There were plans in Japan for wide use of hydrogen as the fuel of the future.

Japanese car manufacturers aligned on that, but weren’t keen on building the necessary infrastructure.

You could lease a hydrogen fuel cell car in CA. There was even a lot of state incentives if you did. But very few fueling stations (iirc, only two in the whole Bay Area)
Old people would do that in my town too and they had to pay for the ticket. I don't see anything wrong with it.

Oil has way more subsidies than renewables. By far

I'm rooting for billionaires to own more and more solar farms please. Let them buy more newspapers and "think-tanks"

Because I'd really like to live on that world where oil has no subsidies, occupies no land and it gets magically transported throught the country
It was awful, but not being exposed to Java, or professional development before I assumed it was how it was meant to be.

I still have to use Java from time to time, and I dislike the amount of "Spring magic" that colleagues try to use with it. No wonder the kids end up writing junk, they are used to never understanding what's going on anyway.

Ammonia is liquid at room temperature under moderate pressure (~10 atm), so that is its usual form for storage and transport.

Ammonia is favored as the refrigerant in industrial cooling systems, but not domestic or automotive for safety reasons.

Ammonia may be burned in ordinary combined-cycle gas turbines and ship engines, requiring only new plumbing, because it corrodes some metals. The ship-building industry is already gearing up for the transition to ammonia fuel. Purely electrical synthesis production capacity will be low through 2026, because factories for synthesizers are still under construction.

The kid tries to beat a piece before it was even placed and then the robot tried to place the piece on his piece while his hands were still covering it. This could have lead to a minor injury even with a human opponent. What is strange is that they insisted on using such a powerful robot arm without any compliance in the actuators.
You are right about the prison, I guess I missed both the word 'planet' and the prison name and filled in the blank, and made an unjust judgement of the author of the video.

'Seems like you watched 5min to just quickly find something to discredit and immediately dismiss it'

That's quite an uncharitable interpretation. You are right about one thing though -- I gave up quite early.

"I see no reason why it couldn't be an "Interesting perspective" or "insightful social commentary""

In the context of judging the American nation as a whole -- of course not.

>desperately want fertility windows to not be a female only thing

But it is a fertility window, and an interesting result most probably didn’t know about, at that. These results can be discussed on their own merits, provided some scientific background.

Politics is such a dead-end dimension through which to have these discussions, but it’s an easy inlet for those who want to voice something, anything, even if it’s a nebulous conspiracy.
I don't think physicist really misinterpret this if you asked them. The problem is, as you say, that the "past" and "future" only have a physical meaning inside your own light cone. As alluded to in the video, you cannot compare space and time differences without defining a common reference frame, so it doesn't really make sense to talk about a past and future in spacelike separated regions of spacetime.

Special relativity is great because it produces some very non-intuitive conclusions about our Universe, and it's always lovely to explore new mind-bending questions arising from these conclusions, especially in outreach pieces like this. I think conceptual discussions like these can be very enlightening, but its not something that keep a lot of physicists up at night.
Calling it a myth doesn’t make it a myth. Power companies have been saying exactly this for years: they need PLANNABLE power generation. Building 3x solar or wind plants means 3x volatility.
To be clear, i definitely agree, the internet is full of crazy people with irrational complaints.

I suppose i consider that part of the price of putting oneself out there. Its hard to imagine getting rid of that without throwing the baby out with the bath water, so to speak.
> It's the other way around, the actual cost of building nuclear instead of much cheaper and faster renewables causes an opportunity cost

That's under the assumption the available money, hardware and labor of ramping up solar and building nuclear plants directly competes with each other. That's a pretty strong assumption and I highly doubt there is a strong enough link between any of those three for your argument to have significant impact.

E.g. We should be able to drive rapid solar expansion with government money and subsidies while incentivcing big energy carriers to build nuclear plants.
OK, here's my amateur take. Most misery is man-made. On the personal scale: envy, unrequited love etc. Also on the macro scale: wars, global warming etc. Perhaps if you create entities with free will they will unavoidably though ignorance or malice do some evil to a lesser to greater extent and therefore cause misery.

Bereavement is unavoidable but many religions promise an afterlife.

Child bone cancer and like are difficult to explain away. Perhaps we would have a cure for cancer if we didn't spend so much effort developing weapons and better advertising algorithms, but that is besides the point. I have heard Muslims believe that Allah will not inflict suffering on someone beyond what they can handle.

God, if they exists, could have created world we everyone were in a state of continually bliss, but what would be a point of that?
Yes. I know the idea of making coffee using lasers is super-cool. I'm just making sure everyone knows how to make cold brew, because it's really nice.
Somewhat related. In the Srimad Bhagvatam Canto 5, a Hindu scripture, it states that the Universe shell (known as the Brahmanda shell) contains all past, present and future events.

It is completely premature to claim that the radioactivity will be "several orders of magnitude less".

The neutron flux produced by a fusion reactor will be much higher than in any fission reactor, and it must be absorbed in a shield, to produce heat, which will be the output of the fission reactor.

Choosing an appropriate material for the shield will minimize the quantity of radioactive material that is created per unit of output energy, but it is pretty certain that the radioactivity will not be "several orders of magnitude less".

The best that can be hoped is that it is possible to find a shield material that will produce only very small quantities of long-lived radioactive isotopes, so that, after a storage for not too many years, the radioactivity might decrease to be "several orders of magnitude less".

Nevertheless this remains to be demonstrated.

For example, any piece of steel present near a fusion reactor would produce copious amounts of cobalt 60, but that would decay to negligible radioactivity after a few hundreds years.

Moreover, to ensure the predicted low residual radioactivity, any shield material needs to be free of impurities, which even in very small quantities could produce dangerous radioactive isotopes.

The requirements for advanced purification will greatly increase the cost of the structural materials for fusion reactors. However this is not a new problem. Similar requirements are imposed on the structural materials for fission reactors, but the fusion reactors will not be any better from this point of view.
The big worry I have about this sort of approach is canvas accessibility. It's something the company also seems to be worried about - they put out a statement a couple of months ago about their plans to address accessibility issues going forward - https://www.figma.com/blog/a-step-forward-in-our-accessibili...
Your reasoning is starting with the wrong premise. As if people are looking for x86 or ARM machines.

I would rather say people are in the market for something to write their thesis on, write some code or do creative work. MacBooks and Windows/Intel laptops can do this both. There is no apples to oranges comparison.

The separation of MacBooks and Windows/Intel laptops based on a chipset or OS is completely arbitrary and opinionated.
The main cost for cheap 2nd hand cars is the fuel in my experience. So you can have a cheap fuel commuter car and a "real" car for trips and towing your boat.

Requires parking for two cars though. But since we are talking about an EV it requires a house anyways since most apartments have no charging.
You are living in it.
I'm not sure I understand any of this, but I'm trying. Can this be summarized as "for any two points in time, one can always find an observer for whom those two points are simultaneous"?
“It found that for women under 35 or over 40, the age of their male partner made little difference to their chances of giving birth. But for women between the ages of 35 and 40, there was a “significant drop” in the live birth rate if the male partner was aged 40 and above.”

Sounds like p-hacking to me.

> It's marked as Known Unknowns, but what is unknown?

The infinite digits of pi that we don't know. But we do know that they exist, so pi, or any other irrational number, will aptly be called a "known unknown."

> Virtually all numbers are irrational.

For every n irrational numbers you name, I can name n+1 rationals. There is no firm basis to the argument that there are somehow more irrational numbers than rational numbers.
This is a classic case of undefined behaviour or memory unsafety. Your mistakes can have an infinitely bad outcome but people blame the programmer even though there are memory safe languages. Yes they sacrifice efficiency but who the fuck wants to consider the billion potential ways of operating a robot in a physically unsafe way?

This means we are going to have the equivalent of GC in robots that interact with other humans.
Tar is definitely very simplistic (and pretty crummy). Things get quite a bit more complicated when you get into the compression side of archiving though. And a lot less fun (I hate bitstreams).
Is it ever not doped though? At what point in the process do they put the smell in?
10 kWh is less than 40 miles / 60 km. It's good enough for grocery shopping but it would be akin to always running with your fuel light on and with 1/20th of the fueling stations (ok you would charge at nighttime). I wouldn't be comfortable with that unless I am going to pay for it half of an equivalent ICE car.
Raises cost, but it is still way below cost of nukes.
Because I usually think about encryption long before I think about compression; the latter's a bit of an afterthought. Ain't the most logical answer in the world, and if I planned from the outset to both compress and encrypt then I'd do it in that order, but compression usually doesn't cross my mind for archival (whereas encryption is pretty much the default for any data I have that's worth archiving).

Literally the same, but probably very different: also in middle of Europe they have recently put me in a prepaid plan with free internet, and I find myself mindlessly scrolling when I have to do other things.

It's easy to not to distract myself when I have to pay for it, but for free it's much harder.

ACCU 2022: Classic Vulnerabilities
I agree. I was friends with a woman who was quite out of my league as a young man. She went on to be a lingerie model for a time, but she was aware of this and would feign flirting with me when we would go out as a group to great effect. A wingwoman beats a wingman every time.
> What does "at scale" mean in this case?

Maybe it means "automatically" (?). It seems like a bad excuse to have a tool automatically output bad CSS. If the CSS is not as good as written by an expert, then there should be a good reason for this like "theoretically impossible to know what the user wants from available specified info in the tool". Otherwise the tool is not doing such a good job.

There have been tools to output CSS forever. The only question is, whether output is appropriate. If it is a mess then it can only be used for fire-and-forget prototypes.

I don't know if any company is exploring what you are mentioning, but battery swapping for electrical scooters (Gogoro) is in common use in Taiwan. Instead of you charge your scooter, you drive to a battery swap station and exchange your empty battery for a full one. see [1].

But some companies are also investigating battery swap stations for cars. So, you might not be able to swap a short-range battery with a long-range battery yourself, but I imagine that would be possible with those battery swap stations. See [2]. Battery swap stations means that you have full range again for the same time it takes to fill a car with gas. But obviously, you need to have enough of those stations to make it usable. And if every car brand is gonna create its own mechanism for battery swapping, then that would probably only be interesting in city areas where it's worthwhile for the manufacturer to run those stations.

Edit: typo.
It's simply not sufficient to have multiple copies. It's way too easy to propagate errors in a way that slips under the radar, which then screws you over 5 years later. The main idea of long-time archival is redundancy. Replication is one form of redundancy, but it's not the only one and not the only one you should use.
No, you need redundancy. Multiple copies isn't sufficient without an appropriate form of data storage. I have no idea why people think a single solution is necessary or sufficient.
Ask HN: Is there any real value in applying ML to process time series data?
Hi,

I work a lot on images processing and extracting insights from it. There seems to be demand for this kind of service.
My university background is closer to time series data, i.e. digital signals processing and modelling, I was wondering if same methods can be applied here. In industrial processes it makes sense to try to model various parts of the process to be able to predict possible fault. This is cool and complicated, and also there are no industrial plants in my environment to go and explore real life data to work with.

The other application of modelling based on time series is within financial markets speculation (forex, stock exchange etc.), though I am not partucularly interested in this area, it appears to me a bit like gambling and as such not something I would like to be involved in.

So I wonder what other use cases for time series modelling are. I have two ideas to build something that may turn out to be useful.

1. I was reading it is possible to find correlations between time series streams, and this could maybe lead to a model that suggests to turn some equipment off because it is not required (based on availability of electrical consumption data)

2. Processing of audio streams and building generative model to create some interesting sound effects (not necessarily music); or the other way around, to detect some events based on sound (i.e. car accident)

Do you know interesting projects that apply machine learning methods to process time series data to do something useful with it? Or maybe you wish a project existed for some particular problem you feel is worth solving?

Prima: Cross-platform GUI toolkit written in Perl
Your (bizarre) original comment was that the whistleblower should be just as worried about Ukraine coming after them. I pointed out the obvious error in this thinking, since Russia is a vicious and vindictive regime with no equal. Now you are talking about something completely different, an equally bizarre anti-Zelensky bugbear. One must question your motivation for making these comments.
Useful context for this is that Anna Patterson started the search engine company Cuil in 02008, four years after writing this article (when she was still at Google). Its results were bad enough that the "Cuil Theory" meme was launched on Reddit and Tumblr making fun of it: https://knowyourmeme.com/memes/sites/cuil-theory:

> One Cuil = One level of abstraction away from the reality of a situation.

> Example: You ask me for a Hamburger.

> 1 Cuil: if you asked me for a hamburger, and I gave you a raccoon.

> 2 Cuils: If you asked me for a hamburger, but it turns out I don't really exist. Where I was originally standing, a picture of a hamburger rests on the ground.

> 3 Cuils: You awake as a hamburger. You start screaming only to have special sauce fly from your lips. The world is in sepia.

> 4 Cuils: Why are we speaking German? A mime cries softly as he cradles a young cow. Your grandfather stares at you as the cow falls apart into patties. You awake only to see me with pickles for eyes, I am singing the song that gives birth to the universe.

http://cuiltheory.wikidot.com/

Two years later, in 02010, the founders shut down the search engine, laid off all the employees, sold its patents to Google, and became Google employees again. Now all that remains of Cuil is the Cuil Theory Wiki.

I'd be really interested to see a retrospective on what went wrong. I guess writing your own search engine really is hard, but I'd like to know what turned out to be so much harder than they expected.

If you're talking about your first comment in this chain(about people refusing to take responsibility), I don't see how that's related to multiculturalism. I've never been to Russia, and I don't even watch Russian media often, but from what I can see, they're trying to promote multiculturalism a lot.

It's not that I don't believe that Russia has a "culture of power" and that people at the top all share the same ideology, but this is happening everywhere.
