Except where I'm quoting someone else or state otherwise, I release all code snippets that I share under the Unlicense or the Zero-Clause BSD waiver (whichever you prefer) and I release all other text in my questions, answers, and comments under the Creative Commons Zero. This means you can use anything I post on any Stack Exchange site without having to worry about copyright at all.

The reason for this is because I have not posted any questions or answers with code that adds up to over 300 lines, and because I personally feel that my contributions are small enough that releasing them under a license that requires attribution would be unnecessary.
