Thats an awesome read!!!!!

Will a passenger from a passenger airline survive if falling from 15,000 feet?
Do people publish work based on this thing?

I'm sure lots of people do. We're a commercial company selling consultancy service around this software (technically around some inhouse tools built on top of this software), among many other things.

Is correctness somehow assured provided it doesn't crash?

On the whole well tested PDE solvers either crash, give answers that are off by several orders of magnitude, or give a correct answer. (If the answer they give is relevant to what you're trying to model is left as an exercise to the reader)

We're reasonably sure that, if the calculations converge, the solution provided is a correct numeric approximation (within the error bounds given) of the PDEs we're claiming to solve. We also believe that the PDEs we're using provide a reasonable balance between modeling what we claim we're modelling and our computation running in a reasonable amount of time.
It's certainly not aesthetically pleasing, although there is some mileage in that department with printed duct tapes, but it works which is the main thing. To be honest with careful routing it's only taped down in one place in a corner. You wouldn't know there were any cables running around unless you look very carefully.
Back and yet gone too. HN effect in full effect.
Someone pointed out low-pass filters to you, but that's not the entire story. Built-in speakers in phones and laptops generally don't have a naturally extended frequency response.

A while ago, I made audio measurements of the built-in speakers on the iPhone 7 Plus - https://imgur.com/gallery/DRbu5

The iPhone's extension is not entirely atypical of such devices, and leaves you with a reliable passband of 500 Hz to 10 kHz - above and below those frequencies, you're getting too much noise.

If you're airgapping with audio cables, you'll have a reliable passband of 20 - 20 000 Hz or thereabouts, with some caveats for built-in audio on devices such as a Raspberry Pi that fizzle out at 15 kHz.

As noted by brian-armstrong's comment, you'll only get reliable near-ultrasonic airgapping over a wired connection.
Worldbuilding Monthly
Because they built a car that people lust after. Breaking it down:

Exciting, classy exterior shape
Retracting door handles
Giant touch screen
World class consumer software UI
Regular OTA updates
Ludicrous mode
Auto pilot

Each of these is individually incremental-- the sum is amazing... just like the iPod and iPhone: there were many MP3 players already in the market and my Windows mobile 5 smart phone worked pretty well - but nobody lusted after those things.
How to Ask for a Raise in Customer Support
Alternatively: accept the value of Messenger and access it directly via https://www.messenger.com or the Messenger app.

I will never be able to understand these articles as ALL (with some exceptions) my friends are on facebook, and it is the only way I have to keep touch with all of them. This is a huge problem for people like me who travel a lot and have no other ways of getting in touch with someone.
Etymologically, Quality Control implies some sort of feedback. Quality Assurance merely implies a filter at the end of some process.
Some closer friends might, but several of these people doesn't have my phone number or email. I participate in several groups and people often write "does someone want to do something today?" etc.

To message every single one every time and ask would be too much of a task. Of course you could create a mailinglist but then you'd have to convince everyone to use that instead which I know would be impossible.

But to answer your question, yes.
The major players tend not to bounce emails. They accept all mail at the edge, and then blackhole it once it's actually looked at by the backend.
I'd also suggest Genesis [0]. Almost S-class level in terms of features and comfort, with easily half the price. It's a luxury brand of Hyundai, so as a fan of brands like Mercedes I was skeptical at first, but damn is it a good car.

It's an unusual method. There is now a standard method for this, which is printed on the SOLAS (Safety Of Lifes At Sea) cards we sailors are required to carry, although the direction ones are not on all versions of the card I've seen. Here's one that has them (section "Air to Surface Direction Signals): http://www.marinelite.gr/images/detailed/1/221518a.jpg

For a vulnerability of this magnitude, it's not unusual for a responsible disclosure to have a five month review window.

e.g. Dan Kaminsky's discovery of DNS cache poisoning had a 5 month responsible disclosure embargo.
Not really. As far as I can tell, the attack basically requires spoofed MACs anyway because the keys are derived in part from the MACs, so whitelisting won't get you much benefit if any at all.
>What is a "unit of human work"

Money, obviously?

> Why are people paid differently for the same work?

Do you want me to do a crash course on history of economics in a HN comment?
Nope,

This will fool your client (eg: your phone) to connect to it, before it reaches your access point, then forward packets to your AP (basic man in the middle).

On the other hand, I am wondering if it manages to correctly forward packages back to the AP if that has MAC filtering on...
At this point I'd be more interested in a "I re-opened a facebook account". Which I'm sure we'll get down the line.
At its worst, this attack reduces a protected network to an open wifi, yes.

The risk is that you may do things on a protected network assuming it really is protected - this is more of a thing for organisations rather than consumers, for example organisations might have unprotected services accessible over their office wifi.
Maybe this is the only reason why new js ui frameworks are created- to run away from the mess and unintentionally find yourself in even bigger pile of junk
> Instead of trusting a mostly anonymous group of people that stand to gain from abusing that trust and have done so in the past without punishment, crypto replaces that trust with user-controlled software and verifiable algorithms.

This used to be true in the beginning of Bitcoin (when CPU mining on your desktop was OK) but it's not true anymore. The integrity of the ledger is guaranteed by the miners, and now the miners are not individuals but companies with ASIC farms. You have basically no guaranties that these companies aren't going to plot against you to tamper with the ledger. Of course at the moment it would be a terrible idea because it would destroy the confidence in Bitcoin (and that would destroy them) but it's not that different from what stops a central banker to print a huge amount of money.
Thanks again for your long reply.

I'm just a suspicious guy, and when I wrote an ecommerce cart system for one customer, and then move on to the next customer, I never take source with me. Did I benefit from designing and thinking through the first very similar system? Yes. Did I take things with me? No. Do I adhere to best practices that were developed in projects in the new company? Yes. Do I reuse code? No.

So - again - from my suspicious point of view, declaring we - hundereds of engineers and the company - took no knowledge and expertise except the engines from the CX–HLS program makes me suspicious.

AND as a CEO I would probably not be happy with engineers that do not use knowledge from other inhouse projects in a highly competitive market.

But I'm no primary source ;-)
The idea that having yet another idiot/liar/narcissus as president (as has been done many times in the past) is about to bring the end of the world.
"This sentence sounds like preaching."
Yes, you are right, I was wondering whether to edit that sentence to sound less confident. :) I have no evidence, and I am not an expert on this. I just think that if a currency is a utility currency, actually used by merchants and everyday users globally across a wide range of industries, countries and people, it has a huge market cap (it is the dominant currency of the world): I just don't see what could cause big fluctuations in its 'price'. (When you start to be the dominant currency 'price' becomes an interesting concept, because the 'relative to what?' aspect starts to be very significant.)
It's a loss, even if you use openbsd. If you break the embargo, you won't be notified in advance anymore. Basically, you get an advantage once but will get several losses for a very long time. Overall it's bad, even for OpenBSD users.
Yes, but the underlying fact remains, something is different between original Apple repairs and non-Apple repairs, and this can somehow be detected by the software.

How exactly Apple will leverage on this may (or may not) be relevant in the end.

To give you a side example, a few years ago there was someone making and selling USB to Serial cables using a "fake" FTDI chip.

The manufacturer (I believe rightly) issued (silently, and this is not-so-right IMHO) new drivers that could recognize the "real" chip against the "fake" one (and refuse to connect if the "fake" was detected or inject garbage in the communicaton or even "brick" the device).

A couple references:

https://hackaday.com/2014/10/22/watch-that-windows-update-ft...

https://hackaday.com/2016/02/01/ftdi-drivers-break-fake-chip...

Still a lot of people that had bought the cable/converter (without any way to know if it was an original or a fake one) in good faith and had it working just fine, suddenly on a new machine/after having downloaded the new updated driver found themselves with a non-working setup.

This created at the time a lot of issues, until some older drivers were found (or new "original" devices were procured).

Of course it was just a "specialized" little device, usually in the hand of technically savvy people that - one way or the other - could solve the problem, IF Apple decides to do something similar with "unofficial" spares and repairs the impact may well be much bigger.
They agreed, but now they regret the decision and wouldn't make it again. To prevent themselves from doing so, they will not speak with OpenBSD until later in the process.
Just ignore the moon ninjas episode.
Yeah, because "human connections" can only be achieved on a web platform, with people you merely chat with on a casual BS basis for casual BS topics, and consider "friends" besides seldom meeting or having much in common with most of them.
One thing you can bet on is that virtually every carmaker is over-hyping their technology. Expect "Level 5" tech to be more like Level 4, "Level 4" to be more like Level 3, and so on.

I don't even know how they can even claim Level 5 (looking at you Nvidia) when their systems don't involve real-time training, but just do inferencing. I'm talking machine learning training not "it's gathering data as it drives training". You know what that means - it means the cars's autonomous systems need to have been trained for the roads on which they are driving or at least for those conditions ahead of time, somewhere in the cloud.

But Level 5 is supposed to work on ANY ROAD ANY TIME. I doubt they have already trained their systems for ANY ROAD ANY TIME and anywhere in the world. That seems very unlikely to me. In other words, Nvidia, and Tesla, and whoever else is promising Level 5 autonomy is lying to you.

And because of this stupidity and greed, the government will probably have to come up with Level 6 and Level 7 in the future, to designate to Level 7 what Level 5 should have been from the beginning. Think about how the US carriers started abusing the "4G" marketing in the early years. I very much expect the same to happen with self-driving cars, all for the sake of misleading marketing.

I also believe none of these players take software security that seriously. Some will at least implement the best practices, but won't go beyond that, most probably won't even do that (Google how stupid carmakers are being about remotely unlocking their doors over the internet for instance...). Unfortunately, this won't be noticed until maybe 7-10 years after millions of these cars are deployed. And then the hacks will start coming (including terrorist attacks using them).
I can't help but feel that if Facebook has such a huge negative influence on your life, the problem isn't Facebook but something deeper you need to resolve in yourself. If you're getting hopelessly addicted to Facebook or letting it make you feel bad, you're probably just going to replace it with something else until you fix the reason you let it impact you that way.

I use Facebook to keep up with friends and arrange events. It's a useful communication tool and I don't get caught up in it any more than that.
Yes! To me this is an area where rust could really shine. Embedded development in c is chalk full of headaches that rust has the right medication for: package mgmt, code reuse, safety. I would love to see more people building packages and focusing on making rust great for embedded development.
I just decreased my Facebook use to minimal.
Won't remove it because of possible FB identity theft.

You can do more and more with Facebook Account it's just just scary to lose control over my profile.
Ask HN: How can I find the top Show HN submissions of all time?
Correct me if I am wrong but basically the attack is against clients, not access points which means simply patching the AP will not do, one would have to patch all of the clients. And the AP patches that are now coming in are probably for client mode, so they fix a certain scenario when the AP is a client which is far from the common one?
Before Facebook, there was an entire genre of "friends reunited" stories, where people had lost contact with someone they used to be close to and recovered it after decades. That was back in the old pre-connection days where you could just lose someone's contact details, or they could move and if they didn't update you (or you were both moving) that was it forever.

Now things are very different. You never have to wonder what's happening to those people you knew at school, or wait for the reunion.
There's one article on Google News when searching for RSA:

While I can imagine that neural networks are useful in predicting rainfalls or precipitations, I don’t see how they are suitable for some tasks, such as the forecasting of typhoon paths. A neural network is basically a function interpolation device. To use it for prediction, the implicit assumption is that the function it approximates is somehow well behaved, but some weather systems are chaotic. Function interpolation doesn’t seem very useful in this regard.

From what I see from googling, cyclone tracks forecasting by neural network is definitely an active area of research, but apparently they aren’t practical yet. The lady you talked to were probably working on some chaotic systems like this.
> Many people have throwed away their cigarette packs, it's not a big deal, you just announce you're going to do it, get that one last cig with a friend then do it. Others never started to smoke. Life is fine without smoking, if you feel you want to stop smoking, do it. Footage at 11.

> Many people have stopped gambling, it's not a big deal, you just announce you're going to do it, get whatever money's left on the table then do it. Others never started gambling. Life is fine without gambling, if you feel you want to get out of gambling, do it. Footage at 11.

I am always shockingly impressed at the lack of empathy and open-mindedness some people or group thereof are reliably able to show, here failing to recognise that this mind trick minefield can have devastating effects and act at the very least as a dramatic catalyst in loss-of-balance situations. The underlying, untold, insulting judgement is basically "damn this guy is weak/an attention seeking whore".

I found the article articulated quite well the issues he faced, his reasons (which extend beyond Facebook's carefully engineered attention seeking madness) and both of his strategy and tactics to get out of the hole he found himself in (which extend beyond Facebook and social networks). Writing about one's problems help a lot in internally processing them. Making a public statement helps in committing oneself to improvement, and help others in a similar predicament to relate and hopefully even proceed to action.
This is the way it has always been. Do you think the SEC was just created because someone in government thought it was a good idea?
What's the word for pressuring a person until they make a decision they immediately regret?

Software is a means to an end. We can't discuss software without understanding what we need it for.

The ultimate goal is omniscience and omnipotence. If you had that, you wouldn't need software. Software should serve to eliminate the delta between "I want pizza" and "I have pizza".

Humans have physical limitations. They can't be everywhere at once. There's a limit to amount of information they can learn and process. They can't focus on multiple things at once. They need to offload most of these responsibilities to others (whether humans or machines).

Omniscience is the first thing we should tackle. We must capture, process, organize and store the world's knowledge. We can't continue having each company/service/app store knowledge in their own format on their own servers. We need to distribute knowledge in a standard format, that can be consumed and created by anyone. I believe the semantic web was on the right track, and we should push these ideas forward.

Once there's only one knowledge repository, it's trivial to program IoT devices to broadcast all their sensor data in that format.

Omnipotence starts with the formulation of intent. First, we observe the world for problems. Once we identify a problem, we pick an alternative reality that doesn't have that problem. Ultimately, intent is the communication of a future state of reality (ideality), and is represented and stored exactly like the knowledge mentioned previously.

At this point, we have a knowledge base full of data about the real and the ideal. The last step is to bridge that gap, and make the real become the ideal. For that, we need smart contracts, the union of multiple ideals. These contracts can involve other humans, or be automated by involving robots. Resources, whether humans or machines, are defined by the set of all futures they can make happen. For example, a Uber driver is defined by its ability to take you from a continuous set of location A to a continuous set of location B.

Before we rebuild the entire software stack from the ground up, we need to figure out how knowledge will be represented, how smart contracts will work, and what the interface will be like.

Tampering with the ledger is sufficiently difficult that it's not a real risk in cryptocurrency. There are plenty of other real risks that are far more relevant.

I don't remember Java going down this path. Also the Julia license is very permissive which undermines the commercial case for, and removes the community imperative for alternate implementations.
You are correct but if the trend is moving from a heavily monetised property to one that isn't....?
I continue to be astonished there is no support for passwordless encryption (open hotspots with no password needed to connect, but with some sort of automatically-negotiated encryption). Dropping encryption should not be required for a good user experience on open hotspots.
Are people that can't be bothered to mail you a letter really your friend? Facebook is an efficient form of communication that the vast majority of people use. I'd expect close friends to go out of their way to contact me but you have to accept that by not using Facebook you're going to miss out on things and creating an inconvenience for people. SMS and email aren't as efficient for arranging group events.
Ask HN: Why Is Siri So Awful?
Title says it all, but here's some more text anyway. Seems like the only things I can get Siri to do are set alarms and reminders, and search the web. Although even then the chances are it'll get it wrong and I'll just have to do it manually on screen.

Play podcast sometimes works, but I can't ask it to play a piece of music on Spotify.

I've given up asking questions, but you'd have thought that Apple must have a list of all the questions that have been asked over the years, in all the different formats, and they could chip away on making it work with the most common ones.

Instead, it seems like the whole product has gone nowhere since launch, which was a good 4 years ago I think.

The latest iOS release was supposed to improve things, but I see nothing of note. Aparently, Siri is now doing something with contacts and calendars, but this just seems like branding, in the same way that IBM's Jeopardy-winning Watson can now come up with new recipes.

Why can't Siri do more stuff? What even _can_ you reliably do with Siri?

I mean, what the hell?
I agree, and I say this as a woman.

I hear a lot about facebook but I almost never run into it though I feel like I am literally living inside internet. It amazes me how something I can literally not see any presence can have presumably such huge importance in the cyberworld. Google, I get it, twitter, I get it, facebook... nope. Looks like big inflated wind to me (or quite crafty salespersons).
True, they don't. However, this researcher has the authority to not notify the openbsd team in advance any more and he already announced that he'll keep his cards closer next time. What happens if sufficient researchers come to the same conclusion?

I don't think that's a fair comparison; I'm sure they had a plan for mass-scale production for model 3 from the start, the problem is if that plan/approach will work or not in a reasonable time.

The non-scaleable stuff was most likely done in parallel not to delay initial deliveries, they don't need to validate the product idea.

TIL. And yes, characteristics associated with Ethiopians apply:

Operation Solomon airlifted almost twice as many Ethiopian Jews to Israel as Operation Moses. The operation set a world record for single-flight passenger load on May 24, 1991, when an El Al 747 carried 1,122 passengers to Israel (1,087 passengers were registered, but dozens of children hid in their mothers' robes). "Planners expected to fill the aircraft with 760 passengers. Because the passengers were so light, many more were squeezed in." Five babies were born aboard the planes.
