My wife was also in the ER a couple of years ago. She was there for about nine hours. At one point the attending came by and spoke with us for less than a minute. He basically repeated what the nurses and PAs had been telling us for the past few hours. But he clearly wasn't paying attention to the case because his summary was clumsy and lacking in detail. It was no more helpful than what I was reading on Web MD on my iPhone. My wife's exact words when he left the room were, "That was weird." Later, when we looked through the bill from the ordeal, it turned out that this awkward, uninformative, 45-second interaction was billed at almost $1000. If he had told us ahead of time that his unnecessary analysis was going to cost $1000 (even if it was paid by insurance) I would have thrown a shoe at him and told him to get lost. Healthcare is not a marketplace.

I use Vim half the time and ST the other half.

I would never try to push Vim on someone who already uses ST. It is that good.

My only reason to use Vim is editing remote files, or config files.

If someone proposes a Kickstarter project for a mobile developer workstation with a solid design, 4:3 high-res screen, pointing stick, and great keyboard, I'll be the first to hop on.

Or maybe I should go ahead and make that Kickstarter project a reality instead of waiting for someone to.

Chrome does split pages across different processes, and this, as far as I know, makes use of multiple cores. For (I assume) memory overhead reasons, it doesn't put each tab in a separate process by default, although there is (or used to be) a flag to switch to that behavior.

You hit the nail on the head with your question here. This guy does not sound like someone who really know what he's doing in the market. If you had already made the decision that you believe in Tesla and want to invest there is no reason to be buying and selling the stock based off of earnings reports. Particularly if you believe (as this guy does) that the CEO is not particularly concerned with Street estimates. Just buy and hold.

other research groups (e.g. http://rpg.ifi.uzh.ch/) are working on bringing this technology out of the motion capture system by mounting cameras on the drones and use image processing algorithms to estimate the drones trajectory.

The ads on spotify really are unacceptably annoying imo.

And it's not like spotify is the only way of getting music for free
"Legitimate" depends a lot on the environment. Should Spotify be pushing bits out to the world from your doctors PC? Should it be accepting inbound connections from other random people around the world?

Now answer the same two questions after an exploit in the P2P library within Spotify is announced on HN.
In terms of this being HackerNews: It is actually a pretty smart and economic idea to use P2P in music streaming clients. When I first heard about this, I was excited. Thumbs up, Spotify!

Apart form that, that's really no news, you could read about that for years.

I guess I'm getting old, but the demo both looks and sounds like a man virtuoustically playing a pair of typewriters.

More seriously, I think this is cool, but a little overblown in someways, we've technically been able to do this kind of performance (using sliced up digital samples) for a very very long time -- decades. Digital sample machines, of many kinds of forms have been used in live shows for a long time. Think of your favorite 80's new wave band and they probably had live shows with digital synth triggering samples off of a keyboard.

I think this is more of a cultural shift than any kind of technological shift, but interesting nonetheless. The methods of playing these things is much more akin to being a drummer or an old school DJ scratchoff than anything else. But just like complaints about all modern music being overcompressed, these guys have to work off of only two performance vectors: sick beats and cool samples. There's no dynamics in the performance or playing with tonality. Glissando, spicatto, breath control, tonguing, etc. are all right out the window.

Music has been reduced to learning and playback a la guitar hero. A generation of musicians, messing around with samples from music they themselves could never perform.

We talk a lot about technology we no longer have the means to make and knowledge lost in fires and wars and natural decay, and toy with that idea in sci-fi and real life. However, today we certainly have a much greater pantheon of fantastic accomplishments in these areas.

But I wonder if we should consider a similar phenomenon with culture and cultural skills? We may be entering a time were previous cultural knowledge, like how to play piano virtuostically is lost, exchanged with how to play a sampler at similar high levels of skill. We may have lost the means to transmit that culture forward to future generations, but outside of a vague sense of loss, nobody really cares because what we have now is also vast and complex and has its own set of interesting skills that need to transmit forward.

Is this the cultural equivalent of cleaning out the memetic closet to make room for new stuff?

So, this post has a number of errors, and is fundamentally wrong.

(a) pthread_mutex_t and friends use futexes, which only call into the kernel when there actually is contention.

(b) it would be better to use chrt (change to real-time priority) than the maxcpus trick, because the former accomplishes the same thing, but allows the core to still be used if the high-priority thread suspends (e.g. to do disk or network I/o).

(c) Contrary to his claim about Snort, there is no reason to prefer a multiprocess design over a multithreaded design for a particular application. There is no savings in overhead or synchronization or anything like that by going with processes. In fact, using processes and then using memory mapping to share when you could use threads, is just making things harder for yourself for no reason.

(d) What I’m trying to show you here is that “multi-core” doesn’t automatically mean “multi-threaded”. Well, in computer science terminology, a thread is a schedulable entity, and a process is a schedulable entity with memory protection. So, he's wrong. Lots of developers talk about threads and processes as orthogonal things, though, so I can see why he made that claim.

(e) The overall theme of my talk was to impress upon the audience that in order to create scalable application, you need to move your code out of the operating system kernel. You need to code everything yourself instead of letting the kernel do the heavy lifting for you. That is horrible advice that is just going to lead to lots of bugs and wasted effort. It's premature optimization. Even most people using the Linux realtime preemption patch (PREEMPT_RT) do not have such strict requirements that they need to take this advice.

(f) Your basic design should be one thread per core and lock-free synchronization that never causes a thread to stop and wait. Might apply to certain very specific real-time (as in, embedded systems or HFT) scenarios, but in general, no, you're just wasting the core when that one thread doesn't need to use it. Prefer real-time priorities if you really need it.

(g) Specifically, I’ve tried to drill into you the idea that what people call “multi-threaded” coding is not the same as “multi-core”. Multi-threaded techniques, like mutexes, don’t scale on multi-core. Again, you can only use multiple cores in parallel if there are multiple threads. And multi-threaded techniques do scale. You definitely may want to use lock-free synchronization instead of mutexes in some specialized scenarios, though.

EDIT: OK, here is one other thing I forgot in the list above.

(h) There are multiple types of locks, like spinlocks, mutexes, critical sections, semaphores, and so on. Even among these classes there are many variations. Technically, mutexes and semaphores both are ways of protecting critical sections, and a spinlock is a way of implementing a lock (including, possibly, a mutex or semaphore lock). Again, this is to some degree the difference between developers with a shared lingo and computer scientists. But if you go by that kind of lingo, you're missing part of the picture.
Yeah let's not do that again. :)
PushBuilder: gem to construct JSON payloads for Apple push notifications
I really hope that running a chroot or vm becomes a fully supported part of chrome os along with an x server. Working with a crouton ubuntu chroot on my (free) chromebox feels a lot like using OS X circa 10.3 or so and I would consider using it as my full time dev box if autoupdate worked in dev mode. I think i would actually prefer it to modern os x if I could tweak some keyboard shortcuts and run an x sever (even an annoying one like apples) mixed in with aura instead of having to switch back and forth.

It's fine if you don't find this amazing. I do, and I think many others do too.
My blog post was quite clear that I'm talking about futexes, and then when it fails to get a lock that it goes into the kernel. Seriously, that's how everyone did it from Solaris to Windows before Linux "invented" the concept AND it's been in Linux for a decade. When somebody says "mutex", you have to assume they already mean "futex".
I just calculated that I'd have to saturate my (normal-for-UK) ADSL uplink for 7 months to upload a terabyte.

You are missing something. 2 things, actually.

Cache and instruction set.

Intel is still more powerful than ARM because of its instruction set.
I still think Ruby was made by someone who learned Perl and Lisp, but never managed to really grok Lisp macros.

That's not bad, as Ruby is a very powerful language.

Sorry it is not clear. I tried to express it but obviously didn't do it well enough. Here's another try:

The best products in the world are those created by organizations that start with the customer. Everything they do starts with customer needs, pains, desires. They work backwards from that. Eventually they decide what tools & technologies to use to deliver greatness to the customer.

Write Once... encourages a mindset that doesn't start with the customer, but with a technology. Instead of focusing on the features & capabilities that matter the most to the customer, the focus is on something like HTML5 (or Java).

The best products result from focusing on really delighting the customer by doing a few things really, really well. Given mobile platform fragmentation one axis where this is critical is what platforms to support initially. WORA (esp HTML5) leads to a mindset where it's important to get the experience running on many devices simultaneously; the 'focus' is on doing a crappy job across many things.

I'll repeat what I said in the article here: I don't hate HTML5. I code HTML5 almost every day. The product I launched on Monday makes heavy use of HTML5. But only because our customer value proposition led us to the need to build a website, and we had capabilities that needed to be highly interactive. HTML5 is a great technology that addresses this.

The summary: If you must target multiple platforms, focus on the experience; then try to get code re-use. Don't do it the other way around.
The system uses an external observer and external computer to track the bots and make decisions. Implementing this in a civilian setting would be much more difficult than simply making the bots larger.
It's interesting to see all the people on here saying that there's no point to having a beefier machine to "just browse the web" and then see your comment which would appear to indicate that there is a need for more performant web-browsing devices.

They have been in civilian (private/commercial) use for a few years (since 2008 or so). Mostly for taking pictures from above -- they are relatively well-suited for that. (And for fun flying of course)

For transporting big things: it's more efficient to have larger rotors than to have multiple rotors.

For transporting really big things: see above, and helicopters have been around for a long long time; "we" (not me) have decades of experience with helicopters; you probably really want something that is safe and reliable. You can't just scale up your model.

As for quadrocopter piloting: right now, all pilots crash. Repeatedly. Luckily, repairs are cheap (unless you happen to carry an expensive camera). For a full-size aircraft, crashing is probably not an option, so add lots of dev/testing time for safety features and pilot training.

BTW (somewhat unrelated): One huge problem with (smaller) quadrocopters is the many people that start new copter projects and get nowhere instead of contributing to one of the existing major projects or reusing its soft/hardware. Some of these projects are already way beyond what a single person or even a small team can achieve in a few years work.

[EDIT: Immediate downvote? New personal record! HN is becoming more and more liberal I guess. Never mind.]

Once again, there are many opportunities for improvement. Business opportunities.

Healthcare is plagued by inefficiencies, over regulation, and "just think of these people who suffer" mentality- basically, we undertreat, overtreat and in both case overspend because of inefficiencies caused by overregulation, just because we don't have the guts to say "no". (the fear of prosecution might also help.) To those who are so worried about people being left to die in pain as the result of a "no", just think about how cheap morphine is. There is no need for pain and suffering.

It might take a long time to solve all these issues, if it can be done at all, but there are many good ideas thrown around.

Price transparency - ie knowing in advance how much a procedure will cost depending on the most possible outcomes would help. It should be mandatory - for the most typical stays, give a detailed pricing in advance then let the market solve the problem.

Ending the price discrimination would also be a great thing. Same service = same price. Insurance are getting low costs not because of their "volume purchase" but because they use their market power, as oligopsonies, to get the low price they receive, subsidized by the non-insured.

The current incentives make sure that the minimum is being done (if only to code and bill for that - like the chest X ray in the example. If it was not billed, how certain would you be that it was performed 100% of the time?) and it is a good thing, because I am more worried by undertreatment than by overtreatment. The latter may only cost more, but the former may cost more due to delayed proper treatment and may cost lives.

As shocking to my libertarian values as it can be, I recently came to the conclusion that subsidized first line triage should be offered, not even at costs, but for free.

Healthcare has an information problem - it's hard for patients, especially if they are uneducated, to determine how grave their symptoms are. Even if they are intellectual and successful - so don't think it can easily be solved by education. Read about Don Rosa eye problem, how he delayed treatment for a grave retinal disease.

In economy, self rationing is usually good - but when that decision is based on a lack of proper information of the consequences and their future costs, it's not.

I'm not suggesting to provide free treatment here - just at least free information. A right diagnosis, upon which the patient can decide what to do.

Markets work best when some basic conditions are met. There is no real market in healthcare at the moment because prices are not published, and the information asymetry, while less important than before thanks to the internet, remains strong.

Once we have a medical tricoder and an ebay-like place for medical procedures, I guess the situation will improve.

[medical tourism is a step in the right direction, but even discarding the information problems, until prices are properly aggregated and compared, it won't be enough]

You absolutely should have gone on a date. Think of it this way, if by some chance it worked out you'd probably have the best "how we met" story of your entire social circle.

While I don't doubt Play is useful (I haven't personally tried it just yet) I've noticed big tech companies seem to be wasting their time building new frameworks instead of helping improve already existent frameworks in need of new ideas and fresh eyes. Why a new framework? Is it really not a straightforward process to contribute to an already established open source framework for your desired language?
Insightful post, but, there are services (disclosure: I work for one) that help do all of this for you. The time required to do the steps in this article is insane. Much less your actual product and shipping costs. Seriously, there are better ways to do this — see printfection.com
This is only sad for 3 reasons:

1) Somebody spent the time, effort and likely funding to do an aggregate study of a craigslist Missed Encounters board.

2) This foolishly unrepresentative sample of the american populace is being referred to as a "scholarly study".

3) The author of this article is using this to make broad generalizations about the american social atmosphere based on the aforementioned unrepresentative sample.

I suppose i should sit back and watch this silliness get plastered around facebook ad nauseum as people who don't know anyone who knew craigslist has a "missed encounters" page talk about the facts of their states' social climate.
I have no dog in this fight, but surely it's hypocritical to slam PrivCo while taking the anonymous commenter above at face value. The company is apparently posting further down on this thread -- why not just ask them your questions directly?

This funding round is going to play out in a way that will make it very clear in a few months who nailed the story and whether this reporting is malicious. If PrivCo is guilty of systemic fraud or extortion, there are surely online discussions that can support the claim. As a web entrepreneur myself, I also find the anonymity here puzzling for another reason -- if I had a legitimate grievance with the company I would be doing everything in my power to inject my story into the national media at this point.

I own a Series 5 chromebook. It's hands down the worst machine I've ever owned. I really wanted to like it, too. My issue is that I tried to use it for stuff like reddit, youtube, and whatnot, and because it has no swap space it would just kill background tabs once I had more than 3 or so open. Basically it's a machine built for browsing the web, but because of the way I (and possibly others) use the web it's not useful for that purpose.
