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 . . . !

• What's New in Cell Phone Technology — Larry finds inspiration in new horizons this month, as his two-year-swap contract affords him an up-close look at what's new in cell phone technology. “This year's model of swappable-outtable phone has more technology crammed into it than ever before. Moreover, it has more usable features (ones I want) packed into that crammed technology. As a consumer, I like what I'm seeing.”
• Five Pitfalls of Linux Sockets Programming — The Sockets API is the de facto standard API for networking applications development. Although the API is simple, new developers can experience some common problems. This article identifies the most common of these pitfalls and shows you how to overcome them.
• The ATX Case and Power Supply — The recent blade.org announcement heralds that IBM and Intel are looking to standardize blade hardware designs, allowing blade systems from multiple vendors to work together. It's no surprise that Intel is interested in this — its own ATX standard has been a massive success. This article looks at the history of ATX and some of the lessons learned about power supply and chassis standardization.
• An early look at JUnit 4 — JUnit is almost indisputably the single most important third-party Java library ever developed. It promises to simplify testing by exploiting Java 5's annotation feature to identify tests rather than relying on subclassing, reflection, and naming conventions. In this article, obsessive code tester Elliotte Harold takes JUnit 4 out for a spin and details how to use the new framework in your own work.
• Man's Best Friend (outside of a dog) — “Outside of a dog, a book is man's best friend. Inside of a dog it's too dark to read.” — Groucho Marx. When is the electronic book going to be as useable as the old-fashioned kind? How do technologies need to change to bring e-books out of the geeky, early adopter ghetto and into digital bookstalls everywhere?
• Weigh your options before building a customizable UI — Customization typically offers users the ability to manipulate shiny objects, but not much real power. Wouldn't it be better to put the time into supporting a more powerful and flexible user interface?
• Enhanced XML features in Firefox 1.5 — The open source Firefox Web browser continues to grow in popularity. Discover new XML features for the fastest-growing Web browser, including XML parsing, XHTML, CSS, XSLT, SVG, and XForms. Additional third-party extensions provide even more XML support.
• Ajax paves the way for better Web applications — This article gives you a good understanding of the fundamental principles of Ajax and a nuts-and-bolts knowledge of the client and server side components that participate in an Ajax interaction. These are the building blocks of a Java-based Ajax Web application. In addition, you will be shown some of the high-level design issues that come with the Ajax approach.
• Object Code for the PowerPC 405 and 440 Core Models — As of September 20, 2005, you can news in this edition of the Power Architecture community calendar!
