Here is his list of  open source projects you could work on:

-      X.org develops the X window system software, a framework for building GUI environments, and is one of the oldest open source software projects out there. A great way for anyone to get started is by applying for the project?s mentorship program, Endless Vacation of Code.

-       LibreOffice is an open source alternative to Microsoft Windows software. ?They have a handy "tasks for newcomers list," says Greg KH.

-       GNOME is a popular Linux desktop environment. The project is looking for contributors with many different skill types, not just developers.

-       KDE develops workspace applications and provides an application development platform. ?They can always use the help, especially for the core bits,? says Greg KH.
