> Gasoline tanks aren't 100% full all the time, either.

The less gas a tank has, the more dangerous it could be. It's a common mistake to think a close to empty tank of gasoline is safer than a full one when the reverse may be true because of the fumes.

For example:

Why focus on the negatives? Just think about all the jobs it created.
I don't have numbers on how much force a typical skid plate can withstand without damage, but I would be willing to bet that 25 tons of force at a relatively small point of impact would be extremely hard to design around without some major drawbacks (weight and ride height, mostly). Considering this is such an uncommon experience. designing for such an edge case and accepting the drawbacks might not even be acceptable.

It sounds more like they're congratulating themselves on designing the failure to be so easily contained.
I'm really surprised that he left out i3wm. It's lightweight and the tiling placement is surprisingly intuitive and simple.

Here's the Google Talk:

I would imagine it would be pretty slow, but you could have a video stream write to a canvas element at regular intervals. You could analyze the pixels in the canvas to look for a pattern. This would be the hard part, since you'd have to write an engine to detect edges and create a hash of all detectable objects in the frame, then you'd have to match each hash to a known hash of the desired object. To get the known hash, you'd likely have to feed in many example images of your object and create hashes from these.
> In making that claim he's presumably assuming that the battery design prevents a cascading failure where the failure of one battery module causes adjacent ones to fail in turn. He's also assuming that there's no external factor that could cause all the battery compartments to fail simultaneously. It's partially PR fluff in other words.

Maybe. When the dreamliner battery fire happened, had quite a bit to say regarding batteries and cascading failure. He's surely making some assumptions (such as discounting an external factor as you state), but it's not like he isn't on record asserting they have put some effort into preventing or mitigating this exact problem[1].

Small world indeed. Hey Rob -Kelly
We are comparing tail events with low probabilities.
I actually think that spinning up a momentum wheel is fairly low energy, but it's been a long time since we did that.

Like I said, if they locked together you could get movement from a huge cube. But I think the key in these guys is to build dynamic rigid bodies and have "joints" that move around to connect them and help them actuate. That'd be awesome.

They could also snake along the ground doing a chain where one goes from the back to the front, then the next and so on. Anyway, pretty cool idea to start from. I can't wait to see if they iterate this and add cameras and a main controller or anything like that!
Hard to argue against Elon's last sentence, though.
I think that's just his tone... (at least, his blog-tone).

It would have been nice to include a little, more personal, summary. Something like:

In this extreme test, we feel that the car performed as designed and we are very happy that the car owner safe.

Edit: the original parent said that the tone of the Tesla posts seem defensive. I'm not really sure what was wrong about the comment... they do seem a little defensive in tone. (Often understandably so...)
Ask HN: Is a Chromebook one of the "safest" laptops to use?
This is assuming that one would solely use an external HDD, and not cloud storage. Although, one would still have a Google account. However, an individual could just browse as guest at all times.

This is not taking into account using Tor.
Good questions, there are disagreements on those points even among libertarians. It's tough to name a single digestible reference because this is such a broad subject. But this one is pretty comprehensive: https://en.wikipedia.org/wiki/Non-aggression_principle
1) Can it be wiser often to rely on ‘fresh looks’ instead of science in our choices? Using scientific findings to make the right choice requires access to these findings, ability to interpret them properly, and certain time investment. Most people can't do that, especially considering that we face a lot of choices.

2) With practices such as meditation, there are no ‘fresh looks’ to judge it by, and scientific knowledge on the matter related to our mind and consciousness seems to be limited. How do I rationally decide whether or not should I meditate?
That's irrelevant.

How is rapid growth and significant marketshare 'irrelevant'?

Even if other vendors put Windows Phone on the back burner, Nokia phones are the most popular by far (according to most surveys 80% of the Windows Phones sold are Nokia phones). If they continue Nokia's tradition of good hardware at low prices, that can drive sales, while the ecosystem grows.

Also, it's not as if HTC is making big profits with Android. They'll probably want to spread their bets.
Perfect safety is not attainable, and this is especially true when it comes to automobile travel, which is probably the most dangerous activity that most first-worlders engage in on a regular basis.

Much of that danger is inherent to the way the system works and the current level of technology and the costs people are willing to pay. A single car maker will never be able to get anywhere remotely close to airliner levels of safety.

That means that Tesla's products will be used in dangerous circumstances, and Tesla customers will die while using their product.

For a normal car company, this would not be a problem, because the public accepts the current risks of automobile travel. The problem is that Tesla is Different and gets far more scrutiny.

Tesla needs to convince people to accept the risks inherent in using their products. Pointing out that people accept the even greater risks inherent in using their competitors' products is a perfectly reasonable thing to do.

If the sample is truly random, it doesn't matter what the population size is. Of course, truly random samples are hard to get.
MongoDB has quite poor in-memory performance due to its simplistic locking strategy. I personally think MongoDB only had the best marketing of any NoSQL database.
Partly matter of taste, partly matter of code formatting style. Used to be big on syntax highlighting for years, but now I prefer mono. When needed, double-click highlights area between matching parens/brackets/braces/tags.
Yeah, I got bitten by that too. There's a list kicking round of all the individual packages required to install to make a haskell-platform-alike. If you want I can dig it out of my ansible config.
Ask HN: Two Sided Marketplace Buildout
As a non-technical person, what is the most affordable way of setting up/programming a two sided marketplace (think Zaarly, Fiverr). I have come across a couple of clone scripts and they are lack the complexity, design and feature set that I need. Paying someone to program this from the ground up the best strategy or are their any code bases/ templates I should know about before I begin hiring a freelancer to finish this for me. Thanks for reading.
Useless editorializing fluff. Avoid wasting your time.
If you're on OS X, I've found Slate to be the best option: https://github.com/jigish/slate

Curious , what are your views on imgur ?
Oops, I deleted the comment you were replying to, because I thought it came across a bit too negative. It essentially said that they always come across very defensive, compared to tech company post-mortems that try to be very factual.
I think the question is how much effort will it take to get all kinds of data from all kinds of sources into a nice, coherent schema.

The "schema-less" aspects of NoSQL data stores is a big part of the marketing appeal, I think.

(Maybe the JSON support in PostgreSQL makes this moot, but that's the thinking.)
Except pollsters put in a lot of effort in making sure that the sample is representative of the larger population.

Which is not true here, as the GP correctly notes.
This isn't really the same thing. Virtual desktops have been around for decades now, and people have been using them like this (with or without two physical displays) forever. It works for the kind of full-screenable "apps" like you mention. It works poorly for smaller tools: what if you want to have your editor and a console side-by-side, and still view a chat window below that.

And of course you can do all that stuff with regular window UIs too, so that isn't really the essence of a tiling window manager either. As I see it, the real thing that distinguishes tiled environments isn't the "tiling" at all, it's the keyboard-first navigation UI that the tiling enables. And even though I don't actually use these things (I've tried now and again), that's something I see a lot of value in.
I currently use xmonad, along with the gnome top-bar to get applets, network configuration, etc. I have found this the easiest way to move into tiling window managers.

It still annoys that tiling window managers all seem designed to be hard to use to configure, almost as a matter of principle. I see no reason that a tiling window manager can't still be easy to use (for example, I use the mouse as much with xmonad as I can, and would like to be able to use it more).
The reason we did that type of animation there was to go through the four types of widget categories we cover (video, audio, images and utilities). Do you think it makes more sense to just keep widgets instead of animate to it?

When trying to get popular opinion for, say, an election -- sure.

However, there was one fire over 100 million miles. The problem isn't the 100 million, it's the 1 fire. This wasn't a controlled experiment, either -- they just stopped the clock as soon as the first fire happened, and multiplied. A week ago, they could have said "You have exactly a 0% chance of your Tesla catching on fire" and have been right by this logic.

To think of it another way -- let's say you get lucky and get a hole-in-one your 10th time golfing. Does that mean you'll have 10 hole-in-ones if you golf 100 times? Doubtful.

EDIT: Also, don't forget that Elon is mixing numbers. There's no fire if someone doesn't run over something. All these numbers show is that the average driver is more likely to run over something. Of course Tesla drivers run over fewer things -- there are no 16 year old kids texting while driving a Tesla... yet.

I often see polls of 1K Americans and extrapolating out from there. An example: http://www.webpronews.com/americans-think-cloud-computing-co...

Of course, the refrain I often hear is that as long as you pick the RIGHT 1,000 Americans, it's as good as polling all 319 million.
I'm more glad that they didn't do it the other way around - considering how confident the NSA is about being able to keep finding new vulnerabilities in Firefox.

I think Facebook proves definitively that the layman doesn't care about "trustworthiness of the internet".
Being able to assume the #ifdef for features go one direction can have some benefit in reasoning about the code it relates to. In other words, there may be benefits to keeping the windows features a superset of the linux features, most likely in preventing stupid programmer errors.
Not trolling, you're assuming that all those words are used in a derogatory manner and discarding the actual content of the music so you can "defend" women. You're a pathetic white knight.
I really like twitch.tv and have spent hours watching it. But for reasons I don't want to go into, I'm forced to use a very outdated browser. And yet they managed to give me a really good UX over at twitch.tv.

Until recently, that is. Unfortunately, they changed their interface recently and as an effect my obsolete browser can't render some of their content anymore. It's especially sad for me, not only because I'd still really like to be able to watch twitch.tv, but also because it all used to work fine until recently AND the sites in question do not contain anything magically: it's simply that people's profile sites don't work anymore. But these pages contain the lists of videos people uploaded and without these lists, there's nothing to watch :-(

Oh, well. Of course the solution is simple: upgrade. But as I said above, it's currently not an option for me. So all that's left for me to do is cry.

And write overly dramatic posts to HN, of course.
An article about window managers with no screenshots?
Thanks for the tagline. We'll think it through and optimise the copy.
I think a lot of that depends on exactly who's being targeted, and for what reasons. Those revelations haven't made it out yet. The only information we have is the NSA director answering "Not intentionally, no" when asked if the NSA ever spied on American citizens, along with Snowden's allegations that there are no checks and balances if an employee of the NSA believed that they did, and Russ Tice's claim that the NSA spied on Obama.

It's often forgotten that there were many people in Nazi Germany or Stalinist Russia or Communist China or North Korea that believe those countries are completely justified in their actions as well. The reason they are widely reviled is because they lost: people outside of their culture came in, beat them down either economically or militarily, and said "That's not okay what you do to your own citizens."

If I look at the facts of what the Nazis did in the 1930s (before the gas chambers and concentration camps), it was that they turned a large portion of their state security apparatus inward and devoted it to controlling a portion of their population that the ruling class deemed undesirable. I don't know whether the same thing goes on at the NSA; I hope it doesn't. I do know that there should be checks & balances to make sure that it doesn't, because it can become an awfully slippery slope.
Sure, I was responding to the scary emphasized word.
What I like about Docker is that if I have a production server build based on Centos 6.4 and use Docker to install tools x, y and z, then I can easily and quickly build a VM on my desktop with Virtualbox, install the base Centos 6.4, and run the Docker builds for tools x, y, and z. At that point I have a dev environment that is as close as you can reasonably get to the production server. This means that there will be fewer integration issues in QA and fewer release issues down the road. That is what Docker buys you. Anyone who has worked with Solaris containers will argue that there is fundamentally no difference, and they would be right. In addition, you could skip Docker and just use build scripts written in bash and get the same results, and that is also true. Docker is a small incremental improvement over these earlier solutions, but what matters is not size, but that it does improve the situation. The Dockerfile is cleaner and clearer than a bash script. The registry is already built for you https://github.com/dotcloud/docker-registry and the learning curve for new people is much reduced http://docs.docker.io/en/latest/

These are worthwhile improvements.
I dont unerstand. So the right way to form a standard is to follow the biggest corporation and implement their formats rather then create fair chances for everyone, is that it?
It's counterintuitive, but the sample size needed for a good measurement doesn't much depend on the size of the overall population. What matters is getting a properly random sample. This is where pollsters fall down, because their "random" sample tends to be heavily biased toward the sort of person who has a landline telephone and doesn't hang up on pollsters.

Polling 10,000 Americans would be vast overkill, in any case.

I see it as any big new service out there. In the beginning there is going to be a spike in user interest. I'm guessing a large number of people using the site right now are doing it just out of interest (due to news reports about it). People browsing the site may have no intentions of actually paying for healthcare through the system, they just want to poke around and see what it has to offer.
I'm not familiar with notion or ion3, but I've used all of the other tilling managers listed. I really like AwesomeWM as a starting point because it comes sanely configured, and does not rely on haskell like Xmonad. Awesome is configured via Lua scripts, Lua might not be the most popular language but it's easier to pick up than Haskell and has a smaller dependence base.

Besides notion/ion3, which I am not familiar with, all these tilling managers are automatic. You select a layout directive like

- place all windows horizontally,

- place all windows in a grid,

- place one window filling 2/3rd the screen and the rest stacked in the remaining 1/3rd

There are other tilling wm's like i3, wmii, bspwm, and herbstluftwm which are manual tilling managers. i3 and wmii are probably the best ones to start with, but herbstluftwm is my favorite.

With manual tillers you typically split the workspace into multiple frames and windows are automatically arranged in those frames.

Here is an impressive gif of bspwm, a manual tilling window manager [0], and here is the reddit thread where the creater talks about his configurations [1]

> I would only point that 25 tons of force, isn't really a lot - I mean, the small jack that you use to lift your car can be a 5 or 6 ton device.

It's not clear to me why you'd say it's not a lot of force while making the comparison to a jack. Take a jack and use it under the wrong spot on a vehicle and you might get a pretty painful display of vehicle penetration, which is what we're really talking about here.
That depends on the population variance.

Are you planning on running this chromebook normally, or in developer mode (perhaps installing crouton or similar)?
Yeah much like a lot of substances it's only explosive in vapor form. I was thinking the top part of a gas tank, some hypothetical, but not likely, scenario. It seems that the danger from both the Lithium battery and a gas tank are about the same. If the car catches fire it will be because of some freak accident.

Although, there was the Pinto, which was just poor design: https://www.youtube.com/watch?v=qZDVqhWGILA
To ensure the Bug hit its target, a mechanical system was devised that would track the aircraft's distance flown. Before takeoff technicians determined the distance to be traveled relative to the air, taking into account wind speed and direction along the flight path. This was used to calculate the total number of engine revolutions needed for the Bug to reach its destination. When a total revolution counter reached this value a cam dropped down which shut off the engine and retracted the bolts attaching the wings, which fell off. The Bug began a ballistic trajectory into the target; the impact detonated the payload of 82 kilograms (180 lb) of explosives.
Do they really? My only interaction with pollsters has been either having them call me or solicit me on the street, and both approaches have a tremendous inherent bias. As far as I know, this is how the big national agencies do things.

Price of goods, especially digital goods, aren't based the cost of those goods. You don't expect to pay less for a low-budget indie film than a 300 million dollar blockbuster.

The price of something is instead based exclusively on willingness to pay for it. The market has proven that people are willing to pay more for digital goods that they own and can consume over and over over digital goods that they have a short-term access to.

It is important to realize that all useful comparisons to the Holocaust will be made against situations that are not as dire as the Holocaust.

If there is a situation as dire as the Holocaust, then rhetoric about things being as bad as the Holocaust is no longer useful. Useful points made in a situation that horrifically dire are made with machine guns and bombs, not rhetoric. The proper time for rhetoric is well before the situation ever evolves that far.

We should therefore consider carefully whether a comparison to the Holocaust is out of line or not. Blanket judgement about such comparisons (such as the standard interpretation of "Godwin's Law") are not useful.

i'm no expert, but i believe machine learning / classification algorithms can help you on this. you just need to train the algorithms on what you want to find.

'finding' objects means feeding the algorithms a series of 'features' that you extract from video and normalize into data structures - color, corners, edges, velocities, relative distances, etc, which are then fed into the algorithms to produce a classification or a probability.

analyze every Nth frame and try to classify found objects. if a known object is found, do something.
Totally agree, bonemachine!
The "web" has existed in a mature form for over 2 decades.

The web's success has been extraordinary in the same terms of any monumental human achievement -- the discovery of anti-biotics, the moon landing, the Magna Carta.

Why would we cripple that set of features just to make a tiny group of people happy (relative to the world's population, the copyright "special interest" cartel is indeed microscopic.)

And I thought web sites screwing up keyboard shortcuts was annoying..
