It's ability to hover, and fixing itself to the deck allows for a much expanded launch envelope.

How so? I don't see how hovering makes any difference at all... it's just a waste of fuel, increasing gravity loss. It's nicer from a controllability standpoint, but SpaceX has clearly perfected the hoverslam maneuver and once you have that down it makes more sense than to waste fuel hovering and translating. Bolting itself into the deck helps with rough seas, I suppose, but it seems unlikely you'd want to try landing in very rough conditions anyway.

Spacex doesn't seem to care for doing this all that often any more.

Nah. They do it when it makes sense. They don't do it for Starlink launches because it's cheaper to launch a slightly lighter load and shorten turnaround time, to avoid waiting for the droneship to ferry the rocket back to land. Plus their launch cadence is so high that they'd need a big fleet of droneships. So they reserve those for paying customers who need the greater capacity. I don't think anything about New Glenn's capabilities changes those calculations.

The AI is significantly more aware of other cars around it. Unlike a human, the self-driving system has continuous 360-degree visibility.

While I agree that it *should* always be safe to hit the brakes, the truth is that when you're driving on busy roads most of the time it's not safe to brake hard. People follow too close more often than they maintain proper separation.

I also agree that drivers should always have sufficient situational awareness to know whether or not it's safe to brake, they often don't, and they often react without considering the consequences. This isn't a "man vs woman" thing, it's a human thing.

it is a royal BITCH to try and remove them

It's worth noting that the way you remove them is by making them stop just sitting there, to the degree they do. The various approaches ultimately just try to break the ink up into smaller pieces that can be absorbed into the bloodstream and carried throughout the body... hopefully to get filtered out by the kidneys and liver and then excreted, but who knows? It seems likely to me that tattoo removal may create exactly the same effects as tattoo application, but moreso.

You shouldn't worry about getting rear ended. That's the worry of the person behind you. It's their fault if you get rear ended.

Have you ever been rear-ended? I have, twice. Both times while I was stopped at a red light, so fault was absolutely incontestable. It's their fault, but you end up without a car. Sure, their insurance has to pay, but they only have to give you what it's worth, not what it will cost you to replace it, and the difference is significant. Not to mention that you could be injured. Your hospital bills will be covered, but you were still injured and have to deal with pain, the recovery, and maybe even some amount of permanent damage. My neck has never been quite right after the second time I was rear-ended.

I can tell you exsctly how many human drivers would respond in a situation like this, because I've seen it happen and have heard about it enough times: the driver would have accelerated away from the incident at high speed.

They would have done that after slamming on the brakes in a vain attempt to avoid hitting the dog, possibly losing control of their vehicle, and possibly causing a collision with other cars or objects. If their reaction failed to cause a serious accident, then maybe they'd have sped away.

Many millions of those miles are on roads that never have animals on them.

Until last month, Waymo only allowed their cars to drive on city streets, no freeway driving. Even now, freeway usage is limited, only for selected riders (I'm not sure what the selection criteria is).

So, basically all of Waymo's millions of miles are on streets that often have animals on them.

if it were a medical study on, for example, a robotic surgical system with 10% of the mortality rate of a human surgeon, there would still be concern if, every now and then the system removed a patient's appendix at random during heart surgery.

Sure, there would be concern, but unless you're dumb you will still pick the option with the 90% lower mortality/harm rate. Yeah, it's good to investigate and fix the problem (assuming fixing the problem doesn't increase the mortality rate), but you should still use the provably better option.

The real question is if it simply failed to notice the dog or if it noticed the dog and didn't even attempt to stop.

Also, why it didn't attempt to stop (if it didn't). If it didn't attempt to stop because it correctly determined that attempting to stop would risk causing a more serious accident with other vehicles on the road, that's not only good, it's better than the vast majority of human drivers.

Comment Re:Europe has itself to blame for this (Score 3, Insightful) 264

Eastern Europe was screaming about how dangerous this was, but they weren't listened to.

One of the most insane things is how after Russia's surprisingly poor military performance in the Georgian war, the Merkel government was disturbed not that Russia invaded Georgia, but at the level of disarray in the Russian army, and sought a deliberate policy of improving the Russian military. They perceived Russia as a bulkwark against e.g. Islamic extremism, and as a potential strategic partner. They supported for example Rheinmetal building a modern training facility in Russia and sent trainers to work with the Russian military.

With Georgia I could understand (though adamantly disagreed) how some dismissed it as a "local conflict" because it could be spun as "Georgia attacking an innocent separatist state and Russia just keeping their alliances". But after 2014 there was no viable spin that could disguise Russia's imperial project. Yet so many kept sticking their fingers in their years going, "LA LA LA, I CAN'T HEAR YOU!" and pretending like we could keep living as we were before. It was delusional and maddening.

The EU has three times Russia's population and an order of magnitude larger of an economy. In any normal world, Russia should be terrified of angering Europe, not the other way around. But our petty differences, our shortsightedness, our adamant refusal to believe deterrence is needed, much less to pay to actually deter or even understand what that means... we set ourselves up for this.

And I say this to in no way excuse the US's behavior. The US was doing the same thing as us (distance just rendered Russia less of a US trading partner) and every single president wanted to do a "reset" of relations with Russia, which Russia repeatedly used to weaken western defenses in Europe. And it's one thing for the US to say to Europe "You need to pay more for defense" (which is unarguable), even to set realistic deadlines for getting defense spending up, but it's an entirely different thing to just come in and abandon an ally right in the middle of their deepest security crisis since World War II. It's hard to describe to Americans how betrayed most Europeans feel at America right now. The US organized and built the world order it desired (even the formation of the EU was strongly promoted by the US), and then just ripped it out from under our feet when it we're under attack.

A friend once described Europe in the past decades as having been "a kept woman" to America. And indeed, life can be comfortable as a kept woman, and both sides can benefit. America built bases all over Europe to project global power; got access to European militaries for their endeavours, got reliable European military supply chains, etc and yet remained firmly in control of NATO policy; maintained itself as the world's reserve currency; were in a position that Europe could never stop them from doing things Europeans disliked (for example, from invading Iraq); and on and on - while Europe decided that letting the US dominate was worth being able to focus on ourselves. But a kept woman has no real freedom, no real security, and your entire life can come crashing down if you cross them or they no longer want you.

Submission + - Be nice - Batman is watching! (sciencealert.com)

Black Parrot writes: From ScienceAlert:

A new study has found that people are more likely to act kind towards others when Batman is present â" and not for the reasons you might assume.
[...]
Psychologists from the Catholic University of the Sacred Heart in Italy conducted experiments on the Milan metro to see who, if anyone, might offer their seat to a pregnant passenger.
The kicker? Sometimes Batman was there â" or at least, another experimenter dressed as him. The researchers were checking if people were more likely to give up their seat in the presence of the caped crusader.
And sure enough, there did seem to be a correlation. In 138 different experiments, somebody offered their seat to an experimenter wearing a hidden prosthetic belly 67.21 percent of the time in the presence of Batman.
That's a lot more often than times the superhero wasn't around â" in those cases, a passenger offered a seat just 37.66 percent of the time.
[...]
"Interestingly, among those who left their spot in the experimental condition, nobody directly associated their gesture with the presence of Batman, and 14 (43.75 percent) reported that they did not see Batman at all."

The article goes on to speculate about what is causing people to be more generous.

They clearly didn't even use a proper image generator - that's clearly the old crappy ChatGPT-builtin image generator. It's not like it's a useful figure with a few errors - the entire thing is sheer nonsense - the more you look at it, the worse it gets. And this is Figure 1 in a *paper in Nature*. Just insane.

This problem will decrease with time (here are two infographics from Gemini 3 I made just by pasting in an entire very long thread on Bluesky and asking for infographics, with only a few minor bits of touchup). Gemini successfully condensed a really huge amount of information into infographics, and the only sorts of "errors" were things like, I didn't like the title, a character or two was slightly misshapen, etc. It's to the point that you could paste in entire papers and datasets and get actually useful graphics out, in a nearly-finished or even completely-finished state. But no matter how good the models get, you'll always *have* to look at what you generate to see if it's (A) right, and (B) actually what you wanted.
