Technically more of an engineering / maker channel, but Xyla Foxlin is great. She does occasionally swear, but a 12 year old has probably heard those words before. Yeetmas, where she launches a Christmas tree rocket, would be a good place to start. (Not a Christmas tree themed rocket, a decorated pine tree on top rocket motor as long as your arm.)

this fits with my understanding of cybersecurity and why we don’t mix data with directions.

Didn’t we learn this lesson 60 years ago when phone phreakers used their blue boxes to make free phone calls?

For anyone who hasn’t heard this one: When the Concorde flew at supersonic speeds, the airframe got hot enough that it expanded about a foot longer than it was on the ground. This opened up a small gap between the flight engineer’s console and the rear bulkhead of the cockpit. On each plane’s final flight, the flight engineers stuffed their hats into the gap, which then closed up after cooling off.

I went to college in Ohio. I much preferred 30° and precipitating to 35° and precipitating, especially as a pedestrian walking to classes. Snow you can brush off before you go in, a cold rain just soaks in.

You can probably add “website” to the list.
