I think it's worse than that. Not only does it solve a problem that's already been solved (for those who program with care, at least), but it introduces a whole raft of new problems. Last time I looked (which admittedly was a while ago), nobody could work out how to do a GUI in Rust. If the language experts have trouble working out how to make the language do routine things, adoption is going to be a problem.

Surely they're not so directional that the earth's attenuation is less significant than the sidelobes? The transmitters would need a massive aperture for that to be the case.

I think that's on the receivers, to make sure the answer they give is plausible. With 4 satellites there are actually two solutions in space and time, but one of them will be outside the satellites' orbit and would vary wildly if it's the wrong solution (which it will be for terrestrial users). The satellites don't care (or know) where you are or how fast you're travelling.

About half the constellation should be visible from the moon at any time, so seeing 4 (3 is not enough) satellites should be no issue. And I doubt NASA would be planning on buying an off-the-shelf receiver from Amazon. The biggest issue I can see is that the dilution of precision would be poor because the satellites would all be in pretty much the same direction.

Disappointing when coupled with self-isolation. But familiar to many slashdot readers.

It's many years since I read Ringworld. And I'm not actually in the habit of sneaking up and stealing other people's lettuce.

Apparently, there are bacteria that produce it, and that's what's used for B12 supplements. (It's also in yeasts -- I don't know why they don't use them.)

Vegans don't eat honey, either.

The intelligence is needed to sneak up on the leaf without the owner noticing (or to negotiate access to the leaf with the owner. (Feel free to put "owner" in quotation marks if that fits better with your view of the world.)

Renumbering runways is relatively routine. Magnetic North has always drifted - I recall Heathrow's being renumbered in - er, was it the late 70s? - though as they're rounded to the nearest ten degrees there's plenty of time for the paint to dry.

But it answers the headline question of whether we would trust it -- millions do, every day.

Have you seen the state of Stonehenge?

"I refuse to spend my life worrying about what I eat. There is no pleasure worth forgoing just for an extra three years in the geriatric ward."

In effect, yes. If the person doesn't make minimum wage, the difference is effectively deducted from their tips. And it was going on in the UK too, but there was an outcry about it when it became public knowledge. Just because something has been going on for ages doesn't mean it's right, especially if the victims are those who don't have much power or influence.

It presumably is in the USA, which is how Amazon get away with this. It isn't in places such as the UK, where that practice would be illegal. After all, the supposed reason for tipping is to get better service; how would that work if the person providing the service doesn't get the tip?
