Everything I know and all the work I do springs either from knowledge I gained from others, from the culture in which I have grown up, or from triggers the world around me presents. Unless there is some other copyright holder, all the work on this site is available for you to use without payment under a Creative Commons License.
I use what I call the "self-patron" model: I am retired, but I am still doing research and writing. I've set up this donations page as an experiment. I vow to use all donations either to pay for infrastructure to make my writings available or to make more of them.
