  1. Winelfred G. Pasamba Dec 9, 2005 Finster Hall Adventist University of the Philippines Nov 6/7, 2007 De La Salle Canlubang Introduction to Linux

  2. Intro to Linux Outline • Goals of this seminar • How does Linux benefit you? • What is Linux? • Linux for big systems • Linux for personal computers • Scribus, Audacity, Edutainment, Personal Accounting

  3. Goals of this Seminar • Educate about benefits of Linux • Teach how to recover files from a bogged down computer with a Linux LiveCD • Help users understand Intellectual Property Issues • Give users more software options to choose from

  4. How does Linux Benefit You? • Not prone to virus and spyware • Because of LiveCDs • Linux not likely target of spyware and viruses because: • Most linux users are smart (not foolable into clicking social engineering advertisements) • Linux security bugs are quickly fixed within hours • Only few people use Linux compared to Windows

  5. How does Linux Benefit You? • Use Linux for data recovery • When your OS crashes, use a Linux liveCD to copy your files to a safe place before reformatting • Don't need to pay for sofware • Free. Most software in Linux distributions are put under the GPL, Artistic License, and the like • You can do anything, but don't hide the source

  6. How does Linux Benefit You? • Lower hardware costs • Some linux distributions (like Puppy Linux) can run productively with a Pentium 166 with 64MB of RAM and 300mb harddisk, boottime < 30sec • Linux Terminal Server Project (LTSP) • For computer labs, internet cafes • “thin-client”, all programs run in the server • Reduces a lot of maintenance time

  7. How does Linux Benefit You? • No need to use pirated software • Software is intellectual property (IP) of individuals or companies. • License is “grant to use” software • Read the License Agreement of your software • Linux saves us by being a free alternative to expensive software. GPL • GPL says you can do anything as long as you don't hide the source

  8. Our Interest In Educating You About Linux • We are not forcing you to use Linux or forcing you to stop using Windows, • Or judge which is better than the other, • We show you the benefits, but the choice is yours. • We hope you can be able to use both for your needs.

  9. What Is Linux? • A complete computer sofware set • Wordprocessors • Spreadsheets • Presentation Makers • Desktop Publishing Programs • Educational Games • Web Browsers • Instant Messengers and Chat Software • A lot of utilities

  10. What Is Linux? • A complete Operating System • Hardware drivers • Networking • File sharing • Programming (C#/.net, php, java, c, c++, perl, lisp, pascal, jsp, asp,...) • Servers (web, dns, dhcp, ftp, samba, novell, nfs, X, etc...)

  11. What Is Linux? • An Operating System Kernel • Loadable modules • Virtual memory management • Filesystems • Security • Threading • Symmetric Multi-Processing • Process, Memory, and IO Protection

  12. What Is Linux? • A project of Linus Torvalds as a student in Helsinki University, Finland • Many programmers around the world contributed code to Linux. • Many companies, individuals, and groups, compile the Linux code and bundle it with other free software. These are called “Distributions”. • Ubuntu, CentOS, RedHat, Puppy, Knoppix, SuSe, Xandros, etc...

  13. Distributions • RedHat – one of the first most successful • Mandriva – plenty of applications • Ubuntu – most user-friendly • Knoppix – popularized the liveCD idea, installable to harddisk, lots of applications, automatic hardware detection and configuration

  14. Distributions • Puppy Linux – for legacy computers • Xandros – commercial, tries to make windows-to-linux transition easy • Debian – basis for Knoppix and many other distros • Slackware – only for the bravehearted • Hundreds of more...

  15. What are Other Options? • Microsoft Windows • Best for end-users, virus/spyware prone, great set of compatible software base, not free • Microsoft Office • Best office suite, fastest, expensive • FreeBSD • Used by Yahoo servers, free

  16. What are Other Options? • OpenBSD • Most secure, great networking (packet filter) • Solaris • For big machines • Mac OS • Best combination of artistic and technical design • Others (IRIX, AIX, BeOS, ... DOS)

  17. Linux Compared to Other Options • A lot of applications compared to other free OSes • Compatible with a wide selection of hardware compared to other free Oses • Is free compared to Microsoft Windows • You can copy, install, to as many machines as you want • Stability (runs for days, weeks, months, without a crash or hang)

  18. Linux for Complex Systems • Google uses more than 20,000 Linux servers • AOLIS uses Linux for almost everything • AUP Cafeteria System is a Linux System • Shopwise POS is Linux also • Scooby-Doo, by Warner Brothers, was created using Linux render machines

  19. Linux for Personal Computers • Scribus – desktop publishing • Audacity – multi-track recording • Edutainment • Accounting - gnucash, grisby • OpenOffice • Firefox, GAIM, GIMP
