  Yes I simplified. Some(? I’d hope all but probably not) new fobs do turn off (ignore the car broadcast) if they are not moved for a time. I proved this to myself with my 2020 car by putting my keys down by my car door, I could only unlock the car for a minute or two after I put it down, after that keyless entry didn’t work until I disturbed the fob to wake it up.

  This is to mitigate the relay attack at home (and I’m sure other times, like if the key is in a purse), one avenue was that attackers would count on people hanging their keys by the door, so accessible to selective standing on the stoop with a relay. By turning off at rest they can’t be exploited this way.

  Older fobs never turned off - so they are constantly broadcasting the signal for the car. Newer fobs do turn off when at rest so they’re less risky, but if say it’s in your pocket it’s constantly moving so someone could still relay it to steal your vehicle, assuming they get close enough to you.

  The faraday bag is good for older fobs or if you think you’re at risk of a key relay attack.

  All that yes. The Wooting One (original that uses IR light) let you use buttons to simulate controller axes, change how hard you need to press to activate, and add second functions to keys. It was an interesting idea but I found the gaming part the original keyboard to be only usable in a limited set of games as it’s not as sensitive as a controller stick, and as a keyboard it wasn’t great either. Hopefully V1 problems, I know they had through another version of the IR keyboard, and then came out with the Hall effect keyboard. I like the idea but never could get used to it, and when the spacebar was loose I retired it after fixing it.

  Yes, the packet passes through routers at each stage and they direct the packet to the ‘closest’ path based on its destination, until the final router has the destination on its network. This can happen a few times (for something in your ISP network), or 10-30+ times for something further away.

  I’m not sure how consistent it is but the static binaries I have for btrfs-progs are about 2x larger than their dynamic counterparts. If you statically compile it only the functions actually used are included in the binary, so it really depends on how much of the library is used.
