Do you know what to do when the performance of your UNIX network and the speed at which you can transfer files or connect to services suddenly comes to a stop? How do you diagnose the issues and work out where in your network the problems lie? This article looks at some quick methods for finding and identifying performance issues and the steps to start resolving them.

ICEfaces, an integrated Ajax application framework, enables Java Platform, Enterprise Edition (Java EE) application developers to easily create and deploy thin-client, rich Internet applications in pure Java code. This tutorial describes how to develop Web applications using JSF, Google and the translation option.

Real-time Java™ combines ease of programming in the Java language with the performance required by applications that must conform to real-time constraints. Extensions to the Java language provide features for real-time environments that are lacking in the traditional Java runtime environment. This article, the first in a three-part series, describes some of these features and explains how you can apply them to enable real-time performance in your own applications.

Google Web Toolkit (GWT) lets you use the Java™ language to implement rich client user interfaces that run in a browser. In this two-part article, David Geary brings you up to speed on the latest version of GWT and shows you how to implement a desktop-like Web application.

With the Linux virtual file system switch (VFS), you can create file systems on a variety of devices, from traditional disk, USB flash drives, memory, and other storage devices. You can even embed a file system within the context of another file system. Discover what makes the VFS so powerful, and learn its major interfaces and processes.

There's a lot more to text manipulation than cut and paste, particularly when you aren't using a GUI. This article introduces you to text manipulation on Linux using filters from the GNU textutils package. By the end of this article, you will be manipulating text like an expert.

GMaps4JSF, a JavaServer Faces (JSF) mashup library, integrates Google Maps with JSF. Using GMaps4JSF, you can construct complex street view panoramas and maps with just a few JSF tags. This article explains how to configure GMaps4JSF inside JSF 2.0 applications, and includes a brief introduction to JSF 2.0 Ajax.

GUIs are fine, but to unlock the real power of Linux, there's no substitute for the command line. Get to know some of the major features of the bash shell. By the end of this article, you will be comfortable using basic Linux commands like echo and exit, setting environment variables, and gathering system information.

Learn the nuts and bolts of why Java persistence in the current preview release isn't quite ready for prime time, while also getting a working demonstration of what you can do to persist data in the Google App Engine for Java applications.

Monitoring system logs or the status of a command that produces file or directory output are common tasks for systems administrators. Learn how to use two popular open source tools simplify these activities for modern systems administrators: the multitail and watch commands.

Learn how to use the new toString() code-generation ability in Eclipse Galileo along with hashCode(), equals(), and setter/getter generation to cut down on the amount of work that goes into building the foundation of a Java class. learn which code you have to type and which code you can generate, making a lot less work for you.

The Beagle Board is an open-hardware single-board computer that is both inexpensive and capable of running Linux at a reasonable speed. Get to know the Beagle Board, and learn how to get a Linux development environment together on the cheap.

Active Memory Sharing (AMS) is an enhancement to IBM's PowerVM virtualization technology available on the POWER6 platform. This article describes how to configured Active Memory Sharing on AIX. It also touches on performance considerations with AMS and gives you a better understand of how AMS interacts with the virtual memory.

WS-Security for SOAP Web services doesn't have to be an all-or-nothing proposition. By configuring WS-Security at the operation or message level, you can apply an appropriate degree of protection. This article takes a look at granular WS-Security in Web Services Description Language (WSDL) using Apache Axis2 and Rampart.

Distributed version control systems (DVCSs) offer a number of advantages over centralized VCSs, and for Subversion users looking to explore this model, Git is a great place to start. Using Subversion as a baseline, this articles shows how to install Git, set up a remote repository, and begin using basic Git commands.

The venerable master boot record (MBR) partitioning scheme can't fully handle disks larger than 2TB. With 1TB-hard disks now common and 2TB-disks becoming available, forward-looking individuals are thinking about alternatives to the MBR partitioning scheme. The heir apparent is the GUID Partition Table (GPT). Learn how to make sure your Linux system is fully prepared for the future of disk storage.

UNIX has hundreds if not thousands of commands, and it's impossible to remember every option and nuance. But, happily, you don't have to: man, UNIX's built-in, online reference system, is man's best friend. Take a look at this shortcut guide to the UNIX man pages system.

Your application can maintain fast processing times while still supporting some degree of data integrity and consistency — but you need to be aware of the trade-offs involved. Learnhow to implement a transaction strategy for high-performance applications.
