I’ve made some changes to this site, most obviously updating the header image. Thanks to Bryan Mathers. (Why a pigeon?)

Those who look closely will also note that I have also changed the copyright information. No longer is there a Creative Commons license on Hack Education material. This really doesn’t change much, I promise. It just means you have to ask my permission before republishing my work. If you do wish to reprint my writing, please contact me directly.
