We talk about it all the time. For a little while I was playing with a set on fundamental block cipher cryptanalysis (Matsui, differential, etc) but I put it down. When we interview people for the podcast, I'm going to start asking them for suggestions for new challenges; for instance, I'd love to see if there's dumb lattice crypto bugs we can capture.

I'm curious to know what podcast you are referring to ?

appreciated !

Just gonna say two things here: 1) stop! Collaborate and listen. And 2) I never got set 8 even thought I emailed!
