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 work for a company and use a fair piece of my income for producing these works. I've set up this donations page as an experiment. I vow to use all donatiions either to pay for infrastructure to make my writings available or to make time to create more of them.
