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 . . . !

• Linux 2.6 kernel: Making Your First Hack — In this second of a two-part series, discover the organization of the Linux kernel source, build an understanding of system calls, and craft your own kernel modules and patches.
• LPI exam 101 prep: Hardware and Architecture — In this first in a series of five tutorials, Ian introduces you to configuring your system hardware with Linux. By the end of this tutorial, you will know how Linux four packages — Auditor, Whoppix, Knoppix-STD, and PHLAK — that bring you that ability through the magic of LiveCD.
• JUnit nail-guns antipatterns — The advent of JUnit has been a boon to developers. Unfortunately, many think it's enough to learn the JUnit API and write a few tests in order to have a well-tested application. This idea is worse than not testing at all because it leads to a false sense of code health. Learning JUnit is the easiest part of testing. Writing good tests is the hard part. This article presents some common JUnit antipatterns and shows how to resolve them.
• Roll your own app server with Apache GBeans — Geronimo provides integration with third-party components through its unique GBeans feature. Apache Geronimo team member and committer, Jeff Genender, demonstrates this feature by showing you how to build and configure a third-party open source project with a GBean that integrates the OpenSymphony Quartz scheduler into Geronimo.
• Build a digital animation system — Growth in the Digital Special Effects (SFX) and computer animation industry, a sub-segment of the media and entertainment industry, is exploding world wide. A number of reasons have caused this growth and they involve the merging of technology and imagination.This article illustrates the dynamics and business model and processes of the animation effects industry and introduce the existing infrastructure.
• An overview of the Atom 1.0 Syndication Format — Web content syndication is an area of growing importance on the Internet. Atom 1.0 provides a simple, well-defined, and unambiguous format for content syndication on the Web. This article shows you how this popular Web content syndication format stacks up to RSS, discusses Atom's technical strengths relative to other syndication formats, and offers several compelling use case examples that illustrate those strengths.
