Meditation under the microscope
To be fair though, this has been a problem for quite some time and mostly stems from many web devs not understanding block and inline correctly and thus applying unneeded divs everywhere even there are enough hooks for their styles already.
This could potentially power a low power beacon every so often. It doesn't seem practical for IOT wearables or for anything industrial at that power density. I'd be curious about the cost, in particular what manufacturing process size can be used for this. 1cm² of wafer can still be quite pricey at .000012 watts.

5°C Delta T generation is pretty impressive though. There are some commercial systems that can operate with 60°C temperature Delta (organic rankine cycle) and recover about 12% of that energy.
Ask HN: What should I look for in a Cowork space?
I’ve been working remote for years but lately I’ve been thinking a lot more about getting out of the house semi-consistently. If you’ve done the cowork thing, what have been the aspects that made it worth it for you?
This still assumes most people are aware of nitrogen's role in fertilizer, ammonia (possibly), etc.
A large percentage (possibly a majority at this point; seems to be fairly close on either side of the 50% mark) of places around here, small and large, now support chip, and rural Upstate NY is not exactly the heart of things.

While I noticed some chip readers seemed slower than magstripe in the initial wave of rollouts, that no longer appears to be true. I've certainly never seen one take 30 seconds to process; that just sounds absurd. 3-8 seconds seems to be closer to the norm.

Of course, gas stations still haven't adopted them. I've even seen gas stations that have updated their machines with new hardware since the chip machines started to appear, that are clearly still magswipe.

The most bizarre thing I've seen so far in terms of the transition to chip machines is at Wegman's, where the regular cashiers' machines will let you use the chip—but the ones at the café, despite being chip-capable machines, have various stickers on them and an insert in the chip slot saying "SWIPE ONLY". Gotta wonder what piece of rigamarole prevents them using chips there.
Having that fourth color (in CGA that would be magenta) makes things look terrible. It was an artistic decision to have black, white, and a single color.

What I found interesting was that I later noticed Matt Brubeck had already done the same thing a couple of days earlier [0], yet mine in the nightly I'd just downloaded was already different.

>Rather, a fair portion of that churn is due to an inefficient communication system or control structure between the player and the game.

I'm not sure what this statement is based on.
There are some differences in governing style though that go beyond "culture" questions.

I'll be honest, I cannot think of a Western nation equivalent of the "great firewall" in China. I'm also not aware of a national campaign to block VPNs, as seems to be happening in China. I'm not aware of Western nations actively blocking access to foreign websites, either, as China seems to be.

Thus, based on this and other examples, I don't think it's unfair to think that the internet seems quite a bit more tightly controlled in China. This is not to excuse NSA style spying, but first impression is I might not even be allowed to openly talk about Chinese spying on Chinese social media to be honest.
You're just provided with a way to automate a task and have Siri trigger it. It doesn't address the OP's key complaint that there's no clarity on what kinds of tasks Siri can do.

For instance, from 9to5mac, these comments -
"While Siri and native integration with the operating system is fantastic, this is still very much the Workflow app, with a few extra bells and whistles. It works and function in a similar fashion by creating blocks that trigger one after another"

"One example of using Shortcuts with Siri is creating a Shortcut that grabs your current location, creates an ETA home, enables Do Not Disturb, and then sends a text to your roommate that you’re on your way home, and plays some music. All while you’re getting into your car, and preparing to leave. And all you have to say is “Hey Siri, I’m on my way home.” Alternatively, you could also just go into the Shortcuts app and start the request there."

All Shortcuts is adding is a way to trigger all of them in one new step. It's like a dumber IFTTT for Siri, basically, one you can't build new behaviors in, you can just script together existing ones. Useful, but it's still hard to tell what can Siri do.
What I usually aim for is that all new code/commits conforms to style and other requirements like having tests etc. Usually it is possible to configure tools to only flag something as a bad build when the new code doesn't conform to those qualities.

However, this means that as soon as you start mucking about in the legacy code, that code need to be covered by tests and formatted to pass any style checks and linters. That is not an insignificant amount of work so plan accordingly.

Also, I find it useful to remember that even if the code is not to my liking (for whatever reason) it might be consistent. I.e. maybe it uses some coding style I am unfamiliar with and I would rather it used another it is often detrimental to start changing it to be more inline with my preferences. Consistently poor code is often easier to reason about than code that is a mix of different preferences and patterns. This also goes for when thinking about introducing new technology to an existing code base (see the lava flow antipattern).
Most of the problems are actually EU-wide, even including a few not-quite-EU countries.

I wonder why this is being downvoted so badly.
12 uW per cm2 is still poor, you'd need gigantic sizes for just a few watts. See the thread down here for some more numbers.

My personal inclination is that anyone of sound enough mind to carefully consider the topic ought to be able to opt for physician-assisted suicide after a short waiting/consulting period as an essential element of agency over their own life.

That's beside the point in that the current medical practice and legal environment doesn't support that position broadly, so with respect to medical indication, the fact that some people die from a given condition does not seem to be a workable threshold for supporting euthanasia as a treatment.
Sure, lots of image sensors pick up IR. But they are not in the millions of legacy security camera systems at banks, grocery stores, college, corporate and campus security systems.

The majority of the surveillance systems of the world are 10-20 years old. they work fine, for their original purpose, and the owners want to add FR, not purchase an entire new system requiring the loss of their previous investment.
> because of his ears... ear positions are the most difficult thing to fake

ROFL :)

Credit Card security model, with CVV, is so broken, but also so widespread, it is cheaper to cover fraud than change it. Especially if card processors (Visa, MasterCard) can shift damages onto merchants.
> Out of curiosity, why do you need HDMI on a speaker?

Well, my TV doesn't pass through anything other than stereo over optical, so lack of HDMI adds on the expense and hassle of an additional HDMI switch with audio extraction to my AV chain if I want 5.1 audio.

Optical also doesn't have the bandwidth for higher-resolution formats. This means, for instance, that's it's impossible to play Nintendo Switch audio in anything other than stereo on a 5.1 Sonos system, as the Switch only supports LPCM audio output. (Also can't do Atmos over optical, but I tend to believe Sonos when they say that it doesn't help with actual sound quality with a regular 5.1 setup.)

> Especially considering that you don’t know how much latency the TV’s signal processing is introducing into the chain.

I don't know that I'd trust TV manufacturers to have lower latency on video input than on audio output, so this seems like a bit of a wash. Furthermore, the Sonos app has a setting to adjust audio latency. Personally, I use my TV for games and with a desktop PC, so any significant video latency isn't acceptable anyway, regardless of video sync.
Thai cave rescue: eight boys now freed [live]
That's exactly what they are doing except the part with "absorbing debt". Banks and credit card companies don't suffer any losses because it's the merchants who absorb them. And that's the root of the problem. Majority of CC fraud is easy to eradicate but banks just have no incentive to do it.
For the lowest-possible power wireless transmitter and camera (black and white, VGA), how big an area would you require then?

Another thing to consider is this is just a guideline - 2-3mm nylon, fixed in place often just be wrapping around a handy outcropping. If you tug on it with any force it will come loose. And then you and everyone in the cave with you are in a lot of trouble.
Well if nothing else Vim is very nice for modifying text strings. So for example I might be writing some markdown for a Stack Overflow answer / GitHub issue, if I can quickly open a tab in my browser format all the text nicely - e.g. indenting all the code 4 spaces in for SO and then yank and paste it back into SO. You don't ever need to leave the context of the browser and you get some added text formatting properties.

It's probably not a huge benefit, but in the same way you can often SSH into somewhere open up Vim make a change and then leave, I can see it being a nice 'clipboard' for my web text. It's not a lot different just to switching to Vim running on your desktop, but I often keep Vim in a separate virtual desktop. I could then also potentially optimise by browser Vim for formatting Markdown / JSON.

It also shows some of the lovely flexibility of Vim.
Break a leg. Well. I broke femur near San Luis Obispo.

I was admitted to hospital, was charged over $19000 (that is nineteen thousands dollars) per night for bed. Just for bed. And it was a "cheap" option with person crying in agony next to me whole time.

Total bill was 74k$ dollars just for hospital service. Emergency services, E.R., surgery, anesthesiology all Extra.

Welcome to US.

P.S. With that prices, hospital easily would make it in top 20 most expensive hotel rooms of the world, except I didn't have a choice but to pay for it.

Art != Communication

And art is not a form of communication ether.

There is no shortage of literature on this topic but good place to start is Aristotle’s Poetics, essentially the first art theory ever written and it dives head first into the issue. In it, Aristotle laments on the corruption of communication at the hands of poetry.
Also, note that very few programmers sit down and write algorithms all day. Boring line of business applications involve little of that skill. I've had no problem with writing such applications for then last ten years, but when came the time to write a simple naive quicksort I've struggled mightily. Those are very different aptitudes.

"hey, an adult is speaking to you, pay attention and answer them."

This is a very one sided attitude and conversation, why would any one want to talk to some one with this attitude?

As an adult I can call out this poor attitude, but a child cant, thats why they are hiding in their phone.
Still sounds a bit much. But let's have some fun with napkin math: Assuming you started reading to them when they were 2, then you'd have three years to read. To get to 1000 books that would be almost one book a day. You'd have to go to the library twice a week unless your library let you lend 7 books at once. I think most libraries only allow you to lend out 3 books at a time.
You can search the actions in shortcuts and quickly see what it can do though.
You use vatlayer.com?
There's also the creatively named Book Reader app that's based on FBReader but that I've found very intuitive.
Sure,but you are judt bolting one heat engine to another (the motor). I'm assuming the efficiency of the motor is better than the TEG (generally the case), so why not just draw power from the motor instead?

This technology is probably more applicable to situations where you have a source of low quality heat and you want to extract a tiny bit of power.
Ask HN: What are your problems with influencer marketing software right now?
I want to understand the current problems/needs of companies which are searching for the right influencer.

What kind of solution is missing? What are companies such as Phlanx doing wrong?

For instance: I don't understand why you have to sign up first, before using the product. In some cases they want your credit card credientals which seems silly to me.

This is surprising to me for when I was in Florida prison in 2003 there was a man who was serving a 15-year "3 strikes" sentence for stealing a rusty $30 bike off a house porch.

I was incredulous, as of course was he, and I asked to look at his paperwork because, frankly, I didn't believe him.

Often, I have learned, when you hear of things like this in the system, once you look at the paperwork you find out "oh, on top of stealing the bicycle you also pulled a gun on someone" or something of the like that explains things.

Not this time...the guy was a drug addict in his 40's who had a lifetime of petty crap, and I guess the judge was in a shit mood the day of sentencing. Since a porch is attached to a house..an "occupied dwelling" in Florida parlance, this was considered a rather serious crime, thus the 15-year bam!

I guess I'm trying to say...it depends upon several factors how things like this are going to be treated. To be honest, I have a few "friends" in Vegas now that are telling me they are really cracking down on fraud and handing out real time behind relatively minor offenses.

Just carrying a fake ID in Vegas with priors will get you a 2-5 year state-sponsored vacation.

True but that's at 5c. What happens if we go to 10c differential? Is the gain linear or does it become more productive as the differential gets higher?

A radioactive device that gives off that much heat wouldn't make sense for something like your TV remote control. However, maybe it could help power your off-the-grid house.

Does a radioactive material exist that could give off a few Celsius degrees of heat for years?

Would it be feasible to have homes use that material (properly shielded) without being a threat to national security and safety?
The US government is somewhat accountable to the public. Their spying agencies however are not. They never have been, have always operated in secret. The public certainly wasn’t consulted on the mass surveillance program.

China is not really "trading" with Africa, are they?

The continental US has pretty much anything needed, they'd probably need to eat a bit more environmental damage if they wanted to actually extract their rare earths for example.
They said if you have an AirPlay 2 capable device you can use it to pair with older speakers. It's right in their most recent press release on the matter.
Its actually auite the opposite. It is not surprising that there is a huge outcry when country x has its spyware programs revealed.
The formula ((p V q) -> (p V r)) -> (p V (q -> r)) isn't valid intuitionistically, though (you can get excluded middle from it by taking q=p and r=⊥), so there's no reason to want an intuitionstic proof.
And to varying degrees the detriment of their family.
It also depends hugely on the nature of the generator - if it's a flexible sheet which can be used to make a tent, then awesome. If it's a rigid sheet then you'd be far better off making your tent out of solar panels even if they only saw an hour a day of sunlight.

> Large businesses are more efficient because they can hire 1 manager per thousand employees.

> If laws were introduced to artificially stop this sort of efficiency, the country's productivity drops. Thus will actually cause more harm than good.

These are basically the talking points of big corporate lobbyists, but they don't bear out. Efficiency doesn't help real people unless it results in better products or lower prices. If the surplus is going to executive salaries, Wall St and foreign investors then it has no value -- or negative value, if those people then use that money to e.g. bid up real estate prices so that real people have to spend more of their income on housing.

And having less of something isn't always more efficient to begin with. The thing may be producing more value than it costs. For example, people love to go to a store and talk to a knowledgeable person about what they need. A few minutes can save hours of research or years of using the wrong product. But what if one store has that and consequently has higher prices, and another store doesn't have it but has lower prices? Customers go to the store that can answer their questions, determine what they need to buy and then compare prices and buy it from Amazon or Walmart. That isn't more efficient, it's just free riding. And when the smaller stores go out of business, "the country's productivity drops."

> A much more sound way of redistribution is to close tax loop holes and aggressive hunting down of those who evade (piercing the veil and all). Recover lost tax revenue, and use it to improve social welfare or infrastructure.

But that's just an example of what I'm talking about. The tax code is highly complex federal regulation that benefits large companies at the expense of small. Replace the complicated income tax with simple no-exceptions VAT and they can't do that anymore. If you sell something in the US, VAT is collected and it doesn't matter where the rest of your operations are. It's basically corporate income tax where the jurisdiction of "profit" is the location of final sale rather than a bunch of complex rules that international corporations can game to pay less tax than local businesses.

But you also have to make sure they don't absorb that revenue on the spending side. As soon as the feds have money to spend, large corporations devise corruption schemes like the one where government-funded research is patented and transferred for pennies on the dollar to big business, so the public is paying for it twice. Which is why spending should be local -- a billion dollars of corruption sticks out much more in a city budget than the federal budget.
Ashampoo UnInstaller 7 Crack v7.00.10 Full Version
The very existence of a great firewall is the hallmark of the failure in their state apparatus to manufacture consent. But of course you can openly talk about Chinese spying on Chinese social media because that much is already rendered irrelevant to the mainstream voice so it's no longer a threat to the state that needs to be contained.
Earth’s core probably has a large fission reactor.
Heaviest elements such as Uranium would naturally gravitate to the center during planet formation, high pressure and temperatures there provide ideal conditions for natural fission.
Explains heat source for volcanoes etc. Would be impossible for such tremendous heat to last 4 billion years from formation, without some kind of additional powerful energy source.
By the sounds of it this is intended for use with things like Zigbee or LoRAWAN.
I think you’ve hit the nail on the head:

> it could also be interpreted as ... [the] inverse of the square root (which is just the squaring operation)

Since the other obvious interpretation is not very useful and has a clearer name—i.e. “the square”—the term “inverse square root” has only one useful meaning, which is therefore how it’s interpreted. (I don’t follow the second option about binary operators.) Mathematical terminology and notation in general are full of ambiguities which are resolved by extensive contextual knowledge. As noted by a sibling comment, calling it the reciprocal square root would be clearer.
The Next Bitcoin Boom Coming Soon?
Every app i've worked on for the last 3 years has fit in one of two categories:

1. Minimal use of Redux

2. Started with Redux, migrating to eliminating Redux.

This has mainly been due to using other technologies for dealing with API data (i'm using Relay, but there are other options), and having relatively little need for client-side state that can't be handled at the component level. When I have needed simple shared state, I just use the context API. If I absolutely needed a lot of client-side shared state, I might still consider Redux, but would also strongly consider client-side GraphQL extensions (both Relay and Apollo support these) so that everything follows the same patterns.
