Software Gratis Around The World
Example of a modern free-software operating system running some representative applications. Shown are the desktop environment, the web browser, the text editor, the image editor, and the media player.Free software or libre software is distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of, not price: users—individually or in cooperation with —are free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program. Computer programs are deemed free if they give users (not just the developer) ultimate control over the software and, subsequently, over their devices.The right to study and modify a computer program entails that —the preferred format for making changes—be made available to users of that program. While this is often called 'access to source code' or 'public availability', the recommends against thinking in those terms, because it might give the impression that users have an obligation (as opposed to a right) to give non-users a copy of the program.Although the term 'free software' had already been used loosely in the past, is credited with tying it to the sense under discussion and starting the in 1983, when he launched the: a collaborative effort to create a freedom-respecting, and to revive the spirit of cooperation once prevalent among during the early days of computing. This describes the typical relationship between freeware and (FOSS): According to David Rosen from in 2010, open source / free software (orange) is most often gratis but not always.
Freeware (green) seldom expose their source code.Free software thus differs from:., such as, and or from. Users cannot study, change, and share their., which is a category of proprietary software that does not require payment for basic use.For software under the purview of to be free, it must carry a whereby the author grants users the aforementioned rights. Software that is not covered by copyright law, such as software in the, is free as long as the source code is in the public domain too, or otherwise available without restrictions.Proprietary software uses restrictive software licences or and usually does not provide users with the source code. Users are thus legally or technically prevented from the software, and this results on reliance on the publisher to provide updates, help, and support. (See also and ). Users often may not, modify, or redistribute proprietary software.
Beyond copyright law, contracts and lack of source code; there could be additional shenanigans keeping users from exercising freedom over a piece of software, such as and (more specifically, ).Free software can be a for-profit, commercial activity or not. Some free software is developed by volunteer while other is developed by corporations; or even by both. Naming and differences with Open Source.
Main article:Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term 'free software' rather than ' (a younger vision coined in 1998), because the goals and messaging are quite dissimilar. 'Open source' and its associated campaign mostly focus on the technicalities of the and marketing free software to businesses, while taking the ethical issue of user rights very lightly or even antagonistically. Stallman has also stated that considering the practical advantages of free software is like considering the practical advantages of not being handcuffed, in that it is not necessary for an individual to consider practical reasons in order to realize that being handcuffed is undesirable in itself.The FSF also notes that 'Open Source' has exactly one specific meaning in common English, namely that 'you can look at the source code.' It states that while the term 'Free Software' can lead to two different interpretations, at least one of them is consistent with the intended meaning unlike the term 'Open Source'. The loan adjective ' is often used to avoid the ambiguity of the word 'free' in, and the ambiguity with the older usage of 'free software' as public-domain software.
See.Definition and the Four Freedoms. Diagram of free and nonfree software, as defined by the Free Software Foundation. Left: free software, right: proprietary software, encircled:The first formal definition of free software was published by FSF in February 1986.
That definition, written by Richard Stallman, is still maintained today and states that software is free software if people who receive a copy of the software have the following four freedoms. Main article:There are thousands of free applications and many operating systems available on the Internet. Users can easily download and install those applications via a that comes included with most.The maintains a large database of free-software packages. Some of the best-known examples include the, the and Linux operating systems, the and; the relational database; the web server; and the mail transport agent. Other influential examples include the text editor; the raster drawing and image editor; the graphical-display system; the office suite; and the and typesetting systems. Free Software.
Founder of the (2002)From the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which was typically. Was commonly shared by individuals who used computers and by hardware manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, were formed to facilitate exchange of software. As software was often written in an interpreted language such as, the was distributed to use these programs. Software was also shared and distributed as printed source code in (like, etc) and books, like the bestseller.
By the early 1970s, the picture changed: software costs were dramatically increasing, a growing software industry was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software, and some customers able to better meet their own needs did not want the costs of 'free' software bundled with hardware product costs. In United States vs., filed January 17, 1969, the government charged that bundled software was. While some software might always be free, there would henceforth be a growing amount of software produced primarily for sale. In the 1970s and early 1980s, the began using technical measures (such as only distributing of ) to prevent from being able to study or adapt the software applications as they saw fit.
In 1980, law was extended to computer programs.In 1983, one of the original authors of the popular program and a longtime member of the community at the, announced the, the purpose of which was to produce a completely non-proprietary operating system, saying that he had become frustrated with the shift in climate surrounding the computer world and its users. In his initial declaration of the project and its purpose, he specifically cited as a motivation his opposition to being asked to agree to and restrictive licenses which prohibited the free sharing of potentially profitable in-development software, a prohibition directly contrary to the traditional. Software development for the began in January 1984, and the (FSF) was founded in October 1985.
He developed a free software definition and the concept of ', designed to ensure software freedom for all.Some non-software industries are beginning to use techniques similar to those used in free software development for their research and development process; scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under licenses (see the project, for instance). And the have also been largely influenced by the free software movement.1980s: Foundation of the GNU project In 1983, longtime member of the community at the, announced the GNU project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users. Software development for the GNU operating system began in January 1984, and the (FSF) was founded in October 1985.
An article outlining the project and its goals was published in March 1985 titled the. The manifesto included significant explanation of the GNU philosophy, and ' ideas.1990s: Release of the Linux kernel The, started by, was released as freely modifiable source code in 1991. The first licence was a proprietary software licence. However, with version 0.12 in February 1992, he the project under the.
Much like Unix, Torvalds' kernel attracted the attention of volunteer programmers.and (both derived from ) were released as free software when the lawsuit was settled out of court in 1993. From NetBSD in 1995. Also in 1995, The, commonly referred to as Apache, was released under the.Licensing.
A novel use of copyright law to ensure that works remain unrestricted, originates in the world of free software.All free-software licenses must grant users all the freedoms discussed above. However, unless the applications' licenses are compatible, combining programs by mixing source code or directly linking binaries is problematic, because of. Programs indirectly connected together may avoid this problem.The majority of free software falls under a small set of licenses. The most popular of these licenses are:. The.

The (MPL). TheThe Free Software Foundation and the Open Source Initiative both publish lists of licenses that they find to comply with their own definitions of free software and open-source software respectively:.The FSF list is not prescriptive: free-software licenses can exist that the FSF has not heard about, or considered important enough to write about.
So it's possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the in order to be officially recognized as open source software.
Free software, on the other hand, is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet the Free Software Definition cannot rightly be considered free software.Apart from these two organizations, the project is seen by some to provide useful advice on whether particular licenses comply with their. Debian doesn't publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That is summarized at the Debian web site.It is rare that a license announced as being in-compliance with the FSF guidelines does not also meet the, although the reverse is not necessarily true (for example, the is an OSI-approved license, but non-free according to FSF).There are different categories of free software. software: the copyright has expired, the work was not copyrighted (released without before 1988), or the author has released the software onto the public domain with a statement (in countries where this is possible).
Since public-domain software lacks copyright protection, it may be freely incorporated into any work, whether proprietary or free. The FSF recommends the public domain dedication for this purpose., also called BSD-style because they are applied to much of the software distributed with the operating systems: these licenses are also known as as they have no restrictions on distribution. The author retains copyright solely to disclaim warranty and require proper attribution of modified works, and permits redistribution and any modification, even closed-source ones. In this sense, a permissive license provides an incentive to create non-free software, by reducing the cost of developing restricted software. Since this is incompatible with the spirit of software freedom, many people consider permissive licenses to be less free than copyleft licenses. licenses, with the being the most prominent: the author retains copyright and permits redistribution under the restriction that all such redistribution is licensed under the same license. Additions and modifications by others must also be licensed under the same 'copyleft' license whenever they are distributed with part of the original licensed product.
This is also known as a, or reciprocal license. Due to the restriction on distribution not everyone considers this type of license to be free.Security and reliability. Although nearly all only affect, such as (shown here) is still provided for Linux and other Unix-based systems, so that users can detect that might infect Windows hosts.There is debate over the of free software in comparison to proprietary software, with a major issue being. A popular quantitative test in computer security is to use relative counting of known unpatched security flaws. Generally, users of this method advise avoiding products that lack fixes for known security flaws, at least until a fix is available.Free software advocates strongly believe that this methodology is biased by counting more vulnerabilities for the free software systems, since their source code is accessible and their community is more forthcoming about what problems exist, (This is called 'Security Through Disclosure' ) and proprietary software systems can have undisclosed societal drawbacks, such as disenfranchising less fortunate would-be users of free programs. As users can analyse and trace the source code, many more people with no commercial constraints can inspect the code and find bugs and loopholes than a corporation would find practicable.
According to Richard Stallman, user access to the source code makes deploying free software with undesirable hidden functionality far more difficult than for proprietary software.Some quantitative studies have been done on the subject. Binary blobs and other proprietary software In 2006, started the first campaign against the use of in. Blobs are usually freely distributable for hardware from vendors that do not reveal driver source code to users or developers. This restricts the users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have, they pose a security risk to any whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free.The issue of binary blobs in the and other device drivers motivated some developers in Ireland to launch, a Linux based distribution with all the binary blobs removed.
The project received support from the and stimulated the creation, headed by the, of the kernel. As of October 2012, is the most popular FSF endorsed Linux distribution ranked by Distrowatch (over 12 months). While is not endorsed by the FSF and does not use Linux-libre, it is also a popular distribution available without kernel blobs by default since 2011. Business model. See also:under any free-software licence is permissible, as is commercial use. This is true for licenses with or without.Since free software may be freely redistributed, it is generally available at little or no fee.

Free software business models are usually based on adding value such as customization, accompanying hardware, support, training, integration, or certification. Exceptions exist however, where the user is charged to obtain a copy of the free application itself.Fees are usually charged for distribution on compact discs and bootable USB drives, or for services of installing or maintaining the operation of free software. Development of large, commercially used free software is often funded by a combination of user donations, corporate contributions, and tax money. The project at the United States is an example of a federally funded free-software project.Proprietary software, on the other hand, tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for a fee.The Free Software Foundation encourages selling free software.
As the Foundation has written, 'distributing free software is an opportunity to raise funds for development. Don't waste it!' For example, the FSF's own recommended license (the ) states that 'you may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.'

Microsoft CEO stated in 2001 that 'open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source.' This misunderstanding is based on a requirement of licenses (like the GPL) that if one distributes modified versions of software, they must release the source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and free software is also a misunderstanding. There are several large companies, e.g.
And, which do substantial commercial business in the development of free software. Economical aspects and adoption. “We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable - one that would give us in-house control. So if we needed to patch, adjust, or adapt, we could.”Official statement of the, which manages the computer systems for the (ISS), regarding their May 2013 decision to migrate ISS computer systems from Windows to LinuxThe economic viability of free software has been recognized by large corporations such as,. Many companies whose core business is not in the IT sector choose free software for their Internet information and sales sites, due to the lower initial capital investment and ability to freely customize the application packages.
Most companies in the software business include free software in their commercial products if the licenses allow that.Free software is generally available at no cost and can result in permanently lower compared to. With free software, businesses can fit software to their specific needs by changing the software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage.
Such an agreement is made separately from the free software license.A report by estimates that adoption of free software has caused a drop in revenue to the industry by about $60 billion per year. In spite of this, argues that the term free software is too ambiguous and intimidating for the business community.
Raymond promotes the term as a friendlier alternative for the business and corporate world. See also. See GNU Project. Free Software Foundation. ^. Retrieved 26 March 2017.
