Why Open Source?
All Farm Hack documentation and written materials are open source, both hardware and software. (Some prefer the term "free software" to "open source software"). This means that you're free to use, modify, and redistribute them, as long as you open source your own contributions.
Why do we do things this way? By sharing our techniques and tools under open source licenses, we ensure that the development process is open, and that anyone can contribute. Open sourcing also ensures that nobody can take exclusive control of a project by using patents or copyrights to exclude others from using it.
This license also means that if you use these tools, you are obliged to share any improvements or modifications you make under the same open source license. Think of it as "giving something back" to everyone else who's helped to develop the technology.
About the licenses
By publishing your work on this website, you agree to license your work under the CC-BY-SA. Any work which you do not wish to license should be clearly marked as such.
The legal concept of the Public Domain as related to copyright is primarily within the United States, where it refers to yielding or giving up all copyright, irrevocably. This means that anyone can reuse, republish, or adapt the content, without asking permission or even attributing the authors. Works produced by the federal government of the US are supposed to be automatically released into the Public Domain. For outside the US, the Creative Commons Zero license, which attempts to be the equivalent of Public Domain, but internationally viable.
Creative Commons: "CC"
These licenses, which can be read about at the Creative Commons website, are easy-to read, thorough, and come in a few flavors, which can be mixed and matched. Farm Hack content is released under both Attribution and Share-Alike provisions, a combination typically referred to as "CC-BY-SA".
The ShareAlike provision requires that derivative works be released under the same license. This tends to encourage users to "give back" -- sharing what they've done, re-contributing their improvements, additions, and changes back to the community. This means that any time you use, adapt, or republish content bearing this license, you must use the same license for your publication.
