There is some precedent for hacking ex-miner cards to route the video signal back to a motherboard output over the PCI bus:

With so many more of them out there, it'll be interesting to see if this becomes more of a thing. Alternatively, it's easy to imagine that depending on just how constrained these are, they might eventually find homes doing non-crypto headless DC workloads, such as deep learning stuff.
> Just make them slightly cheaper per hash and voila

The problem is they want the mining cards to be more expensive per hash.

No, the whole setup looks dystopian to me. The presentation too knowing Google. Looks like a prison.

People are already depressed as hell from the lack of touch, real family, community and friends in modern society.

That said, of course this tech could have its uses, but mediated by the largest corporations on Earth that collect, sell and mediate everything about you and your friends? No thanks!

How so? Isn't there a link to types of alcohol use and depression(and cancer, and diminished mental capacity, and early death)? It's not like alcohol companies are being sued out of existence.

Realistically I think that it just so happens that the people who would work at facebook are the people who naturally don't believe that facebook is a force of badness in the world because their worldview already aligned with facebook before they joined.
> Also, like regular graphics cards, newer versions are highly prized so one might say that graphics cards as an industry is already all about e-waste. Unless you’d like to buy my Radeon 9800 or my GTX 1070? They’re still perfectly good for gaming… except everybody wants the new RTX ray tracing etc.

This is highly inaccurate, particularly on the used market. People want cards that can handle whatever games they play within their budget. A lot of older cards run tons of games quite well still, especially if you accept lower framerates / resolutions.

RTX in particular isn't actually that coveted by gamers from what I've seen. It's seen as a nice-to-have at best.
> I don't want to doubt we will find some use for more energy but... I think I have all the energy I need to be honest.

Not quite. You have more than enough energy for what you could imagine using it for. But I guarantee you that a greater abundance of cheap energy will create new uses for that energy. That's how its worked for the entire of human history.

The amount of energy we're talking about here is mind-boggling, almost incomprehensible.

Typically we talk about this in the Kardashev scale (and usually the Sagan normalized variant). The short version of this is that:

- A Kardashev-1 (K1) civilization uses all the energy out planet collects from the Sun, estimated at around 10"16 Watts;

- A K2 civilization uses all the energy output by the Sun, estimated at 10^26W

- A K3 civilization uses all the energy produced by the stars in our galaxy, estimated at 10^36W.

We are roughly a K0.6-0.7 civilization on this scale. Human energy consumption I believe is estimated at 10"11W.

So a K2 civilization has access to 1 million billion times what we have now. It's like if every person on Earth had access to 140 million times the Earth's energy usage.

> Everyone except market speculators

And debtors. The very notion of taking out a loan for something becomes nigh impossible with a deflationary currency, particularly one as deflationary as Bitcoin. Seeing as how the lower and middle class tend to take out loans for all sorts of reasons (since if they had the sort of cash lying around to buy homes and cars and appliances and such outright, they probably would be neither lower nor middle class), the direct harm such a currency would have is readily apparent.
Since these continents provide more than just websites; they provide mobile (iOS and Android) and other services, I think the original title is apropos ...

>Is that because the mined blocks themselves are still valid (i.e. the hashes check out), regardless of the presence of an attacker?

Yes. A censorship attack is just that - it's about mining valid blocks that ignore transactions from a certain party, and/or ignoring blocks from other block producers.

> But then how does it help the attacker in an economical sense?

If an attacker has 60% and censors all other block producers (40%), those other block producers won't be able to earn any mining rewards because teh 60% can continuously orphan the blocks they produce, putting them on non-longest-chain (invalid) forks.

In writing my last reply I forgot that difficulty adjustment only happens every 14 days (I can't remember how long it is with Ethereum's PoW, but let's take Bitcoin's PoW as an example), so it's likely that the attacker wouldn't earn any more mining rewards than an honest miner at first.

When that difficulty adjustment happens though, if the miner had been censoring for a good part of the past 14 days, the network would adjust to "consider their 60% the entire hashrate of the network", thus the attacker would start earning the other 40% of rewards for themselves in addition to the rewards they are supposed to earn.

> Doesn't the rest of the network know that the new 51% blocks are tainted, so to speak?

It becomes a very messy, subjective problem. For every block, you would have to prove whether the block producer is part of the censorship attack or just has an incomplete view of the network, which is an intractable computing problem without some sort of subjective heuristic requiring multiple network viewpoints and trusted parties.

There are so many variables involved, once you start listening, the schedule will never be a schedule again.

Sometimes I want to sleep a few extra hours. Sometimes I'm so excited for the day, I get up early and go to sleep late. Sometimes I need to stay up for a while, and next time I sleep it's for 20 hours straight. Sometimes it's just a nap here and there for a few days.

The most important thing I've learned is to listen to my tiredness level, and not get too carried away with productivity.

I'd actually attribute that to the technical inaccessibility of the internet meaning that, while not everyone on the internet at that point was smart, they were almost all curious about new things. The user base of the early internet was basically self-selected to be quite full of skeptics.
I spent years campaigning on this issue, and I fundamentally don't think that this broad argument will work against measures that encryption opponents are likely to propose today.

There was certainly a time when governments opposed availability to the general public of transport encryption and VPNs. Some outliers still do, especially the PRC (when the other endpoint is outside the national territory).

But this isn't a mainstream position of governments in liberal democracies today. They generally accept and even promote the use and availability of encryption technology for transport encryption, authentication, and digital signatures. (Some of this may be due to political calculation either in the sense of "it would be too hard to successfully restrict these applications" or "we've decided we think the positives outweigh the negatives".) The remaining campaigns are mostly about device encryption and about end-to-end encryption for messaging.

Government agencies campaigning about those mostly think that app stores and software distribution are centralized enough that they could enforce backdoor/exceptional access rules against a few large technology companies and cover the huge majority of civilian applications. It doesn't feel like they're wrong about that these days, does it?

(Some recent laws which have already been enacted in certain jurisdictions only kick in when a company has a specified number of users in a particular territory. The enforcement mechanism is typically fines or blocking, or in some cases the threat of arrest of local company representatives, who may also be explicitly required to exist.)
Yea, I asked because ability to lucid dream (and remember those dreams) is closely tied to a high working memory. A good test for working memory is called "dual n-back".

But that’s not what they’re doing. They’re simply limiting the hash rate. You can still run mining software, it just won’t be very good at it.
SF is more accepting of alternative lifestyle and personal choices (not just LGBT+).

NY is more direct, and in a sense, more seemingly trustworthy. SF, you often get vague, awkward, meandering intimations rather than honesty.

In SF, most people are either extremely boring, unreasonable, or have repulsive attitudes. (In NY and SF, they're often Seinfeldian.)

In SF, unless a guy is a model, he should go MGTOW because they'd just be wasting their time with swiping apps that only focus on looks (80% of men are ugly according to women), pedigree, and fruitless clamoring for attention.

SF and NY both have art, but NY has Broadway and book publishing.

Large companies operate almost entirely on legacy inefficient crap. It's often the case that the thing that makes them the most money is running on giant old barely-supported piles of shit.

People constantly underestimate the fact that >80% of the cost of software is maintenance. Upgrades and patches and redesigns/refactors and following modern conventions costs 4x more than the cost it took to build it. But nobody puts that in their budget. And then later people find this huge pile of legacy shit, and think, wow, this company really screwed up. But in fact this is totally normal.

By the way, this is the case because of how we develop software and hardware, not because they are some inscrutable element that can't possibly be built once and maintained for a lifetime (like, say, a building). We just don't build it to last.

"This reduced hash rate only applies to newly manufactured cards with the LHR identifier and not to cards already purchased."

I think you got that, but just to be super clear that is the case.

No need to be angry as far as I understand that's how chips are made nowadays. You can have wildly different consumer offerings on the same die.

You buy 3 inflated balloons, seller takes five of them and while you are watching pops 2. "Did you really have to do that"? In chip manufacturing this makes a lot of sense. Your anger is basically towards a manufacturing process and naming not the end product. And the process is just highly optimized while naming keeps thing pretty transparent - it wouldn't look good if they tried to sell it as a completely new card.

This is a 3D monitor. Not a light field display like Starline.

The traditional glasses free 3d monitors rely on special coatings on the glass to "split" the direction of a pixel. Some coatings are electronically controlled (like Sony's), some are physical (lenticular filters) It still displays a 2D projection of a 3D image, but twice.

By contrast, my understanding is lightfield displays projects the entire volume. So you don't have a pixel, you have a voxel. So each eye gets a different bit of the same voxel

Should the anti-slavery campaigners of the 1800s receive no admiration, despite social norms at the time, because vocal opposition to slavery "should be the bare minimum"?

What about companies now that go out of their way to make sure none of the workers in their supply chain are exploited? That should be the bare minimum - should we ignore the effort that they've gone to?

What about a family member who's been clean from drugs for 10 years? Should we celebrate with them, or just ignore their achievement because not being addicted to drugs is pretty much considered the bare minimum by broader society?
That much? Dang.
This recursion concern is a theoretical one.

It's exceedingly rare in practice for the short float to exceed the public float, and there's an inbuilt negative feedback which stops this from happening. The larger the short float %, the lower EV shorting becomes, ceteris paribus, and eventually the marginal benefit becomes negative and no rational actor would add to a short. That's one of the reasons (among others) why we almost never see a short float above 100% of the public float.

Additional regulations aren't needed for this, because it's not a problem.
Yes I know.

> The best UI is usually as little as you can get away with

I think this is what designers honestly believe, and obviously you do too. I just don't think it's true. I know that undiscoverable UIs have been a trend for a while now, and I wonder how much damage they have done to human productivity and the reputation of software developers in general.

It's possible your goal is to make an intentionally difficult-to-use app, so that people are forced to learn the tricks and secrets, and then eventually feel "invested" in the app after they have done so, making it less likely for them to switch. Snapchat does this.

But this is a photography app, not a trendy social network for Generation Z, and so the decision to make it intentionally hide UI controls from you is, in my opinion, completely crazy.
That may be the average, but it happens in spurts, and you can probably get some decent measurements if you put your mind to it.
Joel, I wish you'd stop appearing in every popular Elixir post's comments to say something bad about the language or ecosystem. You've admitted in previous discussions that you've never even used Elixir, so why even comment on a post asking about personal development experiences with the language?

>It got most of its (now faded) hype by trashing Ruby, which rubbed me the wrong way.

It's a programming language, not a sports team. Developers excited about a new language are allowed to be excited and compare with other languages. I don't know what trashing you saw that offended you, but commenting on every HN post to try to steer people away is unproductive.
Well, I guess I'll take down the DO referral link on my website and maybe consider moving everything back to Linode. I don't have anywhere near the referrals you do, but if all of my pending referrals went through I don't think I could spend it all within a year. I suppose this is a good reason to always prefer referral and affiliate programs that offer cash payments instead.

Not exactly, but it can be used to prevent you from running custom firmwares or reversing an update. On the Switch, each update would burn a physical fuse on the board, giving the OS a reliable way to determine what the latest update that Switch received was. Prior firmwares cannot be booted on a device with too many fuses burned, which is why the "1.0.0 Nintendo Switch" is going to become an increasingly hot commodity in the coming years.
I think this has evolved to be correct with how corporate stewardship has evolved since the 70's. I don't think it would have ever been responsible to shareholders for them to openly support the study. It'd be nice if they kept their mouth shut, but honestly in the modern world everyone needs to have an opinion on everything so.

Actually yes, I completely agree with you even though it's depressing. Calling it "inconclusive" is probably the least offensive response they could've executed.
> And if you peg your money to fiat, aren't you just ending up back where you started?

Not if you are talking about the idea that only crypto allows you to transact without a middleman and without the risk of having your funds seized or your account canceled.

But if you are simply talking about crypto as an way to invest: I can tell where I can park USDC and DAI and get 2% returns per month - and have gotten that consistently for the last 8 months. Can you tell me any traditional bank that can offer this good of a deal?

That's a clear strawman. There's a big difference between no privacy at all, and no privacy only in those cases requiring government investigation. There are also restrictions of police investigations by law, requiring warrant, and other stuff that are the real way you're supposed to be protected from the government.

The real problem is that while some western government have rule of law and can be relatively expected to be just, other governments are not, and it's bad setting the precedent of government intervention because many non western governments can't be trusted with it.
This is cheating! ;-)

I would say it's more a commentary on the fact the the gradient is effectively based on L2 distance in parameter space, and so can be a bad/inefficent direction to move in even if you have access to the full gradient. Hence the motivation for momentum and second-order optimization.
I mean, what’s your plan at that point? Move to the wild with a gun and hunt something for food? We can’t separate ourselves from society, and many countries have a way to reform and defend the direction their government is heading. That’s what we should strive to do.
Apple and Microsoft have also been removing support for PostScript fonts, so this is not just Adobe making this move. The entire tech industry is moving away from this old tech. I won't be surprised if support for EPS files (embedded postscript) gets dropped eventually.

> When I want to see people in person, it's not because of a lack of stereoscopy.

Of course, I'm not saying this will replace physical communication (I should've said "simulating" instead of "replicating"). But it's a clear step forward for traditional teleconferencing solutions. What do you think is the next leap from 2D video and displays? We're at the point of diminishing returns as far as increasing resolution goes, most consumers don't have a need for 8K or higher res displays. VR/AR is chugging along, but we're still a few generations away from mass market adoption.

> I'd add that the telephone was not only a very successful technology for a century, audio calls still remain very popular.

I don't understand. Video calls were never meant to replace audio calls, they just added a new sensory experience. It's perfectly fine for both technologies to co-exist for different moments and preferences. In a similar way this 3D approach is an extension to traditional 2D video conferencing if people have the equipment and prefer it. Judging by the expressions of the people in the demo and some of the comments here, you're underestimating how impactful this could be, especially if it's polished and cheap enough.
You can do that by buying gold, or frankly buying any stock on the market.
Nope. It seems to be working just fine to spur discussion and though. The replacement seems much less useful.

The fact that some of the factors may be close to 1.0 or may be unknowable directly is not a bug.
