This is a much improved iteration of the prose version I posted a few weeks (months?) ago.
There a transcript or slides?
https://codewithoutrules.com/pycon2017/slides.html - planning to do a prose version but have limited time this month.
Oh, and since someone asked last time: in my spoken version I explain I’m not a fan of Lean Startup, but it’s a relevant well-known example of the Understanding Users testing gaol.
