Six technical articles on Linux from IBM
Jun. 06, 2003

IBM has published the following six Linux-related articles and tutorials on its developerWorks website. They cover a range of interesting (though not embedded) technical topics. Some require free registration. Enjoy . . .
  • Build a cross-platform test network with Samba and GRUB -- This tutorial shows how to combine Samba and GRUB to build a compact, highly adaptable, cross-platform test network, capable of booting and networking a large number of operating systems on a small number of machines. Though Samba and GRUB can manage many different operating systems, this tutorial focuses on Linux and Windows.

  • Grid computing Video -- Are you still wondering what Grid computing is all about? IBM assures you that this Grid computing video will help you. Learn more about the Butterfly Gaming Grid and other real-life Grids. This should clue you in to what Grid computing is all about.

  • Linux clustering with MOSIX -- This tutorial explains what it is, how you go about cluster-enabling your Linux system, and how you can benefit from setting up a cluster. By the end of this tutorial, you will have set up your own MOSIX cluster. MOSIX is a special transparent form of clustering that is very easy to set up and can produce positive results with only a minimal investment of time and energy.

  • Administer Linux on the fly -- The /proc filesystem is one of Linux's great features, and this article gives you a thorough grounding in some of its most useful aspects. With it, you can administer many details of the operating system without ever having to shut down and reboot the machine, which is a boon for those who need to keep their systems as available as possible.

  • Create a four-tier Web services application on Linux -- Web services enable you to quickly integrate applications across multiple platforms, systems and even across businesses. This tutorial demonstrates how easily you can make your DB2 data accessible through Web services on Linux. In the tutorial, you'll create a sample four-tier application that retrieves information stored in a DB2 UDB V8 database.

  • Create Hello World Portlet on Linux with new IBM Jetspeed tutorials -- IBM has released two tutorials on Jetspeed advanced portlet technology. Part 1 takes you through portlet development by engaging Jetspeed an open source project from the Apache Software Foundation, which enables portability across all platforms. Jetspeed supports JSP as the building block for portlets. It also provides Jetspeed-specific predefined taglib blocks that make repetitive tasks easier to perform. In a addition to those features, Jetspeed provides developers with an advanced caching mechanism and support for WML. The tutorials teach you how to use this open-source architecture to implement wireless and Web-based portlets. With the knowledge you gained by creating the Hello World Portlet in Part 1, you will learn in Part 2 how to stream into the portlet you've created using Apache Tomcat.
