To put this in perspective, YouTube (243.6 tw/h) uses about double of Bitcoin's (124 tw/h) energy consumption, but there is no outrage about that. People care about the environment if it doesn't take away their comfort, airconditioning use is about 2000 tw/h globally, expected to triple in the next 30 years, some of the outrage on Bitcoin is being written in airconditioned rooms by people that drive combustion engine cars.

If you compare Bitcoin's environmental footprint to the whole financial system with air cooled offices around the world, with equipment, server rooms it doesn't come close.

A positive side of Bitcoin mining is that it's geographically independent and it can move to where they have too much energy which cannot be stored. In some cases the abundance of energy would be wasted through gas flaring which puts more CO2 into the atmosphere. Now they can get rid of their excessive energy and store it in the form of Bitcoin.

Well, is it a score based on your current economic situation, or your past use of credit?

Here in Norway you're evaluated/scored based on some metrics like income, job security, job prospects, education, assets, debt, defaulted debt in the past, fixed expenses, etc. I think when Americans talk about "credit score" they talk about something completely different, namely their insane system where your score is (positively) affected by taking on and managing credit card debt. In that fucked up world, two debt-free people with the same income will be "scored" differently if one of them happens to use a CC to buy all his groceries and pays off the card each month, and the other buys the same groceries on debit. Surely you don't have that insanity in the UK, do you?
I’d be really interested to know how much motion the current terminal can tolerate? Does it lock at the slightest vibration or only if moving at vehicle speed?

I’m thinking about putting it on a boat at anchor or at a dock.

> The New Model M is a typing keyboard, not a gaming keyboard. If you care about “ghosting,” it’s not the keyboard for you. Ghosting is when a keyboard stops registering new key presses when you hold down multiple keys at the same time.

I was under the impression that most games prized compatibility with normal membrane keyboards, and so chose keys that don't alias.

For example shift, ctrl and alt keys are less prone to aliasing as keyboard designers know you'll be pressing them and other keys at the same time.

Seven decades of financials around nuclear are pretty brutal too. Even keeping existing plants running is not cheap. E.g. France imports cheap wind at times when it has nuclear surplus that is just more expensive. They are actively planning to gradually replace nuclear with other options as plants reach their end date.

IMHO the potential for fusion long term is amazing but unlikely to happen first half of this century. Nuclear options short term makes sense for some niche use cases but it is a hard sell on the grid given prices for wind, solar, and battery continue to trend down from already being vastly cheaper. Anyone looking to sell nuclear probably should be planning for 1-2 order of magnitude in cost reduction just to keep up.
Therac 25 saved lives.

Yes is had critical errors that caused harm, but it was also life saving machinery.

To be taken seriously on this topic, you need to look at harm vs good. And unfortunately perceived harm as well, since we live in a clown land and it affects reality.

Therac 25 did stop a lot of innovation because of societies unwillingness to accept computer errors equivocal to human errors.
Thanks for that quote. Turning this around we get: "On about fourteen days within the year we'll be above the average price. And on half a day in the average year we'll charge 150 times the average price."

And now this is not the average year.
Increasing the money supply doesn't inherently cause "the rich to become richer". Yes, asset prices (both stocks and real estate) tend to go up, but that's because the underlying asset has about the same value but that value requires more dollars to represent - it's not the asset value that has gone up but the dollar value that has gone down.

What it does do is advantage debtors (since the intrinsic value of their outstanding debt, which is a fixed number of dollars, has gone down) and disadvantage creditors and holders of cash (since the intrinsic value of their loan/deposit or cash, which is a fixed number of dollars, has gone down).

Some rich might be debtors (those who've borrowed to invest in assets), but some poor might be debtors too (eg. student loans, large credit card debts). It would seem less likely for poorer classes to be creditors or holders of large quantities of cash, though.

Wage stagnation is a different matter. A priori, you would expect increasing the money supply to cause wage price inflation alongside asset prices. The fact that this isn't occurring means some other effect is in play.

The idea that someone would suggest the Spectator—more reactionary troll factory than magazine at this point—as a response to someone who feels the NYT is pushing too much of an agenda is absolutely hilarious.
Some people are rich enough never to need to consider withdrawing their savings (and cautious/lucky enough to avoid scam exchanges and keep their private keys safe). Others are not.

Oh, and "the rich" don't have "dibs on the freshly printed money" in the normal economy (arguably they do in a crypto economy because mining rigs aren't cheap...). The newly printed money is credit for people and companies not rich [or liquid] enough to have the cash to pay, and specifically it reduces the cost of borrowing because borrowers don't need to rely on rich people agreeing a fee to lend their money until it can be repaid.

Hello,

The reason that people don't take the 20%/year arb is that they are taking arbs that pay more than 20%/year.

An additional reason, at some venues, is that the venue does not allow you to use 1 BTC to fully collateralize 1 short BTC future. At those venues, if you do this trade and the price of BTC goes up, you begin to pay interest to borrow dollars for your paper loss on the futures half of the trade.

Edit: for CME in particular, I don't know, but I sort of expect that you cannot post collateral in crypto.
interesting! Do you know the license / copyright terms for that data?

Consciousness: Here, There and Everywhere?
"I know I am conscious: I am seeing, hearing, feeling something here, inside my own head. But is consciousness—subjective experience—also there, not only in other people's heads, but also in the head of animals? And perhaps everywhere, pervading the cosmos, as in old panpsychist traditions and in the Beatles' song? While these kinds of questions may seem scientifically inappropriate, we argue below that they can be approached in a principled and testable manner. Moreover, obtaining an answer is urgent, not only because of difficult clinical cases and in our interactions with other species but also because of the advent of machines that are getting closer to passing the Turing test—computers programmed to perform many tasks as well as us, and often far better than some brain-damaged patients."

At least Ext4 repeats the complete superblock at the beginning of every block group, so yes, it is not only remotely accurate, but entirely accurate. In the case of GPT, Linux requires explicit command line options to enable alternative GPT use, but do you know this is true for all systems in existence and all versions of Linux?

> Rebooting and re-detecting everything between partitioning and mkfs is not part of any ordinary OS installation procedure

Yes, I've personally bumped into this on desktop and unattended server installs - numerous times.

But you're externalizing the onus to prove cases where some hacky approach won't ever break when there is a vastly simpler way to avoid this entire class of problem. This is exactly the reverse of sound logic -- I'm offering you concrete real world examples of why you should avoid the hack and you're simply ignoring them

At this point I'm considering this not only to be offering up worst-practice advice, but actively trolling. Possibly the worst case of "a little knowledge is dangerous" I've seen recently. Regards
it’s certainly your right to believe that, but I don’t envy you the frustration and alienation that such an approach can lead to with others who don’t feel the same way about conversation as you do. Your challenge does present an interesting question for other greys, though:

What process of data collection and rational evaluation did you use to test your hypothesis that it’s beneficial to your human development to disregard any story that doesn’t have the degree of supporting evidence you require?

I have a hypothesis that few are truly applying the principles of grey so deeply, as it’s quite a cognitive burden to do so, but to decry the question would contradict their principles to the core, exposing unconsidered cognitive dissonance that - if they’re rational enough - would force them to question their entire belief model to its very core. And so, instead, they will challenge the question itself, rather than apply their belief’s principles of rationality to their own beliefs.

Your datapoint in this matter would be a valuable contribution to my rational evaluation of this hypothesis, but of course I understand if you feel unable or unwilling to contribute. I shall continue developing it regardless, for any future encounters with greyfolk.

It would please me greatly to find that none are willing to respond to it, as that would perfectly contradict your belief using the honorable practices and methods of the greyfolk themselves. But it would please me most to find that they are able to reason and respond to such a question, and acknowledge their own irrationality if any is exposed, because it’s more important to me that they integrate rationality and human nature than it is that I be right.

(One caveat. The question you I expected you to have asked is why I would consider it appropriate to make such a statement without defending it further, and how I could possibly expect any outcome from that other than complete disregard by all readers. Your reply ignored that rational opportunity in favor of being dismissive. It’s a curious choice that conflicts with my read of you as a grey rationalist who’s set out to try and promote rationality at HN. If that is indeed your mission here, feedback duly noted so that you can improve the quality of your evangelism. If you aren’t a rationalist, I apologize for my misread and intend no insult by describing you as such, and I will take no offense if you simply disregard this entire reply.)
Oh *dear*. I definitely tripped over there, and I didn't even notice.

Yup.

One thing that I like in Sweden (and the same most likely goes for other European countries, too): kindergarteners are routinely taken on field trips via subways, commuter trains and busses. By the time they are out of kindergarten they know the public transit system even better than some adults.

So I guess "love" is to you also a nonsensical incoherent term? It is not to me, it is very useful and produces a lot of great ressults in my life, and the same goes for free will. Then we live in a very differnet universes. If you're not going to put more effort into understand something new, it is not my job to make you understand it.

Also I couldn't because without understanding what kind of "logical definition" you supposedly have for a term like "love" it is impossible for me to know what kind of logic you expect to find in a term like "free will". There is like 10 differnet ways to explain it with different kinds of logic, how am I supposed to know which one you want to hear? That is the beauty and utility of intuitive terms, that they gather together so many different meanings and are not limited to some inferior mental ego model/rigid definition.

So you couldn't even find one example huh? That link not people talking to GPT as a converstaion with an sentient being. That's people playing an RPG with procedurally generated content. In the same way as when people also play Tetris sometimes. But we don't assume that Tetris has free will either.
nuclear does not need to compete with wind or solar. Build as much wind and solar that is possible, and don't let nuclear investment impact solar or wind investments.

Nuclear compete with energy generated from fossil fuel, either locally or bought from neighbours, and future battery technology. The waste problem of nuclear is a problem, but not as big as the waste problem of fossil fuels.

Right. I've yet to see any combination of easy/sane setup for jwt (beyond the fact that it's somewhat standard, although less standard than basic auth).

You might set the jwt to expire in 15 minutes, for a 5-10 minute session allowing for clock drift - and just eschew the black list.

But now you need a longer lived "refresh token" and a service endpoint that handles that, along with a black list.

It is "simpler" in the sense that: your app have two separate auth/clients - one is very simple - gets a jwt token and renews every ten minutes - the rest of your app simply uses the jwt.

On your server side, you can have a dedicated/simple service that only renews jwts given a refresh token (checks refresh token blacklist) - and your other apps blindly trusts the jwt (checks signature and the short timestamp).

You've now reimplented half of kerberos - along with "pass the hash" - and at least you can reason about the trade-offs you've made...
main thing I've seen on mark rober's youtube is that it allows you to really scout out locations with a speed unheard of for rovers.

That's a good thing. Less completely means more energy for interestingness, and less expense means more accessibility.
Let me try. Text is anything human-readable which supports easy editing in WYSIWYG way. For example: XML, maybe JSON, non-obfuscated source code, LaTeX notation for math, vector images, chess notation, etc. Diagrams are not text but they are easy to be describen in plain English, much easier than memes or photos.

Electric circuit is a beautiful example between text and non-text. You know EC is drawing but any EC is made of hierarchy of two-port networks, so it is like system of equations written in unusual for mathematics way. You can add or erase any element or change any nominal and recalculate a new circuit instantly. If you have a friend working in an electronics, you can give him any valid EC and ask him what he gonna do with it. His answer will be reading, not just looking at.
I mean, customers from all over the world using an USA ISP for their internet access, which can be tapped easily to gather mass surveillance data is a very valid reason to be paranoid :)
> low margin retail and grocery does it too with coupons and whatnot

Yes! I was going to mention that this is really a pretty universal feature of "pricing", but decided that was too controversial an angle on what was a rather simple point.
Notorious has at least two similar meanings; the more common one is "known unfavourably", the second meaning is a neutral "known", not positive or negative.
Most people only see the word used in the negative light so shy from it in the neutral use case to avoid being ambiguous or assumed negativity.

Using it with an adjective to clarify the meaning here is fine.
I find your misspelling of "machines" charming.
Ah yes, an 'All time high' attracts new people and new research and, as with every cycle, people find out Tether is a big risk. And as strange new financial products are hyped and the market drops in a few months, people flee to Tether, but less so and maybe more to DAI or what ever the flavor of the month is.

Then, the price is low enough and some company tweets something and the Matrix is reborn and everything old is new again. And someone, somewhere, who is currently just ignoring the whole Crypto thing, will limp in and at some point, discover Tether, do some research and report about it.

As I then read the headline on HN, I shall gaze out the broken window and take in, one last time, the burning remnants of a once thriving civilization. And smile.
I've gone through a similar experience. I like the other concepts in keyboards like Ergodox/Moonlander etc., but as far as actual key-press-feel, none of these enthusiast keyboards come close to e.g. macbook keys.

I think my ideal keyboard would be something like the Moonlander + the keys on the new macbook: a little bit of a click but basically zero travel.

I'd love to know why the Scots had legends that we came from Scythia (of all places) via Spain and Ireland!

"They journeyed from Greater Scythia by way of the Tyrrhenian Sea and the Pillars of Hercules, and dwelt for a long course of time in Spain among the most savage tribes, but nowhere could they be subdued by any race, however barbarous."

Not yet, because the cake is still growing. Wait until the cake has reached its peak size and starts shrinking (not for a short intermediate timeframe like 2017-2020, but for a timeframe long enough to consider it "the end game" for humans with finite lifespans) and see whether your assumption is still true then.

The problem will be that realizing that we're finally in the "cake-shrinking" phase will only be possible after watching it shrink for decades.
> Do I trust an ECDSA signature more than I trust a nameless brick and mortar bank holding some corporate funds. Hell yes. Computational security. Hard laws of math. I'd rather not hold tether in general, but IMHO it is less at risk than funds in bank accounts. I know this might sound strange to you dear reader, but you may not have experienced a time where bank accounts got haircuts, or your bank started freezing your funds. You cannot trust a bank! Be your own bank!

People have a very short memory. Citizens of Europe/US are generally not concerned because they think their governments will back their promises. Citizens of less fortunate countries do not mind the risk of Tether/Bitcoin because they national central bank is riskier and more corrupt/scammy.
