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.

• Don't be a Victim of the Pox on Modern Engineering — Between IP litigation and ever greater demands for “baseline” functionality that requires licensing, developing new products has become a treacherous minefield. In this article, Lewin Edwards outlines the dangers making it harder for engineers to get out there and build something.
• Port Your Code Around the World with m17n — To make Linux applications usable worldwide — with no inequity between Western dialects and languages around the world — you must be able to input, store, retrieve, and render any language, no matter how complex. The multilingualization library, or m17n, provides a single solution for all languages on UNIX-like platforms.
• Hardware and Software Fusion for Low Cost & Movies — Explore technical issues in video playback, and see how a blend of hardware and software achieves good performance at a reasonable cost. Learn how to show movies on a scriptable, network connected appliance. Also, Lewin Edwards reveals that MP3 does not mean MPEG-3, which alone is worth the price of admission.
• CDT C/C++ parsing and its abstract syntax trees — Parsing is one of the CDT's most crucial functions, but because of its complexity, parsing is also one of its least-understood aspects. This article introduces the parsing process used by the Eclipse C/C++ Development Tooling (CDT). This will help you Get a handle on one of the C/C++ Development Tooling's most crucial functions: the parsing process — for error detection, indexing, and code-completion.
• WHATWG is doing with HTML5, Web Forms, and XHTML — This is a very good 2 part series about the WHATWG. The Web Hypertext Application Technology Working Group (WHATWG), is a loose collaboration of browser vendors (Mozilla, Opera, and others), who focus their improvements towards creating Web applications. Part 1 focuses on two specifications being developed by WHATWG: Web Applications 1.0 (HTML5) and Web Forms 2.0. Part 2 covers the radical cleanup of XHTML, the W3C's new Rich Client Activity, and the work in process at the W3C to specify the future of Web markup.
• Crossing Borders: What's the secret sauce in Ruby on Rails? — Ruby on Rails seems to be a lightning rod for controversy. At the heart of most of the controversy lies amazing productivity claims. Rails proponents boast of incredible productivity, with some claims of 10 to 1 over Java development. This article explores the compromises and design decisions that went into making Rails so productive within its niche and how Ruby on Rails, like a nail gun, saves so much time.
• Cache in with JSON to Ajaxianize your web apps — JSON helps provide an Ajaxian nature to a Web application. Learn an elegant way to cache metadata on the client side with the help of server code, which provides JSON-formatted (JavaScript Object Notation) stringified metadata. This approach also enables you to handle multivalue and multigroup attributes in a manner similar to Ajax.
• Build Ajax fuctions without Javascript coding — Get familiar with the Sun Ajax4jsf open source framework, which adds Asynchronous JavaScript + XML (Ajax) capabilities to JSF applications without having to write any JavaScript code. This tutorial will show you how to build an Apache Geronimo applications using JavaServer Faces and Ajax functionality with Ajax4jsf.
• Rich Ajax Slide Shows with DHTML and XML — Learn to create an Asynchronous JavaScript and XML (Ajax) client-side slide show that's animated using “Ken Burns Effects.” Here, you discover how to build XML data sources for Ajax, request XML data from the client, and then dynamically create and animate HTML elements with that XML.
• Tunneling with SSH: Windows to UNIX connectivity in a secure world — This article describes the setup of a simple SSH client connecting to an AIX- or Linux-based SSH server that allows a typical, technically literate individual the ability to set up, configure, and operate a flexible means of tunneling data and services over the SSH service. Use OpenSource tools, such as Secure Shell (SSH), PuTTY, and Cygwin, to create secure connections to almost any resource you need to access.
• Setting and managing permissions on UNIX — UNIX provides robust tools and infrastructure so that you can both protect and share information. This article looks at user privileges and, in particular, examines how to manipulate file permissions to restrict or share your directories and files with others. Understanding permissions is crucial if you want to speak UNIX fluently. Learn how to manipulate file permissions to protect your files, or share them with others.
