Absolute nonsense. Motors are do not care whether they are generating or consuming electrical power. It is a fundamental fact of induction that rotation in the motor creates a reverse voltage- motors literally would not work if they did not have very similar efficiency as generators.

The only differences between a motor and a generator in practice are cost optimizations and fixed-frequency optimizations. Industrial generators run at fixed speeds, unlike EV motors, so they can be built more cheaply. EV motors are not any less efficient when used to recapture power.
One thing I hear frequently against wind energy is "but what about the birds?" Usually this is said by someone who politically doesn't care about wildlife.

1. effort is put into abating the issue to some degree.

2. billions of birds are killed due to human activity. Number one is house cats, but impacts with windows and cars is orders of magnitude more than due to wind turbines.

3. wind power displaces gas and coal power. the effects of pollution (particulates, mercury, etc) is far worse than wind turbines for birds. not only that but it is better for anything that breathes oxygen, including humans.

So if the "what about the birds" crowd actually cared about birds, they'd push for wind power over coal. But it isn't about the birds; it is a pretext for keeping the status quo.

Ask HN: How to learn about industrial power?
I love infrastructure, and thinking about the things that make society work. I know a fair amount about information technology, but I know almost nothing about power: AC power, power generation, delivery, "multi-phase" power, load management, etc.

Is there a good book, or Youtube series, that does a start-to-finish lesson set on AC power and the grid?
And clearly could be! Apple just drew an arbitrary line at 6 years, 7 would be doable.
> and by the way, a bunch of chipset blobs will be compiled against those kernel headers, so changing kernel versions is pretty much impossible

Binary drivers can be reverse engineered and reimplemented for the new kernel. This takes a lot of effort since it requires following a "proper" clean-room methodology when doing so for interoperability purposes, but is otherwise doable. A complementary approach is to forward port the minimum set of features that's required for Android 12 to the older kernel, in a way that carefully preserves the portions of in-kernel ABI that the binary drivers depend on.
I think with NYC it is the mismanaged part more so than underfunded. Limiting cities (and people) by having them live within their means forces better management. When that doesn’t work I feel the solution isn’t to pump more money in but rather to seek out alternatives. The market does that automatically - people will choose to live elsewhere to avoid ever higher local and state taxes, or to avoid an inadequate subway system. The country addresses the problem by decentralizing away from NYC, in your example. Of course in reality it doesn’t quite play out in a perfect idealistic way. The alternative is that the nation pump money in but also control NYC. Shenzhen may be a partially planned city but it isn’t also independent in the way American cities are.
Hi, one of the developers here, we use electron because its hard for our small amount of devs (there are about 4) of us to maintain multiple clients, this is the same reason we use the same web client for mobile.

> the tests / scores do not reflect the actual value or performance of someone

Yes. 100%. In my physics class last term, performance was so consistently poor on exams that the minimum score on exams was 40%, and you could earn 15+% on top of your final exam just for showing up to class. Instructional quality was very poor, due in part to the online format. Knowledge retention was equally poor.

If college is to move online, it needs a fresh start. Classes need to be designed for online interactions rather than in person.

Separately, I'm having trouble parsing your comment, but I'm curious so I will ask: when you say "the boy rebuts", who is the boy here, yourself? Or..? Maybe I'm just not familiar with this turn of phrase.
I'm not sure why infinite growth wouldn't be possible on a finite planet (even if we assume that "on a finite planet" is indeed a real constraint). Growth doesn't imply greater resource use.
I disagree with this - here's my experience. I started training for competitive programming in college. One semester in particular I spent 20-30 hours a week training, and some of my grades suffered as a result. But I got a lot better at algorithms. Years later, what skills do I remember from college? Very little, but I definitely remember the algorithms. Further, converting specifications to code and general problem solving became noticeably easier after this period. As a result, the jobs I've had have centered on problem-solving and interesting technical challenges. I'm always surprised when an idea from that period suddenly proves itself useful.

Also, even if training for algorithms questions was purely a matter of signaling with no positive externalities - it's actually a much faster and easier process than getting another degree, which is a common alternative.

TL;DR If you put in the time, it can absolutely change your trajectory in ways that you might like a lot. If you don't, how will you know?

I don't generally like to be the one to blithely trumpet about personal responsibility, in part because I tend to be more of a "civic responsibility" kid of person. This, though, seems to me to be pretty unambiguously a situation where personal responsibility needs to take over. There must be a limit to how much responsibility we try to foist off on others.

As someone who's been using Proton for years, I've continuously been quite impressed about how open they are about the limits of what they can offer. As a company selling me a product, they do a great job. But they are still, at the end of the day, a company selling a product, and not my life coach or personal attorney. It is not their responsibility to anticipate and enumerate every possible way the legal obligations under which they operate could play out in real life. At some point, it's on the customer to have enough of a grasp of civics to understand what court orders are and how they happen.
Our problem is more about in-fill development then taking up land. Why would we want to make more cities? Better preserves the wilderness.
If solar is used instead of nonrenewables, regardless of whether load has peaked, you decrease carbon output for each watt generated. In the chart on wikipedia, it looks like you could double California solar output without adding storage. If you want to provide 100% of your energy with solar, you'd need storage. But we're not at that point yet.
Same here. The fact that this is the #1 item on their blog post gives me concern as a paying customer.

They cannot and should not guarantee this. It is a losing strategy.

They must educate customers on the limits of Protonmail. Or at least, whoever takes their place will. Protonmail looks DOA at this point.
It's actually sad for HN that none of you have been able to cobble together a coherent argument.

The only actual point made (ad nauseum) was that 'Germany contributes a surplus to the EU' - which is common knowledge.

You've lost the gambit if you can't make a point and only resort to name calling, you're only making yourself look bad.

The very fact that a mutlibillion dollar EU subsidy is going to Germany, ahead of less developed economies is a hint of evidence of consolidation in Germany.

The battery subsidy makes up more than 10% of the 'transfer imbalance' paid out to Germany to the EU, so it's fairly significant.

But the greater theme of centralization of power in Germany is obviously happening, it's not even controversial.

"The country’s outsized economic clout has made Berlin Europe’s political fulcrum, " [1]

Given a weak France and absent UK, Chanceller Merkel has the 'final word' on all important issues. She appointed a unelected and unknown member of her own political party to the President of the EU Commission as a pretty good example of that.

GDP per capita in Germany, France, Italy and Spain since 1990 [2] quite clearly demonstrates how after the introduction of the Euro, beyond a small bump of financial euphoria, that the Euro has considerably favoured Germany over those countries.

Absent any control over monetary policy, Spaniards etc. are left in the lurch and there's no reason to believe they will ever get out.

They are held in a financial straight jacket.

The few billion pounds they receive in EU subsidies are worthless next to to the existential harm to their economy. They are being turned into a Poland, with much of their talent leaving -> for Germany.

"Spaniards move to Germany in record numbers last year" [3]

The EU is beginning to look like what would happen if all of the Americas i.e. USA, Canada, Mexico, Brazil, Colombia formed a 'Federal Superstate' - there would be massive consolidation of power in the US via acquisition, talent migration etc..

"Germany is Doomed to Lead Europe [4]

The mechanisms of the trend are still debatable, but that it's happening is obvious.

Hmm. I'm intrigued what they come up with. The creator is something of a firebrand, who tends to 'no true scotsmen' other OOP languages. His ideas are interesting, but often seem impractical in other languages. If he comes up with something effective, I suspect it will indeed feel similar to lisp, and not in a bad way. Even what he's showing right now feels similar to Wisp-syntax with an OO twist.
To me the set of issues that come with building up a pre-existing city/town are similar to those faced by companies and municipalities looking to lay fiberoptic cable for internet service: endless political hurdles and obstructionism coming from the numerous groups and individuals involved, slowing development to a crawl or stopping it altogether.

It's no wonder why this project is pursuing a "clean slate" approach.
Honestly…people who toss out the whole “horse dewormer” talking point should also refuse to take penicillin if your doctor prescribed it because they also give that drug to horses too.

It’s not just a “horse dewormer” folks, it’s a “people dewormer” that has also been used in anti-viral treatments as well. Argue that’s it’s not effective, but stop pretending that this isn’t a drug that is prescribed to people all over the world.
These days Java applications are supposed to embed the JVM using jlink images or even native installer (see jpackage). So you shouldn't even know if the app is written in Java when you run it.
As a "westerner", I know so little about the world's history.

I didn't know, for example, that movable type was not invented/perfected in Germany, by Gutenberg, but centuries earlier by Bi Sheng in China.
Framed like that it’s hard to imagine choosing one or the other and the answer might be intractable. A more interesting question might be: What would it take to align policies around housing for everyone with policies around increasing the prices of homes such that the two things are strongly positively correlated?
You might want to look into regenerative farming, which actually builds soil, along the way capturing tons/acre of CO2, improving the ability to capture and hold rain, thus providing a way to deal with drought and climate change.
Load following with nuclear is hideously uneconomical though. Even in France they use non-nuclear for much of that, for example by selling or buying power to/from neighboring countries.

In any case, the problem with nuclear is that existing nuclear technology does not decarbonize the world. World primary energy demand is 18 TW. This would require 6000 nuclear power plants (3GW(th) each), if today's reactors are used they'd consume (the 235U in) 1.5 million tonnes of natural uranium per year. Total world uranium resource is a shade over 6 million tonnes, so it would run out in four years.

To power the world with nuclear one either needs seawater uranium extraction (scaled up by 12 orders of magnitude from what's been done so far; 170 km^2 of ocean area for each of those reactors; the power/area is much worse than PV) or breeder reactors (which France has given up on.)
1. No enterprise will withdraw from the EU market because of this. There are too many customers with too much money in the EU. It's a bigger market than the US.

2. That would actually be good, the amount of models aims at confusing customers. But also: Why would that happen? Many models can (and do) share the same spare parts.

3. Prices are already as high as they can be. They do not get lowered because production gets less expensive, they get lowered because of competition. This might have an effect on prices if the competition was very high and profit span very thin - which might be the case for the cheapest budget phones. For something like an iPhone? To my knowledge they are already utterly overpriced, as is tradition (https://www.forbes.com/sites/ewanspence/2017/11/08/apple-iph...), then it will have no effect there.
I can see how then a journalist source could use this to help prove their integrity. And I like that as a solution for that...

But - I don't really see that as the issue today. Those outlets that are interested in lying don't have to participate in this Blockchain chain of proof system. The malicious entities like political groups cited in the article definitely don't have to participate. It's still really on the viewer/spreader of the fake images/misinformation to verify the images, and to only rely on verifiable images. But I think a system like that would leave out most of the population who simply don't care.

Perhaps my worry about leaving out that chunk of population means this problem is unsolvable - and therefore my point is unfair. But I do think we need some solutions that are practical for widespread acceptance and use. If I can't imagine my parents (who are tech literate) would participate, and can't imagine some of my non-nerd friends wanting to participate, I don't think it solves the problems I'd like systems like this to solve.
Where am I “moving goal posts”? I’m saying the law is reasonable because clearly Apple could follow it and, hence, so could other manufacturers.

Germany buys power occasionally but is a net exporter. Main import country is France which is mainly nuclear, maybe you heard someone quote partial results for this year where most have been from the Netherlands that mainly burn various sorts of fossil fuels?

In any case it seems like an unreliable source.

Example of German power imports:

I know what you mean, most Americans can't afford enough real property for a garden of any kind themselves. Fewer and fewer every generation.

Depending on how you do the math that's an even less-than-subsistence level.

Especially when it was such a prosperous nation merely 60 years ago, in spite of productivity being statistically much lower then.
My methodology is well known: it is an educated guess.

And no, I still think Western civilization including the press is pretty nifty compared to the alternatives, I just try to apply some pressure to get it to self correct.

Every time I join a new team, I get my hopes up for retrospectives. I contribute ideas about how we can improve how we work for the first few months.

Then I realize that my suggestions are ignored and "action items" never have follow up. I revert to contributing nearly nothing. I usually come up with a "what we did better" item so that I don't appear completely disengaged from the process.
My understanding of US law (which could be wrong) is that they need probable cause everywhere in the US if it's going to extend the duration of the stop.

> One issue is that unlike x86/x86_64, there is no generalized abstraction platform (similar to BIOS/UEFI/ACPI description tables) that enables "one kernel to rule them all"

Windows on Arm devices use UEFI + ACPI, including Windows Phone starting from Windows Phone 8 (2012!). That allowed even the latest releases of Windows 10 Mobile to work on totally unsupported devices (1st gen WP8 devices) when that existed.

It's not an Arm problem, it's that the Android world didn't bother really tackling the problem for a long time.
I'm very curious, have there ever been any "cities from the ground up" projects that don't turn out to be total shit that end up just reflecting the urban planning fallacies of the day? (Looking at you, Brasilia)

I mean, all of the cities that are most "livable" in my mind are old cities that were designed before the car and thus have enough density and public transportation to make things both close and also the kind of place where it's fun to just walk around.

These "master planned cities" always end up like houses that are designed with all these pretty rooms that nobody actually uses.
The path to building a city involves first building a small town with some kind of economic activity. Because of a lack of people (especially young people), it's hard to create a brand new city with a vibrant economy. Most of the existing young people in America move to existing big cities. Small cities are becoming bigger.

This is unlike China where cities were built en masse to house migrants from rural areas. America just doesn't have the same volume of workers.

America is still pretty empty.

There are a lot of information security discussions that only take place on Twitter, so it's kind of a self-perpetuating situation.

The entire reason I signed up for a Twitter account, after something like 5 years of refusing to do so, was that I asked for some clarification on a post to Full Disclosure, and was told something to the effect of "this has already been discussed at length on Twitter". I had done a bunch of web searches already, and none of them had turned up the thread they linked to, but they were right.

I wouldn't say I'm a fan of Twitter, but because of that situation, I discovered a lot of other discussions in other fields that I wouldn't have seen otherwise, so it seems like a net positive.
Laterally, the amount of CO2 my existence releases each year is of absolutely no consequence to the global environment. The amount of CO2 that 1Bn others like me - or 8.5Bn if overall living standards increase, however?
I don't think this work as this is just rent controlled housing. Better to cut the unnecessary red tape and let developers build more housing.

Browser choice on Apple's iOS: privacy and security aspects
That’s fair. But there needs to be a point somewhere that you just get work done.

I absolutely agree that runtimes, frameworks, and server code should do a better job at trust and sanitization, but you will always get to a point where if you want to get something done, you need to do the work.

I guess I’m skeptical that eval() or runtime.exe could or even should take in lists and configs of what the code is allowed to do and monitor for it during execution. It seems like doing that would add countless issues and complexity, but more so just kick the can down the code to another layer with the same eventual issue.

The point simply is, as long as renewables almost never exceed the grid load, there isn't much to store. Yes, as renewables are exceeding the grid load, storage becomes more important and then storage will be pushed harder. It would also help if some regulations limiting the commercial success of storage would be dropped, like paying the EEG fee on stored electricity.

That said, storage is growing, a 1GW DC line to Norway was put into operations recently.
Claptrap.

1) this is whataboutism. One can ask about one thing when another thing exists, it's not a valid rebuke to say "what about that?". I have given no opinion on that BBC story either way, as it's not relevant. I'm not the country that I'm in, for starters. I would gladly criticise its politics when it's on topic and in good faith. Here it is neither.

2) "shocked" is your spin, and an inaccurate one. I specifically said "curious".

3) as you are repeatedly refusing to address, these are not actually comparable - who in the US case is comparable for the armed forces minister talking about the veteran? Who in the US case has the remit to talk about veterans, specifically?

This is a waste of our time.

Sounds great until companies sell the license to maintenance as the last buck to squish from a product to a third party that will jack up the price just to keep the service running. Better to either force an open source/schematics approach and let the community keep it, or force to sell a certain number of licenses for maintenance.
Proton's homepage needs to say this. They must educate their users to live in the future. Attackers are always getting better.

It is not just easier. Agile avoids assigning people to tasks until tasks are started in an iteration, or continuously as in kanban style Agile.

This means you give up that beautiful "network diagram" CPM schedule estimate with no overloaded resources. But because of the nature of most software development projects, it becomes a burden, or a lie, within weeks.
Yeah, it would be possible to make it faster. But do you find it useful? It's a fun project that I have build over the weekends. Not sure whether someone who use it. lol
Not really true when you consider systems costs [1]. The way Korea and China and Russia are making nuclear plants right now, nuclear still has a huge role to play. If you look at the current boondoggles only then I could see why you'd think what you say.

There's a non-storage solution to the duck curve "problem" which is just to waste some solar power.

As long as you come out ahead overall its still a good idea.

It's like saying gas flaring is a problem and we have a desperate need to solve that before getting rid of coal. Well, it would be nice, but overall swapping coal for natural gas is a good thing regardless.
