Move along, there's nothing to do here.

Aside from knowing this: everything I ever post, originally from me, on any website from the Stack Exchange network, you're free to do whatever you want with it. Put credits if you'd like (I always do when it's something that was hard to do by the person), but let's say the license is CC0 (https://creativecommons.org/publicdomain/zero/1.0), not Stack Exchange's default one (more on that here and here). As I can't put the license for the answers away from them (here), I'll also say it's all dedicated to public domain, hoping that helps in any way, since it's not a license.
