I believe you can achieve the same result in your home by adding a sheet metal roof, metal cabinets, and refrigerators along every wall.

That's probably it. Perhaps I want some decorative brushed aluminum sheet metal instead of drywall...

Aluminum siding works pretty well!

In a 5-4 decision in https://en.wikipedia.org/wiki/Kyllo_v._United_States , the SCOTUS determined that police can't use thermal imaging on a house without a search warrant. I wonder what the vote would have been if the justices could have seen videos like this.

Sometimes I wonder is this could be mitigated by literally covering your walls in aluminum foil. Maybe those "tinfoil hats" are on to something.

Just get aluminum siding, which was very popular before people switched to vinyl.

Why do you believe any of those names are not American?

They're all American in some measure as they are all living in the US at MIT. But they are clearly immigrants or the descendants of immigrants.

I mean... in 2016 1.2% of Americans were "American Indian", so outside of that small group everyone is "clearly immigrants or the descendants of immigrants".

It's pretty bad form to look at names and assume that someone isn't an American.

My Lowe's and Home Depot both have free Wifi. I use it all the time to use their app or site to find the location of items in store (obv. can't talk to humans).

Good luck with that. I tried unsuccessfully, to buy an item at both Lowes and Home Depot but nobody was able to determine where in the store the item was even when I pulled the information up on my phone.

Both the Lowe’s and Home Depot by me have the aisle/bay listed on their website. It’s usually super convenient, except for their numbering of end caps. That time it took a couple of tries until I found an employee who knew what was meant.

One of the Home Depot's in my area had broken Wifi for multiple months. You could connect, and go through the disclaimer, but nothing was reachable through it. Particularly annoying because the other store, which is about the same distance away, has working Wifi but horrible reception. Since I'm occasionally in each, I had to remember to forget the Home Depot Wifi and add it back in depending on when I wen tto different stores.

I've noticed, recently, that literally every major chain store I go into blocks my cell signal. I get full bars outside, perfect LTE, and about 5 ft past the glass doors, I'm suddenly cut off. Specifically, Meijer grocery stores and Home Depot are the worst offenders. Coincidentally they offer free in store WiFi to track me with, so I turn off my wifi radio on both smartphone and smartwatch before walking in the door…

I haven't noticed it myself. Cell phone still works inside my local home depot. Back in college the engineering building used metal plates as the outside facade, combined with concrete construction. It had a side effect of getting rid of any cell phone reception as a result, unless you were beside a window. The building was built before 2G cell phone service was a thing, so it wasn't an intentional thing.

Go to hardware store (Home Depot would be ok but watch for poor cell reception). Buy 100 rolls of chicken wire and several gross of outdoor cable clips. Tack up all over outside surface of your house.

Steel roof trusses, steel roof material, and racks and racks of steel shelving don't exactly make for an ideal radio signal environment. They aren't blocking signal, you are standing in an un-intentional Faraday cage. It likely has more to do with who your carrier is and what frequency your phone is connecting at. And FWIW, you don't have to be connected to a store's WiFi for them to track you - https://www.fastsensor.us/en/ is only just one of the many companies who don't require your cooperation to track you in-store.

Seems like a sound investment!

It's somewhat similar, but AT&T (and Apple) have forced my iPhone to always join the "attwifi" public wireless networks (present in Home Depot, airports, etc.).

I can't make my iPhone NOT auto-join it, no matter how many steps, guides, hop-on-one-foot voodoo that I've tried.

The wireless network is terrible at everything except signal strength.
