I looked at Elm a couple years back and decided on Purescript instead: http://www.purescript.org/

Has a much better FFI story with JavaScript than Elm, and has a more powerful type system (higher kinder types, etc). Row polymorphism makes writing pure code a joy, the effects system is unobtrusive. I actually enjoy programming purescript more than Haskell.
Another reason is that China wants its domestic recycling (meaning curbside collection) industry to develop. While the processing industry can get cheaper input through importing, it lessens the interest in collecting domestic sources, generating more pollution or waste for the landfills.
I grew up with stories of people like Maco Polo and love of travel but my recent trips to Europe has almost repulsed and disillusioned me. Tiny European countries are being swamped by huge swath of tourists, everyone with Rick Steve’s guidebook, they all go look at exact same thing, take exact same pictures and even eat at exact same recommended restaurants. There is a lot to see and little to reflect when you are among herds of camera clicking tourists. I wonder if there are any other guidebooks people use (especially for Europe) that puts them more on path of becoming traveller and less on tourist.

Probably this is one reason why gig economy is much bigger in the US than elsewhere (excluding cross-border services delivered from poor to rich countries). Airbnb is big in other places, but Uber much less so.
I would have liked to have seen custom operators stay around in 19, but I understand the motivations. I think it was in 18 they removed back-ticks for the same reason. Just makes it way easier for newcomers to learn the language.

As far as I understand it, the native modules lockdown had to take place. Period. The one thing that most attracts myself (and many others, I'm sure) to Elm is the guarantees that the compiler gives you towards ensuring no run-time errors. Give folks the ability to author and publish Elm native modules and the entire platform loses that guarantee.
Artists rendition.

When I look at the bust of Nefertiti I like to imagine Nefertiti saying something like "destroy it, make the nose a little smaller, then execute the artist".
Author here. So amazed to find that my blog post got featured on Hacker news. Happy to answer any questions that I can! :)

The article doesn't mention self-driving anywhere.

Am I misunderstanding you or did you not read the article?
In context, he means that leadership is difficult because you have to bring people along, whereas automation doesn't require you to establish alignment with anyone else. I'm skeptical that it ever works that way, but it's not quite as woo as it sounds art first.
How about looking at the facts that she presented. Her articles might be negative because that is what the facts indicate.

I trust her article because she focused on the facts:

* delivery address information wrong

* heavy boxes

* No ability to contact recipient for delivery

* unreliable app for scanning packages

* etc.

"Balance" is bs if balance comes at the cost of accuracy.
> 1. The younger generation (myself) does not like commercials, and are willing to pay a subscription fee to remove them (ie Pandora one, Hulu+, Spotify Premium.) Either the commercials pay for the content, or or the consumer pays, not both!

We say this, but then we endure the ads on Amazon Prime Video. But how do we cancel Amazon Prime Video without canceling the rest of our Amazon Prime subscription? Prime is like the cable bundles - how long until we cut our tether?
Are you using tor by any chance? I use cookie autodelete (equivalent to creating a new container every time I close all google tabs) and I only occasionally get captcha challenges. This is on VPN, so when that happens I just switch to another region and it works fine.
You're correct that other languages have first-class functions which are capable of handling context without the implicit-this style like JS. Rust, for instance, uses `self`-as-first-parameter style.

However, `this` has nothing to do with functions being objects, besides the fact that the prototype object is a member to the constructor function.
My rule of thumb is this: Does the solution solve more problems than it creates?

Taking the example of Vue.js, I found that it makes building UIs a lot easier. But I found that you do need to understand its caveats and its limitations (e.g. limitations in its reactivity system). On balance, it does solve more problems and those limitations are really minor and well documented.

But before I embraced it, I spent some time experimenting with it, assessing the documentation, the community, ecosystem, etc...

I think this is a skill onto itself that comes with experience. I remember jumping on the "cool" bandwagon many times, only to realise I was basically wasting a lot of time switching to cool new technology X.

Nowadays, if I can't understand the problem something is trying to solve, it probably means I don't have that problem.

Edit: added "limitations in" its reactivity system.
Is there any way you could go into more detail on this or refer to some sources? In all honesty, your comment sounds vague and a bit esoteric, still interesting enough that I want to know if there some hidden truth to it. It can’t be that difficult
I recently saw a 6-year old boy delivering a package for Amazon. He got out of a regular van, dropped off the package, and bounded back to the car. I guess he was probably the child of one of these Flex contractors.

This happened just off Sand Hill Rd., as it happens.
If you value compile times (and you actually think generics make a difference, I do not) you would not make slices and hash tables generic like in Go, would you?

If you wanted a simpler language, you would not make slices and hash tables generic, would you?

If you wanted lower learning curve, you would not make special case generics would you?

If you wanted to wait, to get the perfect generic solution because a sub-optimal one is not good enough, you would not create a sub-optimal non-perfect temporal solution with special-cased generics for certain data types would you?

If you argue that I am loyal and not honest, and therefore like generics because it is used in my favorite language, I think you are wrong.

The languages I use most of the time have a huge design flaw. It is called null. But when they created Go they chose to (except in special cases) get rid of (useful) generics instead of the disaster that is null.

The problem is that Go has not learnt from other languages. It is too imperative, not expressive enough, lacking in static typing and horrible at fault handling.

JavaScript Fundamentals: it’s “JavaScript”, not “Javascript” :P
Always worth posting Wallace's quote on the subject:

"To be a mass tourist, for me, is to become a pure late-date American: alien, ignorant, greedy for something you cannot ever have, disappointed in a way you can never admit. It is to spoil, by way of sheer ontology, the very unspoiledness you are there to experience. It is to impose yourself on places that in all noneconomic ways would be better, realer, without you. It is, in lines and gridlock and transaction after transaction, to confront a dimension of yourself that is as inescapable as it is painful: As a tourist, you become economically significant but existentially loathsome, an insect on a dead thing."

A similar phenomenon is happening in the outdoor industry. Instagram is (depending on your perspective) ruining everything or democratizing access to natural beauty. Most people I know practice some variant of a digital leave-no-trace rule: don't post photos in publicly-trafficked areas of the internet, or if you do then don't say where they were taken. It's not so much gatekeeping as ensuring people who want to experience that beauty have to put in the work - read terribly-designed websites, meet actual people and gain their trust, or even take a backcountry travel class which hopefully instills a healthy respect for the environment you're enjoying.

Another strategy is to delve further into mountaineering, where the obvious danger of the terrain repels everybody with a working survival instinct and ensures some degree of solitude :)
There is some empirical research that our attention spans are degrading on average. I don't have any of it handy, but there's a great book I had to read back in high school called "The Shallows" by Nicholas Carr that goes into it.
How can a jury decide on a cancer cause when scientists can't agree?
Advertising is zero sum for advertisers, if you make it harder for everyone to advertise, no one loses.
I often wait until I have a personal connection to a place, such as a friend or related hobby, before traveling. The experience becomes very removed from that of a tourist, and so much more rewarding.

Am I selfish if I put extra effort into maintaining friendships with foreign friends so I might end up visiting them?
Oddly, I have pushed back on many devs introducing generic interfaces. For library writers, they can be nice. For everyone else, they typically just get you in trouble.

So, I don't want to remove them from the language. However, I do question a large percentage is their use in everyday programming.
Since seeing means perceiving things in space, for starters it requires having a notion of 'thing' and of 'space'. Do computers have such notions? Again, based on the evidence that we have, or lack thereof, regarding the cognitive capabilities of inanimate objects, I say the answer is a resounding no. Inanimate objects do not think and therefore cannot have concepts. They cannot do anything, strictly speaking, since they lack agency. We use them to perform certain things, which is different.
Popper is immensely influential in science, well worth a closer study. Agree there are some similarities with Socrates but as far as I know there was no drive to have Popper drink poison (a tribute to the imprint of that ancient Athenian on modern society maybe). Except perhaps in communist countries, the expressed antithesis of Popper's "open society".
> Laborers were paid next to nothing by current standards, and lived in poverty below current day third world levels.

That's true. But...

> labor was next to worthless.

That does not follow. Before the industrial revolution, nearly everyone, even royalty, lived in what would today be considered poverty. Labor as a percentage of total economic output was much higher before the IR than after. It's just that overall productivity vastly increased.

> Many industrial jobs were created and wages rose as competition for workers intensified.

That's true, but...

> The industrial revolution made labor more scarce.

No, that's not true. Yes, many jobs were created, but many previously existing jobs were destroyed. Unemployment as it exists today was unknown before the IR.

Please note that I am not saying that these changes are bad. Before the IR, an unemployed person would have been a dead person because there wasn't enough economic margin to support an unproductive population. Unemployment was a luxury that pre-IR society simply could not afford. Society as a whole is vastly better off because of technology. All I'm saying is that the rules we have for how wealth is distributed is based on assumptions that are becoming less and less true as time goes by, and that we need to address this or it will cause more and more serious problems.
It complicates transportation to sell all goods in bulk. I'm glad that stores don't charge an extra 1.5 cents for the plastic bag around every gallon of milk and pound of rice.

You, yourself, might have enough responsibility and self-control to prioritize cleaning your containers, but this is not true for all humans. The store would lose business if their competitor sold milk already in bags or boxes, but you had to bring your own milk bag to their store. And someone's bags might have bacterial or other contaminants and get them sick, then they blame the store and get the health department to shut them down. (Tangent: Why is most milk still sold in boxes, and not in plastic?)

Glass is fragile, metals cause unexpected chemical reactions, wood is permeable & requires additional materials (wax, glue) to seal properly, and cardboard has poor durability.
Ask HN: Can anyone explain how DWave was able to scale to 1,800 qubits?
I have a bunch of questions about the recent Nature article and about the underlying simulation itself.

1) how are the individual qubits arranged/"built"

2) what is specifically meant by the topological phenomenon observed, and how does this relate to the quantum simulator accurately predicting what the classical model said what occur?

3) what is the interplay between "performing a computation" and running a quantum simulator? not really seeing the immediate connection there

4) last, not sure how far DWave had come previously to achieving such a large-scale computation with this approach, but it does seem like a pretty huge number of interacting qubits compared to other highly-entangled systems

Thanks

Sigh, looks like you're right. The person who reported the updated version to me in fact saw their homebrewed Python 2.7 as 2.7.15. So I buried a good chance to raise visibility to the issue when it was still on the front page.
In my mind, this could be solved fairly simply with government regulation. The government can sell tourism passes to enter the country, therefore socializing some of the profits of tourism, or even just hand them out in a lottery. It seems obvious that this will need to be done at some point; there are fundamental limits on how many people a country's infrastructure can support. Without the government stepping in, it will only get worse.

Or we could build more walls.
Netflix originals are a form of bundling too. There are many in completely different genres now, with very different budgets. It's unlikely a particular netflix viewer will want to watch most of them, nevermind the back catalog.

And yet, a netflix subscription is 1/4 the price of a typical cable package, with no ads, on-demand for everything, and a better discoverability process. If that were the experience of cable, people wouldn't mind the "less popular" things.
It would usually be the same airline that did the long flight or one of their partners - but Ryanair and Easyjet don't do those partnerships with Chinese airlines. I've also gotten a lot of their flights and hardly ever see Chinese tourists, mostly local (or other European) tourists in fact.

As a side note: I have the feeling spiegel.de is getting worse and worse by the day. Ever increasing click-bait titles, aricles with little depth, more and more content paywalled. And don’t get me started on the page filling ads... or is it just me?

Ouch
Walking across the United States is a slightly-uncommon and somewhat historic hobby. It can be done in under 300 days.
Money can’t solve all your problem, but it will solve most of them.
This is one of my favourite ways to travel (when feasible), but if there's somewhere you want to go, just go.

I was lucky to work in a city full of expats - so I now have friends all over the world to lean on.

In return, they lean on me when they want to visit my home country and I happily oblige.
Restructuring Alternatives for Troubled Private Equity Portfolio Companies
People cared about “Net Neutrality” because the name has a “free speech” ring to it, even though that isn’t really anything to do with that. How could anyone against the internet being neutral?

I think “decentralised” isn’t going to drum up any interest unless you can couch it in the terms of a movement that people already understand and can be certain that it’s something the “good guys” would definitely want.
Exactly, take a look at https://github.com/utkarshkukreti/purescript-hedwig/blob/mas...

I think anyone who is already comfortable with elm can look at that and be productive in purescript very quickly.

* Of course, with purescript there is going to be a bit less hand-holding. But the side-projects I see folks posting about in done with elm are done by folks that already do things on their own.
No idea if they do that, but good point if so.
Right? I thought that was the new normal.
It's a fine line to draw... On the one hand, I feel like I have some form of "new information addiction". Even my dad, who is 70, has pretty aggressive surfing habits.

On the other hand, I skimmed books back in the 90's, before I surfed the web daily. (There was much less "new" high quality information online then.)

I would check out 5 books at a time from the library, and read the best one, and skim the rest.

I also studied for my AP History test in exactly one day by skimming, and got a great score. IIRC, I read the first and last sentence of every chapter in a 200 page book in one night. It's not a bad way to read if you're looking for the high level structure of stories and arguments.

Many authors are in love with their own prose, and it is too long.

My blog looks dense but I've gotten good feedback on it, mostly because I use skimmable headings, and delete words from sentences, so it's short and dense:

"Money is coined liberty" -- Fyodor Dostoevsky
USSR did the same thing. Pretty sure it was done to promote competition and not for divide and conquer. Secret police was more than enough to handle dissidents. Hitler and his party actually had a lot of support because most of the bad stuff they did was hidden from the people or justified super hard through propaganda. And as bad as the Nazis were overall they still managed to have major successes in economy and science.
I only briefly dabbled in Elm and I'm not terribly qualified to comment on specifics, but I had a similar, negative impression of the way the project is managed. Especially in comparison to many other open source projects.
This is actually done with certain destinations in the US. For example, after "The Wave" in Southern Utah became tremendously famous (driven, IIRC, by a very nice desktop photo distributed with Windows), access became permit-only determined by BLM lottery.

I've been trying the lottery w/o success most months of the last year. It's frustrating not to win, but it's a fair way of meeting the demands of both access and preservation.
I don't buy that this has anything to do with the rise of the 'digital world'. The unfortunate reality is that adult literacy statistics are scary. A huge number of adults just aren't capable of understanding more than the most basic writing. See NAAL (https://nces.ed.gov/naal/) and PIAAC (https://nces.ed.gov/surveys/piaac/) data.
I like halogen, but elm folks may want something more familiar (and with less type variables).
Well that's why airlines like Ryanair exist. If say Lufthansa is booked up by Chinese tourists and prices are rocketing, that leaves a gap in the market that these airlines fill.

Also people aren't stupid. They shop around and find good deals. I've seen many South Americans using London or Amsterdam as hub airports before jumping on cheap flights to Spain/Portugal etc.
Awesome. How cool is that?
It's possible, but there's a lack of tooling, tutorial, and the performance of your apps will suffer. Slow startup and high memory usage.
This Wallace guy is certainly proud of his opinions, I'll say that for him. The important thing is that he's found a way to feel superior to pretty much everybody.

I especially like how he can write something as prescriptive as, "To be a mass tourist, for me, is to become a pure late-date American, alien, ignorant, greedy..." while literally admitting that he can speak only for himself ("for me."). The greatest magicians are the ones who come right out and tell you that they're going to try to snow you, and then proceed to do so.
I believe there is a very high fee attached to checking in 23kg-32kg bags (€80?) which are then specifically marked. It wouldn’t surprise me if it’s added for free on some business class fares.
"alien, ignorant, greedy for something you cannot ever have"

I find this hugely classist. (Edit: and I'm generally not someone to use that terminology)

Most (even American) travellers are just trying to see some sights, have a normal and are not particularly rude or problematic.

The issue is now that 'everyone' can afford to travel ... it's causing problems.

This is a problem of prosperity.
I think of it the same way. Money is power, and the most important kind of power for your own well-being is control over your own life. Whenever I get very stressed at work, I find it reassuring to think that, worst case scenario, I have enough "fuck you money" piled up that I could walk away and take my time to look for a new job on my own terms. Knowing this in the back of my mind also allows me to negotiate my working conditions more boldly. I dare to pick projects I'm interested in and say no to others.

I have a fairly high-paying job, but I would like to find a way to earn more eventually. Not so I can be filthy rich and buy myself ridiculous things most people can't afford, but so I can have the freedom to take a sabbatical and travel, or start my own business, or heck, retire early, while I'm still healthy enough to enjoy life.

I grew up poor, and to me, having more earnings/savings makes me feel more safe and in control of my life. The biggest difference it has made recently is going from having roommates to having my own place. I'm an introvert, I need time alone, and I find it really rewarding to be able to come home to my own little sanctuary after work.
These kind of stories make me value Go's approach a lot more. You just have to worry about making your product better.
No. Falsification is necessary but not sufficient. The best theory is one that has two properties: 1) it is consistent with all the observed data (i.e. has not been falsified) and 2) it is a "good explanation". Explaining what is meant by "good explanation" is too long for an HN comment, but roughly speaking it means that it is concise and brittle -- any modification would cause it to become inconsistent with the data.

(So for example, conspiracy theories fail as explanatory theories not because they are inconsistent with the data -- they generally aren't -- but rather because they are not concise and brittle.)
