2. What's SFD?
● Software Freedom Day (SFD) is a worldwide
celebration of Free and Open Source
Software (FOSS).

3. What will we talk about today
● Brief history about Free Software movement.
● Some Concepts
● FOSS in the future
● A strategic look

4. History of GNU
● Richard Stallman (RMS)
● A printer driver ??
● What's GNU? Gnu's Not Unix :)
● A project to stop companies
monopoly of our computers.

5. Linux
● Linus Trovalds, the finnish guy.
● Freax? No thanks, linux is better :)
● Initially a terminal emulator, then
a kernel.
● Tux, the official mascot.

7. Examples of FOSS
● OS: GNU/Linux
● Programming languages: C/C++, Ocaml, PHP,
Python, Ruby, Lua, .. etc
● Servers: Apache, MySQL, PostgreSQL, .. etc
● End user applications: Firefox,
OpenOffice.Org, VLC medial player, … etc

8. FOSS is not only in Software
● Wikipedia.org
● OSWD.org (OpenSource Web Designs)
● OpenCores.org (hardware)
● Open Cola
● Open Data ( scientific data)
● ChemCollective.org

9. Quote
● You can’t better the world by simply talking to
it. Philosophy to be effective must be
mechanically applied.
● Buckminster Fuller

10. Some Concepts
● Unix
● BSD
● GNU tools
● Linux kernel
● GNU/Linux
● GNU OS (GNU/Hurd, Debian GNU/Hurd)
● Debian GNU/kFreeBSD

11. Philosophy
● “Free software” is a matter of liberty, not price.
To understand the concept, you should think
of “free” as in “free speech,” not as in “free
beer.”
● Open Source is a development methodology;
Free Software is a social movement.
● http://www.gnu.org/philosophy/

12. 4 Freedoms
● The freedom to run the program, 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.

13. Licensing
● Copyleft.
● GPL: grants the 4 freedoms, with other stuff
too.
● CreativeCommons: where GPL can't be used.
● Others: BSD license, Apache license, … etc.

14. GNU/Linux Distributions
● It's an OS built based on Linux using GNU tools
and lots of other FOSS projects.
● Most famous ones currently are:
– Debian
– Ubuntu
– RHEL (RedHat) / CentOS
– Fedora
● Currently active arabic distro is Ojuba and Joatha,
the discontinued ones are alot, though.

15. FOSS Community & LUG
● If you didn't get it yet, free software can't be
made with individuals, it needs a big
community as it's based on code
contributions.
● Public recognition in such communities is a big
motive for lots of people.
● LUGs are local communities centered about
FOSS, like EGLUG.org (Egypt GNU/Linux
Users Group).

16. FOSS communities
in Egypt
● Linux Egypt
● EGLUG.org
● LinuxAC.org
● Ubuntu Egypt
● OSUM
● FSF arabia, will it happen someday?

17. Quote
● You never change things by fighting the
existing reality. To change something, build a
new model that makes the existing model
obsolete.
● Buckminster Fuller

18. Future of FOSS
● PCs:
– GNU/Linux is gaining ground, rising quickly in usability in the
last few years (which mainly was its drawback).
– Companies jumped in (Google Chrome OS).
● Embedded systems:
– Gaining ground as currently writing an OS especially for an
embedded system is not worth it in most of cases, simply
install linux in lots of current systems.
● Mobile devices:
– The next (or current?) hype for linux. Android is linux based.
But Maemo/Meego is the really interesting thing:
Linux+GNU+Debian stack+X+Gnome+QT

19. Quote
● First they ignore you, then they ridicule you,
then they fight you, then you win.
● Mahatma Gandhi

20. A Strategic look
● Our country is low on financial resources,
which doesn't give us lots of fields to success
at.
● If we look at the software field without the
FOSS, it's already dominated by big players.
We can't compete with them cause we don't
know the know-how of operating systems,
database engines, .. etc. All we can do is
some websites and somethings like that, but
we can't touch the core technologies.

21. A Strategic look (Cont'd)
● FOSS gives us the knowledge, and IT doesn't mainly
rely on big finance.
● If we tried to work with proprietary software, we will be
salesmen for the big players (For example who
creates a website using .net and SQL server, forces
his client to buy these licenses).
● The know-how gives us the ability to enhance the
current solutions and even create our own. So we
won't be limited to waiting for new releases of
proprietary software.
● We shouldn't be controlled by a certain company/entity.

22. What's in it for me?
● End user: better and cheaper software.
● Developer: very big learning resource, and
technologies in continuous development.
● An enterpruneur / business guy: dramatically
lower costs, having better customization,
more easy to create your own product or
provide your services.

23. Bottom Line
● You got freedoms, it's your right. Use them,
and ask for them.
● You can help, so please contribute.
● Free Software is a social movement, it's an
idea you can apply within your life outside the
software prespective.
