What I have to do is blog about my own code. I already use github for my experiments and publish the code usually on GPL3. My wish is to write blog pages with code snippets of GPL3 projects. For example: write my thoughts / experiences and examples of raw code on the post, then publish the final result on github as GPL3.
Which license should I use for my blog posts? I would like to use one of the Creative Commons licenses (in favor of CC Attribution). I know that CC Share Alike v4 is compatible with GPL3 but I do not understand if this is the case in my particular case.
