New Ways to Build Rich Internet Applications

Ajax has become a popular open approach for developing rich Internet applications. Now, some vendors are releasing their own Ajax-based development platforms, while others have released proprietary platforms not based on Ajax.

Virtualization Sparks Security Concerns

Virtualization is becoming increasingly popular because it helps organizations optimize their hardware utilization. However, the technology has raised numerous security concerns.

News Briefs

Topics include a technology that enables handheld devices to show holographic images, chips that exchange a small loss in precision for a big gain in power efficiency, privacy concerns about technology that lets advertisers measure the viewership of billboards and other public displays, and a nanosoccer tournament for tiny robots.

Cybersecurity Strategies: The QuERIES Methodology

QuERIES offers a novel multidisciplinary approach to quantifying risk associated with security technologies resulting in investment-efficient cybersecurity strategies.

High-Assurance Service-Oriented Architectures

Assuring multiple quality attributes, such as reliability, availability, performance, security, and real-time response, for a variety of critical applications makes it essential to develop practical techniques for implementing high-assurance service-oriented systems.

CROWN-C: A High-Assurance Service-Oriented Grid Middleware System

A proposed grid middleware system includes specific enhancements to support the development and assessment of highly secure, dependable, service-oriented grid systems and applications.

On Testing and Evaluating Service-Oriented Software

As service-oriented architecture matures and more Web services become available, developers must test an ever-increasing volume of services. A framework that defines and evaluates test-case potency based on coverage relationships can reduce testing effort while maintaining testing's effectiveness.

QoS-Reconfigurable Web Services and Compositions for High-Assurance Systems

A service-oriented architecture (SOA) is an ideal vehicle for achieving reconfigurable systems that can select and compose services statically or dynamically to satisfy changing system requirements. The authors have developed a rule-based parameterization technique to convert components into reconfigurable services.

Assuring Timeliness in an e-Science Service-Oriented Architecture

An improvement to public-resource e-science portals shows promise in solving a well-known dilemma: how to dynamically discover a provider PC that is ready to deliver computing power when the scientific community requires it.

Specifying High-Assurance Services

An enhanced approach to service specification strikes a better balance between machine processibility and human readability, and emphasizes testing- as well as reasoning-based assurance techniques. Built-in tests check the compatibility of interacting services at runtime and automatically pinpoint contract mismatches.

IEEE President-Elect Candidates Address Computer Society Concerns

The two candidates for IEEE president-elect in 2009 answer questions identified by Computer Society volunteer leaders as essential to the Computer Society, the IEEE, and the Computer Society's relationship with the IEEE.

Computer Society Connection

Topics covered include the presentation of the 2008 Eckert-Mauchly Award to David Patterson, the awarding of the Taylor L. Booth award to Alan Clements, and two college scholarships sponsored by the Computer Society.
