Well it kinda did, in early 2000's there would be one suicide bombing on average per week, after 2 fairly brutal military operations, and erecting a huge fence and checkpoints it pretty much stopped.

One can argue what was more effective the military operations that dismantled the infrastructure* or the fence but no one in their right mind in Israeli politics would wage on either.

It doesn't help them to stop the current run of violence with the knife attacks for sure, but many of the perpetrators in recent attacks actually were either Israeli residents (Palestinians with an ILR type permit) or even citizens so wall or no wall they could get to their targets in any case.

* Suicide bombings unlike many people think aren't a simple lone-wolf/small group type of operation, they are a very sophisticated and well funded operation.
The bombers are pre-selected usually by a close family member (uncle, older brother, cousin in most cases), they are groomed, then put into a program not unlike a one that the CIA would use to break a prisoner to get them to turn, they are brought to the brink programmed to disregard their own life.
The family of the bomber would usually be paid out up to 100,000$ coming from Gulf state patrons, in many cases they would be whisked away to Europe or other countries by NGO's that claimed that they were at risk for retaliation, one British NGO was "caught" processing paperwork for a family with the justification that under Israeli law their house will be demolished due to the attack prior to the attack actually taken place (this was discovered by NGO Watch IIRC several years after the event).
It would pay for medical costs if you didn't die.
The courier must arrive before the food is ready and wait for it. The food must be packed so that the least damage occurs. (eg. crispy needs to breathe, yet be kept warm) The courier must deliver it in under 10 minutes worst case, but within 5 minutes on average.

Like the constraint of the speed of light on networks, no amount of money can change this. Some food ages like VOIP traffic.

Pizza and Chinese delivery do well in the worst case. They reheat well. Look at what airlines serve.

To survive these new delivery services need to make a profit delivering food that is unprofitable for individual establishments to deliver themselves.
Common sense tells me that people should take some extra care with their homemade constructions before turning it into part of a business venture.

Maybe common sense isn't such a good guide, though.
Hmm.

While the ethics of using this technology / vector attack for advertising is hardly a difficult question, one thing does amuse me.

Nary a thought in this thread at what other little nasties this technology can be used for (I'd suggest looking into "mosquito" deterrents that can be used against teenagers).

Here’s some links – whilst you might not immediately realize their connection to this, I’m fairly sure others out there have.

The hippocampus, which receives a major cholinergic input from the medial septum/diagonal band3, is important in memory4,5 and exhibits network activity at 40 Hz during relevant behaviours6. Here we show that cholinergic activation is sufficient to induce 40-Hz network oscillations7 in the hippocampus in vitro. Oscillatory activity is generated spontaneously in the CA3 subfield and can persist for hours.
<a href="http://www.nature.com/nature/journal/v394/n6689/abs/394186a0... induction of network oscillations at 40 Hz in the hippocampus in vitro</a>

We used optogenetic tools to selectively stimulate VTA dopaminergic neuron action potential firing in freely behaving mammals. We found that phasic activation of these neurons was sufficient to drive behavioral conditioning and elicited dopamine transients with magnitudes not achieved by longer, lower-frequency spiking. These results demonstrate that phasic dopaminergic activity is sufficient to mediate mammalian behavioral conditioning.
<a href="http://www.sciencemag.org/content/324/5930/1080.short">Phasi... Firing in Dopaminergic Neurons Is Sufficient for Behavioral Conditioning</a>

Neurons were stimulated with a computer-generated steady barrage of random inputs, mimicking weak synaptic conductance transients (the “noise”), together with a larger but still subthreshold postsynaptic conductance, EPSG (the “signal”). DTX reduced the signal-to-noise ratio (SNR), defined as the ratio of probability to fire in response to the EPSG and the probability to fire spontaneously in response to noise.

By their nature accidents are unanticipated. As a general rule we do not proceed knowingly into certain doom. The proprietors of that BNB should surely be forgiven for making a terrible mistake, with no malice in their hearts. No one is born knowing how to run a hotel both safely and profitably (or even that they should be considering safety).

But that is precisely why we've placed barriers to entry for jobs that serve the public, to catch mistakes known to us collectively but perhaps not individually. You're right that it is your own responsibility to verify that a given course of action is safe. But it is also your responsibility not to market defective products, and to educate your users about risks associated with your product. The latter can and should be enforced by society.
Einstein was a genius, but he was also a jerk to his first wife and kids. His existence was certainly a big win for humanity I don't think of him as a hero, just a super smart guy that followed his passion. Being a good parent, or employee, friend is commendable but not heroic. The word heroic has become watered down to describe people that do commendable things.

Knowing you can be killed, disfigured, or severely injured within the next few minutes and still doing your job is heroic. Dan Carlin's hardcore history podcast described British soldiers in WW1 looking at their watches and knowing that in 5 minutes they would be going over the top into no man's land and would very likely be killed or injured. That hit me for some reason. Imagine taking your last look at the world around you and knowing that in two minutes you would probably be dead or wrenching around on the ground in complete agony, but you still go.
I've worked on the Cloud Foundry buildpacks team. What mitchellh describes for PHP (taking his example) is something that Cloud Foundry already does: take a codebase, apply heuristics to build and package it, then pass it off to a runtime. Heroku and OpenShift do it too.

The thing is that you're worried about snowflake deployment. You're still in the mindset that your app deserves special treatment; if it doesn't stage and launch using community-accepted best practices, then the platform is to blame.

I disagree. If your app needs zany configurations just to launch, I think that's a smell.

From time to time on buildpacks we would receive bug reports of the form "my app doesn't work". Usually, upon closer inspection, there was an easier fix: follow best practices.

The thing to remember about PaaSes like Cloud Foundry, Heroku, OpenShift and now Otto is that they are opinionated by design. The goal is not to provide an infinite supply of knobs and dials. We tried that with mod_perl, with PHP, with Java. It's a freaking nightmare made of sentient, glutinous mud that wants to eat your soul.

Our job as engineers is not to tinker. It's to create value for users and businesses. Clinging to the illusion of control is wasteful. When I fly I don't care about how the plane works; I just care that it's fast enough, safe enough and cheap enough.

The Depressing Effect of Bug Bounties
I have a core group of about 6 people one facebook I care about.

Unfortunately some of them are very narcissistic online and one baits with political bullshit. All are very pleasant to hang out with in real life. None do that kind of shit in real life.

The internet can bring out the worst in people.

I basically go on there once a week or once every two weeks to catch up on the "news" or if I get a message from someone (usually extended family, I have a lot) or an event invite. Unfortunately the narcissism is prominent because its "like" and "comment" bait. :| You could say these people aren't really my friends but, whatever, they like to use facebook to announce things (new job) because its easier than messaging everyone directly. Its also nice to get event invites from people you don't know very well who may otherwise not invite you because they don't know your phone number. Those are opportunities to make new friends. The barrier to getting to know someone better is low. That's nice.

Over the years we've spread out geographically so I can't see them face to face very often but I do as much as I can. (every few months)

Its easy to say only engage people who "enrich your life" in all aspects of it and are 100% perfect but humans are not perfect and facebook caters to a deep human need for attention/group acceptance. I also believe that surrounding yourself with people exactly like you in every way isn't very healthy. There's a lot of people that I don't like at all and I avoid if possible but for the people I do like I tolerate the differences we may have.

I don't have a use for pages or whatever they call them or anything like that.

I could get rid of my facebook but its alright for the amount I use but I couldn't stand being on that shit every day.
Are you still a hero if you die invading a country for its resources? What if you die because someone asked you to walk into gunfire for no reason and you did? Is it the death that makes the hero, or the defending others? If the latter, why does the hero have to die?
If you take an African witch doctor with hours of trance dancing and plenty of chicken blood, it is probably all placebo.

Both for someone of the same tribe, who has been brought up in the same belief system, having been taught to look at the doctors in awe, a dramatic treatment by a witch doctor probably is tremendously powerful.

My guess is that it will be much more powerful than mindfulness meditation. (And this is regardless of what is attempted treated - (self-reported) pain from a hot prick or the common cold.)

In others words; the self-healing/self-suggesting effects that we call placebo has something to do with belief; and probably belief in a broad sense, whether the subject believes, whether the doctor believes and whether the surroundings in general believes.

In a way things like mindfulness meditation is part of the "folk-religion" of the modern man. Read any women's magazine / self-help book and it will tell you that mindfulness, positive thinking, biodynamic food and exercise has strong effects on your physical, psychological, sociological, even financial well-being.

Most of this is not science. But some science supports of the claims.

I think that a good question for science to ask is "has these things always been true?" Are they deep physiological facts or are they changing over time, over culture?

The study summary mentions that the effect of the cream was 10%. The cream I suppose was made to look like traditional western medicine applied by some kind of nurse or doctor.

Suppose this experiment had been done in the 50es where skeptism towards Western medicine was much lower and a doctor's authority was much stronger. Would the effect be same? My guess is it would be stronger.

Likewise maybe saying a prayer worked better for the believing Christian Western man of 200 years ago than the modern "scientific" techniques of positive thinking, mindfulness etc. would have.

How would you crack this in a scientific experiment?

It is probably very hard because the experimenter's beliefs also comes into play. Double-blind is one way to go about this but for what is examined here it is probably not possible to do effectively. And secondly the subjects would be affected by what they believe works and already know about.

Maybe a simple place to start would be to ask the subject (and the experimentor) if they believe the treatment would work? And maybe survey general attitudes towards traditional medicine, alternative medicine, meditation, health etc.
I don't think the parent is arguing that the family in the story didn't deserve a settlement for his death (at least under settled US law). His point is that the man who used the swing is dead. If your ultimate goal is to stay alive, then the burden of care is on YOU. If your goal is to garner a sweet multi-million payday for your family, then swing on!!
A bit off topic, but AirBnB's big conference is going on right now. In Paris [1]. It's a complete coincidence, but probably means the issue we're talking about here is on their far back burner as they try to ensure the safe return of everyone there.

According to the FBI (https://leb.fbi.gov/2014/january/active-shooter-events-from-...):

[In] 33 percent (17) of the cases that ended before the police arrived, the potential victims at the scene stopped the shooter themselves. Most commonly they physically subdued the attacker (14 cases), but 3 cases involved people at the scene shooting the perpetrator to end the attack.

So it appears that even the FBI says there were 3 over a span of 12 years that were foiled by armed citizens. And that fully one third of them were stopped by citizens without guns.

I would assume that if everybody were armed then, that more than 33 percent would be foiled by armed citizens.

That is of course, if you accept the Federal Bureau of Investigation to be a credible source
Blaming the violence of the Middle East on Israel is naive.
A similar problem happens on iOS CarPlay.

If you're getting navigation directions in Maps, and then go back to the home screen (say, to play music), there's a temporary notification dropdown that appears from Maps with your next turn info. The problem is that the dropdown covers the top row of app icons, so if through muscle memory you (as I do) hit home and then hit Music, you hit the notification instead of Music and end right back in Maps. It's infuriating.

This problem makes me question if anyone from Apple's CarPlay team has actually used their own product in a real setting.

Not to disagree with your point about Bayesian reasoning but would you care to cite some source for your assertion about the relative dangers of white-supremacy groups and their ilk versus Islamic terror groups? 9/11 alone killed 2996 people [1] including hijackers and there's little question Al Qaeda/ISIS adherents would have killed many more if they could have. It was certainly not for lack of trying.

The OPEC was able to put itself in that position due to limited worldwide supply. That has changed. Its no longer rational nor convenient for them be a supplier of the spare demand in an environment where doing so would keep prices high and encourage investment in oil production capacity outside OPEC, thus further eroding spare demand and market share.
On Cloud Foundry we've found that we get buy-in from both operators and developers.

Operators heave a sigh of relief: "Finally, I don't have to clean up after devs! They can't break the platform for everyone else! I don't get 3AM phonecalls to fix someone else's mess!"

Developers heave a sigh of relief: "Finally, I can just deploy without dealing with suspicious operators! If it breaks I don't get berated by an operator who got a 3AM phonecall!"

I imagine OpenShift and Heroku guys can tell the same stories.

I work for Pivotal Labs, so I get to see projects with PaaSes and projects without PaaSes in a variety of companies, on a variety of platforms, with a variety of goals. But one thing remains constant: PaaS-deployed projects are easier.

In a PaaS-deployment project, you set up your credentials, set up CI/CD, then you just get on with doing the thing that matters: building a product.

In non-PaaS projects, you spend eye-blistering amounts of time and money trying to just deploy the damn software. The whole feedback loop turns into a tangled pile of spaghetti behind somebody's bespoke deployment process. Backpressure causes enormous shear stresses throughout the project because development is iterating quickly but there's no way to, you know, see if the users like it or to know if it actually works in the real environment.

It always boggles my mind that folk are happier to squander amazing amounts of engineering time and salary dollars instead of just renting or installing a PaaS.
I completely forgot about the response to aerial photography when it first came out. I remember having some concerns about the privacy implications and feeling 'exposed' on the internet that anyone could see my home. Funny how much my mindset has changed.
Except if you look at the screenshots, there's no information.

That's the key thing with google maps or google earth, it's the information around what you're looking at that is important, and google understood that.
I believe is just a question of mentality. Programers, being traditionally more closely related with the new technologies and the internet, soon saw open source projects as a way to improve their skills and promote themselves at the same time.

Artists, lagging behind in new technologies, still didn't embrace these projects as means to self promotion. But I believe this will greatly improve with time.
Have any idea how many of us are even better trained ex-military?

In the US, about 13.4% of men are veterans. And 1.4% of women are veterans. So if you're in a theater with a hundred men and a hundred women -- fifteen of those people are competent in the responsible use if firearms AND have proven themselves willing to put their lives on the line for their countrymen.

I'd put money on an overweight, half-blind, ARMED, 60 year old US Marine up against 5 religious zealots with AK-47s any day of the week.

Hell, even those Air Force guys probably know what they're doing :-)
This is completely tangential to the discussion of this thread, but so much of google search is forecasting based on user's search history these days it's hard to tell if it's just biased towards HN because we all visit it.
While I agree that everyone has that potential in theory, it is much more likely for radicalization to occur among certain groups, third-generation muslim immigrants in particular. And perhaps in a broader sense targeting people in particular socio-economic groups might also be useful (jobless, young, low education,etc.).

The way I see it, targeted surveillance of these at-risk groups should be possible, and specifically in relation to terrorism or extremism in general it might even be effective. There are volumes of studies on how radicalization occurs, or how cults work, and what problems are caused by jobless young men disconnected from society around them (both by upbringing and through various forms of racism/classism, hidden or otherwise). The process is not exactly mysterious.

That said, I get the impression that there's a huge gap between what researchers know about these processes, and how this is used by police, 'neighborhood watchers', and schools, and possibly even intelligence agencies.

I'll also add that regardless of how effective targeted surveillance might be, on a 'gut' level I feel uncomfortable with this scenario and would not be in favor of it. I can't quite articulate why at this point, but personally I'd still prefer not significantly changing our way of life over the, so far, infrequent terrorist attacks. Perhaps the best answer is to simply not let it phase us and continue with life. Most other solutions feel like (partly) playing into the hands of terrorists. But I don't think that's a realistic option, sadly, and perhaps it's easy for me to say these things without having felt the effects of such terrorist attacks personally.
People who share a certain ideology aren't an "ethnic" group. We do exactly the same with nazis.

Whether those measures are effective or desirable is up for debate, but the constant attempt to shut down that debate by playing the ethnic/race card is extremely counterproductive.

No, that is not a solution. You are responding with fear to the fact that the world is a dangerous place. Fear is not a place from which to make decisions. Terrorist attacks are barely worth replying to, they kill very few people and simply don't matter; they are something for police to deal with, no laws need changed, no big actions need taken, ignore them, they are statistical noise. Cars and lightening are far more dangerous.
Actually, it kind of did. Israel does probably the best job of counterterrorism in the world when you consider the constant threats they face.
