You say you prefer to work in Linux? It doesn't mean you have to be left out of the freedom wireless computing brings you. In this tutorial learn how to configure a wireless network card under Linux. At the end of the tutorial you'll know how to set up a Linux laptop for wireless transmission using Gentoo distribution as an example.

Business users who have no programming skills can use IBM Development Engagement Service to create online forms. It is an online service providing an Ajax-based development environment that enables business users to visually develop form applications.

Most of Ajax applications use XML to transfer information to and from the server, so your application must be able to parse and create XML data. This tutorial shows you how to manipulate and create XML using the Google Web Toolkit. This toolkit enables you to use Java syntax to create the JavaScript necessary for Ajax user interfaces.

Use the PA technology's Time Base register to measure time at the nanosecond level in Linux on PowerPC and Cell BE microprocessors. Applications where this is useful include timestamping transactions (typically encrypted or digitally signed single-use messages), profiling code, and implementing small, precise software delays.

Learn how to install multiple Linux servers at the same time using network-based installation. In this second article of two parts on installing Linux server software, understand how to configure and install using Network File Share (NFS) on System x with Red Hat Enterprise Linux Version 4.

Applications using the LAMP architecture, such as Linux, Apache, MySQL, and PHP/Perl, are constantly being developed and deployed. This first article in a series of three covers the LAMP architecture, some measurement techniques, and some basic Linux kernel, disk, and file system tweaks. This series of three articles discusses many of the server configuration items that can make or break an application's performance.

Virtualization with VmWare, Xen, and Kernel-based Virtual Machine (KVM) are all the rage these days. But did you know that you can run Linux cooperatively with Microsoft Windows? This article explores Cooperative Linux (coLinux), starting with a quick introduction to virtualization and then looking at the approach taken by coLinux.

Enable Web client to directly access server-side relational data without compromising enterprise security with IBM Database Connectivity for JavaScript. Web 2.0 applications can thus use this to access relational data as a first-class construct instead of through ad hoc protocols.

Python has greatly increased its number of syntactic features and built-in functions and types, making it no longer a language that experienced programmers can pick up "in an afternoon." This article discusses the new features that have been added to Python, and weighs in on which ones are truly valuable and which just add unnecessary complication.

Second Life is a virtual world, maintained through a combination of client software and hosting servers. The open source release of the Second Life viewer program by developer Linden Lab offers a rare opportunity to compare strengths of closed and open source development models. This article, the first in a series, gives an overview of some of the differences between these development styles.

WAS CE is a J2EE 1.4-certified application server that provides support for Plain Old Java Object (POJO) and Enterprise JavaBeans (EJB) Web service endpoints. This tutorial shows you how to use Eclipse Web Tools Platform (WTP) to create an enterprise application that implements POJO and EJB, using DB2 Express-C as the database for the application.

This article walks you through the initial steps involved in creating an Eclipse-based application using the Graphical Editing Framework (GEF). Also, discover the options you have these days to bootstrap the process of creating graphical editors in Eclipse.

IBM Trace and Request Analyzer for WebSphere Application Server allows you to find delays and possible hangs from WebSphere trace files and HTTP plug-in traces by parsing call trees of methods and traces and calculating delays in each method and trace.

In Part 5 of this series about programming on the Cell BE processors, apply your knowledge of the synergistic processing unit (SPU) to programming the Cell BE processor in C/C++. Learn how to use the vector extensions, direct the compiler to do branch prediction, and perform DMA transfers in C/C++.

Simplify the creation and deployment of MapReduce programs with IBM MapReduce Tools for Eclipse, a plug-in that can runs on Linux, Windows, or any system that can run Eclipse. It uses the Hadoop open-source MapReduce framework, which enables data-intensive applications to run on large clusters of commodity hardware.

Learn how to install and configure Red Hat Enterprise Linux 4 on IBM standalone rack servers. The examples illustrate installation on x86 systems, but the examples can apply to a variety of hardware architectures, including x86_64, IA64, S/390, and ppc64.

Build integrated development environments (IDEs) with Eclipse 3.2.0 on HP-UX Itanium platform, which can be use to create applications as diverse as Web sites, embedded Java(TM) programs, C++ programs, and Enterprise JavaBeans.

Linux system calls -- we use them every day. But do you know how a system call is performed from user-space to the kernel? Explore the Linux system call interface (SCI), learn how to add new system calls (and alternatives for doing so), and discover utilities related to the SCI.

Need to consolidate your servers? Or maybe you are trying to set up a test environment that needs to be completely isolated from the production environment.
