The free software movement was launched in 1983. In 1998, a group of individuals advocated that the term free software be replaced by open source software (OSS) as an expression which is less ambiguous and more comfortable for the corporate world. Software developers may want to publish their software with an open source license, so that anybody may also develop the same software or understand how it works. Open source software generally allows anyone to make a new version of the software, port it to new operating systems and processor architectures, share it with others or market it.
The Open Source Definition, notably, presents an open source philosophy, and further defines a boundary on the usage, modification and redistribution of open source software. Software licenses grant rights to users which would otherwise be prohibited by copyright. These include rights on usage, modification and redistribution. Several open source software licenses have qualified within the boundary of the Open Source Definition. The most prominent example is the popular GNU General Public License (GPL). While open source presents a way to broadly make the sources of a product publicly accessible, the open source licenses allow the authors to fine tune such access.
The "open source" label came out of a strategy session held in Palo Alto in reaction to Netscape's January 1998 announcement of a source code release for Navigator (as Mozilla). A group of individuals at the session included Todd Anderson, Larry Augustin, John Hall, Sam Ockman, Christine Peterson and Eric S. Raymond. They used the opportunity before the release of Navigator's source code to clarify a potential confusion caused by the ambiguity of the word "free" in English. The 'open source' movement is generally thought to have begun with this strategy session. Many people, nevertheless, claimed that the birth of the Internet, since 1969, started the open source movement, while others do not distinguish between open source and free software movements.
The Free Software Foundation (FSF), started in 1985, intended the word 'free' to mean "free as in free speech" and not "free as in free beer" with emphasis on the positive freedom to distribute rather than a negative freedom from cost. Since a great deal of free software already was (and still is) free of charge, such free software became associated with zero cost, which seemed anti-commercial.
The Open Source Initiative (OSI) was formed in February 1998 by Eric S. Raymond and Bruce Perens. With at least 20 years of evidence from case histories of closed development versus open development already provided by the Internet, the OSI presented the 'open source' case to commercial businesses, like Netscape. The OSI hoped that the usage of the label "open source," a term suggested by Peterson of the Foresight Institute at the strategy session, would eliminate ambiguity, particularly for individuals who perceive "free software" as anti-commercial. They sought to bring a higher profile to the practical benefits of freely available source code, and they wanted to bring major software businesses and other high-tech industries into open source. Perens attempted to register "open source" as a service mark for the OSI, but that attempt was impractical by trademark standards. Meanwhile, thanks to the presentation of Raymond's paper to the upper management at Netscape (Raymond only discovered when he read the Press Release
, and was called by Netscape CEO Jim Barksdale's PA later in the day), Netscape released its Navigator source code as open source, with favorable results. (WIKIPEDIA)
aku rase ramai yg tau ape itu open source bukan? kalo nak lebih lanjut korang bole pegi kt wiki, taip je open source. jgn malas nak baca. open source software ialah software yg legal di download, di ubahsuai codenya sesuka hati. dan yg paling penting, ia FREE!. byk alternatif lain yg ade dlm open source ini yg bagi aku efektif, tak besar, dan tak rugi pun kalo pakai. kalo taknak pakai IE, kita ade Firefox, Takde zip or rar software, kite leh guna Peazip, kalo takde Microsoft Office kite ade Open Office, Takde Windows kite ade Linux dan mcm2 lagi lah. so bg yg baru nak mencuba guna bermacam2 open source software, korang bole la try oke?
*Viva La OSS!!
