What is Open Source Software?

What is Free Software?

The Godfather of Free Software:Richard M Stallman (rms)

Founded the GNU (GNU’s Not Unix) project in 1983 in response to being denied access to source code for an early laser printer driver

Founded the Free Software Foundation in 1986Wrote the General Public License (GPL) v1 in

1989, v2 in 1991Author of the GNU compiler (gcc), emacs and

several more

Definition of Free SoftwareRichard Stallman’s “4 freedoms”: Run the program, for any purpose (freedom 0)Study how the program works, and adapt it to

your needs (freedom 1)Redistribute copies so you can help your

neighbor (freedom 2)Improve the program, and release your

improvements to the public, so that the whole community benefits (freedom 3)

General definition of open sourceBruce Perens created the Open Source

Definition, a general definition encompassing most Free software licenses

His main agenda is to educate business about open source software, to make a business case rather than a social one

Free vs. freeOpen Source and Free Software are very

similar (but not identical) and the definition can usually be interchanged.

Free software’s capital “F” is used to denote 2 meanings of free:

1. Free as in free beer2. Free as in freedom (the ability to use,

distribute and modify the software as you wish)

Common examples of Free SoftwareLinuxJavaMediaWiki (i.e. WikiPedia)ApacheAsteriskFreeBSDOpenOffice.orgMozilla FirefoxAudacity (audio editor)

Common LicensesGeneral Public License (GPL) v2 – most popular

license Examples using v2

Linux kernelThe GNU software suite (gcc etc.)MySQL databaseJavaAsterisk (PBX software)60+ % of the software on freshmeat and sourceforge

Common LicensesGeneral Public License (GPL) v3Newer, not as popular yet

OpenOffice.org v3+

BSD License – least restrictive licenseExamples

Free BSD Open BSD PostgreSQL database

Apache license – similar to BSD license• Examples• Apache Web server• Most popular Web server on the

Internet

Why use Free Software?Freedom

If you are a coder, you can modify the software any way you like to do anything you want

If you are a user, you can install the software on anything you like, as many times as you like (No CD keys or “activation”)

Free• Software is freely available at no cost

Why not use Free Software?No “throat to choke”

Free software no official corporate support, you are responsible for fixing it if it breaks or pay a 3rd party for support

You must share your code too–With GPL software, any modifications or

enhancements to GPL software that you distribute must also be licensed under the GPL and be made available to everyone. (This only applies if you distribute the code outside your organization)
