This article investigates and compares different design patterns of high performance TCP-based servers. In addition to existing approaches, it proposes a scalable single-codebase, multi-platform solution (with code examples) and describes its fine-tuning on different platforms. It also compares performance of Java, C# and C++ implementations of proposed and existing solutions.

Any reasonably complex end-user application is going to require some sort of customization and enhancement for effective deployment. This article shows one way to create a modular architecture as a way of leaving the door open for advanced users or consultants who want to extend the functionality without modifying the source.

Ruby Queue software package lowers the barriers scientists need to overcome in order to realize the power of Linux clusters. It provides an extremely simple, economic, and easy-to-understand tool that harnesses the power of many CPUs while simultaneously allowing researchers to shift their focus away from the mundane details of complicated distributed computing systems and back to the task of actually doing science. The tool set is designed with a K.I.S.S, research-focused, philosophy that enables any ordinary (non-root) user to set up a zero-admin Linux cluster in 10 minutes or less. It is currently being used successfully in such diverse fields as bio-chemical research at the University of Toronto, geo-mechanical modeling at IGEOSS, and studying the nighttime lights of the world at the National Geophysical Data Center.

The Java Contactless Communication API (JSR 257) enables mobile devices to communicate via short-range wireless means, such as RFID, infrared light, or even Bluetooth, and presents such devices via a simple, homogeneous interface to Java applications. This article explains the role of the Java Contactless Communication API in the emerging field of near-field communications, and provides an example of reading data from any contactless target, including an RFID tag.

The Java Data Mining API (JDM) is the first attempt to create a standard Java API to access data-mining tools from Java applications. JDM promises to bring to data mining what JDBC brought to databases, and to make data mining a new and useful part of an enterprise Java developer's tool chest. This article introduces basic data-mining concepts, and illustrates sample JDM code to model customer behavior.

Java's future hinges as much on leadership as on sound technology. In this article, the spec leads of several JSRs share their insights into the key ingredients of leading a successful design, development, and specification project with a distributed team of experts. Substitute spec lead with project lead, and these lessons are relevant to anyone leading a software development effort.
