Week 4, book draw winners

Sunday night means entry to this week’s Mind Performance Hacks book draw is now closed. A drumroll, please, while I pick this week’s winners (as before, with an added sort to make the uniq command work properly)… and our two winners are John Doppke and Jose Antonio Ortega. Congratulations! I’ll be in touch to get your addresses soon. Everyone: That’s our last book draw–thanks for playing!
