For anyone taking Melatonin as a sleeping aid: The dosages it is being sold at are way too high. Recent studies point to 0.3 mg being the right amount for adults [1].

That dosage (taken over a period of several months every day at the same time) helped me get through a period of insomnia last summer, when basically all the other medications failed or had too strong side effects.

The question of "clustering" is an old one in economics, and also politics and public discourse. PG addressed it a few times, for example. He also write about how to create new centers, fwiw.

It's not a straightforward question, and I don't think any answer is entirely satisfying. A couple of cents though.

1¢ - Industries like tech are a cultural phenomenon, like a music industry or art industry. You can't just decide that Warsaw will have Seattle's grunge rock scene. It just grew there as a cultural outgrowth. It can't be planted elsewhere with predictable results. The thoughts and little decisions made by people are influenced by their cultural context.

2¢ - For the best (in business terms) tech companies, currently, costs like salaries mean nothing.

Twitter and FB were Twitter and FB with 1% of their current visits and employees. The extremely profitable and businesses enabled them to hire tens of thousands of people and spend tens of billions per year. We're these people necessary to the ad part if the business that employs most of them?

I suspect that they aren't. IE, if it turned out FB could only make $40bn or $8bn pa (currently making $80bn) from their site, they would manage to produce the same fb with few compromises on a much reduced budget. This isn't BMW, where operating costs and economic output (the number of cars) are tightly related to eachother.

If google or FB want to increase profit margins, they can, easily, by a lot. They would if they needed to, but they don't. Capital markets like the idea that they are reinvesting for growth and capital markets don't have any better ideas for where to invest profits anyway.

With no incentive to cut costs, why move somewhere cheaper?

The "immobile incontinent patient scenario" isn't too commonplace. In my family and most of the extended families of my friends, you stay with your parents for companionship and helping them out in day-to-day tasks if required. You don't wipe their shit for 15 years, they're still pretty able-bodied and independent.

What is confusing to me is your insistence to see the worst-case scenario and treat what is the last 3 months of their lives to the year-to-year scenario.

Please don't call me simple minded when I'm trying to be civil.

Now, back to your reply. You're saying that for you to put your child in professional care you would have to be an addict or abusive or schizophrenic. However, these don't seem to be preconditions for putting your parents in professional care. So going back to the statement I was focusing on:

As long as you can provide good quality care, there isn't much of a moral difference how it's done.[1]

Is it fair to say that you feel this is true for one's parents but not for one's children?

Show HN: Norse Idle – A JavaScript Game for Mobile and Desktop
Hello HN!

I'm Danny. I'm building a browser game called Norse Idle (https://norseidle.com/).

Norse Idle is an incremental (idle) game where you build a northern village. It's set in the age of the Vikings. You can gather different resources, build normal and important buildings, hire villagers to automate the production of resources and learn new lore. Discover mysterious runes and raid bandits or villages.

Currently it is in the alpha, so there's content missing and the game has bugs and balancing problems. But some people are already playing it and like it so far. I've also created a growing subreddit for the game (https://www.reddit.com/r/NorseIdle/). You can post bugs there and suggest new features.

It has a very simple UI and is developed with ReactJS and MobX. The game is actually just created to learn programming with React. But it became more.

Version 0.0.4 went live yesterday. It includes new lore, raid improvements, new descriptions and some bug fixes. Many new features are planned for the coming weeks.

Stay tuned! Midgard awaits you! ᛉ
Single stream recycling is a really poor idea.

A better set of ideas that might actually help:

Reduce - as suggested elsewhere, eliminate parts of the packaging that aren't strictly required (outer seals, etc).

Reuse

* Create a set of standardized, rugged, containers that seal around foods.
* Actually use them to pack foods in standard containers.
* Which are then returned for cleaning and reuse.

Recycle

* Many bins, one for each type of allowed recyclable plastic.
* Also a compost bin
* Which would be different from a yard waste bin
* Make sure the reusable containers are also easy to recycle.
* Also, make an easy to read (human and machine) /large/ 'number' label.

Ban difficult to recycle things such as plastic fused to paper.

Depends on what you mean by "own". I would use "able to decide how it is used". So I would say that Mark Zuckerberg "owns" Facebook because he has a controlling interest (although he does not own 100% of the stock). I would say that Donald Trump does not "own" the US Treasury because our form of government contains checks and balances.

हृदय शरीर का एक महत्त्वपूर्ण अंग है। मानवों मेंयह छाती के मध्य में, थोड़ी सी बाईं ओर स्थित होता है और एक दिन में लगभग एक लाख बार एवं एक मिनट में 60-90 बार धड़कता है। यह हर धड़कन के साथ शरीर में रक्त को धकेलता करता है।हृदय को पोषण एवं ऑक्सीजन, रक्त के द्वारा मिलता है जो कोरोनरी धमनियों द्वारा प्रदान किया जाता है। यह अंग दो भागों में विभाजित होता है, दायां एवं बायां। हृदय के दाहिने एवं बाएं, प्रत्येक ओर दो चैम्बर (एट्रिअम एवं वेंट्रिकल नाम के) होते हैं। कुल मिलाकर हृदय में चार चैम्बर होते हैं। दाहिना भाग शरीर से दूषित रक्त प्राप्त करता है एवं उसे फेफडों में पम्प करता है और रक्त फेफडों में शोधित होकर ह्रदय के बाएं भाग में वापस लौटता है जहां से वह शरीर में वापस पम्प कर दिया जाता है। चार वॉल्व, दो बाईं ओर (मिट्रल एवं एओर्टिक) एवं दो हृदय की दाईं ओर (पल्मोनरी एवं ट्राइक्यूस्पिड) रक्त के बहाव को निर्देशित करने के लिए एक-दिशा के द्वार की तरह कार्य करते हैं।

हृदय की मांसपेशिया जीवंत होती है और उन्हें जिन्दा रहने के लिए आहार और ऑक्सीजन चाहिए। जब एक या ज्यादा आर्टरी अवरूद्ध हो जाती है तो हृदय की कुछ मांसपेशियों को आहार और ऑक्सीजन नही मिल पाती। इस अवस्था को हार्ट अटैक यानी दिल का दौरा कहते हैं। ( इस सिलसिले में कुछ लोगो को भ्रम हो सकता है कि दिल से संबंधित और भी समस्याएं होती हैं जैसे – हार्ट वॉल्व की समस्या, कंजीनाइटल हार्ट प्रॉब्लम आदि, और जब हम दिल की बीमारियों की बात करते हैं तो आमतौर पर इन्हें शामिल नही किया जाता परन्तु यह समस्याएँ भी हृदय रोग से सम्बंधित होती है)

> Cynical observation. Not every human action is automatically designed to impress upon others.

That is not what the word signalling means.

Signalling is a means of communication. Singalling is much more efficient in many contexts than other communications methods like straight up talking and describing one's life.

Communication has many reasons for it, only one of which (quite minor for many people) is "impressing upon others". Saying signalling is done for "impressing upon others" is a gross simplification of this phenomenon and is just inaccurate.

Since they're geopolitically separate and have their own infrastructures, the distinction is quite apt for understanding the "who" of who is impacted when the specific cables are cut.

In other words, based on your assumption that "Ireland" is precise enough and since Belfast (NI) has it's own IX, that would mean that you would have dichotomy where "Ireland" could connect to the internet and "Ireland" could not, yeah?

The problem with the AUR is its semi-official status takes the pressure off the 'community' binary repositories, while not being up to the same standards - many packages are out of date or don't build, and the complete lack of gatekeeping renders the user vulnerable to malicious packages. Note that "AUR helpers" are not officially condoned by Arch Linux, despite the system being unusable without them - officially you're supposed to examine all the PKGBUILDs of all dependencies manually to make sure they're safe.

I prefer the Void Linux approach - every "template" (equivalent to Arch's PKGBUILD) is kept in a single, monolithic git repository, and the barrier to contribution is kept low; just submit a pull request, and a core developer will review and accept it. This way all packages have binary builds and all packages have had at least nominal review, yet the repository is surprisingly broad. And if you need something that isn't in the repository, adapting an AUR PKGBUILD is trivial.

> * Create a set of standardized, rugged, containers that seal around foods.

We used to actually have this: it was wooden/plastic crates and boxes, pallets, burlap bags, and glass milk/juice/beer bottles.

We're moving backwards, and it's all due to economics. Reuse of those materials back then was motivated by the cost and difficulty of producing those containers. It simply was not economically feasible to produce a single-use crate or glass bottle--too expensive. Economics and the wonder-engine of capitalistic progress has now given us the ability to manufacture trillions of single-use containers for literally less than a penny a piece. It's just far cheaper and less of a headache to just produce, wrap, and then toss the waste. No one wants to deal with all the niggling details of carting bottles back and forth, washing, them, filling them. Just too much of a pain in the ass. So we get what we have now. Clean, no fuss, no mess. Just toss it.

In many ways, our older economies--full of poor working saps who had to lug bottles back and forth--was far more sustainable than today's system. But today we're rich and lazy and awash in our own trash. Progress!

Probably bad that the Trump administration don't want to invest anything in AI Research, but to claim it's a brain drain just because the US don't have open borders is a bit ridiculous for me as an European.

There is still immigration to the US and by the looks of it mostly educated immigration. I could imagine myself moving to the states in the future and I don't think it would be impossible for me to do that?

The US still have very large and popular corporations that invest heavily in AI research. Just because it isn't government funded it doesn't mean that the US won't be competitive in that field.

I'm sure the country where I am from, Sweden invests more than $0 into AI research but I am also sure that we probably won't be able to compete with the US.

Thank you for the extensive response. With that context, I would say "full control" should amount to the ability of a pilot to overrule systems that may send an aircraft nosediving due to faulty sensors.

Did the pilots of the Lion Air flight and possibly the Ethiopian Air flight understand what was wrong in-flight and were unable to fix it due to an inability to override aircraft controls?

This is what I am getting out of the discussion so far but maybe I am gravely misunderstanding what's happening? So as a passenger without any knowledge of aviation systems my question is merely whether the pilot gets control over the aircraft when he demands it? Fly-by-wire should at least never lead to autopilot suicide, even if it has to ensure flight integrity to a certain degree due to the technical nature of large, modern aircraft.

Interesting to read, and see this exists.
It seems fairly obvious and in line with most research that has come out that #1) vaping is far less dangerous than smoking cigarettes, #2) vaping is not harmless and the true extent of the risks probably won't be known for a generation because there are just no longitudinal studies possible yet, #3) vaping is a great alternative to smoking cigarettes in terms of harm reduction - both in terms of effects on the vaper and effects on bystanders (not to mention it doesn't cause entire rooms and all things in them to stink) #4) The extent that vaping will lead to more nicotine addicts later becoming cigarette smokers is unknown, but seems anecdotally unlikely but worth keeping an eye on (ie; someone that never would have started smoking starts vaping because it is less harmful but then eventually becomes a cigarette addict) #5) Prohibition doesn't in general work with any substance and there is absolutely no moral justification for not making safer ways of delivering substances available while still being open-eyed about their possible risks

Personal bias - smoked heavily starting at age 13/14 until my 30s. Switched to vaping heavily and saw marked improvements in my health. Eventually weaned down nicotine levels while vaping over the course of many months. Quit vaping with some difficulty, but not the difficulty level of quitting cigarettes. Now don't use nicotine at all, but will never be able to use it in moderation.
Recent graduate in Optical Communications here :)

1) The fiber is pretty thin, but there are several fibers combined in one transoceanic cable, see here https://en.wikipedia.org/wiki/Submarine_communications_cable. They don't patch them, but splice the fibers. Patching introduces a little loss, so it should be avoided.

2) Not sure how deep they are buried, but I think to remember that the shore end of a submarine cable is better protected than the part in the deep ocean. Due to more ship traffic at the coast etc.

3) Good question. The loss of an optical fiber is roughly 0.2 dB/km. Across the ocean the optical signal must be amplified several times (every 80-100km). Nowadays the amplification is all optical (EDFA or Raman). Before there were electrical regeneration schemes. Check out the history of the field, it's is quite interesting [1].

4) Not sure how much data such a cable can carry, since it depends on how many fibers are deployed within. However, there are multiple interesting things to look into here. In research labs, people are investigating multicore/multimode fibers (space division multiplexing) [2], these fiber have incredible capacity. Personally, I think the most interesting metric is the spectral efficiency, so how much data can be transmitted per second per Herz. Such a metric is independent of multiplexing schemes over space/wavelength/time, and improvements have to come from better devices, signal processing or signal shaping methods [3]. Another mind-blowing area is using the nonlinear Fourier transform for better signaling methods [4].

Feel free to ask more questions :)
