IBM has published the following new 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 . . . !

• DB2 Eclipse-Based Workbench and Stored Procedures — In Part 1 of this series you learned about Developer Workbench concepts and basic tasks. In this article learn how the Eclipse-based Developer Workbench resources, perspectives, views, editors, and wizards assist you to work with stored procedures. DWB is based on Eclipse technology, which replaces the Swing-based DB2 V8 Development Center.
• Learn Eclipse Callisto release GMF in 15 minutes — This article introduces the Graphical Modeling Framework (GMF) project, shows how to develop a simple Eclipse Modeling Framework (EMF) model, and transform it into a full-blown graphical editor using GMF's tooling. This demonstrates one of the most exciting parts of the Eclipse Callisto release that supports model-driven development.
• Choosing the Right Continuous Integration Server — With so many Continuous Integration (CI) servers to choose from, it can be difficult to decide which one is right for you. In the second article of the series Automation for the people, development automation expert Paul Duvall explores a handful of open source CI servers, including Continuum, CruiseControl, and Luntbuild, using a consistent evaluation criteria and illustrative examples.
• NFSv4 Delivers Seamless Network Access — Network File System (NFS) has been part of the world of free operating systems and proprietary UNIX flavors since the mid-1980s. But not all administrators know how it works or why there have been new releases. It is important to know about NFS simply because the system is vital for seamless access across UNIX networks. Learn how the latest release of NFS, NFSv4, has addressed many criticisms, particularly with regard to security problems, that became apparent in versions 2 and 3.
• Backing up key system data is a no-brainer, or is it? — Most UNIX administrators have processes in place to back up the data and information on their UNIX machines, but what about the configuration files and other elements that provide the configuration data your machines need to operate? This article provides detailed information on techniques for achieving an effective and efficient backup system for these key files.
• UNIX Error Reporting in the Standard C Library — Proper error detection and recovery is often ignored by UNIX developers. The lack of exceptions from the C language and the rudimentary error mechanisms from the standard C library certainly contribute to this. This article familiarizes you with the UNIX standard error reporting mechanism, the errno global variable. You'll also learn about a couple of associated global variables (sys_nerr and sys_errlist).
• Improve Mashup performance with pureXML — In Part 1 of the Building the ultimate Mashup series we discussed a Mashup application, which begins to draw data from several services and combines it. Now we will discuss how to save Mashup request results to a DB2 9 database, plus show you how take some of the load off of those external Mashup services and greatly improve performance with pureXML.
• Bridge the gap between XML and Ajax with JSON — A couple of years ago, many developers bet their futures on XML, XSLT, Extensible HTML (XHTML), and a host of tag-based “X” languages. Now, the new rage is Asynchronous JavaScript and XML (AJAX), and investors' eyes are turning toward data-driven Rich Internet Applications that use JavaScript code. But have developers bridged the gap between XML and this new technology? This article helps answer that question with different approaches for using XSLT V2 to generate JavaScript Object Notation (JSON) from XML data for use in Ajax applications.
• Mastering Ajax with DOM-based Web applications — You'll be hard-pressed to do much in the Ajax and JavaScript worlds without using the DOM to at least some degree. Whether you create complex highlighting and movement effects, or just work with text blocks or images, the DOM gives you access to a Web page in a really easy-to-use manner. This article shows you how to build a simple Web page that has some nice effects, all created using JavaScript to manipulate the DOM.
• Zend translates native PHP objects for Ajax tricks — Find out how the Zend Framework makes it easy to add Ajax interactions to your application by automatically translating native PHP objects to and from JavaScript Object Notation (JSON).
