Book Description
While geographic redundancy can obviously be a huge benefit for disaster recovery, it is far less obvious what benefit is feasible and likely for more typical non-catastrophic hardware, software, and human failures. Georedundancy and Service Availability provides both a theoretical and practical treatment of the feasible and likely benefits of geographic redundancy for both service availability and service reliability. The text provides network/system planners, IS/IT operations folks, system architects, system engineers, developers, testers, and other industry practitioners with a general discussion about the capital expense/operating expense tradeoff that frames system redundancy and georedundancy.

Book Description
We're losing tens of billions of dollars a year on broken software, and great new ideas such as agile development and Scrum don't always pay off. But there's hope. The nine software development practices in Beyond Legacy Code are designed to solve the problems facing our industry. Discover why these practices work, not just how they work, and dramatically increase the quality and maintainability of any software project. These nine practices could save the software industry. Beyond Legacy Code is filled with practical, hands-on advice and a common-sense exploration of why technical practices such as refactoring and test-first development are critical to building maintainable software. Discover how to avoid the pitfalls teams encounter when adopting these practices, and how to dramatically reduce the risk associated with building software--realizing significant savings in both the short and long term. With a deeper understanding of the principles behind the practices, you'll build software that's easier and less costly to maintain and extend. By adopting these nine key technical practices, you'll learn to say what, why, and for whom before how; build in small batches; integrate continuously; collaborate; create CLEAN code; write the test first; specify behaviors with tests; implement the design last; and refactor legacy code. Software developers will find hands-on, pragmatic advice for writing higher quality, more maintainable, and bug-free code. Managers, customers, and product owners will gain deeper insight into vital processes. By moving beyond the old-fashioned procedural thinking of the Industrial Revolution, and working together to embrace standards and practices that will advance software development, we can turn the legacy code crisis into a true Information Revolution.

Book Description
Explanations are important to us in many contexts: in science, mathematics, philosophy, and also in everyday and juridical contexts. But what is an explanation? In the philosophical study of explanation, there is long-standing, influential tradition that links explanation intimately to causation: we often explain by providing accurate information about the causes of the phenomenon to be explained. Such causal accounts have been the received view of the nature of explanation, particularly in philosophy of science, since the 1980s. However, philosophers have recently begun to break with this causal tradition by shifting their focus to kinds of explanation that do not turn on causal information. The increasing recognition of the importance of such non-causal explanations in the sciences and elsewhere raises pressing questions for philosophers of explanation. What is the nature of non-causal explanations - and which theory best captures it? How do non-causal explanations relate to causal ones? How are non-causal explanations in the sciences related to those in mathematics and metaphysics? This volume of new essays explores answers to these and other questions at the heart of contemporary philosophy of explanation. The essays address these questions from a variety of perspectives, including general accounts of non-causal and causal explanations, as well as a wide range of detailed case studies of non-causal explanations from the sciences, mathematics, and metaphysics.

Book Description
This book is the English edition of what has become widely known as 'The Supiot Report' - a bold and far-reaching look at the changing nature of work initiated by the EC. It takes as its starting point the profound changes that have taken place in the underlying employment relationship and associated human resource practices over the past twenty years. These developments are placed in their economic, social, institutional, and legal contexts. Competitive pressures on firms, the search for greater efficiency and effectiveness in the delivery of public services, the changing role of women in society, and the desire for greater choice on the part of individuals are all important motives for change. The legal framework and the structures and organizations which represent the interests of workers and employers must respond to these changes. Drawing on illustrations from a number of European countries, the book suggests that the legal framework should encourage greater collaboration in the workplace, particularly over issues such as training. But it should also place work within its social context and facilitate genuine choices by individuals.

Book Description
Noise is so often a 'stench in the ear' – an unpleasant disturbance or an unwelcome distraction. But there is much more to noise than what greets the ear as unwanted sound. Beyond Unwanted Sound is about noise and how we talk about it. Weaving together affect theory with cybernetics, media histories, acoustic ecology, geo-politics, sonic art practices and a range of noises, Marie Thompson critiques both the conservative politics of silence and transgressive poetics of noise music, each of which position noise as a negative phenomenon. Beyond Unwanted Sound instead aims to account for a broader spectrum of noise, ranging from the exceptional to the banal; the overwhelming to the inaudible; and the destructive to the generative. What connects these various and variable manifestations of noise is not negativity but affectivity. Building on the Spinozist assertion that to exist is to be affected, Beyond Unwanted Sound asserts that to exist is to be affected by noise.

Book Description
In 1999-2000, VoIP (Voice-over-IP) telephony was one of the most successful buzzwords of the telecom bubble era. However, in 2001-2003, VoIP faced a very tough reality check. Now, manufacturers and service providers are drawing on what they have learnt from past experience in order to prepare to participate in the next major challenge faced by the telecommunications industry. This book offers a comprehensive overview of the issues to solve in order to deploy global revenue-generating effective "multimedia" services. Drawing on extensive research and practical deployment experience in VoIP, the authors provide essential advice for those seeking to design and implement a post-bubble VoIP network. Beyond VoIP Protocols: Understanding Voice Technology and Networking Techniques for IP Telephony Introduces the basics of speech coding and voice quality Demonstrates how quality of service may be built into the network and deals with dimensioning aspects, e.g. multipoint communications and how to model call seizures. Explores the potential of multicast to turn an IP backbone into an optimized broadcast medium Includes amply illustrated, state-of-the-art practical advice for formulating a complete deployment strategy A companion volume to "IP Telephony: Deploying VoIP Protocols", this book takes the reader a stage deeper into how to prepare the network and exploit VoIP technology to its full potential.

Book Description
The Eucharist has become the central act of Christian life and worship. Unresolved disagreements about it, however, remain as obstacles to religious unity, and to developing a eucharistic spirituality adapted to the unpredictable standards of a deconstructed, critically driven, postmodern age. Beginning with a reassessment of medieval "realist" doctrines of the Eucharist, Beyond the Body argues that the real meaning of the Words of Institution is their use in fulfilling the Last Supper command of Jesus to be remembered. Where traditional doctrines of the Eucharist and their corresponding forms of piety dead-end in intellectual conundrum or disembodied symbolism, that command evokes a world of transformative events with the historical Jesus of the Last Supper as real and constant partner. As an "antitheology" the task of this book is to sketch the intellectual footprint of a nonmetaphysical eucharistic faith. Setting aside traditional approaches, however, will have been worth it only if this enables a eucharistic belief that meets the needs of and is fruitful for religious life in general. Its ultimate goal is to refocus eucharistic piety on the liturgical act itself as a transformative event united in time with the person of Jesus in both remembrance and thanksgiving.
