Whether you want to automate tasks, analyze data, parse logs, talk to network services, or address other systems requirements, writing your own command-line tool may be the fastest - and perhaps the most fun - way to do it. The Go programming language is a great choice for developing tools that are fast, reliable, and cross-platform. Create command-line tools that work with files, connect to services, and even manage external processes, all while using tests and benchmarks to ensure your programs are fast and correct. When you want to develop cross platform command-line tools that are fast and reliable, use Go, a modern programming language that combines the reliability of compiled languages with the ease of use and flexibility of dynamic typed languages. Work through practical examples to develop elegant and efficient tools by applying Go's rich standard library, its built in support for concurrency, and its expressive syntax. Use Go's integrated testing capabilities to automatically test your tools, ensuring they work reliably even across code refactoring. Develop CLI tools that interact with your users by using common input/output patterns, including environment variables and flags. Handle files to read or persist data, and manipulate paths consistently in cross-platform scenarios. Control processes and handle signals, and use a benchmark driven approach and Go's concurrency primitives to create tools that perform well. Use powerful external libraries such as Cobra to create modern and flexible tools that handle subcommands, and develop tools that interact with databases, APIs, and network services. Finally, leverage what you learned by tackling additional challenges at the end of each chapter. What You Need: Go 1.8 or higher, an internet connection to download the example files and additional libraries, and a text editor to write your programs.

This book offers a unique approach to taking the design and analyses to the level of predictable practical efficiency, discussing core and classic algorithmic problems that arise in the development of big data applications, and presenting elegant solutions of increasing sophistication and efficiency. Solutions are analyzed within the classic RAM model, and the more practically significant external-memory model that allows one to perform I/O-complexity evaluations. Chapters cover various data types, including integers, strings, trees, and graphs, algorithmic tools such as sampling, sorting, data compression, and searching in dictionaries and texts, and lastly, recent developments regarding compressed data structures. Algorithmic solutions are accompanied by detailed pseudocode and many running examples, thus enriching the toolboxes of students, researchers, and professionals interested in effective and efficient processing of big data.

This book offers a mathematical foundation for modern cryptography. It is primarily intended as an introduction for graduate students. Readers should have basic knowledge of probability theory, but familiarity with computational complexity is not required. Starting from Shannon's classic result on secret key cryptography, fundamental topics of cryptography, such as secret key agreement, authentication, secret sharing, and secure computation, are covered. Particular attention is drawn to how correlated randomness can be used to construct cryptographic primitives. To evaluate the efficiency of such constructions, information-theoretic tools, such as smooth min/max entropies and information spectrum, are developed. The broad coverage means the book will also be useful to experts as well as students in cryptography as a reference for information-theoretic concepts and tools.

Since the late 1990s, Information and Communication Technologies (ICTs) have been hailed as a potentially revolutionary feature of the planning and management of Western cities. Economic regeneration and place promotion strategies have exploited these new technologies; city management has experimented with electronically distributed services, and participation in public life and democratic decision-making processes can be made more flexible by the use of ICTs. All of these technological initiatives have often been presented and accessed via an urban front-end information site known as 'digital city' or 'city network.' Illustrated by a range of European case studies, this volume examines the social, political and management issues and potential problems in the establishment of an electronic layer of information and services in cities. The book provides a better understanding of the direction European cities are going towards in the implementation of ICTs in the urban arena.

NEW YORK TIMES AND SUNDAY TIMES BUSINESS BESTSELLER SHORTLISTED FOR THE FT AND MCKINSEY BUSINESS BOOK OF THE YEAR AWARD 2019 'Reads more like a delicious page-turning novel...Put it on your holiday gift list for your favourite hedge-fund honcho' Bloomberg 'A compelling read' Economist 'Captivating' New York Times book review Jim Simons is the greatest moneymaker in modern financial history. His record bests those of legendary investors, including Warren Buffett, George Soros and Ray Dalio. Yet Simons and his strategies are shrouded in mystery. The financial industry has long craved a look inside Simons's secretive hedge fund, Renaissance Technologies and veteran Wall Street Journal reporter Gregory Zuckerman delivers the goods. After a legendary career as a mathematician and a stint breaking Soviet codes, Simons set out to conquer financial markets with a radical approach. Simons hired physicists, mathematicians and computer scientists - most of whom knew little about finance - to amass piles of data and build algorithms hunting for the deeply hidden patterns in global markets. Experts scoffed, but Simons and his colleagues became some of the richest in the world, their strategy of creating mathematical models and crunching data embraced by almost every industry today. As Renaissance became a major player in the financial world, its executives began exerting influence on other areas. Simons became a major force in scientific research, education and Democratic politics, funding Hilary Clinton's presidential campaign. While senior executive Robert Mercer is more responsible than anyone else for the Trump presidency - he placed Steve Bannon in the campaign, funded Trump's victorious 2016 effort and backed alt-right publication Breitbart. Mercer also impacted the success of the Brexit campaign as he made significant investments in Cambridge Anatlytica. For all his prescience, Simons failed to anticipate how Mercer's activity would impact his firm and the world. In this fast-paced narrative, Zuckerman examines how Simons launched a quantitative revolution on Wall Street, and reveals the impact that Simons, the quiet billionaire king of the quants, has had on worlds well beyond finance.

The authors bring a dual perspective--that of a practicing consultant and that of a professor of economics--to the complex strategic questions facing managers and corporate leaders who want their firms to get the most out of their investments in information technology. The information economy is built upon the myriad and sometimes unforeseen ways in which information technologies have become engines of productivity in themselves, rather than just fancy adjuncts. In explaining the rise of the information economy, the authors provide not only valuable context often missing from today's discussions but also a thorough understanding of the origination, development, and diffusion process of innovations. They also examine prevailing practices and implications for the future, including the potential pitfalls common to some information technology strategies. Relying on an underpinning of economic theory combined with heavy empirical analysis, Kudyba and Diwan describe the true nature of the information economy, paying as much attention to its particularities as to its more profound implications. How is information technology being implemented across industry sectors, and how can it be harnessed to improve overall firm-level productivity? How have innovations in high technology impacted e-commerce? Which e-commerce strategies prevail, and what can be expected of them? How can traditional economic theory help managers evaluate such in-vogue strategies as customer relationship management, market exchanges, and supply chain management? The authors answer these questions and more, including one of the most vexing in the short history of e-commerce: What led to the demise of so many technology stocksand dot-coms following the spring 2000 Nasdaq plunge, and what are the longer-term prospects for e-business?

In this stimulating analysis, Hannes Gerhardt outlines the potentials and challenges of a technology-enabled, commons-focused transition out of capitalism. The book shows that openness and cooperation are more beneficial in today’s economies and societies than competition and profit-seeking. Driven by this conviction, Gerhardt identifies key imperatives for overcoming capitalism, from democratizing our digital, material, and financial economies to maintaining a robust, political mobilization. Using clear examples, he explores tactical openings through the lens of ‘compeerism’, a newly constructed framework that highlights the latent counter-capitalist possibilities, but also limits, of our emerging technological landscape. This is an accessible contribution to counter-capitalist discourse that is both inspiring and pragmatic for academics and activists alike.

A collection of essays by over 40 experts, including leading writers Charles Handy and Don Tapscott, giving their personal vision of the future of information. Information here is given its widest meaning and includes such subjects as the Internet, electronic commerce, cybernetics, robotics, artificial intelligence, and even computers as fashion accessories. Information as a phenomenon pervades all areas of life and its evolution has consequences for everyone. Many of the papers have central themes such as the future of computer intelligence, library and information services, interactive Internet marketing, and networked learning in higher education. One paper links the technology enabling remote and online communication to the deconstruction of the corporation and the rise of flexible working. Professor Kevin Warwick writes about cybernetics and artificial intelligence, and describes an experiment involving a surgically implanted computer chip in his arm. Other papers deal with scholarly communication, smart houses and intelligent appliances. Two of the chapters are written as fiction, one by contemporary fantasy writer, Lise Leroux, who paints a menacing vision of human error in

In 2012, the United Nations General Assembly determined that affordable Internet access is a human right, critical to citizen participation in democratic governments. Given the significance of information and communication technologies (ICTs) to social and political life, many U.S. tribes and Native organizations have created their own projects, from streaming radio to building networks to telecommunications advocacy. In Network Sovereignty, Marisa Duarte examines these ICT projects to explore the significance of information flows and information systems to Native sovereignty, and toward self-governance, self-determination, and decolonization. By reframing how tribes and Native organizations harness these technologies as a means to overcome colonial disconnections, Network Sovereignty shifts the discussion of information and communication technologies in Native communities from one of exploitation to one of Indigenous possibility.
