Something I noticed as a gotcha running a RISE presentation on MyBinder last week was that with the slides running in the browser, a five minute wait between me firing up the Binder and checking the slideshow worked, and my interactive cells some way into the presentation, the Binder timed out while I was presenting which meant either skipping on the interactive slides or restarting Binder (and Sod’s Law getting put onto another stack and requiring another build).
Would some sort of background keep-kernel-alive process be possible that could be started when launching the slideshow and killed when it’s closed?
