Except that this is a normal thing on wireless networks. A station may roam many times within a few minutes, and due to reflections, may even be in more than one place at a time.

I believe a UE is only ever attached to a single BSSID for a given SSID at a time.

Let me tell you about 2km, directional links and reflections one day, over a beer.

Podcast players like Overcast use push notifications to learn about new episodes of podcasts that should be downloaded in the background. Presumably text-based RSS readers do the same.

Where are the push notifications originating from? Does Overcast have a cloud service that polls the RSS feeds and then sends the notification? I use AntennaPod on Android, and it definitely doesn't do anything like that -- the feed list is stored locally, and the feeds are polled locally.

Yeah, Overcast has a service written in Go that polls RSS feeds and then use iOS push notifications to send new episodes to clients.

My elevator takes almost a minute to go from the first floor to the second floor. I guess I have a slow one.

Nobody without disabilities would use such an elevator.

Connect the dots…

You probably can. I suspect airliner software is appallingly insecure.

Relies very strongly on simple airgapping. Can't do anything to it if there's no wires in the direction you want. Can't remotely hack if there's nothing antenna connected that can talk to flight control. It has the luxury of not needing to do the "limited RCE" that is a modern web request

Reminds me of an episode of Leverage where they wanted to hack into Congress and change the text of a bill. In the show, it turned out everything was airgapped so they had to send a person to drop off a paper copy of the compromised bill. Hmm, that was also a plot line in Better Call Saul.
