LINUX (LIH- nuks ) Unix Originally developed at AT&T as a multitasking system for minicomputers and mainframes in the 1970’s. Linux Developed primarily be Linus Torval. Inspired by Minix. Kernel uses no code from AT&T or any other proprietary source. Developed by a group of volunteers, primarily in the Internet, who exchange code, report bugs and fix problems.
What is so special about Linux. Linux is said to be: Reliable. Simple. Free! Runs on a variety of platforms. considered the most important free software achievement. Able to turn any or better PC into a workstation.
LINUX Features: Complete multitasking, multiuser OS. Compatible with Unix standards. Supports virtual consoles. Supports various file systems for storing data. Provides complete implementation of TCP/IP networking software. Include device drivers for many Ethernet cards.
LINUX Features (cont.) Kernel is developed to use protected-mode features of Intel and better processors. supports demand-paged and loaded executables. supports copy-on-write pages. Linux can coexist with other OS on the same machine.
GNU/Linux K Desktop Environment KDE is a powerful GUI desktop environment for Unix workstations. Provides ease of use, contemporary functionality, and the technological superiority of the Linux OS. KDE is an internet project that is "Open" in every sense. All KDE sources are open to everyone and may be distributed by anyone subject to the well know GNU licenses. KDE is a mature desktop suite. Visit for further information.WWW.KDE.ORG
The GNU Project Launched in 1984 to develop a completely Free Unix- like operating system: The GNU System. Many flavors of the GNU system are currently in use, i.e. Caldera, Redhat, Corel, etc. These GNU Systems use the Linux Kernel, these systems are incorrectly called "Linux", they should be called GNU/Linux systems. GNU is "Copylefted". Copyleft uses copyright law in reverse. It allows software to be used, modified, and distribute modified versions. Modified versions may not add restrictions of their own. Visit for more information.www.gnu.org
Current KDE Distribution Includes the following packages: KDE-Libs: Various Run-time libraries KDE-Base: The base components KDE Graphics: e.g. Kpaint, Kfax, Kghostview KDE Utilities: Kedit, KCalc, Knotes KDE-Multimedia: KMidi, Kmodplayer, Kmixer, KSCD KDE-Games: Kasteroids, Kpat, Ktetris KDE-Admin: Various rools to aid system administration
Current KDE Distribution Includes the following packages: KDE-Network: Kppp, Krn, Kmail Most current distributions of Linux Use a modified version of KDE. Corel calls its version Enhanced KDE. Visit Linux.Corel.com, Linux.com, Linuxworld.com for more information. Demonstration.
The Value of Linux Application Linux is a complete multitasking, multi-user operating system. It supports various file system and applications. Linux is much more compact and runs similar applications much faster than Windows.
Lower Cost Most of Linux software and applications are inexpensive, which you can purchase in diskette or CD-ROM format. E.g. CorelDraw, WordPerfect 8, Domino R5, games, etc…. Linux is free and easily downloaded from the internet, or can be purchased at a much lower cost than Windows software.
Ease of Operation Corel Linux has an Update wizard which can install more recent versions automatically. Use Corel update to remove applications that you no longer want to use. Reinstall deleted applications at any time.
Init Runlevels 0 -- Halt level 1 -- Single user mode 2 -- Multiuser mode (with no shared resources) 3 -- Full Multiuser mode 4 -- Not used 5 -- Full Multiuser mode (with X-based login screen) 6 -- Reboot
Init Program’s Main Roles It creates processes, which has the effect of bringing the system up to the default run level. It controls transitions between run states by re-reading the inittab file.
Inittab File Defines The system’s default run level What actions to be taken when the system enters a new run level What processes to start, monitor, and restart if they die
Run Control Scripts The scripts for starting and stopping system services are located in the rcR.d directories, where R is the run- level. Files that start with S are used to start processes. Files that start with K are used to kill processes.
Init.d Directory The start and kill files in the rc#.d directories are hard linked to scripts in the init.d directory. This is done to facilitate booting. An important advantage of having the actual run control files in the init.d directory is that you can start and stop individual processes from a single location without changing run levels.

LINUX Multimedia Mark’s Linux Application List - Multimedia Well, Linux is a multitasking OS, so it's a perfect OS for multimedia. AuMixer Console-mixer tool. For: Does everything that you've expected! Against: Nothing Get it NOW at: Related:http://jpj.net/~trevor/aumix.html B-play Sound player, pretty good. For: Small Against: Nothing Get it NOW at: ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Related:ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Cthugha This is a Linux port of the Dos program CTHUGHA (well, funny name, indeed). It's an entertaining application that will grab sound (from for example a CD) and display visual effects on the screen. While playing the audio. Not so useful, but, cool :). For: Amazing Against: I want more and smoother colors in the effects Get it NOW at: Related: ftp://sunsite.unc.edu/pub/Linux/apps/sound/lightshow/http://www.afn.org/~cthugha/ftp://sunsite.unc.edu/pub/Linux/apps/sound/lightshow/
Cont. Funktracker Gold The only Tracker (MOD-maker) for Linux...until Maube (look under) will be released. But it's not as good as (for example) FastTracker II. I hope they will update it... For: The only alternative (yet) Against: Ugly, disabilities Get it NOW at: ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Related: MikMOD Regular MOD player, plays most of the MOD-file types - in the way YOU wish. You can also get a X- Interface (haven't tested). For: Good MOD player Against: Nothing to say Get it NOW at: Related:ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/http://www.tohs.abacom.com/mikmod/ MiXViews Oh!

Against: Increasing the volume during startup, why not some more effects?
