Sub-Zero Level The Guide before starting Linux (History & Install) Medhat DawoudMed7atDawoudMed7atDawoud www.medhatdawoud.com
This session will split into 2 sectionsThe First section is intro to open source culture and thehistory of Linux and its features.The Second section is practical in which we will start thefestival with installing Linux on our machines and got yourfree Linux CD
FLOSS• FLOSS = Free Libre Open Source Software.• This type of software uses a GPL or open source licences.• What it gives you? – Freedom to use – Freedom to examine – Freedom to redistribute – Freedom to modify• What it doesn’t let you do? – Deny these freedoms to anyone else
Linux History Timeline 1969 1990These are the most 1991effective years in Linux 1992 1993life the session will be 1997as a time line with 1998some interest 1999 2002 2003 2008 Today
Are You Ready ToListen To The History of Linux? Ok, … let‟s GO
What is Unix? • Unix was born. • Unix is an operating system. • Linux is a clone of Unix so we should know actually what is Unix and it‟s features. • The open source culture was found. • The GPL License was found by Richard Stallman
What is Unix? • The Internet was built on UNIX. – TCP/IP is a native UNIX protocol. – Today 80% of the worlds Internet Web servers are using Linux.
What is Unix? • Unix has commonly been used for the past 40 years. – It was created in 1969 - long before Microsoft existed. – It was the 1st worldwide commercial operating system.
What is Unix? Unix has always commonly been used on mainframes Today as “Linux” it is also commonly Being used on PC‟s as servers & desktop
Features in Unix• It was able to be run by various types of CPU‟s – Before Unix vendors commonly wrote their own Operating systems. – Which ran just on their own CPU’s and equipment. – Unix was written to be able to run on many different types of CPU’s
Unix was one of the first OS to supply: a simple user interface. simple utilities or commands that can be combined to perform powerful functions.
Unix was one of the first OS to supply: a permanent hierarchical file system. simple interface to connect new devices to the OS. multi-user functions.
Unix was one of the first OS to supply: multi-process system functions. which was architecturally independent. All of which was permanent and transparent to the user.
Richard Stallman• One of the people who started this “open” philosophy.• Has nearly completed his new GNU operating system based on the UNIX system. – He had most of the modules but was still missing the main part ! – The kernel.• He used C Programming language to write the code of GNU.
Linus Travalds1. Creates the Linux kernel based on the source code of Miniux which he studied at university.2. Choose the Penguin to represent his kernel.1. He did not write an entire operating system.2. When complete Linux kernel was released under the GPL license.3. He used C Programming language to write the Kernel.
• The Linux kernel is combined with the already created GNU modules & utilities and now becomes a fully useable operating system.• So you should know that nobody owns Linux and most of it‟s developments are made by unpaid volunteers.• And the distributions was starting opening.
Eric Raymond writes a paper called the „Catheral & Baazar‟ in which he analyzes the development &differences of the „proprietary‟ software model verse the „opensource‟ software models.– The article takes the IT industry by storm.– Eric Raymond becomes a front man for the new open source movement.– Netscape director reads the article and in direct response freely releases the source code of the Navigator software. • Netscape is the 1st large company to go opensource.
• Linus, Linux & the open source movement starts becoming commonly known. And gaining momentum.• Linus appears on TV.• On the front of the Forbes Business Magazine.• IBM, Oracle, Compaq, SAP + others announce their support for Linux.
Now Linux Users are about1.5 Million Linux Users
• Novell buys SuSE Linux for $210 million• IBM is now the most powerful backer of Linux. – To counterbalance the world of Linux they make a 50 million dollar investment in Novell. – SuSE becomes the major enterprise competitor to Red Hat. – SLES - their enterprise/business version with which you purchase support – OpenSuSE – their home version with no support
Today Linux has grown from being a hacker/home developed OS to being accepted world wide– It is highly regarded and runs many many major enterprises.– Many sites are now also using it on their client machines.– Over 80% of web servers run Linux.
Now Linux Users are about20 to 30 Million Linux Users
