How high a frequency do you have to inject for sensing? Much higher than the power chopping frequency, presumably. Megahertz? Harmonics from the PWM drive are going to interfere. I can see why separating signal from noise is a problem, and why mating a motor and a controller isn't going to be plug and play.

Larger drone prop motors seem to be mostly permanent magnet brushless. Often the stator is on the inside, and the rotor is a rotating shell carrying permanent magnets that fits over the stator. 12 coils and 14 permanent magnets is a common configuration.

Other drone motors look more like standard motors, with an outside stator and an interior rotor. Some of those are definitely permanent magnet.

Here's a good overview.[1] If you wanted to repurpose such motors for
industrial control, the main problem would be cooling. They're intended for
use with the prop blowing air through them, so they can dissipate much more
heat than most motor configurations. Slow speed, high-torque operation would
probably overheat them.

You can't turn Gatekeeper off anymore, at least not without using the command line. You can bypass it on an app-by-app basis by just right-clicking an app and selecting "Open" there, which is what you'd have to do if you're downloading apps like Handbrake.
The real problem is that you're trusting binaries you find on disparate websites.

If you want to avoid these sorts of compromises, use a package manager or check the hash of the downloaded file against one that you trust.

No it's not. In this case 1Password wouldn't be compromised, since having access to the system doesn't mean you can decrypt the passwords.

With OS X keychain(and browser) unfortunately, if your system is compromised, you can decrypt the password store.

Password managers aren't implicated in the compromise of the OS X keychain or your browser... this is FUD.

Your browser's native store is probably unencrypted [1], and the OS X keychain password can be snatched with a clone of the native password prompt. Neither is true for any respected password manager. They keep you safe.

> However, says Dr Dines, one thing's for sure: "If these women [who watch violent porn] have been abused, [they] are actually digging the trauma further into the firing and wiring of [their] neurones, driving it further into their limbic systems, and porn delivers a massive hit to the limbic system because you're watching someone going through the same trauma you did."

I'm not a Dr of any kind, but I think this is only true if they are associating the things that are happening in the porn with something negative when watching it. The whole theory behind EMDR [1], as far as I understand it, is that you can re-associate negative memories with more neutral (or positive) feelings. That might in fact be what some of them are doing: re-associating a negative memory with something positive, which might have a therapeutic effect.

>or a brand that brings value to you

I have, exactly once in my life, connected with an ad in this way.

I remember it vividly, because even at the time, it struck me as amazingly strange an ad would actually be anything other that pointless noise.

I'd been house sitting at a friends place for a week, and so had been to all the takeout joints in the area several times. I didn't really want any of the options again, but was kinda hungry for lunch. At that moment a subway ad came on TV, and I remembered that there was a tiny subway tucked away off the main street, so I went there for lunch.

That's it, that's my story of ads putting me in contact with a brand that brought value to me. It happened once, and only once, and it happened at Norwood, South Australia.

I feel like I could have dug deep and lived without that brand connection.

Wearing a Diaper After a Creampie
Whether you're Straight, Gay, or Bi. Wearing a diaper after receiving a creampie vaginally or anally can be a good idea to keep your lovers cum from getting all over the place. I often wear Bib Overalls without underwear and have for a long time now. So such is often a good idea.

With a bus/truck they remove the bodies (usually). These ships went down with people in them and are graves. There is a difference.

It would be like you being buried in a coffin in a stone church and then one day someone decides they want the stones and they take the whole church ... including you :) As a relative i would be pretty pissed about that too.

If they were correctly identifying bodies and returning them to their families for proper burial etc... then it might be ok to reuse the steel.

The communities around Ruby, Python and Javascript are probably more oriented toward professionals than is ideal for a new programmer. While there is good content for beginners, there is also a mountain of mediocre and obsolescent content and another mountain of content that is only partially related, e.g. Rails, TensorFlow, React respectively.
TL;DR

"...a discredited theory spread through the local Somali community, by meetings organized by anti-vaccine groups. The activists repeatedly invited Andrew Wakefield, the founder of the modern anti-vaccine movement...

Anti-vaccine activists defend their position and their role, saying they merely provided information to parents.

“The Somalis had decided themselves that they were particularly concerned,” Wakefield said last week. “I was responding to that.” He maintained that he bears no fault for what is happening within the community. “I don’t feel responsible at all,” he said.

...activists started showing up at community health meetings and distributing pamphlets, recalled Lynn Bahta, a nurse who worked with Somali nurses to counter MMR vaccine resistance within the community. At one 2011 gathering featuring Wakefield, armed guard barred her, other public health officials and reporters from attending."

That seems likely, although I strongly doubt the requirements are that stringent. The issue with bombs isn't just that they release (and create!) a lot of radioactive material, but that they pulverize that material and push it high into the atmosphere where a lot of it spreads around the world. Whatever radioactive material might have escaped from something like Chicago Pile 1 would have stayed local.

This. That's why infographics are fun to read and look at. I'm not saying that books should be in the form of shapes and infographics, but I think we should leave this traditional way of publishing books as if they're HTML pages. More CSS in the books would definitely go a long way.

On HN driving societal wedges? I really don;t understand your comments at all.

Let's start fresh:

1. Vaccines apparently are not mandatory. You can vaccinate your child or not.

2. Someone that's telling parents not to vaccinate, shouldn't be going to jail, because he's not doing anything illegal (see point 1).

3. The state should make vaccines mandatory first, which IMO is the correct choice.

There's no FUD or anti-vaccine thing, simply saying that as long as vaccines are optional, people should not go to jail for saying don't vaccinate.
It's worse than that. Because better solutions were "hard" or long-term and competing organizations couldn't agree on shared standards, they took an application and protocol designed to traverse documents, and built on complex hacks until it essentially became a pseudo-operating system, which now not only drives part of the global economy, but also changed the type and quality of information that most people receive.

Which package manager? :P
Those ads form the 1950s would be inneffective for most advertisers right now. Only "mcdonalds size" companies can afford generic advertising like that. With online ads anyone can spend $100 and it can still be very effective.

Your problems with repetitive and irrelevant ads isn't because the marketing industry is bad, its because some advertisers don't know what they're doing and run bad campaigns.

I agree that the industry will change - but only when the consumers force it to. Adblockers will eventually be widespread, and marketers will adapt to it with something else. The ads you mentioned you like aren't scalable - you can't spend $1000 in the next 20 minutes with those ads like you could with display ads right now.
The more I read this the stupider it sounds.

"under almost no circumstances does is colonizing another planet the best way to adapt to a problem on earth...

...Even if an asteroid were to strike earth it would remain more habitable than mars. For example, consider the asteroid that struck the earth 66 million years ago creating the Chicxulub crater and wiping out 75% of plant and animal species on earth, including the dinosaurs. Well that disaster still left 25% of species that survived, all of whom would die instantly on the surface of Mars."

This insinuates that surviving the aftermath of a Chicxulub event is what threatens us - but it isn't the aftermath, it is the event itself.

Best quote: "Even though I am not an expert on space, physical sciences, or basically any relevant field, I can tell that this is obviously true. Maybe just it takes an economist to see through the nerd fantasies."

LOL!
> most biologists think that evolution selects

It's my understanding that gene-centered view is the main view among evolutionary biologists.

Multi-level adaptation seems to have fallen under lack of evidence. Evidence from nature, mathematical theory, and evolutionary simulations seem to back up selfish gene theory. There are still people like David Sloan Wilson who work on it.

And yet, it happened :)

And the senior engineers at the company looked at it and confirmed it was a compiler bug. Their best guess was that something about that part of the code was putting the compiler in a funny state, causing it to skip that particular `else` branch.

We reported it to Microsoft, but never heard anything back.
I had to switch to another computer to see screenshots, I couldn't see them either from Chromium or iCab under iOS 10. Whatever fancy stuff they're trying to do on their site comes with a significant(ly irritating) browser compatibility cost. The iOS screens themselves are also pretty mediocre. I do not think stuffing them into that iPhone frame is at all helpful in making them informative, and they don't cover a lot of important basic questions I have. I guess I'm supposed to go to one of the linked other sites for more information but I consider that a significant fail in a product, IMHO their own web page should be the authoritative source that can answer most of my questions about core basics of specs and interface.
That's awfully optimistic of you.

First of all browsers are committed to backwards compatibility.

Secondly, there's huge amounts of Javascript written right now, nobody's going to throw away billions of dollars worth of investments. People complain about Cobol written in the 60's, when the programmers counted in the thousands. Javacript today is written by millions of programmers.

And thirdly, Javascript evolves, as do browsers.

> why not use three cameras simultaneously, each from a different angle, then classify the three images? Those cameras must be nearly free in cost.

Because you really only need one camera (and two mirrors).

> Also, to get more training data, what about setting up a puffer to blow the part back on the belt and tumble it?

That's an interesting and novel idea. It probably will not work because the difference between the heaviest and the lightest parts are such that you'd blow most of the parts clear off the belt. Also the camera is sampling fast enough that the part would end up imaged in many positions without the ability to stitch the parts together again. But interesting.

> And question: do you normalize out color at any stage? As in, classify a black and white image, with a separate classifier for the color?

No, but I am considering using HSV or LAB as the colorspace to see if that improves accuracy or reduces training time to get to a given accuracy.
That whole thing will wane like that electricity fad did. You will see - in a 100 years, nobody will have a use for all that modern hokus-pokus.
I remember once from undergrad the saying '"obvious" is the most dangerous word in mathematics.' Seeing how something could be true is dramatically different from identifying and defending that it is true.

It's dangerously easy to say "oh yea, makes sense, natural selection happens by mating so if mates choose club wings, I get it. Obvious." But Prum's trying to go a step further, and test just how far out of balance and arbitrary the mate selection part can be from the direct do-not-die part of evolutionary fitness.

He proposes that we can differentiate between these two by considering that the club wings aren't actually indicators of higher direct fitness, because they hurt the ability to fly, even among females that have no need for such shenanagins. I'm not sure I totally agree with or grasp that, but at least it's an attempt to further understand and test the idea.

I'm frankly surprised by comments accusing a well established evolutionary biologist of severely misunderstanding natural selection. The author has spent his career, among other things, investigating mechanisms of evolution, and identifying and performing tests to assess their relative importance to a particular species (here's an example: http://prumlab.yale.edu/sites/default/files/prum_1997_phylog...).

You might consider whether your objections are addressed in his work not aimed at the lay population, and that your criticism really just amounts to "He wrote this at not exactly the right level of sophistication for me." Maybe that's true, but it's a pretty boring claim.

I'm sure that is what you believe but that doesn't make it true.

> 2) and 4) and 5) are strawmen. It is -in fact- possible to understand the fundamentals and look things up.

I've never met an engineer (or any professional implementing complex processes) who simultaneously grasped the fundamentals of all areas where they needed to possess competence from memory. (Yes, that includes myself in case you are wondering.)

On the other hand, if you thought modern browsers are bloated, just wait for everyone to compile their runtimes on top of WASM.

The OS X keychain is a password manager, right? Just as your browser. Your browsers native store is probably encrypted, see your own source.

How would a respected password manager guard against an infected machine?

Take keepass as an example, they state: The actual problem here is running specialized spyware (as the same user and with the same rights, like KeeFarce assumes). If you are doing this, everything is over. An application cannot protect itself in such a case; all modern PC operating systems (Windows, Linux, ...) http://keepass.info/help/kb/sec_issues.html#keefarce

Also, at the bottom of the page: Neither KeePass nor any other password manager can magically run securely in a spyware-infected, insecure environment. Users still are responsible for the security of their PC.
So you're basically saying that the current web is a reflection of human kind, with all its flaws and quirks? :)
What about them? A GRB that takes out Earth would cook Mars even more thoroughly due to its smaller size.

I think in practice we will colonise mas but no more than we are colonising Antarctica. The ITS will make going to a Mars affordable and there are good scientific reasons for wanting to do so. But my most optimistic scenario is that we'll have small bases on Mars for at least a generation testing out technology before well even begin to be able to dream about making such a station in any way self sustaining, even just in food, air and water let alone anything more complex.
