This has happened, to some extent:

At the Instituto Oncologico Nacional in Panama, some doctors discovered that they could fudge things to circumvent some limitations in the software that calculated shielding block geometry for radiotherapy patients.

In essence, the system could only handle 4 blocks, but it was possible (and sometimes correct) to add more than one block as a single shape. If this happened in the wrong order, however, it would screw up.

The staff in charge were brought up on civil (and possibly criminal) negligence charges, from what I recall.

Edit: Yep, according to http://www.scielosp.org/scielo.php?pid=S1020-498920060008000...

[search for "Legal actions" heading]

"On 18 November 2004 it was announced that one of the physicists was acquitted, but the other two were found guilty, sentenced to four years in prison, and barred from practicing their profession for seven years (45). They have initiated an appeal process, but they are very worried, given the precedent established by the Costa Rica case.

The [...] Costa Rican physicist [...] was accused of negligence in 30 homicides and 59 radiation injuries. He was also accused of falsifying documents and of using false documents. On 30 July 2001 he was absolved of the latter two charges, but he was found guilty of 14 homicides and 50 radiation injuries. He was sentenced to six years in prison and barred from practicing his profession for five years."

>Chaos doesn't mean you have to throw your hands up and give up on making any long term predictions at all about a system.

But we can't tell what the weather will be in 45 days in New York.

One of the attributes of chaotic systems is their self-similarity. The behavior on one level is similar to the behavior on another - in this case weather is similar to climate. We can make predictions about the weather in the next few days, just as we can with climate, but in the next few months or years (or centuries or millenia for climate) is another story. The tiny pertrubations in the system which we do not model (the butterflies) end up throwing our predictions off in the long run.
> Just because the physical reality is given and closer to us, we can't rule out other forms of existence.

We can to the same extent I can rule out the existence of one million dollars in my bank account right now.

> And say that, somehow, a percentage of humans had some sort of experience of the supernatural.

If this is distinguishable from schizophrenia, they should be studied in earnest and learned from.

> But it can not be objectively verified.

Yes, it can.

> Taking the exigence of objective, material verification of experiments in Physics to a field of subjective, psychological/spiritual experiences, seems to me to be a mistake.

No. All reality is founded on the same laws. If there was something special about consciousness, it would have repercussions on every other facet of existence, and it would need to be studied on those terms.
This isn't about FDA regulations[1] or tort law[2]. It's about the American medical system being a corrupt racket.

1. The FDA will approve nearly anything. For example, very flexible user-managed insulin pumps.

2. A jury of retards will convict if the plaintiff is sufficiently pathetic. Assuming you have reasonably good intentions and reasonably clear documentation, tort liability is just a roll of the dice.
While I don't necessarily disagree, that's like saying hackers ruin everything. What do lawyers (hackers) do but try to find weaknesses in the current law (program) and exploit them? We haven't figured out how to make perfectly secure systems that are still usable, so why do we expect our laws to be any more robust?
Exactly. Having a website load slowly is nothing compared to the insides of an Iranian torture cell. For more and more people, this is not a false dichotomy. Tor's speed is not the result of poor engineering; instead it follows from the properties a high-anonymity, low-latency network necessarily has. As users, before we complain about speed, we need to keep this in mind and consider whether we require such protection.
Ugh ... Who else uses multiple sign on for Google Accounts?

> Making the positive statement that the 'Universe is uncreated', is just as intellectually justified as saying 'The Universe is created'.

No, because the statement "The Universe is created" demands that the person stating it demonstrate the existence of the creator in a way that rules out the likelihood of that creator not existing.
Only full face masks do. The nasal ones don't.

Technically you could breath through your mouth if there was a problem, but some people have issues keeping themself from breathing through their mouth, so they use a chip strap to prevent it. And then this hazard comes into play.

And you entirely missed my point. The masks are safe because someone thought of the hazard and designed against it. If you are making things homebrew you better make sure you are aware of all the hazards.
Belief vs Reality
A better summary is needed. I quit out when the beginning ad-speak didn't wrap up in 2 minutes.
> As for the certainty, no one so far has created a test, not even theoretically, to discern between a created and an uncreated thing.

It's simple: Demonstrate the existence of the creator.

> As I said, I have an opinion/belief.

Why?

If you don't mind me asking, what's your competitive strategy? It's possible to create something valuable for yourself, and then it turns out other people value it too; but that can attract competitors. Though serendipity can often creates value, it serendipty rarely seems to protect it - it's common that the person who sows doesn't reap. Competitive advantage seems to need a deliberate strategy (though I'm more comfortable creating than defending). Do you find this too?

Try a different mask. There are a huge number of types, and different people like different ones.

Nasal, dental, full face, nasal prong, nasal pillow. And the straps attach in many different ways as well.
In principle you are correct. To an advertiser it's much more significant what it is you do when you're on the internet than who you do it with. So in that sense Google is much more valuable than Facebook.

The problem is humans are social creatures. So if all there is is Google, humans will do stuff on the internet and Google will know about it, but the social aspects of life remain offline and therefore inaccessible to advertisers. Facebook has managed to get people to spend a much larger percentage of their time online by moving part of their social lives there and they're gambling that a significant portion of that time people will do things that advertisers will be interested to know about.

Personally, I doubt this gamble will have the payoff they're apparently expecting. The primary focus during social interaction seems to be on, well, social interaction. Consumption only plays a very small role (though I'm sure Bacardi would like to pop up ads while you're chatting with your buddies on Facebook). Facebook basically catches people only when they're in the mood for fun and relaxation, whereas Google captures people right when they're in the mood for consumption and for spending money and to an advertiser that is much, much more valuable.

Blue Ocean Strategy

http://en.wikipedia.org/wiki/Blue_Ocean_Strategy

Edit for the tl;dr crowd:

The blue ocean strategy is about creating your own market/niche/space in an new or uncontested area (blue ocean) vs. competing directly with established players in an existing market (red ocean).

The metaphor is the red ocean is full of blood from the sharks fighting over the same profits/market share while the blue ocean is open water full of opportunity.

Ah yes, the days of computer labs in high school and figuring out that outlook lets you copy and paste emails in the Outbox. Just get a big enough collection and keep copying and pasting. Easy recipe for getting hundreds - thousands of emails.
You're making this way more complicated than it needs to be. It's not an alerting system, it's a knob, like a thermostat. I turn the knob where I want it, the system follows the "run until this limit is hit" instruction. If I want to change my mind later, even after the limit is hit and the system shuts down, I can make that decision at that time. I don't want the system or anybody else to make it for me.

As for the "purchase approval" nonsense -- if the knob isn't right for your company, then don't use it, but there are a huge number of companies where the guy turning the knob is the one and only person with any say over money being spent at all.

Lucid dreaming is possible, but not everyone can do it. Of the times I have personally done it, it has been awesome! I achieved it with the reality check method, but I think a device would make it a lot easier..

There is an interesting new iOs app called Dream:on (it's free too) that uses the accelerometer to determine when you are in likely in a REM state, and then it plays audio cues to help get you into a lucid state, instead of flashing lights like the remee.

I haven't had the bed to myself to try it out yet - my wife is a very light sleeper - but in theory both of these devices could work, but don't expect it to happen immediately or every night.. and you may need to incorporate a reality check method too, the device cue would just make it easier to do.

As is often the case, the people who perform risk analysis and prepare recommendations are different from people who actually implement & enforce compliance [management].

Agree that there is not much one can do, since the 'in'compliance badge is a one-way ticket.

There is a difference between following the rules at own discretion and actually knowing & understanding the rules, accurately assessing the risk for each specific business case and making the right decision.

Usually typical management types do not take time or are willing to learn the rules. Hence, in the absense of knowledge they prefer to be on a safe side, i.e. err to hitting every moving object.
Ask HN: Would you pay for Github Project Management and Collaboration?
I'm building an app for simplify project management on Github: IRC and Campfire style chat, drag n drop file sharing, Pivotal tracker style issue management (all real-time), card (issue) walls, full keyboard control etc.

Basically an app that will let programmers collaborate and manage a github project.

I'm thinking of a Metro-style design, but more importantly, well thought out design - since I'm independent I can spend a lot more time and effort making the app clean, fast and efficient.

The starting point (right now it's just a proof concept and an experiment with the APIs) is up and running. Try https://airport-r7.appspot.com/madrobby/zepto or https://airport-r7.appspot.com/wycats

Free for public repos and for private repos you pay exactly what you're already paying at Github and you get an equivalent plan.

If you can imagine where this is going, would you pay for it?
And to nit-pick even further: These images resemble the graphics of the Amiga and Atari home systems, which were 16-bit systems. To do this on a PC you would need XGA graphics (VGA couldn't do 640x480x256) which arrived at the PC around the time of the 386 processor, which was 32-bit. I think you could probably attach a XGA card to a 286 PC, but that was still 16-bit. I don't think anyone ever paired a XGA card with an 8088 PC, which actually was an 8-bit system.

So, this isn't even 8-bit art, it's more likely 32-bit art. :-)
For those of you on the fence about watching this one: how interested are you in "Bootstrapped company produces a software product which is used in the Situation Room at the White House?"

1) Calling a customer back while eating Cheerios and getting the response "Situation Room. Dan speaking."

2) Raising prices by 100x and how it made the business/customers happier. (p.s. I personally think Stormpulse is still underpriced. The Situation Room uses it. NASA uses it. Charge them DoD prices for a hammer, at least. ;) )

3) How he played news media outlets against each other, using their herd mentality, to get widespread distribution (but not revenue at the time).

4) Practical experience with setting up charging credit cards. How that evolved into the current paywall. What changes helped conversion.

5) How it was funded with a combination of bootstrapping by working a day job, getting friends&family money, a not too successful fundraising campaign (and the low point there), etc.
I don't see the connection. Is Go even bootstrapped?
Cool. A Brainfuck-ish langauge, but more powerful.

Printf tells you "this function entered, then that function" while the program is running. Unit tests are trendy, but how do you know what to unit test before you even know the code paths? Do you even care about individual functions at that level? Printf may be dirty, but in the initial stages it's better even than a debugger with breakpoints.

Steampunk Sherlock Holmes: An Ambitious Interactive Book for the iPad
The most valuable hack I've discovered and used when dealing with the health system (and bear in mind this is in the UK, where the main problem is not cost, but time) is to be great friends with a GP. I always discuss health issues with him before going to the doc, so there are no surprises afterwards, and I know exactly what to say to expedite the process.

It turns out that there are various magic phrases you can use to speed up the outcome, guarantee a referral, etc. If you're friends with a doctor, they'll tell you those phrases.

It probably won't help with all the waste in the process, though. And it definitely won't help with closed hardware.

Very easy when the cost is so tightly coupled with the resource use...
Agree. The question I ask myself is what truth do we get from such survey ? It depends on the people who are responding to the survey. This is just probing. What about product user feedback and product optimization based on the feedback ?

As Ford said, if he asked people what they wanted, the answer would have been faster horses. So the question asked is of course important, and as much as the surveyed people. This may work only for particular ideas. And finaly only the execution will make the difference.

I guess this is the old question of Do you want to be the boss or do you want to be rich?
Very simply, the medical system can extract as much money from the patient as they want. The worse the illness, the more the patient will pay. Because the alternative is death. Health care is not a matter of supply and demand, it is a matter of life and death. Patients will give you the shirt off their back to avoid death. It's just not fair.

That is why strong government regulation for health care is a good idea.

These things run far more smoothly in countries with a public health care system. There, doctors typically get a fixed amount of money for each kind of illness. Hence, their incentive is to diagnose an illness as swiftly as possible and get the patients out the door. This has its own set of downsides, but at least the patient gets help rather more quickly and with less hassle.
Hmm, it's more like any ionizing particle (charged) creates pairs electron/hole, many of them, so that the charge distribution in the pn junctions are altered. Sometimes gamma photons generate Compton electrons in the material that act as delta rays, to the same effect. Heavy particles can alter the crystal structure, inducing defects that may change its properties. Magnetic storage devices don't have polarised junctions and could withstand all this if they didn't include solid state electronics. Radiation hardening techniques and shielding can help a lot.
