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 . . . !

• Cell Broadband Engine Resource Center — The Cell Broadband Engine (CBE) is a new architecture which extends the 64-bit Power Architecture. Ideal for compute-intensive tasks like gaming, multimedia, and physics- or life-sciences and related workloads, the CBE is a single-chip multiprocessor no bigger than a fingernail, with nine processors operating on a shared, coherent memory. This developerWorks page gathers all the relevant resources for the new processor in one place. You'll find fresh articles on the technology, interviews with the movers and the shakers in the Cell world, plus daily news on the processor and links to CBEA forums.
• Digital Rights Management: When a Standard Isn't — In this Standards and specs, Peter shines light on a potential oxymoron — standards designed to subvert and prevent interoperability. DRM: what it is, why you should avoid it, and how you should use it when you have to.
• AJAX with Direct Web Remoting — In the simplest terms, DWR is an engine that exposes methods of server-side Java objects to JavaScript code. Effectively, with DWR, you can eliminate all of the machinery of the Ajax request-response cycle from your application code. This article shows you how to use Direct Web Remoting (DWR) to expose JavaBeans methods directly to your JavaScript code and automate the heavy-lifting of Ajax.
• AJAX and scripting Web services with E4X — E4X is an extension of JavaScript that adds direct support for XML to the language. So what is direct support and why is it valuable? Get an introduction to ECMAScript for XML (E4X), a simple extension to JavaScript that makes XML scripting very simple.
• Fast apps with Workplace Managed Client Developer Toolkit — The Workplace Managed Client Developer Toolkit is a set of plug-ins for Eclipse 3.01 or later. It provides wizards, navigators, builders, and other tools for developers who want to develop, test, and deploy applications quickly. This article walks you through the process of creating a basic application with the Workplace Managed Client Developer Toolkit.
• LPI Exam 202: Network Configuration — developerWorks has published the first in a new series of Linux Professional Institute tutorials. In this tutorial (free login required), David Mertz discusses intermediate network administration on Linux, and in doing so, continues preparing you to take the (LPIC-2) Exam 202. You learn how to configure a basic TCP/IP network, from the hardware layer (usually Ethernet, modem, ISDN, or 802.11) through the routing of network addresses.
• Secrets of lightweight development with Seaside — The Seaside framework is built on the Squeak dialect of Smalltalk and developers the world over recognize Seaside as the top existing continuation server, but Seaside does much more than continuations. This article shows you how to be more productive, and how to be a better, faster, lighter developer with Seaside.
• Build extra secure Web applications — Data received from the client needs further scrutiny to extend the security perimeter from common design elements to application code. To satisfy this requirement, This article offers a new security design framework that covers two common types of vulnerability: action tampering and parameter manipulation (also known as data tampering).
• Develop Sarbanes-Oxley Web services — Want to develop Sarbanes-Oxley (SOX) Web services using IBM DB2 CommonStore? Judith M. Myerson demonstrates how to resolve problems that the SOX mandates have created for executives, now faced with heavy penalties for noncompliance on message and record retention. Follow along with an example of how to resolve the problem by developing or modifying Web services rather than by making changes to a long-running application.
