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.
The energy from nuclear reactions can be astonishingly large (compared to, say, chemical reactions).
But atoms are really, really, really small.

Move ‘em 2 millimeters in the wrong direction and you’ll have a bad time
Are you referring to getting, I dunno, yogurt in places outside the digestive tract?
My understanding was that gut bacteria play a pretty crucial (beneficial) role in overall health, not to mention the whole gut-brain stuff.
Pretty sure those “horrible little scalawags” play some pretty crucial roles in the human microbiome…
Or just a San Francisco resident — these ads are everywhere on BART (+Muni I guess) right now. (As far as ads go, they’re pretty good I guess — and no, I don’t even use them, much less work for them.)
6·17 days agoZigBee router thing:
I’ve been happy with the SMLIGHT SLZB-06M. You can easily flash firmware, and it has PoE which was important for me. I believe it also supports Thread, but I haven’t tried this yet (and I’m not sure if it supports it at the same time as Zigbee).
Zigbee smart plugs from Third Reality have been pretty solid in my experience, and they report power usage.
For circuit breaker level monitoring, I have an Emporia Vue2. I have it running esphome, completely local — unfortunately this requires some simple soldering and flashing, so it’s not turnkey. But it’s been rock solid ever since flashing it. (Process is well documented online.)
I’ve had decent luck with cheap wifi Matter bulbs, but provisioning them is finicky, and sometimes they just crap out and need to be power cycled; Zigbee bulbs (e.g., Ikea) have generally been reliable, though sometimes I’ve had difficulty pairing them initially. After power cycling a Matter WiFi bulb, it takes a while for it to respond to Home Assistant; Zigbee bulbs generally respond as soon as you power them on.
I have a wired smart light switch from TP-Link/Kasa (KS205), and it’s been completely hassle free (and totally local — Matter over wifi). The Kasa smart switch dongles I have work flawlessly but need proprietary pairing, and I’m afraid to update firmware in case they lose local support.
Good luck! Fun adventure :)
1·18 days agoMy recollection is that the DVD included that library, but it’s been a while…
Most Linux filesystems, being case sensitive, won’t find the
SUDOcommand.
I think it’s probably better to amend it to, “if it was covered in poop would you get rid of it and not replace it?”
Not parent, but when a minute isn’t quite enough, 77 seconds might do the trick. Multiples of eleven are quick to enter, and with a simple nuker with no “minute” button, 66s is easier than 1:00.
I think a lot of companies view their free plan as recruiting/advertising — if you use TailScale personally and have a great experience then you’ll bring in business by advocating for it at work.
Of course it could go either way, and I don’t rely on TailScale (it’s my “backup” VPN to my home network)… we’ll see, I guess.
…are Turing Complete, so what you can do with them is exactly equal.
But they’re only equal in the Turing complete sense, which (iirc) says nothing about performance or timing.
It’s a pretty standard bandwidth/latency tradeoff in my view: email is high bandwidth (it’s in writing, you can re-read, etc.), whereas phone is low latency (several back-and-forth explanations can happen in seconds). Each has its place.
If social anxiety is a factor, that’s a perfectly valid, but separate, issue.
8·1 month agoWell, yeah — dude’s brake cables are missing!
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/
