My son spent his first six years in San Francisco. Canadian dad, Japanese mom. He went to Japanese preschool and spent close to two years (kindergarten, most of grade one) in a Mandarin immersion public school. We moved to Japan after that.

His younger sister (three years his junior) began French immersion in Japan. Actually, a truly French school, started by French parents living in Japan. Since our son was working on three languages, and there were limited options for being immersed in Mandarin here, we decided on French for her.

Fast-forward eight years, six of which were spent in Japan, and two in the UK and France. Our son is bilingual, but his English is short of native. Japanese took over as the dominant language for him. His Mandarin is as good as gone, in spite of three extended trips to China and the (intermittent) use of native Mandarin tutors while living in Japan. I gave up on Mandarin for him when I realized how much his English was deteriorating.

Our daughter is native-level Japanese and English, and just short of native in French. She speaks without an accent but is short on a lot of vocabulary, for example. (Similar to my son and his English.)

Looking back at the experience of raising these children with multiple languages, my main observation is that, although children are superior at learning languages compared to their adult selves, there are starkly different levels of language acquisition ability from child to child.

My daughter is truly a language monster. She is shockingly impressive in all three of her languages, and is constantly trying out new words and getting them absolutely right (context, etc.).

My son is, not surprisingly, much like his parents. Language is hard for us. He is stronger in other areas (music, visual art, writing ability), and we work hard to let him know that everyone has their strengths and weaknesses. He's jealous of his younger sister's French (and her English, too), but we tell him that we're jealous, too!

My second observation is that raising children like this is a substantial amount of work.

Last but not least, I have come to appreciate the joy and magic of being truly, madly, deeply native in a language. Having that final 1% of ability adds untold richness and closeness. There's nothing quite like it. Being truly bilingual is fantastic, but not the same as being dual-native, and it doesn't come close, in my opinion.

And, as an afterthought, there are all the non-spoken aspects of another culture, such as behaviour, body language, and even the volume of your voice, that are, in my opinion, as important as language fluency in terms of feeling "close" within a society.
Suppose you don't know whether something is good or bad for your health. Other people are eating it, so it's probably not insta-deadly, but you suspect that eating too much of it might be bad in the long term. Meanwhile, some people are telling you that it's actually essential for good health (e.g. cholesterol), and some are even worshiping it as some kind of superfood (e.g. wine). Food science is a mess.

So you eat a little bit of it just in case it's essential for good health, but not too much of it in case it turns out to be bad in large quantities. Basically, you hedge your bets.

Wash and repeat for nearly every type of food that exists.
Its a transient equilibrium during growth, not a zero-sum game. We could see lower fees and miners earning more :

Hypothetically, if blocksize went up tomorrow by 8x, then potentially fees might drop by 4x and volume of transactions go up by 8x .. then miners will be making 2x in fees per block, for maybe 2% extra cost.

That has other flow on effects - if fees are lower bitcoin can accommodate people using it as a day to day currency, then its utility and user base goes up, then the valuation in USD goes up, the value of the bitcoins miners earn/save goes up, etc.

I think there are miners who understand that there is a sweet spot of fees being low enough to facilitate higher daily usage and growth. Also, the majority of their current income is not in fees, but rather in 'coinbase', the reward for mining the block [ which is how new bitcoin money supply is injected into the system ]. They are highly vested in the valuation of USD/BTC, so they will do well if the user base of bitcoin grows.

> A world of free economist articles would be _____ richer.
Yet they built the paywall.

The actual analogy would be a world where you need to get a visa per-magazine to read the articles they have, to the which you might not qualify.

A newspaper-immigration-patrol would look at this comment of yours on HN and possible deny you access, you should watch out.

> What are these institutions, and would they be damaged at all by free movement? If the people in good_country made the institutions, and they get demographically boxed out by people in other_countries, what happens? What are "institutions," exactly? Why did other_countries grow bad institutions? Would emigrants damage those countries further? The article semi asks these questions then drops the thread.

A great open question is what happens to institutions when there are culture changes. But bear in mind that without immigration, there would be no institutions in the U.S. whatsoever. It is a point of view of past immigration being great, but current and future immigration being bad, which I think it makes very little sense holistically speaking.

> Yeah they could, but most won't.

There really isnt a limit on living space. The rent is high in places like the bay area precisely because moving there is still a good deal. Problems of residential prices are widely overstated.
Hello from Germany.

We effectively have "free" movement of people from Africa to Europe. Once they're ashore, we can't readily send them back. We also used to have movement from Iraq and Syria through Turkey, but that was curbed.

We took in about a million refugees and we did not manage to integrate well over 90%+ into any form of employment. We don't have jobs for these people. It has cost us about 20 billion in 2016, about 3% of taxes earned total, to support these people. We've managed to "oppress" the flow of refugees with unpopular measures. If we didn't, how many more people are we supposed to take in?
> Scammers try to take advantage of both buyers and sellers online, but OpenBazaar uses a unique feature of Bitcoin that helps prevent fraud: Multisignature escrow. In this unique e-commerce marketplace buyers and sellers agree to a mutually trusted third party before they start a trade, and then the buyer sends his bitcoin to an escrow account. Those Bitcoin can only be released when two out of the three parties agree where it will be sent. Normally the buyer and seller are the two parties in agreement, but if there is a dispute the third party will come settle the dispute. These third parties offering dispute resolution are selected on an open marketplace.

It is one of the terrible side effects of all welfare programs. If you have socialized medicine, suddently it makes sense to ban products and practices for public health (since it lowers costs). If you agree to split the bill with the friends, you end up having to make rules on what people should be able to order to make sure things dont go too out of whack.
Would it be possible to re-magnetize an implanted magnet that has weakened over time? Or would that require exposing them to very strong magnetic fields, which would rip them out of the body? (I've seen videos of magnet manufacturing, and when they exposed the new magnets to strong fields to magnetize them, they were always firmly clamped in place so they would remain stationary).
Tech crowd is doing pretty well as it is. Low skilled and unskilled workers are already kind of f#$ed, with more to come due to globalization, and (later) automation.
Still thinking in the wrong way.

The health of a diet can only be considered as a whole, not bit individual contributors.

"Food A is good for me and Food B is bad for me" is not how health works.
it is literally impossible to do fractional reserve lending with Bitcoin. each coin has chain of custody back to the inception by mining reward (blockchain) so you can't send BTC you do not own. an altcoin could be built for fractional reserve lending where the coins are created by some form of consensus by a group of authorities. you could trade BTC and this theoretical altcoin but really we already have digital fiat currency for this purpose.
Ofc ethernet is used, but WiFi is often used for phones and additional devices like game consoles as it's mostly 1 port/person. The gathering and Dreamhack are two good examples of events with WiFi scaling to many thousands of connected devices without much problems. More or less every AP provider has solutions for this.
Residencies are one of the most grueling experiences for human beings ,and a restriction that makes doctors go through that process twice (in their home country and then in the US) amounts to a strong restriction.

Asking an experienced doctor to go through a residency is worse than asking software developers to get a doctorate if they want to write code in the US.
So what are the most optimistic projections of where blockchain and cryptocurrency could take us? How about the most pessimistic? Presumably, the likely outcome is somewhere in the middle. What would that look like, say, 20 years from now?
Learning a language is pointless as well as very very difficult if you have no opportunity to use it. I never got really far spending a coupple of years learning Chinese in the states, but got really far spending 6 months in china doing the same.

Learning French doesn't broaden your horizons. Using French does.
> it would also change the composition of the community from people who agree with our core ideals to a group of people who want to see a return on their investment.

Yes, it would. Good read, I like the overall reasoning. I can think of some use cases where an OB token could make sense but I would like to learn more about OB first.

If that were the case you would hope they would at least be good at software engineering, but all evidence points to that being completely false.
Healthcare is a serious business. Should chatbots help?
> Are there actual facts to back up claims to productivity boosts or failures with a given paradigm across large numbers of programmers and organizations?

NO. Functional people claim that, but never had a proof, since there aren't that many people using it to build large systems. Thus this myth lives on. :)
100% agree with the first part.

The second part is true, but the patients do not so clearly see the benefit, while the doctors would personally see and feel the pain of such a measure! The interest and understanding of the latter makes them very powerfully motivated.
Sigh. Except in battlefield and deep off grid situations mesh is always a bad idea.

I think that its quite possible that we can see scaling of 1000x on the linear blockchain, without fundamentally changing the economic/security properties.

Increasing blocksize is just the first thing to do of many engineering optimizations. If you want to climb Everest, you first need to reach base camp.

Even if LN works great and scales beautifully, we will still need that 100x increase in the blockchain that it settles on. LN itself will create transaction demand - people aren't paying $2.50 in fees now to buy a $3 coffee with bitcoin.
"Many" is still not thousands or even hundreds.
Also using rofi-pass, really it's better than browser integration. Especially if you bind it to a hotkey.
locomotives have two headlamps around 200W, and two ditch lamps (the ones at the bottom near the rails) of 350 watts each. That's 1.1KW already, plus any interior lighting and conversion losses from the diesel genset.

Also average freight train speed is tracked and its consistently less than 25mph:

https://www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/pu...

Note however that fuel efficiency is almost always given in mpg per freight ton, in which case the power usage of the lights would be amortized over the considerable mass of the train. >400 mpg per ton is not uncommon on a train.
I think there's even another layer that goes with writing code that gets thrown away. Sometimes I end up doing that, but through that I gain knowledge of the problem that I probably couldn't have effectively gained any other way. Should that time spent still be labeled "unproductive"?
You are not contributing to a discussion, you are asking for a service. Also I didn't imply you are trying to avoid taxes. You suggested that yourself.
Yes you need high magnetic fields to re-magnetize a magnet. Seems like you need between 1 - 2T magnetic field to saturate a rare-Earth magnet. So it's not something easily achievable in a homemade setup.
there is no reason you can't do that with OB. there is a REST API so you can make your own tools that send the digital good once payment is received.

It's one of the best quick critiques of libertarianism I've seen.

None of these ideas are new, they've been hashed out for years, and libertarianism has never really caught on because most people have an intuitive sense that mere property rights and enforcement of contracts are vastly insufficient to make a society anyone wants to live in--a sense that is reinforced whenever they think more deeply about what the arrangement of that world would mean for their lives.

(For example, take away tools for society-building such as public goods, e.g. roads, buses, libraries, health care, and replace it all with private equivalents, because now your main tool for running society is transactions. You're asking people to imagine a world in which they have to pay for everything, constantly, item by item. Like Joe Chip and his nickel-a-use door in that Phil Dick novel. People get what that would mean for their lives and they don't want that. Libertarianism gets more use as a joke in satire than in real world policy.)

It's not jut "motivation", you don't really learn language in a classroom...maybe you an get some tips and acquire some words, but you only really learn language in using it to communicate with people. If you have no people to,communicate with, it's like learning Java but not having a computer to execute programs on.

Sounds cool, I just read the explanation, it's on the Features tab. But in the gif it is showing that you will have to pay for it, and it will be a % of the total business. Similar to what already occurs in other markets. But, as it will depend on a person, not a company, what is the legal responsibility of that third person in the deal? Will these people have a profile or decision history so you can decide who to trust? And are they responsible for the quality of the product or just to ensure that people will receive their product?
Beg for forgiveness and give out free stuff, that generally makes people much happier :)
Would bash-on-windows thingy work for you? (Assuming it works with it)
Abstract – Generations of computer programmers are taught to prefetch network objects in computer science classes. In practice, prefetching can be harmful to the user’s wallet when she is on a limited or pay-per-byte cellular data plan. Many popular, professionally-written smartphone apps today prefetch large amounts of network data that the typical user may never use. We present Procrastinator, which automatically decides when to fetch each network object that an app requests. This decision is made based on whether the user is on Wi-Fi or cellular, how many bytes are remaining on the user’s data plan, and whether the object is needed
at the present time. Procrastinator does not require developer effort,
nor app source code, nor OS changes – it modifies the app binary to trap specific system calls and inject custom code. Our system can achieve as little as no savings to 4X savings in bytes transferred, depending on the user and the app. In theory, we can achieve 17X savings, but we need to overcome additional technical challenges.
Yes by your definition I don't think true bilingualism exists.

Right now I live in a situation where I use English and a third language exclusively, and my native language has massively atrophied. If I can't even compare my native ability now with 2 years ago, how could anyone have an exactly matched ability in two languages at the same time in all possible situations and contexts?

Hence I reject your definition since it's useless. I just define true bilingualism as native-level fluency in two languages. There's enough variation in native fluency to give a healthy margin there.
>It'd have to be running non-stop 24/7/365 for that to be true.

The federal standard for gallons per flush for urinals is 1 (with some older models using 5 times that). If we're assuming, they're accessible 365 days/year, that's 110 flushes/day. Seems a little generous, but it's nowhere near as far off as you're claiming.
I work in sales at Twilio and manage the account of a huge enterprise customer. We've sold to a few of their departments and what we've done so far has been successful.

But every time I call my contacts at this customer, something seems to derail us from the path to further integrations. They know our products work and save them money. But just last week I called Glenda in accounting only to find out her phone number now goes to some guy named Bob who refused to tell me what desk he works on or what happened to Glenda.

So I fired off a quick email to Vincent, the CIO, asking for an updated contact list since Glenda is gone and I heard Sally moved to outside sales. Vincent's secretary wrote back to me saying she'd "ping" him and "circle back". That was two weeks ago.

Last year when we closed a bunch of deals with this company I was recommending to my management that we spend even more effort to get further with them this year. But here I am halfway through the year and I feel lucky that my proposal was turned down because we were already too busy with other clients. What would another sales guy have done anyway, apart from dogfooding our sweet new IP phone stack as he wasted his time trying to navigate an endless megacorporate morass?
Sears Tower (Now known as Willis Tower) is a major microwave termination point in Chicago; great LOS from most of downtown.
Excellent point. I'm pretty sure this is a thing, I vaguely remember reading something about how getting promoted gives you some "invisible leverage" (my words) because now the company has decided you are valuable and special and they don't wanna look like they made a mistake.
Thanks, this actually helped me understand an instance of where several not very good managers got further promoted and it made no sense to me.
All of those require physical actions apart from just a digital transaction. At some point a human is trafficked somewhere from somewhere else, they can follow that. Chemical weapons are sent somewhere from somewhere, they can follow those. An assassin shows up somewhere, they can grab them there.

All of which can be orchestrated by the police themselves. In an anonymous transaction the other party could very well be the FBI.

That's too far the other way. Material that's safe in 10,000 years (which means the half-life is significantly less) is highly active and not something you want to hang out with unless it's shielded. The longer-lived stuff isn't all that great either when it gets inside you. Being near a bunch of uranium is fine, but breathing it in is considerably less fine.

Several countries tried your approach around the middle of the last century, pulverizing large amounts of radioactive material and dispersing it into the atmosphere. The results weren't catastrophic, but thousands did die from it.

We shouldn't be irrationally fearful of nuclear waste, but we shouldn't be completely blase about it either. The stuff is dangerous... just not dangerous on a level beyond anything else out there, the way many treat it.
Adult bilinguals mix their languages all the time; it’s a sign of language ability

I'm trilangual and that statement is complete BS. I would trade the decent mastery of three languages for complete mastery of one any day of the week. No one cares that I'm fluent in French or Polish expect for when I pronounce French words properly or can order two beers at a bar on a biz trip. People do notice that I tend to reel for pretty basic words in English. I guess it's always a matter of perspective.
