- The document provides a history of Linux from its origins in 1969 with the creation of Unix through its evolution and growth over time.
- Key events include the creation of the GNU operating system in the 1990s, the development of the Linux kernel in 1991, and the combining of Linux and GNU to create a fully functional OS in 1992.
- Linux adoption grew steadily, reaching millions of users by the late 1990s and early 2000s as major companies began supporting it and distributions like Fedora and OpenSUSE were created.
- Today, Linux is widely used and accepted, powering over 80% of web servers and being utilized by many universities and entrepreneurs.

4. This session will split into 2 sections
The First section is intro to open source culture and the
history of Linux and its features.
The Second section is practical in which we will start the
festival with installing Linux on our machines and got your
free Linux CD
6. 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

8. Are You Ready To
Listen To The History
of Linux?
Ok, … let‟s GO
10. 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
11. 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.
12. 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.
13. 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
14. 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
15. 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.
16. 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.
17. 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.
19. 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.
21. Linus Travalds
1. 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.
24. • 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.
31. 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.
33. Many Linux Distributions Appear
This will discussed later in this Event
but for example we have:
(RedHat Linux, SuSE Linux, Debian, Turbo Linux,.. etc)
35. • 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.
40. • Red Hat splits into 2 versions
– RHEL - their enterprise/business version with
which you purchase support.
– Fedora – their home version with no
support.
42. • 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
44. 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.
54. Second step
Make sure that you have at least 8 GB free
space on your hard disk.
• We will make 2 GB for the swap Partition.
• And the other 6 GB for installing Ubuntu and
other Packages later.
55. Step 3
Put the Ubuntu CD into your CD Room.
Play it.
And Reboot your machine.
56. Note That
the Ubuntu will be loaded into the memory
and run as a life CD if you choose to try it
now as we will see in the practical view in
the next few minutes.
