  3. A history of Linux The history of Linux is one of the most well-known histories within the world of free software. In 1991, a Finish student - Linux Torvalds At that time, there was a kernel in the operating system called Minix, designed for academic purposes and for use in university courses on operating systems; this is still used today. Andrew Tanenbaum, one of the most prestigious professors at the university, was the leader of the team working on the development of Minix, based on traditional Unix systems DEPT OF CIT; CSE-IBM; UNIT-3

  5. Minix Minix had a free distribution license and could be used for academic purposes, but it had the big disadvantage that people that did not work or study in the University of Amsterdam could not add improvements to it. DEPT OF CIT; CSE-IBM; UNIT-3

  6. UNIT-3 History of LINUX In mid-1991, Linus, then an anonymous Finnish student, sent a message to the Minix newsgroup announcing that he was going to start work on an operating system kernel based on Minix, from scratch, rewriting code. Version 0.02, which dates from October 1991, despite being very limited, could already execute bash terminals and the GCC compiler. in March 1994, Linux 1.0 was finally born. By this time, Linux was being published under the terms of the GPL license; according to Torvalds himself, this was one of the best decisions he ever made, as it was extremely helpful in distributing and popularizing his kernel. DEPT OF CIT; CSE-IBM; UNIT-3

  7. LINUX'S way of working The way Torvalds worked was not very common at that time. The development was mainly based on a mailing list9. The mailing list was a place where people not only argued, but where developments also took place. Linus preferred to have the code sent in the body of the message so that he and others could comment on the code. In any case, although many people would provide their opinions and send corrections or new functions, the last word would always go to LinusTorvalds, who would decide on what code would be incorporated into Linux.

  13. FreeBSD (Berkely Software Distribution)Developed by University of Berkely DEPT OF CIT; CSE-IBM; UNIT-3

  14. FreeBSD there are other types of free software operating systems, apart from the popular GNU/ Linux. A family of these are the "inheritors" of the distributions of Berkeley University, in California (US): BSD type systems. FreeBSD, which was created in early 1993, when Bill Jolitz stopped publishing the unofficial updates to 386BSD. With the assistance of the company Walnut Creek CDROM, which subsequently changed its name to BSDi, a group of volunteers decided to carry on creating this free operating system. DEPT OF CIT; CSE-IBM; UNIT-3

  15. History of FreeBSD Version 1.0 appeared towards the end of 1993 and was based on 4.3BSD Net/2 and 386BSD. 4.3BSD Net/2 had code that was created in the seventies, when Unix was being developed by AT&T, which, as it turned out, involved a series of legal problems that were not resolved until 1995, when FreeBSD 2.0 was published without the original code developed by AT&T DEPT OF CIT; CSE-IBM; UNIT-3

  16. Development in FreeBSD FreeBSD distributes its software in two forms: on the one hand, the ports, a system that downloads the source codes, compiles them and installs the application in the local computer, 2. and on the other, the packages, which are simply the source codes of the precompiled ports and, therefore, in binary DEPT OF CIT; CSE-IBM; UNIT-3

  17. Decision-making process in FreeBSD The board of directors of FreeBSD, famously called the core team, is in charge of defining the direction of the project and ensuring that the objectives are met, as well as mediating in cases in which there are conflicts between committers. DEPT OF CIT; CSE-IBM; UNIT-3

  18. Current status of FreeBSD • the number of web servers that run FreeBSD is approximately two million. • One of the star features of FreeBSD is what is known as the jails. The jails • minimize the damage that might be caused by an attack on basic network • services, • One of the most interesting aspects of FreeBSD is that the figures are very similar to the ones of in KDE and GNOME: the size of the software easily exceeds five million lines of code, the number of files is approximately 250,000 and the total number of commits is approximately two million.

  21. KDE DEPT OF CIT; CSE-IBM; UNIT-3

  22. History of KDE Unix followers were quick to notice the outstanding success of Windows 95 The KDE K Desktop Environment project was born from this effort in 1996; it was designed by Matthias Ettrich (creator of LyX, an editing program in the TeX typeset) DEPT OF CIT; CSE-IBM; UNIT-3

  23. Development of KDE KDE is one of the few free software projects that generally follows a new version launch schedule The companies that participate in the KDE League are mainly distribution designers (SuSE, now part of Novell, Mandriva, TurboLinux, Lindows and Hancom, a Korean free software distribution), DEPT OF CIT; CSE-IBM; UNIT-3

  24. Current status of KDE The latest KDE version is, as at early 2007, version 3.5.6 and the fourth generation, KDE 4 DEPT OF CIT; CSE-IBM; UNIT-3

  27. GNOME GNU Network Object Model Environment DEPT OF CIT; CSE-IBM; UNIT-3

  28. GNOME The main objective of the GNOME project is to create a desktop system for the end user that is complete, free and easy to use. GNOME-GNU Network Object Model Environment From its name, we see that GNOME is part of the GNU project. Currently DEPT OF CIT; CSE-IBM; UNIT-3

  29. History of GNOME Whilst the freedom of KDE was still being argued about, in the summer of 1997, as fate would have it, Miguel de Icaza and Nat Friedman met at Redmond during some workshops organised by Microsoft. It is probable that this meeting caused a radical turnaround in both, resulting in the creation of GNOME by Miguel de Icaza when he returned to Mexico (along with Federico Mena Quintero) and his admiration for distributed object technologies. De Icaza and Mena decided to create an environment that would be an alternative to KDE, as they understood that a reimplementation of a proprietary library would have been a task destined to failure. And thus GNOME was born. DEPT OF CIT; CSE-IBM; UNIT-3

  30. The GNOME Foundation • In general terms, the GNOME Foundation is divided into two large committees: • a managing committee and • an advising committee. DEPT OF CIT; CSE-IBM; UNIT-3

  35. Apache The HTTP Apache server is one of the star applications of the world of free software, as it is the web server that is most widely used, DEPT OF CIT; CSE-IBM; UNIT-3

  36. History of Apache In March 1989, Tim Berners Lee, an English scientist that worked in the CERN (Switzerland) proposed a new method for managing the huge amount of information from the CERN projects. The method would be a network of hyperlinked documents the WWW was born. The real history of Apache began when Rob Mc Cool left the NCSA in March 1995. Apache 0.2 would be born on 18th March 1995, based on the NCSA HTTPd 1.3 server, DEPT OF CIT; CSE-IBM; UNIT-3

  37. Development of Apache The HTTP Apache server is the main project among the many that the Apache Software Foundation manages The development of the HTTP Apache server is based on the work of a small group of developers called the Apache Group. DEPT OF CIT; CSE-IBM; UNIT-3

  40. Mozilla DEPT OF CIT; CSE-IBM; UNIT-3

  41. Mozilla set of integrated applications for Internet, that are free and multiplatform, and the most notable products are the Mozilla Firefox web browser and the Mozilla Thunderbird email and news client. DEPT OF CIT; CSE-IBM; UNIT-3

  42. Mozilla’s Principles • Mozilla's products are based on three basic principles: • they must be free software, • respect the standards • and be portable to other platforms. DEPT OF CIT; CSE-IBM; UNIT-3

  43. History of Mozilla Around 1997, Netscape's market share had dropped sharply due to the spread of Microsoft Explorer; On 15th July 2003, Netscape Inc. (now the property of America On Line) announced that it was no longer going to develop the Netscape browser and, therefore, was no longer going to actively take care of the Mozilla project. As a kind of "redundancy settlement" Netscape approved the creation of the Mozilla Foundation, which it supported with a contribution of two million dollars. DEPT OF CIT; CSE-IBM; UNIT-3

  44. Mozilla Mozilla project hosts various independent applications, the most notable of which include Mozilla Firefox (web browser), which is undoubtedly the most well-known, Mozilla Thunderbird (email and news client), Mozilla Sunbird (calendar), Mozilla Nvu (HTML editor), Camino (web browser designed for Mac OS X) and Bugzilla (web-based bug-tracker tool).
