  • On a “respond to an individual query” level, yeah it’s not that much. But prior to response the data center had to be constructed, the entire web had to be scraped, the models trained, the servers continually ran regardless of load. There’s also way too many “hidden” queries across the web in general from companies trying to summarize every email or product.

    All of that adds to the energy costs. This equivocation is meant to make people feel less bad about the energy impact of using AI, when so much of the cost is in building AI.

    Furthermore, that’s the median value–the one that falls right in the middle of the quantity of queries. There’s a limit to how much less energy a query to the left of the median can use; there’s a significantly higher runway to the right of the median for excess energy use. This also only accounted for text queries; images and video generation efforts are gonna use a lot more.

    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.

    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.






  • 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’m generally pro research, but occasionally I come across a body of research and wish I could just shut down what they’re doing and rewind the clock to before that started.

    There is no benefit of this for the common person. There is no end user need or product for being able to identify individuals based on their interactions with WiFi signals. The only people that benefit from this are large corporations and governments and that’s from them turning it on you.

    Continued research will ease widespread surveillance and mass tracking. That’s not a good thing.



  • That was my proposed alternative I encouraged my friends to call about. I don’t know how it wasn’t obvious that if your goal was to increase pedestrian safety and encourage visiting your park in the middle of downtown (which was the public justification in the survey) that the best way to do that would be to get rid of the 2 highways trisecting your park. Grass them over to both remove traffic and increase park space, install meandering leisure paths through a history walk, and have local Coloradoan artists produce for a dedicated Coloradoan history sculpture park.

    Oh, and if you really, really want members of the public to use your public park get rid of the helicopter parent rangers that yell at you for touching the oldest tree in Denver or for falling asleep, get rid of the signs that forbid standing still or loitering (at a fucking park of all places), and don’t close off the grass areas periodically.

    You could even go so far as to install more trash cans or make the bathrooms available 24/7.

    It’s not that the public didn’t care about your fake liberty bell, it’s that your park is kinda a hostile environment with shitty infrastructure.


  • Speaking of not teaching things kids have to unlearn later, I’ve often wondered why we don’t just start teaching math with the expectation that you solve for “x”.

    i.e. Instead of

    2 + 3 = 
    

    Write

    2 + 3 = x
    

    This would prime the child to expect that math is about finding an unknown and you’ve already introduced the unknown that will be most prominent in their academic career. This will also reduce the steps necessary when teaching how to balance an equation as you no longer have the “well actually you were always solving for ‘x’ we just didn’t write it, so you didn’t know, also we’re never going to use ‘x’ for multiplication again.” stage.

    But I’m not a teacher, parent, or child psychologist and this is just my blathering hypothesis based on watching my peers struggle with math for years.




    • History shows everything I’ve ever been to including the “nope that top result in my search engine actually didn’t contain the search string anywhere in its contents and is thus useless to me.” pages
    • Bookmarks are for things I routinely go to for years
    • Tabs are useful results for the projects I’m working on now.
    • Pinned tabs are the pages I visit multiple times a day.

    None of those is a substitute for any other.
