my little parser -- tooling is magic
to use demos:
$ npm install $ cd demos $ cd 00-ast $ npm start # opens a browser; click to progress $ # all other demo folders just contain "command.sh" # which assumes `node_modules/.bin` is on $PATH
to read (most) of the talk, see
talk/NN.txt. or maybe you TL;DR
otherwise, the slides are available on speakerdeck.
