Public cloud, public social media, public dating apps. It sounds unhinged at first but tbh I think creating alternatives with no profit motive could have extremely positive downstream effects to every aspect of society.

There’s a lesson here for Canada, if the good people at the CBC want to learn it.

If your law is good when there are good people in office, but dangerous when there are bad people in office, your law is bad.

It's amusing that Point Nemo is 1) the location of the city of R'lyeh and 2) the point where we aim for our deorbited junk to crash into the ocean. So we've been bombarding R'lyeh from orbit for decades now and sooner or later something down there is going to get cross.

I worry that escalating war with Iran will be used to whip up more fear and hate for non-white immigrants, particularly those of Arab descent, and be used for unjust deportations.

Adam and Eve had no stuff, and were happy.

And so, Satan invented stuff. This caused greed, and envyβ€”and worst of all, "needing to remember where you put the stuff."

But our parents could still see their stuff, and inventory it. They weren't totally miserable.

And so, Satan invented data.

The biggest mistake made by cyberpunk media of the 80s and 90s is that they didn’t anticipate the power of NIMBYs.

On the other site I said Visa and Mastercard are the unwilling de facto rulers of the adult industry.

In this thread, we’ll dig into adult industry’s most exciting layer: financial plumbing! and explore weird content banned not by law, but by interpretation of card rules. 🧡

Canadians clutching their pearls about ICE barely know the Liberals are pushing through a bill right now giving the gov the ability to check your mail, get your IP and internet history, and makes immigration and asylum seeking way more difficult

just watched a video on Obsidian that described it as "future-proof," i.e. it uses open file formats so you can easily migrate to a different note-taking app & you're not locked in. could borrow that to explain bluesky

You Should Be Afraid Of The BYD Seagull China’s best-selling car is a downright dignified driving experience. I don’t know if Western automakers can replicate this experience at this price.

To understand why Western automakers are so afraid of China's best-selling EV, we drove one on its home turf.

It's simple. You get a dignified driving experience for $8,000. If you want that in America, go to the used car lot. insideevs.com/features/761...

Teachers Are Not OK AI, ChatGPT, and LLMs "have absolutely blown up what I try to accomplish with my teaching."

Also, research shows that when anti-violence shelters come to a region, the murder rate against women ticks down a tiny amount, but the murder rate of men by women falls off a cliff.

When women have other ways out of a bad relationships, they take them. When they have no hope, they kill.

Also, I don’t think that the startup current for a compressor is typically included in load calculations, at least here in Canada. My parents have a geothermal heat pump with a startup current of like 150A, and that’s totally fine on a 200A service with a bunch of other electric loads.

You could even have them share a circuit with the stove, for example; no harm if the back up heat turns off for a little while when you’re running the stove, especially because they’re most likely to turn on overnight when people likely aren’t going to be cooking anyway.

What about putting an EVSE-style load management device specifically on the backup heat strips? Depending how big they are, that could be enough to get you down below the total load. Since all of the them I’m aware of are essentially just resistive heaters, it shouldn’t hurt anything.

Do you mind if I ask: what are the primary contributors to those peaks?

Ughhhhhhh that sucks. 800A service is *ridiculous*, too–that's almost 200kW of power! What do they think you're running, a DC fast charger?!

I think this is the company I was thinking of? www.pspproducts.com/load-managem...

It really does seem to me that this needs to just ... be a product though.

For that many subpanels, it’s probably worth talking to an electrician about how much it would cost to get field approval for something a bit more custom? You could get a bunch of listed relays/contactors and a PLC in an enclosure maybe?

Yeah, agreed. Honestly, other than the "integrating with various bespoke vendor things" part of it, it wouldn't even be that hard to make a product out of this–though I'm sure the various certifications would be πŸ’Έ. I don't have the time/expertise to found a company, but I hope someone does!

As for the "why verified people"–that's a great question, and one I'd love to know more about myself. I have some theories myself, but since I don't work at Bluesky, they're just that, theories and guesses.

To your first point: πŸ’― absolutely–scams that are driven from organized crime pose as anyone that they think will allow them to obtain funds; the war in Ukraine is/was another one, for example.

The only similar thing that I know of off the top of my head is www.openevse.com - you can publish a MQTT topic of "current power draw for the house" and configure it to dynamically adjust the charge current to keep the total power under a limit.

(It also supports "only charge from solar", too!)

Ah, I see what you mean; yeah, this is still throttling at the breaker/outlet. It would be *really* nice to have the ability to control that stuff from inside the building, yeah.
