Public Licence for Code

I saw someone’s licence, and I want to save it for later, maybe:

Publicly listed blog posts on this website are licensed under the Creative Commons Attribution-NonCommercial 4.0 International license.

All code snippets found in my publicly listed blog posts are dedicated to the public domain. If your country does not recognize my right to dedicate works to the public domain, you may also use code snippets from my publicly listed blog posts under the MIT license. Everything else on this website is copyrighted with all rights reserved unless stated otherwise.

I’m not sure which one to use here, maybe just regular CC BY-NC-SA 4.0 as of now. I don’t post source codes, and even if I would, more likely they’ll have their own licenses.
