I would suspect A pirates book B and tells C about it, C buys book B is a lot more common than A pirates book B and likes it enough to buy it
I have no data to support this, and while I have paid for things I could access for free, but I'm sufficiently pessimistic about human nature to think that's the norm.
The interesting combination rust brings is a memory safe language that can compete with C and C++ for the speed crown.
Its not the cost, its the mass you're trying to reduce. So far, the engineering challenges have made it unfeasible, but its not a surprise that people look at the hundred tons of LOX on a rocket and imagine exchanging it for payload (or aircraft style re-usability).
But SpaceX's brand of rocket development is certainly exciting
> the wing shape adds to the lift in vertical mode
Wings require airspeed to work, which there presumably aren't a lot of in vertical mode.
Of course, those have significantly less performance than the one you put in an airliner or ballistic missile.
As you mention yourself, its a question of good enough. You need to be a lot more accuracy to hit a city after a twenty minute sub-orbital coast, than to find the nearby trench. And yes, computer vision is used to correct for drift.

> a flight control feature the pilots didn't know about
phrasing that made me take issue. To me, it implies that if just the pilots had known about MCAS in detail, the crashes wouldn't have happened, implicitly placing the blame on them. While the reason for both the faulty system and the lack of knowledge can be attributed to Boeing trying to save money, which I think is a more fair target for blame.
Everything else... as the original comment said, is pretty centralized for a decentralized system.
Sure, there would be local copies everywhere, but for a distribution version control system, it's pretty centralized at GitHub
As I understand it, yes the system worked as designed, but the design still managed to kill several hundred people.
I'm not qualified to evaluate the design of the system itself. Was it inherently flawed or would everything have been fine if the optional backup sensor had been mandatory, making this another example of corporate greed causing tragedy?
Either way, I don't think blaming the pilots is fair.
I would love to live in a world where everyone was altruistic and made correct choices for the long term good of society, but I don't. And there are limits to how much I'm willing to act as if I do, when in practice it just means I'm giving away resources to people who are purely (thinkingly or unthinkingly) selfish.
It looks to me like the author of this article has fundamentally misunderstood what a black start is. The fact that some power generation remained both on the peninsula, but also on imported power being available means that to my understanding this cannot be classified as a "black start". A lot of overtime, a lot of careful coordination yes, a black start, no
You could distribute this capacity at each house and feed it back to the grid during peak times. But is TCO of 1000 * 100kWh same price as 100MWh worth of capacity?
If you're going to have the battery anyway(a car) its hard to compete with, but once you need more capacity, I'm not sure it makes sense to distribute it quite as much.
And even if we do want to invest in large amount of grid storage (which we would need to anyway, if we want to transition to renewables), I'm not sure pushing this down to the individual house is sensible. Its a great way to limit economies of scale and make maintenance/inspection harder.
That might have been a worthwhile tradeoff in safety-critical software where failures causes people to die (or not die as the case may be here)
Yes, 2G has fixed time slots, but a slot is used for a lot longer than a single (half?) sample.
You're also making the assumption here that it was a modern Russian system. This wasn't exactly close to the current fighting, its entirely possible this radar was manufactured in the Soviet Union. I don't think those receive a lot (or any) civilian broadcasts.
But for my grandmother, who keeps a little notebook with detailed instructions for how to message people on Facebook? For her this might greatly increase her capabilities.
I was about to write a small essay on how everything from monitors to speeds seemed to be stagnating.
But I actually think there is a chance we might gain two new revolutionary[1]ish ways of interacting with computers within the next decade.
LLMs might truly bring us talking computers. Siri is old, and current AI is a fair mix of real advancement and overhyped, but once the dust settles, I wouldn't be surprised if a significant chunk of the population talks with their computer.
XR devices will likely keep shrinking and I figure somebody will find a killer app for them eventually. 20 years ago, a computer sat on a desk. Today I have one in my pocket. I wouldn't be terribly surprised if in 20 years, I have one in my glasses.
Of course, all of this is speculation. And I don't think the PC is threatened, but it will probably face competition from new ways of using computers.
[1]: As in different and not just slightly better than last years model.
Because the cell network is designed around the towers managing resource allocation, instead of phones trying and hoping nobody else was trying at the same time. Doing it this way increases the total capacity of the network by a lot.
So to create a phone mesh network, you would effectively need to create an entire new protocol stack, probably some enhancements to the frontend/PHY for the initial connection establishment (two phones realizing they're in range of each other) and congestion handling. And depending on how you implemented it, it would be a power hog too, since listening for a tower broadcast requires much less juice than announcing your presence to the world and hoping someone is in range.
(I do actually think there is phone-to-phone communications buried somewhere in the standards, but it still requires the tower for coordination)
But the choice isn't between Apple and not having a phone. Android exists, and as long as its a viable choice, Apple isn't a monopoly.
Cooling might be a challenge. The H100 has a heatsink designed to make use of the case fans. So you need a fairly high airflow through a part which is itself passive.
On a server this isn't too big a problem, you have fans in one end and GPU's blocking the exit on the other end, but in a desktop you probably need to get creative with cardboard/3d printed shrouds to force enough air through it.
And while the article doesn't explicitly say that sails was stowed, it does mention that they were only under sail propulsion once during the trip and that they started the engines to maneuver into the wind. While a (rolling? I don't know the English term) sail is somewhat exposed to the elements even while stowed, its rolled up fairly tight.
In short, I strongly doubt either wet sails or climbing crew contributed in any way to the sinking.
Every successive semiconductor node uses less power than the previous per transistor at the same clock speed. Its just that we then immediately use this headroom to pack more transistors closer and run them faster, so every chip keeps running into power limits, even if they continually do more with said power.
Also, inertia
Every new GPU generation delivers more performance/W than the previous generation (mostly due to semiconductor process improvements) But the competition to have the fastest chip means that total power usage keeps growing.
Power efficient chips just doesn't generate headlines the same way.
And that guarding, probably by thoughts and prayers, aka diddly squat.
