Yes, in much the same way that passive or thermal (e.g., hot-water) solar designs are a form of solar power.

The principle difference, as others have pointed out, is that when converting heat to mechanical energy, or for electrical generation (mechanical + a generator), efficiency greatly increases as the temperature gradient between the hot and cold ends of the process increases.

There's still a lot of utility from lower-grade heat, for space heating (to about 24C/75F), water (about 60C/140F), and cooking (175C/350F). Even a partial boost can assist with other heating methods.

But for large-scale electrical generation, high temperatures, well above boiling point, are what are needed.

Community thermal energy storage is a thing. That can use either geological formations or specially-constructed insulated structures. Thermal potential may be stored as a hot or cold medium, for heating or cooling.
That's a TIL for me, apparently it all happened pretty recently [1]. I would have expected that to be on HN as a dedicated post when it happened, or maybe I just missed it.

Just because banks hold it doesn’t mean Bitcoin is dependent on banks whatsoever.
> magical pseudo-currency that solves all problems and unexplainably makes everyone richer and richer

That's not what's exciting about bitcoin. What's exciting is that it is the first digital, global money that isn't protected by the proof of violence of the state. The US dollar is the world reserve currency because the United States is the best in the world at deploying destructive power, and the British and French currency before that when they were at the height of their power.

It's a neutral currency that every nation state on the planet can be ok with, because the system is completely agnostic to who the participants are. The only thing it requires is that you have hash power and internet connectivity. Nation states will have proportional power in the system based on their respective abilities to deploy energy and compute power to the security of the network.
Not really controversial but ignorant of how real life law enforcement works. You will never find yourself using tracking data to prove your innocence, that is TV/Hollywood fluff.

You will find yourself on the short list of suspects because you were in the area of a crime. If you actually read some news you will also find that it is often because one of the law enforcement decided their "gut" feeling was you are most guilty loooking and now they have a solid starting piece of evidence to use against you.

I think you have a point, however, there's a fair amount of folks that think news coverage is just fine. I'm sure where you use the word collude those folks use the word "collaborate".

The way I understand it is this: if you have multiple companies covering the same topic using their own channels, then someone has to try to stick out in the variety. This could be good or this could be bad. There's a lot of ways I can think to interpret that image, but I'd say it's probably planted to agitate liberals. That's a company trying to stick out in a negative way.

If they work together, they can produce common narratives -- even if they're wrong, but especially under certain pervasive ideologies that may be trendy at the time. The whole Covington incident and the outpouring of blind rage was a fairly good example of this very thing. Entire reporting fueled off of a tweet and other companies speculative reports. This tells me there's something deeper wrong, or at least - this is not the place to institute a patch.

For those that need an update on Covington: https://en.m.wikipedia.org/wiki/January_2019_Lincoln_Memoria...
So first off, TOTP and similar already solve the "phone is present but offline" issue.

But even if it didn't - how on earth is this meant to work? I'm somewhere that has no cell service, not connected to wifi, and need to login to something on a public computer..

Ok so with TOTP I just get the 6 digit code my phone generated, and type it into the input on the public computer, the site confirms its the expected OTP and I'm in.

How does this work with a QR code? The phone generates a QR code... How does that help me login on the other device? You're assuming the other device will (a) have a webcam and (b) have reasonably easy access to capture an image via it and upload it via the browser...
Cryptonomicon is one of my favorite books of all time, but as Stephenson's success has risen so has lack of editing.

He's the one author that I think would really benefit from releasing both a "mainstream" copy of his works and then a "director's cut" of the same story.

I love science fiction and read a lot of it, but I just couldn't get through Cryptonomicon, I just have the feeling that after a lot of pages nothing is really happening. Should I just keep reading until it gets better then? The start seems super slow with 0 interesting developments.
Interesting, what percentage of DDG search results comes from Bing and what percentage comes from Yandex.
People don’t transact gold either. It is difficult to transport and verify. Gold is though a reliable store of value as creating more is not easy, just like Bitcoin.
Comparing SQLite, DuckDB and Arrow with UN trade data
TLDR: Arrow and DuckDB provide fast database aggregates compared with R's RDS format and, to an extent, SQLite.

It is unclear how much functionality is available for Arrow under R: any comments? It would also be interesting to see a similar benchmark for Python, which could include the embedded version of MonetDB -- an R package for MonetDB/e is not yet available.

Edit: amended the TLDR to reflect jhoechtl's and
wodenokoto's comments. SQLite provided reasonably memory efficient aggregates.
With extremely disadvantageous tax treatment there are very very few situations where married filing separately won't cost you a lot of money.
Yeah - it is just a simple matter of numbers as opposed to pretentiouses or humblebragging. The number of people interested in a book is highest for the surface/casual level and it is seldom that there will be enough demand for often expensive and slow to move texts. There isn't much call for say republishing of authenic 19th century surgical technique books. Maybe some casual readers would buy it at a lower price point but almost certainly not if it is several hundred dollars.
REST is far too narrow to fully encapsulate the features necessary in even the most basic of web apps. A truly RESTful API is essentially just a database. So application backends always ends up being a JSON RPC API over HTTP. Better to formalize that with an RPC framework than zealously attempt sticking to something that is inadequate.

I was referring to something like this.

Here's a hypermedia API entry point I googled up.

GET /

{
"version": "1.2.3",
"description": "Example API to manage orders",
"links": [
{ "rel": "orders", "href": "/orders" },
{ "rel": "customers", "href": "/customers"},
{ "rel": "customer-by-id", "href": "/customer/{id}"},
{ "rel": "customer-by-email", "href": "/customer{?email}"},
...
]
}

My point was, how is such an API served up when it spans resources that are managed by two separate services / microservices - one for customers, one for orders?

Of course this is a simple example, we are smart tech heads, so obviously we can wedge a third service in front of the other two, which exists solely to provide aggregating behavior like this.

But why? Is hypermedia so useful that it's worth going to this trouble? (No IMHO).
Not dating since a few years, but living near a tech hub, the 20-30 year old population was 1.4:1 men to women. You could imagine it was tough, but most single men in that age bracket were stereotypical socially unaware software engineers. Just don't talk anything nerdy and you're golden.

I don't think that's changed. +30yo is a different subject, though, most stereotypes are ironed out by then.
If you live in the Netherlands and have young kids in school this really isn't option. It's how kids' parties are arranged, sports schedules are communicated, parents are kept informed about school. And then it is also often the most convenient way to contact any help desk.

The annoying thing is is that WA became the standard for communications when they were not owned by FB and had a privacy focus. This is why I have no qualms abut trying to cheat out of their horrible system.
yes, consumers want to - well - consume. And not be bothered with anything other than that.

So somebody else has to do housekeeping and hand-holding. That's where apple comes in again, or better, stays for convenience sake.

And to not complicate their own day, Apple just does it the same for all.

... Applications registering as a handler for URL schemes goes back to... at least Mac OS 9. Of course back then it was more likely to be an `ftp://` link.

Could this behaviour be abused? Sure it could. But what's the alternative? Break the decades-old ability to link to some protocol other than http(s) and have the user's OS decide/prompt for how to open the link?
I agree with this. Snow Crash and Zodiak were such taut novels, Diamond Age was a little lush, and Cryptonomicon was a slog for me and then I tuned out.

My favorite remains Zodiak -- I read it over and over as a teenager and when I moved to Dorchester, MA years later had deja vu when I realized how well he captured the Boston area. I used to do stealth rides on my bicycle around Boston late at night because, yes, the cabbies will try to kill you. Fun times.

This article is timely, thanks.

I'm learning this stuff at the minute. And based on the description provided of REST I couldn't marry it up what what the course was later describing as REST. This article has made sense of that for me.
> That's not what's exciting about bitcoin. What's exciting is that it is the first digital, global money that isn't protected by the proof of violence of the state.

No, not really. At all. You're trying to make it sound like everyone is just an anarchist activist trying to fight the power, when in reality it's just people scrambling to make a quick buck.

Let's be real and put it in perspective: do you feel that people such as the Winklevoss twins give a damn about theoretical concepts such as "proof of violence by the state"?
There's lots of different markets around the world in different goods and services.

If you are sufficiently purist, none of them is free or unregulated. But they are regulated in different ways and to different degrees.

You can learn a lot by observing how these varying degrees impact outcomes.
I understand, but the majority of people don't.

I applaud you for speaking/knowing a few sayings in latin, though.

ARMv8 basically exactly mirrors the C++ memory model without any explicit memory orderings (the default on atomics being sequentially consistent).
You need to compare the relative numbers. Bitcoin is being held by 1000x fewer people than the US dollar.

If 100 people control 13% of Bitcoin, then the question is how much Dollar top 100,000 people hold.

> Why was all of this nonsense even necessary? As if the article writer just had to wedge in a completely forced narrative about COIVD apocalypse terror for the hell of it.

It's very obvious the writer is just acknowledging the odd circumstances of the meeting with Stephenson. This isn't Reuters -- the writer is setting the scene for the reader and adding personal perspective. He doesn't dwell on the topic.

Your response about Covid is ironically exactly what you're accusing the author of, an off-topic narrative wedged into a discussion about something else.
My government is far worse, but it doesn't grandstand in public hearings the way the US Congress does.
Owners of coins have absolutely no control over bitcoin. They can't "vote" with their coins for any change in the protocol. Miners can, but to a very small degree. The real control lies in the hands of those who hold keys to Bitcoin GitHub repository, bitcoin.org web site and /r/Bitcoin subreddit. They can do whatever they want - increase block size, change mining algorithm, increase Bitcoin supply etc.
If you think the article provides evidence for any of what you are saying, you should read it again. Do you really believe the 1000 top holders of Bitcoin that control together about 15% of the supply somehow conspired together to manipulate the price?

Yes, there is a lot of small scale shenanigans with crypto currencies, but Bitcoin has become very hard to manipulate due to the sheer size of the market.
But isn’t the dream to have some distributed system that no one can control? As an outsider looking in and comparing to the perceived values, this is yet another reason crypto is not worth your attention.

why I would give access to this tool?
I would say your historical reference is flawed. One could just as well have written an encrypted text on a sheet of paper that would be non-trivial to decrypt (e.g. Z-340). The difference, I think, is that it used to be far more effort to create the encrypted text than it is today.
As someone who's read the paper, do you know how they account for ownership by exchanges? There's got to be a large amount of BTC that is held in Coinbase's wallets, but actually owned by many more individuals.

I.e. isn't the BTC I have parked at Coinbase is in the same wallet as many of their other customers' BTC, and shows up on the blockchain as one owner by this analysis?
The solutions are quite simple. Provide free daycare. Provide 1 or ideally 2 year long parental leaves for both parents. Provide a somewhat generous child allowance for up to 3 kids.

The hard truth is that it's not as expensive or complicated to encourage people having child but for some reason we are trying to do anything except for the things that actually matter: allowing parents that want to spend all their time with their new child this opportunity and allowing parents that can't be bothered to handle all the early mechanical aspects to avoid them.

Cheaper starter housing and for the US cheaper higher education would also help but I'm convinced those are lower priority than targeting the early years.
Wouldn’t they do an in kind distribution? In which case it’s on the LPs to keep their positions.
That’s true, but I think people overall are pretty happy with crypto. You can move more money, faster, cheaper and with way less hassle than a wire transfer. In addition crypto exchanges and services have proven pretty reliable. It really is night and day vs traditional banking.
And to hammer the point home, the spin is consistently and ubiquitously slanted against anything right leaning. Its way past confirmation bias, and yeah, one could argue that the right has its own media wing, except right leaning sources have unilaterally been defined as "unreliable" and are collusively excluded from all manner of popular information sources - stackexchange, wikipedia, default news/politics subreddits...

Reality's supposed liberal bias is an illusion, concocted by a decentralized network of activists who have quietly infiltrated all of our institutions and suppress right leaning opinions with what amounts to bullying. Don't believe me? Try editing any remotely political article on wikipedia with anything but the "approved" narrative carried by lefwting sources with a suspicious consistency.

There is more than enough uncertainty in the reporting of contemporary events for news agencies to disagree while remaining factual; yet, suspiciously, the set of "reliable" sources are nearly always consistent in their interpretation of events and the language they choose to slyly inject political bias into their articles.

Objective journalism is dead, and was long ago replaced by increasingly naked political activism. Sure, it's impossible to be truly objective, but that's not an excuse to constantly manufacture one sided propaganda. Apparently people are so hung up on diversity of skin color/gender/sexuality that they've lost sight of the entire point, diversity of thought.
> I also suspect there is a common thought process of new grads that the quantity of applications is more important than the quality of the application -- sending out hundreds of applications even if there significant mismatches between the resume and the job posting that could be trivially corrected.

In fairness to new grads, the minimum requirements on job posting are often wildly out of line with what the job requires and what the employer will accept. I still meet plenty of junior engineers getting their first gig by applying to jobs that say 2+ years of experience when they have 0.
Why do they jump to it? Tribalism and xenophobia, the latter is one of the few socially acceptable ways of expressing it against "acceptable" targets. It doesn't matter that Bob's Books does a shit job he is one of us. Outside businessmen are The Other. I mean the last time that sort of thing was judged negatively was response to Post US Civil War lynching of "carpetbaggers". Hell the modern use of it for opportunistic moves of politicians is still the same xenophobic arbitrarily designated wrongness.

It seems obvious but nobody ever calls that behavior what it is, along with "cultural protection" which is really an attempt to treat the choices of others like your own property in what would be called overwhelming arrogance in most other contexts.

You've done much more than banning "the other account." Banning an account does zero - it takes about 5 seconds to get a new one.

Here's what you have done over the last few years: banned the external IPs of a whole bunch of large customer sites, highrise buildings, and huge hotels. Losing many users in the process, and turning the other ones into attackers of your site - for fun. like me. Enjoy your little powertrip, retarded unpaid human who's too dumb to replace himself by a spam filtering script.
The difference is that our computing devices have become an extension of our very being. Our thoughts, actions, and interactions are recorded at a granular level never before possible in history, we often don't know what is actually being recorded, and that data can be stored cheaply, transfered instantly, replicated, and searched for mere pennies.

To expand on your comment, I can go in my file cabinet and flip through papers I have chosen to keep with data that I chose to write down, and then drop it in the trash can. It's physical and tangible and it doesn't have a record of who I called, where I went for breakfast, or what I ordered.

Our founding fathers were very clear on their intent with regards to how they viewed governments imposing on the private lives of citizens.
