  • Lots of folks say to cut news intake (however it is happening). This is correct. Everyone suggesting you pick up other things, very wise.

    If you are burned out of all these topics entirely, this is probably enough/right. If you still, for whatever reason, wish to engage with the unending crisis:

    • Sit down and prioritize. Pick a narrow issue, find good sources on Precisely that, and read/engage with only things that fit. RSS feeds support keyword filters.
    • Find longform content related to what you care about. Books, long podcasts, etc. Shortform only has time to make you panic. Longform can actually give nuance, solutions, and an honest accounting of the situation (it doesn’t always. But you have a chance.)



  • Thank you. I could be persuaded to change the title, though I don’t think I have been. (You are perhaps not trying to, but I’ll record my reasoning anyway.)

    Re: nobody is motivated to do this. True, and doesn’t contradict the title or content. Anybody could drive out and start toppling power poles and poisoning the water supply, fortunately most people are mostly good.

    Re: some houses are well insulated. Congrats on your nice home! Many dream of having their own space someday. I think the most interesting case is in an apartment/condo/high density complex. In this setting, you have:

    • the layout of the entire building, including other rooms. (modulo furniture and dustables; the walls are public.)
    • many routers all over the building, overlapping and generally at different frequencies. When I AirBnB, I often see dozens of different networks from my bedroom. Note that for this style of attack, you don’t need to connect to anything.
    • thin walls between units (often cheap).
    • some incentive towards snooping. Who stole your packages? Which neighbor keeps letting the dog poop at your window?

    Re: training required and the field of view This I find most compelling. I am interested in how much legitimate use is required; can we simply make login attempts? Or does it take somebody logged in? It’s hard for me to tell how customized the model must be (this is a setting where data is reasonably easy to generate in a lot of settings; perhaps enough so that, given a model slightly larger, we get something general?).


  • The original title was substantially less clickbait; I amped it up in the hopes of a reply like yours.

    If you have a moment more to enlighten me, I think you’re claiming:

    1. This technique is location and person specific; the models don’t generalize if you move the router or change the people (and retrain on less data)?
    2. This method doesn’t determine where folks are (even when used with multiple routers) to any useful precision? (Forget who, you can guess whose in your neighbors house)
    3. This method is nowhere near getting plausible pose data?






  • (Gonna also note that desalination has costs and downsides. Energy is only recently free and still has externalities, materials are still scarce and have to be prioritized, and it really isn’t that much fun hauling water, cleaning filters, or building pipes. I think in almost all arrangements of how we spend humanities total effort, we wont be piping that much pure water into the middle of the Sahara.)
