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.

• Eyes Inside the Silicon — Hybrid SoCs employing PA technology-based software interfacing to highly customized hardware state machines can help designers unlock the power of application-specific hardware acceleration. Continuing the SoC drawer series, this article provides an overview of on-chip debug hardware and software tools to make SoC design, implementation, and test easier.
• GNU Project Debugger: More fun with GDB — Learn about the GNU Project Debugger (GDB) macro capability that allows you to personalize and customize GDB to have just the tools you need. The previous article, “Fun with strace and GDB,” covered the basics of using these tools to explore your system and attach to programs that are already running to see what they were doing.
• Version Control for Linux — Version control systems or source configuration systems (SCM) is one of the most important tools you probably didn't learn in school, mainly because without one an accident is inevitable. In this article get an overview of SCM, including its benefits and architecture, CVS, Subversion, Arch, Git, and a compare and contrast of new approaches to earlier methods.
• Remove the smell from your build scripts — Smelly code will surely cost you valuable time. How much time do you spend maintaining project build scripts? Probably much more than you'd expect or would like to admit. This article shows you how to improve a number of common build practices to create consistent, repeatable, and maintainable builds. Knock the stink off those scripts.
• UNIX tips: Become a better blogger with UNIX — Did you know that blogging and UNIX go hand in hand? The native Web and text-processing tools of UNIX enable you to create your blogs quickly and easily. Discover command-line tools and some handy tips for improving your UNIX blogging skills.
• The ultimate Mashup with RDR and OWL — This tutorial gives you a good background in both RDF and RDFs so you'll be ready to build ontologies for your Machup Web services, and also able to make use of RDF's power with other projects as well. This tutorial will show you how to represent information in RDF, which will allow you to create an ontology for your Mashup, using the XML-based Web Ontology Language (OWL).
• SimpleXML processing with PHP — The SimpleXML extension, which is bundled with PHP version 5, enables PHP pages to query, search, modify, and republish XML in a PHP-friendly syntax. It's a useful addition to the PHP programmer's toolkit and can be a reliable and robust means of processing XML from within PHP.
