The term user rarely refers to a single biological unit. This is why you have security groups, as discussed in 23. As soon as you de ne or categorize the levels of user groups that you need to support in your organization, you can enforce change-management procedures on those groups. If you are involved in client management, you should make an effort to become a member of the change-control team. You should also get to know your users, the type of software and applications that they need, and how they work with their computers, treat their computers, and interact with their computers. You have two main types of user or worker, as described in the following list: Knowledge workers. Your knowledge workers are usually the workers who are applying a particular skill set or knowledge base in their job. These people are your engineers, technical-support people, accountants, lawyers, designers, and so on. Knowledge workers usually have a permanent of ce, and they use their computers for most of the day. Because their machines are constantly in use, losing them would be costly for the company. They can be considered advanced users. Task-oriented workers. These workers are data-entry personnel, receptionists, of ce assistants (to varying degrees), order takers, and so on. Most of these users would not need more than a terminal and a terminal service account to perform their duties. These users can be considered your basic users.

21, Web Server described the popular Linux Apache MySQL PHP (LAMP) web application environment in Ubuntu and showed how to use it to serve dynamic web pages to clients. The core of this technology is the PHP programming language. PHP started out as a personal project by Rasmus Lerdorf in the mid 1990s, but it quickly rose to the top of the dynamic web programming world because it was specifically designed for web programming. Unlike Perl, Python, and Ruby, which were originally designed as command-line scripting languages, PHP was designed to be run within web pages in a web application. The name PHP originally came from Personal Home Page because Rasmus intended for it to be used only on his own personal home page. Nonetheless, he released it into the open-source software world. Two developers (Zeev Suraski and Andi Gutmans) picked up the original code and rewrote it to form PHP version 3. The PHP initials were kept as part of the name, but the full name changed to PHP: Hypertext Preprocessor to more accurately identify the package. You ll notice that the term PHP appears in the definition itself. This practice is called recursive initialism, and it is common in the open-source world.

Multiple Mate mode enables you to select one face in order to mate multiple faces from other parts to it. Figure 13.5 shows the interface for this mode, which you can toggle to from the Mate PropertyManager interface. Multiple Mate mode is the paperclip with the lightning bolt icon without any text on it. This function works only with the Standard Mate types, not with any of the Advanced mates, which I discuss later in this chapter.
