4. OSS: Definition
Open-source software (OSS) is computer software
that is available in source code form for which the
source code and certain other rights normally
reserved for copyright holders are provided under a
software license that permits users to study, change,
and improve the software.
The license has to comply to the Open Source
Definition given by Open Source Initiative (OSI).
5. Definition by OSI
The Criteria for Open Source is as follows :
1. Free Redistribution
2. Source Code
3. Derived Works
4. Integrity of The Author's Source Code
5. No Discrimination Against Persons or Groups
6. No Discrimination Against Fields of Endeavor
7. Distribution of License
8. License Must Not Be Specific to a Product
9. License Must Not Restrict Other Software
10. License Must Be Technology-Neutral
6. Free Software
âFree Software Refers to the software that provides the following
freedoms :
âThe freedom to run the program, for any purpose (freedom 0).
âThe freedom to study how the program works, and change it to
make it do what you wish (freedom 1). Access to the source code
is a precondition for this.
âThe freedom to redistribute copies so you can help your neighbor
(freedom 2).
âThe freedom to distribute copies of your modified versions to
others (freedom 3). By doing this you can give the whole
community a chance to benefit from your changes. Access to the
source code is a precondition for this.
7. Free Software & OSS
âFree Software - Free as in free speech, not free
Beer.
âFreedom to ? - Share , Study , Modify
âAccording to Stallman - Few Licenses in Open
Source Restrict users in âdevelopment of
softwareâ
âOpen Source Considers only their underlying
criteria for their compliance, whereas free
software considers whether a device would let
you run the program or not.
8. Community Driven Software
âCathedral and Bazaar
âCathedral â Propritory Software â Microsoft ,
Apple , Oracle . Finely Developed in Isolation
âBazaar Model â Open Source, Free Software.
Many People, Different Perspectives, Common
Goal.
âPeople around the globe collaborate .
âBound by common goal , rules, policies.
âDifferent Perspectives
9. Why Should We Use It?
âMore Secure and Devoid of Viruses
âBetter Stability
âAvailability of wide range of development tools
âUpdated and Supported
âNo Piracy
âAll Drivers Available
âBugs Get Fixed Actively
âChage according to your will
âUse it in your local language
10. Commercial Open Source
âRed Hat Enterprise Linux
âSuse Enterprise Edition

11. Business Models
âSupport and Service Models (Ubuntu)
âFree and Enterprise Versions (MySQL, Red
Hat)
âSaaS model (Dim Dim)
âProducts around Open Source (Amanda -
MySQL, Ubuntu â Landscape )
12. Where to meet people?
âLinux User Groups â LUGs are local area
groups.
âFSF Chapters statewise
âLocal Groups Like Twincling in AP
âTech Specific groups, like Python User
Groups, Ruby User Groups, Lua User
