> It is not a waste, as it provides physical security, exactly the same as idle nuclear missiles on standby do, or standing armies that are "doing nothing", until a war happens.

You don't think those get very wasteful in the real world? And there's no equivalent to a real war situation. You can set it up so you don't need to defend against the equivalent of enemy armies.

> The vast majority of mining today uses sustainable energy (70%+), because it is actually cheaper.

What kind of sustainable?

When miners locate next to hydro, and buy it up, that doesn't help anything. That hydro could have been sold as somewhat less cheap power elsewhere, after going over long wires, and then it would have reduced the load on coal plants.

Miners that eat up excess solar can theoretically do a lot to encourage the installation of solar, but they need to be happy letting their machines be turned off a large fraction of the time. If it's still profitable to run 20 hours a day, then they're still encouraging fossil power plants.

> Dishwashers and heated swimming pools use WAY more energy globally, but because pleasant luxuries are quite enjoyable, nobody seems to attack them.

Dishwashers are better than hand-washing, aren't they? Having plates is a lot more important than running cryptocurrencies in a particular way.

If heated swimming pools use that much, then sure let's go after that and use some kind of billing or taxes so they pay extra and encourage sustainable power sources.
Huh. Some variation of this house exists on any given block in my city except maybe the neighborhoods where the prices are well over $2 million. No HOAs. I guess my threshold for “annoying neighbor” is a bit different from yours.
Although I agree with your point. And even I personally perceive virus as something more like machine. But your analogy opened another interpretation for me.

Person probably won't burn their house down. But some may argue that people in fact do not have problem to burn whole planet down. Like virus with the whole organism. It may be just matter of focus.

I don't think of people like I do with virus. Just that analogy opened this train of thought for me. Several different interpretations is natural feature of analogies.

Ground planes are not only for high speed, the EMI performance of going 4-layers is easily one of the cheapest gains to be made in modern electronics. The other gain in this scenario is that you could tighten up the rebound times, which reduces input latency.

Can you pull it of with two layers? Yes, of course, but if you are charging $1000 for the thing I expect you to go 4 layers.

Anyway I messaged the chick and she told me to download this app and I signed up and it made me scan my ID and my face which I thought was wack again but trusted my buddy… So i end up sending this chick $200 in bitcoin like a f%c^in idiot, but then shes trying to say I need to send another $300 to be able to actually ‘process’ and I was like uhhhh nope? Now ‘she’ is trying to get me to do some two factor authentication confirmation code shit to ‘get my payout’. What I think is going on is they got into my friends account and made a deepfake from the face scan and started DMing other people. "

> Because they don't have the skill of drawing well. That's a trainable skill that is separate from being able to visualize things.

I'm not good at drawing and I have been suffering(?) from some degree of Aphantasia but I can assure you that none of the bicycles in that art project would be mine because I know my objects.

I can still probably disassemble and assemble my rifle blindfolded. I can draw it but if I try to visualize it in my head I only get a very vague picture of my room at boot camp and I feel it more than I see it.

Actually the images I can reproduce to so degree are the ones I've seen unusually often:

- my driveway

- my kitchen

- but most of all photos from my albums.

I don't dream much either but this summer I did some experiments, trying to sleep as much as possible each night (ended up with an average of 7 or something) and during that time I dreamt and also felt I was able to visualize slightly better.
I live with someone who has Aphantasia, when they recall their dreams it's in the form of 'words', not images. They have no concept of 'visual dreams'.

What do you mean by "allowed to"? In a PoW system, the PoW is a distributed timekeeping device. That's the actual operation the PoW does, and the distributed timekeeping is then what you can build a blockchain on. PoS doesn't not do distributed timekeeping. If you sign a block now, then go back later and sign a different block with the same key, there's no distributed clock that can be used to prove which was actually signed first.

The obvious argument here is "the one that was signed first will then have other blocks built on top of it". But since there's no PoW, building a parallel blockchain is trivial to compute, the only restriction is being able to produce something that's actually convincing enough. That and having people say "well, I was there at the time and I saw a different block than this", but that's just relying on authority rather than something that can be proven within the system.

Basically, PoS requires something external to the system to prove that history hasn't been changed. PoW technically does too, but what it relies on is "physics" and "provable historical fact" (i.e. approximate computing power available in the past).

You certainly can build a system that depends on something external to itself to ensure its consistency, but this challenges its claim to being "decentralized" and limits the amount of trust you can place in the system (and consequently the power of what it can do).
> make the numbers dance in your head

That is the best description of mental arithmetic I’ve heard, I love it.

Thinking about it, I guess I solve problems by moving numbers into certain positions relative to each other based on the operations then watch them split apart/combine, grow/shrink, etc. I always assumed it was a weakness in my math skills but the dance metaphor is a profound reframing, thanks!
Ask HN: How do you keep track of your reading queue (books)?
I usually have about 20+ books in my open reading queue at any given time, on various formats and devices, from paperbacks to eBooks and PDFs. There are entire collections I intend to read thoroughly and completely in my lifetime, like the European classics and the Western Canon, and then there are other books which I quickly pick up and discard or peruse for value (like Tyler Cowen's method of reading fast)[1].

I would like a simple app or workflow to keep track of reading progress across all my books. Maybe academic papers and articles as well. It should offer quick progress percentages at a glance, perhaps even an iOS widget, and be quick to input new books and update reading progress.

I've tried the iOS apps "https://readinglist.app", "http://leio.co" and Bookly, currently using ReadingList.app and am pretty happy, but would love to hear what you guys are using.

KVM maintainer here, is there a report of the EFAULT issue with AMD processors?
I think you and I have different bars for what “expensive” means.

Manufacturing things is expensive because of the fixed costs. To make it cheaper you need to make enough sets to dilute the fixed cost among N buyers. If at N=20 the price is already something people will pay, that’s not expensive IMO.

The problem is that the case doesn’t work that way, because the costs of machined aluminium are pretty much linear with N.

LPL makes things look easy, I'm sure they aren't.
PoW at least provides a decent and somewhat fair coin distribution mechanism.

With PoS, the coin creators can assign themselves an arbitrary fraction of the coins, concentrating the wealth. Even if there is a public record of all the funds raised in a public sale and all expenditures made (which is rarely the case), it's possible for the creators to participate in the public sale and recover large parts of funds used to buy their own token by generous expenditures on software development and such.

Fusion if we can crack it, totally. Seems like a clear winner. Fission probably will if there's some political will behind it, but not unless there's a change in sentiment.

Those two examples were demonstrating what happens when you don't have provable consensus. They weren't issues with the validity of the blockchain, but debates over changing the software itself. They're good examples of why centralized development of a decentralized protocol still opens up the software to attacks (though with the option of continuing the blockchain without the software change, as Ethereum Classic did for a while), and demonstrates why having a provable consensus mechanism is important.

Hi great friend! let's connect! info for dms in my profile.
The revolutionary bit is you can raise money through a DAO without paying millions to a corrupt investment bank to handle your IPO. No letting the investment bank set the opening price too low so their stable of institutional investors get a reliable "pop", etc. You don't need to spend millions on special consultants to help you prepare regulatory filings. So far, anyway. I'm a major crypto skeptic, but I definitely see the appeal of disposing of these gatekeepers and putting the public back in public markets.

I don't agree that locks are "just" a social contract. If they were, the most simple and cheap lock would be sufficient for everything. They are a social contract, but they are also for theft prevention. Those people that are determined to take something from you don't care about that contract and you need as good lock as possible to make it hard for them.

You’ve just went full circle and invented central banks.

Or maybe we just don't have a good understanding of how to learn it (and/or most people don't try). I can't visualise anything but the briefest of fuzzy flashes, and I'd love to learn, but I have no real idea how and not sure I'd invest enough time into it if I did because most of the time it doesn't affect me, so I'd "love to learn" the same way I'd "love to learn" better French (he says while 2 days overdue with his Anki deck) - it's an aspiration that often falls flat in the face of having to invest time.
More then that. Academia is hyper competitive. It is kind of pyramid with huge amount of smart hard working people falling out on every level.

So the "double-standard on HN" is that not literally everybody hates TikTok, and the existence of positive comments counts as TikTok and Twitter not getting criticized, despite there being many comments criticizing them? really?

Just for contrast, this is how the second-highest top-level comment starts:

But evil HN is always only criticizing Facebook and letting TikTok get away with everything, sure.
> I had a locksmith out a couple of years ago, and was very disappointed when he simply got out a drill rather than starting with 'click out of one'.

That’s a common occurrence because of the incentives. The locksmith wants to spend as little time as possible (average time), and doesn’t pay a premium for destroying the lock, since most people don’t confront them on that.

LPL is amazing, but any decent locksmith could get at least near enough him in competence. It’s not that it’s so hard that very little people can do it, it’s that is very niche for most people to learn.

I never got “good at math” because not only is the symbology dense, it’s incredibly hard to find definitions. I’m pretty good at teaching myself new things from books and papers. But I just can’t grok math. Math on Wikipedia is a nightmare. It makes me sad because it’s unnecessary. It doesn’t actually have to be so hard.
