Coming from Debian, it was…not expected. I understand how and why it happened, but the user experience was surprising.
Debian keeps the previous kernel around, which makes perfect sense to me — in the event that a kernel update borks your system you can just load the previous one. This would probably only happen due to out of tree modules (looking at you, Nvidia…).
Linux distros can still do…questionable things. In grad school I tried Arch for a bit, and I once was late to a video call because I had updated my kernel but did not reboot. Arch decided that because there was a new kernel installed, I didn’t need the modules for the old — but currently running! — kernel, so it removed them. So when I plugged in a webcam, the webcam module was nowhere to be found.
But yeah…somehow, still not as bad as Windows updates.
Our Internet went out for a few hours today, so naturally my smart switches, lights, cameras, motion sensors, door sensors, and power monitoring… continued to work as of nothing was wrong.
Home Assistant is great, and using local-only devices is awesome. If my smart home stops working it’s my own fault, not some 3rd party.
Your numbers seem reasonable — more intuitive for me to work in terms of pressure. Atmosphere is (roughly) 1e3 Torr, good UHV can be around 1e-10, so that’s 13 orders of magnitude, which is (roughly) the same difference that you calculated.
Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.
Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.
*Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.
From TFA:
“I have failed you completely and catastrophically,” Gemini CLI output stated. “My review of the commands confirms my gross incompetence.”
99 what you did there…
(I know, IC isn’t valid Roman numeral representation of 99, but it was the only joke I could think of.)
Because it’s not an X at the end, it’s a Greek chi. Same with the arXiv preprint distribution — it’s “archive,” not are-ex-iv.
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.
ethic cleansing
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).
go2rtc, a camera streaming tool that’s useful for security cameras, at least has some humor in their choice — port 1984, of course.
(…I think you may have gotten whooshed…)
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.
Yeah it’s missing the text, “…then the Planck X would be…” for the first two.
And a big plastics shill, unfortunately.
For back-of-the-envelope or mental calculations, pi is often 3 or 10^(1/2).
The latter is better than 1% accurate, and has nice properties when doing order-of-magnitude/log space calculations in base 10.
ZigBee 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 :)
