Folks, it's simple. We are not Red Hat.

Welcome to the next step in studying for the Linux certification exams. This tutorial series serves as a comprehensive study guide so you can take the exams with confidence. In this tutorial (the third in a series of five tutorials), Ian Shields introduces you to the Linux command line and several GNU and UNIX commands, and in doing so, continues preparing you to take the Linux Professional Institute Junior Level Administration (LPIC-1) Exam 101.

The IBM Full-System Simulator has been developed in conjunction with many large-system design projects built upon the IBM Power Architecture. As an execution-driven, full-system simulator, it has facilitated the evaluation of a variety of system components for core IBM initiatives, such as the STI Cell and the IBM PERCS projects.

You don't need to debug Java applications on just your local desktop. Learn how to spread around your debugging using different connection types that make up remote debugging. This article explains the features and examples that show how to set up remote application debugging.

The Eclipse Plug-in for Generating and Executing Test Cases for Database Objects enables users to automatically generate JUnit or SQLUnit test cases for database objects. By using defined code templates and parameter templates, the repetitive effort of handling the objects is significantly reduced. This tool contains a friendly user interface for test case generation, execution, and test result verification.

To build an available Linux server environment with IBM blades, first you need to set up a fault-tolerant environment between the blade and any external storage. This enables you to deliver redundancy and enable multipathing. In this article, learn how to integrate an x86-based IBM BladeCenter server and external IBM BladeCenter Boot Disk System SAS storage, as a critical prerequisite for a reliable Linux/blade server environment.

AIXPert is an all-purpose GUI and command-line security tool that incorporates over 300 security configuration settings. Learn about recent enhancements implemented with IBM AIX V6.1, including SOX auditing support, and go through real scenarios to show how AIXPert can be used from the command line, smit, and the GUI.

Capture and distribute rich media content consisting of video, audio, and slides from the originator's computer to multiple clients with Personal Presenter. The control is easy: a presentation can be started with a single click. This technology allows configuration of some key parameters, such as video size and still-image capture rate. The graphical user interface is written in Java, and the underlying functionality is implemented in C/C++.

Follow along in this "What's new in PHP V5.3" series of articles that covers the new features found in PHP V5.3. Part 1 looks at the changes made to the object-oriented programming and object handling in PHP V5.3. Here in Part 2, we look at closures and lambda functions. They are designed to make programming easier by allowing you to define throwaway functions that can be used in many contexts.

Guice is Google's open source dependency injection framework for Java development. It enables better testing and modularity by taking away the pain of writing your own factories. This article offers a tour of the most important Guice concepts that will leave you ready to Guice up your applications.

Many sophisticated machine learning algorithms cannot process large amounts of data on a single node, but Parallel Machine Learning Toolbox (PML) can do so by distributing the computations. This distribution speeds up computations and expedites training by weeks, days, or even hours in an easy, reliable way. PML can run on a wide array of architectures including single-node, small clusters, grids, and BlueGene.

This collection of how-to guides, demos, and articles will help you sharpen your skills around the range of implementation technologies needed during all phases of application development cycle.

Every day people rely on search engines to find specific content in the many terabytes of data that exist on the Internet, but have you ever wondered how this search is actually performed? One approach is Apache's Hadoop, which is a software framework that enables distributed manipulation of vast amounts of data. This article introduces the Hadoop framework and shows you why it's one of the most important Linux-based distributed computing frameworks.

Apart from its use as a powerful Web application development platform, in combination with the Rails framework Ruby is also a powerful scripting language. It has immense capabilities, owing to the availability of many built-in and external libraries, the power of which can be harnessed to solve a great deal of the scripting needs that surface in typical systems administrative work environments.

Context-Sensitive Spelling Checker (csSpell) is a spelling checker that examines words and their context to detect potential misspellings instead of using a spelling dictionary. csSpell can scan plain text files; files that contain non-text elements such as SGML, HTML, or XML tags; and even files that contain program code.

The W3C XML Schema working group has developed XML Schema 1.1 to address the most commonly requested features including several which address shortcomings of XML Schema 1.0. In this first of a multi-part series of articles, XML Schema 1.1 is introduced with an overview of the features in this emerging standard.
