GNU: GNU’S NOT UNIX
▸ In 80’s, Microsoft’s DOS was the dominated OS for PC
▸Apple MAC was better, but expensive
▸UNIX was much better, but much, much more expensive. 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
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.
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
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.
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.

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

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:
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.

▸Do you know Restful, JSON, XML
▸Visual Studio, Eclipse, XCode, Notepad++…
▸YOU NEED TO KNOW A LOT BEFORE YOU CAN DO ANYTHING
TEXT
YOU CAN OPEN SOURCE
▸First: Copy code
▸Second: Learn code
▸Third: Think about code
▸Forth: Write own code
▸Fifth: Share your code
▸And… copy code… learn code … think… write… share… so on
