> we accept with the presumption that no one would offer so much money if it weren't very important

That seems to be overthinking motivation.

If a sponsor was offering $500k for someone to stand on a streetcorner and sing Weird Al songs most people wouldn't consider that was an important job but they'd still do it for the money. Because the money provides opportunity to buy or do things that are worthwhile.

Money is a simple way of valuing objective time vs opportunity.

Mankind is currently in possession of a practical fusion technology.

It might be worthwhile to remember that Ivy-Mike fission-fusion technology worked the very first time it was tried in 1952. Mike technology was the basis of the first thermonuclear weapons in the US arsenal. Adapting Mike technology to be pure hybrid DT-DD fusion opens up many new applications in economical power generation.

In 60 years, no other fusion technology (Magnetic Confinement or Inertial Confinement) has ever produced any net energy (more energy out of the fusion reaction than it takes to get the fusion plasma to fusion conditions).

In 60 years, all existing MCF and ICF fusion systems have never worked (in the sense that they have not produced more energy from fusion than it took to get the fusion plasma to fusion conditions).

Mike fission-fusion technology worked the first time it was tried and produced huge amounts of net energy (and has never failed).

Rather than placing our faith in scaling laws while we build ever larger and more expensive Magnetic Confinement fusion experiments (tokamaks and stellarators) while trying to achieve break even energy generation -
why not go back to the field and adapt technology that has never failed to finally find success in fusion?

> except when I got to Iran and I got a "real job" with a driver and everything. But then that kind of blew up in my face when the revolution in 1979 came...

He left us hanging there! What kind of job can a 26 or 27-year-old American hippie traveler get in Iran, presumably not even speaking Persian, that comes with a driver and everything? There must be an interesting story there.

it's really interesting to have the option to make and use a money of your choosing instead of a state currency who's issuance is totally outside your control

democratization of money!
While I also question the necessity of having every single moment documented and framed, I don't think you or anyone else has the authority to decide what's worth capturing and what isn't.
The number says "a comfortable life". University life is not the entirety of a persons life. And these numbers are for the US anyway, where university isn't free, and that alone would cost you more than $10k/year... in fact, far more than $10k/year.

I think you need to revisit this in 10 or 20 years. I think you'll have a different opinion on this number.

$10k is not comfortable. That is poverty. And the question wasn't what is possible to survive on.
I think he's talking about the difference between correlation and causation.

You're right though in that from a law enforcement POV the two look roughly the same.

I think you missed the memo, racism is now just the act of identifying race as existing.
That’s not what that phrase means.

The question says "without thinking about finances again". It is true the number could be lower, but there does need to be some buffer here. Otherwise you're one mistake/accident/recession/layoff away from "thinking about finances again".

If this resonates at all with you, go get Alexander's four volume work 'The Nature of Order.' And stick with it. It's a lot of ground to cover. The goal, as always for him, is to be able to construct built environments with a timeless, life enhancing quality, and he spends volume one demonstrating that the quality is repeatable among individual observers and then constructing a system of analysis to let understand what drives repeatable observation.

Then volume two is about how you go about constructing environments with this quality. If you have a hard time, flip ahead to the sequence for constructing a Japanese tea house. Volume three is how you do this in practice, and how you set up the logistics and project management so it is possible. Volume four tries to construct a mindset which lets the approaches in volume three emerge as obvious behaviors.

Each is a step back: here is this desirable, repeatable quality; here is how you generate a state with this quality; here is how you generate systems that generate states with this quality; here is how you generate societies that generate such systems.

It's utterly brilliant. And I want to warn off everyone planning to translate it immediately to software. There are sequences of unfolding that we can develop and use (I've got some notes I've been working on), but the quality that we are trying to generate is not the same. The timeless, life supportingness that Alexander analyzes is driven utterly by Euclidean geometry. Software architecture is not. There is a quality that we are looking for and that, much more about melding invisibly into the domain and being adaptable as the domain adapts. I really think that the quality we're looking for is buried in relations among Wittgenstein's language games, not in geometry.

I also think we would benefit from looking a little further afield than just constructive sequences. He talks about the Tahitian canoe maker's chant which gives the order of unfolding of making a canoe. Let's compare that to the Epic of Lata, used by the sailors of the windward Solomon islands as their sailing instructions and protocol when sailing the alien looking Vaka o Lata (see http://vaka.org/). When they are embarked, they take the roles of characters in the epic and reenact the parts of it that correspond to what's going on. In the wonderful book 'How Buildings Learn' (if you like Alexander, you'll love that one), there are vernaculars documented of how traditional houses of various kinds expand in repeatable ways over their lifespan. Similarly, we spend more time adapting software and operating software than we do building software from scratch, so our unfoldings will need to be much more shaped by a vernacular driving how a system gets reshaped.

Mind you, I may just be sleepy and that rambling may be totally inconsequential and useless.
Quora is one of my top Internet destinations at the moment -- you can find anything from [why farmers don't use silos any more](https://www.quora.com/What-was-very-useful-when-it-first-cam...) to [true facts about Jeff Dean](https://www.quora.com/What-are-all-the-Jeff-Dean-facts?ch=99...) to [how to compensate salespeople](https://www.quora.com/What-should-a-CEO-know-when-he-designs...).

I don't care about getting my data out any more than I care about not having transcripts of the conversations I had last month.

What I do care about is that Quora lets people delete comments on their own answers, meaning they can just lie with no way of being shamed and there's no point contradicting them.
I’ve found ergorest forearm supports work, along with a keyboard without a number pad to reduce mouse reach.

I’ve swapped between various split keyboards over the years, starting with the beta version of the Microsoft Natural keyboard - sadly most of these have a number pad and that creates a mouse reach issue for some. These days I use a ten key less gaming keyboard.

Also small free weights to exercise arms frequently during the day at the desk seem to help.

The current title of this submission is "Screen Time Changes Structure of Kids' Brains, New NIH Study Data Shows." The current link is to https://www.nih.gov/news-events/news-releases/abcd-study-com... . (Related: I wish there were a log of this.)

The current link has the text, "For example, a recent study by ABCD investigators showed associations between differing amounts and kinds of screen time (e.g., video games vs. social media) and different structural brain characteristics, psychological traits, and cognitive function," linking to https://www.sciencedirect.com/science/article/pii/S105381191... a paper "Screen media activity and brain structure in youth: Evidence for diverse structural correlation networks from the ABCD study," whose abstract ends, "Taken together, these findings support the notion of [screen media activity] related maturational coupling or structural correlation networks in the brain and provides evidence that individual differences of these networks have mixed consequences for psychopathology and cognitive performance." It's unfortunately an Elsevier paper, but I think my alma mater still gives me access. Let me see what it says and try to summarize....

OK, I've read the article and it is hard for me to follow concrete observations and exactly how much change there is (probably because I'm not an expert in the field and it's also 2 AM here). If I'm reading it right, they did a "group factor analysis" using R to identify 4 hypothetical variables with nontrivial correlation between both their screen time survey questions and the brain measurements from the NIH ABCD study. They believe they found some correlation between more screen time in general and more "externalizing behavior," and also some between more gaming and more "fluid intelligence".

More interestingly, they caution, "First, this is a cross-sectional assessment, which enables establishment of associations but does not allow drawing causal inferences.Although multivariate methods such as [group factor analysis] enable differential examination of the impact of [social media activity] and structural brain characteristics on outcome variables, they cannot address the 'chicken and egg' question.Therefore, the longitudinal component of ABCD is essential to begin to delineate causal longitudinal pathways." (ABCD is a long-term study as these children grow; they did this paper based on a single snapshot of the data.) They also state, "This diversity of findings provides an important public health message, i.e. screen media activity is not simply 'bad for the brain' or 'bad for brain related functioning'."

So I think this is a real interesting paper, but deserves more study and more reporting on what's actually happening, and saying that screen time changes brains (as opposed to, say, kids who want to take their aggression out on something spend more time on the computer) is prematurely attributing causality.

Can you provide any examples? I literally cannot think of a single company that needed to do an ICO for reasons other than to make quick money. I’m actually far more skeptical orf ICOs and adding blockchains to a company for no reason than bitcoin as a mere currency solution. We don’t need an ICO and a blockchain to track bananas in Laos.
I think this is reasonable for the government to enforce until there is some 100% publicly accessible banking system that provides a medium of digital payments. As it stands, there are people who are shut-out of parts of the economy for one reason or another.

The dangers we will face (and why some people like the idea of bitcoin) is that we're developing dependence on a financial system entirely controlled by private entities. Your bank that holds your money, to the many companies digital payments flow through, to the bank where your money is going. You are controlled by scores you can't directly influence, and can't challenge. If you're Chex score is too low, banks will refuse to let you hold a bank account with them.

I think accepting cash should be required until we have a system like this in place (I'm US focused, but its the same for other countries): The USPS/Federal Reserve buys/launches a Visa/Mastercard like transaction network and at the same time providing a universal bank that any citizen could use without charge. This would make sure that there is no such thing as "un-banked" people, and would provide a world where we could realistically go "cashless."
Alexander himself agrees with you. The pattern language approach in his hands and in the hands of some architects was a tool that produced wonderful buildings. In many hands, the patterns were there and the buildings were still miserable. The patterns were necessary but not sufficient. I posted a comment elsewhere in the thread referring to his recent work, 'The Nature of Order', where he thinks, after forty years of work, that he's figured out the sufficient part as well.
That's a good point.

But not only is the rough observation of 'previous episodes of trauma causing seemingly irrelevant malaise and illness' interesting ... the methods is similar in some case as well.

For example, for soldiers with PTSD, one of the more beneficial therapies seems to be having a health professional help the soldier 'revisit' the experience. They do this over and over until there's less PTSD associated with the event.

This is remarkably similar to the process of 'auditing' in Scientology - at least in terms of discovering and revisiting points of trauma. They call it 'processing'.

As far as I am concerned they are the same thing, point blank.

But I also agree that Dianetics probably did not entirely originate this, rather making the point that this has been popularized already for some time.
Does anyone ever feel irritated by "amateur" produced videos that approach the quality of professional studios? Sometimes it's distracting when there's too much work done on the video, and you can tell there's additional people helping out behind the camera and you never get to see them as part of the video.

Basically amateur/gonzo level videos feel more truthful than the highly edited videos.

Lightning development is taking much longer than I had hoped. There are still some serious issues with the implementations. But what I miss most is focus on UX. If we ever hope for wide-spread adoption we need to start to focus on regular users: Offer nicely designed wallets, good UX, teach new users about how LN works during onboarding etc. The current generation of LN-wallets is poorly designed and often confusing, even knowledgeable about how lightning works. I was however positively surprised by https://lightningjoule.com/, it is going in the right direction (even though it's not a full wallet, just a UI for lnd).
That's very nice and I'll probably be using it a lot, after VS2019 will stabilize (it's just a preview now).

However, the fact that this thing works so well, says a lot about the design of C++ standard library. They should have encapsulated the pair of iterators into a single structure, and implement implicit casts from vectors/arrays to that object. Requiring to type begin/end every single time is counterproductive.
I hope so - I have been saying for a while, once I get to 10m, I'm going to quit working and start focusing on doing things to help other people. I figure 4% = 400k, take 200k and reinvest it, and take the other 200k and use it.

Its christmas time, I'd like to go to my local box store and buy out the lay-aways. Donate some hams and turkeys to the poor.

As long as I've done what I can to take care of myself and family, I think its important to start helping other people.

One of our big flaws in society is we try to categorize people too much. That leads to the wealthy looking down on others. Middle class looking down on others. The poor looking down upon who they can. It is not necessary. Once you have food, home, and some basic luxuries, all you need is to save for the retirement days.

Hello,

I am an extremely introverted person and I'm at a
point in my life where it's getting to be a really big
problem. So I am looking out for ways to deal with it.

I have been watching a couple of mini-clips of some
of Jordan Peterson's videos and I find them very useful.

So are there any resources available that you would
suggest for someone like me?
None of the countries look particularly good, because we're on a backwards trend globally. But US still looks better than pretty much everybody else.
The problem with this is that the bootloader is now becoming more and more locked down and the consumers have to jump ever more hoops to unlock it.

Some years ago I had Samsung S2 where unlocking the bootloader was an offline activity. I don't remember how but doing that was quick and easy. Now I own a MotoG4 where unlocking means going to some website, entering my email address and then receiving unlock code in my email. If Motorola knows my email address, or can link the (supposedly unique) unlock code to my phone, what's stopping them from voiding my warranty?

I have a hunch that newer versions of some mainstream phones do not allow unlocking the bootloader, and this is going to become more and more common.

This is one of those signals - among others - that China is farther along the next technology curve (whatever it will be) then the U.S. They basically skipped plastic and went straight to digital/mobile. If the next wave of startups coming out of China can crack international markets, like U.S. based startups have always done, then... look out.
Tell me about it. I was probably among the few thousands of Indians using the website during 2012-2013. It helped me so much with learning programming, asking experts, reading about their experiences about working on large scale projects. I thought Quora was the go-to place for useful advices.
A year or so and a Quora popularity boom later, I had hundreds of followers, feeds with all kinds of life stories and experiences, and all stuff I deemed useless. I decided to delete my account.
The shitloads of crap that Indians have spewed on Quora is most probably the only thing I feel shameful about as an Indian.

Eternal September.

https://en.wikipedia.org/wiki/Eternal_September

What happened in India was from mid-2016 usable internet access became super cheap. This suddenly added at least a hundred million new users to the Internet in a short span of time, people who were being exposed to totally new communities beyond their facebook friend circle. This is not about India, this happens whenever there is a clash between new users and old users and the number of new users is overwhelmingly larger than the old ones. This should have happened when China started getting internet, but I guess their government policies coupled with less number of English speakers than India prevented it. But this is not the last time this is happening. After the Indians settle down, I guess next will be Africa and we will start again.
With the concrete house in an hour, the idea is that the printing step takes 1 hour. The entire process would be performed in a massive temporary box, and an inert filler material would be placed at the same time as the concrete to fill voids and eliminate slumping. This would allow a second floor to be "printed" over the room voids below.

The printing step would be accomplished in 1 hour. The curing step could happen over a week if need be.
Nowhere have I said that $10K per year is comfortable. I have a dentist appointment tomorrow that I don't yet know how I am going to pay for. I can't remember the last time I got a Christmas or birthday present, or the last time I went on a holiday. It sucks, but there are people worse off than me. And there are three orders of magnitude between $10K and $10M. If anyone thinks they need $10M to feel secure and comfortable, than I honestly feel sorry for them. I think that's the kind of insecurity that would be very difficult to escape. Probably even harder to escape than poverty.

Again, I apologise if my comment/s seem impolite. I am not having a great day, but I don't mean to come across as disrespectful. I understand that I live in a different world to many of the people here on HN. I also think we may be talking past each other a little bit, using different definitions of "comfortable". I think it's possible that I don't know what comfortable is supposed to feel like, at least not the way most people here seem to be using the word. To me, comfortable is just having a loaf of bread in the cupboard, a roof over my head and a healthy body. I feel like that is all I need, and that's the point I was originally trying to make.

Perhaps not in the US, and perhaps not now. But the first thing that came to mind for me was the Hong Kong MTR, which started as an extremely successful statutory corporation that only later was privatized (and that with dubious results). Same with the Housing Authority in the same territory, which also was well-run until it was privatized and begun to sell off assets to private enterprises that turned the screws on renters.

There's also the more fundamental question of whether a public good like transit should (and can!) be run for profit and at the same time benefit the entire population and economy. It's possible that's only feasible in some cases, not others. (Of course, NY should be able to turn a healthy budget given the population density.. the mismanagement is evident)
I think it's a wise decision. Cash allows the poor easier access. Plus more options help money circulate easier.
