This is a list of free and open-source software packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.
 For more information about the philosophical background for open-source software, see free software movement and Open Source Initiative.
 However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa.
 A small fraction of the software that meets either definition is listed here.
Neil Modular Tracker is a Free Software project to create a functional Jeskola Buzz clone for Linux, based on an earlier, currently unmaintained program called "Aldrin".
 Maintained by Vytautas Jančauskas, it has ongoing activity as of 2011.
 The name is a wordplay on Buzz Aldrin and Neil Armstrong.
Jeskola Buzz is a freeware modular software music studio environment designed to run on Microsoft Windows using MFC.
 It is centered on a modular plugin-based machine view and a multiple pattern sequencer tracker.
Buzz Aldrin (born Edwin Eugene Aldrin Jr.; January 20, 1930) is an American engineer and former astronaut.
 As the Lunar Module Pilot on Apollo 11, he was one of the first two humans to land on the Moon, and the second person to walk on it.
 He set foot on the Moon at 03:15:16 on July 21, 1969 (UTC), following mission commander Neil Armstrong.
 He is a former U.S. Air Force officer with the Command Pilot rating.
 He also went into orbit on the Gemini 12 mission, finally achieving the goals for EVA (space-walk work) that paved the way to the Moon and success for the Gemini program; he spent over five hours on EVA on that mission.
Jonas Öberg (born 22 November 1977 in Sweden) is a free and open source software activist, describing himself as an instigator in the world of free, having worked with the Free Software Foundation Europe, GNU Project, FSCONS, Creative Commons and the Shuttleworth Foundation.
 He started to develop software in 1991 and installed his first GNU/Linux operating system in 1993 after which he eventually joined as a webmaster for the GNU Project.
 In the late 1990s, he spent some time at the MIT AI Labs where he met with Richard Stallman and others from the Free Software Foundation, joining them for The Bazaar conference in New York.
 Since 2002, he has been on the award committee for the Free Software Foundation's Free Software Awards.
Buzztrax is a free software project to create a clone of the Buzz music composer.
 The driving motivation is to preserve the playability of the compositions made with Buzz.
 Songs are made by adding virtual sound generators and effects, connecting them, recording short musical phrases and arranging them in the sequencer.
 For distribution, songs can be exported to common audio formats such as OGG, MP3, WAV and many others.
Apollo 11 was the spaceflight that landed the first two humans on the Moon.
 Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module "Eagle" on July 20, 1969, at 20:18 UTC.
 Armstrong became the first to step onto the lunar surface six hours after landing on July 21 at 02:56:15 UTC; Aldrin joined him about 20 minutes later.
 They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 lb of lunar material to bring back to Earth.
 Michael Collins piloted the command module "Columbia" alone in lunar orbit while they were on the Moon's surface.
 Armstrong and Aldrin spent just under a day on the lunar surface before rejoining "Columbia" in lunar orbit.
Fernanda "nanda" Giroleti Weiden is a system administrator and a former council member of Free Software Foundation Latin America (FSFLA), and she was a participant in Debian Women.
 She is an organizer of the Fórum Internacional Software Livre (FISL) and one of the founders of Projeto Software Livre Mulheres (Women in Free Software Project) in Brazil.
 She was elected the vice president of Free Software Foundation Europe (FSFE) in June 2009.
The origins of the Free software community in Thiruvananthapuram can be traced back to the group of TeX users around the University of Kerala in early 1980s.
 The community then later named themselves Thiruvananthapuram LUG (Indian Linux Users Group), GNU/Linux Users Group, Thiruvananthapuram and then ultimately Free Software Users Group, Thiruvananthapuram.
 The community has worked with the government in helping with key Free software initiatives in the government and also in promoting and supporting Free software among the general public.
 The community has also been instrumental in creating an IT policy favorable to Free software in the state of Kerala.
First on the Moon: A Voyage with Neil Armstrong, Michael Collins and Edwin E. Aldrin, Jr. (ISBN  ) is a book by the crew of the Apollo 11 Moon landing (Neil Armstrong, Michael Collins, Buzz Aldrin) in collaboration with Gene Farmer and Dora Jane Hamblin, first published in 1970.
