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.

• Virtual Linux — This article explores the ideas behind virtualization and then discusses some of the many ways to implement virtualization. We also look at some of the other virtualization technologies out there, such as operating system virtualization on Linux.
• Delve into UNIX process creation — System administrators must know how processes are created and destroyed within the UNIX environment in order to understand how the system fits together and how to manage misbehaving processes. Examine the life cycle of a process so that you can relate what you see happening on your system to what's going on within the kernel.
• Get the most out of Z shell — Examine key parts of the Z shell (zsh) and how to use its features to ease your UNIX system administration tasks. Z shell is a popular alternative to the original Bourne and Korn shells. It provides an impressive range of additional functionality, including improvements for completing different commands, files, and paths automatically, and for binding keys to functions and operations.
• Speaking Unix, Part 6: Automate, automate, automate! — Discover how to use shell scripts to mechanize virtually any UNIX personal or system task, and learn more command-line tricks while doing so. Scripts can monitor, archive, update, report, upload, and download. Indeed, no job is too small or too great for a script.
• Building a CDT-base editor, Part 5: Using PDOM — This article, fifth in a five part “Building a CDT-based editor” series, shows how the C/C++ Development Tooling (CDT) performs code completion. Learn to understand how the CDT performs code completion. This is one of the CDT's most useful capabilities because it reduces the amount of code the user needs to type and remember.
• The Abdera project for high-performance Atom feeds — This article demonstrate how you can start to implement Atom-enabled applications using a new open-source project, called Abdera, currently under incubation at the Apache Software Foundation. Its a good article showing you some tricks with its Feed Object Model, XPath and XSLT support, extension handling and incremental parsing model.
• Real-world Apache Derby: Who needs Ajax, anyway? — Asynchronous JavaScript + XML (Ajax) is a dynamite technique for greatly enhancing the user experience on the Web. Discover how to structure a simple, database-centric solution that provides a mechanism for collecting responses to questions about SOX compliance.
