The ICT-Business is known for strategic terms. One of those terms, which was used quite a lot over this year, is services. The term is interpretable; however, the focus was on technical concepts implemented to serve for a sharply rendered use case, like managing user data and authentication. Services in that sense are served over a type of network. Despite the first impression, they are not served to a user but to a calling application. This client utilizes one or more services for internal purposes. Though, the user may be expected to provide data (the password, for example) or to wait and receive a gathered result.

"Linux-VServer allows you to create virtual private servers and security contexts which operate like a normal Linux server, but allow many independent servers to be run simultaneously in one box at full speed. All services, such as ssh, mail, Web, and databases, can be started on such a VPS, without modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers." A guide for Debian is available here.

"This is a step-by-step guide (with screenshots) for configuring a virtual machine and installing on it Sun Solaris 10. At the end you'll be able to run the virtual machine inside Workstation 5.5 or inside VMware Player 1.0, which is a free virtualization product."

"For the last couple of years the community has been working to ensure that developers can create applications using Java without having to depend on proprietary software. Today, the Free implementations are already very capable and support a vast amount of functionality that developers expect from a Java-like environment. Important large applications like JOnAS, OpenOffice.org 2, Eclipse 3 and Tomcat 5 are known to work and now included in distributions like Ubuntu and Fedora Core. This document provides a road map of the various projects; how they work together, where they are, where they're going, and how we make sure that they work well and are compatible."

Marcus Zarra discusses Core Data, which is a new framework that was introduced by Apple with the release of OS X 10.4 Tiger. Core Data replaces the need for building data objects and helps manage storing data in a flat file, XML file or SQLite database. Marcus walks you through some of the basic usages of Core Data and tells you why it is so useful.

"In 2005, Apple announced the Mac Mini. It was the answer to what I was looking for in a computer, so I bought one. This is a report about the early months with my new Mac, and how it compares to a Linux computer (I have never owned a Windows computer). In short, I am now both a Mac and a Linux user - Apple gets GUI simplicity, usability, and coherency right, and Linux everything else."
