You can but the track has to be built for it. Japan has stations that are passed at 320km/h (200mph). You need minimum four tracks (two platforms, two passing) and curves/gradients suitable for the speed, along with noise mitigations as necessary.

If you’re trying to re-use tracks and stations built in the 1800s that’s possibly less feasible.

Part of handling that is having both local and limited-stop services (which they likely already do) and a good local/commuter train network.

Commercial planes often take off in mild tailwinds; they’re typically certified for 10-15kt of tailwind. It’s sometimes easier for the airport than re-sequencing all the flights especially if it’s only a mild tailwind.

Florence has hills to one side (the west?) that mean taking off in that direction also carries a performance penalty because you need good engine-out climb rates. So it can be a choice of tailwind or hills.

It’s all statistics. If you’re never getting surprised by the weather, you are probably leaving money on the table. If it’s happening all the time, you’re selling too many seats.

It will also depend on how far out the last seat was sold.

I don’t think there’s much if any airfreight going through LCA. Both Florence and LCA are very short constrained runways, near much larger airports where you can more easily deal with freight.

Usually freight gets offloaded first, but then you’re looking at passengers and bags. Or an enroute fuel stop somewhere with a longer runway.

It’s often not just the heat, but also wind direction both at the airport and enroute. They probably plan for some combination of the three, but not worse case on all at once.

Headwinds on takeoff mean you can takeoff with more mass. Tailwinds, crosswinds, and higher temperatures mean you can carry less mass.

Tailwinds enroute mean you get a higher groundspeed for a given airspeed and arrive earlier, having burnt less fuel. If the tailwinds are known before departure, you can carry less fuel (less mass) and thus more payload (passengers).

There is nothing you can do to ‘prepare’ other than sell fewer tickets (and thus leave the flight unnecessarily empty on days when there isn’t adverse weather) or use a bigger plane that still needs to be lightly loaded.

I meant to write FPU. It got auto-mangled and I thought I corrected it; clearly not…

I thought Intel already managed that with the GPU issues.

ToS is effectively a contract.

This interpretation of the ToS could be deemed unconscionable, but that seems like the kind of argument that takes a judge and 5-6 figures in legal fees to settle.

An arbitrator is just going to read it, say ‘yup, you broke the rule’, and side with the company.

I would hope so. CFRA seems to be the only explicit protection.

If it was just plain old trademark/copyright law, you’d be right.

It sounds like Tesla are basically saying that you signed an NDA/non-disparagement clause when you bought the vehicle, and therefore it’s a contract dispute.

Doh.

If you mean the bar, then even stainless of that size is going to be very low resistance - milliohms?

If you mean the body, then I believe it gets complicated. Skin resistance will be diminished by the piercings having a relatively large contact area and probably being somewhat sweat covered - I’m not sure exactly what the ‘skin’ inside the piercing tunnel is like. Certainly you can feel current from a 9V across the wet inner-body skin of your tongue.

The internal path will be quite low resistance because the inside of the body is a sack full of salty water.

It wouldn’t be fatal, even across the chest, but it could hurt.

Wouldn’t expect the bar itself to get hot; just the battery. The bar will be very low resistance and therefore only a tiny portion of the total heat will end up in it.

Now, if you stuck one terminal to one piercing and another terminal to another piercing, then you might have a bad time…

Yeah, I’m always a little skeptical about the ‘feel it’ claims. But computers don’t have to adapt to progressive wear; I’m sure you could configure the ABS/traction control to indicate that in dry conditions consistently slipping below say 0.3g (number pulled out of ass) of applied traction implies an excessively worn tire.

Once you get below a certain level of performance, all the braking/steering assumptions involved in self driving start breaking down too.

Airliner engines are getting to ludicrous reliability numbers (the latest generation appears to be closing in on 10M hours between inflight shutdowns) largely through predictive maintenance performed far in advance. We’re well past ‘most pilots never see an engine failure’ and approaching ‘most airlines don’t see an engine failure’.

And there are few locations more abusive to sensors than the hot section of a turbine engine.

And yet people can feel the difference between a worn tire and a new tire. Accelerometers and the torque feedback on the motor drives (both of which are already widespread in cars out of necessity for other equipment) can feel when the tires are on the edge of losing traction.

One of the changes in automation over the last decade or two is a move away from having many specific ‘sensor for monitoring X’, towards interpreting a smaller number of better sensors in novel ways to provide the same data.

That seems relatively easy (and cars already have it with the little bit of metal that makes the brakes squeal when worn):

From the sensor being triggered, you have say 1-2000km to get the sensor or brake pad (whatever the issue is) fixed.

I somewhat disagree with this. If you can feel worn tires, brakes, or suspension bushings, it’s easy to imagine the car feeling them and raising a service alert, and locking out if not appropriately serviced.

Vendor lock-in and enshittification, baby.

Also:

Thin stamped construction is cheap, but can still be fitted with sleeving on the live (active and neutral) pins like UK & europlug, but not US plugs. This prevents objects or fingers getting to live pins on a partially inserted plug.

Industry has agreed that leads exit either straight out, or down-and-right, so there is no conflict for horizontal or vertical sockets. Sockets are universally installed earth-down.

Reasonably compact.

I found opensuse’s default firewall rules were very restrictive and you needed to open a port.
