Comment Re:remote switch (Score 1) 202

The problem is that they installed motion detectors in a place where they needed occupancy detectors. Yes, they both exist, and there is a difference: occupancy detectors don't require motion, just a human-scale heat source. Or, possibly, a vacancy detector—a type of switch that requires you to turn the lights on manually, but will turn them off when the room has been vacant for a period of time.

When I worked for a major photocopier manufacturer, the field techs had a standing order to copy any signs or instructions pertaining to the copier's operation found on or near a copier being serviced. They were to be sent to the engineers, as they represented a design failure. It was felt the copier was a simple device to operate and shouldn't require written instructions at the point of use. They were quite good with UX at the time. For instance, all parts the user could manipulate were color coded at the point of touch: blue for things related to putting blank paper or toner in, green for things related to making a copy, red for things you'd need to touch to clear a jam. (If I'm remembering correctly, it's been a while...)

Comment Re:this is why smart systems are dumb (Score 1) 202

That's not how residential smart switches work. Wire them that way, and the smart system fails every time someone uses the light switch from the wrong entrance to the room. That would violate electrical codes, which require a person to be able to turn on a light as they enter the room regardless of which door they use.

The most readily available, and IMHO best, hardwired residential smart switch in the U.S. is Lutron's Caseta line. When installed to replace a three-way switch, you do one of two things: rewire the other switches on the circuit so they always pass power to the load but also send a signal back to the smart switch over the existing wiring; or replace the other switches with wireless remotes.

The Caseta switches also have a mechanical power disconnect built in, so you can always turn them off. This also lets you disconnect power from the load in a way that can't be overridden remotely. You can reset them that way too, if needed; it's a rare day indeed if so, because they're incredibly reliable. Far more so than, say, Hue bulbs or "smart plugs."

None of which does any good for an industrial lighting setup where each light fixture has an internal smart power switch, controlled via a network. Worse if the light is designed to always reset to "off" after a power outage and can only be turned on from a working controller.

Were you trying to sell a theoretically collectible but notoriously unreliable Italian car made using a mix of Peugeot, Fiat, Chrysler, and obsolete second-hand Mercedes technology?

I suspect that maintenance records are a bit more impactful for Alfas than they are for many other brands.

...it'd be a shame if its resale value were reduced because you didn't have all service done at a dealership so the receipts were certified on our blockchain.

This is an end-run around right-to-repair laws like the one in Massachusetts. You can do the repairs and maintenance yourself, or you can take them to a third-party mechanic... but that means the work won't be recorded on the car's blockchain, and therefore won't be "certified." They're likely hoping that will reduce the perceived resale value of the car. I'm sure that soon enough, they'll start saying "Before buying a used Alfa, always check for full blockchain-certified service records to prove the work was done, and done right by an Alfa dealer."

Wouldn't surprise me if they try to tie warranty service to blockchain-certified service records, but in the U.S. that would probably run afoul of the Magnuson-Moss Warranty Act's tie-in prohibitions.

But social-media sites aren't the town square. The town square is owned by the town, e.g., the local government, for the good of everyone. You can go stand on your soapbox in the town square and hold forth as long as you want; the First Amendment gives you that right.

The fact that no one stands around in the town square to listen to pundits any longer doesn't enter into it.

Social media, on the other hand, is private property, just like the supermarket. You'll find a lot of the general public in the supermarket. But if you stand up and start ranting about your particular fringe beliefs in the middle of the produce section, the supermarket has every right to tell you to leave... and to call the police and charge you with trespassing if you fail to do so. The supermarket may be open to the public, but it isn't a public space.

If you don't like your local supermarket's stance on passionate political discourse by the potatoes, you're welcome to open your own supermarket. It won't be easy, but there's no law preventing you from doing it. Likewise, Facebook and Twitter can tell you to get lost.

In the United States, there is no significant government-owned social media platform.

(I'm sure there are government sites with public comment sections somewhere.) There are no Internet town squares; just privately-owned social-media sites.

Nothing stops you from starting your own blog and trying to get people to read it. There's no law against it. You may have an uphill battle getting people to visit. It may cost you a great deal of money. Depending on the nature of your site, you may have difficulty finding an Internet provider willing to provide service to you, since certain politicians keep trying to make ISPs liable for content by repealing Section 230 and preventing ISPs from being classified as common-carrier telcos (with the attendant regulations).

Impractical isn't the same thing as illegal or impossible.

The fallacy here is that employees are fungible.

Sure, you could hire a new employee in Idaho for a lower salary. You'd lose the institutional knowledge of the existing employee, the knowledge of how the business works. You'll lose their experience. That has a value. You'll have to spend money to train that new employee, during which time they won't be productive. You're taking a risk that the new employee is as skilled and as diligent as the old one; if they aren't, which is quite possible, you may have to hire more people to pick up the slack.

Losing the guy who knows how things work could cause you to miss deliverables. That can lead to angry customers, which means lost sales, which means less revenue.

Employees aren't light bulbs. You can't just go to the store and screw in a new one. Employers who buy into the employees-are-fungible view tend to find that out the hard way.

Comment Plasmids (Score 2) 136

ZyCoV-D uses plasmids or small rings of DNA, that contain genetic information, to deliver the jab between two layers of the skin. The plasmids carry information to the cells to make the "spike protein," which the virus uses to latch on and enter human cells.

Would you kindly get vaccinated?

Not all pneumonia is bacterial. The pneumonia caused by COVID-19 is not bacterial. The pneumonia vaccine does not prevent it. Antibiotics do not treat it.

It’s not pneumonia as you know it; it’s a facet of Acute Respiratory Distress Syndrome. There is no medical cure for ARDS. Severe COVID-19 causes ARDS, which is what leads to the need for a ventilator.
