OSS: DefinitionOpen-source software (OSS) is computer softwarethat is available in source code form for which thesource code and certain other rights normallyreserved for copyright holders are provided undera software license that permits users to study,change, and improve the software.The license has to comply to the Open SourceDefinition given by Open Source Initiative (OSI).
Free Software??● Free Software Refers to the software that provides the following freedoms : ● The freedom to run the program, for any purpose (freedom 0). ● The freedom to study how the program works, and change it to make it do what you wish (freedom 1). ● The freedom to redistribute copies so you can help your neighbor (freedom 2). ● The freedom to distribute copies of your modified versions to others (freedom 3).
Commercial Open Source● Red Hat Enterprise Linux● Suse Enterprise Edition● OpenExchange Enterprise● Xtuple ERP● Landscape● Dim Dim● Star Office
Business Models● Support and Service Models (Ubuntu)● Free and Enterprise Versions (MySQL, Red Hat)● SaaS model (Dim Dim)● Products around Open Source (Amanda - MySQL, Ubuntu – Landscape )
SourceForge● SourceForge is a web- based source code repository. It acts as a centralized location for software developers to control and manage open source software development.
FreshMeat.net● Freshmeat is a website that allows computer users to keep track of the latest software releases and updates as well as write/read reviews and articles, send or receive comments to or from the author, and many other features.● Programmers register their projects and inform the site about updates; users browse for software and download and (sometimes) rate or comment on the software.● Software is categorized by field of application, license, development status, environment, intended audience, type of use, supported operating systems, and used programming and available natural languages.
EduForge.org● Open Source Learning Lab● Eduforge is a virtual collaborative learning and exploratory environment designed for the sharing of ideas, research outcomes and information about open source.● It is an open access environment allowing anyone with an interest in open source software to join the community. Eduforge also provides the Open Source Learning Lab to provide training for open source practitioners through a 100% online delivery model.
The Linux Documentation Project● http://tldp.org/● LDP is a loosely knit team of volunteers who provide documentation for many aspects of Linux. There are several forms of documentation: Guides, HOWTOs, man pages, and FAQs.
Copyleft● Common practice for using copyleft is to codify the copying terms for a work with a license.● Any such license typically gives each person possessing a copy of the work the same freedoms as the author, including (from the Free Software Definition): ● the freedom to use the work, ● the freedom to study the work, ● the freedom to copy and share the work with others, ● the freedom to modify the work, and the freedom to distribute modified and therefore derivative works.
Copyleft● Copyleft says that anyone who redistributes the software, with or without changes, must pass along the freedom to ruther copy and change it.● If they do not, they lose their rights.● As Stallman puts it, “Copyleft guarantees that every user has freedom, and ensures that somebody does not remove the freedom from free software.● “Proprietary software According to Free Software Foundation, developers use copyright to take away the users freedom; we use copyright to guarantee their freedom. Thats why we reverse the name, changing copyright into copyleft.”
GNU GPL● GNU General Public License● The strongest copyleft and most widely used free software license is the GNU Genral Public License, or GNU GPL for short.● Using the GNU GPL will require that all the released improved versions be free software. This means you can avoid the risk of having to compete with a proprietary modified version of your own work.● http://www.gnu.org/licenses/gpl-faq.html
