What are the features of open source software?

Developing software using an open-source model is becoming increasingly popular. The main advantages that open-source software has over proprietary (closed-source) software are:

* Lower development cost. Individuals and smaller companies may aid in developing the software, reducing the number of programmers you have to pay yourself. * Bug detection and correction. With more people viewing your code from more diverse backgrounds, bugs will be found and fixed faster. This is often referred to as "Linus' Law": 'Given enough eyeballs, all bugs are shallow." * Reuse of code and shorter development time. Code from an older or different project can be incorporated into your new project, reducing the time it takes to create and develop it. * More independence. With a closed source project, you will have great problems if the developer goes out of business and you need your software updated or fixed. With the code open, any company can step in to fill the void. There may be some disadvantages to open-source software from a development perspective, though rarely any from the end-user perspective. The main problems are:

* Disclosure of trade secrets. Having the code for a program available implies revealing how it works. This includes disclosure of algorithms and how a device with a unique design might function. Revealing this information to others may cause duplication and loss of financial advantage. * Loss of revenue through traditional sales. If the source is available, then it is unlikely that consumers will pay a large amount for a CD or license. Revenue must instead be garnered through support agreements and OEM customization.
