I dislike the entire notion of "intellectual property". Unfortunately copyright is applied automatically, and it's not possible to explicitly place something into the public domain in the UK, so I have to do the next best thing and use CC0, as follows:
To the extent possible under law, I have waived all copyright and related or neighbouring rights to everything published on this website (not including works created partly or wholly by anyone else). This work is published from: United Kingdom.
While you're not obliged to do anything if you copy my stuff, it would be nice if you give me credit, and notify me if you use it for anything interesting.
