Why "of course"? No design is needed since this sort of thing could easily happen by evolution.

Marketing is empirical and competitive. Some companies could have discovered that recyclable products sell more without necessarily understanding consumer behavior all that well, and the rest can copy them. They aren't likely to question it if it works.

Which isn't to say it can't be by design, but that's a matter of knowing the history behind it.
As a software developer (not a pilot), I think this misses the mark. Airbus has succeed in commercial fly-by-wire because their system provides protection over the full flight envelope of the airplane (the specs it can withstand without crashing) and also lets the pilots back off on that automation when they need to.

The Boeing MCAS solution isn't full flight envelope protection. As a family member of an Ethiopian crash victim put it, "Why does the software intervene to push the nose down if it thinks it's stalling but not to push the nose up if it's going to hit the ground?"

This is a case of failure to properly certify mission-critical software and it reminds me of Toyota's unintended acceleration problems with the Prius, where the company was found in court to have willfully ignored standard protocols in testing mission-critical apps.

I believe it gets much hotter in the upper atmosphere. Though there isn't much actual matter there.
I had this impression as well, but there's something else going on. If you run the numbers, at T=293, there's a negligible fraction above 5 km/s. The atmospheric loss models typically use an exosphere temperature of T=1000, but again, negligible fraction above 10 km/s.

However, there were some contradictions I couldn't immediately understand. This source [1] says "Only about one in a million helium atoms is lost from Earth via Jeans’ escape.". But it also cites a plot from [2] showing the rule-of-thumb for Jeans' escape: 1/6th the escape velocity vs the RMS thermal velocity. In this case, He has an RMS velocity of 2.5 km/s at T=1000, which is greater than 1.9 km/s.

It is also that younger folks are using tech today and they are not bothered by having to try things. For some reason, I've seen older folks scared of trying things and want instructions .. perhaps because they've seen tech fail so badly in their lives. Younger ones try things until something clicks and then they learn that and move on.

The underlying design principle is close to "undoable" .. but not quite that either and perhaps "design for experimentability" captures it better. It may also just be the more common insignificance of actions to be taken - "publish a document" versus "like a post" or "take a selfie".

Edit: I am amused that math instruction is "irrelevant" and puts unfair stress on students, but spending many hours perfecting throwing a ball through an iron ring is somehow worthwhile because one has a microscopic chance at a short career playing pro ball. Even more amazing is that colleges consider rowing a boat as a leg up for qualification for admission. (There are even fewer careers available for boat-rowing than ball-throwing, if that is even possible.)

The open WWW is one of the greatest things that humans have achieved, and Google is in the process of destroying it. It looks like the goal is to replace the Web with their own product where ads and tracking can't be blocked, and fewer people leave Google's servers.

This new replacement for the Web will only fully work in Google Chrome, because Google is abandoning true web standards with things like AMP and Portals. (Being forced to include Google's JavaScript in your web pages under threat of losing your traffic is not a real web standard.)

The bulk of what is published online will have Google's visual branding (Material Design), and you might never leave Google's servers (as a user) or be able to fully control your own tech stack (as a publisher).

AMP is a vicious attack on the open Web and a completely unethical power grab. This is why one company shouldn't control the browser, the search engine, and the operating system at the same time.
And in firefox I can enable or disable pre-fetching/preloading not sure about chrome.

However, if the user has disabled pre-fetching what makes it okay for AMP to do it?

And why on earth would those EB-5 visa holders have invested in low-income housing? Nothing in the visa requirements description seems to mention 'low-income', 'distressed', 'economically disadvantaged' or anything of the sort. [0] Here:

> All EB-5 investors must invest in a new commercial enterprise, which is a commercial enterprise:

> Established after Nov. 29, 1990, or

> Established on or before Nov. 29, 1990, that is:

> 1. Purchased and the existing business is restructured or reorganized in such a way that a new commercial enterprise results, or

> 2. Expanded through the investment so that at least a 40-percent increase in the net worth or number of employees occurs

The closest thing is how it specifies amounts - $1m in general, or $500,000 in rural or high unemployment areas. Which is closer, but still doesn't require low-income housing...

What Causes Color Blindness?
I think the biggest opponent of climate change is simply apathy. It is not that those people don't believe in it, they just don't care. It isn't as tangible or life quality effecting in the immediate term as air pollution was. It is more like the water will rise a bit, so what? Getting Americans to take climate change seriously will require a huge undertaking.
It's not about the best way to behave differently at runtime and sometimes call exit depending on how the script was invoked, it's about the idea that a scripting language would SUPPORT and ENCOURAGE writing that kind of script, with a special magic built-in variable and a section in the already-complex documentation encouraging its use.

Scripts should not behave differently depending on if they were invoked from other scripts, and modular reusable libraries should never take it upon themselves to call "exit" when there's an error.

The way to control the flow of recursive functions is by passing explicit parameters (like the recursion depth, or a data structure to walk, or an error callback), not reflecting on the depth of the runtime stack or looking at how the function was called.

If bash is too weak to handle errors, or exceptions, or recursion, or passing functional callback parameters properly, or even file names with spaces in them, then use a better scripting language, don't just throw up your hands and exit.

The article talked about it happening partially by machine and partially by hand. At least, in whatever system they looked at. I'd guess this varies.

Either way, the blue bin encourages "aspirational recycling" where people just put in anything they think might be recyclable, rather than following the rules based on what their local recycling system can actually handle.
The scaling laws probably have something to say as well: twice the size means 8 times the mass, so adults are, on average, more delicate than children. There might be a similar undiscovered principle for cognitive function, but that's speculation on my part.

On the whole, though, I completely agree: there's a lot of ageism and resignation among adults about what is and is not within the abilities of the determined adult. Everything include language acquisition, learning to play musical instruments, mathematical creativity, and making scientific discoveries.

As a person transitioning into "unambiguous adulthood", but with plenty of youth left (I am only 30, for reference, and as creative as I ever was), this is super frustrating.
In developing countries, the bottled water is also about sanitation. When I go to India, I am very careful to never let tap water or anything that might be tap water near my mouth. That means lots and lots of bottled water, sealed until it gets to my hands.

You can just use a shared reference to achieve sharing in Rust; you don't need a Box or an Arc. Pretty much every shared core data structure in Rust works fine with references with no Arc in sight, and this makes plenty of sense when you consider that the main way you interact with a type protected by an Arc is by extracting a shared reference from it.

Topics Verboten on HN
In my 9 months here, I've noticed certain topics will either be wilfully ignored or quickly downvoted. These are the ones that come up for me:

What's wrong with socialism.

What's wrong with nuclear power.

What's wrong with Elon Musk.

What's wrong with Uber.

It doesn't matter how factual the content, these topics are always slammed. We have a lot of smart people on HN. Why the fear of open discussion on these verboten subjects?

> Unless Elon's statements were actually truthful, it seems that his comments fall under two or possibly three of the above categories. (depending on how one interprets the email he sent to a buzzfeed reporter)

Actually, I think it potentially hits all four:

Pedophilic acts are generally crimes, and the totality of the circumstances makes it reasonable to conclude that Musk meant that acts, not just orientation, is involved, meeting the first form of per se defamation.

Pedophilia is a diagnosable mental condition, and one which brings significant social disapprobation; mental disorders have in some cases been held as being “loathsome” diseases. To the extent that Musk's claim can be viewed as including (even if not limited to) a claim of pedophilia in the sense of the disorder, it fits the second category.

Pedophilic acts are also sexual misconduct as well as crimes, so it fits the third category for much the same reason as the first.

Accusing a professional cave diver currently employed as such in a rescue of children of being an active pedophile certainly seems like it is accusing them of something incompatible with their business, trade, or profession.

(Huh, this case could become a new textbook example of per se defamation.)

The Mormon church has a program where young people out of high school go out and preach the religion in countries outside the US. They don't know what country they will go to until they are told, a bit before they start, so many can't prepare before they go.

They are sent to a language school where in a matter of weeks they are speaking the new language they will need to communicate. They are not fluent but they are good enough to be understood. They will then go on their mission and many of them will be fluent by the time they return to the US, about 2 years.

How is it done? The bottom line is that they have to put in the time and they also need to speak the new language 100% of the time. They can't fall back on their native language when things get difficult so they need to fight through any difficulties. Learning a new language takes time and lots of effort.

I never had any uncertainty regarding where I can use a given entity id in a well designed API. Fix the naming and organization of your API if that's a problem for your users.

Conversely, I often need to log or store API-provided entity ids on my side, and having to parse it out of a URL or store irrelevant URL bytes in my own database would be really annoying.

You're not going to avoid the need to compile entity URLs on the client side either, unless you only make requests to entities returned by the API, which would be a weird constraint to design client code around.

I really don't see the point to any of this.
'It could change everything': coin found may be from pre-1400 Africa
"Never to be wrong" sounds like a big source of anxiety. I think for me it was always to admit that my mind isn't perfect, that it's always possible that the model built from assemblage of facts could be faulty. And a polite deference to opposing ideas.

Some people in corporate politics will walk all over you for allowing such things. But I would call it not being a jerk.

People always mention Aluminum when it comes to recycling, but Aluminum is the best of all the materials.

The vast majority of material is not like that though.

In summary: Recycle metal, not anything else.

> There is an energy saving component to recycling. Aluminum for example takes a tremendous amount of power to produce and recycling reduces that.

Yes, that’s why aluminium is recycled everywhere. Glass, on the other hand, is more of a “What the hell do we do with this?” situation because making glass from sand is cheap and doesn’t have the quality control issues of making it from old glass. That’s why recycled glass goes to making gravel, decorative or not, mostly.

Transport is cheap and most recycling makes no economic sense and wouldn’t even with a carbon tax. Chemical feedstock is cheap, wood is cheap, metals are cheap. That covers plastics, paper and manufactured goods. Recycling is a religious impulse, not an economic one.
