I keep it because it can be a useful way to get in touch with people I would only know professionally. For example, I used it to reach out to employees of a company I was applying to that used to work for the company I was trying to leave, to get a more honest opinion of the place. Past that though, I never even look at it, and I do actually try to keep my connections limited to people I know.
I've had bad luck with Linux automatically using the dGPU even though I have to do this because I'm using a Tesla P4 which doesn't have display output.
As funny as this is, it's also a very common logo, being a varient of the Penrose Triangle. Honestly more shocked they didn't spring for some better graphics...
When wind speed doubles, the energy it carries increases eightfold,
Edit: I'm wrong, see edit below!
Huh? Kinetic energy increase is square, not cubic.
KE=1/2 m v^2
So every doubling of speed should increase the available kinetic energy by 4 times, not 8. 3 times the speed is 9 times the energy.
Granted there are probably some efficiency gains in excess of this at the low end, but as a rule that's just wrong.
Edit: Cool, I learned something new! I neglected to consider it in terms of power, just thought about kinetic energy.
So something like:
KE = 1/2 m v^2
= 1/2 ( rho V) v^2
= 1/2 ( rho A d) (d/t)^2
= 1/2 rho A d3 1/t2
Where
P = KE/t
Thus:
P = 1/2 rho A (d/t)^3
= 1/2 rho A v^3
Lots of other aspects I'm sure I have wrong, but I see how the cubic came to be.
TIL West/East Antarctica is effectively just left/right of the 0°/180° longitudes.
