LAMP is an acronym which stands for Linux, Apache, MySQL and PHP. The letter P also stands for Perl and Python programming languages. LAMP is a free software stack which powers, primarily, web servers. Most GNU/Linux distributions bundle these packages in the install media and repositories. Let us take a look at how to install LAMP using Fedora. I will restrict the P in LAMP to PHP only for this article. Perl and Python fans, bear with me. While installing Fedora you can choose to install "Web Sever" which contains these packages. You can install them later also. Let me walk you through the actual steps to get LAMP working on your computer. I assume you are running Fedora 8 on your computer. 1. Launch the terminal by clicking

Appendix K Unicode (on CD) 1499 To obtain more information about the Unicode Standard and the Unicode Consortium, visit www.unicode.org. It contains a link to the code charts, which contain the 16-bit code values for the currently encoded characters. Numerous programming languages provide some level of support for the Unicode Standard. In Java programs, the uyyyy escape sequence represents a character, where yyyy is the four-digit hexadecimal code value. The u0020 escape sequence is the universal encoding for the space character. TERMINOLOGY uyyyy escape sequence portability ASCII script block surrogate character symbol character set unambiguous (Unicode design basis) code value Unicode Consortium diacritic Unicode design basis double-byte character set (DBCS) Unicode Standard efficient (Unicode design basis) Unicode Transformation Format (UTF) encode uniform (Unicode design basis) escape sequence universal (Unicode design basis) glyph UTF-8 hexadecimal notation UTF-16 localization UTF-32 multi-byte character set (MBCS) SELF-REVIEW EXERCISES K.1 Fill in the blanks in each of the following. a) Global software developers had to their products to a specific market before distribution. b) The Unicode Standard is an standard that facilitates the uniform production and distribution of software products. c) The four design basis that constitute the Unicode Standard are: , , and . d) A is the smallest written component the can be represented with a numeric value. e) Software that can execute on different operating systems is said to be . K.2 State whether each of the following is true or false. If false, explain why. a) The Unicode Standard encompasses all the world s characters. b) A Unicode code value is represented as U+yyyy, where yyyy represents a number in bi nary notation. c) A diacritic is a character with a special mark that emphasizes an accent. d) Unicode is portable. e) When designing Java programs, the escape sequence is denoted by/uyyyy. SELF-REVIEW ANSWERS K.1 a) localize. b) encoding. c) universal, efficient, uniform, unambiguous. d) character. e) portable.
348 Part II . Getting Around in Linux Screen The XF86Config file lets you specify multiple video cards and monitors. The Screen section is used to match up the different video cards to the monitor definitions. Table 9-6 shows the possible entries for this section. The following is an example: Section Screen Driver accel Device My Video Card Monitor Gateway EV700 Subsection Display Depth 32 Modes 1152×864 ViewPort 0 0 EndSubsection EndSection In the If you receive an error when starting X saying that no screens are useable, make Real World sure the specified monitor is capable of using the requested resolution with the defined video card. Table 9-6 Screen Section Entries Entry Function Driver Driver Name Each Screen section begins with this entry. It tells the system which X server, or which driver in an X server, to load for this screen. Device Device ID Specifies which video card identifier string to use for this screen. This is how the video card is matched up to the monitor. Monitor Monitor ID Specifies which monitor identifier string to use for this screen. This is how the monitor is matched up to the video card.
