Open source software- A boon to programmers

Open source software is a software that is developed, tested and modified through public teamwork. It is shared with others to take the benefit of future technology. In simple language, the term “open source” is something people with coding knowledge can modify and share. This feature is available as its design is accessible for free on the internet.

Open source documents enjoy the principles of open exchange, rapid prototyping, transparency, collaborative participation, meritocracy and community-oriented development.

Difference between open source software and other types of software

Software has source code and only the person, team or organization who developed the code has the exclusive rights to maintain the code. In general terms, this type of software is termed as “proprietary” or “closed source” software. Whereas, open source software works on different methodology. The developer who developed this software share the code to others who would like to view the code for different reasons. The reason of the programmer other than developer to access the code is to copy, learn or sometime to develop something unique from an existing code.

The motive of the developer to share the open source software code with others is to enhance the features of software or to fix the bug in the code.

Why programmers prefer to use open source software?

Following are the reasons why programmers prefer open source software:

·         Control: Programmers prefer open source software because they have full access over the software internal coding, it means programmers can examine the code to ensure the code is not doing anything for which it is not programmed for and they have all the rights to change any part of the code which they don’t like.

·         Training: People other than programmers like open source software because it helps them to learn the coding. As the code of open source software is shared publicly, so students pursuing the IT course can learn how to make a better software.

·         Security: Some people like to use open source software because they find it more secure and stable than any proprietary software. As this is publicly accessible, so anyone can view and modify the code, if flaws traced that the developer might have missed.

·         Stability: Programmers use open source software for important and long term projects. Because the developer publicly distributes the source code, programmers trusting on the software for the critical tasks can be sure their technology on which they are working won’t disappear in case developer stop working further on the coding.

·         Reusability: Programmers use the open source code of the software to lessen their workload when they knew the same functionality is available for free. So, they just use the code for adding a particular functionality in their working software. This saves their time and efforts in coding.

Advantages of using open Source Software

·         Reliability

·         Stability

·         Auditability

·         Cost

·         Flexibility and Freedom

·         Support and Accountability
