can be designed, especially for beginners. A number of theoretical aspects of software engineering and how they relate to agent-based models are discussed for students interested in software engineering and parallel computing. Finally, it is intended as a guide to developers from biology, economics, and social science, who want to explore how to write agent-based models for their research area. By working through the model examples provided, anyone should be able to design and build agent-based models and deploy them. With FLAME, they can easily increase the agent number and run models on parallel computers, in order to save on simulation complexity and waiting time for results. Because the field is so large and active, the book does not aim to cover all aspects of agent-based modeling and its research challenges. The models are presented to show researchers how they can build complex agent functions for their models. The book demonstrates the advantage of using agent-based models in simulation experiments, providing a case to move away from differential equations and build more reliable, close to real, models.

You Started Your Blog: Now What...?
by Gundi Gabrielle<p>PLEASE NOTE: This book is written for COMPLETE BEGINNERS. <p>Those that have just set up their first blog and are now struggling with the next steps and where to go from here. It was written in response to feedback I received from my first book, which teaches the technical set up to complete beginners. I noticed patterns of what people were struggling with - often just even deciding what topic to focus on - and how blogging works in general. <p>This book will take you by the hand and guide you through the next steps - the solid, basic techniques that every successful blogger started with. There is no magic pill to suddenly attract thousands of followers - although there are a few techniques that can speed things up and we will cover them. Another area that is often underestimated is learning the WRITING STYLE OF BLOGGING, including how to format your posts.T his book goes into detail and provides resources for further training as that is obviously not something you will learn overnight. <p>We will also look at the characteristics of Viral blog posts, but - once again - don't expect a magic pill! Blogging is hard work and becoming a good blogger - a good blog writer - takes training and time, even if you are already experienced in writing. People read blogs differently than books and unless you adjust to that, you will have a hard time attracting an audience - no matter how experienced a writer you are. Finally, we wil go over the basic monetization strategies that are available to bloggers. <p>If you are new to blogging and are willing to put in the necessary work - and do so consistently - this book will give you a good basic start and take out much of the confusion new bloggers face. Of course, blogging also involves the powerful marketing techniques of SEO and Social Media and they are discussed in depth in part 3 and 4 of this series. I have personally found Kindle Publishing to be another great way to grow a blog following quickly - faster than any other technique actually - and so it is included as part 5 of this series. <p>Once again - if you are looking for advanced techniques, this book will not be for you - it is specifically aimed at beginners who have just started their first blog.</p>

Zero Trust Networks: Building Secure Systems in Untrusted Networks
by Doug Barth Evan GilmanThe perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it.The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility.Understand how perimeter-based defenses have evolved to become the broken model we use todayExplore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty)Get example configuration for open source tools that you can use to build a zero trust networkLearn how to migrate from a perimeter-based network to a zero trust network in production

Forewords by Patrick Debois (Founder of devopsdays) and Dr. Donald F. Ferguson (Columbia University).Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the TechnologyThere's a shift underway toward serverless cloud architectures. With the release of serverless computer technologies such as AWS Lambda, developers are now building entirely serverless platforms at scale. In these new architectures, traditional back-end servers are replaced with cloud functions acting as discrete single-purpose services. By composing and combining these serverless cloud functions together in a loose orchestration and adopting useful third-party services, developers can create powerful yet easy-to-understand applications.About the BookServerless Architectures on AWS teaches you how to build, secure, and manage serverless architectures that can power the most demanding web and mobile apps. You'll get going quickly with this book's ready-made real-world examples, code snippets, diagrams, and descriptions of architectures that can be readily applied. By the end, you'll be able to architect and build your own serverless applications on AWS.What's InsideFirst steps with serverless computingImportant patterns and architecturesWriting AWS Lambda functions and using the API GatewayComposing serverless applications using key services like Auth0 and FirebaseSecuring, deploying, and managing serverless architecturesAbout the ReaderThis book is for software developers interested in back end technologies.

掌握比特币-开始赚取比特币的指导: New Moon (Vampyre Ser.)
by Adidas Wilson 顺宏比特币是由名不副实的程序员或者一群程序员发明的一种加密货币和数字支付系统，名叫Satoshi Nakamoto。 它在2009年作为开源软件发布。 系统是点对点的，交易是直接在用户之间进行的，没有中间人。 这些交易由网络节点验证，并记录在称为区块链的公共分布式账本中。 由于该系统没有中央存储库或单个管理员，比特币被称为第一个分散数字货币。 比特币除了被创造为挖矿的奖励外，还可以在合法或黑市交换其他货币，产品和服务。 截至2015年2月，超过10万商户和供应商接受比特币作为付款。 根据剑桥大学2017年的研究报告，使用加密货币钱包的用户数量达到2.9-580万，其中大部分使用比特币。
