You don't have to keep track of it. The OS will tell you when you have 10% left which is about 2 days of use and it quick charges in about 20 minutes to give you a month's worth of use. It's a non-issue.

FWIW, the reason it's on the bottom (according to one of the engineers) is because they didn't want people to leave it plugged in all the time while using it as that severely degrades the lifespan of the internal battery. Forcing people to plug it in while not in use apparently extended the lifespan by something crazy like 20x.
It's not "endlessly scrolling", it's scrolling for the few minutes you're looking at it. Nobody scrolls FB pages - or even downloads updates - for 24h in a day, and it would be absurd to limit speeds as if they did.
> Encryption that breaks if someone other than the authorized parties observes it. Something which isn't possible with "traditional" encryption.

As stated, this isn't possible with encryption enabled by quantum key exchange, either, nor is it an intended goal of the procedure. Quantum key exchange empowers integrity in the cryptographic key exchange process, but it doesn't intrinsically do anything to empower confidentiality (encryption) or authentication. If you successfully share a key with another party using a channel established via quantum entanglement, you will be (theoretically) capable of discerning with certainty whether or not there has been an attempt to record the key "outside" the channel.

The quantum innovation ceases once the key has been successfully shared. The ciphertexts encrypted with a key shared via quantum key exchange are just like ciphertexts encrypted with a key shared via traditional key exchange. They will not "break" if observed by an unauthorized party; in fact, there is no way to endow a ciphertext with that property. Either a party has the correct key or the don't, but the ciphertext will not "self-destruct" or cease to become usable if the incorrect key is used.

I feel this is an important nit to pick because even if you understand this, others reading your comment might not. Conceptually speaking, assurance of secure channel integrity is very different from assurance of confidentiality. It would be more accurate to say that in a quantum channel, you could exchange information in such a way that it cannot feasibly be read or tampered with; however, if the ciphertext were extracted from that channel, it would not be meaningfully different from a ciphertext extracted from TLS.
Everybody is mad/disappointed at/by the NPM for their handling...

Does this have any real impact on the NPM package adoption though? There is no alternative node module package directory, is there?

It seems like any action they could have taken would have had exactly the same effect (well, maybe some prospective products don't adopt JS backends, but you have all webpack projects locked in pretty tight, right?)
Check out the 34C3 talk on adversarial AI. They found that the percentages of fooling are still high if one gets the adversary model completely wrong when designing the attack generating network, so it seems surprisingly stable.

I always imagined that a steep learning curve was metaphorically like a hill that took increasing energy with increasing slope. Turns out that the axes of a learning curve are learning on the y axis and experience on the x axis. So if the curve is steep, you learned stuff quickly. Many other good examples in the article. May the steep curve be with you.

> synthesizable core

That means two things. One, that the design description ("RTL code") can be pushed through synthesis and place-and-route tools and turned into gates. This is useful for putting the design onto an FPGA or getting a piece of silicon (ASIC chip).

But it also means "not custom", as in, the gates are not auto-generated from "synthesizable RTL" but rather than laid out by hand. Full custom can eke out some improvements over synthesizable logic, but it's also more expensive and can preclude testing out designs on FPGAs before manufacture.

Most modern chips are mostly synthesized with some of the more critical components (and more "regular" structures) handled using custom or semi-custom methodologies.
We learnt this in March 2016 when one developers got a copyright claim and had to remove their package. [2] Why is it even possible to remove a package?

The earlier problem you mentioned didn't seem to be about copyright. But if it had been, the answer to why it's even possible to remove a package is: because if you don't and you knowingly continue to host copyright-infringing content you can expect a very large penalty in court.

Why is scientific inquiry bad?

The first step in scientific inquiry is identifying the problem. Since that hasn't been done -- just as it wasn't done in the other examples cited -- that suggests the motivation for "investigation" is politics rather than science.

My favorite example is probably the video game moral panic. Nobody seemed to care that the juvenile crime rate took a steep turn down right around the time FPS games began making the news. That wasn't an example of "scientific inquiry," it was a politically-motivated witch hunt. What, exactly, is different this time?
A potential application of this could be some kind of “privacy sticker” that you’d wear on your hat or your face in order to disable automated facial recognition systems.
The annoying thing (to me) is, I think it would be awesome to have a study (or studies) of how X [fill in X for the appropriate decade] affects/interacts with children. But not just children, how about people of all ages?

No but if you treat the "key exchange" process as a one time pad key and simply xor it with the message it doesn't matter that the actual ciphertext can be intercepted, since it's impossible to decrypt it. The only catch is that you would need to delay reading the "key" until the last possible second, and of course side channel attacks are still possible on both sides.

Now with how complicated and costly creation of the entangled particles will be, I'm assuming that usage like this will be very very rare, but it's still possible.
Ask HN: Travelling to the US. What can I expect at border security?
I am travelling to the US from Australia next month on a solo holiday (not business) trip. Though travelling on an Australian passport, I am of sub-continental heritage, and was born in a Muslim country. I am also highly active on multiple social media channels.

My question is: Does US border security still ask for sign on information to social media? If they do, what is the best/legal response to that? I have nothing to hide, but want my privacy respected, and don't want to divulge my FB/Twitter etc. password as I use those apps to authenticate to _other_ services which I use for running my business, so there is a risk of business IP being exposed if someone else has those logins.
No, it's just one particular method of creating entangled pairs, e.g. there are integrated semiconductor devices that can be used to generate them using other physical effects (but AFAIK SPDC is what most people use in practical situations)
>> for greater responsiveness and a higher benefits realization ratio, “product-mode” is a more effective way of working than projects.

> This is a sweeping statement.

It also can quickly degrade to being horribly untrue. A product team justifies its headcount and activity decisions in a silo.

The product owner justifies a budget that translates roughly into team size and then sets to work on whatever satifies the objectives they've been given.

But a recurring truth of large organisations is that silos evolve to justify their own existence and size. You keep having $N people costing $X working on product $T because the product owner justified it to someone, not because it delivers the high benefits realization across the organisation.

The article's "New Silos" section just sweeps this to the side with "but it's better than the old silos".
And it can be, but isn't definitively so.
Any autonomous unit runs these risks, and unless the unit has its own P&L (with a real source of income, not just money taken from other people) preventing it from becoming bloated and serving its own desires (over the objectives of the organisation) takes hard work and requires proper oversight.
As visualizations these are pretty, and relaxing. They're less informative than piano-roll displays. The space taken up by the '3rd dimension' pretty much limits them to solo instrumentals.

"Virtue signalling" mostly means: thinking that the public generally thinks that certain things are good and certain things are bad, and so—whether or not you think those things personally—you know that it's good PR to support consensus-good things and be outraged by consensus-bad things.

Virtue signalling is at its most stark when the "good" thing is known to not actually be good, and yet companies do it anyway because they know that the public mistakenly believes it to be good.

For example: agro businesses virtue-signal by using "pesticide-free" processes—which aren't actually "pesticide free" in the spirit-of-the-law sense, but rather just make use of alternative chemicals as pesticides that aren't classed as pesticides by the FDA. These alternative pesticides are worse for the crops, and for your health, than the finely-tuned ones that get sprayed on regular crops. The businesses are signalling virtuousness by doing something knowingly anti-virtuous.

Another example (this time more in the editorial vein of the OP): governments and nonprofits love pushing for increased residential recycling. It's commerce and industry that generate the vast majority of waste; residential waste accounts for less than 10% of all waste, and recycling already has decent-enough take-up among residences that the additional ROI on residential recycling advocacy is actually negative. (I.e., we've passed the point where the marginal person affected by recycling advocacy actually helps the system by recycling; the people being reached by advocacy now are people with high-enough-paying jobs that it has more benefit to let them spend the time they would spend recycling working, and then tax their additional income and use it to pay for sorting facility workers.) But it's consensus-virtuous to preach the individual responsibility to recycle, so companies love taking part in spreading this advocacy. (Often in hypocritical ways: they'll give their office buildings separated waste containers so that the employees can feel better about having recycled—and then dump all the containers into landfill, because that's more cost-efficient.)

Yes, this is pretty much the basis to quantum key distribution protocols, and probably one of the first studied uses of quantum information in general. Consider BB84 (http://www.cse.wustl.edu/~jain/cse571-07/ftp/quantum/, https://en.wikipedia.org/wiki/BB84, apparently the first quantum cryptography protocol), which would allow the transmission of a one time pad with an any eavesdropper being unnoticed with provably exponentially decreasing probability in terms of key length. The one time pad can then be used to securely transmit data.

Thus it is possible to transmit arbitrary (classical) data with exponentially decreasing probability that we do not detect an eavesdropper. Alice and Bob can communicate with each other knowing that there is provably pretty much no chance that anyone else knows what they said to each other.
I would guess that if that becomes an issue, such behavior will rapidly be criminalized, and in China, harshly punished.

I've seen versions of several of these ruin people's lives very close to me. For example, I knew someone who played WOW to the detriment of his schooling, health, and social life. WOW is another product that is explicitly engineered to be addictive. The difference between then and now is cell phones and social media are consumed at a scale that affects almost everyone, to a degree that hasn't been seen before. It's worth studying whether this is something we should worry about or not.
I've been using gitpkg (https://github.com/ramasilveyra/gitpkg) lately; it works pretty well. Basically lets you use a git repo as a package repo, instead of npm.

Very little about how I use npm requires it to be centralized; I don't ever search npm looking for a package to install; I find a package I want and then look to install it.
> It will always cost providers more money to service users saturating their connections ...

I don't think it's an accident that so many people believe this myth. It sounds logical enough but it's completely false.

Fact #1 You have to replace technology because it fails over time.

Fact #2 The cost of networking technology is decreasing every year.

Fact #3. The performance of networking technology increasing every year.

Fact #4 The costs of running fiber to premises is a (mostly) one-time expense.

There's no reason that users couldn't have more bandwidth for less money every year. Technology is magical like this.

What opinion is expressed here? There's a vague implication of "this is unfounded" they cannot even be bothered to put in clear words, much less make a case for, while trying to make up for that by repetition.

> No but if you treat the "key exchange" process as a one time pad key, it doesn't matter that the actual ciphertext can be intercepted, since it's impossible to decrypt it.

Sure, I'm not saying you can't achieve information theoretic security. My point here is that discussion of quantum key exchange should use precision in terminology - integrity and confidentiality are meaningfully different. If the ciphertext from a quantum channel is extracted (in whatever way), it is not more secure than a ciphertext in which the keys were shared in person and promptly destroyed via Cold War-era means. You won't be aware of an adversary trying to break the encryption once they have it in their possession, and the ciphertext won't "break" if plied with an incorrect key (though it would be secure for other reasons). Rather, you'd know if the key exchange process is being broken, or if information was not transmitted correctly.

I've been running a site that started in 2000, never incorporated. Looked briefly at turning it into a non-profit a few years ago when I thought I was going to transfer it to new owners.
Not for income, but for learning and to scratch my own itch. Finally picked up a raspberry pi and a USB ANT+ reader to pair with my heart rate monitor chest strap. I've had an old 26" LCD TV in our home gym that I will use as the display for the pi. Goal is to create a simple workout timer that also tracks heart rate and logs everything to a local db. My goals out of this are:
- learn some python
- do some hardware hacking (it's been way too long since I wrote control codes for RS-232 controlled video equipment in the 90's)
- will probably do some image analysis down the road to do things like stride count on my treadmill, count reps in the squat rack - still mapping out the long term.

Next steps are to finish the plan for the mvp and then continue messing around. I also need to figure out the best input device for while in the gym and being quite sweaty; something wireless and somewhat rugged.

>a toilet roll dispenser at a public facility outside the Temple of Heaven in Beijing reportedly scans faces to keep people from stealing too much paper,

I have several questions:

1. Wait, am I stealing paper when I use a public restroom? Are those dispensers like the 'take a penny, leave a penny' tills?

2. Is there an acceptable amount of stealing which the facial recognition limits, or does it alert the management any time that paper is dispensed and leave the judgement to human beings?

3. There are literally cameras in the stalls?

4. How long is its memory? If it shuts me down, can I simply wait for someone else to go in before resuming my theft?

If i say that windsurfing "has a steep learning curve" i mean that to make progress, to move along the X, you must learn faster, move more quickly up the Y. It isnt that you do learn quickly, just that steady progress on one axis requires faster movement on the other. It's really three dimensional: experiance, knowledge, and the speed at which you want to move along those two.
I am disenhearted by the apparent pseudo-scientific thinking in the comments on this article, and how it'll "be better if you just go workout and eat better", which might work for some people, but not for everyone. If there was a scientific study about changing life habits to stop depression, I'd bet that it would have the same amount of effectiveness or even less than SSRIs. I myself have been "miraculously" cured from depression by the most ridiculed profession in modern medicine, psychiatry, and with "poison" that was supposed to ruin my life and make me kill myself. Basically, aripiprazole and fluoxetine helped me, and help me live life, work and be happy. There was nothing wrong with my life until one day I tried to kill myself, and I was very resistant to treatment because of years of people's anecdotes how psychiatrists were crazy, were "out to get them" and "chemically lobotomize" them. This is bullshit, and we all know it, during my stay in a hospital I have seen many cases of teenagers who were "beyond repair" get "fixed" with medications, and would you look at that, 3-4 years on, they haven't regressed (I kept in contact). Neither have I. It's dangerous to spread conspiracy theories to impressionable and vulnerable minds, and you should think twice before dismissing the whole modern science of psychiatry, just because you fell that hippie life and smoking pot is the way to fix anyone's life. I don't care about the downvotes, but had to get this off my chest.
I think the popular perception of a learning curve is difficulty vs time.
While there are obvious concerns about the effects of spending too much time playing video games, it doesn't seem like people are focusing much on the possible psychological impact of the kind of surveillance that modern technology affords parents.
