Repair, reuse and disposal are closely interlinked phenomena related to the service lives and persistence of technologies. When technical artefacts become old and worn out, decisions have to be taken: is it necessary, worthwhile or even possible to maintain and repair, reuse or dismantle them - or must they be discarded? These decisions depend on factors such as the availability of second-hand markets, repair infrastructures and dismantling or disposal facilities. In telling the stories of China's power grid, Canadian telephones, German automobiles and India's shipbreaking business, among others, the contributions in this volume highlight the persistence of technologies and show that maintenance and repair are not obsolete in modern industries and consumer societies.

The Definitive Guide to Today’s Leading Persistence Technologies Persistence in the Enterprise is a unique, up-to-date, and objective guide to building the persistence layers of enterprise applications. Drawing on their extensive experience, five leading IBM® Web development experts carefully review the issues and tradeoffs associated with persistence in large-scale, business-critical applications. The authors offer a pragmatic, consistent comparison of each leading framework--both proprietary and open source. Writing for IT managers, architects, administrators, developers, and testers, the authors address a broad spectrum of issues, ranging from coding complexity and flexibility to scalability and licensing. In addition, they demonstrate each framework side by side, via a common example application. With their guidance, you’ll learn how to define your persistence requirements, choose the most appropriate solutions, and build systems that maximize both performance and value. Coverage includes Taking an end-to-end application architecture view of persistence Understanding business drivers, IT requirements, and implementation issues Driving your persistence architecture via functional, nonfunctional, and domain requirements Modeling persistence domains Mapping domain models to relational databases Building a yardstick for comparing persistence frameworks and APIs Selecting the right persistence technologies for your applications Comparing JDBCTM, Apache iBATIS, Hibernate Core, Apache OpenJPA, and pureQuery The companion web site includes sample code that implements the common example used throughout the technology evaluation chapters, 5-9. The IBM Press developerWorks® Series is a unique undertaking in which print books and the Web are mutually supportive. The publications in this series are complemented by resources on the developerWorks Web site on ibm.com. Icons throughout the book alert the reader to these valuable resources.

From everyday apps to complex algorithms, Ruha Benjamin cuts through tech-industry hype to understand how emerging technologies can reinforce White supremacy and deepen social inequity. Benjamin argues that automation, far from being a sinister story of racist programmers scheming on the dark web, has the potential to hide, speed up, and deepen discrimination while appearing neutral and even benevolent when compared to the racism of a previous era. Presenting the concept of the “New Jim Code,” she shows how a range of discriminatory designs encode inequity by explicitly amplifying racial hierarchies; by ignoring but thereby replicating social divisions; or by aiming to fix racial bias but ultimately doing quite the opposite. Moreover, she makes a compelling case for race itself as a kind of technology, designed to stratify and sanctify social injustice in the architecture of everyday life. This illuminating guide provides conceptual tools for decoding tech promises with sociologically informed skepticism. In doing so, it challenges us to question not only the technologies we are sold but also the ones we ourselves manufacture. Visit the book's free Discussion Guide here.

Excerpt from On the Persistence of Researchers in Technological Development Recognizing the benefits of persistence, Ziman (1987) nevertheless cautions against the decreasing marginal returns from undue persistence. According to Chubin and Connolly researchers persisting unduly with an area of work in order to leave a research trail. Over time, this type of behavior leads to incremental yields from a stock of knowledge. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
