"I have been out of IT world for a few years but your talk kept my attention!"
-John McGinley, 2018 DevOpsDays conference
Lightning and Ignite talks are very short (1-5 minutes) presentations with few (or no!) rules. While I sometimes improvise a talk in the moment, my current, prepared Lightning/Ignite talks are:
Science, Software, and Scissors - An educational, enjoyable, and highly interactive talk that compares the scientific method, software development, and roshambo.
Inductive Reasoning - A fun, interactive talk that introduces and explains inductive reasoning: "Making general conclusions from specific knowledge".
