It's not really supposed to be secure against fraud by card thieves. It's supposed to deter actual cardholders from falsely repudiating their own purchases. If you chargeback a purchase as unauthorized, the retailer should be able to produce the slip with your signature on it. Then you can be asked under oath or penalty of prosecution, whether or not it is your signature. It also provides protection against errors. If you are erroneously charged multiple times for one for one transaction, the retailer will only be able to produce a single signed slip. If you actually make multiple purchases in the same amount in a row, there would be multiple, signed slips with different timestamps and distinguishably different signaturs.

There's a fiction that the retailer should compare the signature on the card to the slip, reinforced by a few large retailers with policies of checking that the card is in fact signed, but this obviously doesn't happen.
Yes I know there are ways to technically work around their walled garden annoyances, but the principle is more important. The fundamental function of a web link from one page to another should not involve nagging to register or sign in for a service which boasts "free and always will be". I don't think most FB users and business pages are aware that their "public" posts and pages are now obscured by sign-up nag sliders.
It does seem to be a euphemism, one used to paint scammers in a better light. Remember, 10 years ago we were calling social engineering hackers scammers and con men.

> "Another study from the same NIMH group has found that, among severely depressed subjects, spending more time awake between 4 a.m. and 5 a.m. (as measured by a sleep study called polysomnography) is linked to increased risk of suicidal thinking the next day."

I wonder if something more general could be inferred - when I'm getting bad sleep (stress-related, mostly), I tend to wake up at around 4AM. My day is often cranky, sometimes I'm completely ineffective until noon.

Could overall sleep levels be more coincident with lower suicidal thoughts?
I think you missed the point.

Was the camera operator x-rayed by the high voltage arc in the tube? (7:47 in the video)

At 7:35 he filmed in a close up the caution label on the tube backside with x-ray warning fine print

Why do you think billionaires would be exempt? If I was the fbi or powers behind the fbi, I would be much more worried about an activist billionaire than an average person. If anything, the surveillance apparatus, it's for targeting the billionaires. People behind the fbi are not interested in going after small criminals who keep the people terrified and in need of the police.

Why do you think zuckerberg tapes the camera on his laptop ?
Yep and there is nothing wrong with a public wall post up until 2016 when Facebook decided to restrict read-access to those public pages by way of the annoying nag prompt. Clicking "not now" doesn't hide the nag prompt enough to call the page 'publicly accessible'. Sorry to be off-topic on this, but I feel Facebook is quite arrogant with this behavior, as their users should be in control of the public status of their posts, not Facebook.
In the simplest configuration have a X-Y stage that you raster, along with Z axis control - generally these are all piezo controlled. Your signal is then acquired by maintaining a constant tunneling current while you raster, so you track the Z axis position as you raster.

This means that you're getting a "pseudo-height" map - if you had a surface with 2 types of atoms, both the same size, but with different tunneling barriers, you would see them appear to be different sizes.
BTW, I really liked the MOOC Visual Effects for Guerrilla Filmmakers https://www.futurelearn.com/courses/vfx-for-filmmakers

Which are what XMPP and Matrix do. Both have username / server routing and for Matrix at least history propagates between participant host servers.

Or you go the Tox / Ring route with a DHT of users and cut out the server alltogether, but the server part is pretty much always necessary for "pretty usernames". Tox has been basically dead in the water for quite some time because they have no effective DNS for users that is universal to all the Tox apps with multiple competing implementations.

My personal takeaway is that if you are going to have a server you should take full advantage of it like Matrix does, because Matrix mobile clients can be push-notify based and not need to always be online to get messages (though Tox et al have ways around that, they are all dependent on storing messages locally to the destination in the DHT, and most users do not want to have to cache other peoples messages).
There is a WIP php parser developed by the community: https://github.com/steffengy/pesty-php/blob/master/src/parse...

And, yes, it does support multi-stage parsing. After the tokens are generated, there is a process! macro which handles them. This is where you can produce an AST.

It's mostly one guy in the Salt Lake City area who enjoys the challenge and uses his video channel to convince a few others to do the same. He's a real expert in animal handling whose obsession with hunting and willfulness (no one could convince him that minks were impossible to tame) seem to help him relate to mustelids. But minks' stubborn and feisty temperaments make them some of the most difficult animals of their size for most people to keep as pets. I follow this community pretty closely.

>>Products fill a known need, solving a problem shared by many organizations. They don't claim that they can help everyone with all problems... but they do solve a specific problem, and if you have that problem, products are good things.

The point is that customers care about solving problems. They don't care about whether they are buying Product A or Product B to solve that problem. That's why you need to keep the conversation focused on the customer, their problems and potential solutions, and not the product.

The Impact of Code Sharing on App Development
In no way am I defending the landlord, and I know nothing about the rents in that area of SF, but the news clip fails to state when the last increase was. It also doesn't mention how large the apartment is, or what a comparable rental in that area would be.

The renter says he's been living there a long time. If the rent hasn't increased in 20 years, there may be an expectation of an increase at some point. That doesn't mean it needs to be 400%, but if the renter has been 'saving' on rent while the rest of the market increases, this may have been inevitable.

At the same time, I'm surprised that there are no limits to rent increase amounts.

"High fashion" as as much an art installation as it is clothing.

Thus what i see with a lot of IT these days, is an invasion of "artists".

Personally i blame it on the web being co-opted by print media. This in turn brought in "media studies", that in turn brought in the "artists".

Notice how again and again there is an attempt at turning the web into a printed booklet.

Early on it was done using flash. These days its JS and mangling the behavior of scrolling.

This analysis sounds close to what he's talking about:

https://www.washingtonpost.com/news/wonk/wp/2016/06/25/why-p...

TL;DR: "Polling showed the areas that had the most to lose and the least to gain from the Brexit are precisely those where the referendum saw the most support. In other words, the places — the most export-heavy regions —most hurt by the economic disruptions caused by Brexit could be the places that pushed hardest for it..."
That's a good point. A very high gain DC amplifier with low noise would have been hard then. A STM needs to sense about 1na at 0.1V, which means a series resistance of about 100 megohms. Vacuum tube voltmeters of the 1940s and 1950s era were getting close, with about 10 megohms input resistance.[1] Sensing 0.1V through 100 megohms with tubes doesn't seem out of reach.

High RF gains are easier to get than DC gains; you can filter out everything but the frequency of interest and reduce noise. That's basically how radios amplify weak signals. But I don't think you can run an STM on RF.

I respect Microsofts push towards reculturing into a developer first company. They have open sourced a lot of code and seem to be making a conscious effort towards transparency. Chakra, VSCode, Azure I think even powershell. Obviously this is market-driven but I think it is a genuine culture shift and I have noticed this consistently for ~1 year. As a big incumbent company I am sure someone will step in and say they are still doing x or not doing y-- sure, however I and I am sure many others, respect the decisions they have made to be a more inclusive company and it seems genuine.
Great article. The only point missed is that password length limits AND re-type fields AND disabling copy and paste are all measures that when, implemented correctly, are supposed to help you remember your password and prevent easy access to reset mechanisms by forcing you to type it twice and not accidentally copy and paste it twice.

Of course, in an era where weak password re-use and leaked hashes are one of the biggest problems facing normal internet users, we really should re-evaluate all the above assumptions.

Or if it's too hard, let email providers handle the login security requirements... Since most places allow email-based password resets anyway.
What are the regulations on those emergency services?
All true, but we also need to get out of the habit of consuming only the most easily scannable information.

As Kahneman explains in "Thinking Fast and Slow", System 2 (the reflective system, the one we want to be working a little on HN) is lazy and prefers to rely on System 1 (the reflexive one that deals in subsecond responses). I think the protests of HN readers when a title isn't trivially digestible or doesn't quite match expectations are largely the grumbling of System 2 that it needs to get up and move around a bit. And that's actually good for us—not the grumbling, but the working a bit. So the expectation to have titles spell everything out is a mildly bad thing and it's salutary to thwart it a little now and then.
All this chatter about Openstack and how it fails brings to mind stories of SAP, and the ways it can turn into a money sink.
Disagree that it's a conscious decision on the developers' part. Developers get told to do this, so they do.
Fortunately, it's not hard to get around this on desktop (for Mac at least) with an applet like Paste Typer. But when I see this on iOS it infuriates me. I use 1Password to generate strong (long) passwords and having to type them out manually is a huge PIA.
Ugh. There were good takedowns of this idea back when the crowdfunding campaign was running. Just off the top of my head, some of the stuff that's wrong with the idea: the surface is going to get covered in grime, blocking all sunlight to the panels; the glass is going to be polished smooth by the tires and dirt, eliminating all traction; the modular glass panels layered on top of modular PCBs are going to separate under stress, so emergency braking will tear the road apart.
Popular by who? Not for app developers for sure.

Are you aware that since Samsung got their hands on Meego, Tizen already went through three SDKs and userspace re-rewrites?

- First it was just Meego Qt SDK renamed for Tizen

- Samsung then replced it with the SDK from their BADA OS, a ugly Symbian influenced variant, including the same Symbian C++ patterns.

- Now it is based on the Enlightenment Foundation Libraries and C, with a C++ wrapper library

But this is only for the hardware where developers are allowed to write native apps, as what Samsung is usually pushing for is their Web app approach.

For example for TVs you need a special contract to deploy native apps.
I think you can make a moral argument in many cases.
There's the historical lesson of the fire brigade of Cassius:
http://ancienthistory.about.com/cs/people/a/crassus.htm

Crassus won a reputation for himself as a soldier in Sulla's campaigns in Italy (83), but fell out of favour because of his excessive greed in purchasing estates at knock-down prices during Sulla's proscriptions of his political opponents. Another source of his wealth was buying up property at risk from fire very cheaply and only then putting his private fire brigade into action. Other sources of his wealth were mines, and his business buying slaves, training them, and then re-selling them. In these ways he came to own most of Rome and increased his fortune from 300 talents to 7100 talents.

(A talent of silver is approximately 32kg, worth about 9 years of labour, so 7,100 talents would represent some 63,000 years of labour income. Very rough modern equivalent, about $2 billion, based on labour.)

I always assumed it was for the same reason sites make you enter your email address twice without pasting - to reduce the chance of mistyping. If you only have to enter something once, then you could easily mistype it and then you end up with an account you can't log in to or even recover. But if you have to type it twice, then the chance is greatly reduced, since you'd have to make the exact same typo twice in a row.

Edit: This is regarding account creation/changes like the PayPal example. I have no idea why login forms would disallow pasting.

>> Nikolai, an elderly pensioner, had just come out to walk his cat.

That's basically all you need to know. An large old mammal tied to a smaller mammal = bear lunch. Do not blame a carnivore for doing what carnivores do. Walk in groups. Don't leash your cat. Make some noise. Move around. Don't sit down quietly on a bench.

>> A person can be standing, gathering berries, and the bear can attack from behind. It’s easy game...

Yes it is, but I suspect the bear (which eats berries far more than meat) is also trying to intimidate a competitor. This tale is like a spearfisher complaining about sharks.

I wonder if that 4am to 5am timeframe is relevant. I've been falling asleep at ~5am for the past few years...

The key part may be "among severely depressed subjects," but I've noticed that whenever my sleep changes (stress-related, too, or a random early meeting) my following day is simply awful and I accomplish more-or-less nothing.

Something that seems obvious now, but wasn't obvious to me until recently, is that people should be realllllyyy protective of their sleep. I guess that study supports that idea.

Straddling Bus That Cars Can Drive Under (China)
But you're an individual, and obviously changes in one individual's income won't affect the housing market. If everyone in your community's income changed, things would be different. The amount of land in an area is fixed, and practically speaking so is the housing stock. Housing is priced at the margin, and if everyone still wants to live in the area, and is willing to pay more now (since even if they paid the exact amount of basic income more in rent, they'd still have the same amount of disposable income after paying the increased rent), then I would expect the price of housing to rise.
Luckily middle click paste on unix seems to bypass everything.

There's a philosophy idea that in order to say we can "see" something, we have to be able to collect consistent information by several different methods. For example if all we have is a STM, then we don't know which parts of the image are artifacts and which are real so we haven't seen anything. But if we have an STM and crystallography, we can have more faith in the features that are common to both images - such as interatomic distances and the geometry of crystal structure. But we still couldn't say that we've seen the shape of an atom since that would look different in each instrument's image.

A great example is people who "discovered" lost cities under the sea. They saw regular patterns of lines on the seafloor in Google Earth and interpreted them as ancient roads or walls. But they were only seeing artifacts from ships that had sailed back and forth in straight lines collecting data. If they had looked both at those sonar scans and some other data for the same location, they would have only seen the lines on one image and been able to conclude that they were either an artifact of the sonar or below the level of sensitivity of the other instrument.

Developers don't need to be mindless code punchers. They can be thoughtful individuals who say, "that's dumb", and then have a discussion with the PM on why that is dumb.
