  1. Overview of Linux A presentation for IGGC1103 By 1- Ahmed alsaqqa 2- Aymanaburukhaya University Of Palestine MISS : RashaAtallah

  2. Linux was created by Linus Torvalds (hence, the name) in Helsinki, Finland. He was in his early years of university studies in Computer Science, when he created this operating system.

  3. Linus Torvalds selected Larry Ewing’s creation of Tux, the Linux penguin, as the logo or mascot.Ewing generously gave his creation for the promotion of Linux. Thank you Larry for sharing me with the world.

  4. Linux is the movement to open source software. Instead of closed software, it allows the software to be distributed freely.

  5. However, Linux truly began from the inspiration of a brilliant man: Richard Stallman

  6. Who is Richard Stallman? Founder of the Free Software Foundation in 1985, for the GNU Project. Wrote the free software license called the GNU General Public License (GNU GPL). His goal was to provide an alternative to proprietary software.

  7. General Public License (GPL) granted users rights to: • Run the program for any general purpose. • Study, modify and/or improve the program to suit personal needs. Access source codes are needed prior to such action. • Redistribute copies of program to the public at no cost.

  8. With that being said… Linus Torvald decided to adopt the GNU GPL to his creation of Linux. His creation began in 1991. He first created Linux version 0.02, from inspiration of his Minix Unix system that he was running at the time. By 1994, Linux Kernel Version 1.0 was released.

  9. Adoption of Linux • Linux’s availability and functionality have won the hearts of both commercial and non-commercial users. Many have adopted this open source system as their home and office desktop operating system.

  10. Companies that run Linux servers include… Visit www.sourceforge.net for a comprehensive list of open source projects and participants.

  11. Linux Today High profile adoptions: • French Police • French Parliament • City of Munich • Amazon • Google • Dreamworks (to produce Shrek)Preinstalled: • Sub notebooks: EEE & OLPC • £99 laptop • Dell • Server hardwareBetter support for Linux users

  12. Linux on the desktop • Different desktop systems available • Choose the one you like the best! • Can adapt to Mac & Windows styles of operation

  13. Why Choose Linux? Linux operating system uses a graphical user interfacethat is similar toother proprietary operating systems. (example: Microsoft XP or Mac OSX)

  14. Linux vs. Windows

  15. There is a catch. • Any modifications made to any programs must be released to the public. This is known as “Copyleft” • According to Richard Stallman, software developers have the right to make changes, share codes, use and redistribute, but are not bound to give away any derived work.

  16. Edubuntu • A version of Ubuntu aimed at schools • Able to use thin clients • Makes use of older hardware

  17. Case Study: OLPC Background: "Most of the nearly two–billion children in the developing world are inadequately educated, or receive no education at all. One in three does not complete the fifth grade." Why do they use Linux? “Linux...holds the promise of long-term sustainability by the local community—and, being free and open. The opportunity for local capacity-building abounds.” • Hardware designed for tough environment • Features radical Sugar UI: “since the laptop will be the first experience of computing for many children, activities do not have to be overly true to legacy behaviors or expectations. This frees developers to innovate.”
