IBM has published the following technical articles, tutorials, and downloads on its DeveloperWorks website. They cover a range of interesting (though not necessarily embedded) technical topics, primarily related to Linux and open source system development. Some require free registration. Enjoy . . . !

• The Pitfalls and Perks of Adopting a New Standard — Whether a standard will succeed and be widely adopted is ambiguous at first, regardless of who endorses it — a major player or a fringe element. So if most people don't like to welcome the new guy, why would they put all their eggs in a standards basket when that basket might not exist tomorrow? Join Peter Seebach as he shows the potential advantages/disadvantages of adopting a standard before it becomes one.
• The More Processors, the Better — Achieve a level of high reliability in a microprocessor system by adding a second identical processor to a system to monitor and verify the system processor operation — also known as the lockstep processor technique. This tip demonstrates the integrated lockstep facility (LSF) in the PowerPC 750GX processor.
• Cell Broadband Processor Debut in Blade Servers — Who offers 2.5 teraflops (and more) in exchange for just 7U of rack space? You'll find the answer (Cell! Blades!) to this and all the rest of the Power Architecture news that's fit to print in our fortnightly calendar.
• Support Bulletins for Clustering and AIX in Your Inbox — Get CSM and AIX support bulletin updates as they're published. Available downloads include JS20 BladeCenter on PowerPC 970 tuning tips, the PowerPC 405 Evaluation Kit, and a utility to power and frequency scale the PowerPC 970. Plus loads on Blue Gene and z/OS!
• Using the Ruby Development Tools plug-in for Eclipse — Ruby is a single inheritance language, but it offers some advanced features that Java technology does not, such as closures (think anonymous inner classes on steroids) and mix-ins. This article introduces using the Ruby Development Tools (RDT) plug-in for Eclipse, which allows Eclipse to become a first-rate Ruby development environment. Ruby developers who want to learn how to use the rich infrastructure of the Eclipse community to support their language will benefit, as will Java developers who are interested in using Ruby.
• Java generics support in Eclipse V3.1 — The generics support in the Java programming language is the most significant syntax change in its history. This article highlights how Eclipse has responded and the changes wrought by generics to the Java language. It shows how to take full advantage of generics within Eclipse, including support in Quick Assist, Quick Fix, refactoring, and project preferences. It also shows some subtle and important aspects of a fully generic language.
• Best performance practices for SDO and the JDBC DMS — This article shows you how to obtain the best performance from SDO and the JDBC DMS, by keep your metadata models as small as possible, ensuring that the most efficient SQL queries are being used, and by using static SDO models whenever possible.
• Maximize Your Grid Potential — IBM's developerWorks has just released the last of a three-part series designed to help you make better use of the grid resources available. Part 1 discusses the Ganglia tool kit to enhance the information services already present in the Globus environment. Part 2 covers meta-schedulers, or brokers, which take that data and make it easier to select the most appropriate and efficient resource for your job. Finally, part 3 focuses on security and how to use available security tools.
• The advantages of SOA — Listen at your leisure to The advantages of SOA podcast, an informative interview with Matthew Oberlin, who is an expert in service-oriented architecture (SOA) implementation. He will discuss SOA being evolutionary, not revolutionary – it's really about business activities being reusable, building SOA components for the SOA programming model and the main elements of the SOA environment. The podcast provides insight into the fundamental principles behind the SOA programming model.
• Clean up your web apps with SOAP and AJAX — Popularized through its use in a number of well-known Web application services like GMail, Google Maps, Flickr, and Odeo.com, AJAX provides Web developers with a way of expanding the value and function of their Web applications by using asynchronous XML messaging. This article shows you how to implement a Web browser-based SOAP Web services client using the Asynchronous JavaScript and XML (AJAX) design pattern.
• Learn how to use Ajax with PHP, and meet Sajax — For years, the goal of creating a truly responsive Web application was hampered by one simple fact of Web development: To change the information on part of a page, a user must reload the entire page. Not anymore. Thanks to asynchronous JavaScript and XML (Ajax), we can now request new content from the server and change just part of a page. This tutorial explains how to use Ajax with PHP and introduces Sajax (Simple Ajax Toolkit), a tool written in PHP that lets you integrate server-side PHP with JavaScript.
• Atom allows your web service to be seen — Finaly we have a simple means of discovering when new services had been made available at a particular endpoint location. This article introduce and demonstrate the combined use of the Atom 1.0 and Web Services Addressing 1.0 specifications as a functional replacement for the now defunct WS-Inspection.
