I mean, yeah of course they do

Real shame since cortex has a admin TrustZone processor that is licensed to special interests only. For the educational market, this "security" is a selling point. It guarantees that a student isn't running unauthorized code or "cheating" apps. It also likely allows OTA auditing of the classroom's state.

This is substantially inaccurate.

1) Not all ARM Cortex series CPUs have TrustZone. It is absent on many Cortex-M microcontrollers, for example.

2) TrustZone is an operating mode of the CPU, not an "admin processor". Depending on the part, it is often made accessible to developers. (Whether that includes third-party software developers is, of course, up to the device manufacturer.)

For more information, see:

There’s a discussion to be had on the absolutism of technology for decisions or security, and the slow erosion of a certain intangible “discretionary” element in day-to-day life.

Any secure boot design can achieve that, you don't need TrustZone to do that

What prevents a motivated cheater from swapping out the processor entirely?

The effort.

And the cost, and the parents.

Is there any information on exactly what kind of processor is inside this thing? Since running python I'm thinking it's actually a low end mobile processor.

Not if you're rich and own representatives.

When I was working at AWS, which was a new service at the time, the example we often heard was a natural disaster or comet strike; would be what we were making our data centers redundant for. I don't think we were ever considered to be targeted during war and I'm sure they considered that they just didn't want to that affect that morale cost on the staff.

Three availability zones provides no protection against three ballistic missiles.

Region pairs are similarly totally ineffective against a mere six rockets.

No current missile defence system is effective against ballistic warheads reentering from space at hypersonic velocities.

Colocating thousands of businesses and hundreds of government agencies into a handful of hyperscale data centres is the text book definition of putting all of one’s eggs into a single basket.

If Iran’s attacks were more coordinated[1] they would have taken out all zones of every Middle East AWS, Azure, and GCP region. On top of the obvious direct damage to GCC nations it could have very likely permanently damaged the reputations of public clouds, possibly causing trillions in indirect economic damage to the United States.

[1] The theory is that the Iranian regime prepared for decapitation strikes by splitting their military into about thirty cells that can act independently.


> a natural disaster or comet strike

or, that is what they tell you.


Yes, I remember that time, it was back when I wasn't allowed to know anything about what servers were doing other than to look it up in the internal leak, which was never maintained

It's really naïve to think any of the big AI companies won't cheat


Marketing basically. They wanted the console to look more like video equipment and less like a toy. This concern was because of the video game crash of '83


Shouldn't there be a hyper context view model context protocol standard?


Can they liquidate 10% of their AI infra while they're at it?


They’re trying that with meta compute
