Perhaps the best argument for nuclear energy is that it's a nearly certain, affordable (if expensive) remedy to a catastrophic problem, climate change. How can we - how dare we - risk the lives of millions of people?

I'll add that we especially are risking other people's lives. While most people reading this have reaped the benefits of fossil fuels, likely we and our decendents mostly will survive while people in poor countries die.
I do the same thing.

The rationale I use personally is that the master password might be stored in a retrievable format on my phone, but the phone itself is encrypted (iOS 8). And the convenience factor is strong enough (it's really convenient!) that I'm not discouraged from using strong passwords like I otherwise might be.

Unless someone sneakily borrows my phone and fingers while I'm sleeping, I don't think I'm at much risk.
Yeah, I feel like the biggest fallacy when people are trying to understand "why" a wing works is to try to ascribe effect to this phenomenon or the other. All these different explanations are different ways of looking at the physical situation, but none of them are causal. A wing works because of the laws of hydrodynamics, trying to pick out one aspect as being more causal than the other is just the wrong way of looking at the problem.
I will reiterate, you absolutely don't understand the history and geopolitics, despite having lived here, and, no, the point I was trying to make was not about the school districts but about statistics defined by the city but given as if they represent the entire city defined in the same way as other cities are.

That you insist on thinking "a lot of other cities with a comparable population split" is the same thing shows you do not understand the geopolitics or the makeup of the region.

> Chernobyl killed 4000 as long as you don't count any cancers.

Right from the reputable source link I provided:

"He explains that there have been 4000 cases of thyroid cancer, mainly in children, but that except for nine deaths, all of them have recovered. "Otherwise, the team of international experts found no evidence for any increases in the incidence of leukemia and cancer among affected residents.""
So how does the 'optimization' work? :)

I have no clue about physics, so I'm just curious.

What he said is an absolute truth. Momentum conservation is a fundamental law of nature, and if the air is exerting a upward force on the wing, transferring upward momentum to the wing, the wing is transferring downward momentum to the air. "Transferring downward momentum to the air" is pretty much the definition of "throwing air down". There is simply no way around that.

But it says nothing about the how a wing is throwing air down.
Thank you very much for the explanation!

I think "Digital Taylorism" is more accurate and informative than calling it "scientific management". The quotes let you know The Economist is intentionally using a famous misnomer but I'm not sure that comes across in a HN title where the main title isn't seen first.

I would suggest "Digital Taylorism threatens...." or "Modern Taylorism threatens..." as a title.

It doesn't. It's really a deliberately vague term referring to any physical action designed to put the system in one state rather than another. A thermodynamically non-reversible action, you could say.

I don't see how you can make a single cross-platform experience from a single JS / JSX file. The sample has two different main.js files, one for each platform:

// iOS
var React = require('react-native');
var { TabBarIOS, NavigatorIOS } = React;

// Android

var React = require('react-native');
var { DrawerLayoutAndroid, ProgressBarAndroid } = React;

How can you determine the platform at runtime and dynamically build the layout for each? I'm guessing, we'll have to expose a native function that returns the active platform, although it seems weird this doesn't already exist.

I wonder why the team decided not to abstract the functionality a bit, like Xamarin did with Forms, so something as common as tab view could be constructed in a cross-platform manner? I understand the urge to keep the platforms feeling native, but a little abstraction could go a long way.

Like 3 years ago, Etsy was this hip new thing that my young friends and I would visit for very authentic trinkets. Neat hand-made necklaces, little trinkets in designs no one had thought of.

Last year, I was hunting for pocketwatches, and everything I saw on Etsy seemed to be mass produced in China, literally the same as the stuff I found on Amazon and Alibaba.

This article seems to suggest that they've fully accepted this model for more revenue. The problem is, they abandoned their niche, and there's no way they can compete with the likes of Amazon without it. They've lost sight of the most important thing -- their users.

I guess it's back to eBay for me.
Google really needs to be thinking further ahead.

I think you are right. I am sorry to say I have fallen prey to this flawed argument. I need to migrate to LastPass something I am not happy with and have been stopped a few times because of articles like this one. I'll ascribe it to a lazy approach to evaluating what is being said.
> That fallacy is called ipse dixit, roughly translated as I say so, therefore it is.

That's not what happened though. I pointed out that bureaucrats aren't prudent when spending other people's money, and that's self-evidently true.

For example, you know would not be prudent with other people's money either, or with $1000 you found on the street.

> And that's the fallacy of the excluded middle. Just because (some) bureaucrats aren't particularly prudent when using our money, it doesn't follow that (as you alleged before) the free market is always better.

I was hinting at the fact that since everyone uses someone else's money less prudently than his own, using someone else's money results in 'waste' compared to using one's own, and therefore, all public spending results in 'waste'.

So it's clear that the free market actually is 'always better' in that sense. It's better in all other senses too.

For example, you'd be hard pressed to argue that a state-maintained monopoly or cartel is better for us than no such thing.

Interesting. I'm most fearful that this will be interpreted as "technology is bad! Keep it out of schools!" - rather than "ok, now we have learned that randomly situating computers throughout a school may not be the right approach to introducing new technology into the school in an attempt to improve outcomes", and possibly, "should we revisit the outcomes that we are seeking in this new world?"
So they should have to actually break the law to get justice in a timely fashion? If you're being affected by a law that would see you face criminal charges, challenging it ought to be as timely as those criminal charges; otherwise, it's all too easy to set situations like this up.

While I look forward to the first instance of someone standing up and very publically and broadly violating an NSL to get such an abomination into a real court, that shouldn't be a necessary step. The whole mess needs abolishing, but in the interim, 10 years is about 9.95 years too long.

> I think, personally, I'd've called the initial class ScoreGuts or something

Well, maybe the point is that the original class becomes "useless" once it has been "decorated"; so it doesn't make sense that it has its own name. But it's is also true that, once you get used to program using FP style, mutating variables like this feels "weird".
That is by design. React native isn't intended to be write-once, run-anywhere. iOS and Android UIs are just too different for that to work well.

Instead, React Natives gives you a place (javascript) where logic can be shared between iOS and Android, and a common approach to rendering that leads to lots of shared code.
It also doesn't really make much sense. The Go Language Memory Model page is about memory synchronization, not memory management. This article is about memory management, not low-level details of when writes and reads are visible across coroutine boundaries.

What is surprising to me is actually how small the waste is, especially compared to the amount of energy that was extracted.

One mountain can be used to bury the waste. That is a tiny footprint compared to other, conventional means.

Even a single small hydro dam - itself a great way of making power - covers a far larger area of the earths surface than all the nuclear waste ever made, combined. Compared to coal waste and even the mining waste for rare earths, it is a tiny amount of waste.

On a personal note, I'd say it's pretty sad that a taxi company is raising more than a company attempting to further the technological front. Not popular to say anything against Uber here these days, but this is not against Uber specifically, more the perverted culture that we live in.

Should we all be looking for marginal gains?
>Everyone comes to Hacker News comment threads like this to expound that nuclear is the way, while solar and wind continue their march towards domination.

Except it's not really true. You get solar and wind power when you get it, not when you want it, so it's far less valuable. Once you add storage costs it's more expensive than nuclear.
While it's true that you won't survive long with a lot of 'cracks' in your foundation of understanding, I think there's quite a bit of worth in helping people identify and explore the holes in their own understanding and making this as painless as possible.

I understand that we can't trod new ground if nobody is willing to put up with the difficult slogs, but there's no reason to make things difficult for the sake of difficulty. There are plenty of challenging exercises one can do simply by learning to apply a newfound understanding without having to leap from perch to perch because nobody would explain how to bridge a certain gap.

I think that things are trending in this direction already, actually.
My university switched to DesireToLearn's software. It was terrible, especially when I was trying to enter grades. It was simpler and faster to export the grades, bring them into Excel, make the changes and then upload the new grades rather than deal with their horrid interface.
> why should the artist have any say over what other people do?

Because amongst other things, an artist might want to control what their works are associated with and how they are displayed (known as moral rights in some copyright laws, not sure it applies to the US).

For example, assume an artist makes a song; they get to say if it can be used to advertise things they don't approve of or if it gets remixed into something else. It means that writers get protection against a publisher just taking their manuscript and doing s/Harry Potter/Terry Totter/, claiming it as an original work and selling it with a larger advertising budget than the original author. It prevents someone from taking your pictures or other original works and selling them as postcards , T-shirts and coffee mugs without your consent.
I've seen videos of large helicopters carrying people hovering with their open tail end pressed against a hill and the front a few feet in the air, keeping the whole thing level while dropping people off on the hill, which this could have done better (less chance for error, less fuel?).

I'm surprised no other helicopters have had something like 4 linear actuators that a pilot can control to get this same effect with a bit less of the automation.
> The benefit is that if I get BankOfAmericaa.com and try to get an EV cert, the CA is going to verify my actual company name, which will unlikely be Bank of America or anything similar.

So the first question is, why not? Can't someone file papers for a shell corporation with whatever name they like? Of course "Bank of Americaa Corp" is likely to raise questions, but is it not possible to BS your way through an EV cert claiming to be "Bunk of America Corp", retailer of bunk beds, or "Bank on America Corp", domestic lobby group?

Going through the process is obviously a huge pain for the attacker, but it's a huge pain for a legitimate business too. If the purpose is to make the process expensive then you might as well dispense with the charade and just say "pay us $20,000 and we'll give you a shiny green bar".

And the attacker still has a problem. Everything you know about Bank of America says their website is bankofamerica.com, not bankofamericaa.com. The difference is right there on the user's screen if they're looking for it. And if they're not looking for it then what difference is a green bar? Especially if all we tell them is "make sure it's green" and not "make sure it doesn't say Back of America Corp".

> Where do you see the resistance coming from?

Environmentalists don't want more dams constructed; agriculture doesn't want more water use regulation; industry doesn't want tighter environmental (or water) regulations; residents aren't going to be able to cut back on water usage much more; automobile manufacturers don't want further emissions cuts. Every single interest group wants to point to another interest group and say, "this situation is their fault, make them fix it instead."

I think a better question is, where do you not see resistance coming from?

> we are still in the range of natural variability

And does that make this a more comfortable living situation for you?

> I'd guess that many people who fear upending civilization to avoid CO2 production would agree that a reliable water supply is a priority.

It's true that the recent and continuing decline of carbon dioxide emissions (https://en.wikipedia.org/wiki/Greenhouse_gas#/media/File:Yea...) is "upending civilization" -- we have never been worse off, as a species, than we are now -- but why we could expect those people to agree on how to get a reliable water supply is a mystery to me, given that they can't even be expected to agree on what the problem is.

> Would concentrating on the issue (less water than demand) rather than the causes (anthropogenic or not) make it more likely for mitigation efforts to succeed?

Well, I dunno, I guess. If people refuse to address the causes -- which, even in the face of overwhelming supporting evidence, they seem likely to do -- then I suppose the only remaining option is to decrease demand down to levels that can be supported by the relatively meager amounts of precipitation across the state.

Which, again, makes California sound like a pretty nice place to be from.
And yet it may be interesting to compare it to competing password managers such as iCloud Keychain. Is it less vulnerable to "master password decryption" part of this attack due to its deeper OS integration?

Not that it doesn't have its own vulnerabilities.[1] But perhaps those are more bugs (e.g. not enforcing sandboxes properly) than architectural weaknesses.

The author immediately leaps into critiques of the idea that "rationality cannot be an objective constraint on us". For rationality to be a wholly objective constraint on us, we need perfect interactions with it. The other name for that is infallibility.

My argument is that Morality/Rationality is equivalent with "our beliefs about right and wrong". My feeling is that the author would now say that I am retreating to the Motte. I hold that there is no world where morality and rationality and even science are separated from "our belief about right and wrong". I feel like the author feels like they have a pure connection to the realm of Platonic forms.

Here's my theory about the Motte and Bailey. The Bailey is the poor understanding the author has about the "logic/rationale" behind postmodernism, the Motte is the understanding gained through further reasearch. The author it turns out, is fallible. Perhaps I can now dismiss this construction of theirs as a strawman? ;)
