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 . . . !

• Balancing Power, Cooling, and Performance — Power consumption, supply voltage, junction temperature, system cooling requirements, and processor clock rate are all physically and thermodynamically related. By understanding the relationships, system cost and complexity trade-offs, and resource requirements, system designers can strike a better balance between requirements. See how you can incorporate emergent cooling and adaptive power control methods into embedded system designs.
• PowerPC Development from the Bargain Basement — The Kuro Box promises something fairly interesting: a usable single-board PowerPC computer, for only US$160 — when other PowerPC development boards often cost ten times as much. Peter Seebach guides you through setup and install in this hardware howto.
• Create a Kuro-based Web album — The odyssey to build a robot submarine continues: in this installment, just a little bit of code is enough to get a photo album running on our Kuro-based embedded system. Find out more about the hows (and whys) of small, clean, embedded development — using only Free Software.
• Bridging XPCom/Bonobo — Discover the concepts and techniques required for bridging two component architectures, so that the components from one architecture can be used in another environment. These quick tutorials walk you through the techniques and implementation steps.
• Geronimo! Part 1: The J2EE 1.4 engine that could — Java-based open source development has come a long way since the early days of developers sharing GUI libraries. Geronimo is a large-scale project attempting to create a certified J2EE 1.4 server based on existing open source components. Take a tour through the Geronimo maze with Sing Li as your guide. Also, Gluecode Software CTO and principal Geronimo contributor Jeremy Boynes shares his perspective on Geronimo and go here to learn how to use the new Eclipse plug-in for Apache Geronimo.
• New release of Gluecode SE 1.1 for Linux — Gluecode Standard Edition (SE) is a Java-certified, production-grade platform designed to allow developers to rapidly deploy and manage their applications. Built on Apache-based technologies, Gluecode SE relies on the Apache Geronimo application server as an integration point for mature, proven open source. Download Gluecode SE 1.1-Beta
• How LDAP works best with J2EE and EJBs — Here's a real good series of articles recently published, that explores LDAP (Lightweight Directory Access Protocol) Enterprise Application Programming. Part 1 provides a guide to learning the basics of Java LDAP programming and gives you a working knowledge of LDAP. Part 2 shows you how to setup LDAP for an Application Server. Part 3 provides details on how to use LDAP authentication in your J2EE Application Server application. Part 4 teaches you EJB Programming with LDAP and roles for security and their underlying LDAP groups. In Part 5 learn EJB Programming using Methods, Instance Level Security and LDAP.
• WSDL Eclipse Modeling Framework client code for Linux — This tutorial shows you how to use the WSDL1.1 Eclipse Modeling Framework plug-ins that are packaged with Rational Software Architect. Upon completion of this tutorial, you will understand Eclipse Modeling Framework models, have a good understanding of the WSDL1.1 e-core model, be able to create a new underlying WSDL data-file from Eclipse Modeling Framework client code, Load from, parse, and save to a WSDL data-file, and Discover and modify WSDL elements, attributes, and type information. Download the Rational Software Architect Linux Full or Linux Light version trail code at no charge.
• IBM's 320,000 Bloggers coming soon — IBM is planning to introduce what could be the largest corporate blogging initiative so far, in a bid to encourage its 320,000 staff to become more active in online tech communities. The world's largest computer company has prepared a broad range of programs and online materials that staff can access to find out how they can start to blog. Behind the scenes, a small handful of technical innovators developed and deployed an internal blogging service that has grown in a period of just 18 months to just shy of 9,000 registered users spanning 65 countries, 3,097 individual blogs, 1,358 of which are considered active, with a total of 26,203 entries and comments — all of which has been put together strictly through word-of-mouth promotion. And it's still just a pilot.
