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 . . . !

• ClearQuest Client for Eclipse — Rational ClearQuest client for Eclipse provides most of the ClearQuest functionality inside the Eclipse environment. It also provides a seemless integration with many of the Eclipse views and editors. This article provides you with a good understanding of the ClearQuest Client for Eclipse and it will show you how to perform change management as part of your Eclipse workflow, rather than making it a “task” of its own.
• Zap Java bugs before they bite with PMD — Even with just its built-in rules (which are quite extensive), PMD will almost certainly find some real problems in your code. Some of them will be minor, but some won't be. PMD, an open source static analysis tool, can be a worthwhile addition to your bug-zapping arsenal. Elliotte Rusty Harold explains how to use PMD's built-in rules and your own custom rule sets to improve the quality of your Java code.
• Roaming charges: Blown by the winds of change — First up in the new year, Larry parses what the mergers and movements in wireless players mean to the consumer. "Sometimes, the winds of change hit you in the face without warning…There was a decal by the store entrance that touted their new in-store wireless service provided by the local phone company."
• Big iron lessons: FPU architecture, now and then — Floating point provides a convenient, approximate representation of real numbers that can greatly simplify scientific and engineering algorithms. This article gives an overview of two floating point formats used in the z990 architecture and discusses key FPU issues that system architects should consider in new designs.
• Heterogeneous Cluster with coLinux and openMosix — You can create a cluster using any of three basic approaches: full migration to a single platform, partial migration, or a mixed or hybrid creation. In this article, learn how cluster agents fulfill the latter approach, and see how coLinux and openMosix can combine to offer a high-performance cluster middleware in a heterogeneous environment. In this heterogeneous environment, Linux provides the stability and performance, and Windows users continue to use their apps and never notice the difference.
• High-Performance and High-Availability Clustering — This paper introduces basic clustering components and software tools that can be used to build a Linux cluster on IBM eServer OpenPower 710 by utilizing its 64-bit POWER5 architecture. This paper is intended as an introduction for someone interested in building a new Linux cluster running on OpenPower 710 servers or converting an existing cluster to OpenPower 710 servers.
• IBM releases Rational Application Developer v6.0 for Linux — The IBM Rational Application Developer for Linux trial download enables developers with diverse technical backgrounds, and even those unfamiliar with Java, to quickly build rich, data-driven applications. Features, benifits and support includes: Eclipse 3.0 Integration, UML Visual Editor, Tomcat Jakarta, Ant scripting, EJB universal test client, Integration with Rational ClearCase, Struts support, JSP and servlet wizards, JSF Component Layout, Swing GUI Construction, SWT GUI Construction, Visual portlet development, Portlet templates, SQLJ support, SQL query builder, Support for DB2, Informix, IBM Cloudscape, Microsoft SQL Server, Oracle9i and Sybase and Web services and SOA development tools.
• Briefing on Linux solution to replace Microsoft Office — A new worldwide Tech Briefing on Migrating and Developing New Applications for Linux will be held in March, go here to find out where its being held near you. The free Tech Briefing will cover a Linux collaboration solution to replace microsoft office, tools to migrate Infrastructure workloads, tools to migrate windows applications, tools to develop new applications on linux and tools to support linux based team development.
