People already own them, and have owned them for months or years before the rules were changed for SpaceX.
There's a cost to selling, the brokerage fee plus in many countries there's then taxes due on any profits. Many people would prefer to have unrealized gains where they can pay the tax years ahead, when they need the money.
(Also please don't make the same comment 4+ times.)
My Danish electricity supplier lets me download my smart meter records since 2022.
It's by hour, and the highest times are probably when I was cooking with both the oven and the hob, and perhaps had the washing machine running too. The highest hour used 2.9kWh.
Plenty of cheap (e.g. rental) homes in the UK have crappy electric shows, which are usually rated at 6-8kW — but rarely used for a whole hour.
You'll have no problem getting the Amazon job (or similar) with a masters degree from Cambridge afterwards.
I doubt you'll retire wishing you'd worked just one more year at Amazon.
(I have a masters from Imperial. An equally good alternative if you'd prefer to live in London, or prefer somewhere a little more business focused. Google and Amazon both skipped the first interview stage based on my degree.)
Also if you ask Amazon, they're very likely to keep the job offer open for a year.
China requires showing identification to buy a long-distance train ticket.
Other countries I'm familiar with (Spain, France, Germany, UK, Japan) certainly do let you turn up, buy a ticket, and get on. It will cost more than buying earlier.
The UK also has the third-safest railway in Europe. Some of that will be the result of a safety culture which prevents staff from overriding a door lock.
We were four people, and a car gave us more flexibility for hiking. A couple of times we abandoned plans during the drive once we saw the weather and went elsewhere.
But yes, the buses were good too. The others all used them when they wanted to do something different. (I didn't, as I was the only one willing to drive the car.)
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.
