One of my coworkers said the same thing. After the third time they were forced to move they caved and bought a condo.

One of my big concerns is that access to psychological benefits of keeping a pet gets to be gatekept by the whims of someone else.

A button to toggle is good design, but it should just default to your system preferences.

My parents own multiple rental properties and completely straight face told me it's a charity cause they rent to people who can't afford homes.

Meanwhile I'm engaging with my mutual aid group every week handing out about 400 meals, and survival gear for people who can't afford anything.

Glad their fucking charity has turned enough profit to pay off the rentals, their main home, and their vacation spot though. /s

WiFi uses a subset of the significantly wider microwave band. Ground Penetrating Radar also uses a subset of the microwave band. While there can be some overlap, the frequencies desired for GPR will very broadly based on what you are looking for, what you are looking in, and how deep you are looking for that thing. The wattage supplied can also differ.

WiFi and Microwaves in general are most definitely not the same thing and I will absolutely encourage you to not set up a 1kW 3GHz jamming antenna for your WiFi needs.

Could you use WiFi for search and rescue? Maybe for a narrow set of circumstances, but in almost all situations a dedicated GPR option will be better.

This also won't identify a victim, only revealing that one exists.

Microwave based ground penetrating radar is actually different from WiFi. Also the technology referenced in the link is a motion based body locator, not an identity recognition device.

This is different technology doing different things than what the original article was talking about.

Rather than banning it this will be heralded as capitalist innovation and will be rolled out in all sectors.

If I've learned anything in the last 6 months it's that the president makes laws.

VPNs will help. The article is only talking about VPN servers based in a location with a geo ban, which, duh. But if you actually use your VPN to be in a different country and not just a different city it'll work fine.

It's no longer the product you bought, eh? Seems like everyone who owns one should be doing whatever they can to get their money back.

Why do you need to identify specific cats over merely the presence of movement or cats in general?

[–] unmagical@lemmy.ml 12 points 2 days ago (1 children)

If all you need is presence detection then a motion sensor would be vastly more efficient.

If you actually need identity detection, then maybe, but you'll still have to have a camera or detailed access logs to associate the interference signature with a known entity and at that point you may as well just put an RFID reader under the bowl you throw your keys into or use facial or gait detection.

Probably not.

This kind of thing relies on the fact that the emitter and environments are static, impacting the propagation of the signals in a predictable way and that each person, having a unique physique, consistently interferes with that propagation in the same way. It's a tool that reports "the interference in this room looks like the same interference observed in these past cases."

Search and rescue is a very dynamic environment, with no opportunity to establish a local baseline, and with a high likelihood that the physiological signal you are looking for has been altered (such as by broken or severed limbs).

There are some other WiFi sniffing technologies that might be more useful for S&R such as movement detection, but I'm not sure if that will work as well when the broadcaster is outside the environment (as the more rubble between the emitter and the target the weaker your signal from reflections against the rubble).

Don't think of this as being able to see through walls like with a futuristic camera, think of this as AI assisted anomaly detection in signal processing (which is exactly what the researchers are doing).

 

I've never been able to make up my mind on whether or not the character has its hands raised or just has prominent ears. Frankly I prefer to believe they are its hands and the character is quite pleased with its star.

Is there a canon answer?
