It’s amazing how our entire world has become digital. A multitude of devices and gadgets surrounds us, and we can’t imagine our lives without them now. One among the many that have engulfed us in its usefulness is open source software.
To be honest, it literally feels like open source software is an anomaly in this tech-dominated world. The thought that a community of developers are so comfortable working on a single piece of software for years without money is absolutely mindblowing.
As we have done a thorough analysis of open-source software in our previous article, it’s time to get into the depth of this realm.
For your benefit, we’ve decided to enlist the open source software examples of 2021. But before that let’s discuss why you should use open-source software?
Why Should You Use OSS?
The answer is simple; it provides you a platform to contribute and learn from others. There are countless benefits of open-source software that you should consider to make the most of it. That’s why the list of open source software examples of 2021 is extensive for you to benefit from.
Here are some of the benefits that OSS provide us:-
Open-source software is very cost-effective as a majority of this is freely distributed. The source code can be altered, which frees the organization from what is commonly known as “vendor lock-in.”
It is a term that signifies that the company has to be dependent on a single vendor for the regular updates of the products.
If you purchase a closed proprietary software like Microsoft’s Windows and office, you are bound to accept the predefined terms and conditions that restrict the ways developers utilize a given product.
On the contrary, everything is flexible with open-source software. Anybody can modify it according to their specific needs. A great example of this is Drupal; it has been adopted by universities, cities, towns, and even the White House.
Embraces Strong Values
Open-source software embrace values of:-
All these values are promoted for the mutual benefit of the platform as well as for the users.
This sense of intense commitment towards the community encourages the programmers to develop new advanced features, due to which OSS projects are often considered to be on the cutting edge of technology.
Continuous improvements by various developers make this happen.
Linus Torvalds, the creator of Linux, said, “Given enough eyeballs, all bugs are shallow.”
This means that the more people look at a code and test it, the greater the probability of finding a problem that may go unnoticed.
Due to crowdsourcing, there is constant peer review by the developers; they are constantly reviewing the code, closing gaps in security, and trying out new improvements.
So, In the case of open-source software, bugs are detected before they can cause any serious harm and are solved, unlike closed software, where a detected bug may take months to repair.
Contributions by Community
A community of experts is behind the constant development of open-source software. They give utmost importance to freedom and want the software to become efficient enough to be utilized by anyone with access.
Therefore, various documentation, email lists, forums, wikis, newsgroups, or even live chats are provided for every popular open-source project.
Check out more advantages of using open source software here.
