The open source contributions in any Organization makes you feel as a developer, a matured developer. I recently contributed to three open source projects:
While going through the code base of a project, one gets to know about the different coding styles. One also gets to know about the better way of implementation of his earlier projects.
Currently, I am focusing on Mozilla kitherder and Mozilla fjord project. These are the biggest projects that I have done in my life. Working on such a big project lets you to introduce yourself with other Developers.
I would like to help the new students who want to contribute to Open Source projects.
You can start contribution using the website http://openhatch.org . This website is the best one for starting open source contributions.
I have heard from many students that open source is something very big thing and they are not able to do anything in this field. So, I would like to inform all of you guys that its all matter of practice and hard work. The more you will explore the Github , Openhatch and the more you will learn form there. There is nothing that you can get without hard work. There is no shortcut to hard work.
Stay hungry Stay foolish.
