The main image say "911, what's your emergency?", but in my experience they have always intro'd with "911, where is your emergency?". I wonder if there was a protocol change where they figured that the location was the most important piece of information in case the phone call got cut short.

Indeed, the article mentions that this was "released into the environment by the pharmaceutical company, GlaxoSmithKline".

I originally read about this at this excellent site I'm following for Ebola news, http://promedmail.org/ (and also now using to learn a lot about plant pathogens etc.)

Their item quotes a source with more info and has some very good editorial content on potential problems, including details on recent downstream outbreaks: http://promedmail.org/direct.php?id=2771817
All new App Store apps with embedded frameworks are broken
Yeah, you'd think they have strict procedures for release of live virus in the environment.
to be honest all you see there are features of the APM, which is also sold by 3DR and developed by open source enthusiasts + 3DR.

The features have been there for a couple of years now albeit they've been improved and made more and more reliable over time.

That includes stuff like follow me (follows phone gps coordinates) auto land, auto return to home point, etc.

I've had an APM board (well, many APM boards really) along other boards for flight control since many years.

Now they sell is as a board called PX4 which is more powerful but uses the same software (but should evolve into something better than the APM).

In reality tho stuff like follow me doesnt work as well as on the video. The short 3s extracts are best case scenarios.

The main issue is that it cannot track the subject (no image recognition) so it really just follow some gps location and hopefully the camera is aligned (it auto aligns it depending on the trajectory, else you need a copilot to care for the camera).

Funny trivia, a large amount of kick starter projects with their "awesome" return to home, follow me, etc are using the APM board and the APM is the only reason they even get support... except the APM is free/opensource hard and software.

DJI being an exception, but their board isnt as full featured as the APM/PX4...

Finally, remember that these helicopters fly for about 15min and are still relatively prone to failure and interference. we're far from reliable large scale reliable delivery, mass governmental use, etc.

A 'basic' CPR class for the layperson includes CPR for adults and pediatrics, using an AED, and the Heimlich Maneuver
Sounds like the transmitter would be in violation of part 1, then. And I guarantee it's got a sticker along those lines somewhere on it.

My understanding of #2 in rule is that it's meant to protect against incidental interference causing complaints to the FCC. If the ham operator across the street makes your TV/dental fillings act weird, you can't ask the government to go shut him down.

In any case, it also probably depends on the precise legal definition of "interference", "must accept", and so on.
Nothing you could not do 10 years ago without any kind of remote video or automatic piloting.

People associate drones with multicopters. But really they're UAVs.. or.. you know, what you call drones, and can also be planes.
small/cheap (800USD) electric powered planes can go about the same speed as an airliner at take off, that is, 400km/h.
any faster and it needs to be turbine powered.

Also you'd go the opposite way (toward the plane) so the speed dont matter much...

Now, good luck to aim for the turbine - for all turbines, at once.

Hi dear Hu Miao,

Sorry for disturbed you. We only send this news to those who have asked me for help previously.

Since you have emailed me a question about Mou in Augest 21, 2012 (I anwsered your question immediately), we thought you'd be interested in this news and you might be glad to help us.

We're not trying to spam.
If you make it a lot bigger it flies a lot longer (40min for a 4kg multicopter for example )
If you make it an airplane it flies a heck of a lot longer (1 or 2 hours for a <1kg foam plane)

So yeah.. batteries need to get magical or our power usage efficiency needs to get way better.
I'm not really gonna go to deep into it but my personal feelings are a false positive would be infinitely worse.

Those drugs they give you do shit to you. I've been permanently altered from taking them when I was in my adolescence (I can remember feeling _significantly_ different pre and post drugs, and I've been off for many man years). There's a reason I'm not very keen on the "keep trying them till something sticks" approach that we take with this crap. Especially with developing individuals.
Someone solving these problems will have a product in great demand.

Cool. I guess it was naive of me to visualize a piece of colored glass. :)
My mom has Alzheimer's disease. I either sympathize with your situation, or if you were using it as an expression, I find the misuse a bit offensive. Particularly in this context for me, it brings up a painful memory of one of the first signs of Alzheimer's in my mom, when she called me because she had entirely forgotten her computer password.

As a sidenote to anyone reading this, I really appreciate that the Hacker News community occasionally posts and upvotes Alzheimer's articles. I read every one that I see.

Anyway, I beg that you might not use "Alzheimer's" as an expression for forgetfulness, just as you might avoid calling someone "ADD" when they multitask to a fault.

Awesome write up! I do own my blog engine and I'm not planning to change anytime soon.
Your parents are like your investors in a hostage situation. Convince them. Explain to them what you're doing. Show them examples of other people doing it. Tell them your goals and hit them. Get them involved to some degree. And work really really hard. Don't slack off at all until you're paying your own expenses. No drinking beer and playing video games all day on their dime.

You've correctly recognized the opportunity you have. Not having to worry about living expenses has been the key ingredient in a lot of successful careers. You're ramen profitable on day one. Do something useful with it!
Indeed. And so it is a little disingenuous to point to narrow gains in one area in a discussion of broad gains, is it not?

$10,000 Car – That Runs on Air
A smooth transition for society would take the cooperation of a government, the business leaders, and the labor force. That just doesn't seem like it will ever really happen in America, but I'd be hopeful of some other countries (smaller the better chance I'd guess).

Business will just keep seeking profit until the social issues start affecting them directly. That's just what they do best.

>I know it is a fairly complex problem as I have a hard time finding skilled developers for example

Start picking up some of those junior developer applications that you get. Obviously that's not the courier and printer guy, so maybe I'm missing your point, but a lot of the difficulty of matching employers to employees is the high (sometimes ridiculous) demands on the applicants because the employers believe they have the upper hand in the market. Appraising developer skill can be tricky business anyway, so you may have passed up the guy who can fill the spot if you're only checking to see if they have a few years of experience.
Funny; the essay made me want to go a cruise even more! I still agree that it is one of his finest essays. I rank it up there with The String Theory, which is my personal favorite.
The slow speed of the display would be very distracting, I think. If you watch the video closely, you can see that he pauses for 500ms whenever he touches an on-screen button. This seems like it would be annoying in the long run.
lol, great point - fixed that
I was being kind of sparse in details, sorry.

Having a material that can self support itself into orbit can potentially unlock practical variations of:

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

whose main problem is:
The simplest design has a pressurised water tank where the water is heated before launch, however, this gives a very low exhaust velocity since the high latent heat of vapourisation means that very little actual steam is produced and the exhaust consists mostly of water, or if high temperatures and pressures are used, then the tank is very heavy.

Although, that would also require the material to be very heat resistant as well. Which might be problematic. Compressed air might also work at that sort of level of material as well. At least for initial launch stages until you need to switch over to another type of propellant (or a more controllable engine).
This is for legacy reasons dating back to the time of the 8086 processor. Basically, the 8086 could only access 1MB of memory. In this one megabyte, the BIOS would store a lot of data structures (necessary for accessing disks and setting the video mode). When the first 32-bit processors came out, the original 32-bit operating systems still needed to make use of the BIOS in order to do things like change screen resolutions and enable graphics. To do this, they needed to leave the lowest 1MB of space intact and memory mapped to the corresponding physical addresses. Executables had to be based above this 1 megabyte in order to not overwrite the BIOS. 0x400000 is hexadecimal for 1 megabyte and so executables are often times loaded here.
This looks very interesting in the same way as Clojurescript but with F# and potentially a smoother experience.

Has anyone used this that can provide some insight into it? Does it work with entity framework? OWIN? What's the story with the F# to javascript compilation; did they invent that or is it another project? Who are these people?

I think it's a shame that the C#/.NET ecosystem can't seem to have FOSS nice things because it really hampers stuff gaining traction. However I find the open source license for this is very clear and generous; I still can't seem to figure out if ServiceStack is safe to use :| This should allow for learning the framework and providing nice things to the community, and then the licensing seems reasonable compared to the value proposition for working on commercial software.
Thanks for this! I want to write my own.
In this context, how about something like this?

"Don't repeat yourself (As Much as Possible)"
That situation is just about as maddening as that site's scroll behaviour.
It's worth noting that the author appears to be in Greece. Assuming he's a non-native speaker, it doesn't really make sense to be "offended" by his misuse of the term.

Maybe a better way to put it would be "We don't typically use 'Alzheimer's' to refer to forgetfulness because it brings up negative emotions for some people."
The issue with rockets is that it takes x amount of fuel to get to your destination once in orbit and x amount of fuel to get the craft and the destination fuel to orbit.

It's why rockets generally work best in stages (you just drop the extra support structure needed for the fuel). It's really an exponential problem. Every lb of infrastructure you remove from the rocket makes it _much_ more practical.

See my comment above about having magic space elevator materials available anyway. Steam rockets and the like start to seem very practical at that point. And probably less insane than a cable all the way to space.

Not quite what I had envisioned when I talked about a global response team. I guess thats why we don't have a global response team. :(

And thats not meant as an anti-american comment but rather as a realization that countries don't get along all that well.
To be fair, nobody at LargeCorp wants to stay late to interview someone who probably won't even be on their team. It's a chore at that scale

Ignoring, of course, that (a) they've probably used or heard of ReSharper and (b), both F# and C# pronounce the hash as "sharp"? ;-) I suppose it could be confusing but it wasn't the first thing I thought of...
Triple-Es don't have to fly. Key difference.
I've definitely seen it happen, so saying that it isn't true is not very honest. For instance, I distinctly recall a post a year or so ago where someone complained about a YC company that had ripped them off, and PG replied saying he was killing the thread and quoting the penultimate paragraph of "In submissions" from posting guidelines (https://news.ycombinator.com/newsguidelines.html).

Maybe you don't enforce it as hardly as you used to, or maybe this thing I saw was a one off, or maybe that guy at the time had crossed a starker line; regardless, saying that it isn't true is misleading.
This could become the new trend, as populations concentrate more and more in cities, creating slums, the conditions to catalyze outbreaks increase exponentially. I agree with the author that the cause of the recent epidemic has to do with the geographic location of the initial cases.
It shows that exercise is great for the brain. Any exercise. Of course, there's different kinds of neurochemical reactions to aerobic vs. strength training, but in the end both have positive effects.
No. #and_then here is monadic bind (>>=), and is necessary for all three use cases he described - nested nil checks, nested iteration, nested IO actions/callbacks.

Whether it's expensive or not depends on your point of view:

"Interestingly enough, someone in the audience also asked about the price point. Cross replied that the comments break down into two distinct camps: FOSS people say "wow that's an expensive laptop" but FPGA users say "wow that's so cheap for a development kit!"

You probably don't work as a malware analyst. This is a perfectly fine analysis.

Malware has been spreading the same way it always has: phishing, social engineering, application exploits. It's very rare that you actually see a new infection mechanism or a new zero-day just for a particular piece of malware. That's what makes malware like Stuxnet extremely exceptional.

You're forgetting the square-cube law. Or rather, in this case the linear-square law. Think of each bit as a square, with side length 1/n. Oversimplifying, but the basic principle is there.

The total amount of data the laser goes over in a second is proportional to n - because it's related to how long the laser takes to get from one edge of the square the the other edge. But the total amount of information stored goes up as n^2 - it's related to the area of the square.

Or: to put it another way, the number of tracks also goes up when data density increases.

(This also happens with hard drives over time. Recent hard drives take a lot longer to read or write the entire drive than older ones. See http://tylermuth.wordpress.com/2011/11/02/a-little-hard-driv... for example.)
"Does it work with entity framework?" -> It works with whatever .NET db tool you want to use, it's entirely agnostic in this regard.

"OWIN?" -> It can, with WebSharper.WebAPI [1].

"What's the story with the F# to javascript compilation; did they invent that or is it another project?" -> It's an in-house developed compiler.

"Who are these people?" -> A Hungarian company called IntelliFactory.

(full disclosure, I work at IntelliFactory.)

Just ask the Amtrak people and they will give to a realistic expectation.

The issue for east-west trains is that the track usually owned by CSX or another freight railway, and the thousands of tanker cars heading for Albany, NY for transfer to barges to New Jersey oil refineries have priority over everything except the trains that bring in produce from the West Coast.

I frequently ride Northeast corridor trains Amtrak owns 95% of those tracks. The trains to NYC usually run +/- 10 minutes of schedule, depending on the number of people embarking at midpoint stations.

Of all of the transportation providers that I deal with, Amtrak is the lowest hassle and best experience. Consistent pricing, no security theatre, comfortable cars and friendly staff most of the time.
