I believe it’s that older HVAC controls don’t have a true ground/neutral, so they can’t actually consume power. Thermostat is (used to be) basically just a remote switch, just connecting the signal wire to its various functions, so there’s no need for it to have any kind of power. More recent systems have a ground (C wire), so you can draw power between the 24V R wire and the C common/ground. Some systems even put mains voltage on R.
After I got pm2.5 into homeassistant, I started buying MERV13 filters for central air. A jury-rigged system for turning that on/off graduated to a proper wireless thermostat, and I now have an automation that turns the fan on at pm2.5>10, then back off <3. A good 5" filter will last 9 months before the time-to-clear gets to be too long. 3 ug/m3 can be a difficult lower bound, and if it seems like we get into a bad outside aq period, I’ll bump it up to 6 with a trigger at 15. MERV11 could not hold even 10 ug/m3.
My indoor aq sensor spikes from fireworks on 4th of July and neighbors cooking on the other side of the shared wall. Most interesting to me is that aq - both inside and out - is worst overnight, not at rush hour.
ed: I use https://map.purpleair.com/ for outdoor air quality. Their global data can be polled with a (free) API key, and as long as you don’t poll too often, the free data limit will last years. Someone wrote an HA integration for purpleair, but it polls to often and rapidly exhausts the free data.
Politicians, and even corporate C-suite, often confuse “cheaper to buy from the incumbent” with “incumbent has impossible-to-replicate technology,” completely ignoring that it’s way easier to invent something the second time.
Technology might have been a barrier in 1960’s China, but they’re a peer nation today.
There’s a wider spectrum of “consuming audiobook” than of “reading.”
Listening to that audobook so it’s easier to take notes? Definitely as good as reading.
Audiobook on while you’re on the treadmill? I guess there’s some people who can read on the treadmill, so maybe it’s similar, but it strikes me as very different levels of attention and likely recall.
Audiobook on while you do chores, cook, or write some other project? Definitely not equivalent to reading.
I know a couple of people IRL who never seem to have a positive reaction to anything. The proverbial “every silver lining has a cloud” people: got a raise? just means more taxes. Sunny day? skin cancer. Cloudy day? cold and mud.
For the particular people I know, it seems like a self-esteem thing - like they don’t feel themselves worthy of happiness, so they have to preemptively destroy anything positive. Or maybe just be contrarian to prove they’re smarter than everyone else. It’s exhausting.
Goodhart’s law: When a measure becomes a target, it ceases to be a good measure.
Used to be that a college degree indicated people with time, money, and drive to put four years into study. It was a good measure of the “right” kind of person. Now it’s just another job requirement and doesn’t indicate anything.
When she first showed up, I remember one particular picture of her being all over right wing media. Not the most flattering picture, obviously. She was smiling especially broadly, showing lots of teeth, eyes wide open (“bugged out”). Sometimes associated with speculation that she might have Graves disease or some developmental disorder.
No question her appearance has made the media give her more time than they might, but she has a compelling story and she’s connected with millennial voters much better than her septuagenarian peers.
Interestingly, the specific article cited is more making the case that all passenger cars are bad, and we’d be better off with e-bikes, transit, and walkable cities. i.e.: I don’t think hes saying 'EVs are worse than ICE," which is where the ‘lifetime emissions’ line usually goes. He’s saying “fuck cars, EVs not excepted.”
Does anyone know if this is a widely used app? All the stats I see on github or lemmyapps make it look very small.
Just what I was looking for. Recently got a kobo for experimenting, and just starting to figure out how to integrate it.
I’d still rather physical books, but sometimes there’s just too much premium for too shitty of POD trash.

Not even solar panels on the roofs.
These are computer monitors, not TVs. Plugging them into a Windows box triggers Windows to silently install their “driver,” which silently installs a handful of other startup apps. It’s an escalation of the smartTV-wifi path.
Having not gone to any of my 40-or-so reunions, I feel like they would only get interesting after 20. Maybe 30. That’s long enough for everyone to have finished all the school they’re going to do, for people to have moved beyond their first jobs, or even first careers, and to have experienced enough life to really become their own people.
I like Cory Doctorow’s take: AI is good for single-use, personal code to solve an immediate problem, and terrible for long-term, production projects. I imagine there’s a bunch of neophytes out there who use AI to create their first project, find out that github exists, and thinks someone else must be having the same problem they just solved, so why not release it to the public?
People know that listening to music supports the creator, and they don’t like supporting shitty people. There’s tons of people making really good music, so you can satisfy both the desire to enjoy good music and support good people.
Dunno how well it would work with kubernates internal networks, but my DNS is configured with different views for internal and external clients. So, when letsencrypt does a lookup, they get the external IP, but when an internal client looks up the same name, they get the internal IP. TLS is happy, because the certificate matches the name. I’m happy because it works even when the ISP is down.
Can’t imagine they would be personal-use lockers, especially not with doors that display the contents. Have to imagine that they were no-lock ‘lockers’ to hold common-use balls & gear out of the weather when not in use.
I suppose they could be rental/honor-box - insert quarter to get ball, please return when done, but I don’t think I’d call that a ‘locker.’
As someone with a collection of a couple hundred CDs and another hundred or so DVDs filling my closet, I’m not really sure everyone appreciates the logistics of holding physical media for a couple-hundred-game library.
All the thermostats I’ve looked at - definitely all the “smart” ones, accommodate all manner of existing wiring. If you just have a ‘normal’ HVAC with a single aircon, single furnace, and fan, or one with heat pump, backup furnace & fan, then any thermostat out there will work. If it has internal logic, it’s going to have a place for batteries, but it will also (probably) have the capability to run off furnace power, if you have the right wires. Smart thermostats will report their battery state to homeassistant, or you can just change the battery when you switch it over to heating for winter.
Swapping a thermostat is pretty easy - it’s literally ‘connect red wire to terminal labeled red.’ It’s complicated if you care what the red, yellow, blue &c wires actually do, but the install itself is just color matching.
If you have an extremely high efficiency HVAC, or one with multiple heat sources & multiple compressors, then there may be more than the usual 6-ish wires, but even there, it will be an exercise of taking wire from its current, clearly labeled terminal and plugging it into the same labeled terminal on the new thermostat.
If you can stick with the same vendor for a thermostat upgrade, it may make the job very easy. I replaced a Honeywell programmable thermostat with one of their smart thermostats, and I didn’t even have to change wires. Both thermostats plugged into the same backing/terminal block. I literally pulled the old one off and pushed the new one on in 10 seconds. No tools.
