The moral of the story is never like anyone. Stay in the house. Become a recluse. Be suspicious of your friends and family.

BTW, don't buy new 8GB GPUs. That's already too little VRAM for some games, and it's going to be the bottleneck making the card useless long before the chipset itself would be too slow. It's a waste of silicon. Previous-gen 12GB and 16GB cards will outlive the 5060 8GB.

Give up on that challenge? Here's how it goes. We're trying to prove

dω/dt = ∇× (v × ω)

so we start with the definition of vorticity

ω = ∇× v

and do

dω/dt = ∇× (dv/dt)

Now we have to use Euler's equation

dv/dt + (v ⋅∇)v = F/ρ

and get

dω/dt = ∇× dv/dt = ∇× (F/ρ - (v ⋅∇)v)

Since we're assuming ∇× F = 0 and the density ρ is constant (since the fluid is incompressible), the first term at right is zero and

dω/dt = -∇× ((v ⋅∇)v)

Now it gets hard for me. I want an identity to help me out! I cheated and looked at this:

https://en.wikipedia.org/wiki/Vector%5Fcalculus%5Fidentities#Vector-dot-Del%5FOperator

where I learned

(v ⋅∇)v = ½∇(v ⋅ v) - v × (∇× v)

Wow! This gives

dω/dt = -∇× ((v ⋅∇)v)
= -∇× (½∇(v ⋅ v) - v × (∇× v))

but the curl of a divergence is zero so

dω/dt = ∇× (v × (∇× v))

or in short

dω/dt = ∇× (v × ω)

as desired! Hurrah!

The magic identity I looked up on Wikipedia is actually a special case of a more general one, which I needed when I was learning about magnetohydrodynamics. So I feel the whole subject of fluid dynamics is where fancy vector calculus identities start becoming really important.

Part of me thinks the digital revolution will come, and when people finally leave these corporate platforms there will be a treasure trove of content explaining what to do next.

And part of me feels that if we don't have anyone evangelizing on the other side of the wall, people will never break free.

I've deleted everything but mastodon, micro blog, and a handful of small community forums. And that's great, but what now? I can only preach to the converted.

If you’re speaking out against #ICE, but don’t believe that ICE should be completely abolished, then I’m confused about your end goal?

ICE was fascist from day one.

Is there a secret threshold of fascism that we’re okay with? Is fascism only bad when it operates out in the open; when it embarrasses us?

Is it the locking humans in cages that’s the issue, or is it that the cage no longer has a blanket over it?

okay, that was weird... friggin gremlins.

sooooo, just forthehelluvit ran `sudo postmap /etc/postfix/virtual` and then `sudo systemctl restart postfix`... magically, the problems disappear and all my old test emails that vanished into the night show up where they should.

@jsonstein

Here are my prediction(s). Within the next 10-20 years:

1. McKinsey or HBR will produce an article (or series) describing the need for critical, analytical thinking among new hires, holding up other companies (say, in Korea or China) that emphasize this.

2. The WSJ will recognize the management techniques at a few successful companies (which they will call "innovative") that involve mentoring new hires to develop critical thinking. This will generate subscription revenue.
