25 Examples of free software

The free software It comprises the set of computer programming that can be used for any purpose, which especially includes adapting them to the individual needs of users, as well as the possibility of redistributing and eventually improving them. For instance: Ares, Mozilla Firefox, Moodle.

The idea of ​​free software is relatively new and it is very interesting, because it brings to light a subject in permanent debate, which is the social value of a product fruit of the intellectual capacity of one or more people, added to other resources.

In a certain way, computing thus joins a set of disciplines (such as biotechnology or genetics) in which the transfer to the community of what is generated becomes a delicate social and economic issue.

It is important to note that the software freedom It does not have to do with gratuitousness, nor with free access, but with a rather philosophical question, which conceives the user as a fundamental protagonist of what happens on the Internet and its evolution, assuming that software always involves knowledge that should not be prohibited to any of its potential users.

Advantages of free software

The totally opposite position to that of free software is that of proprietary software, that is, those developments on which rights are retained, with the restriction for the user to use it ‘as is’.

In practice, the central issue of free software is that this type of software allows the access to source code, and thanks to this it is that it offers freedom and possibility to modify it, study it and adapt it to the new needs that may appear. It is clear, then, that free software that is free but does not offer the source code is not considered free software.

It is to be expected that with the possibility of accessing the source code, a feedback correction dynamics by the user himself, without the need to be waiting for the official ‘new version’ of a company, as is the case with many other programs. This is the big bet made by the idea of ​​free software: the technical and economic advantages of a progress that is not powered only by a few heads within a corporation, but by the whole of society.

Many people linked to the world of programming have become partisans and sometimes even ‘militants‘of free software. From this point of view, it is understood that this type of program is the only one that fully respects the freedom of the user, and that the usual terms in the Copyright structures that support the type of proprietary software mean a certain deprivation of the users’ rights, obviously, in protection of the expected return on investments that are often millionaire.

This is why the free software movement created a legal mechanism known as ‘Copyleft’ license, in which they provide the way in which free software can be distributed. In this way, before accepting the ‘terms and conditions’, the user is warned of it. Many countries have already begun to legislate on the use and distribution of free software.
