> they would be very efficient

https://en.wikipedia.org/wiki/Jevons_paradox

> In economics, the Jevons paradox (/ˈdʒɛvənz/; sometimes Jevons effect) occurs when technological progress or government policy increases the efficiency with which a resource is used (reducing the amount necessary for any one use), but the rate of consumption of that resource rises due to increasing demand.[1]

> In 1865, the English economist William Stanley Jevons observed that technological improvements that increased the efficiency of coal-use led to the increased consumption of coal in a wide range of industries. He argued that, contrary to common intuition, technological progress could not be relied upon to reduce fuel consumption.[4][5]

With enough energy crazy things are possible. Terraforming planets, human-lifespan interstellar travel, swarms of space habitats allowing everybody to have their own ecosystem changing to their will. Assuming people won't do it because they don't do it now (when energy is limited) is unwise.

Don't you think some rich people would like to have their own space habitat where they can change gravity, day-night cycle, and the whole ecosystem at will? It's possible with current technology, just very expansive. It creates new real estate from scratch. With enough energy everybody could have one.

I don't see any point at which people decide "this is enough". Always there will be some people that want more.

BTW I agree it won't be a Dyson sphere, it will probably be a Dyson swarm. Much easier to start, cheaper, and has all the benefits of a sphere.
Communicating uncertainty about facts, numbers and science
Right, but I don't think we should glamorize old-style paper voting either. Yes, it is easier for an observer to spot that something fishy is going on, but it is also easy for authorities to dismiss it as insubstantial. Someone obstructed your view of the ballot box for a few seconds? Sorry, that was an accident. Police evicted you from the poll station? Better behave yourself next time. You saw a blatant incident of fraud and you have hard evidence? Well sure, local officials went a bit over the line, we'll cancel the results of that particular poll station. Our candidate still wins.

My impression from fraud reports from Russian elections is that most fraud occured at the local level (where no one was able to precisely quantify it) and from the point the data was inserted into the centralized database everything was squeaky clean.

So maybe some kind of a centralized panopticon surveillance system that the FAAMG are so fond of is just the right fit for elections.
Unfortunately not anymore. You cannot reset your device or add new apps if it is not supporting w10 mobile anymore.

Hopefully most wp8 devices can be upgraded but I would not depend on that for long...
Glad to hear I'm not the only Dyson doubter. Seems too primitive to me. Any advanced civilization will have advanced knowledge on the truth to our reality, and will find ways to manipulate the laws of nature in this or other universes. We're already getting an initial grasp on that with our own developments and we're way behind. Mega structures around a star is just too basic to make sense at the stage where you could build one.
> By why should this be allowed?

Because I want my genes to have a higher chance to survive. It's pretty natural.

> Generational wealth and equality of opportunity are mutually incompatible.

That is true. But there are degrees in which you can enforce this. I'm very much a proponent of the European educational system, where there are more fair educational chances for everyone (compared to the US). This creates equality of opportunity on an educational level.

But I don't agree with high taxes on inheritance. That's not possible anyway. Rich business owners have plenty of ways to pass on wealth to their children without it being considered as inheritance. When you would have high taxes, or even discard inheritance, then you would only hurt the middle class.
>Yes, you would, at least for some parts. Web games often combine the canvas showing the "game world" with DOM showing some UI elements - on which all the usual affordances work.

Only if they care, most don't. In this case, they also don't. It's still trivial to do it, even in Flutter.
Preloading images so they're ready to show when needed, does not sound like unreasonable behaviour, especially on a connection with high bandwidth but low latency.

It will make this kind of example really slow, but if the intention is to break this kind of spying, then that's okay.
> I don't see why advanced civilizations would need let's say 10% of the energy of a star (let alone need to capture it)

Because you're thinking about maintaining status quo of early XXI century Earth (and not that, solar panels won't be enough for that), not about future possibilities.

Space travel, for one, is a huge energy sink if you want to do it in reasonable timeframes. A probe to Mars in a year? Sure, usual chemical rockets will do. A passenger ship in 2 weeks? Now we're talking absurd amounts of energy.

If human history teaches us anything, it's that there's always use for more energy. Hell, recently we've been inventing some potentially infinite energy sinks - like the idea of running the economy on cryptocurrencies. I'm still not sure whether Bitcoin is a conspiracy to have humanity cook itself on Earth, or to force humans to start building a Dyson sphere in the next 100 years...
I'm not an expert on the matter, but I had the impression that you can buy all kinds of vehicles provided you only run them on a racing track. I suppose that also covers emissions. Normal roads are not for sports, so I see no issue banning features that only benefit motor sports.
There is slight difference. First, the number of spoilt ballots is published. Second, sometimes in two-round elections, they can affect whether the candidate wins in the first round or not if it requires to get 50% of all votes including spoilt ballots.
Nordic seem to have the best understanding of what actually makes life easier for embedded software, which is really nice. Most other vendors seem to have done a lot of work to try and make things 'easy' but don't quite seem to have understood the goal.
Ask HN: How to Find Motivation
Just wondering how you guys find motivation/keep focus on side projects after work.

I like the job I do, but I also have ideas that I can build on my free time. but I end up starting but never ending any personal project. How you guys find motivation and / or keep the focus on your side projects?

I can't deny that my daily job drain me a bit and I'm quite tired, but I may find an extra hour per day or 8 hours over two days during the weekends. But I just end up browsing and wasting time.
India’s Water Crisis
Why aren't Xiaomi phones more popular in the US? This is basically a Redmi that costs $150. Don't they support the US bands?
You can build alongside someone else's long-term demonstrated strategy (developing Microsoft desktop software) much more securely than developing a feature in someone else's closed garden.

You can also spread your footprint. As just an easy-to-discuss example, Facebook and Twitter develop for many different someone else's platforms, by supporting multiple browsers [who in turn support multiple OSs], multiple mobile platforms, etc.

It was mentioned in the article that the Internet Archive is in the process of digitizing it. No mentioned of a time frame.
Ok sent you a mail
Is the intention for flutter for web to replace angular dart?
Why? Basic things usually work well. Chemical rockets, firearms, water wheels, wind generators, pumping water for energy storage - these are just few random examples of the extremely basic, brute-force approaches that work really well for us, and see no sign of being replaced. Complexity beyond the point of what's needed is usually sign of bad design.
> Except you can, and these guys are doing exactly that. They're not doing anything criminal.

In Belgium that would be considered criminal (fraud), since you can only receive an unemployment fee when you cannot find a job. You have to prove that you are looking for jobs.

If you put yourself out of the job market, that means you are not entitled to receive an unemployment fee.
Playtime’s Over
What does a good answer look like? It could be very easy to veer into a "culture fit" bias against the working class with a question like this.
3a to N5:

Wider (left-to-right) by a millimeter or two.

Double the RAM.

More storage capacity.

Two quad-core CPUs which are each somewhat slower (2.0GHz + 1.7GHz) than the N5's one (also quad-core) CPU (2.26 GHz). I'm vaguely curious what the difference is between "one quad-core CPU" and "two 2-core CPUs".

I missed my Nexus 5 so badly since it failed catastrophically and Google shut down the product line. This seems like a return to form, hopefully.

The internal speaker was a notable weakness of the Nexus 5 for things like playing music; no idea whether the 3a is better or worse.
It IS baity and it was planned that way.

And we shouldn't change titles but discuss whether or not sites that use titles like these should be qualified/used as sources or get "banned".

This is a worldwide phenomena and it's terrible. It's ruining trust in media and dulls the power of words.
Thermodynamics is OK with this. It's not a way of producing the energy, just a means of storing transporting it which has some advantages over batteries (that said, energy in vs energy out efficiency is not one of them right now)
Which one reason if I'd chose a JVM language I'd go with Kotlin and no longer Scala. The JetBrains people understand and care deeply about developers. Scala compilation of my current project takes ages with the newest Scala/SBT on an iMac Pro 16 core / 32 gb.

I have a side project in Go, compilation, startup and execution is so fast that you don't think it's compiling at all.

I wish language designers would use a fast language for the designer and not the 'see we can bootstrap our own language' approach. Kotlin/Native is at least a good compromise.
Love the JetBrains people, thanks for all their work and putting their IDE language knowledge into a programming language - that's also I assume easy to parse and support in an IDE.
At a glance, macros. Or maybe the "System Events" portion of Applescript, for Linux. Something like that. Indeed, the page would benefit from an explanation and maybe rationale.
It would only be bandwidth heavy for sites that abuse this feature, so that's actually fine by me. And when CSS gets added at runtime, you can prefetch that too.
Vast majority of accidents are caused by drivers (or cyclers, pedestrians) who fail to safely engage in traffic. For the most part, cars don't kill people - people kill people (or, get themselves killed).
I appreciate that you framed this comment as if you're inviting discussion and subsequently shut down all responses by saying that they are "cherry-picking some of my specific examples" and re-claiming your standpoint without any additional evidence. This doesn't promote or invite healthy discussion, as you've essentially closed yourself to feedback before it is even given.
It's a pity councils generally don't let more grass grow wild. It's often a homogeneous standard grass type, weedkiller at the edges. You don't have to leave a patch of land long to get wildflowers growing.

Roundabouts for instance could be an easy win. All the small patches of grass between roads, ets.
Android has been using OpenJDK for a while with no problems.
That's a good comeback

The counterproblem is: capturing energy from a star is one thing, transporting it to where it can be used a different problem (as we even see today with electric cars)

Or maybe they will just mine bitcoin with it, who knows

(TL;DR: next to impossible)
Yea, I was using 64 nanowatts * (1,000,000 making what assumptions?) = 0.064 watts vs a theoretical ~.001 from starlight.

It seems unlikely you could improve the system by 64,000,000 using ambient temperature at night, operating extremely close to a theoretical maximum regularly, and be cheap enough for 4w/m to be useful.
Didn't Red Hat take over recently?
I kind of understand why CSP isn't more widespread.

I tried adopting CSPs on all my sites to full Mozilla Observatory[0] standard. One is a Go based Heroku instance, where I used unrolled/secure[1], though there are a few different packages achieving this. The others are static Netlify deploys using Netlify CMS. For those, you have to include a headers file (in my case I am instructing Hugo to build the site with a .headers media file included, which Netlify parses).

Some observations:

- It's a huge pain in the ass / trial and error process

- The formatting for CSP rules was evidently made to be as insufferable as imaginable. All on the same line, with commas and semicolons being the only separators, no line-breaks, tabs or anything allowed. Seriously, wtf

- When you think you've got it working, some other thing breaks in a weird, silent way

- Debugging CSPs in Firefox is nearly impossible (as for certain in-line scripts, you will need to get SHA values to tell the CSP to let them through. Chrome provides the SHA in the console. Firefox bizarrely doesn't.)

- Trying to integrate google recaptcha with CSP is hilariously complicated

- You should try to host all fonts yourself, lest you need to enable google or fontawesome exceptions for font, CSS, script and svg, because apparently that's what you need just to get an FB icon on your page to work

- Forget about React, or anything using inline-script or styles. Netlify CMS and the Netlify identity widget all require inline styles and scripts. Even generating SHA values for all of those, I could not get this stuff to work. In the end I gave up and disabled the CSP again

And this is for static sites using really simple tooling. I have yet to find a viable way to make this work.

edit (some additional notes):

- Tools like this one[2] did not generate SHA values that were accepted by the CSP. I have tried a few different tools, checked all white spaces over and over. I just couldn't get it to work. Only Chrome returned the proper SHA value.

- I tried fixing a hover state loading in improperly (it flickered on first hover). This wasn't related to the CSP, but because I had to try lots of different things, like load in an SVG sprite, or png sprite, try pre-loading, use some JS, etc. etc. I had to keep changing the CSP to work with this, too. So applying a CSP should only be done at the end of a project. At the same time, if anything breaks from one day to the next, your debugging will now include the CSP as well most likely.

It would definitely be an 'existential crisis' for G if people stopped using Search, Chrome and Android.

They'd be out of business pretty quickly.
If your connection is so slow that background images are a problem, then don't load background images at all. That also fixes the problem.

If you want to prevent this kind of spying, the solution is to load these kind of interactive background images either always or never, but not on the interaction they're supposed to track.
I would guess it's just a poor choice of words and the guys he talks about are probably on welfare rather than unemployment. At least in Germany & Austria you can be on welfare your whole life.
That is more or less correct, look at the Aston Martin Vulcan, Ferrari 599XX, P1 GTR, or just about any street-legal car someone has turned into a non street legal race car.

There is an argument to be made whether a feature should be banned from the road or not. I'm not sure having an EV that can accelerate from 0-60mph in 3 seconds is good for road safety either. How are these two any different?
I don't like Dart much to be honest as well, I've tried used it for about a week to try Flutter and the experience has been pretty bad. It feels kind of Java-like to me, which is really not a positive thing.
You are not being fair by purposely avoiding to include their growth numbers. Their revenue increased almost twice in a year and number of riders increased by almost 50%. Although loss has increased by 4X so things does remain ugly. This is something I don’t understand. Even if you bought revenues, loss should have increased by only 2X. Why is it 4X? Things are not adding up and I suspect Mr Market is going to be very upset.
> Most societies haven't put measures in place to stop people in group B living on welfare. That is accepting them.

Yes they do. They have laws and services in place to track down these people. In practice it's now always easy to make the distinction between someone who can't find a job, and someone who doesn't want a job.

Your "it ain't a crime if you don't get caught" theory is not really accepted by society, government or law.
At Google scale, and given the proved consequences, that's really not the case.

There was plenty in, e.g., the Podesta, Powell, and related hacks, to suggest at the least suspicion. The fact that single-password hacking is a keys-to-the-kingdom event is itself a major flaw. And it's not as if phishing is a new attack vector, the concept dates to at least the 1980s.

And also, Google have changed internal proceses in consequence. But a massive blame component absolutely falls squarely on Google.

There were and are mechanisms Google could implement (and to some extent has) to reduce the attack surface further.

Encrypting contents and doing so independently of access is probably the most significant. Google does not do this, and in fairness, no other major player, not even Protonmail, does this, at least not by default. The problem is hard, it intoduces inconveniences. It is not impossible. Lack of the feature has cost Google users, a small but aware and technical cohort, myself included.

(Protonmail's encryption prevents static-storage-on-disk attacks, including subpoena and insider access, but password compromise remains an extant risk. bI no principally use Protonmail.)

Patterns-of-use fingerprinting (which Google does), app-specific passwords for non-Web access (ditto), special attention to politically exposed persons (PEPs), and exceptional internal access and process controls, yes.

But the mass-sweep attack appears still viable through multiple potental vectors, stream, static, and dynamic (programmatic).
The comment probably refers to the issues their e-voting platform had
FF user here, it does work for me. (v66.0.4 with ublock)
It's more like "you don't need to be afraid of whistle-blowers unless you're killing people through your actions". VW didn't make a small mistake -- their evasion of emission standards has directly resulted in thousands of preventable deaths due to air pollution (they also decided to unethically poison monkeys in order to "prove" that the gasses weren't toxic). Again, whistle-blowers don't just reveal secrets willy-nilly -- there is significant personal risk to being a whistle-blower and very few people make such decisions lightly.

The thing is -- everyone has something to hide, which is why that adage is wrong. But not everyone is hiding a scheme they've cooked up to flaunt laws (and lied to regulators for years when they came knocking) which resulted in tangible deaths as a result. If you are worried that you have a scheme like that on your books, then yeah you should avoid hiring whistle-blowers.
"Also, search query should be linkable (give me URL that I can send others for them to get the same results)" Yes thanks for feedback.
But you see, the problem with space travel is not the lack of energy, it's how to transport it efficiently (rocket equation) and how to use it efficiently to increase speed (specific velocity, etc)

You can throw all the fuel you want at a chemical rocket and it won't take you to Mars in less than a year (more or less).
If you are worried with all the cases, you can very easily display your code as a truth table with nearly no overhead in this way:

myVar =
(!cond1) && (!cond2) && (!cond3) ? myValue_0 : // case 0 0 0 blabla
(!cond1) && (!cond2) && (cond3) ? myValue_1 : // case 0 0 1 bla
(!cond1) && (cond2) && (!cond3) ? myValue_2 : // case 0 1 0 blablabla
(!cond1) && (cond2) && (cond3) ? myValue_3 : // case 0 1 1
(cond1) && (!cond2) && (!cond3) ? myValue_4 : // case 1 0 0
(cond1) && (!cond2) && (cond3) ? myValue_5 : // case 1 0 1
(cond1) && (cond2) && (!cond3) ? myValue_6 : // case 1 1 0
(cond1) && (cond2) && (cond3) ? myValue_7 : // case 1 1 1
defaultValue; // uninteresting default (null, -1...)
I don't get what's wrong with paper voting.

If it takes 3 days instead of 1h to get the votes, I think it's worth the wait since elections are pretty important and with paper you can do a recount, find physical paper that's been thrown in the trash (happens every time in Italy), etc.

Also, these corporations seem to have a strong political bias, and how do we know they're not injecting their software with backdoors that would allow to manipulate results..?
> Tesla is the only one actually attempting to empower individuals with FSD tech. Everyone else has given up and/or wants to monopolize it for private fleets.

There's a guy in a village next to me that is "attempting to empower individuals" with energy medicine (healing people with the touch of his hands). Everyone else, including medicine researchers, has given up on this.
You do realize that covering 10% of the planet in solar panels is the start of a Dyson sphere right?
Just push it up to 100% and start adding "fake" planets until a sphere is formed. :)

Jokes aside, "A truly advanced civilization wouldn't need that much energy" reminds me of "640K ought to be enough for anybody", energy is in some sense like RAM, the more you have, the more you can do with it.

What would you say is the most important workplace perk to you?
With paper voting, an observer can manually count the number of people coming to the polling station. With electronic voting, this becomes impossible, because you either only see the final list or (sometimes) you see the hashes of votes being cast in real time, but you don't know whether it is a real person or just sysadmin voting under name of a random person.

So with electronic voting, it becomes necessary to verify lists of voters.
Just as i dont think he is loosing sleep over what you think.
The first result when I Googled "cost per year to keep a horse" [1] claims that the average monthly cost is from $200 to $325, and notes that is on par with a car payment.

It's amusing to contemplate whether it would actually be feasible to have a decent sized modern town in which horses, rather than cars, are the main form of transport.

If that article is right, they would be about as affordable to the owner as a car. And note that they all come with better self-driving software than any car currently for sale to the general public, and probably better than any that will be for sale within the next decade at least.

They are generally slower than cars, though. A walking horse goes around 7 km/hr (4 mph). They trot at about 13 km/hr (8 mph), and can easily keep that up for hours.

They canter at 2 to 3 times trot speed, but can only keep that up for about an hour over reasonable terrain, which I'd hope a town would have. They can gallop a bit faster, but not for very long.
