The government had consistently argued that the vast majority of schools had already banned mobile phones

Assuming this is true, headline is a no-op. However,

The bill is regarded by many as the biggest piece of child protection legislation in decades and includes proposals for a compulsory register for children who are not in school, a crackdown on profiteering in children's social care, and a "single unique identifier" to help agencies track a child's welfare.

Did you mean for your post to be a reply to this one that mentioned prize drawings? I'm not seeing anything lottery-like in TFA.

I confess the intensity of my own comment was triggered by the other reply throwing shade at variable rate billing in Texas, which you did not actually endorse.

Because you log basically everything, in a reasonably efficient compressed format, in a circular buffer as large as you can afford, in case its useful to figure out WTF happened when a car comes into the shop with some problem. Or figure out which features almost nobody uses so you might remove them in the next iteration. Or figure out what parts wear out too quickly or too slowly, etc.

Better to log it and not need it, than to need it and not have logged it.

A nonsensical, impossible claim - do you really claim the flash memory in the car stores *every* waypoint the car ever travels? It makes no sense, the data retained would be enormous. The linked to article shows four or five data points per second, extrapolate that over the life of the vehicle and you quickly realize it's impossible.

No, that's quite feasible. Assume double precision floating point for latitude and longitude, plus a 64 bit timestamp. 192 bit * 5/s * 10 years comes out to a WHOPPING... 35 GB.

You can log location essentially indefinitely, without using any compression, and without bothering to stop when the car isn't moving, and you never even need to overwrite anything. The most expensive part of the required storage will be getting it certified for automotive ambient temperature.

Atomic clocks, star trackers, inertial navigation with ring laser gyroscopes, compasses augmented with a computer and mostly-up-to-date map of local magnetic fields... GPS is used because it's there and its cheap, not because 2026 tech has no other options.

The main problem with journald's binary logging is how space inefficient it is. The json export is smaller than the on-disk format, even though every message contains the same redundant field labels. They paid the costs of binary-format log storage and the only thing they got in exchange is tamper-evidence which is not as good as forwarding to write-only remote storage. Journald is slightly better for a rare use case (enemy action), but much worse for the typical case (garden variety software bugs and hardware failure), which benefits from verbose logging and long retention.
