Open Source


The term Open Source, translated as "open source", refers to a type of software whose source code is accessible and available to the public. This allows anyone to view, modify, and distribute such software as permitted by their licenses.

History and Philosophy of Open Source

The idea of open source has been around since the early days of computing, when sharing software was a common practice. However, it wasn't until the 90s that the term "open source" was coined and the philosophy of open source software was formally established.

Richard Stallman, the founder of the GNU Project, is a central figure in the history of open source. Although the term "open source" was not adopted by Stallman, his philosophy of "free software" aligns with many of the same principles.

The philosophy of open source is based on the values of transparency, collaboration and freedom. It emphasizes that software should be freely accessible and modifiable, enabling collaboration and improvement of software by a global community of developers.

How Open Source Works

The open source development model is based on the idea that the source code of a software should be accessible to everyone. This allows any developer to view the code, learn from it, modify it, or improve the software. When an improvement is made, it is often shared with the community, allowing others to benefit from it as well.

In addition, open source software is generally free, although some companies and open source projects have business models that allow them to generate revenue.

Open Source Classification

Open source software is categorized according to the type of license it has. Each license provides a different set of permissions for users and developers. Here are some of the most common open source licenses:

  • MIT License: The MIT License is one of the most permissive open source licenses. It allows users to do virtually anything with the software, as long as a copy of the license is included and copyright is acknowledged.
  • GPL License: The GNU General Public License, or GPL, is a copyleft license. This means that any software derived from the original software must be kept as open source software. The GPL is the preferred license for projects that want to ensure the continuity of open source.
  • LGPL License: The GNU Lesser General Public License, or LGPL, is a more permissive version of the GPL. Allows software to link to non-GPL programs. This license is common in software libraries.
  • BSD License: The Berkeley Software Distribution (BSD) license is another permissive open source license. It is similar to the MIT license, but has an additional clause prohibiting the use of contributors' names to the software for the promotion of derivative products without specific permission.
  • MPL License: The Mozilla Public License, or MPL, is an open source license that sits somewhere between permissive and copyleft licenses. It allows the combination of MPL code with non-MPL code, but any changes to the MPL code must remain under the MPL.

Open source ratings are based on how the code is shared and allowed to be used. This system allows developers to choose the model that best suits their needs and goals, and at the same time contributes to transparency and collaboration in the software development community.

Advantages of Open Source

Open source has numerous advantages:

  • Accessibility: Anyone can access the source code, allowing you to learn from it or modify it as needed.
  • Collaboration: The open nature of code allows developers around the world to collaborate and improve software.
  • Transparency: By having access to the source code, the security and quality of the code can be verified.
  • Independence: With open source software, you don't rely on a single vendor, reducing the risk of issues like obsolescence.

Disadvantages of Open Source

Despite its advantages, open source also has disadvantages:

  • Support: While the open source community can be helpful, dedicated support is not always available.
  • Variable quality: The quality of open source software can vary, as anyone can contribute to the code.
  • Security risks: While transparency can improve security, it can also allow malicious actors to find and exploit vulnerabilities.

Impact of Open Source on Society and Technology

Open source has had a significant impact on the world of technology. Many of the most popular and used software today are open source, including the Linux operating system, the Apache web server, and the MySQL database management system.

In addition, open source has influenced the way software is developed and distributed, promoting collaboration, transparency, and freedom.
