If you're interested in DB internals, stop what you're doing and watch @CMUDB Quarantine Talk from Nico+Cesar about @SQLServer's Cascades query optimizer: https://t.co/FCdsbHHEaD

Many talks this semester were good. This one is the best. My thread provides key takeaways

Play is our future

Skill is measurable w/ two resources 1) time, 2) energy

Players whose actions make better use of these resources can be defined as optimal. This is not subjective

Time (faster)/overload/conscious/stress
Energy(easier)/underload/unconscious/low anxiety

Orgel's First Rule:

"Whenever a spontaneous process is too slow or too inefficient a protein will evolve to speed it up or make it more efficient."

Faster (speed/strength)-Deliberate Practice
Easier--Play

Overload (D.Practice) builds faster=hypertrophy and results in measurable selection resulting in problems such as Relative Age Effect, and players with very fast cars saddled with inexperienced drivers

It's more likely to be wrapped around a tree than finish the race.

as Orgel says, if we allow it, play will produce faster and easier

Kids in play build the driving sills first, in Go Karts, like Ayrton Senna

Big brains, slow cars, easier

But where speed is limited by physics,

Ideas are plentiful and under resourced in US youth sport

Almost every coach will agree w/ the following

Competition is important
Training is more important than games
Play is more important than both

But,

the big thing is to keep the big thing the big thing

The key supporting effort appears to be underway on Trump’s operational timeline

As we emphasized yesterday, J.E. Dyer commands us: "But do hold the line."

Yoga employs more Americans than coal. But compare and contrast 1/2

and 2/2

I think many of us carry in our minds an image of the US economy that looks like this

when the reality is this

and this
