Can go directly upwind (no tacking required). Can also be applied to boats.

From https://en.m.wikipedia.org/wiki/Sharon_Osbourne
The couple used to physically fight regularly and, according to Osbourne, they would “beat the shit out of each other.” She has described herself as “a beaten woman” when she was at the hands of husband Ozzy where he once knocked out her front teeth. She once retaliated by throwing a full bottle of scotch at his head.

Tbh that doesn’t sound too bad? Like maybe take a nice shower but with cruelty free/plant-based soap that wasn’t animal tested (and obviously there’s no drought concern in this scenario).
107·5 days agogo2rtc, a camera streaming tool that’s useful for security cameras, at least has some humor in their choice — port 1984, of course.

Beautiful!
Sorry you’re getting down voted — lots of replies from folks unclear on what the diffraction limit means, atomic resonances, etc.: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
Parent didn’t say resolve, they said see — you can’t resolve stars but you can most certainly see them.
Light up a single atom enough and you can see it (unclear if this works with a dark adjusted naked eye or if a long exposure is required): https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
No, they’re too small to resolve. You can see small things if they’re bright enough: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
A single atom of gold is far too small for any photon in the visible spectrum to interact with.
That’s incorrect — single atoms can, and do, interact with optical photons.

And the entire field of super resolution microscopy relies on small things (e.g., molecules) interacting with light.
Wait until you hear about the Arctic circle…

No experience with them so can’t at all vouch for them, but it looks like there are providers who will do this.
I self host Immich with an off site backup (=raspberry pi at in-laws house, all over WireGuard). Can’t recommend Immich enough!

Those folks hate cars, not trains. I don’t think we need to worry.
The energy from nuclear reactions can be astonishingly large (compared to, say, chemical reactions).
But atoms are really, really, really small.
Open, or standards-compliant local-only gear is the way to go for smart home stuff IMHO. Never had a problem with a Zigbee, Matter, or ESPHome device suddenly deciding it would stop working because manufacturer said so.
I don’t think this is the black and white issue that the headline suggests.
Homeless advocates appear to be on board with this, at any rate: https://www.kqed.org/news/12047353/heres-why-sf-homeless-advocates-are-glad-lurie-ditched-push-for-1500-shelter-beds
It sounds like the “more beds” campaign promise was somewhat misguided, as slapping a bandaid on homelessness isn’t a fix; more beds is, to an extent, just for show. Hopefully we’ll be able to get actual, research-based solutions to homelessness here.
I’m not super optimistic, but changing course on a campaign promise because the experts and advocates say your current plan is bad shouldn’t be criticized out of hand IMHO.
