| 10 from IBM -- PPC x-compiling, JXTA, BIND, XAMPP, RELAX NG . . . |
Dec. 03, 2004
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 . . .
- Build a GNU cross compiler for PowerPC -- Learn how to build a GNU cross compiler for PowerPC code development by downloading the PowerPC 750GX/FX evaluation kit. The source code illustrates how to initialize and utilize various features of the processor--memory management unit, interrupts, and debugging features. The board schematics provide an example of how to connect the processor to a system controller (bridge) chip and other components in the system.
- Using JXTA for Wireless Messaging -- Learn how to use JXTA technology to integrate thin Java 2 Platform, Micro Edition (J2ME) clients into enterprise-scale messaging applications by developing a set of classes that let you integrate J2ME clients into JMS (Java Message Service) applications running on Java 2 Platform, Enterprise Edition (J2EE) servers.
- What is your system Name and Address right now? -- IBM has written a time saving BASH script that can change the system name and network address of Linux systems. This configurator was created for IBM administrators and other internal use, but has now been released for download.
- Secure Web services with the GSI API -- Get an introduction to security concepts -- credentials, proxy, authentication, and delegation. Then learn how to add basic message-level security to Web services and clients using the Globus Security Infrastructure API.
- Build a DNS server with ISC BIND -- This tutorial from dW shows you how to leverage Linux to get the most from your network. Specifically, it describes how to set up DNS with Internet Systems Consortium (ISC) BIND. Sample code and configuration files are provided throughout to aid understanding.
- Install XAMPP for easy, integrated development -- Open source stacks such as XAMPP from Apache Friends are simplifying open source development by making it easier to write and distribute applications in a stable and standardized environment. Traditionally, AMPP -- Apache, MySQL, PHP, and Perl -- have all been installed and configured as separate products. The trend of combining them into integrated middleware stacks promises to make open source development more competitive with J2EE application development, at least for low-end applications.
- RELAX NG with custom datatype libraries -- RELAX NG can do almost everything the W3C XML Schema language can do, including verifying constraints on text content and attribute values specified with the W3C XML Schema simple types. However, some constraints still can't be stated in anything less than a Turing-complete language, and RELAX NG is not such a language. Fortunately, you can extend RELAX NG dynamically with custom validation code — written in the Java.
- PowerPC atomic instruction prevents code meltdown -- Something as simple as incrementing an integer can fail in a concurrent environment. This article illustrates the failure scenario and introduces the PowerPC's coping mechanism: atomic instructions. Learn how to close the Window of Death with these assembly-level instructions to update memory correctly, even in the face of concurrency.
- High-performance SQL for Linux -- Its a SQL tour through the DB2 TPC-C benchmark implementation. This article introduces advanced SQL features which are being used in IBM DB2 Universal Database for Linux, UNIX TPC-C benchmarks. Find out how to use efficient SQL query plans, which in turn will mean that the only codepath that is necessary will be executed.
- Analytics Acceleration Grid Environment, Part 3 -- In part three of this three-part series, the authors offer a real-world implementation example of how the Analytics Acceleration Grid Environment (AAGE) can be used to deliver a virtual system environment that supports a wide range of application requirements, and makes the best, most efficient use of computing resources and data regardless of where or in what format they reside.
