Don't you know how the financial system works? Banks make currency. With Bitcoin, they haven't figured out how to do the same. Their empire is in danger. His argument is predicated on the false assertion that currency has to be legally recognized; it doesn't. It only has to be accepted by those who trade with it. Not only is he bashing Bitcoin, but he is bashing all of cryptocurrency. What an idiot he is. The real fraud is perpetrated upon us by banks who lend dollars without holding hold an equal value of gold or silver. In past centuries, this was punishable as a felony by death.
Yeah I'm sure techcrunch has nothing to do with this...

Windows Hello is pretty good for fixed or semi-fixed devices (e.g. Surfaces, Laptops, desktops) but really not great for mobile.

Hats/sunglasses/rain/lighting all cause problems for mobile devices and face recognition.

It'll be interesting to see if/how Apple overcome those problems
"Face data"
I think one reason it seems so strange is that it is sort of a mis-characterization/failure of communication that easily happens in politics. There is nothing wrong with unions in principle, but once someone has written into law exactly what a union is, then the possibility for mistakes and unintended negative consequences exist. When the UAW were fighting for better wages and conditions in bygone days, I don't think many at that time thought the same laws would contribute to GM declaring bankruptcy and needing to be bailed out by all 300+ million Americans, who were never involved in any of the bad decisions made.

And reasonable people can quibble about who shoulders more of the blame, but one can't deny that American labor costs were significantly higher than foreign competition and were largely impossible to adjust.

Unions today need better leaders, who realize that the future is in collaborating across national borders with their brethren at all global corporations. The United States simply cannot enforce its own labor laws in China or any other proud nation. Workers created unions themselves, they did not need government to do it for them...which is good because neither the US nor Russia or China rules the whole world.
Frama-C lets you prove all sorts of useful properties about C code, including memory correctness. (Actually writing the proofs is a lot of work though.)

Cohesion is something that can't be mimicked; you have to actually build out the entire ecosystem of apps with a consistent look and feel. That's a monumental task.
> Hey guys! What’s up? It’s Julie.

I've really grown to hate this intro, plus the whole "bouncy" style of pronunciation. To me, it sounds a lot like "I'm trying too hard to get attention", like that of a 2 year old repeating "dad. dad. DAD."
Indeed especially when driving that millions of us shouldn't be doing but do anyway. Touch ID made it so easy to unlock ... can't imagine Face ID being a better in this scenario.
But then you have to adjust your grip, at least for me when I unlock my iphone I am using a different grip then when I try to click an icon on a homescreen, so if I would use face ID - it will save me some time for adjusting grip, at least that's what I imagine, of course nobody have tries face ID yet.
This stood out to me also. I understand why they didn't do so - randomizing exercise for 8,000 people is all but impossible. (Unreliable for "do more", potentially unethical for "do less"). But it's pretty worrying because there are a stack of possible shared causes between mortality and activity.

Everything from obesity (cause of inactivity and shared causes with inactivity) to rarer mortality risks like cancer would simultaneously act to create this result even with no causative linkage.

It seems like a new version of that infamous NEJM study showing that low and healthy weights have especially high mortality - because terminally ill patients tend to lose a lot of weight.

Is it illegal for a seller to price something in the U.S. in bitcoin (or a some other form of exchange) and not dollars?

If cigarettes became a more attractive medium of exchange, is it illegal to use that medium between two private, consenting parties?

I don't think you'll see this be the default experience across Apple devices for quite some time. I don't think even the iPad Pro will have this edge-to-edge screen for at least a couple years – the home button is not dead.
Why why why why why?

What is the point in this? Seriously. Please can someone enlighten me. Atom was bad enough with all of the other text editors are out there and not written in JS, but now you can't even say it's just a text editor. Facebook and the other contributors clearly have too much spare time on their hands.

Very cool to see companies mapped out.

Slight nitpick - I really wish click to drag panning and mousewheel/pinch zooming was supported on the map. Navigating the map was a bit of a chore - mostly for smaller geographically sized countries.
Carolinian here. I say I85 (interstate) or 76 for state roads, but never "the 76".
500ms is a LOOONG time. That's about how long my S8 needs, and I always question whether it works this time. 100ms or so would be great.
I'm particularly interested in metastudies about fields like sociology which are dominated by people of one particular political ideology--I'm curious about the degree to which this homogeneity affects the quality of the work that the field outputs. I don't have a theory, but I am curious about what size grain of salt I should take when interpreting a particular finding.
Is it a Facebook project though? The announcement says in collaboration with Facebook. That's an unusual definition of the word collaborate.
Releasing any kind of machine-assisted driving without a near infallible "don't hit objects in front of the vehicle" function is simply irresponsible.

Yes. There are four videos of Tesla cars crashing into objects which partly protruded into a lane. Three vehicles, one construction barrier [1], all on the left side. One fatal.[2] Relying on the Mobileye vision system, which is "recognize car/pedestrian, compute range to target" for anti-collision was grossly negligent of Tesla. Tesla has a radar, but it can't be very good if this is happening. Even the old Eaton VORAD radar, which we used on our 2005 DARPA Grand Challenge vehicle, would have avoided that.

This is the simplest and most important part of automatic driving, and Tesla botched it.

But the reason you unlock it is to look at the information on your phone, so it's not like you are using touch id without looking at your phone after that, no?
Bitcoin (and other cryptos) do have real uses for which there is real demand. My worry is that the current price has substantially outpaced the support that those uses offer.

Let's go over some of the things that make up bitcoin's price:

-You can make legal retail transactions -- a very small portion of transfers, but legitimate. This is a 'regular money' use.

-Make large 'wire' transfers for less than it would cost through your bank. Totally legitimate and valuable in my opinion. This is a 'Regular money' use.

-There are future expectations of bitcoin expanding the above two points. Supports the 'regular money' points above.

-You can use bitcoin to (illegally) move money out of countries like China, which is now being cracked down on. This is a black market money / money laundering use.

-Use as a speculation instrument. Valuable in a way, but only bullish on net because it is supported by the above services. This can be done with 'regular money', but speculative financial instruments are primarily assets and not regular money.

There are many others, but those are the big ones I know about. The issue is that it appears the price is 80%+ speculation, 15% capital flight, and maybe only 5% of the demand for the asset is based on the traditional 'regular money' uses... What this means is that once the speculative support moves from net positive, to net negative (meaning, once Bitcoin gets a widespread reputation as being a dog) things start to go downhill hard.

Of course my estimates above are very loose, and in the future the expansion of bitcoin into a far larger mainstream uses case could overpower all of them, but either my estimates above need to be off (and they may be) or we need to see large scale adoption of bitcoin for legitimate uses at some point (also a maybe).
It can be interpreted that way, but usually that just means the work cannot be dual submitted for consideration or have appeared as a preprint without explicit permission.
Shocking to read. But what really shocks me is the amount of arrests mentioned for possession of heroin or syringes.

When will the US (and the rest of the world) finally learn that locking users up just perpetuates the problem - you won't get a job with a criminal record, same for housing. All this arresting does is fill the coffers of (private) jails and creates needless suffering.

Also, why do people keep calling the cops on relatives and friends who OD? That just makes the problem worse. In fact, it should be made illegal to arrest anyone when emergency services are called to an OD, and this must be publically announced. People rather let other people die than save their lives because they're afraid of jail.

> She’s part of a protest against Butler County Sheriff Rick Jones, who won’t let his deputies carry Narcan. He's the only sheriff in southwest Ohio whose department doesn't use it. Two doses of Narcan cost about $75.

And, what kind of person is this moron? He should be in jail for willfully preventing deaths!

> “Either she got a new dealer, or her dealer hosed her,” a paramedic says.

Yet another case for why it 'd be really necessary that the state provides drugs like heroin, with proper quality control. So many deaths and near-deaths that could be avoided.
> I think your point is void here, because in both of the cases I mentioned, the car was clearly worse than a human.

But separate cases are not really interesting when comparing accident rates. Think of a more extreme made up scenario:

You can either drive yourself and be part of the "1.25 deaths per 100 million vehicle miles" statistic (US), or use an automated car which causes 0.25 deaths - but it spontaneously explodes in that case. No other car would just explode randomly while you're driving it. (It's clearly worse in that way)

Do you want to drive yourself, or take the automated one?
Dynamicland – incubating a humane dynamic medium
I do hope Apple have got this facial recognition stuff right, but personally I'm skeptical that it'll be better than TouchID.

For me, from reading previously leaks, this feels like a compromise where design (we want a phone that's all screen) wins out over usuability (TouchID is great for usuable security)
That is 'average sedentary period', so you can still sit for 30 minutes occasionally. It would pretty much take a standing desk and constant focus on activity to get <10, though.
Hmm, definitely hop on the entire CLI, you won't regret it.

As far as live reload goes, it definitely is faster than 1 minute, are you connected via USB? For live reload I would stay connected via USB and then obviously you need to be on the same Wi-Fi, (For iOS, I've only used the simulator for development, but we test on a real iPhone all the time)

What kind of issues are you having with the menu? The only bugs that I've found had to do with animations, I had to use CSS animations as opposed to the Angular way of doing animations for iOS.

Other than that though, I've found the iOS to be the most stable version of the application, even though I developed it almost exclusively on Android (with some spurts on iOS to ensure everything worked).

As for the router, yeah I see what you're saying, our app is pretty straight forward as far as navigation goes.

The grid, I agree, it's annoying, it's like they threw bootstrap grid system and flexbox into one, and it's a bit strange.
I don't know exactly. Surely Paypal helped.
Ask HN: Open Source Video Hosting Platforms?
I understand this is a loaded question. Video hosting is a big business and companies like vimeo, wistia etc. are thriving and it is a tough problem to solve (bandwidth, network, performance, cost etc) .

However, I wonder if there is any Open Source projects that tackle the beast of video hosting. It could focus on components such as:

- Storage

- Transcoding

- Performance (CDN delivery)

- Experience (Players such as videojs etc)

Each of these are projects by themselves. Anyone know any specific projects that target some or ideally ALL of these components ? I am specially interested in the harder ones like transcoding and CDN.
Thank you. This is incredible.
Lol, just as it fails in the live onstage demo ...
For people using Apple Pay on the Oyster network in London, the speed of face recognition is absolutely gonna make or break this.
Honestly, the fake Nobel prize for economics really diminishes the credibility of the Nobel prizes and science in general. I like economics, have studied it and follow it, but it does not deserve to be placed alongside the hard sciences where actual irrefutable progress is occuring.
Face data is never sent to server, stored on device.
love this concept, could even find myself using it for personal use if it had other popular web subscriptions, ie: netflix, hulu, feedly, spotify, etc
I turned off the stream because I needed to get back to work. Did they say anything about security for FaceID? Such as where the data about your face is stored. Or what about just holding up a photo of someone?
Face ID just failed in the on-stage demo. Oops :(.
Take this example of poor people: A person earning 10k/year and a person earning 40k/year both need basically the same things: Water, shelter, food.

A person earning 40k per year isn't MUCH better off than the other. They are both broke, and only have money for the necessities. But if we only tax consumption. The person earning 10k will end up spending a larger percentage of their income in taxes than their counter part.

Now lets throw into the mix, me. I make a healthy 6 figure salary. Lets say I also only pay for what I use, and as a penny-pincher, I only get cheap housing, buy bread and cheese for my food, and tap water. I'm now paying the same taxes as the person earning an order of magnitude less than me.
Lol the first Face ID demo had some issues
I installed Fedora 26 as the only OS on my laptop and I am very impressed. I don't miss Windows at all. I have played with Ubuntu in the past but Fedora blows that out of the water.
Did the FaceID just fail on stage for Craig Federighi?
Agreed. If it's fast enough to unlock by the time my face is facing the iPhone, then I'm not losing any productivity there.

e: But watching the keynote, it's definitely doesn't seem that fast...
The difference is that often sales commissions have no (or much higher) upper limit. That is, if you are skilled enough (and lucky enough, for sure, since there are certainly many factors outside of the salespersons control), then they can potentially make a large commission. On the other hand, a salaried engineer has a hard upper limit (their salary + any bonuses that may exist) which can only be raised through a promotion or renegotiation.

A problem for me is that there's little incentive to work b tons what my contract stipulates and what my manager feels is acceptable productivity (and whatever I need to get bonuses, if I get bonuses at all), because I get the same compensation (in terms of money or time off or whatever -- I don't get to leave early if I finish my work early: I move on to the next task instead) no matter how hard I work or productive I am. So why would I wear myself down by working harder if I can be less stressed and work less hard for the exact same compensation?

At least a commission-based role puts some of this into my hands. If I feel I can make more sales by working harder/longer/faster/smarter, I can get paid more.
I program a lot in C, F# and Python. I mostly use visual studio code (electron app similar to Atom, but better). It's great if you're using languages which don't come in one IDE, or where you need to pay for the IDE (F#).
I approve of Face ID more than Windows Hello, but I'm not convinced that neural networks are ready for security prime-time. Have we solved adversarial attacks yet? Were any of the masks they used in training painted with adversarial patterns?

(The tech is cool, though. Actually amazing, that it fits on a phone.)
I can barely get the damn thing to work reliably when I'm watching carefully where my thumb goes. I salute you.
I may be wrong, but I remember reading something that most humans can't notice any lag below 200ms.
Large parts of psychology research of the past couple of decades turned out to be crap. ("non-reproducible" in scientific terms, but "crap" is close enough.)

Kahneman has defended much of this research in the past. But at least he's smart enough to recognize his mistakes, which cannot be said about many of his colleagues.
Nice, thanks for posting. I'm using Gitlab Pages right now, and it's fine, but having my deploy process depend on Git is kind of weird. Plus Gitlab isn't really a web host: they're a Git host. I'll definitely check this out soon.
It was said Face ID is one in a million so that means ~7500 people can unlock my phone..
If evil twins are a weak point how came facemasks don't work?
Yeah, seriously; I think it all really comes down to willingness/ability to learn. My grandfather came to computers very late in life and has since managed to pick up every Windows iteration since 95, Ubuntu, ChromeOS, and OS X with aplomb. He loves his iPad best, though (mainly for Skype and FaceTime). My mother, in the meanwhile, struggles to use Word.
Another reason to keep using my iphone-5s. New phones are way too big, and I love the home button. If I was forced to upgrade I'd get the iphone 7 se (the mini one)
So why did the developers of a text editor decide on a web browser stack for their project?

Yes, I know that the answer is "electron". They picked the wrong tool for the job.
Probably not a good sign that FaceID failed on stage for Craig on his first try (had to use a passcode to log in) during the demo.
what if it is dark? this guy even had issues just using it on stage
You got all of that from a press event? reallY?
This is also true for finance which is heavily dependent on Excel. Very few people want to audit and verify a model given the monstrosity that some spreadsheets turn into over time.
Someone can drug me and hold the phone in front of my unconscious face to access all my data?
Don't know about Face ID. Microsoft Windows Hello solved it couple of yrs ago.
Should we judge performance in every scenario distinctly, or in aggregate?

That is, if the risks of one edge case goes up while the car performs far better in the vast majority of situations, is the car worse than a human?
I fail to see how this Face ID will work in a North Dakota winter or on the ski slope.

// And they had a demo failure on their new unlock and swipe up for home.
I think accents themselves will become a relic of the past, given the prevalence of mass media and the internet. Millennials will probably be the last broad generation to have any hint of an accent.
it just didn't work twice live on stage.
As a non-native speaker, that's how I would say it because that's how it would be said in my native language.

If someone told me "I took 5" I'd expect them to be talking about some kind of quantity and wait for them to finish the sentence.

Can a non-American native speaker maybe chime in how this works in other dialects? I'm wondering whether it's Californians who are the odd ones out or whether it's just uncommon in the US.
JP Morgan's work on blockchains seems pretty far divorced from crypto-currencies.

Much of the work I've seen has been more ledger/private chain oriented.
Banana Ketchup
Because a lot of this is transient signals that are crap? One of our robots back in '06 would panic stop every 30 seconds or so whenever there was a dust cloud (this was an army off road formation project, so dust was a fact of life for all the followers) because occasionally there would be enough random scatter returns from the dust to convince the MMWR that there was a wall in front of it. Panic stopping from highway speeds every time your MMWR detected a flyer floating in the breeze near some dust seems like it would be pretty dangerous- especially for the cars behind you that are also traveling at highway speeds. And LADAR doesn't have the range to be useful at highway speeds (from memory, the ratio of range to safe braking distances means you can't get above 25-30kmh with LADAR being useful for you).

As for whether having shared autonomy at highway speeds is a good idea, that's a really good question that I hope Tesla is asking itself right now. But if you are trying to do that, cameras pretty much have to be your primary source of truth.
Why the downvote? All of these system have been proved easy to trick. Do you really think depth perception is a real hurdle? 3d printers do exist. It is based on IR detection of projected points, so you might even be able to fake it with a specially prepared photo (for example with holes for the ir points) and an ir source behind it.
They just showed a full screen video and the black bar was blocking part of the video. This looks really bad while demoing with views animated in real time.
Ok, the guy demoing the iPhone X just had to switch to the backup phone because the Face ID on the first one didn't work quite smoothly.
iPhone is ok, despite being generic. iPad on the other hand... no number, 2, the new, 4, 1, 2, no number. It is only logical :)
Anyone else here remember LindowsOS (later changed its name to Linspire)?

In the early 2000's (around the time of the article), they were trying to get point and click simplicity for installing software (which even back then was abundant in Linux). I remember a few others distros, like Mandriva (Mandrake at the time) had graphical package managers. There were others.

To anyone who's curious and feels like giving old Linux distros a try, https://old-linux.com/ is a good resource. Unfortunately I can't find any mirrors of repos with packages that go back to 1998 and early 2000's.
Initial demo for Face ID failed -- Obviously less than ideal when trying to convince your audience that "it just works".
Just auth before you get to the turnstile.
or plastic surgery for that matter?
And it failed in the demo...
oh like the iphone 4 antenna?
Why does an init system do DNS lookup?

And in such a breaking way?
I wonder how well Face ID works with dark skinned people. Dead serious. Historically facial recognition has had a tough time with dark skinned folks. The inclusion of an IR camera should mitigate, if not solve this, but I'm curious to the accuracy in practice.
Virginia scraps touch-screen voting machines
Looked like it was reasonably quick in the demo.
I have that book, though I haven't looked at it in years. I found it intractable then. I've been using clojure in the interim and feel like I've learned quite a bit, so maybe I should go back and look again.
