What is FOSS?

FOSS (Free and Open Source Software) is asoftware licensing model that allows anyone theliberty to use, extend and distribute the software

as they see fit. Represents a spectrum of licenses.

FOSS is unique as well in that it producesinnovation quickly by the very concept of open,

cooperative, collaborative sharing anddevelopment.

Commercial software is much more restrictive.


9/63


FOSS vs. Commercial

Licensed with very specific rights associated withits use, modification, distribution and use that arenot commonly available to a user via commercialclosed software.

Software licenses of traditional commercialsoftware define specific permission, rights andrestrictions.

Licensee determines the license terms.

Much more restrictive that FOSS. Freedom, sharing, collaboration are not inherit

parts of this traditional closed model whichtypifies the traditional software industry.


10/63


What FOSS is NOT

Freeware

Shareware

Public Domain Software

Malware, spyware, adware, badwareetc. Community standards generalprohibit this.

RMS & the FSF

FSF Free Software Foundation

Founded in 1983 by RichardStallman with the goal of creating afree Unix like OS, GNU Project.

Consummate computer

scientist/hacker who createdEmacs, GNU Complier, GNUDebugger.

Spearhead the efforts of FreeSoftware movement.

Created several copyright license

such as the GNU/GPL which is themost popular FOSS licenses.


17/63


FSF

Patent reforms are also critical to RMS and theFSF.

Free as in Freedom. Price is not the issue.Uncompromising stance on free software andpatents.

Doesn't like the term Open Source.

Enter the Linus

Linus Torvalds in 1991 createsfirst Linux kernel.

Released in 1992 underGNU/GPL

Kernel + GNU Project (systemslibs/utils) = GNU/Linux

Now kernel project coordinatorand keeper of Linuxtrademark.

Neutral on Free Software andmore focused on quality.

Differs with RMS.

http://www.kernel.org/
http://www.kernel.org/http://www.kernel.org/


19/63


Early Days

Kernel licensed under GNU/GPL propelledinterest, innovation and ingenuity of FOSScommunity.

The Linux Kernel plus the systems utilitiesand libraries from the GNU project yieldedLinux in many forms.

Early distributions such as Debian &Slackware appeared in 93.

Evolution of GNU/Linux

Linux Evolutionary Time line


21/63


Perception & Ambiguity of Free

Free software inherently exists in thecontext of capitalism and free enterprise,not outside it.

Problem was the term free was nothelpful in selling software.

If its free what would you be buying?Ugh!

Who would champion such a cause?


22/63


And along came the OSI

OSI non-profit created in 1998by Bruce Perens & Eric Raymondto promote open source.

Open source was a repositioningof free software with a term thatwas to clear up the ambiguity

seen in the term free.

Attempt was to make freesoftware provide a more businessfriendly effort with less of thedeep idealogical slant.

Uphold and promotes OpenSource Definition.
