10 from IBM -- Linux for newbies, testing, validation, reliability...
Mar. 11, 2005

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 . . . !


  • Basic Tasks for New Linux Developers -- Linux systems require you to log in, become the super user (or root) for some tasks, open a terminal or shell window, and mount a CD-ROM. If you are new to Linux, this article will guide you through these tasks and more.

  • Test-suite flaws are no joke with Jester -- Test-first programming is the least controversial and most widely adopted part of Extreme Programming (XP). By now the majority of professional Java programmers have probably caught the testing bug. Jester is an important addition to the agile programmer's toolbox. It finds gaps in code coverage no other tool can, which translates directly into finding and fixing bugs. This article introduces Jester and shows how to use it for best results.

  • Automate Java code validation and reduce Code Review cost -- This article introduces a new feature of the Rational Application Developer (IRAD) and Rational Software Architect (RSA) products, one that allows you to automatically validate Java code against a pre-defined set of rules and best practices. Code Review is designed to help you detect many well-known causes of problems in Java and Java 2 Platform, Enterprise Edition (J2EE Platform) applications. Free Rational Application Developer download for Linux can be found here as well as the download for other platforms.

  • Reliability and availability: What's the difference? -- How do you design a computing system to provide continuous service and to ensure that any failures interrupting service do not result in customer safety issues or loss of customers due to dissatisfaction? Historically, system architects have taken two approaches to answer this question: building highly reliable, fail-safe systems with low probability of failure, or building mostly reliable systems with quick automated recovery.

  • Automate Perl module deployment -- If you run Perl across many different computers of any sort, you know how frustrating it can be to install Perl extension modules across those machines. The administrative process is even worse if you have a Web server farm and need to keep each machine up to date with a set suite of extension modules for your installation. CPAN helps, but there are issues with CPAN that make it an unwieldy solution for use on a network.

  • What could a psychologist do for my engineering team? -- If your work includes speech technology, you know that speech user interfaces and human factors professionals seem to get a lot of attention. But how do they work together, and just as importantly, why?

  • Chips in SPACE! -- In this article, developers blast their most unusual schemes for chip use in space, once again proving that a little science fiction on television can be a dangerous thing.

  • Introducing the PowerPC SIMD unit -- AltiVec? Velocity Engine? VMX? If you've only been casually following PowerPC development, you might be confused by the various guises of this vector processing SIMD technology. This article covers the basics on what AltiVec is, what it does -- and how it stacks up against its competition.

  • PowerPC Architecture Book, Version 2.02 -- This 3 volume set, Version 2.02, defines the instruction and registers used by application programs, the storage models, privileged facilities, and related instructions for the POWER5 processor family.

  • How is software development like moviemaking? -- To introduce beginners to the RUP framework, the process of software development is often compared to the construction process. But software development with the RUP is actually more like making a movie than building a house, as this article suggests.
