This document provides an introduction to open source software and the history of Linux. It discusses how GNU and Linux were created to provide free and open source alternatives to proprietary operating systems like DOS, Mac OS, and UNIX. Key events mentioned include the founding of the GNU project in 1984, the development of the Linux kernel in 1991, and its rapid growth through collaborative development. The document also outlines some popular Linux distributions, free software principles, and proposes a course on Linux system administration and programming languages through Code4VN.

Only for minicomputer for commercial applications ▸People was looking for a UNIX based system, which is cheaper and can run on PC ▸Both DOS, MAC and UNIX were proprietary, i.e., the source code of their kernel is protected ▸No modification is possible without paying high license fees
- 6. TEXT GNU: GNU’S NOT UNIX ▸ GNU STANDS FOR(GNU’s NOT UNIX) ▸ Established in 1984 by Richard Stallman ▸ He believes that software should be free from restrictions against copying or modification in order to make better and efficient computer programs.
- 7. TEXT BEGINNING OF LINUX ▸A famous professor Andrew Tanenbaum ( Vrije Universiteit, Amsterdam) developed Minix, a simplified version of UNIX that runs on PC ▸Minix is for class teaching only. No intention for commercial use ▸http://www.minix3.org/ ▸now BSD license
- 8. TEXT FOUNDER OF LINUX ▸ In sept 1991, while attending the University of Helsinki , Torvalds ▸ became curious about operating systems ▸ frustrated by the licensing of MINIX, which limited it to educational use only. ▸ He began to work on his own operating system which eventually became the Linux kernel.
- 9. TEXT GROWING AND GROWING… ▸In order to encourage wide dissemination of his OS, Linus made the source code open to public. ▸At the end of 1992 there were about a hundred Linux developers. ▸Next year there were over 1,400 developers representing over 200 corporations.. And the numbers multiplied every year. ▸The kernel which forms the core of the Linux system is the result of one of the largest cooperative software projects ever attempted. ▸http://www.linuxfoundation.org/publications/linux-foundation/who- writes-linux-2015
- 10. TEXT LINUX TODAY ▸Linux has been used for many computing platforms ▸PC, Mobile, PDA, Supercomputer,… ▸Not only character user interface but graphical user interface is available ▸Commercial vendors moved in Linux itself to provide freely distributed code. They make their money by compiling up various software and gathering them in a distributable format ▸Red Hat, Ubuntu, Suse, Slackware, etc
- 11. TEXT LINUX COUNTER At this moment, there are 573,971 users and 161,526 machines registered. https://www.linuxcounter.net/
- 12. TEXT LINUX – A FREE SOFTWARE ▸ The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom and to defend the rights of all free software users. ▸ Free software is a matter of liberty, not price. Think of “free” as in “free speech”, not as in “free beer”. ▸ Means users of a program have the 4 essential freedoms:
- 13. TEXT FREE SOFTWARE FOUNDATION ▸ The freedom to run the program as you wish, for any purpose (freedom 0). ▸ The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this. ▸ The freedom to redistribute copies so you can help your neighbor (freedom 2). ▸ The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.
