I have some code of which I don't care that much about. That what I host online, has no license and as such should be in the public domain.
Some projects contain files with:
GNU Lesser General Public License (version 2.1).
I understand that projects containing files with such licence must have all source code available to the public (which I have).
Must all source files in the same projects therefor also be provided with a GPL license or can I just keep my source codes licence-less as they are now.
