My code

All of the code I've written and contributed to Stack Exchange is dedicated to the public domain, or (at your option) available under the terms of CC0.

_{This of course doesn't include code which I posted without being its owner. You can distinguish that code by, for example, the attribution notices (sometimes when answering I might be using the asker's code without explicit attribution but it should be evident) .}
