I don't think it's ever a binary question of can versus can't. I think that the disease manifests as a source of internal distractions that are hard to ignore. Think of pain. Imagine trying​ to take a test while someone was jamming a knife into your foot. I'm conjecturing that other distractions work in a similar way to pain.

It has been noted that amphetamines are capable of relieving pain. That makes sense if you conceive of pain as a distraction that forces you to pay attention to it. Amphetamines allow you to concentrate harder on something else.

There are most likely different forms of ADD or "ADD," and perhaps there is a form of ADD that acts directly on the brain's attention mechanism. We don't know anything about how the brain's attention mechanism works, so the idea that it can be​ broken is pure speculation.

There's an app called D-Vasive (no affiliation) that alerts of mic and camera usage on your phone. I've been using it for years, but it's only alerted me in predictable situations so far. I don't download a whole lot of apps however. It’s nice to have as a bit of peace of mind.
I'm not sure what you're comment is trying to say - TARGETING a new API doesn't meant you don't SUPPORT an older API. It just determines backwards compatiblity behaviour. We currently release a product that supports Android 4.1 while targeting Android 7.1.

Also this dashboard is hugely misleading for the HN audience - in western audiences (USA, Canada, EU, etc. - countries HN users are from) we're tracking ~10% devices that are running Android 4.x and more than 40% devices running on Android 6.0 with additional 15% on 7.x - meaning more than half of active western users are running decently modern Android.

I suspect the fact that the Earth itself is an effectively infinite sink of momentum, and space is an infinite sink of energy, has something to do with why conservation laws aren't as much of a thing for climate models.
The real question is why does Android along with most other operating systems distrust the user so much.

If the user were regarded as important facilities would be provided to enable the user to control the applications.

This already exists - our company has been doing this for years, amongst several others.

The problem is a major global 12-figure industry with little oversight or regulation combined with tons of subpar talent and overloaded with politics. Until the major advertisers learn and want to do better, the (good) vendors, websites and users will suffer.
What it's trying to say is that this can be a big problem even if it doesn't affect Android 6 and up. Your own statistics say it can affect up to 45% of Android users.
Asians are proportionally over-represented because programming broadly rewards IQ, and asians have the highest IQ. Men are over represented because they are naturally better, on average, at abstract mathematical reasoning.

There are social reasons as well, but this is the core of the issue.

So this product is still in development. Hence the hardware is ready for regeneration, but right now the firmware doesn't support it yet.

In principle it works by just putting a high charge current capable battery on the DC bus, and simply dumping the regeneration current onto the bus, and the battery will eat it, as the bus voltage rises.

The "Architecture" heading, a bit down on this page explains more: https://hackaday.io/project/11583-odrive-high-performance-mo...
Sure. But from what I understand, sunken military vessels are often designated as graves, since it's too difficult to retrieve the bodies from it.

Both the US and UK seem to protect sunken military vessels for this reason.
3) is interesting. Sensorless operation is common for running motors, but usually doesn't sense position when the motor is stopped, or being moved by external forces.

So if you put a carrier on the power signals, you can potentially sense position, even at zero speed? No need for even Hall sensors? There's a paper from 2001 on that.[1] But it doesn't seem to be a mainstream technique. Are there problems with that approach? If it worked well, you'd expect to see it built into common motor control ICs by now. This paper [2] indicates some of the problems. Detecting the sensing signals in the presence of noise is reported to be hard, especially for small motors. It's a PhD thesis topic.[3] Looking for info about this, I'm finding academic papers, but not IC data sheets.

It would sure be nice to have motors with full positional feedback and only 3 wires, instead of 16.

Having an alternative that works on older operating systems wouldn't help you unless the others in your group want to switch just for you. Network effects win.

It shouldn't surprise anyone that white people are majority in white coutries and that it reflects to working life too.

And why male? Because men like programming and only few women do.

Concurrent programming with Java Threads
That model only worked when people would buy your new software every year. Now a lot of software is good enough, and maybe your competition is even free, and the revenue dries up.
i'll say this again: nearly every small business (startup or otherwise) is a marketing problem, not a technology problem. here are just a few things to think about:

* how will people learn your product exists? how much should you pay for this discovery per potential customer?

* what features must you offer for people to want to pay you? how many of these features can you buy vs build?

* how quickly can you get to market, to reduce costs and risk and start learning about the market asap?

* what kinds of people would want your service? why would they choose your version rather than an incumbents'? if price is your only differentiator, then how many features do you need to be a true alternative? how much support and availability do you need to keep customers loyal?

* how do you create enough trust for potential customers to start to rely on your unknown company/product/service?

* how much should you charge? as others have noted, "rock-bottom" is not a great answer. how much value do you generate for your customer, and how much of that do you intend to capture?

* is SaaS the right revenue model for the type of product/service you're building and the customers you're targeting?

* how will you measure satisfaction and engagement, and generate further value to retain customers?

if you're eager to tackle these kinds of questions, go for it! if not, you probably don't want to start a business, because such questions (rather than the tech) will occupy a large part of your day-to-day.

this is why yc's startup school essentially offers a mini-MBA curriculum, rather than a tech-focused one (these questions are also covered in the core marketing class of an MBA program).

Yes, I am referring to Onyx and others. Onyx is probably the best one, and they will be shortly upgrading to Android 4.4, providing a lower consumption CPU and more importantly HDMI input.

This last feature is a game changer.

I have tried Onyx 13 inch readers, and its a very good experience on technical ebooks, which I get on djvu and pdf formats.

Sexual selection seems like a really interesting case of natural selection having the property of both creating and filling an evolutionary niche.

Through that lens, there's no counterintuitive behavior here, and natural selection isn't being undermined. It's an emergent polarization.

This is an example of the more modern, detachable design. It's ready to use in under a minute.

As a child growing up in the suburbs of Boston, we had something similar in our backyard. It would come out with the summer patio furniture and return the shed when autumn hit. Not only it more eco-friendly, but the long term damage of high-heat is pretty well studied in the scientific community[1].

I was actually interested enough to test this out on my own. During the regular Brooks Brothers 2 for $100 bi-yearly sales, I picked up two identical blue oxford cloth button-down shirts (of domestic manufacture, circa 2012). I weighed them to make sure the oz/in quality was comparable, along with a pretty thorough defect analysis to inspect the quality of the seams, how well the buttons were anchored (they both had anchor points), qualify of cuff/plackets, etc. They were more or less comparable in quality, but I selected the one with more flaws to be used as the 'air dry' (I took a Sharpie and scribed with a red x to denote the 'air dry' to maintain consistency.)

Both of these shirts were washed in the same unit, with the same detergents and had uniform wear patterns (amortized over time at least). They'd get ~3 wears in the winter, and generally 2 in the summer, followed by a wash in cold/cold with on 'medium' agitation. I wish I had pictures to document the evolution, but after ~6 months the color fade became was pronounced to such an amount that I could identify between the two. This fade continued in more or less monotonic ln() fashion as a function of time.

The structural failure occurred on the 'dryer' unit around 3.5 years into the purchase. It failed at the at the elbow, though curiously not due to fabric wear fatigue in a stress-loaded position (i.e. the conventional 'blazer hole'), but the seam that bound the sleeve together[2].

Obviously there's no rigor to this anecdotal story. But any article of clothing that I've got some sentimental attachment to will get air-dried just to prolong the longevity. For those who are curious, the 'air dry' experimental unit was retired after ~6 years of use due to structural deformation[3] of the experimenter.

OK, I could use another example or a hundred ones, but eating a lot of red meat can cost us money. At e minimum increases our insurance rates or we have to pick up the tab if they can't afford.

My point still stands. If it was so ironclad, it would illegal to refuse to vaccinate. Refuse to "care" about your child and you go to jail and lose the child Yet, you can refuse to vaccinate him/her and suffer no consequences. So you have a choice. If I tell you that you do not have to vaccinate, why should I be sued or jailed?

I read the whole article a couple of times, I find it hugely interesting. The part where they wonder if they are taking what could be $57K students and getting $7K students was fascinating, and obvious in retrospect. The answer is no, they are getting $7K students where they would not have gotten a $57K student.

The part about the prof interacting more with the online students was also interesting.

I am simply stating what I am observing and the different ways males and females learn and what motivates them.

I would never advocate not teaching males or giving females priority. Ever! I have a 13 year old son btw. He helps me in these classes.

As my comment states:
"What I am not convinced of is that we should necessarily try and change the boys behavior as long as they are not specifically offending the girls. I worry that this would suppress their instinctual way of being motivated and learning."

I do believe that they learn differently and we need to try and find a way to appeal to both in the different ways they learn and how they are motivated.

I personally think the education system is failing both males and females but that is an entirely different discussion.

The power electronics are built using MOSFET half-bridges, which naturally support the ability to flow current in either direction. This allows current to flow from battery to motor or from motor to battery (regeneration).

In regeneration the motor is actively slowing down the speed (creating negative torque) by pushing energy into the battery. This is achieved in software by regulating a "negative" current, which causes the inverter to produce a voltage that is lower on average than the back EMF generated by the motor. Because the motor is effectively at a higher voltage than the inverter in this condition, current will flow from high voltage to low voltage and therefore flows back through the MOSFETs (and MOSFET body diodes) into the battery.

This is a bit of an over-simplification as brushless DC motors are actually excited by an AC waveform so the current is constantly reversing each half cycle, but the principle remains the same.

This article touches on, in my opinion, the 2 great problems with non-fiction reading nowadays:

* Deciding which book to read next out of the seemingly infinite decision space (which book is optimal?)

* Reading books "well", such that you truly elevate your level of understanding of a topic to that of the author, and then remember what you've learned.

Notably, I think "Read More Books", the title of the article, is more of a symptom. If people could choose the _right_ books and then read them satisfyingly enough to truly become smarter and wiser, reading would be such a great deal that no one would have the problem of needing to read "more".

What's craziest is that these problems are the same ones readers faced centuries ago. Reading hasn't evolved at all! People still prefer reading physical books in the world of the internet and data science. And how do readers choose books? One-off recommendations from people that they may or may not trust.

I think with technology we can do a lot better. Specifically, I've been hacking on solving the two aforementioned problems with books such that we can read and learn like it's really 2017. Would love advice/conversation with any reading-inclined HNers! I'm tristan@rekindled.io
Nothing in iOS prevents an app from using the microphone in the background - I use apps that do it all the time. When I do however, there is a big, obvious, red bar at the top of my screen to remind me/let me know that it's happening.

I developed a kind of meta programming pattern and supporting library, based on Redux, called Immuto, to get absolute and complete static typing (via TypeScript) and minimal boilerplate, also referentiality and modularity (cursors that accepted actions). It was fun, but ultimately pointless, as it was never as straightforward as using the automatic observable approach that I'd learned from Knockout.js. Then I heard about MobX (which is the same ideas from KO but better implemented and without any quirky UI templating thrown in) and so now I used that.

Also I use my json-mobx library to get serialisation and undo/redo. Example: https://github.com/danielearwicker/baltar
Come on it doesnt say "unknown reasons" it says the "It is possible the discrepancy is due to the limitation of javascripts 64bit FP numbers rather than subtle algorithmic or physics error"

70k km / a year (on a billion km long orbit) was a lot closer than I had hoped for, considering its a 64 bit newtonian model. But this is beside the fact that having worked on the project a fair bit, I understand that any model adjustments to conserve energy or momentum are non-physical 'fudges' to correct deficiencies of the model. There are no laws of physics dedicated to adjusting energy, momentum, information in order to conserve them. They are conserved by a mathematical correctness of every physical law - a proper account of that eludes me, but it is certainly explained somewhere.
I've been trying to read more books in 2017, and it's been going well so far and I've read 24 books since January.

The two things that have made the difference for me are:

* use the library! I only paid for 1 of those 24 books. Of the others 1 was a physical book from the library and the other 22 were library ebooks. I rarely find things I want to read that they don't have in ebook format (although often you need to 'request a hold' and wait as they can only loan out each copy to so many people at once). For context, I'm in Austin, TX

* make reading a deliberate evening activity. I used to only read when I was in bed and then be frustrated with my progress. I've started reading on my lunch break at work, and also in place of other evening activities (TV, internet, guitar etc). If I do 30 mins at lunch, an hour in the evening and then some in bed I can finish a reasonable length book per week.
