With FBPurity: https://www.fbpurity.com/ I have Facebook on my desktop computer exactly as it used to be in the 2000s when I signed up: content only from my "friends" and a few chosen sources (a band I like etc).
The newsfeed is very slow to load, as to fill the screen the extension must make twenty plus requests while hiding 99% of what Facebook's addiction machine returns.
I've found two bugs myself with Rust coreutils on Ubuntu 26.04, and a breaking change with Rust sudo. I'm disappointed that this was released into the LTS, it really seemed premature.
It's not my field, but at least at my work the network can somehow tell the difference between an authorized user and not. It is not simply using the MAC address.
A guest device connected to the ethernet port in the conference room has the same access as a device connected to the guest wifi, a staff laptop has it's usual access.
In the UK anything "serious" like a train/plane ticket/timetable uses the 24 hour clock. That includes the default way to show a digital clock on a watch, phone or computer.
I live in Denmark, and for such basic words (crisps, trousers, maths, aluminium, football, quid, couldn't care less, fire engine, motorway, petrol, public transport, railway, tram) I use my native British words.
People occasionally comment that it's a British word, but being misunderstood is so unusual I can't remember a recent example. Essentially everyone has read/watched Harry Potter, Dr Who or Midsomer Murders, and Europeans are probably ten times more likely to have visited the UK as the USA.
Assuming the British/American air base remains on some agreement with the Mauritian government, then the Chagos Islands may remain as a special territory of Mauritius, justifying the continual existence of an ISO 3166 code for it.
The Channel Tunnel has security checks because it's a 30km undersea tunnel, and separates an island country with a different approach to weapons to its neighbour. There are no security checks on any other trains in the UK.
It's also not necessary (in Europe) to buy tickets any differently when crossing borders. Advance-purchase tickets are used for long-distance high-speed trains where they don't want people sitting, or wish to spread the demand throughout the day to avoid crowding — that applies whether or not a border is crossed.
I can buy a ticket (paper or electronic) moments before the train from Copenhagen to Malmö leaves, since it's a medium-distance regional train without reserved seating.
It ought to be that reputable retailers in western countries refuse to sell this junk, instead only selling ones they consider secure. Just like they won't sell dangerous toys.
But probably most of these cameras are bought through Amazon, AliExpress or Temu.
Yes, I did exactly this in England 30 or so years ago. It was one of the suggestions in an electronics kit for children, the one with springs to connect the components together.
