What does it mean:

• You can share open source programs• Develop in collaboration• Get better softwares, lesser bugs, more usability • For the people, from the people, by the people• You can create new business opportunities

GNU Public License or GPL

The freedom to use the software and have access to the source code.

The freedom to modify the software. The freedom to redistribute the software. The freedom to ensure that all modifications must be

redistributable.

Open Source Operating Systems Linux FreeBSD, OpenBSD, and NetBSD: The BSDs are all

based on the Berkeley Systems Distribution of Unix, developed at the University of California, Berkeley. Another BSD based open source project is Darwin, which is the base of Apple's Mac OS X.

Open Source for Internet Apache, which runs over 50% of the world's web

servers. BIND, the software that provides the DNS (domain

name service) for the entire Internet. sendmail, the most important and widely used email

transport software on the Internet. Mozilla, the open source redesign of the Netscape

Browser OpenSSL is the standard for secure communication

(strong encryption) over the Internet.categories.

Open Source Programming Tools Zope, and PHP, are popular engines behind the "live

content" on the World Wide Web. Languages:

Perl Python Ruby Tcl/Tk

GNU compilers and tools GCC Make Autoconf Automake etc.

Top Open Source Companies IBM

uses and develops Apache and Linux; created Secure Mailer and created other software on AlphaWorks

Red Hat Software Linux vendor

Some dates from the history of open source

1970s: UNIX operating system developed at Bell Labs and by a diverse group of contributors outside of Bell Labs; later AT&T enforces intellectual property rights and “closes” the code

1983: Richard Stallman founds the Free Software Foundation 1993: Linus Torvalds releases first version of Linux built 1997: Debian Free Software Guidelines released 1998: Netscape releases Navigator in source

• Lower total cost of ownership• Reduced dependence on software vendors• Easier to customize• Higher level of security• The availability of the source code and the right to

modify it is very important. • The right to redistribute modifications and

improvements to the code• The right to use the software in any way.

Advantages of Open Source:

Growth of Open Source Software

Growth of Open Source Software in Millions
