My good deed of the day: fixing chapter 5 of #paip (a book on #ai using #commonlisp, recently made available under MIT license). The input was basically OCR stuff from a PDF and the output was GitHub flavored Markdown. 3h for 24 pages. I don't think I will be doing any other chapters, though. I'm hoping lots of people will volunteer after reading this message. Original repository here: https://github.com/norvig/paip-lisp
