Yes, and they wear out and must be replaced. The drive train is powering an electric motor. Toyota might be expecting to get more service work out of fuel cells than batteries. Just throwing things at the wall for their motives though.
Other people’s kids can be dull. I can empathize with that...

But my own kid, despite statistically being just like all the kids and could be considered just as dull, is most certainly not dull to me.
They're technically wrong as energy density is per volume, "specific energy" or "massic energy" is per mass.

Also while the specific energy of hydrogen is good, you have to account for the weight of the container. You can store fuel in a bucket, not so hydrogen.
And Australians... and Canadians say soccer.
I tend to agree - if Toyota wants to develop in hydrogen, why should it matter? And by the way li-on isn’t something you just walk down to Walgreens, buy a palette of a123 batteries and put them in your car. It’s a significant supply chain hurdle that Tesla still has a non trivial cost containment issue despite having a gigafactory or two, giving them an advantage over other manufacturers who don’t have access to the supply chain the way Tesla does. If you look at ev production at scale with numerous parties with at scale products, it’s unlikely that this picture is complete without a significant presence in China. So there you have the real reason why Toyota’s strategy makes sense... what if in ten years, you can’t buy the lithium to make your own batteries? What if you can’t even buy an assembled battery? What if you have to buy the entire vehicle from China to be in the ev space? Not convinced? I present to you as evidence, Tesla gigafactory 3... you guys might want to start thinking about Toyota’s point of view.
No, I'm not thinking of

dec1 = hex1.toDecimal();

because

num1 = 0xff00 + 64;

works just as well and so does

functionThatExpectsNumber(0b1101);

as does

p1 = mat1 * vec1;

Lengths are just as absolute as integers, but we have different ways to input and represent them. A sufficiently advanced language understands the equivalences and does just the right thing. Adding apples and oranges does not happen.

Generally your function should not expect inches, it should expect some length and I can input it in any unit of length I want.

Sure there are cases where you're constrained and need to account for the limited range and precision of your underlying storage format, but that should not be the default for any modern high level general purpose programming language. We don't need to concern ourselves with grade school stuff, the computer can do it for us.

Adding apples to oranges is concern at a lower level than the abstraction we should be working with by default. Doing arithmetic by hand on pen and paper is pretty low level.

Adding apples to oranges is also a concern when you don't have proper types by which the system can deduce that orange is actually just 2.54*apple.
What exactly indicates that The Outer Worlds has really bad code design?
tl;dr: there are people starting conversations with accounts that clearly seem to be childrens' on Instagram, sending unsolicited and very sexually explicit content, and basically openly requesting CP.

This is serious and naturally the extreme proposed solutions are all flawed, yet we as a society ought to spend more energy managing and ultimately solving this. (Education of kids about exploitation, better tech solutions to prevent these messages reaching them - reputation systems on social media sites - for establishing contactability for both senders and recipients. Long term probably some serious genetic engineering to make consentability a must for sexual attraction, and whatever out of the box ideas are out there.)
How McKinsey Makes Its Own Rules
The metaphysics are unimportant. The important question as far as AGI is concerned is whether human intelligence is physically computable. And quantum computation is less powerful than non deterministic Turing computation. So, we can bound quantum computation with NTMs.
If the one ordered to do the killing knows the target is the one ordering the kill and the target is of a sound mind, I would call it assisted suicide (https://en.wikipedia.org/wiki/Assisted_death), and I wouldn’t call what the killer did murder.
To paraphrase Jordan Peterson:

"No one ever walked into my psychology practice because their parents made them too emotionally independent."

There are some parents out there who continually martyr themselves because they think it makes them a good person (I get 4 hours of sleep a night to make sure my kids have everything! I'm awesome!) but are in fact overinvolved and setting a bad example for the kid by not taking care of themselves. Anecdotally I've found most of my married friends who are/were hesitant about kids were raised by such parents.

It's healthy for the kid to see that the parent needs some enforced level of time to themselves, short of neglect of course. The precise balance is up to the individual.
Agree. In many ways I wonder if we're seeing a couple compounding forces at play:

* The introduction of birth control and giving people (yes both men and women) too much control over procreation without having to control the impulse for procreation.

* Seeing people solely as material beings as a consequence of the Enlightenment. After all, if you're just the matter you're composed off then you're no more special than a rock or your iPhone or a dog. Why sacrifice so much material comfort in exchange for the material discomfort that parenting will inevitably cause if the baby is just matter?
The prisoners hired ostensibly showed commitment to good behavior, rehabilitation, and self-education, over a period of many years, in an environment extremely non-conducive to such aspirations. That amounts to more than “zero”.
Just browsed google maps. By my count there are more public EV chargers in a mile radius of my house (east bay) than hydrogen fuel stations in San Francisco, San Mateo, Contra Costa, and Alameda counties combined.

It appears that even among early adopters of new energy sources, the market has spoken.
Yeah, does that not seem odd? Sure seems like a very suspicious coincidence.

Whatever is doing that to you is a blessing, I suspect, because there are parents out there who do not have that. What must their lives be like?

Or, you know, they enjoy the craft/art-form, and want to do it professionally. There's definitely some weird selection pressure in show-biz, and impulsiveness/ego may play a small role, but there's a million ego-maniacs for every Tom Cruise.
Yeah, "what about HP expensive offerings". Of course they're overpriced too. HP, Dell and likes demand ridiculous premiums on the front so they can build respect and offer "discounts" later in the back. You can see the real value after 4-5 years when you can find their boxes on ebay for peanuts.

Apple on the other hand is a master of price hiking behind smoke and mirrors. The target group of this product seem to be gullible easy spenders. Which is not a small group, and maybe containing some big rich companies that do not care for price, so profit-wise, it makes sense for Apple to price the weakest config for $6000. People or small businesses that care about value/money will go with buying/building their own Xeon machine, or go with the EPYC/Threadripper platform with its tradeoffs, in both cases with much higher performance. For half the price at most.
Imposing constraints forces people to be more creative in their approach. This seems like it was explicitly a goal of the challenge, to find more clever ways to solve problems without just relying on more data.

They're just biasing competitors towards efficient solutions.
As a desert dweller, I prefer a drive train that outputs water just in principle. We need water out here, it’s only getting more dry, and there will be no big project coming to pipe water inland. Buuuut, batteries and electricity are here today.

Not exactly, but my take was similar, that he seemed to be implying that it doesn't make you a "worse" parent.

It's a weird thing to somehow think that an AI with only 4 days of training data should somehow outperform even a human child, which has a decade or more of imitation learning experience. A human doesn't come to minecraft "knowing nothing", like the machine learning programs in this challenge. They already know basically everything there is to know in order to perform task-oriented goal planning and only need to focus on task discovery.

If anyone had pass the bar this challenge set, they'd have basically solved the biggest hurdle in general AI, and would probably have received a call from John Carmack.
Never mistake feeling with wanting. This is such a great mistake.

Mining and processing Lithium isn't that clean either.
If you (or anyone reading this) can link to any examples of or details about this sort of thing I'd be interested in seeing it.

Don't get me wrong - I believe you - I'm just curious about it and would like to learn more.
Hard pass then.
It’s perfectly feasible to capture carbon from a natural gas refinery producing liquid H2 and sequester it safely. Doing that safely and consistently is going to be an engineering challenge, but so are the advances in battery technology and the need to scale lithium production in clean, safe ways that batteries would require. If anyone’s done the work on which approach is better, I’d be interested to see it.
I don’t think this would work very well on the Oculus Rift S. I’ve tried using BigScreen to navigate webpages and it’s just not that easy to read normal sized text. Maybe it’s better on the Valve Index?

I find that very unlikely in this situation.
Using Matplotlib with Scala on Notebook (and More)
Well he started off working on super capacitors I think in college. Or he said he wanted to, I forget. More recently, Tesla has purchased a super capacitor company (Maxwell). I’m using some supercapacitors in a project at work. For $500 we get a super capacitor with the capacity of a $12 battery. For the time being, batteries are way, way ahead on cost.

And yet if you look at some of the highest achieving people, many of them have kids. Presidents have kids. CEOs have kids. Billionaires and movie stars have kids. Nobel prize winners have kids. Not all of them, but many. A key part is probably having a spouse who is willing to do a larger share of the childcare, but kids do not seem to be a disqualifying factor for achieving just about anything.
Hydrogen electrolysys can't be done efficiently at home. And the efficiency even in industrial plants is pretty bad, about 50% to produce hydrogen compressed for car use, and that doesn't include the fuel cell efficiency that brings the total efficiency to about 30%.
Batteries have much better efficiency.
Have you considered using localStorage? It’s not sent across the wire (I’m sure you know), and as described you’re counting sessions not unique users.
PyPI Is Down
Currently the best electrolysis can do is 50kWh/kg of hydrogen, which is about equivalent to a gallon of gas. That's 7c/kWh to match a $3.6 gallon (as found in CA or HI). And that's before the storage issue is even considered.
Uber and Lyft Suggest the Days of Cheap Rides Could Be Over
First Light Fusion, Commonwealth Fusion Systems, and Tokamak Energy are all aiming at net energy by 2025 and grid-connected power by 2030. Lockheed Martin wants power plants at scale in the 2020s, with designs small enough to power aircraft (though their approach is more novel than CFS/TE physically). All four of companies have cost-effective designs radically more economically feasible than the JET/ITER/DEMO pathway of old.

There's no magic to fusion, it's just a matter of finding a way to do it economically.

Meanwhile, there are other 40+ programmers like myself who still enjoy themselves with the latest tech, fads, open offices, lots of communication and fellow young programmers.

Programming nowadays has improved so much it's crazy.

- Have a problem? 99% chance your answer is on StackOverflow. (anyone remember the days before internet? I do! Searching (alone) hours on some cryptic error message)

- Programming robots is so easy and cheap nowadays.

- Everyone walks around with a super powerful computer, integrated GPU, camera, GPS, gyroscope and internet ready wherever you go.

- So much powerful stuff available for free.

- Current IDE's have so much handy functionality.

- Make your software available to the world in an instant. Want to run your own server software? So easy and cheap!

So yeah, grumpy old programmers still exist. But I also know plenty of old programmers who love all the new stuff.
But BEV cannot really use intermittent energy sources. Not without severely inconveniencing drivers and that's impossible. Hydrogen could be made from intermittent energy sources.
The way I explain it to my non-dads male coworkers, 1 to 18 months is mommy time and you’re there to help, but month 19 and forward is all daddy time until they’re 15 and they hate you. You’re literally the coolest person on earth for them. I like being a superhero.
Good. I'm not convinced that a unipolar world is a good thing. As long as open war does not occur, some national rivalry stimulates innovation just as corporate competition does. A unipolar world is like a stagnant monopoly in the business sphere. Politically you can see the effect in any one party US state (regardless of party). The party in power gets corrupt and incompetent.

Maybe China vs USA will put humanity on Mars.
The documentation [1] has details. For input they get an RGB image (i.e. what a player would see on the screen, minus the UI) and other relevant information (e.g. inventory). For output they have to specify from a list of possible actions that they can take: move forward, move back, craft an item, etc.

The principle is cute, but on a regional environmental level the water emitted won’t make a difference.

And batteries are here already. Buy a Tesla.
Also, some parents do develop those feelings, but over time rather than immediately.
Out of curiosity, how old are you? I was much more selfish and 'go go go' in my 20s. In my mid thirties now and mellowed a lot. I find parenting a joy now, but think I would have hated it 10 years ago.
>It's up to each person to make the effort to grow their understanding, which requires study and self-development.

That's true, but it's falling into the same problem I was trying to tease out of GP, which is whether an argument can be produced that study and self-development will lead to one appreciating Bach over Harry Potter. We say that spherical earth theories are superior to flat earth ones not because individuals applied study and self-development to their opinions, but because the spherical earth theory is objectively true, it conforms to the generally agreed upon epistemology. The same can't be said about art (as far as I can tell).

Is Bach "better" than Harry Potter because an individual who studies and self-develops will judge it to be so, or do those who study and self-develop judge it to be so because it's objectively better?

Even then, let's take the individuals out of the equation. To a person unacquainted with both Harry Potter and Bach, on what grounds does an aesthetician say that we should assign higher value to Bach?
that can be achieved by other means though, through other's children or via longevity
Coping with Flexbox
I have kids and what I’ve learned and noticed is that kids are, unsurprisingly, just like people, and there are selfish ones, and not so selfish ones. Generalizations don’t really work with people, or kids, because kids are people.
Our biology is what survived billions of years of culling out beings with insufficient skill or will to live.
Most people's ambitions were created for them and all ambitions live in the context of our lived experiences.

Imagine that one adjusts as one's life is adjusting around them. Surprise?

You discover if you had really seen the possibility space of life and weighed it's options.
I regret reading this essay because now the discouragement is back. I have wanted children; my wife has not. I am determined not to force the issue as she would be the one undertaking most of the burden, and why should I cause her to resent me? So I made peace with it, but every time something like this comes up I am torn again.
That's not the Toyota way. From a Westrum "Three Cultures Model" perspective Toyota would fall into the Generative classification, not Pathological or Bureaucratic.

Based on the discussion in the article I think Toyota is saying they've learned EVs are not scalable and are not a solution to all customer needs Toyota currently services. They're betting hydrogen is the solution.
Just be careful. Kubeflow is heading toward GCP only features (for example, they are dropping cert-manager), while you are betting on AWS.
Ask HN: What is your favorite desk?
I don't know if this is what was implied - but my wife and I have always believed strongly that you have to maintain the "hub" that is your relationship in order for the bigger picture - the family - to thrive.

My kids (now 12 and 15, goddamit!) are 100% the entirety of my life: the beginning, middle and end. They're the reason my wife and I work for ourselves, the reason we don't work all the time, the reason we haven't grown our business even though we could have. We want to be here for them in the tiny period of time we have them at home, and who cares if we end up financially poorer because of it - our lives are infinitely richer with this time we have as a family together.

But.

Some parents become parents and let their kids dominate. And I don't mean in a disciplinary way, I mean that the kids - especially when tiny - take over the adults lives too. This was obvious for us in the parents that let their kids stay up until whatever time, had no routine, let their kids sleep in their bed, never got out as a couple, etc etc.

The point I'm making is that having kids is THE single hardest thing you'll ever do. It's also THE BEST thing you'll ever do, but it's the hardest. And if you don't take care of you and your partner - by making time to be together, making time to be a couple and not parents, making time to be in love and connected and all those things you did before being a parent - then the whole thing is likely to fall apart.

Whether this is what the poster meant as "selfish" I don't know, but being aware of yourself, your partner, and your relationship in this rollercoaster of a ride seems to me to be an incredibly good thing.
Reminds me of one of my favorite quotes from East of Eden

> You have not bought these boys, nor stolen them, nor passed any bit for them. You have them by some strange and lovely dispensation.
> If you channel that ambition into being a better parent everyone benefits.

That's begging the question. Your original ambition doesn't benefit. What if it was something really good and worthwhile?

> for most people their kids will have more overall influence then their work ever will.

This can't be the case, unless you think the amount of 'influence' always increases as generation pass (why?)

My kids are humans, just like me. If we're both selected at random, we should expect equal 'influence' for both. If I have some reason to think I'm above average in influence, then I should expect regression to the mean for my kids.
Why on earth would you need that for a normal car?
Did you read what I wrote? I'm not making any claims about numerical performance. I'm saying there are better choices (in terms of being easy for the programmer to write and debug) for programming other aspects, like network, asynchronous coordination, etc.
I endorse looking at data like this, but I think there is much better way to estimate how kids would affect your happiness: do activities that put you in extensive contact with kids, e.g., volunteer to baby sit for your friends/family, offer to tutor/advise neighborhood kids, and coach youth sports. (In addition to learning about yourself, you're helping out parents and kids when you do this, so win-win.)

Obviously these activities do not capture huge things about the 24/7 job that being a parent is, but they will probably tell you a lot more about how you relate to children than looking at population self-report data.
And you're playing a game of teaching them about what it means - more general what everything in the world means, how to read the world. You will find it frustraiting and interesting, arguably your task is to shift the balance so it's not frustrating for you and your kid, you'll learn a lot about humans, yourself and kids along the way (or not).
I think it's just a speed bump due to running into limits on new capacity. In the US, for example, demand for electrical energy is nearly flat. Once the price of renewables falls enough the existing plant (much of which is only there because the capital cost is sunk) will start being replaced before its EoL.

BTW, the argument being made here against renewables would apply equally well against nuclear. Hail Mary Reactors will also require scaling up of factories to make them.
It would be cheating. The contest rules [1] specifically rule out using domain knowledge.

> Electrolysis is energy-intensive (50kWh/kg) and quite expensive

Solid oxide electrolysis cells have been producing hydrogen at >93% efficiency (LHV) for over a decade now. Some research cells have reached 99%. It is still considered expensive but only because hydrogen derived from natural gas is cheaper. I personally have produced hydrogen via electrolysis at a cost of $2.72/kg. After a 60% efficient conversion back to electricity, that's $0.116/kWh.
Unfortunately the current display model also has several times more resolution than any available VR headset.
Updated the title from 'Fantasy Football' to 'Fantasy Premier League' to stave off continued tedious arguments about international sporting nomenclature.
Allowing access to the data changes the problem. It’s an interesting problem in its own right, but seems much easier to accomplish and arguably much less valuable than limiting input to images and output to mouse/keyboard. Teaching computers to interact with the world is the trick that we want to teach.
