Proof of Work: Blockchain Provocations 20112021 (Urbanomic / Art Editions)
by Rhea MyersA beautifully produced anthology of crypto-artist, writer, and hacker Rhea Myers's pioneering blockchain art, along with a selection of her essays, reviews, and fictions.DAO? BTC? NFT? ETH? ART? WTF? HODL as OG crypto-artist, writer, and hacker Rhea Myers searches for faces in cryptographic hashes, follows a day in the life of a young shibe in the year 2032, and patiently explains why all art should be destructively uploaded to the blockchain. Now an acknowledged pioneer whose work has graced the auction room at Sotheby&’s, Myers embarked on her first art projects focusing on blockchain tech in 2011, making her one of the first artists to engage in creative, speculative, and conceptual engagements with "the new internet." Proof of Work brings together annotated presentations of Myers&’s blockchain artworks along with her essays, reviews, and fictions—a sustained critical encounter between the cultures and histories of the artworld and crypto-utopianism, technically accomplished but always generously demystifying and often mischievous. Her deep understanding of the technical history and debates around blockchain technology is complemented by a broader sense of the crypto movement and the artistic and political sensibilities that accompanied its ascendancy. Remodeling the tropes of conceptual art and net.art to explore what blockchain technology reveals about our concepts of value, culture, and currency, Myers&’s work has become required viewing for anyone interested in the future of art, consensus, law, and collectivity.
Proofs and Algorithms
by Gilles DowekLogic is a branch of philosophy, mathematics and computer science. It studies the required methods to determine whether a statement is true, such as reasoning and computation. Proofs and Algorithms: Introduction to Logic and Computability is an introduction to the fundamental concepts of contemporary logic - those of a proof, a computable function, a model and a set. It presents a series of results, both positive and negative, - Church's undecidability theorem, Gödel's incompleteness theorem, the theorem asserting the semi-decidability of provability - that have profoundly changed our vision of reasoning, computation, and finally truth itself. Designed for undergraduate students, this book presents all that philosophers, mathematicians and computer scientists should know about logic.

Property-Based Testing with PropEr, Erlang, and Elixir: Find Bugs Before Your Users Do
by Fred HebertProperty-based testing helps you create better, more solid tests with little code. By using the PropEr framework in both Erlang and Elixir, this book teaches you how to automatically generate test cases, test stateful programs, and change how you design your software for more principled and reliable approaches. You will be able to better explore the problem space, validate the assumptions you make when coming up with program behavior, and expose unexpected weaknesses in your design. PropEr will even show you how to reproduce the bugs it found. With this book, you will be writing efficient property-based tests in no time. Most tests only demonstrate that the code behaves how the developer expected it to behave, and therefore carry the same blind spots as their authors when special conditions or edge cases show up. Learn how to see things differently with property tests written in PropEr. Start with the basics of property tests, such as writing stateless properties, and using the default generators to generate test cases automatically. More importantly, learn how to think in properties. Improve your properties, write custom data generators, and discover what your code can or cannot do. Learn when to use property tests and when to stick with example tests with real-world sample projects. Explore various testing approaches to find the one that's best for your code. Shrink failing test cases to their simpler expression to highlight exactly what breaks in your code, and generate highly relevant data through targeted properties. Uncover the trickiest bugs you can think of with nearly no code at all with two special types of properties based on state transitions and finite state machines. Write Erlang and Elixir properties that generate the most effective tests you'll see, whether they are unit tests or complex integration and system tests. What You Need Basic knowledge of Erlang, optionally ElixirFor Erlang tests: Erlang/OTP >= 20.0, with Rebar >= 3.4.0For Elixir tests: Erlang/OTP >= 20.0, Elixir >= 1.5.0
Proportionate-type Normalized Least Mean Square Algorithms
by Milos Doroslovacki Kevin WagnerThe topic of this book is proportionate-type normalized least mean squares (PtNLMS) adaptive filtering algorithms, which attempt to estimate an unknown impulse response by adaptively giving gains proportionate to an estimate of the impulse response and the current measured error. These algorithms offer low computational complexity and fast convergence times for sparse impulse responses in network and acoustic echo cancellation applications. New PtNLMS algorithms are developed by choosing gains that optimize user-defined criteria, such as mean square error, at all times. PtNLMS algorithms are extended from real-valued signals to complex-valued signals. The computational complexity of the presented algorithms is examined. Contents 1.

Prospective Ergonomics
by André LiemThis book argues for a prospective turn in ergonomics to challenge the established fields of strategic design (SD) and management. Its multi-disciplinary outlook builds upon concepts derived from Management, Innovation and Design Science. Differences, similarities and relationships between strategic design and prospective ergonomics are reviewed using existing theories and frameworks from design, ergonomics, and strategic and innovation management. To complement the theory, 12 cases have been analyzed in greater depth according to 4 main dimensions of analysis. Outcomes have shown that innovating through the Prospective Ergonomics (PE) approach is about finding the right balance between, on the one hand, meeting primary objectives such as profit maximization or solving the design problem, and on the other, acknowledging that human activity is bounded by rationality. This means that humans have diverse motives.
Protecting Children Online?: Cyberbullying Policies of Social Media Companies (The Information Society Series)
by Tijana MilosevicA critical examination of efforts by social media companies—including Facebook, Twitter, Snapchat, and Instagram—to rein in cyberbullying by young users.High-profile cyberbullying cases often trigger exaggerated public concern about children's use of social media. Large companies like Facebook respond by pointing to their existing anti-bullying mechanisms or coordinate with nongovernmental organizations to organize anti-cyberbullying efforts. Do these attempts at self-regulation work? In this book, Tijana Milosevic examines the effectiveness of efforts by social media companies—including Facebook, Twitter, YouTube, Snapchat, and Instagram—to rein in cyberbullying by young users. Milosevic analyzes the anti-bullying policies of fourteen major social media companies, as recorded in companies' corporate documents, draws on interviews with company representatives and e-safety experts, and details the roles of nongovernmental organizations examining their ability to provide critical independent advice. She draws attention to lack of transparency in how companies handle bullying cases, emphasizing the need for a continuous independent evaluation of effectiveness of companies' mechanisms, especially from children's perspective. Milosevic argues that cyberbullying should be viewed in the context of children's rights and as part of the larger social problem of the culture of humiliation.Milosevic looks into five digital bullying cases related to suicides, examining the pressures on the social media companies involved, the nature of the public discussion, and subsequent government regulation that did not necessarily address the problem in a way that benefits children. She emphasizes the need not only for protection but also for participation and empowerment—for finding a way to protect the vulnerable while ensuring the child's right to participate in digital spaces.

Protecting Individual Privacy in the Struggle Against Terrorists: A Framework for Program Assessment
by National Research Council of the National AcademiesAll U.S. agencies with counterterrorism programs that collect or "mine" personal data -- such as phone records or Web sites visited -- should be required to evaluate the programs' effectiveness, lawfulness, and impacts on privacy. A framework is offered that agencies can use to evaluate such information-based programs, both classified and unclassified. The book urges Congress to re-examine existing privacy law to assess how privacy can be protected in current and future programs and recommends that any individuals harmed by violations of privacy be given a meaningful form of redress. Two specific technologies are examined: data mining and behavioral surveillance. Regarding data mining, the book concludes that although these methods have been useful in the private sector for spotting consumer fraud, they are less helpful for counterterrorism because so little is known about what patterns indicate terrorist activity. Regarding behavioral surveillance in a counterterrorist context, the book concludes that although research and development on certain aspects of this topic are warranted, there is no scientific consensus on whether these techniques are ready for operational use at all in counterterrorism.

Protecting National Security: A History of British Communications Investigation Regulation
by Phil GloverThis book contends that modern concerns surrounding the UK State’s investigation of communications (and, more recently, data), whether at rest or in transit, are in fact nothing new. It evidences how, whether using common law, the Royal Prerogative, or statutes to provide a lawful basis for a state practice traceable to at least 1324, the underlying policy rationale has always been that first publicly articulated in Cromwell’s initial Postage Act 1657, namely the protection of British ‘national security’, broadly construed. It further illustrates how developments in communications technology led to Executive assumptions of relevant investigatory powers, administered in conditions of relative secrecy. In demonstrating the key role played throughout history by communications service providers, the book also charts how the evolution of the UK Intelligence Community, entry into the ‘UKUSA’ communications intelligence-sharing agreement 1946, and intelligence community advocacy all significantly influenced the era of arguably disingenuous statutory governance of communications investigation between 1984 and 2016. The book illustrates how the 2013 ‘Intelligence Shock’ triggered by publication of Edward Snowden’s unauthorized disclosures impelled a transition from Executive secrecy and statutory disingenuousness to a more consultative, candid Executive and a policy of ‘transparent secrecy’, now reflected in the Investigatory Powers Act 2016. What the book ultimately demonstrates is that this latest comprehensive statute, whilst welcome for its candour, represents only the latest manifestation of the British state’s policy of ensuring protection of national security by granting powers enabling investigative access to communications and data, in transit or at rest, irrespective of location.

Protecting Privacy in Data Release
by Giovanni LivragaThis book presents a comprehensive approach to protecting sensitive information when large data collections are released by their owners. It addresses three key requirements of data privacy: the protection of data explicitly released, the protection of information not explicitly released but potentially vulnerable due to a release of other data, and the enforcement of owner-defined access restrictions to the released data. It is also the first book with a complete examination of how to enforce dynamic read and write access authorizations on released data, applicable to the emerging data outsourcing and cloud computing situations. Private companies, public organizations and final users are releasing, sharing, and disseminating their data to take reciprocal advantage of the great benefits of making their data available to others. This book weighs these benefits against the potential privacy risks. A detailed analysis of recent techniques for privacy protection in data release and case studies illustrate crucial scenarios. Protecting Privacy in Data Release targets researchers, professionals and government employees working in security and privacy. Advanced-level students in computer science and electrical engineering will also find this book useful as a secondary text or reference.
