I like to have multiple versions of my talk so I can slide into any time slot at a meetup or conference. Time to rehearse that 30-min presentation again, so I'm ready later this month 😃
@simonbs that’s smart! (The 30- and 35-minute presentations include video?)
@ico Yep, they all do. Lots of video.
@simonbs what a good idea! Gonna steal that.

@simonbs this is a great preparation.

How does the size difference of the 15 min version come about?
