- in normal mode (Full Supervision) the driver's actions are monitored and unsafe operations lead to an emergency brake
- but there is a fully manual mode (Staff Responsible) which does exactly that - the driver is fully responsible for what they do. If they get bad instructions from the control center, no technical barrier against crashes exist.
Older systems like LZB usually are even more permissible.
- trains go in tunnels or tracks are between houses. When train control systems were defined in the 1990's, there was no way to make them sensitive enough to record GPS positions. Instead there is a different location system based on so-called balises with a fixed position on the tracks. Every time a train crosses one, it knows where it is.
- Planes go in 3 dimensions, trains in one. If ATC wants to ensure two planes do not collide, they will assign them different headings and/or heights. Precise position isn't that important. Trains cannot avoid each other, that's why they move in blocks.
And yes, they do signal their position back to the control center, it's just a different protocol
That's where the EU came in and developed ETCS (https://en.wikipedia.org/wiki/European_Train_Control_System) as a modern alternative. Unfortunately, the EU doesn't have the legislative power to force member states to adopt it and also not the money to bribe them. So ETCS is still competing with the legacy systems.
However, the reason for that crash apparently was the dispatcher who greenlit the cab driver to go full speed ahead after the train control system on that track had crashed even though they knew that another train was reporting that it was unable to restart and get going. Procedures in case of a train control outage are clear: all trains can only move at a max speed of 40Km/h - slow enough to drive and brake on sight.
Instead, that train crashed into the stationary one coming from 200Km/h
Wait, I thought Spain's high-speed rail network was all ETCS L1 or even L2?
But well, they'll survive :) Their M-series was a stroke of luck considering AI.
But in principle you are right, the 7y is too restrictive.
However, whether you really notice a difference reading on the thing I kinda doubt.
If I had to venture a guess it would be that this is the last stand for hackers that are able to root all kinds of older devices, but companies like Apple will shell out the money to prevent this for their next-gen devices.
It's likely that low-cost device makers will not do that, so maybe rooting will still persist for cheap stuff.
I am personally not always happy with the gestures, but some can be disabled. I don't have much use for my iPad apart from watching some videos, for everything that requires concentration, I will fallback to my laptop. I still think it is a marvelous machine how the hardware and iPadOS play together.
That doesn't make a lot of sense. 50hr/w was the norm in many countries till the 1960's or so, and yet people were having lots of babies indicating having marriages with sex.
That's a complete non-starter for now and the next decades. Fully automated operation for 1-dimensional transport (trains) is a solved issue, for 2D, not so much and most certainly not for 3D.
Even though modern planes are very reliable, too many things can go wrong during flight to leave it to a machine - and for what? Just for bragging rights?
I would go with the original, Apple or the Win11 one. Material would be good, what's with the lavender shades?
I always try to reduce the palette: say two background shades max, no drop shadows, only as many foreground colors as needed and if it seems to bland, add more bells and whistles.
It was a mistake to shut down the working nuclear power plants, and that also coincided with the abrupt loss of all (cheap) gas from Russia. Now, the country imports expensive LNG and renewables generate something like 80% on a good day - but thanks to merit order, the most expensive form of power generation sets the price and that is gas.
It doesn't help that thanks to shifts in industry, the grid has to be re-developed north->south instead of west->east and south-north. NIMBYism is rampant in Germany, so new high-voltage lines can take decades. Meanwhile, renewable capacity has to be shutdown if the transmission capacity of the grid cannot keep up during windy, sunny days.
Things are slowly improving what with grid-scale batteries coming online, and one major north-south connection being done. But yeah, it's going to take years still, and if our current governing coalition have their say, it's going to take even longer.
Also: "it shouldn't be here; the nearest coastline is Dammam's, 500 km away." - are people really that ignorant about plate tectonics and sea fossils in mountains?
That's not even true, it was Merkel's administration. Under Schröder, the plan for the phase-out was formulated and set in motion, only to be stopped and then restarted by Merkel.
The modern anti-nuclear movement in Germany got started in the 1970's by the TMI accident and a book named "Der Atom-Staat". Chornobyl of course put the nails into the coffin.
However, if you wait till your competition goes broke, you need to ensure you survive long enough and stay big enough so you don't get bought. That's not exactly easy.
They (Apple) bought out intel's wireless modems and are using them instead of Qualcomm's chips. IIRC, they aren't the best in class when it comes to raw throughput, but quite good in terms of throughput vs power consumption.
