Creative Commons 4.0I recently read the Creative Commons announcement, CC’s Next Generation Licenses — Welcome Version 4.0!. This made me think more about licensing in general, as it has been a topic receiving increased attention recently in Open Source/Tech communities. I think it's a very important subject that anyone involved in Open Source should have at least some knowledge about.

Incorrectly or unlicensed software (or any other digital resource for that matter) can become a serious barrier to people attempting to reuse published works. I received my first exposure to the this when I was contributing to the Ubuntu project.

Since then I've become quite a proponent of making sure resources are properly licensed.

I was thrilled when GitHub made it a priority to encourage and facilitate hosted projects having conspicuous and unambiguous licensing. They even made a site,, to guide users through the process.

You can imagine I was quite surprised when I realized I never put a proper copyright/usage notice on the blog. That said, as of now this blog is officially licensed under the terms of the Creative Commons BY-SA 4.0 license. That means:
