IIRC, there’s a harder, trusted process for measurement. But an easier method that has gained widespread adoption, and that method is what has been called into question.

Because of how wide and thin it is, it looks like a phased antenna array to me. It’s a way to create cheaper, performant antennas. You see this form factor with a bunch of RF applications in UHF to EHF range.

Here’s an example of a random mmWave radar board. Imagine a plastic case over this to keep out dust and rain.

The large flat one looks like radar to me. I hadn’t heard of radar being used with PTZ cameras. But you can also use it standalone to measure traffic flow.

If it isn’t radar, it’s something with a large, flat antenna (probably a phased array). The other two options I can think of are a long-range RFID scanner or a point-to-point network connection.

How does this handle grid power outages?

In my area, you’re required to prevent back feeding if the grid goes down (otherwise it can be hazardous for the linemen repairing the issue).

This. Smart thermostats are pretty straightforward to install.

For the ultra wealthy, the value of their assets goes up faster than the interest rate of the loan.

I don’t know anything about that specific model, but one option for most mini split and window AC units is to get a smart IR blaster.

It’s the “adventure of a lifetime.”

So they can claim they don’t have authority to bring them back?

Alternatively, “No” is a complete sentence.

Also soy milk and almond milk.

Specifically, this shows current and future wildfire risks.

Is this a cool innovation? Yes. Over 100Gb/s wirelessly in a data center would be really cool.

Does this “rival fiber optic speed”? No.

Lay people don’t get how crazy amazing fiber optics is. Right now you can buy an off-the-shelf optical transceiver that does 800 Gb/s with a pair of passive fibers over 2km using a single wavelength. Why does it use a pair instead of a single fiber? Is 400 Gb/s the max you can transmit on a single fiber? No, it just makes the transceivers easier to make. I don’t know what the upper limit is per fiber, but it’s probably north of 100 Tb/s.

If this piques your interest, check out the Grace Hopper cable. It’s designed to carry 352 Tb/s across the Atlantic on 32 fibers. With all the protective layers, the cable is about the size of a garden hose.

Smart switches for the lights. We can turn off all the lights in the house from bed.

Internet access is increasingly becoming as crucial as any other utility. For some people, losing Internet might interfere with work, school, or medical devices.

It’s not “the end of the world” if my electricity is out for 5 hours, but it might cost me hundreds of dollars in spoiled food. It’s not “the end of the world” of my Internet is out for 5 hours, but it might “cost” me PTO.

You mean the journal article? It gives good details about how it generated its numbers for different building materials and methods.

Here’s the actual journal article. https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0328965

They didn’t make RAM. But they tried to see if this fungus could act as a memristor. A memristor is one of the four fundamental electrical components, along with resistors, capacitors, and inductors.

One of those tests was a volatile memory test. Think of it more like storing a single bit vs with RAM where you have an addressable space of values you can set and read.

Amen!

Waves clean cast iron in the air.

This article smells fishy. Another commenter mentioned the source not being reliable. But the whole concept of “drawing to a plan to invade Greenland” sounds off to me. Remember the US probably already has detailed campaign plans for something like this.

Part of responding well in a crisis is planning the response ahead of time. In a military context, that means wargaming and campaign planning. I expect the US military has offensive and defense plans for a wide range of situations. That likely includes everything from options for offensive actions in China to plans for defending a conventional invasion from Canada.

To be clear, I’m not picking on the US here. Every professional military in the world is going to do this sort of preparation. Part of a prepared military is having a plan of action in rapidly developing situations.
