Yes, of course. But toy helicopters have been around for a lot longer than quad-copters have been popular. And I've not seen a lot of people using single-rotor RC helicopters for filming and delivery (I'm sure there are some ...).

My point is that multicopters are a lot simpler mechanically. No articulation, no transmission, just propellers on an electrical motor, controlled by pure electronics with no mechanical components in the loop except the drive coils.

Arguably multicopters are easier to control automatically (with modern electronics), though that wouldn't be THAT big a factor today, I guess.

Also electrical engines can deal a lot better with variable load and RPM. Multicopters with combustion engines (driving the rotors directly, not through a generator) seem to be quite uncommon.

Still, if multicopters are supposed to be routinely used in the presence of people, they need similar standards of maintenance and failure control as would bigger aircraft, be they manned or unmanned...
Actually most Linux users are blissfully unaware that Linux overallocates memory and of those that know about it, very few understand the consequences to applications (such as data corruption or data loss). I doubt anyone who fully understood the consequences would want to run their infrastructure on something so unreliable and I doubt it because it's logical to me that they wouldn't.
People did challenged hate speech on 8chan. What happened is that those who challenged hate speech on 8chan lost in following fights. One factor is that chan structure favors bad-faith actors and arguments, favoring inflammatory emotional ones. But the other fact is that bad-faith actors and arguments of the other side lost too.
It's highly correlated with pilot experience, and it's not monotonic. Pilots with 20 hours are pretty safe because they are scared of everything. Pilots with 2000 hours are extremely safe because of their experience. Pilots with 200 hours are quite dangerous because they're complacent and overconfident.

No. You need a heart and some minimal level of competence.

If you have that, there are developed countries doing a good job of reducing the incidence of homelessness.

In the US, we spend insane amounts of money on care programs for the homeless, so much so it would literally be cheaper to just pay their rent. At least one hospital decided to do that (for some of their most expensive cases) as a means to lower its expenses.

Two things that would help enormously in the US:

1. A healthcare system that works.

2. A housing supply that meets the needs of our current demographic instead of being designed to only serve upper class nuclear families.
Interesting. From the source article [1]:

> [...] they would essentially be "dev devices." Think of them as iPhones that allow the user to do a lot more than they could on a traditionally locked-down iPhone.

It sounds like Apple might provide vetted researchers with development-fused devices [2]. In an official capacity, these have only been mentioned once - during a Black Hat talk by Ivan Krstić [3].

This already exists: applications can receive memory pressure events (such as the system reaching "medium" level, where you may want to start freeing some caches) via /sys/fs/cgroup/memory/.../memory.pressure_level. See https://www.kernel.org/doc/Documentation/cgroup-v1/memory.tx....
Maybe I will try it, but in my case I run them isolated under another user account so it means that I will have to run several instances of a browser (but I'll try to compare the memory usage). Because I don't want them to install cookies and track me across the Internet.
What does it matter if they were meeting someone or not? The question is whether they were paying customers or not - and they weren't. Maybe they were all going to stand in line together and order something. Maybe they were just going to use Starbucks as a free meeting place.

I don't think calling the cops on them was the right thing to do if they were denied use of the bathroom but otherwise weren't making a scene, but I don't see why potentially being a customer in the future would give you privileges reserved for customers currently.
Still waiting to get mine. I registered my first domain name from my national provider, and always wanted to move the domain aboard to the U.S. or a European registrar, however, the bureaucratic process of initializing a transfer is ridiculous. It's not an important domain name, so I decided to take the risk and allow the domain to expire, so I could re-register it. Unfortunately, the dropped domain was instantly caught by a broker.

Not necessarily. For one, increased yield doesn't always result in lower prices, because the free market generally isn't that free (most of our agriculture is heavily subsidized by the government). Another problem is that access to nutritious food is extremely limited for poor people, for a variety of reasons. Overhead and supply chain economics influence whether local businesses can survive. Marketing/advertising and industry pressure on politics increases the likelihood that cheap, non-nutritious, shelf-stable foods will be more prevalent in stores. And then there's the general self-medicating-through-salt-sugar-and-fat cyclical effect, and overall lack of education on healthy eating and cooking. Even when you can find it and afford it, poor people have less free time to cook.

Rice is a food that is shelf-stable, cheap, and (when enriched) provides a bare minimum of nutrition. Reducing the already-bare-minimum nutritional level, or increasing the heavy metals already found in many varieties, will have a significant effect on already vulnerable populations.
I was to a couple additive manufacturing exhibitions and conferences, and generally the people from the metal 3d printing industry seem to call all laser pointing devices "galvanoscanners", regardless of actual construction.
Most homeless services here follow the "beggars can't be choosers" egotism of not attending to people's actual needs but rather looking down their noses on them, treating homeless people like criminals or make them jump through hoops like show animals.

For example, most of the doctor specialist services here have a "full" waiting list just to schedule an appointment and force people to call at a certain time in the morning for a few spots on said list, like animals jockeying to win the lottery.

Oh and the amount of food and cash aid is abysmal, not enough to feed or clothe anyone.

Most services demand either employment or only apply to certain groups, leaving many people to fall between the cracks.

The "social workers" are arrogant, obnoxious bureaucrats who don't listen to their clients but instead hold their aid over their heads and order them around without offering any solutions, strategies, resources or actual help... just judgement and control.

And it takes years to get disability status reviewed and longer to get housing. There are at least 1500 people living rough and 500 people living in vehicles in the area.

Android sends low memory events and kills processes based on heuristics.

I came to the comments to talk about this, was totally hoping to scroll down and find a section about software in the wikipedia article.

True flying cars exist. I watched one go from car mode to plane mode, fly around, land, and drive off the runway in car mode again at EAA in 2013. They work and they meet all the expectations we had when we were kids. Except one: They cost over a quarter million dollars. Everybody said we'd have flying cars, but nobody told us only rich people would be able to afford them.

TIL. I should check out Rectangle:

> Spectacle used it's own keyboard shortcut recorder, while Rectangle uses MASShortcut [1], a well maintained open source library for shortcut recording in macOS apps. This cuts down dramatically on the number of bugs that were only in Spectacle because of the custom shortcut recorder.

Anyway Linux won for now, but Solaris lives on vicariously through illumos and SmartOS, which handle this the same way as Solaris does (it's the same code) and the codebase is very actively developed, so it's not over yet no matter how much Linux is winning now: I'm waiting for the folks to figure out just how shitty Linux is under the hood and the fact this is a topic on HN tells me it's starting to happen as people gain more and more experience. Linux won the battle but with such shitty code underneath winning the war as history will judge it is another matter entirely. Meanwhile SmartOS continues to be developed and works correctly in these situations.
I don't want to appear to defend 8chan here - but I don't think your critique is apt.

For one, the people on 8chan are absolutely a hated minority. That's largely why they're getting banned from the internet. Mainstream figures aren't coming out in favor of 8chan, they're calling for it's dissolution. Saying you visit or enjoy 8chan in polite company would likely be a faux pas if anyone even knew what you were talking about.

Of course, pretending to be a hated minority may be a rhetorical tactic - but that doesn't make it untrue. The Westborough Baptist Church may have experienced enhanced camaraderie from being almost universally reviled - but that doesn't mean they weren't, in fact, almost universally reviled.

"Authoritarian" also seems like a poor description. The boards are anti authoritarian in that they have lax moderation. There isn't a punishment for unwanted opinions - you can't be downvoted or shadowbanned. People can't even judge your future posts by the content of your previous posts because everyone is anonymous and without a post history. Banning is by ip only, and easily avoided, and there aren't even accounts to lose. 8chan is much more anarchic than authoritarian. I'm making that claim based on their structure rather than their political ideology.

The idea that Silicon Valley is not left wing also strikes me as highly suspect. For example, in the last Presidential election Clinton received 95% of Silicon Valley donations compared to 4% for Trump [1]. There are other, similar reports, for specific companies and different elections, but everything I've seen slowed they skew heavily left.

I'm aware that there are conceptions of "left wing" where Clinton wouldn't really count as left wing, but so long as we are discussing American politics I don't think those alternate conceptions are relevant. Clinton is clearly further left than Trump.

You'd want a system where each citizen receives an ID/key, and there is no way to who a particular ID/key voted for, but if you know your ID/key, you can look up whether you voted. This should deter anyone from voting in anyone else's name, since they'd be likely to be exposed if they did it at an impactful scale.

The only other way to forge votes would be to invent new people that don't really exist, or maybe piggyback on recently deceased people. These are both problems that should be fairly straightforward to address if you have decently efficient administrations keeping track of things.
> The reasoning is very simple: any form of swapping is completely unacceptable on a production server because it randomly and massively degrades server performance. If you have a cluster of stuff and one node is misbehaving like that, you kill it because that is completely unacceptable. If that is a regular thing, your servers are obviously mis-configured in some way and you fix it by provisioning more hardware or tweaking the limits.

A small swap space (~ 1G on a 64+G ram server) is a reasonable backstop against a slow memory leak. Assuming you don't have filesystem pages evicting anonymous pages, swap use is a clear indicator of too much memory use and points you in the direction of something to fix; and gives you a little bit of time to fix it on the running system. As long as swap is very small relative to ram, it's not going to enable thrashing -- a big leak or burst in use isn't going to fit in swap and you're going to be dead anyway.
When I read about companies implementing chat auto-moderation, I'm not sure whether to be disappointed at the utter pointlessness (coupled with invasiveness) of such exercise, or to applaud them for promoting kid creativity.
> I don't see a way to avoid it happening

Civil society outnumbers spooks by how much, and who needs who, who is paying for who? Simply withdrawing support and tax money could end it rather quickly.

I can't tell you how to organize people to do that, but it could actually just happen anytime, just a fluke, everybody wakes up in the morning and thinks enough is enough. High-tech requires constant, expensive maintenance, It's not like, say, a giant stone structure you can leave unattended for a few years or even decades.
> If you don't have enough memory left to cache effectively, that just means things like memory mapped files will get a lot slower.

Understatement of the year. If you can't cache your memory mapped executable pages, your system will be just as slow as in the nightmare swap scenario.
You don't digitize elections for efficiency. You do it for security. The idea that paper ballots are a secure form of voting is ridiculous. The only reason people think that they're secure is that they're so profoundly insecure that we have no way of auditing them effectively and so never uncover anything that may be happening to them.

Not to mention the fact that access and efficiency are in fact forms of election manipulation. The inefficiency of the process keeps people from voting who otherwise would. That has political consequences and is absolutely used as a means to cause outcomes that otherwise wouldn't happen.

How is Trump in any way a 'fascist'? What do you think actually characterises fascism?
You can't have an anonymous system that simultaneously allows meaningful verification: if there is no way to tie me to my vote in the system, then there is no way for me to prove that my vote was misrepresented to anyone but myself. Even if there were, there is no way for me to prove that my claim about my vote is correct. Even if many people come out claiming that their votes are mis-represented, there is no way to know whether that is a sign of errors/tampering with the system, or a concerted campaign to try to put the election in doubt.

Any system which foregoes physical proof of voting as a base for the count, relying instead on after-the-fact verification, is open to this problem. A complex system, whether software or even mechanical, can never match this level of confidence.
If skateboard deterrents refers to the nubs which are put on the railings for stairs, I'd say those come with more an ethos of, "This object is for the public to walk up stairs more safely. You will not use it as a ramp-bar. That both makes it unusable for anyone while you are doing that and also causes it to break down from friction more quickly."

Since there isn't really a fundamental human need to slide a skateboard down a handrail, I don't think it really counts as "hostile". It just represents, "I've agreed to provide a certain level of maintenance for this public handrail. Not enough to handle repeated skateboard friction."
An update to the definition of Scrum is coming. What can we expect?
It uses pyquery: https://github.com/gaojiuli/htmlie/blob/master/htmlie.py
You could also add a second layer of security here pretty easily. People would probably need to be given a printout with their hash on it. To avoid this receipt being proof, that receipt would include a large number of hashes with various voting combinations also shown. The voter knows which hash is his, but nobody else does. And he's free to claim whichever one he likes for himself.

To solve the issue of first voters (when there would be no other valid hashes for their printout) simply seed all candidates with a billion votes to start. Which hash is real and which is 'fake' is irrelevant since all that matters is the sum total of which we know 1 billion are to be removed.
This isnt just games. Lets be frank. We can become addicted to anything given the right physiological triggers.

Capitalism has optimised itself to the point where you are nothing more then meta data. Its at the point where a team of accredited people can sit infront of the meta data, and your product, and they can design ways to trigger dopamine responses.

Putting "any" kind of "modern product" in your childs hand will lead to one thing. Now put a connected device in their hands, and your putting your child in the hands of unlimited amounts of teams, using unlimited amounts of tickery, to earn profit from your child.

Now add back in a dynmically manipulated game environment, where these tools are utilised by predators to exploit your child for their version on profit.

This is the challenge of being a modern parent. Junk food, everywhere, all the time.

I live in an Asian city of 13 million people. Only the exceptionally rich own cars here. (There is a 100% import tax on top of the vast difference in incomes between here and the US.)

Millions of families raise children here without a car just fine. They would be amazed to learn that you think it is impossible.

Even if they moved out of the city, they still wouldn't be able to afford a car, anyway.
I don't thing this is what codebolt was talking about.

If you can one kid - there is no problem really. Walk him or her to school in the morning, ask grandmother to bring them back etc.

When you have more than one - it is entrily possible they will end up going to different schools and after the school one of them had to go to the music shool and the other one to his hockey team or something etc etc. You simply can't do this without a car.

I was the only child in the family so we never needed a car for this kind of scenario, plus we were living in a relatevely small city (450k), so public transport was more than enough for me, but this is not always the case.

>and then walk a couple more blocks to work.

yeah, now imaging you have two of them going to two different schools, each 40 minutes walking distance from home, different directions and your office in somewhere else too.

How can that be right? 20c is on the low end of room temperature. So a plant is actually bad at photosynthesising when it’s warm and there’s the most sunlight? Why? Wouldn’t this mean greenhouses are BAD for plants?

Germany: Most (all?) cities have special tickets for pupils. There are separate bus lines in the morning which pick up the pupils from the bus stops and take them directly to school.

In the afternoon there are some special lines too, otherwise you just take a normal line with your pupil ticket.

That's at least how it worked in my time, like 20+ years ago.
