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. Some require free registration. Enjoy . . .

• Stress-testing the Linux kernel — Automating software testing allows you to run the same tests over a period of time, ensuring that you are really comparing apples to apples and oranges to oranges. In this article, Linux Test Project team members share their methodology and rationale, as well as the scripts and tools they use to stress-test the Linux kernel.
• Back Up My Linux — The loss of critical data can prove devastating. Still, millions of professionals ignore backing up their data. While individual reasons vary, one of the most common explanations is that performing routine backups can be a real chore. Because machines excel at mundane and repetitive tasks, the key to reducing the inherent drudgery and the natural human tendency for procrastination, is to automate the backup process.
• Five Performance Tools for Linux on PowerPC — This article describes Performance Inspector, which contains a suite of performance tools for Linux. The author describes how to download and install the required software and tools, and how to collect performance data. She also provides details on how to use the five basic tools, which you can use to analyze performance of your C/C++and Java applications, as well as performance of your system as a whole.
• Migrating Win32 C/C++ apps to Linux on POWER — This article covers Win32 API mapping, particularly process, thread, and shared memory services to Linux on POWER. The article can help you decide which of the mapping services best fits your needs. The author takes you through the APIs mapping he faced while porting a Win32 C/C++ application.
• BlueSpace a high-resolution wall display built on the Java platform — The BlueSpace wall display is an exciting demonstration of the potential of multimedia development on the Java platform. The BlueSpace project is a large-scale, high-resolution visual screen that is implemented as a grid of projected computer displays. In this article, you'll learn about some of the code behind the BlueSpace wall display project presented this year at JavaOne.
• Stretch Java skills with CodeRuler medieval game — Guard your castle! Claim your land! Command your knights to joust valiantly and defeat their foes. Capture the enemy's position and seize its land while dodging its menacing knights. If writing mundane Java code is giving you the blues lately, maybe it's time to turn your medieval fantasies into reality with CodeRuler. You can rule your own kingdom while refining your Java programming skills and mastering the Eclipse development environment all at the same time. This article provides you with the Jave tips needed to let you achieve ultimate CodeRuler kingdom domination.
• Jython for Python and Java developers — Jython is an alternate languages for the Java Runtime Environment. Its an implementation of the popular scripting language Python, but running on a JVM. For Python developers Jython is the best possible entry point to the Java platform; for Java developers it may be the strongest incentive to learn another language. This article introduces Jython and shows you what it can do to enhance your productivity on the Java platform.
• Python applied to the Natural Language — This installment introduces you to the Natural Language Toolkit, a Python library for applying academic linguistic techniques to collections of textual data. Programming that goes by the name “text processing” is a start; other capabilities for syntactic and even semantic analysis are further specialized to studying natural languages.
• Existing Applications can be Enabled for Grid — Most enablement efforts, for existing code using batch-oriented grid infrastructure software, are similar. There's a pattern you can follow. You can use this pattern to achieve the first three strategies of grid adoption.
• IBM Brings Grid Computing to Leading Application Developers — IBM today announced that seven leading application software developers, including Citrix, Cognos, and Engineous Software, have completed work with IBM to ready their applications for Grid computing. These companies are targeting what is expected to be a $12 billion Grid market opportunity by 2007.
• Getting Information From Here to There and Back Again — An information grid, as defined by this article, is the structure that allows end users and applications to share information, no matter where it is stored. The article shows system architects how to think through the information infrastructure when setting up a grid computing environment.
• Governments and Large Corporations Choose Linux - Have You? — Live demonstrations include how to use Linux as a file server and how to use Samba and Linux as a platform for Web applications. Rapid Application Development on Linux is demonstrated utilizing WebSphere Studio, which is based on Eclipse, the open source universal tool platform. This briefing also showcases Linux on the desktop. One ThinkPad notebook will be awarded at each developerWorks Live technical briefing being held in New York, Boston, and Colorado in July.
