    - Timekeeping, the practical parts

    - nuclear weapon, design and practice

    - The educational benefits of doing very silly things

    - brainstorming properly 101, learning not to interrupt other people

    - brainstorming properly 201, “yes, and” isn’t just for improv comedians.

    - basic principles of rocket engine design

    - ADHD and learning to love the fact you just got distracted and remembered the joke about riding bikes

    - artistic hydrodynamics, why watching wax cool is nothing like watching paint dry

    - fire, from kindling to fuel air mixtures

    - DevOps, ITIL, and philosophy, a.k.a. why DevOps should be a goal not someone’s job description

    I’m probably forgetting lots, but that’s sort of to be expected, since I can latch on and care too much about anything that catches my fancy, leading to deep dives into research that leave my life littered with general knowledge and trivia that often has people asking me “how do you know so much?” …

    I effectively collect things I care about enough to learn more than An average person and have also learned how to weave a half decent ad lib lecture, which leaves me with far too many things about which which I could “ give a lecture without prepping”.

    I could give a long lecture on how to use Virtualbox. Spinning up new VMs is now second nature and I could do it with my eyes closed.
