If the transformer is in the same housing at the plug with a separate cable (as shown): wall wart.
If the DC cable is attached, it's a charger.
If it's housed in its own case, it's a power brick.
If there's no transformer it's a power lead, unless it's rated for over 10A, then it's a power cable.
Dongles are peripherals that are housed in the same casing as the host connector. Anyone who thinks they can power a device with a dongle is a dangerous sociopath.
I'm surprised no-one has mentioned Session yet. Open source, not based on phone numbers, decentralised (uses Tor), based in Switzerland, otherwise it's a lot like Signal. Exactly what you're after, really
Most countries have fixed-rate mortgages. Most rental properties are also mortgaged. So a renter is paying for maintenance/insurance/tax costs, the landlord's profits margin and the landlord's mortgage.
How do you improve this? Easy. You improve it the same way you improve the Sistine Chapel, There Will Come Soft Rains or Nick Offerman's moustache: you leave it the fuck alone.
My two cents (and, no, I've not read the article): things like retractable door handles are fine if they're designed to function completely standalone with no power, etc. Like, having a door handle that's flush with the body looks great and is one less thing to cause noise in a quiet car, but I don't see why it couldn't be completely mechanical and self-contained. The issue is that every little fucking thing has to be motorised and controlled through a touch panel, an app, or some utterly inscrutable "AI" without opt-out.
Look on eBay for USFF PCs. They're mini computers the size of paperback books that are designed for use in large organisations, and they're made by the usual suspects - HP and Dell mostly. Because they get replaced regularly they're cheap but they're just regular desktop PC hardware. A ten year old i5 can handle being a 4K media centre no problem and can be had for €/£/$70.
Yeah, it's hard to overstate what a big deal real-time traffic data was/is. And I have to wonder, how many traffic jams are prevented - or at least reduced - by it. How did we manage before Waze et al.? We were just late a lot more.
