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.

• Real-time garbage collection with Real-time Java — Metronome GC, part of IBM WebSphere Real Time, deterministic GC behavior that, when combined with other features, enables developers to write hard RT applications in the Java language
• Real-time Java: Threading and synchronization — This article examines aspects of threading and synchronization that an implementation of the Real-time Specification for Java (RTSJ) must support.
• Memory leak patterns in JavaScript — Plugging memory leaks in JavaScript is easy enough when you know what causes them. This article walks you through the basics of circular references in JavaScript and explain why they can cause problems in certain browsers, especially when combined with closures. After seeing some of the common memory leak patterns you should watch out for, you'll learn a variety of easy ways to work around them.
• Integrate JavaScript libraries to enhance Google Web Toolkit widgets — Take a legacy path to advanced GWT controls. Find out how to give GWT controls advanced functionality with relatively simple coding by integrating a popular JavaScript grid component with a GWT application.
• Java without the Java know-how — Learn how to build a simple dynamic Java Web application without knowing the Java language using Rational Business Developer Extension and Enterprise Generation Language (EGL).
• UNIX Command Line in One Sentence — Speaking UNIX is simply a matter of building a sentence. An executable is a verb, output is a noun, and the shell operator is a conjunction. Virtually all non-trivial problems require you to filter good data from bad. Discover the many UNIX command line utilities that use regular expressions to discern the relevant from the irrelevant.
• XL Fortran Compiler for Cell BE on Linux — Develop complex, computationally-intensive programs with IBM XL Fortran Alpha Edition for Cell BE Processor on Linux. These high-performance XL compilers are derived from a common code base, helping support consistent compiler performance and ease of program portability across multiple OS and hardware platforms.
• Advanced Emacs text operations — You get a hands-on demonstration of advanced editing techniques, including how to perform a recursive edit, mark and use rectangles of text, and handle complex selection techniques using the kill ring and the secondary selection.
