It appears from the wording that you can still request an opt out, but that they can refuse:
"While passengers may generally decline AIT screening in favor of physical
screening, TSA may direct mandatory AIT screening for some passengers."
Because going through the body scanners prevented the mass shooting or Boston Bombing, right? If we just make airport security more invasive, we'll be safe, right? Wrong.

Security theater is a fool's game. We'd be better off adjusting our geopolitical and societal priorities (such as mental health care, among other things) so that people don't want to terrorize us-- which will never be completed, by the way. Violence is going to happen no matter what, so our task is harm reduction rather than feel-invasive-but-do-nothing measures a la TSA.
I get the complaint about one more OO system, but I did consider all the options and I'm pretty sure that this was the best solution, given how few people will be exposed to it.

There's also a legitimate learning challenge: if I want to figure out which OO system is best for most projects, I have to try them all out. And then the payoff for translating to a common system is small.

That said, for new projects I pretty much use S3 and R6 exclusively. (And it is legitimate to have two systems because they are so different and R6 is mostly needed for internal mutability)
We're lucky that hash collision attacks have a relatively simple mitigation like this. (Although you have to trust CAs to follow the rules and implement it properly, and events of the last few years indicate that CAs need to have as few things to screw up as possible.)

However, we're not always going to be so lucky. The next major transition in digital certificates could very well be to post-quantum crypto due to advancements in quantum computing. Under that scenario, attackers will be able to simply compute a CA's private key and sign arbitrary certificates. There will be no mitigation short of clients ceasing to trust pre-quantum certs. But clients won't be able to do that unless servers are using post-quantum certs, and server operators won't want to do that if it would mean cutting off legacy clients that don't support post-quantum certs.

The solution to this first mover problem is to set a hard deadline after which legacy certs are retired. This forces clients and server operators to act. Pushing back the SHA-1 deadline at the 11th hour as CloudFlare proposes sends a dangerous message that such deadlines don't have to be taken seriously. This message will come back to haunt the Internet in the future.
You need to define skills first and how deep you are talking about.

Someone who are good a at multitude of things but very superficially does not make them more well rounded than one that practices on area more deeply. There are many many many areas that seem to be simple to learn because you can do them very quickly. But thats not what skills are about. Sure you can fake it, but unless you tried to dig deeper into something and learn what it means to learn then you aren't really going to be at a bigger advantage later on in life.

The very act of going deeper into a specific skill is teaching you something that just brushing over a wide area of skills isn't. In fact by going deeper into some of the typical things kids learn you are more likely to be able to also become better at others because you learn what it means to dig in rather than brush over.
I'm guessing that was GPs point, that receptionists and doctors will happily fail to inform patients of this, and rather make separately charged appointments.

While I haven't been to the dentist yet, after living in UK for a year I can testify that the bar for cheating or misleading customers is very low.

As an example, taxi drivers usually pick a longer route than necessary, sometimes driving around the whole city. Especially if they perceive that you are not local.
The TSA should start sedating every passenger, then pack them and put 'em into the planes. Then we will be safe!

Nice write-up, but it's slightly misleading or confusing to not explain that Nat McHugh's image collisions were chosen-prefix attacks. The post makes it sound like the images were the product of some unexplained collision, and then goes on to explain how chosen prefix can be used to forge certificates.
Yeah, the algorithm needs its viral hook: being good enough is not enough, you need to spam 10 people with this message to achieve full redemption.
Several countries now use these scanners. The particular issue (and change) here is about whether people have the right to opt out of passing through them and be screened by an alternative method. In the U.S., that was the case until just now.

According to European law, it should also the case throughout the European Union.

http://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX:320...

Policies in the U.K. were also changed last year to allow passengers to opt out, which wasn't permitted before.

The descriptions of passenger screening on the TSA website haven't changed to reflect policy change. Maybe they expect it to be used extremely rarely?

I'd like to write to my Congressional representatives about this, although it's a bit difficult for me to imagine that Sen. Feinstein will be on my side of the issue.
Yea, I've been thinking about that too. A few weeks ago my 3 year old saw it snowing out and said, "Mom and Dad, it's winter!" A visitor we had over said something to the effect of, "well, actually it's not winter YET, that's not till later in the month." The 3 year old was very confused, as he could clearly see it was winter by the snow outside. I much prefer the 3 year old's simple method for knowing when winter was here.
What's interesting is, flying out of SFO a few weeks ago, I was directed into a line with no body scanners and only a metal detector. I was also instructed to keep my laptop in my bag and my shoes on.

But there was a K9 unit tensa-barrier-ed off that everyone had to walk past.
Clearbit, Full Contact and Pipl all have email lookup APIs. My guess is they are using one or more of these APIs.
That's the goal of packrat. (But it's still a work in progress)
This seemed inevitable to me. There's officially nothing wrong with the scanners, right? Out-opters are just old fashioned, and they're just putting up with us for now until we die out, or they slowly but inevitably loosen the last fingers from our grip on our own dignity.

I've already been denied entrance into the secure area of an airport once a couple years ago, until I went through a scanner, because they found traces of some chemicals on me and/or my luggage. (Was probably from a campfire).
My comment about it being hypocritical was meant to be somewhat tounge in cheek (as vaguely hinted at by the exclamation mark), though I can see how it could be offensive (and wasn't obvious). Apologies.

There is a deeper interesting conversation to be had around this topic though. Unfortunately I'm not in the position to engage in it at the moment and I suspect the tone might already be set in the wrong way (given that a sibling comment here has already called me an asshole).

Pre is a racket. At my home airport, they regularly send non-Pre passengers through the Pre line. They have no way of knowing past that point who has Pre and who doesn't. (In theory I guess they could ask to see your ticket again, but they don't.)

Added to clarify:

I have Pre and it is printed on my boarding pass, otherwise I could not enter the Pre line. They check for the "Pre" stamp both when I enter the line, and when they scan the pass at the end of the line. After that point, I put away my ID and boarding pass and enter a "reduced screening" line (the point where they check your baggage and send you through the metal detector).

What I'm saying is that at my airport, they sometimes also direct non-Pre passengers (who've had their boarding pass checked via a separate line) into the same "reduced screening" line. At that point, both Pre and non-Pre passengers are receiving the same "reduced screening".

It is at this point where I've had the metal detector randomly flag me for going through the image scanner. When I protested that I had Pre, their response was "we don't have any way to know that at this point").

Pre almost always saves me time, so it's not a racket in that sense. But it is a racket in the sense that it's no guarantee you won't end up with a pat-down.
It's theater in the sense that: either the government trusts me, or they don't. If they don't trust me, they shouldn't have issued me Pre. If they do trust me, then I shouldn't need to be patted down.

I'm curious whether there are any valid arguments about the above.
Looks great Max! Was this work commissioned by the city?
Aren't there more secure hashes than SHA1 that are also faster? Like BLAKE2, which can be configured for 128 or 160 bit output?
Fun story: Last time I flew, the scanner detected the surgical plate in my right shoulder. The TSA agent saw the diagram and put his hand on my left shoulder before letting me walk.
Coffee is one specific species of a bean, roasted, and brewed with varying amounts of hot water, milk, chocolate, and maybe a few other ingredients.

There are endless species of fish, with wildly different tastes (salmon, vs tuna, vs tuna belly, vs monkfish liver, vs catfish, don't tell me you can't taste a difference). In addition to fish, there are crustaceans (crab, shrimp, lobster, etc), mollusks (oyster, clam, squid, octopus, cuttlefish), and probably other major animal types I'm omitting.

The comparison is not adequate, sushi is inherently more diverse than coffee.
Best argument possible in favor of not living that far north!
Discreet cellphone pic? Hard to imagine an image being "unstorable".
It's only adding the yuan to a slew of other officially accepted currencies. The yuan is one of the most important world currencies anyway, and Zimbabwe does plenty of business with China already. Anything to help steer Zimbabwe's economy out of its current nightmare scenario is a good thing.
lol, i would hesitate before calling a 5,000 year old culture "superficial". It makes you look superficial.
They have previously said they do not store images with the other models then surprise, they do. Time will tell.
But they already didn't store the images according to their previous policy; that's not a change here.
Hi guys, we are a small team from Europe and we built a website where underprivileged families can share their stories and needs. Anyone can directly fund their needs and we order the products from online stores so they get delivered to families' homes. For many of the families this is the only way to get fresh groceries which is usually the biggest challenge. People can also fund their christmas wishes. To prevent scams everything is transparent and families are submitted by our charity partner which is very respected in our country. We would appreciate any feedback. All best, Nasti
I don't opt-out to be old-fashioned, I do it as protest. You want to waste my time with your security theater, I will surely waste yours.
When you say the opposite can be the multiplication of -2, did you actually mean the multiplication of -1? It's a bit unclear in the example whether the "loss of two" means 1 * -1 = -1 and therefore a relative loss of two, or 1 * -2 = -2 or a relative loss of 3. I always figured opposite meant inverting either the fraction so 2/1 becomes 1/2 or it meant multiplying by -1, effectively toggling the negative sign.
Every programmer needs to memorize the core of their language and framework. Sure, you can use documentation and IDE suggestions, but having plenty in your memory will make you much more productive, and if it need be the case that you need space repetition to memorize, then it's worth the effort.
If you have Pre, they don't usually make you go through the scanners, only a metal detector.
I think this is them giving you a free sample of what you get if you pre-register with them.

Tried some short gmail handles, can confirm. Creepy and stupid. Cloud-based datastores coming with your browser (aka what Chrome has* and probably its competitors too) have better performance, privacy, and UX; I can't think of any reason why I'd use something like this.

* - AFAIU if you set a sync passphrase you also get some (probably limited) form of "zero knowledge" client-side encryption; this makes me hopeful they implemented it properly i.e. "we literally can't access your shit" https://support.google.com/chrome/answer/1181035?hl=en
Can we quit calling these hoverboards?
The problem is, I can't take the chance we get to the airport, go through the Pre line, and then they refuse us passage if my wife refuses the mandatory body imaging scan.
My best guess as to why they changed this procedure is not to increase security (since they know body scanners to be ineffective), but because so many people were opting out that it was increasing delays. I always opt out and notice they try to incentivize me by saying "We're really busy right now, it'll be a while". I always politely wait. Sadly, now that they have this as an option, I doubt I'll want to do much flying anymore.
Adrenal Fatigue: “All I Want for Christmas Is My Health”
Instead of this somewhat pointless magazine article, the phenomenon of astronomical winter and meteorological winter being out of phase can be used to teach numerous important concepts to children (and, apparently, to magazine contributors). Seasons can teach periodicity, phase relationship, the relationship between an input (solar flux) and a system that integrates that input (atmospheric temperature), leading to the calculus of trigonometric functions, or leading to principles of accounting. Really this one simple natural cycle can be the basis of an entire semester of high school science or math. Whining about the calendar is pretty superficial.
So wait, does congress still get to opt-out and be waived through?

Love how their manual suggests the results are stick figures and how they fail to note smartphones could take a photo of the ATR monitor for posterity.
You don't need to memorize ALL the stuff you work with. But it will help to memorize the CORE of the stuff you work with. If you are a Swift or C++ programmer. Knowing/Mastering the core of the language is very doable. it's worth doing it. If you write network programming, memorizing most of the socket functions will help. Improved memory capacity improves productivity.
There is no "pic" at all. The images are never viewed by humans. All you get is a stylized threat alert indicator on a generic silhouette.

If there was a way to do this safely it would be my preferred method of travel.
That was exactly my position. Then I got really uncomfortable during a pat-down at SFO and decided that I'd rather suffer humiliation at the hands of a machine.
Does anyone know if this also impacts children being forced through the scanner? I didn't notice it mentioned in the doc.
Heard about this on "Brain Pickings" and it is on its way. A good read for boys at bedtime? 9 and 11yrs.
And after all... we can definitely trust them on that. Our Government wouldn't make any such claim without telling the truth... would they?
At least the backscatter x-ray machines are gone, now replaced entirely in the US with millimeter-wave scanners.

Personally, I don't care if somebody's looking at my body on a computer monitor. However, I do care if I'm being exposed to extra ionizing radiation for no good reason. Which is why I always opted out of the x-ray machines, but don't really mind going through millimeter-wave ones.

(Obviously, other folks will feel very different about this. If your concern is privacy, the millimeter-wave machines aren't much of an improvement -- though I do believe most of the human elements of the system have been replaced with image recognition on newer versions.)
It's worth noting that this is a peer reviewed conference publication (in POPL no less). So, despite the title a lot of time and thought has gone into the content.
The results ARE stick figures now. The lewd x-Ray goggles photos that we all saw before are gone now.
Looks like you and I will be buying fully refundable tickets from now on...
In most airports I haven't really needed it, but having it when going through security at any of the NYC airports during busy hours can make a HUGE difference. I was flying JFK->Charleston last month, and the regular security line had hundreds of people in it. The pre-check line was literally empty, and I got right through security in about 2 minutes.
dont' care... this doesn't affect the majority of population.. don't care.
I'm sure that C code is maintainable.
>> There should be no reason for us to go through a body scanner if the TSA and DHS believe their background check and fingerprinting are effective.

The general concept of security in layers is perfectly reasonable because no measure can be 100% effective. Combining a few 99% effective measures can get you acceptably close. We do the same thing in cybersecurity.

That said, the TSA is still dumb because of how arbitrary and unfair the requirements can be.
The ecosystem has grown so large that it is nearly impossible for anyone to have any meaningful experience with all of it. Not that it's a bad thing though, choice is always good.
Unless you're "randomly" selected by the little light on the secure side of the magnetometer.
Good question. I see the site as a complement to existing lesson plans. Some teachers have taken the material and presented it in their own style, which I absolutely love:

I don't know anything about educational policy, classroom management, etc. I want to provide the best ingredients I can and let teachers make the best meal they can.
Some gates don't have metal detectors anymore it seems that they are being phased out slowly but surely. And in some cases even if you have the option to opt out you might not even know that you are in a body scanner line as some lines might start where the scanner isn't visible yet.
The problem in my opinion is that body scanners are considerably less effective than metal detectors.

A personal experience from going through on in Germany is that it flagged the passport and boarding pass that i had in my breast pocket which lead to the guy patting my chest like he was a 15 year old getting to 2nd base.
The scanner however had no objection to my key chain which I have had a leatherman micra on which technically has a knife (its only 4cm long and is legal to carry even on air travel or at least it was never flagged for me).
I had a civil and humane US airport experience a couple years ago and I asked about it. The TSA agent said it was because of the K9s sniffing around.
Read AIMA, Know your maths, discrete maths, probability & stats. Take some machine learning courses (free ones at coursera, edx, etc), read up on Deep learning, you should be good to go.
Can you tell me where I may find more info on KDB or how this may compare to more traditional serving options for static resources, HLLs or anything that might fit well in a large tree.

I'm trying to understand exactly what its limitations are though, both in terms of what it can do and when it may be a poor candidate (when lower req/s is ok and greater flexibility is needed).
Driving to the orthodontist was a major pain for my parents, so maybe that had something to do with it. They had to take off work early, pick me up at school, take me to the Ortho and wait around for an hour while the braces were aligned - EVERY month. I'd imagine it's even more of a pain for those in rural areas who have less options. The orthos next to schools made out like bandits. But my parents were also Military, so maybe that's just my experience.
We bought these for our coders at my previous company and I still own one at home. Works great still after 3 years. I bought an IKEA bekant tabletop for it http://www.ikea.com/us/en/catalog/products/40253236/ which was plenty of space.

I find a monitor riser is required as well for actually standing up and not craning my neck.

No, it wasn't coommissioned, but we got a 25.000 DKKR grant for making it. We spent it all on trees, barges and electronics, so noone made any money from it. But it was a really fun project.
> The cosmopolitan worldview that approves of melting-pots was born in response to the terrible failure of nationalism, which "we" experienced to the fullest.

History hasn't ended up yet. I think we're going to see how far the string can be tensed, and whether that multi-culti "solution" isn't the genesis of new strife. Things aren't looking bright.

> If you think freedom of movement is bad, do you think capital should also be controlled?

Actually yes, in moderation. I used to lean libertarian, but not anymore. But that's another talk.

> then the same should be allowed for people, surely?

Why? Capital at least doesn't behead you, people do.
> What's frustrating is comments like yours that describe things that the Web can clearly already do and blame browsers for supposedly being unable to do simple things. I used to think the way you did—that the Web is incapable of rendering a 60 FPS scrollable view—and then quickly discovered that, if optimized properly, there is actually no problem.

I think you misunderstood the widget I'm describing. It is swipeable meaning I swipe to pull the sidebar into view and swipe to push it out of view. If I stop half way the sidebar stops where my finger stops.

Meaning the sidebar has to follow my finger, at 60fps, as I quickly swipe in and out. If such a thing is as easy you claim then a quick demo should be easy enough. I know of no such sidebars on the web that fit this requirement, but am happy to hear all of those devs (and myself!) are just terrible at their (my) jobs.
That was the official reason. Though, backscatter x-ray machines were decommissioned in the US shortly after the EU banned their use due to public health reasons.

There was also that incident where the guy didn't want to go through the scanners, and tried to leave. They tried to prevent him from leaving and said that once he enters the line he has to go through the scanners (even though he was willing to do other things like metal detector, pat-down, etc).
