Linux can serve as a client desktop or server right out of the box, a flexibility that slows its booting process. This article shows you options to increase the speed with which Linux boots, including two options for parallelizing the initialization process. It also shows you how to visualize graphically the performance of the boot process.

UML users and Web developers can now create robust event models and multimodal applications with IBM Modeling and Integration Tools for State Chart XML. Plug-ins for Rational Software Architect, and Mozilla for Web 2.0 mashups, transform UML 2.0 state charts into SCXML documents for export.

This tutorial takes you through the process of setting up the Perl Database Interface (DBI) to work with the IBM Informix Dynamic Server (IDS). See examples of how to exercise a variety of DBI features and learn how to configure CPAN module installation, driver installation, script automation, data structures, pitfalls, and Perl interaction with IDS.

This article discusses the PowerPC ABI for 64-bit ELF (UNIX-like) systems and how to write and call functions using it. This is helpful for writing 64-bit programs for the POWER5 and other PowerPC-based processors more effectively, whether you program in assembly language or not.

Take a step-by-step guide to creating custom Live CD’s on Fedora Linux. Fedora Linux is a popular and mature Linux distribution, which released its first official Live CD in December 2006. Learn how to build your own custom and easy-to-use Live CDs using a rewrite of Pilgrim, the Fedora Live CD creation tool.

Simplify the task of including business graphics in rich-client applications with Standard Widget Graphics (SWG), a set of standard graphic objects built into the SWT from Eclipse. SWG provides new widget controls and an animation framework that share a common programming model with the existing controls in SWT.

Get easier management of blank form templates and central storage of completed form instances with IBM Content Manager Integrator. This tool enables integration of open XML-based eForms components between Workplace Forms and DB2 Content Manager.

This first article of a three-part series introduces PHP5's XML implementation and help those relatively new to using XML with PHP to read, parse, and manipulate, and write a short and uncomplicated XML file using the DOM and SimpleXML in a PHP environment.

This plug-in adds new project types to the Eclipse C/C++ Development Tooling (CDT), providing a convenient way of setting PowerPC-specific switches to the GNU C and C++ compilers, linker, and assembler.

Scalable Vector Graphics (SVG) provides an easy way to declaratively create an image using XML, and XForms provides an easy way to edit XML. In this article you will put the two together to create an XForms-based XVG editor for creating SVG images such as logos.

PHP is an easy to use scripting language often used in Web applications. PHP code is parsed and translated to opcodes every time it executes, but there is no need to translate the same PHP code each time. An opcode cache eliminates that rework, making PHP applications faster.

Take even greater advantage of the synergistic processing elements (SPEs) of the Sony PS3 in this installment of Programming high-performance applications on the Cell BE processor. Part 2 looks in depth at the Cell Broadband Engine processor's SPEs and how they work at the lowest level, while Part 1 showed how to install Linux on the PS3 and explored a short example program.

At times it is crucial to programmatically control the writability of data in your XForms. This tip shows how you can change the read-only property of controls programmatically. As data changes in your XForms form it can be essential to know and do something with the new data right away. This second tip shows you how to hook such events right into JavaScript methods to then use the data in many different ways.

With recent advances in frameless transparent windows for Linux desktop now you can use Perl, Ghosd, and some network programming to display on-screen overlays of text and graphics based on messages from your local system and remote computers. Define custom images, font sizes, and colors to convey information integrated with your desktop.

This article explores the Linux boot process from the initial bootstrap to the start of the first user-space application.
