One argument you hear regularly against Linux is that there are too many different distributions, and that by having multiple distributions, there is fragmentation This fragmentation will eventually lead to different versions of incompatible Linuxes This is, without a doubt, complete nonsense that plays on FUD (fear, uncertainty, and doubt) These types of arguments usually stem from a misunderstanding of the kernel and distributions However, the Linux community has realized that it has grown past the stage of informal understandings about how things should be done As a result, two major standards are actively being worked on The first standard is the File Hierarchy Standard (FHS) This is an attempt by many of the Linux distributions to standardize on a directory layout so that developers have an easy time making sure their applications work across multiple distributions without difficulty As of this writing, Red Hat is almost completely compliant, and it is likely that most other distributions are as well The other standard is the Linux Standard Base Specification (LSB) Like the FHS, the LSB is a standards group that specifies what a Linux distribution should have in terms of libraries and tools A developer who assumes that a Linux machine complies only with the LSB and FHS is almost guaranteed to have an application that will work with all Linux installations All of the major distributors have joined these standards groups This should ensure that all desktop distributions will have a certain amount of common ground that a developer can rely on From a system administrator s point of view, these standards are interesting but not crucial to administering a Linux network However, it never hurts to learn more about both For more information on the FHS, go to their web site at wwwpathnamecom/fhs To find out more about the LSB, check out wwwlinuxbaseorg.

Figure 14-10. The generated number will stay on the LCD screen until the left button is pressed. Figure 14-10 shows that I ve selected Text as the Action for the DISPLAY block. For this first DISPLAY block, I ve also left the Display setting checked (to clear the LCD screen).

These components are all lightweight, which means that they are all derived from JComponent Also discussed is the ButtonGroup class, which encapsulates a mutually exclusive set of Swing buttons, and ImageIcon, which encapsulates a graphics image Both are defined by Swing and packaged in javaxswing One other point: The Swing components are demonstrated in applets because the code for an applet is more compact than it is for a desktop application However, the same techniques apply to both applets and applications

In this chapter, we discussed Linux s command-line interface through BASH, many command-line tools, and a few editors As you continue through this book, you ll find many references to the information in this chapter, so be sure that you get comfortable with working at the command line You may find it a bit annoying at first, especially if you are used to using a GUI for performing many of the basic tasks mentioned here but stick with it You may even find yourself eventually working faster at the command line than with the GUI! Obviously, this chapter can t cover all the command-line tools available to you as part of your default Linux installation It is highly recommend that you take some time to look into some of the reference books available For a helpful but less comprehensive approach to the considerable detail of Linux systems, try the latest edition of Linux in a Nutshell (various editions for different systems, from O Reilly and Associates) In addition, there is a wealth of texts on shell programming at various levels and from various points of view Get whatever suits you; shell programming is a skill well worth learning, even if you don t do system administration And above all else, RTFM, that is, Read the fine manual (documentation)

JLabel is Swing s easiest-to-use component It creates a label and was introduced in the preceding chapter Here, we will look at JLabel a bit more closely JLabel can be used to display text and/or an icon It is a passive component in that it does not respond to user input JLabel defines several constructors Here are three of them: JLabel(Icon icon) JLabel(String str) JLabel(String str, Icon icon, int align)
