"Has there been a controlled test where someone flew a drone purposefully into the rotor of a helicopter?"

I'd be curious to know that. (It reminds me of the apocryphal chicken cannon story http://www.snopes.com/science/cannon.asp)

A few things to keep in mind though. The incident here was at "700-800 feet", the chance of the heli doing Vmax at that height is pretty small (although in this ase it was described as a police heli chasing a car, so _maybe_ it was getting along a a fair clip?). A quadcopter owner in general is pretty motivated to _not_ have his expensive toy smashed up by aviation traffic, in much the same way as birds probably try pretty hard to dodge planes/helis.

I think too many people are miscalculating the risks and consequences of "drones" - and it mostly bugs me because they're toys I enjoy playing with (which make me somewhat likely to be doing that miscalculating wrong as well, in the opposite direction…) I also enjoy riding motorcycles, and theres a fairli locally-famous quote here from one of the very senior motor vehicle bureaucrats saying "If motorcycles were invented today, we'd have banned them immediately." In retrospect that would have been "wrong" - motorcycles are "dangerous", sure, but about the same order of magnitude of dangerous as high school football or horse riding - activities which we as society deem "a bit dangerous but perfectly acceptable".

And while I know neither you nor I have a dog in the US public opinion fight, I find the hysterical handwringing over the dangers of hobby drone immensely hypocritical from a country where 2/3rds of the elected politicians are deeply in bed with the NRA, and there's an entire industry profiting largely from locking young black men up for use and sale of pot... When the "drone" accident rate approaches within say three orders of magnitude of, say, the drink driving accident rate or even the falling-off-ladders rate, perhaps the media hysteria and the calls from non-participating parties to "ban it all immediately and lock everybody up!" just make people look ignorant and spiteful.

(And Jacques, not sure why I'm currently engaging in "robust discussion" on at least two threads in HN with you right now - know that I respect you greatly, while disagreeing occasionally...)

As someone who's married into a different "ethnic" family, the palate difference (at least for us) is incredibly wide on both sides. I can't really stomach most authentic Chinese food, and especially can't deal with the flavor and texture of the desserts.

Likewise, my wife's family can't handle traditional midwestern dishes, nor traditional soul food well at all.

That's just been my experience of course, so I'm not claiming it's indicative, but it's actually the hardest part of our marriage (which, is a good thing, I think).
It's rather unexpected. Browsers carry so much baggage that you need a private mode, I wouldn't have expected something like ssh to have this sort of problem before I read about how it exposes your keys.
As much as I want to say yes (I would be horribly excited to work with Clojure) it seems to be something of questionable value to a non-engineer.

Depending on the application there is probably a productivity advantage and you're certain to find a small number of very talented engineers. After that you may have to train engineers. If its a more interesting / profitable project you can expand the hiring pool by looking globally. Famously, Jane Street uses OCaml and it works out well for them.

I'd say yes in two scenarios, if you want a smaller team (and dont need to scale up too much in number of engineers; although you can switch languages later if the company begins to succeed) or if you have a more specialized project that benefits from the language and probably needs more of an academic background.
Depends what you want to call a solution. Sure, if a manager bullies me into something I'll either do it or not. But I'm definitely raising this with his manager and/or looking for another position at that point. I'd call it a bad workaround for a current problem, not a solution.
Um. It's not really about whether or not you like or dislike turkish delight. Its about your imagination when you thought about the dessert you would most like to have. I was young enough that for me it was a turkey based savory food and not dessert at all. It's not that turkish delight is bizzaro or exotic. It's the contrast between what you thought and what it is.

And it confirms exactly what I said. Among the first three results :

> all skills are very related to how they're treated.

Of course not, and that's my point.

Doctors are all paid the same in the UK, without any consideration for skills. Those who emigrate and get better pay, are paid better because they emigrate, and not because they do or do not put patients first.
If someone is literally dying in your duty of care because noone can access any patient records, that sounds tortuous to me. A bit like the Stanford prison experiment, but replace the guards with IT contractors, and the prisoners with surgeons, doctors, and nurses.
> No, I find it unreasonable that not everyone knew the schedule beforehand, or that someone who knew about it didn't raise it as a problem.

The problem in this case was that the meningioma's MRSA positive culture results (from the first, cancelled procedure day) came back on the day of the rescheduled procedure, and that necessitated a schedule rearrangement (placing the meningioma at the end of the day) that the substitute anesthesiologist objected to. The author points out the absurdity of the situation re the MRSA culture when, if they had performed the procedure on the day originally planned, they would not have the culture results and so would not have done a post-op decontamination, but the rescheduling had forced the additional step. I think one does the best they can to budget for unexpected problems as had happened in this case, but in an overworked system, that cushion is among the first things to go.

> This should never happen right before the operation. At that point it's too late and it's on everyone to deal with the situation at hand.

Ideally, yes, one catches complications before they are a problem. Experience suggests complications still occur, and the only solution is to "be like water" and adapt.

> What I'm pointing out that if the plan was a surprise then it's completely understandable that someone says no.

Not for a physician. It is understandable for a physician to be ticked off, it's understandable for a physician to call in a favor and find someone to cover for them, but it is not understandable for them to say "no". The substitute anesthesiologist not only said no, but was apathetic to finding someone to cover for her. To that, I respond as I did before, the expectation from what I term the old guard of medicine is that your duty is to attend to your patients. Younger physicians, such as the anesthesiologist in question, would seem to share your perspectives on work scheduling, and the old guard say that the result is decreased quality of care.

> As for solutions, it depends on a hospital, location, patient's state, available team, etc. Lots of possibilities. (BTW, anyone shouting at anyone else is not even close to a solution)

That's a lot of handwaving. Keep in mind that in medicine, you can only kick the can down the road for so long, and that in this case, the patient's family had rattled legal sabers over the first cancellation. I suspect the possibility space is not as large as you think.
This has to be the nicest, most reasonable-sounding ad hominem argument I've ever seen.

But it's still an ad hominem argument. Is there any way you actually disagree with the post? What would you say to Dr. Hsu if he were in the room?

Also, what is your evidence that he's not in touch with experts in psychometrics and human genomics? I don't know him, but I have very much the contrary impression.
haha like codecademy before it! They get so mad when you say "Code Academy" too - still wonder why. That domain HAS to be available.
Hyperbole is a problem.

>Or am I just being a sensitive ninny-nanny?

At least a little.

When we describe mundane things as extreme "I'm _starving_ the slow service at this restaurant is torture" or extreme things as mundane "enhanced interrogation techniques" we lose a little bit of our ability to correctly communicate and even experience the world.

Being in awe should be a rare and wonderful state, but instead it's apt to describe a free sandwich as awesome.

The problem: lazy people with poor vocabulary (and education) and bad journalism and editorial work.
These don't work on all networks. Like classified networks.
Just trying to point out a seeming lack of perspective. Not trying to derail things (but, in retrospect, I suppose that argument inevitably would get misconstrued, even if I'd made it well.)

People fear drone incidents may possibly harm or kill someone - without any concrete evidence of actual harm.

But threaten the "right to arm bears", and from some corners all hell breaks loose.

How does that work? Why are drones even something that gets discussed in the context of improving personal safety when there's _so_ much other low hanging fruit where real differences could be made?
So have I. CACs don't work on classified systems though.
"The key features of a tech start-up are this: it has no customers and a strong chance of going broke. What most of these businesses do is funnel capital (investors’ money) into work nobody asked to be done. They build a product for which there is no market, exhaust their funds, close. They’re a bit like a make-work project."

"I'm sorry to know that there are people forced to live day by day in a high pollution environment though."

It's funny, for > 99.9% in Beijing, they have no reasonable way to escape, due to family ties, personal financial disruption from having to leave a job/career, etc. But there are many (not only foreigners) who could much more easily uproot and move to another city or another country.

The thing is, you go on hoping it's going to get better over time, and pushing the decision further out, as 'another few months' of this pollution isn't going to make a serious health difference.
Compiling to llvm brings a giant complicated build time dependency and it is not pleasant to emit it as plain text due to some strange design decisions.

People are also more familar with C, it works on more platforms, and doesn't require any familiarity with SSA.

I think you only really need llvm when you want to get into debug symbols.
Then I guess you don't work on any projects that only want to see non-whitespace changes.
Ciao flashman this is a really intelligent suggetion I never took in consideration I will immediatly estimate the code effort to make it as you say
Surprisingly enough, I left a comment on the parent thread(above) and then lo and behold scrolled down & found YuHoung talking about me (huh... i don't know him, yet a few weeks ago before I was on a TV show (does he work for their production company?) I saw that he left a comment on my blog post linking to my comments here).

I don't consider this to be a fiasco... it just goes to show how important having the right connections, people and their money behind you(as an inventor I have struggled making those connections, though have & continue to try). You can go and meet a huge tech company, but don't expect much without having a ton of users/downloads and or people with a network & their money driving your success. Though, even at times with the money and connections similar things happen; there are YC alums with similar stories.

More then two years later this meeting was my first of others. I learned a lot from it and later realized our tech didn't work while demoing it because of their corporate firewall. An issue we later ran into with another client, so we were wrong to think it was something on their end and again you won't find any audio sync technology in the Moto X.

Well, I'm just going to keep on doing what I love to do and feel I have a knack for. If there are other technologists or biz guys will solid networks out there who'd like to talk shop and potentially work on some projects together (adventure awaits us) I'd love to hear from you (ryan (at) speakerblast.com or @ryanspahn on Twitter).

As a matter of fact, I have, and several times. Don't assume I know nothing of what I am talking about please.

Please show me the stats of lung cancer in Beijing vs other parts of the world. I'd like to see how much the reality stands out vs the assumptions people make.

> If you think that is not "getting sick", then well, welcome to Beijing.

I was not talking about discomfort (that, I have noticed on every trip I did there) but this particular article makes blatant claims with absolutely no data to back them up, which was exactly the point of my post: allegations do not create facts.
I wish I had learnt to play when I was younger, i.e before my teens. I learnt as a teen while in secondary school, and it came at a time where I needed to learn some mental discipline.

In high school we used to coach younger kids from a neighboring primary school. Some kids would be all over the show, but the ones who did well picked up quite well. A few of them made provincial school tournaments, and fewer would make nationals. The gap in our training would then be apparent at that level because they'd be playing against kids who are learning enough chess theory, i.e endgame theory.

We once had someone in our team leading in material, but fail to mate her opponent, so sad yet funny because it was like a witch hunt, chasing the opponent king all over the show with a few pieces. We hadn't taught them some endgame tactics.

I think chess is one of those games that many people should try out. I'm glad I had a friend in the game when I went through painful teenage years.
To extend on that, from what I have heard, fans of DCSS should check out Desktop Dungeons (I liked the original, which is free, but the new version is also worth checking out).
This is a problem with a lot of paginated sites, such as Tumblr, various forums, and comment pages. Anything that's ordered from newest to oldest won't have a constant correspondence between URL and content.
"Come on, the article referred "you could get sick just by standing in the street" - if that's not hyperbole, I don't know what that is."

Actually, that's understatement. You don't even need to be standing in the street.

Air circulates everywhere, both indoor and out. Sure, you can try and seal your windows, and run air purifiers in your home. But what about when you're at work, or at a restaurant, or any other non-home place?

Is that true? I had a circle of friends 10-15 years back who worked in maintenance for Qantas, and I heard about cleanups and repairs from birdstrike often enough to remember it.

I have an uninformed opinion that collisions are not spectacularly uncommon, nor spectacularly serious. I wonder if the magnitude of risk increase we're talking about (by allowing drone operation under current rules, which this incident was not...) exceeds, say, allowing smokers (with their increased risk of coronary problems) to be commercial pilots?

When I was talking about the "fiasco", I was thinking of the "LargeCompanies" account name and the NDA that caused it.
What I don't understand is that since Beijing is also the center of government, how is it that they are not showing more self interest and fix the situation. It's really a paradox.
This is a really interesting post with some cool maps, but it's a little surprising because the author keeps saying he cannot finding reasons. Just that 4-5pm on Wednesdays are high-time for getting arrested in the Tenderloin or 16th and Mission.

I'm sure iPads can be useful, but you know what's more useful? Good teachers.
There are a lot of people who mock others simply because they don't know a domain of knowledge. You can bet that doctors also mock those who don't successfully take care of their health, especially fat diabetics. Anecdotally, I think fat diabetics are the favorite humiliation punching bag for doctors.

Anyways, the issue that stuck out most saliently to me was the cultural expectation placed upon medical staff to work through any issue regardless of personal life, and what must be a tacit management understanding of the situation. Somebody in management screwed up, and now the doctor is left holding the bag, and this doctor unfortunately feels some responsibility to manage the situation. This doctor is frustrated that the anesthesiologist did not make the same sacrifice, and wanted to tend to family.

I don't blame either of them. Kudos to the doctor for holding the bag that management dropped, and congrats for the anesthesiologist who won't submit to exploitive cultural expectations.
In matters of life and death a little bit of yelling can go a long way.
Top 7 Simple App / Game Ideas That Made MILLIONS for Their Owners

The canon story is hilarious :)

I've seen drones flying here that were lifting DSLRs, 8 motors, very powerful and quite heavy. A thing like that would do serious damage just by falling out of the sky, let alone on impact with a fast moving leading edge.

Agreed that the drone risk is oversold. But what bugs me is that these morons that do this spoil drones as a useful and recreational thing for everybody else. It won't be long and 'drone operator' and 'irresponsible asshole' will be synonymous. It would be really nice if with every drone sold there would be a simple booklet stating the rules for the location the drone is sold into and some kind of mechanism that requires you to read that document before you can operate the drone.
And, as an uncontrolled anec-data point. I've intentionally flown one of my ~1lb drones into myself while wearing no more protective gear than a long sleeved tshirt "for science" (ie:just to see how bad it'd be if I got it wrong and hit someone else). It hurts a bit, but I wasn't "injured"...

(I've not has the courage/foolishness to try it with a larger quad, or even with that little one with carbon fibre props instead of plastic ones...)
Disruptive Technology Weekly Roundup – Dec First to Dec 7th
One of the hospitals I rotate in has solved this by having you physically scan your nametag (just like unlocking any of the doors) to log in, log out, and whenever else your credentials are needed. It works pretty well, and no passwords to remember once it's set up.
Birds hit planes all the time, usually no harm comes of it but there was a nice video (which of course I can't find) where you see a jet on take-off ingesting a single bird and having one hell of an accident. It all depends on what gets hit, how fast the plane is going and at what powerlevel the engines are operating.

A bird is a pretty soft item compared to a drone though.
I've had bland cooked beef served in Wisconsin...

Also had relish trays served with uncooked ground beef, dark rye bread, horseradish, braunschweiger, onions, mustard...

Potent chilis may not be a traditional Wisconsin favorite, but there are other strong flavors welcome there.
It's all about the relative speeds. You're standing still, 1 pound is not a whole lot and likely your drone wasn't going all that fast. But if it had hit you in the face it might have been a different ending. Ditto for a helicopter. Hit it against the front glass panels or the canopy, no big deal. Catch the outer end of the tailrotor and you'll probably crash it.

Doctors, particularly trauma and tumor surgeons, have dying patients all the time.

Often there are additional treatments available but for resource constraints. Ordinary folk die of heart disease every day, but somehow Dick Cheney lives on with an artificial heart.

I know being a doctor can be quite a stressful job and requires a certain class of personality. But still it has gone with the territory of being a doctor since the beginning of civilization.

At 35% per 10µg, it's actually about a 900% increase in lung cancer risk. That's a significant effect, because it means 900% more people will get lung cancer on average. People are getting killed, it's just hard to say how many without better numbers.
Amen.

I ran the hub for a BBS network. We had the best offline mail readers back then. The best feature being "twit filters". God I miss twit filters.

If I ever figure out a way to add a twit filter feature to my web consumption, David Brooks will be the very first pundit added to the list.

Eli Pariser alerted us to the dangers of The Filter Bubble. I wish we lived in a world without trolls and useful idiots. Until then, I agreed with Clay Shirky: we need better filters.
Lung cancer has a normal occurrence of something like 60 in 100,000.

If we are as conservative as we can be and say the increase is only 36% from all of these smog days, that would mean that the rate should increase to 82/100,000.

Beijing's population is ~21 million. The 22 / 100,000 increase from the base rate would mean an additional 5,000 lung cancer deaths in Beijing due to the smog. That's the minimum. The more realistic number is surely an order of magnitude or more higher -- this level of pollution is unprecedented in modern times.
