"can you demonstrate one?"

Blockchain is just bookkeeping. I don't know, can you demonstrate a use case for accounting or book keeping?

Up to now we always had to do accounting in books that can be cooked and have to be trusted.

Blockchain is accounting with books that can't be cooked and don't have to be trusted.

It has other problems which are real, but so what? Everything has some kind of problem.

With blockchain the problem is if you go for convenience and use a centralizing key custodian, then someone else controls your keys and everything they protect, and if you don't, then it's too easy to lose your keys and everything they protected with no recovery.

Well those are real problems but they are no different from the problems of using a plain database that can be copied, modified, hidden, stolen, has to be trusted even though you know you actually can't trust the owner, etc...

"it" = some type of linked list. You can have the truth table, for example, for an "AND" gate be statically defined as 4 cells each for every possible result in the list (like 1 and 1 is 1, 1 and 0 is 0 etc). So when there's 1 and 1 in the input cells, the linked cell storing 1 is selected: basic if, else logic.
Sort of, if all possible results of basic logic operations would be statically stored on an SSD, and the emulator would just select the needed one based in inputs. And these inputs could be just a data array stored in another place on an SSD.
I am not asking myself why this hasn't just miraculously happened, but am sure that if enough physical logic elements of an SSD are emulated, this may provide venue for emulating basic computational operations.
> If you look at the progress in pesticide free organic farming and indoor/vertical farming

By what measure is vertical farming more efficient?.
I've heard the contrary regarding green house gas emissions, it is still less efficient in most crops, it consumes too much power and that overcompensates any efficiency gained in other areas

It's interesting that this conclusion can change drastically if electricity becomes 10-100x more efficient
> No real guarantees around RVO / NRVO

Shouldn’t Rust in theory have a lot more freedom in defining its calling conventions than C++ has? I wonder if there’s anything that prevents doing RVO by default, or if just hadn’t been a priority yet.
Point taken (and agreed), but it doesn't really. A boolean logic isn't going to get you sequential circuits, for example. You need recursion for that.

Because I've seen it even in places where the guy doing the hiring was the major share holder. He flat out told me that no one would pay a salary like what I was asking. It went downhill from there and he didn't take it well when I told him I was making more than that now and I figured this was going to be a relaxing year to wind down from my current position, hence why I was asking for less.

There is also something to be said about nudging developer on the "right" way to do stuff.

Perl is not only hard to read because there are many shortcuts that might look like line noise for the inexperienced (hell, Rust have a bunch of those too), it's because there is a bunch of the ways to do anything.

Like take humble array

Perl> @a
$VAR1 = 1;
$VAR2 = 2;
$VAR3 = 3;
$VAR4 = 4;
$VAR5 = 5;

Perl> @a + 2
$VAR1 = 7;

Why adding a number to array results in number ? Because array in scalar context returns its length. It leads to some very compact code

if (@a > 3) {print "big array"}

but, uh, what you do if you want to see length of string ? well length($string).

Will that also work for arrays ? Nope, if you want to force scalar context you're supposed to do scalar(@array). So how to add 2 arrays ?

@c = (@a, @b) #

obviously. But wait, what we really typed after variable expansion is ((1,2),(2,3)) and in other languages

irb(main):001:0> a = [1,2]
=> [1, 2]
irb(main):002:0> b=[2,3]
=> [2, 3]
irb(main):003:0> c = [a,b]
=> [[1, 2], [2, 3]]

>>> a = [1,2]
>>> b = [2,3]
>>> c = [a,b]
>>> c
[[1, 2], [2, 3]]

that's exactly what we get. Confusing ? Sure. But it saves few characters!

I'm all for people being able to opt out of paying all taxes, as long as society is free to opt out of all dealings with those who choose to do so, including being free to refuse them access to use any publicly financed facilities, including roads, and the ability to refuse to trade with them.
There’s actually a huge volume of research on spatial components mapping to memory. Check out the book: Moonwalking with Einstein for proper citations.
This is not about a heap-vs-stack tradeoff, this is about the compiler routinely generating very inefficient code that copies data around on stack for no good reason.

For an example I've seen myself: using a custom GC pointer library, calling `Gc::allocate(SomeBigStruct{...})` constructed the SomeBigStruct on stack and copied it around using memcpy 4 times before it actually landed in the allocated heap memory. The equivalent code compiled with a C++ compiler would have probably optimized the program enough to fill the struct in-place on heap without any issues.

(this example is from over a year ago; it's not as bad anymore, but it still generates suboptimal assembly with too much copying)
> - buyers and sellers (trade) create markets.

Nope, markets are created by governments.

> - Taxation can happen via either currency or goods.

It's true that many early currencies are named after some commodity (shekel being a good example) because governments imposed a tax in a commodity and that then became the unit of account. It's the same principle though.

> - Governments manage societies, most happen to fund themselves via taxes.

Taxation is the sole means by which a government provisions resources away from the private sector, and to the public sector, unless your society is simple enough that you can run it without money (which is a pretty small society).

> I'm not sure what you mean by public purpose.

Things that we get by dint of belonging to a society, such as schooling and libraries.
I think it’s still worth being critical of individuals even if they follow all the rules. The super rich have the largest influence on society as a whole. They cast a vote on the status quo by endorsing anti-social policies with their actions. Just because something is legal doesn’t make it right. I’m not arguing any particular consequences etc. whatever. I also agree that ‘news’ which emphasises a misleading causality is not helpful.

Nevertheless, the super rich ‘legally’ avoiding the proportional contribution to society nominally expected of them _because they can_ is still anti-social behaviour and however the laws came to be is irrelevant in my opinion. Democracy is so flawed especially at the individual policy level I consider the argument that ‘the populace voted for this’ conservative in the worst most nebulous way, defending the status quo for no reason other than it is the status quo.

Of course policies that protect the super rich are beyond the normal reach of democracy because lobbying and donations are so prevalent.

Do we approve of this behaviour in a normative sense? That seems like a more important thing to keep in mind than if individual’s playing of the game is technically above board. Or how the rules came about. To me the details of the case amount to details of a symptom and what is of more interest is the underlying condition which is revealed.

FWIW I don’t know the details of the case I’m just trying to nudge the discourse in a direction I find more interesting.
You may think you're being well meaning but you aren't Maersk and can't speak for them. Maersk believes it's an advantage to them to use a blockchain. Maybe we ought to ask Maersk why they chose it.

Everything I read in this thread is dripping with vehemence, hate, ridicule, or certitude (your I haven't seen a demonstrable use case in 15 years).

If the kind of echo chamber you want to build is the one where you've won and any even smallest proffering of a tilt toward blockchain as useful is crushed congratulations you're doing it: nobody who even wants to give one inch to blockchain will come around here. When I try and point out one useful thing is a blockchain, oh that thing is a different kind of blockchain. It's astounding the mental acrobatics people will go to to stand victors over their tiny corner of the internet.

This is frankly culty, repressive behavior that's not at all in the spirit of curiosity.

> How about... they, and everybody else around the world, should work hard for good governance for all people of Earth?

Yup. The remote worker visa application was simple enough (I'm self employed). I live in a nice apartment in Tartu for 800 euros, 40 for internet, 30-100 for utilities, 70ish for health insurance. I've got a gym, store and pizza place within a few blocks. Most people speak some English. Estonians definitely look grumpy (no offense), but generally lighten up when they realize they're dealing with a clueless American.

My main complaint is that the remote worker visa gives you the right to stay in Estonia...and nothing else. You don't get an Estonian ID which is necessary for all sorts of things like setting up internet, getting a local phone number, or getting books from the library, and you can't get a bank account to pay your rent. LHV, Coop and SEB all claimed I could open an account with just my passport and lease agreement, but denied my application (after paying several hundred in application fees). The e-resident card is basically useless.

The tax situation is unclear. You become a tax resident when you stay over 183 days. But all US citizens are tax residents of the USA, so the USA-Estonian tax treaty kicks in with its tie breaker rules. Because I have a house in the USA, it means I would be treated only as a tax resident of the USA, so I would only pay taxes there...I think? But I can't imagine why Estonia would offer this visa program if they weren't getting something out of it.

Steel usage is on the order of 100,000t for a GW of nuclear reactor and a decent chunk is rebar rather than low alloy stainless. If we take it on the high end, that's about $200 million. Double it for finance costs and you're around half a billion. Stainless and heavy fabrication costs more, but that's not 'steel costs' per se.

Over its lifetime a NPP including fuel and upkeep is on the order of 20 billion/GW.

Might call it 5-10% at a stretch. Certainly not enough to double it. And if nuscale reactors are claiming to be much cheaper and less resource intensive then they're either lying about the steel costs being the cause, lying about hidden subsidies, or lying about using an order of magnitude more steel. Either way you probably don't want scam artists in charge of enriched uranium.
Also, Spain has a wealth tax outside of Madrid, which may or may not apply based on your financial situation, but it’s significant if it applies to you (1-2.5% of net worth annually).
> I’ve got to figure out if it’s really John Doe and that’s a bit of work if I don’t already have John’s public key.

Maybe a dumb question, but assuming a scenario where you have a concept of "really John Doe", isn't there always some authoritative source on what that means that you could use to obtain John's public key (whether that's some user registry, direct contact with John, etc)?
All you need to pull this off is ground-floor access to a unicorn startup. The IRA rules are the minor term here.

Anyone could, provided they had an investment that gained as much as Thiel’s, do this.

Maybe there should be lifetime caps on tax protected withdrawals to prevent this kind of edge case, but that’s not how the laws were written.

There are other ways for wealthy to dodge taxes. Invest, borrow, die works slightly worse since you’re paying loan interest instead of capital gains taxes. But it’s still not paying taxes.

So yes, this is kind of interesting, but not that much more effective than the current tax dodging strategies.

I am with your neighbor, I hate dogs left alone which annoy all neighbors with constant barking, while their owner doesn't have to listen to it. It's less of an problem in the house, but huge problem in residential apartment building, so obviously you call cops to annoy neighbor to force him to do soemthing about it by police harassing him, not that because you would genuinely think there is animal in distress. If your dog barks at everyone passing around your house, there is something wrong with your dog and you raising it. If you can't take care of dog and raise it properly, don't get one.

After first diagnosis, under the care of a psychiatrist, I went though a typical escalation over a couple years to reach 80 mg Vyvanse + 15 mg of Dexedrine per day. 50 + 10 at ~5AM and 30 + 5 at ~noon. That's about 40 mg of dextroamphetamine per day. I enjoyed the euphoria but never experienced dependence except in the sense that I became attached to functioning like my neurotypical colleagues. My psychiatrist's professional opinion was that some people required fairly high doses and the therapeutic benefit at those doses would stabilize long-term. I will note that he was reasonably diligent in ongoing blood tests and monitoring my health, etc.

A combination of factors made me decide to stop taking Vyvanse: a probably unrelated health issue, 40 mg of dextroamphetamine per day gave me unpleasant physical side effects, and my realization that 5 years of medication had profoundly hanged my habits and self-concept. I decided to see if I could go off meds and sustain the benefits. So I tapered off (no dependence!) and for 6 years I relied on habits, strategies, exercise, nutrition, healthy sleep and meditation.

But I am now taking Vyvanse again and there is no doubt in my mind now that no amount healthy living can do what Vyvanse does.

My current dosing: on a day to day basis, I take 0, 15, 30 or 45 mg of Vyvanse depending on what I need to get done, my energy level, and my habituation. I drink coffee with it because I find that caffeine helps me keep the Vyvanse dose lower. I organize my life to maximize the value of my medicated time. I experience a clear step function in executive functioning between "slightly too little" and "enough" Vyvanse and I can feel the gears shift in my head, takes about 5 seconds, as the drug concentration in my body crosses the threshold. I move the dose up and down in 15 mg steps and when reducing my dose I spend 2-3 days at each level to avoid crashing. I take Vyvanse holidays two to six weeks long, two or three times a year to reset my habituation and fix any sleep deficit. After a holiday I get the full therapeutic effect from 15 mg. My goal is to generate enough high-quality executive function hours to fulfil my responsibilities, but keep my dose as low as possible. It seems to be working so far.
This is how it starts... Roth IRAs have always been built on a flimsy promise: pay your taxes now, and pay no taxes later. I strongly suspect in the near future, those individuals that were responsible and actually saved for retirement will be seen as 'cheating the system's because they aren't paying taxes on their sizable Roth balance.

Articles that cherry pick a rare example to cause outrage are attempting to change the rules. Thiel played by the rules and got lucky with his Roth. That doesn't change the fundamental promise of the account.

Using AI to reality-check comment would be cool.

But if you're using comments to explain the code, 9/10 you just wrote it in too unreadable way.

Sure, some algorithms are complex enough that some comments are needed to explain the how (that's the 1/10) but in most cases the comments should explain why, not how. So instead it should be

// Add the calibrated skew to compensate for latency
x+=2;

or whatever is the reason for the code existence.

This sort of happened to me. At some point waaaay back I was clicking around gmail and figured out how to create a custom domain. But for some reason I didn't do it for myself, I did it for my mom. So for over a decade my mom had her own custom domain on gmail.

And by this point I don't even remember how I did that. But now Google emails me saying I can't do that unless I pay them, I need to have some sort of payment info or they'll close the account.

Fine, I migrated her over to proton quickly, helped her set it up and done. They just did the final close of the old account recently. They gave me plenty of time and warnings to solve this. Unfortunately whenever I tried to login with what I thought was the admin account, gmail just said it wasn't the admin account. So I really had no chance to investigate further.

> If you mine your personal connections you may find people you know or can get to know who are active in charitable activities abroad. I have several personal friends who run orphanages in third world countries.

This is what I mean. Orphans in third world countries are not your neighbors and the exact sorts of communities many EA charities are trying to help. It's just they want to ask the question "of all the orphanages in developing countries, which ones do the best job of improving the lives of the children under their care?".

> I think perhaps that if you are trying to find a way to fund good across the world you delegate it to a large organization that makes it very difficult to know if there is any actual impact or you can look around you and find a more personal connection that can give you more confidence in the impact you provide.

The whole point of EA is to create the accountability and visibility into the impact of these charities. The whole premise is that basically:

1. People in your local community may be struggling but there are almost certainly people much worse off in the developing world. Those people also suffer from problems that are so bad that you can make a huge difference in their lives with relatively (to us affluent westerners) small amount of money.

2. We should try and evaluate rigorously which charities are most effective at their stated goals and direct money there. Like measuring anything, it's difficult and uncertain but at least at the current margin we can still extract a lot of useful information this way.

And then there is a broader EA tenet which is that, if you are an affluent westerner, then you can almost certainly afford to give more money away to charitable causes. The reduction in your personal living standards will be minimal and you can make a massive difference for a lot of the world's most desperate people. And frankly a lot of the rest follows from that. Like if everyone in your community started giving 10% of their earnings to charity, is it really the case that the local food pantry would be able to use all of that money productively? Would any local charity be able to. At a certain level of giving you simply run out of opportunities to deploy the money locally and have to cast a wider net.
I mean to be fair, plenty of people would also chain and beat other humans if given the chance, as history has shown.
