There’s probably a bunch of permissions errors, filesystems warnings for cross-filesystem mounts or links, etc. all going to stderr. Linux output streams are a bit odd, 1 is stdout and 2 is stderr. So the command is redirecting the “noise” to null and just printing the actual command output. That would be my assessment, but OP could probably give a more correct answer..!

    Aren’t loads of embedded devices still using the old school edge network? Like car remote systems, electric meters, weather stations, etc?

    Miata is always the answer! They’re cheap, fun, simple, and very rewarding. Parts are super common, and there are plenty of neat upgrades you can tinker with when nothing’s wrong with it ;)

    Don’t our bills have to go through a legal review process? The charter is pretty clear on stuff like this… It’s pretty obvious this is dead in the water whether our MPs like it or not. But they’ll keep trying until they get what they want.

    A very effective first step is to put it on a vhost with a domain you control, and drop traffic to the default vhost. 99.999% of scanners are just going through IPs looking for stuff, so don’t give them anything. Better yet, block any IP that scans you more than a dozen or so times.

    Obviously some stuff will find you through cert issuance logs, but most of the bastards don’t bother with that level of sophistication.

    I’m not an expert, but I think it has to do with AC vs DC electrification. With a DC third rail subway you can just feed it back into the lines no problem, but with AC you have to get the phase sync exactly correct or it will cause pretty serious problems. It’s the kind of thing that depends a lot on how old the system is, how energy distribution works, etc.

    If there is an actual expert here I’d also like to know more..!

    Something interesting about locomotives is that they do quite a bit of braking by using the motors as generators, but it’s NOT regenerative braking! There’s basically no electrical storage system that can handle that amount of energy that quickly, all batteries available today can NOT handle that kind of power surge safely. Some catenary systems can handle back-feeding, and it’s becoming more common, but it’s not something a diesel-electric can do. Instead they have massive resistors and radiators at the top of the locomotive and they bleed it off as heat. It’s less wear on the brake pads, so it’s often preferred when they don’t need to stop quickly.
