Ask HN: Why not use Graph DBs as a general purpose DB?
Am investigating some db technologies for an application I'm working on and just came across Graph DBs (note I'm not a db guy). Just playing around a bit with neo4j's online REPL felt a little more natural to model out data. However, as I dig into it, people seem to take the stance of GDB being particularly well suited for certain applications but stick with Relational where possible. Is this mentality more about Relational being much more widely adopted in society today (and thus more tested, optimized, understood, etc.) as opposed to some deficiency in modelling problems with graphs (I'm inclined to make a comparison between functional language vs object oriented vs procedural programming languages where thinking in Graphs these days causes a bit of a mental shift and therefore dissuaded b/c it "feels" different -- much like going from C (procedural) to C++ (oo) and now C++ (oo) to F# (functional) )

For example, if we just take a simple case: Modelling out a Restaurant Menu that serves Breakfast, Brunch (on Weekends), Lunch, Dinner, Desserts, Drinks, I can see both GDB and Relational being able to solve the problem but why would I necessarily choose Relational over GDB (or vice/versa)?
Use of pressure to control the behaviour of the tool there has:

A) immediate graduated feedback (perhaps a learning point for pressure sensitive interfaces here?)

B) is something that you have to learn to do well (an awful lot of people never do - most people aren't artists.)
Had the following thought just to entertain myself, I don't expect it to have any utility in practice, but here goes:

Take a small interval around your smooth function that includes the point where you want to compute the derivative. Joint the right and left ends by just reflecting itself, so that you have a differentiable periodic function. Now sample that at a suitable rate, take its FFT, derive the FFT of the derivative by multiplying it with 2\pi I. Take the inverse FFT and evaluate it at the point of interest. May be useful if you want to compute the derivative at many points, but seems wasteful otherwise.

One of course has to dot the i's and cross the t's (of aliasing effects, Nyquist limits etc). Perhaps some other fast integral transform would work even better. I will be surprised if there isn't an old industry around it.
Data point: private daycare for 1-3 year olds (4:1 ratio) is about €1700/month in Germany, but in my town it gets subsidized by around €8-900/month. Some counties subsidize down to 0 cost if they want to attract families; publicly run daycares are around €450 for daycare and €220 for kindergarten, but they have stricter closing jours (our private one is open 8-6) and more days off per year (up to 6 weeks).
> other takeaway is this: do not go to the bathroom. Do not leave. Do not take your eyes off the object of your interest for one second, or she might leave and you'll never see her again.

If the object of your interest wants to leave, I'm not sure imposing yourself on it is the best way to keep it around.

"Children who rebel may be threatened with being sent to stay with family in China, and they know from relations there that teenagers in America, even Asian ones, get off relatively lightly compared with those in China."

This seems quite naive. We all have been children and something like this seems unlikely to work (at least my personal opinion).
Of course it matters. If it's real, it's a strange, perhaps touching story. If it's made-up, it's a trite and rather artless attempt to yank at your heartstrings. Being coy about whether something is a true account, fictionalized or outright fiction is a cheap way to avoid criticism of both one's reportage and art.

I didn't say they have to keep their computer unlocked, some of them did lock, but I did not enforce a locking policy because I don't think it was necessary in the context. And if I did have to enforce screen locking in other places, it would be out of question to use any passive aggressive behavior or public shaming towards a teammate, if you need trust from your employees, you treat them well. My first reflex would be to look at technology, because locking the computer is a stupid and consistent task and technology is for stupid consistent things.

I think people are too focused on working for military and paranoïa, we need a range of behaviors, from the paranoid to the welcoming, that guy watching your screen could start an interesting discussion about your project, and give you the contact to the right person to help you. You don't want that in a military context, you highly desire it when you're building a vegan pet food marketplace for hipsters.

Not everyone needs to develop like in Aerospace, not everyone needs to develop like in video games, not everyone needs de behave like a NSA agent, and not everyone needs to behave like a farmer's market salesman, we need a range of behaviors.

And whatever the policy, you never, ever, let co-workers be dicks to each others, no "pranks", no public shaming, no sending a prank email from each other's computer. If security is really an big issue, then not locking a computer is a strike, it goes between the boss, the offender and HR, not a matter of joke.

Its a good idea. The inter frame compression is the point which would be nice to have.
Imagine how much a Interlisp-D, Smalltalk, Mesa/Cedar workstation would have cost in the 70's versus a plain PDP-11.

Eh, if they'd put Altos in serial production instead of small batches at a time adding up to 2,000 units it wouldn't have been vastly more expensive. There was nothing both exotic and wildly expensive about them compared to contemporary PDP-11s + a graphics console. The extras were a mouse, chord keyboard, network adapter, and more memory per person than normal for a PDP-11.
Yes that is a big issue as well as new keyboards (like the new Google Pixel keyboard) coming on the market lacking keys people who code and/or use shortcut have gotten used to.

I believe VW have promised to replace everyones entire engines. I'm stupefied over how much this will cost, i've seen numbers around to 100B mark. Their market cap is somewhere near half of that. Presumably they think it's better than the brand damage otherwise. I think it's fair to assume they'll go bankrupt over this.
Actually there are parts of you that were parts of you in your twenties. Some of the brain cells, some of your heart cells, and if you are a woman, your eggs.

Using Pyenv with Mac OS X El Capitan
I've not time to read a book and reply to this comment in a timely manner, however: I'd note that lack of sleep in itself can cause some pretty freaky stuff to happen to people's minds in itself. If that is the experience I'm reading about - with an overtone of LSD - I cannot hold that representative of a bad trip.

Occsionally,people do have bad trips, however, there is truth in that. For me, that goes back to making informed decisions. Legal sales from trained folks, with stableized ingredients and dosages helps with such things. Yes, a few people are gonna be stupid, but that basically happens with everything.
Good. Maybe capitalism will be allowed to work, the dollar will weaken, and the US will stop running half trillion dollar trade deficits every year. Trade deficit = public debt + private debt.

http://www.frbsf.org/education/publications/doctor-econ/2007...

The strong dollar and the unregulated medical sector are virtually the only problems with the US economy.

The high US dollar is sustainable as long as the American public are willing to collectively take on a half-trillion dollars worth of debt every year.
Four Things You Didn't Know Your iPhone Could Do
This isn't true for me. I'm more likely to get a good night sleep and wake up well-rested, without a headache ready to go to work after a night of smoking. I'm more likely to call off work if I am feeling sick from drinking the night before: In fact, I'm more likely to simply not go out after work to drink. I can smoke some and do my household stuff in the evening, walk to a coffee shop afterwards and talk with folks, draw, read, etc, most of which is impossible when drinking. I'm gonna guess absenteeism is higher among chronic alcohol users than it is among chronic pot users, but I don't have the citation to back it up.

What are the security implications?
What's interesting to me too, is that they are also neglected in the discussion about diversity in tech. They are the most over represented minority in tech, and instead of looking into why, and how it happens, can we find a leverage for other minorities, what open them doors but not blacks and hispanics, they are just overlooked.

Complaining people just overlook them as: "it's a bunch of white males", but Asians (and Indians I think) might be a key for change this situation.
I think we're just scratching the surface when it comes to the types of health data we can retrieve. There is a lot of power in bringing together data sets from the sensors/apps (more of a continuous feed of wellness data) and correlating that with discrete medical data models.

The startup I work at is stitching together all of this data to gain a better profile or health state of a person, and it's pretty amazing some of the early insights we've been able to uncover.
Criticism is positive if it's argumented and there's an actual reflexion; you can potentially improve something based on the criticism, so you should always have an eye on it. Anything else is just garbage and shouldn't be taken as worthy.

Basically, anything that is above level 4 of this (http://www.paulgraham.com/disagree.html) is worth listening for.
That's the thing - most people that regularly smoke blend seamlessly into society. It isn't that we are talking smoking joints as cigarettes. What most people refer to as smoking is more equivelent to binge drinking rather than a glass of wine with lunch and/or dinner.

Sure, but you don't have to hit that right pressure point. No matter how hard you press, when you first engage it you will always only be at the first preview step. Then you can press harder still, sure, but you cannot just skip a step.

It's very well thought out. This is all about the software implementation. Pressure sensitive screens by themselves are boring tech.
Unfortunately, json.api is such a terrible idea it could have been invented by IBM. I doubt it'll see much adoption, and so far has had almost no industry interest. The problem is that it leads to very weird code. When HATEOS is done right, there is no need for such a thing. Also, is really misnamed - it's not actually json, but a little part (the last interesting part) of hateoas that it's actually supporting. Good luck with your project.
Tales of coding from a beginner
Building an Alto then required lots of money, you can prototype fairly complicated things now on a cheap FPGA.
GUI interaction is more intuitive and thus easier to learn (children learning tablet use without previous instruction for instance) so yes everyone uses their mouse as they do not know better. Most experienced users use either a mix or only keyboard. For things like coding or writing books and papers (and many other uses; I believe it to be the case for most common uses of Photoshop as well); I dare you any day of tĥe week in a contest where you use only GUI without keyboard shortcuts and me on only keyboard for coding and see who is more productive. I think we can calculate from what mouse movements you need it is probably not physically possible for you to win that. Not that that says all as for the general population GUIs feel more productive compared to the effort you need to actually learn to beat that 'natural' productivity they got from nature.

I have tried Mendeley, but despite its odd (Swig-based) interface, I prefer JabRef (http://jabref.sourceforge.net/). It is open-source, and it keeps its database of references in plain BibTeX format: therefore, it is super-easy to edit it by hand, when necessary. It does not offer facilities for searching/discovering new papers, but IMO it is perfect to manage a database of citations.
It's text. Would have used asciinema as a base and streamed that in.
I've gotta say, whether taken literally or metaphorically this sounds a little creepy. On the literal level, clinging to someone constantly so they can't get away is likely to come across as somewhere between desperate and terrifying. And metaphorically, this level of focus can be fantastic in the short term, but taken too far it's a recipe for burnout and a hollow, fragile life.

I'm carl, a British freelance Designer & front-end developer.
I focus mainly on the design of web & mobile applications, interaction design & prototyping. I wireframe, AB test, create incredibly usable UI and back up my decisions with research.
I'm as comfortable in Sketch & Photoshop as I am with front-end code. Extensive prototyping experience means that I'm good at writing clean, modular CSS and integrating into development teams to release the work.

Yeah, Alan Kay says things to that effect, too. Another way to look at it is, assigning all the credit for those "trillions in value" to Xerox PARC (my oh my, creating so much value and capturing so little? how did that happen?) is a warped way to look at the history of computing and thus is the perfect example of the problem that makes you "embarrassed to work in this industry."

As to Niels Bohr... I think the transistor or the concept of decidability are more like what physicists do/achieve than OO or WIMP interfaces. One can disagree with that but one can also agree with that, I think, even if their age is above 20, their memory spans whole years etc. etc.
I have seen (most of) this methodology elsewhere, but you've clearly pushed objective-creative thinking to the limit there! also this has been one of the most vivid and crystal clear depiction of its class.
I was also lost at that part, although for a different reason. The function f was assumed to be from R to R, so it does not make formal sense to plug in f(x+ih).

I guess the author has the unstated assumption that f is the restriction to R of a function on C.
You have to fit it into the narrative that's being peddled.
Communists have never cared much for truth. They love using jews as shield, but the left is becoming as anti-semitic as national socialists. Especially in this day and age as BDS.
Apple blankets the world with ads. Apple has recognition. The iPhone is relatively focused in its additions and it's not like they added a million different things, all of which they have to tell you about. There is only one iPhone and not millions different models with different features.

Unlike many Android device manufacturers (except maybe Samsung if they were to focus for once and not be so overwhelmingly complex in all the stuff they put into their phones) Apple is in a unique position to actually teach people about this through marketing. And they will. They will teach people about it, devs will be on board real quick and it will just become a natural interaction. That's my prediction.
I seriously doubt Germany would let VW go bankrupt, the government owns twenty percent of the company and they are too big too fail.

Social norms are powerful things. Some people did a study at the Petrified Forrest National Park on how to prevent people from stealing pieces of fossilized wood. When they put "Many past visitors have removed the petrified wood from the park, changing the state of the Petrified Forest’" on signs the amount of theft was much larger than anything else they tried[1]. So if you're running a public awareness campaign emphasizing how many people break the rules is just about the worst thing you can do. The message DARE seemed to be giving me when I was a kid was that drug use was normal.

Well, it's regular mean reversion. China's treasuries and others will eventually grow as reserve instruments. Also, the primacy of high US salaries / income relative to the rest of the world also looks unsustainable.
I guess it is because on the Macbook, the "Taptic Engine" (i.e. vibration motor) is directly under the glass of the trackpad, so it's actually gently moving the glass, which feels a bit like you've pressed it. On the iPhone, it is the whole phone that is vibrating rather than just glass, so it feels less like you are directly interacting with the glass, and rather that the phone is responding to your touch. I have to admit, I was hoping it would feel more like the Macbook Force Touch too, but I guess it's just not possible to build it so the vibration directly affects only the glass with the current design.
Actually, not every physicist knows what Niels Bohr did. I know a very smart and hardworking physicist who did some complicated math on details of particular renormalization procedure in quantum field theory but could not explain how Bohr's model of hydrogen works.

As to the Computer Science detriment, aren't you confusing computer science with a programming job? Do you really mean that the science is done by 21 year old people with no long term memory? I find that hard to believe.
I won't even comment on Therapy. I noticed you assumed, and rightly so, the uproar would be over psychiatic drugs? I don't have a problem with Therapy. Is hard to study, and at worst it doesn't seem to have any bad side side effects--besides on the wallet?

We do get are feathers ruffled when Psychiartic drugs(mainly tricyclic, and hetricyclic antidepressants) are brought up.

Why, because so many of us took them.

I took them. My friends took them. I even encouraged a ex-girlfriend to take them. In my case they never worked, but I believed the literature, and thought I was just unlucky. I spent thousands on different drugs for depression and anxiety. I can't put a price on the side effects, and disillusionment.

I imagine a lot of people are still on them. They were billed as the Wonder drugs. They were very expensive. Patients and Doctors were equally lied to by drug companies. They caused a lot of unnessary pain, and suffering. Too many people are still on them. I sometimes wonder if there's a correlation between some of these drugs and violence? I know if I was a prescriber, I don't think I would prescribe a heterocyclic Drug(Proxax, Zoloft, etc.). I just don't believe they work, but the industry is trying so hard to still justify their use--in selected patients--you know the "sickest patients seem to get a bit better--sometimes--in some situations?"

If the history, and study of Erythromycin is in any way like the history, and study of Prozax; I will never take another antibiotic again.

It's not that we hate all Psychiatric drugs, but some of them, especially the Happy Pills; were studied terribly, some even fraudently, and a lot of psychiatric patients are still very leary of a lot of these drugs; And so are the drug companies. I don't see any dancing pills in commercials anymore like I did in the 90's and 2000's? I just see ads by Lawyers. I don't see hubristic Psychiatrists advertising as "Chemical Imbalance Specilists" anymore. Psychiatry was hit hard by the deceitfulness of these drug comapnies. The profession just doesn't have the glamor factor anymore. Patients don't look at them the same way. I actually feel sorry for the honest ones, and the ones who keep their office visit prices reasonable. I couldn't imagine doing my residency in Psychiatry after graduation from med school these days. My fear is the wrong students will be admitted to Psychiatric residencies--students who weren't the best and brightest in medical school?

So yes, there's usually an uproar when articles like this hit. I don't care if a particular drug is slightly better than Placebo; it's when they are so close to placebo, or not even close to Placebo when you include all the discarded/badly done studies, and all the metadata that boils my brain.

They history of Proxaz makes makes a good read. Personally, I can't even read it anymore; it literally makes my head hurt.

At least US bonds being priced in USD does reflect the risk and demand associated with them.

What I wonder is, how is inflation being calculated in terms of the CPI, which is essentially prices in dollars? After all, what exactly is being measured by this? If dollars the very currency which is being printed, how does measuring prices account for how much M0 money there is?
