    Distributed computing, in which an application runs over multiple independent computing nodes, has a higher risk of one or more nodes failing than a centralized, single-node environment. On the other hand, distributed computing can also make an overall system more dependable by detecting those faulty nodes - whether they're due to an underlying hardware or software failure or to compromised security through malicious attacks and then redistributing application components or coordinating them via predefined protocols to avoid such problems. So, traditional dependability studies focus on fault detection, protocols for redistributing application components and coordinating them across nodes, and even failure estimation using system and component characterization.

    The Intelligent Accountability Middleware Architecture (Llama) project supports dependable service-oriented architecture (SOA) monitoring, runtime diagnosis, and reconfiguration. At its core, Llama implements an accountability service bus that users can install on existing service-deployment infrastructures. It collects and monitors service execution data from a key subset of services; enables Llama users to incorporate others' advanced diagnosis models and algorithms into the framework; and provides enterprise service bus extensions for collecting service profiling data, thus making process problems transparent to diagnose. Finally, experimental results indicate that using Llama contributes a modest amount of system overhead. View full abstract»

    Service integration is an important issue in service-oriented computing. As an infrastructure for service-oriented architectures, the enterprise service bus (ESB) has been regarded as a promising way to support dynamic and agile service integration in distributed heterogeneous environments. The authors' ESB framework for large-scale service integration, JTangSynergy, adopts several mechanisms for providing effective and efficient dependability. It enables automated recovery from component failures and robust execution of composite services by checking service compatibility. The authors tested JTangSynergy in the Chinese Healthcare Service Integration project. View full abstract»

    The asynchronous learning networks participatory examination (APE) is a constructivist approach that fully engages students in the entire exam life cycle. Students design and solve exam questions while evaluating their peers' solutions using an anonymous, structured process enabled by Internet technologies. APE achieves higher-level learning by encouraging students to tap into all levels of cognitive skills. Compared to the traditional exam experiences in most classes, most students prefer APE, enjoy its process, and recommend its use. APE liberates both students and instructors by reengineering the examination process and deepening learning throughout. View full abstract»

    Content authors are increasingly using the Internet to network, providing each other with advice, collaboratively filtering important information, and creating virtual networks of trust. To adequately understand this social cyberspace, we must be able to search and explore the patterns and processes of group interaction. A novel software-based approach addresses this objective. The method is built on the concepts of social translucency and social network analysis, extending the latter by including keyword analysis, dynamic network visualization, and additional modeling properties. On the basis of these models, the authors suggest a visualization-based procedure for searching and exploring social corpora using combinable filtering algorithms. They offer two examples-an electronic discussion and a corporate email network-to demonstrate search and retrieval in networks. Their examples further yield novel insights into the actual dynamics of content dissemination and network evolvement among virtual network members. View full abstract»

    The mobile Web's widespread diffusion opens many interesting design and management issues about server infrastructures that must satisfy present and future client demand. Future mobile Web-based services will have growing computational costs. Even requests for the same Web resource will require services to dynamically generate content that takes into account specific devices, user profiles, and contexts. The authors consider the evolution of the mobile Web workload and trends in server and client devices with the goal of anticipating future bottlenecks and developing management strategies.

    For many years, when we used a word-processing application, files were stored in a format that was fully understood only by the application we used. WordPerfect stored WordPerfect files, Microsoft Word stored Word files, and so on-and, while developers often included ad-hoc support for their competitors' formats, that was a hit-and-miss thing, vulnerable to changes in the proprietary formats. The same went for presentation slides and spreadsheets. We all have experience with the results of this, with the difficulties in exchanging files between different applications. OpenDocument format (ODF) is an XML-based open standard file format for office documents such as these. ODF is application-, platform- and vendor-neutral, and thereby facilitates broad interoperability of office documents. View full abstract»

    Service mashups can be useful in understanding Web-scale workflows. Although creating a service mashup shares similar challenges with data integration, a more exciting aspect of this area is the ability to predict which services are viable candidates for a mashup. Such "service mashup recommendations" can enable knowledge discovery, an approach the author calls knowledge discovery in services (KDS). View full abstract»

    After having just written two columns about identity, I'd like to change course by writing about ... identity. But there's a difference: my previous columns dealt mostly with how information available about us on the Internet has evolved in recent years. Here, I want to think a little more deeply about the methods we use to identify ourselves on the Internet - how we do it now, what's wrong with the current approach, and where this notion of identification might go in the future.

  • Welcome to "The Functional Web"

    For me, this magazine issue completes a transition I began two years ago. The previous issue marked the end of the seventh year of the "Toward Integration" column, in which I wrote about issues related to middleware and enterprise integration. One of the points I frequently tried to drive home in that column is that change is inevitable and that it's generally better to embrace it rather than futilely try to prevent it. The transition I'm referring to started when I chose to leave the middleware industry after 16 years. At that point, I initiated the task of refocusing "Toward Integration" toward the Web, which I see as a far more capable, flexible, and cost-effective approach than traditional enterprise middleware for many integration and distribution projects. With this issue, we bid a final farewell to "Toward Integration" and with it, the final vestiges of my focus on the world of enterprise middleware and say hello to "The Functional Web." In this column, I intend to continue writing about Representational State Transfer (REST) and the Web, specifically concentrating on developing production-ready RESTful Web services using functional programming (FP) languages and techniques.
