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. Some require free registration. Enjoy . . .

• Wireless devices consume web services — JSR 172 specification provides support for remote service invocation and XML parsing at the device level — this means that developers don't have to embed such functionality into each wireless application. This article introduces the remote service invocation optional package API that allows web services to go wireless.
• Spin up a Linux LiveCD — Many Linux distributions have been designed as so-called “LiveCDs,” CDs that can be booted directly into working Linux systems. In contrast to “rescue mode” bootable options available with most widely used distributions, these LiveCDs are designed to provide a full set of working tools when booted from CD. Some are general-purpose, some highly specialized. This article takes a look at this fast-growing segment of the Linux market.
• Secure programming with the OpenSSL API — Learning how to use the API for OpenSSL — the best-known open library for secure communication — can be intimidating, because the documentation is incomplete. Fill in the gaps, and tame the API, with the tips in this article. After setting up a basic connection, see how to use OpenSSL's BIO library to set up both a secured and unsecured connection. And learn a bit about error detection as well.
• Yellow Dog Linux on Power Mac G5 — The IBM PowerPC 970 CPUs are well-designed, high-performance chips that ship in millions of end-user systems under Apple Computers' Power Macintosh G5 moniker. These CPUs greatly lower the bar for 64-bit computing on the desktop and on small servers. Currently, Terra Soft's beta Y-HPC is one of only two 64-bit Linuxes that run on G5s. As their names imply, the G5-enabled betas — both 32- and 64-bit versions — are for evaluation only. This article is an early look at the promise of Linux on a G5 and is intended for developers interested in trying out this combination in anticipation of production-ready releases to come.
• Whats the big deal about Cloudscape anyway — IBM Cloudscape is an open standards small footprint database that tightly embeds into Java applications. Cloudscape aims to be easy to use for software developers and requires zero administration for end users. Here are new articles designed to fill-in all the gaps and answer the question: Whats the big deal about Cloudscape anyway?
  – Cloudscape 10: A Technical Overview
  – Cloudscape frequently asked questions
  – Integrating Cloudscape and Tomcat
  – IBM Cloudscape: Understanding Java class path
• Securing Linux: What it means to be secure — Only the paranoid survive, and that is no less true when securing Linux systems as any other. Fortunately, a host of security features are built into the kernel, are packaged with one of the many Linux distributions, or are available separately as open source applications. The first in a series, this article starts you on your way to understanding security concepts and potential threats, and sets the stage for what you really need to know: how to secure and harden a Linux-based installation.
• LPI certification 101: Basic administration — In this second of a series of four tutorials on the 101 exam, you will learn how to use regular expressions to search files for text patterns, how to locate files on your system, and how to take full control of Linux processes. You'll even get a whirlwind introduction to shell pipelines, redirection, and text processing commands. By the end of this tutorial, you'll have a solid grounding in basic Linux administration and will be ready to begin learning more advanced Linux system administration skills in the follow-on tutorial.
• LPI certification 101: Intermediate administration — This tutorial (Part 3) is ideal for those who want to improve their knowledge of fundamental Linux administration skills. We'll cover a variety of topics, including system and Internet documentation, the Linux permissions model, user account management, and login environment tuning.
• Using Linux To Burn CDs? — Linux offers powerful, flexible tools for creating CDs. You can create disks that are readable on almost any platform and create .iso files for download and distribution.
• Connect KDE apps using D-BUS — D-BUS is an up-and-coming message bus and activation system that is set to achieve deep penetration in the Linux desktop. Learn why it was created, what it can be used for, and where it is going.
• Well-structured, modular code in the Java language is possible — If you work on large-scale development projects, then you're familiar with the advantages of writing modular code. Well-structured, modular code is easier to write, debug, understand, and reuse. The problem for Java developers is that the functional programming paradigm has long been implemented only via specialized languages such as Haskell, Scheme, Erlang, and Lisp. This article, shows you how to use functional programming constructs such as closures and higher order functions to write well-structured, modular code in the Java language.
• IBM releases Eclipse Development Package for Linux — The IBM Development Package for Eclipse enables you to build and run Java applications with this Eclipse-based development tool on the Linux platform, which includes the latest IBM Java runtime for Linux. No registration is required.
• Build an Eclipse Rich Client Platform app on Linux — This two-part tutorial series introduces Eclipse and its Rich Client Platform (RCP) and shows you how to assemble an RCP application to create an elegant client-side interface for your own business applications. Part 1 walks you through the steps to implement an RCP application, including creating a project within the Eclipse 3.0 IDE, defining a plug-in manifest, and creating a basic perspective. Using these components, you can create additional supporting Java classes and launch a stand-alone RCP application.
