Archimedes - "The Open CAD" - (aka Arquimedes) is a computer-aided design (CAD) program being developed with direct input from architects and architecture firms. With this design philosophy, the developers hope to create software better suited for architecture than the currently widely used AutoCAD, and other available CAD software. The program is free software released under the GNU General Public License.
It is a queue-theoretic event-based simulator written in Python. It is a process-based, object-oriented discrete-event simulation language.
It is a 3D modeling software written in Python and C++ that can make animations and games. It can be used for modeling, UV unwrapping, texturing, rigging, water simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications, including games.
Pencil is a 2D graphical animation software that runs on Mac, Windows, Linux and BSD. Pencil uses a unique bitmap/vector drawing interface to produce simple 2D graphics as well as animation. Pencil is written in C++ and is Qt-based. The application license is GNU General Public License.
SWFTools is a suite of software tools to create and manipulate SWF files. SWF is the file format used by Adobe Flash (formerly Macromedia Flash) animation software. SWFTools runs on Windows, Mac OS X, AmigaOS, Linux and several other Unix-like systems. It is distributed under the terms of the GNU General Public License and is thus free software.
Clam AntiVirus (ClamAV) is a free, cross-platform antivirus software tool-kit capable of detecting many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner. The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, Mac OS X, OpenVMS, OSF and Solaris. At one time it had a native version available for Windows, but that project has been ended. Both ClamAV and its updates are made available free of charge.
VLC media player is an open source, free software media player written by the VideoLAN project. VLC is a portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as DVDs, VCDs, and various streaming protocols. It is able to stream over networks and to transcode multimedia files and save them into various formats.
Media Player Classic (MPC) is a compact media player for Microsoft Windows. The application mimics the look and feel of the old, light-weight Windows Media Player 6.4 but integrates most options and features found in modern media players. It and its heirs are standard media players in the K-Lite Codec Pack and the Combined Community Codec Pack.
OpenOffice.org (OO.o or OOo), commonly known as OpenOffice, is an office application suite available for a number of different computer operating systems. It is distributed as free software and written using the gtk toolkit. It supports the ISO/IEC standard OpenDocument Format (ODF) for data interchange as its default file format, as well as Microsoft Office formats among others.
KOffice is a cross-platform office suite for the K Desktop Environment (KDE). All its components are released under free software/open source licenses and use OpenDocument as their native file format when possible.
Go-oo (previously called ooo-build) is a concentrated set of patches for the cross-platform OpenOffice.org office suite. Go-oo is also one of OpenOffice.org variants created from these patches. It has better support for Office Open XML file formats than the official OpenOffice.org releases produced by Sun Microsystems, and other enhancements that have either not yet been accepted into the upstream Sun version, or will not be because of business or political reasons.
Richard Stallman to satisfy the need for and to give the benefit of "software freedom" to computer users. The Free Software Foundation was founded in 1985 to provide the organizational structure which Stallman correctly foresaw would be necessary to advance his Free Software ideas.
The Mozilla Public License (MPL) is a free and open source software license. Version 1.0 was developed by Mitchell Baker when she worked as a lawyer at Netscape Communications Corporation and version 1.1 at the Mozilla Foundation.

The GNU General Public License (GNU GPL or simply GPL) is a widely used free software license, originally written by Richard Stallman for the GNU project.
The Apache License (Apache Software License previous to version 2.0) is a free-software license authored by the Apache Software Foundation (ASF). The Apache License (versions 1.0, 1.1, and 2.0) requires preservation of the copyright notice and disclaimer, but it is not a copyleft license — it allows use of the source code for the development of proprietary software as well as free and open source software.Like any free-software license, the Apache License allows the user of the software the freedom to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software.
The Apache License does not require modified versions of the software to be distributed using the same license nor even that it be distributed as free/open-source software. The Apache license only requires that a notice is kept informing recipients that Apache licensed code has been used. Thus, in contrast to copyleft licenses, recipients of modified versions of Apache licensed code do not necessarily also get the above freedoms. Or considering the situation from the Apache licensees perspective, they receive the freedom to use the code in any way they want, including using it in closed source products (cf Paragraph 4).
Two files that must be put at the top directory of redistributed software packages:
In every licensed file, any original copyright or patent notices in redistributed code must be preserved, and in every licensed file changed a notification must be added stating that changes have been made to that file.
The Apache Software Foundation and the Free Software Foundation (FSF) agree that the Apache License 2.0 is a free software licence, compatible with version 3 of the GNU General Public License (GPL). [5]
However, the Free Software Foundation considers all versions of the Apache License (as of 2007) to be incompatible with the previous GPL versions 1 and 2.
Open source software (OSS) is defined as computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that meets the Open Source Definition or that is in the public domain. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified forms. It is very often developed in a public, collaborative manner. Open source software is the most prominent example of open source development and often compared to user-generated content. The term open source software originated as part of a marketing campaign for free software. A report by Standish Group states that adoption of open source software models has resulted in savings of about $60 billion per year to consumers.
