IBM has published the following new technical articles, tutorials, and downloads on its DeveloperWorks and AlphaWorks websites. 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.

• The nuts and bolts of PowerPC assembly language — The POWER5 processor is a 64-bit workhorse used in a variety of settings. Starting with this introduction to assembly language concepts and the PowerPC instruction set, this series of articles introduces assembly language in general and specifically for the POWER5.
  • Part 1: Programming concepts and beginning PowerPC instructions
  • Part 2: The art of loading and storing on PowerPC
  • Part 3: Programming with the PowerPC branch processor
  • Part 4: Function calls and the PowerPC 64-bit ABI

• Python Elegance and Warts — Python has greatly increased its number of syntactic features and built-in functions and types, making it no longer a language that experienced programmers can pick up “in an afternoon.” This article discusses the new features that have been added to Python, and weighs in on which ones are truly valuable and which just add unnecessary complication.
• Eclipse: Empowering the universal platform — This technical briefing will take a deep dive into some of the most important, feature rich projects that the Eclipse community is developing.
• State of the VNC art — Are you adept with Virtual Network Computing (VNC)? If not, you'll find that learning even a little about this desktop sharing system pays off big in your daily development or system administration responsibilities.
• Open Standards software and Next-Gen NASA telescope — A senior software engineer and a marketing manager, both from IBM Rational, talk about open standards system development with the James Webb Telescope project.
• Open Community Tools: An open stack development platform — Explore the innovation of open source solutions available from IBM and see the power and flexibility of an open community development environment.
• Virtualization with coLinux — Virtualization with VmWare, Xen, and Kernel-based Virtual Machine (KVM) are all the rage these days. But did you know that you can run Linux cooperatively with Microsoft Windows? This article explores Cooperative Linux (coLinux), starting with a quick introduction to virtualization and then looking at the approach taken by coLinux.
• Shaping the future of secure Ajax mashups — Current Web browsers weren't designed to easily and securely get content from multiple sources into one page. Discover how developers have stretched the available tools to fit the task and how doing so has put strain on the resulting applications with respect to security and scalability. Also, learn about several browser improvements being proposed to remedy the situation and how to become part of the conversation.
• AES encryptions with Kerberos 5 — You can use Kerberos to verify the identities of users and principals over networks.
• Test GUI-less Web services with Rational Tester — IBM Rational Tester for SOA Quality is a functional and regression testing tool that enables the creation, comprehension, modification and execution of testing GUI-less Web services.
• Automated user acceptance testing made easy — Selenium is a Web testing framework that establishes a new approach to validating Web applications by testing as if it were the browser itself. Selenium is easy to use for both developers and non-developers.
