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.

• What's hot in Eclipse V3.2 Callisto — Eclipse Callisto (V3.2) offers new and improved features over Eclipse V3.1.x and many IDEs available today. Developers who have been using Eclipse V3.1.x will find it easier to get Eclipse up and running to do a variety of tasks, including Java development, Web services development, XML and XSD building, and connecting to and working with databases. This article introduces the new features and improved usability, along with links to many resources on Callisto projects.
• Pointers and memory leaks in C — In this article you'll learn about the types of pointer operations that can cause memory corruption and you'll also examine some scenarios that show what to consider while working with dynamic memory allocation. Pointers and memory leaks might seem to be deterrents to some programmers but, once you understand the fundamentals of pointers and associated memory operations, they will be the most powerful tool you posses in C.
• System Administration Toolkit: Swap space management and tricks — The typical UNIX administrator has a key range of utilities, tricks, and systems he or she uses regularly to aid in the process of administration. Configure your swap space (including adding space in an emergency) to get the most out of your system. In this article, you'll learn how to monitor your system to determine an effective swap space figure as well as examine methods for using swap space for more than just secondary random access memory (RAM).
• Mathematics on a UNIX workstation — Mathematics is the King of Science. Commercial uses for mathematical workstations are vast: From basic engineering to designer drugs and from gene therapy to celestial navigation, mathematics rules the world. Many tools are available for use on UNIX that can satisfy your quest for mathematical enlightenment. This article shows you the way to mathematical nirvana on a UNIX workstation.
• Hatch Python Eggs with Setuptools — Setuptools framework, a side project of PEAK, provides easier package management and distribution than distutils. Setuptools lets you package your libraries in a single-file archive called an “egg,” similar to Java JAR file, but for Python. Like the Perl CPAN and Ruby Gems tools, the ez_setup tool bootstraps the rest of setuptools. The ez_install tool that comes with it does the same thing in conjunction with “Cheeseshop” (PyPI).
• Build a 2006 Space Odyssey HAL 9000 with Autonomic Computing — In this article see how HAL 9000, the computer in the 2001: A Space Odyssey movie could predict equipment failure, answer personal questions, learn to sing “Bicycle built for Two,” and go insane, based on IBM Build to Manage Toolkit components. Also, see how autonomic computing can be implemented today; determine if there is such a thing as a Hofstadter-Moebius loop in programming; and discover the meaning of HAL.
• Data Visualization Tools for Linux — Applications for graphical visualization of data on Linux are varied. Explore a variety of open source data visualization tools such as gnuplot, GNU Octave, Scilab, MayaVi, and Maxima to better decide which is best for your application. Each has its advantages and disadvantages and targets different applications.
• IBM Releases Free Application Server for Linux — New WebSphere Application Server Community Edition Version 1.1 is now available for download. Version 1.1 preintegrates Tomcat and offers support for Ajax, PHP, and JSE 1.5 to accelerate your application development.
