In the 90's USA was sensible. I was flying with a thermos of hot coffee in my carry on. As soon as they took out the thermos and felt the heat radiating from the lid the agent said, "I don't think they would heat it", smiled and passed me thru.

Now when I fly I have to be careful. When they ask purpose of visit I say sightseeing. I used to say tourist, but with my accent that once caused alarm when the agent thought I said terrorist.


I wonder how many actual terrorists they pick up for saying "I'm here for terrorism"

On the other hand, if somebody said "I'm here for terrorism" and the immigration officer laughed that off, imagine the shitstorm if that person turns out to be a terrorist.

For the individual employee the cost of wasting someone's time by escalating the case and detaining them is zero, the potential cost of letting someone slip by is realistically tiny but potentially huge


The point is that the situation must be really crazy if we reach a point where someone (mostly foreigner) saying "tourist" is being confused as to saying "terrorist". Airport are full of tourists, and exactly 0 person on the planet would reply with "terrorist".

>and exactly 0 person on the planet would reply with "terrorist".

Unfortunately you give your fellow humans way too much credit.

Much like the people that rob a bank by writing a note saying to hand over all the money... on the back of their own deposit slip.


So when an immigration officer makes an error parsing the tourist's words, you think the security protocol ought to be to let the tourist pass through the gate?

> I wonder how many actual terrorists they pick up for saying "I'm here for terrorism"

Its like those stupid questions on US immigration forms, e.g.

"Do you intend to engage in the United States in Espionage ?" or "Did you ever order, incite or otherwise participate in the persecution of any person ?"

It's like, really ? Do they seriously think someone who should answer yes will really answer yes ?

Might as well just turn up at the immigration desk, slap your wrists down on the counter and invite them to handcuff you .... why bother with the form !


> It's like, really ? Do they seriously think someone who should answer yes will really answer yes ?

No, they do not think anyone will check 'Yes' to that box.

The purpose of the box is that it's a crime to lie when someone checks 'No', and that tends to be an easy charge to bring.

So, the purpose of the form is to generate convictions for lying on the form.


> the purpose of the form is to generate convictions for lying on the form.

Yeah but if the immigration officer has reason to question you about those sections of the form then surely they have more than enough evidence of the underlying crime anyway ?


No they’re playing the long game. It’s for if they need to deport (and/or jail) you later.

Lying on a customs form is a valid reason to revoke a visa, and it’s an open and shut case.


Is traveling to the US for the purpose of engaging in espionage not also a valid reason to revoke a visa?

Yes. And murder is illegal. And yet, Al Capone was in Alcatraz on tax evasion charges.

It’s often an easier case to prove that you lied on the form when you said you came to the US with no intent to commit espionage than it is to prove that someone committed espionage.

It basically unlocks a second set of potential facts that they can use to bring a criminal case (or revoke a visa, etc).


Intent to commit espionage is not a crime (but committing or attempting to commit it is) Lying on the form is. It is probably easier to demonstrate intent to commit espionage than to catch them in the act.

Wouldn't it be easier to make those things illegal and then prosecute them instead of the lie? For prosecuting a lie you need to prove 2 things, the thing lied about and the lie itself, so it seems like a more difficult prosecution for no reason. Also how does every other country in the world manage to not have these questions?

That crime alone wouldn’t give you a basis for denaturalizing and deporting people who commit certain kinds of crimes.

> Also how does every other country in the world manage to not have these questions?

You sure about that? Many other countries have what would be considered odd questions on their forms.

Also, saying "every other country" is a mighty wide brush. There are a whole lot of countries where the rule of law doesn't come first and they can simply do what they want if they suspect you of anything regardless if they have a law or not.


This is what happens when a legal system and a political system is taken over by specialists with little to no other skills.

Instead of politics being about setting policy to work toward desire outcomes, politics becomes about ensuring the viability of future political processes. Instead of the legal system being about defining crime, establishing punishment and carrying out said punishments it becomes about ensnaring others in legal "gotcha" moments like lying on a form. Society is not safer because of the outlawed nature of lying on a form. Society is not better off because someone is convicted of lying on a form. The individuals who participate in the prosecution are better off because it gives them an opportunity to advance their career.


Making false statements to federal officials is itself a crime. The intent of having those sections is to be able to have legal recourse against people that lie on them, which hopefully deters people that would lie on them from attempting to immigrate in the first place.

Believe it or not it’s a question on the pre-clearance form for travel to the US: ”are you or have you ever been a member of a terrorist organisation” - I always wondered what the rationale for that was

It's easier to deport people for lying on their immigration form than for having been a member of a terrorist organization

But to prove lying you would have to prove being a terrorist anyway...

No, being a member of a “terrorist organization” and the government allows itself latitude in defining that. It’s much easier to associate someone with an organization than to show personal acts of terrorism.

Right but to demonstrate that you lied about X they have to demonstrate X. So by the time you're deporting someone for the lie you could just as easily have deported them for the thing itself.

You're making assumptions the thing they lied about and the thing they are being deported for are the same, and quite often the thing you're actually being deported for is not a reason to deport anyone at all.

You come to the US and make a social media post saying Trump is a big fat dummy head.

You get deported for lying about being in a terrorist organization.


Is that actually a realistic example? I’m having trouble following what’s happening in the US

100%.

This pattern of government behavior is everywhere. One common one is the yellow sheet (form 4473) for buying a firearm in the US.

Here is an example of a question

> “Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?”

No matter the state law, federal law says it's illegal.

So, what happens. At some point you buy a gun in Colorado. Then lets say you get on the news and talk about legalization, or you talk about anything that catches social media popularity and someone in the government doesn't approve of. Well, you better not have any record of a marijuana purchase anywhere, or pictures of you doing it because you've just committed a federal crime and the ATF/FBI can kick down your door as they please.


Having formerly been a member of a terrorist group is different from currently being in one - it may not be illegal, but lying about it is a deportable offence.

Member of a terrorist organization. Did you protest for Palestine action? Then you're a member of a terrorist organization, and they don't have to prove you did any terrorism or planned any terrorism. It's a form of thoughtcrime.

I liked the “have you been in contact with someone with Ebola” questions the kiosk used to ask people entering Canada.

I’m like, uhhhh, I dunno, maybe? A little late to inform me that I was supposed to be asking/testing everyone.


If I knew the answer to that was yes I'd already be at the hospital ...

You say "No", then it turns out you're a HAMAS supporter --> deported.

It could probably be part of the premise for a gag in a hypothetical Liar Liar 2 after Jim Carrey haphazardly finds himself mixed up in one 30 minutes earlier in the movie, so there's that.

> I always wondered what the rationale for that was

One man's freedom fighter is another man's terrorist. An easy way to keep communists out of the country.

And we've seen how easy it is to expand that list with "antifa" groups just recently, with antifa groups in Germany having to deal with their banks closing their accounts because the banks were afraid of getting hit with retaliation in their US business.


There were no liquids rules in the 90s.

https://en.wikipedia.org/wiki/Liebeck_v._McDonald's_Restaura... "Liebeck's attorneys argued that, at 180–190 °F (82–88 °C), McDonald's coffee was defective, and more likely to cause serious injury than coffee served at any other establishment"

https://en.wikipedia.org/wiki/Coffee#Preparing_the_beverage "Optimal coffee extraction occurs between 91 and 96 °C (196 and 205 °F).Ideal holding temperatures range from 85 to 88 °C (185 to 190 °F) to as high as 93 °C (199 °F), and the ideal serving temperature is 68 to 79 °C (154 to 174 °F).

I'm aware of the injuries she incurred. I think it is frivolous because hot temperatures are simply part of the nature of coffee. McDonalds did not select the vehicle with out cup holders for Stella. McDonalds did not select the sweatpants that Stella chose to wear. McDonalds didn't spill the coffee in her lap. Lastly, even non-coffee drinkers are aware that coffee is hot.


Normal people do not serve coffee anywhere close to that hot. Sorry to burst your bubble.

"You're right, it's not infinite, but we are in no crisis now or in the foreseeable future."

Have you not heard of climate change influenced by fossil fuel burning, or are you a climate change skeptic?

The general consensus is that climate change is a crisis, now and in the foreseeable future.


Yes of course, but i have not heard of a reasonable action plan given the world's population and basic human nature.

Hang dry clothing to avoid the drying machine issues all together and it is much gentler on the clothing.

I believe traffic lights currently use three bulbs, red, yellow and green. Even without color a computer system can easily determine when each light is lit.

If there are single bulbs displaying red, green and yellow please give clear examples.


Flashing lights over rural intersections often do that. There is only one color there (yellow or red), but position is not a signal


Have you driven in America? We have the craziest lights you've ever seen. And that's just in my state


How about turn signal vs brake lights?


> How about turn signal vs brake lights?

Potentially as extraneous as range to a surface that a camera can’t tell apart from background.

More to the point, everyone but Tesla is doing cameras plus Lidar. It’s increasingly looking like the correct bet.


> doing cameras plus Lidar

At what proportion? Is it mostly lidar or mostly cameras? Or 50/50?

> Potentially as extraneous as range to a surface that a camera can’t tell apart from background.

I guess yeah for backside of the car you'd probably better off measuring actual actions.

How about when you come 4 way stop. LIDAR is useless as it wouldn't recognize anyones turn signals.


What do you mean by proportion? They are different data sources, and their usage is determined by system design.

eg A driving decision system needs to know object distances AND traffic light colours. It doesn't particularly need to know the source of either. You could have a camera-only system that accurately determines colour and fuzzy-determines distance. Or you could have a LIDAR-only system that accurately determines distance and fuzzy-determines colour.

Or you use both, get accurate LIDAR-distance and accurate camera-colour and skip all the fuzzy-determination steps. Or keep the fuzzy stuff and build a layer of measurement-agreement for redundancy.

So then the question becomes, what's your proportion when deciding whether to stop at a traffic light? Is it mostly light colour or mostly distance to other objects? Or 50/50?

I'd say it's 100/100.


Sounds like a solved problem and you can buy a solution with a perfect accuracy?


I don't read the previous comment as either "you can buy" nor "perfect accuracy".

Like them, I don't understand what you're asking by "proportion". Bits/second? Sensor modules/vehicle? Features detected by the AI?


Is there a point you're trying to make?

Because it really feels like you're just JAQing off, either to come to some "gotcha" moment or a pseudo-intellectual exercise. In either case, the questions feel bad faith.


Who said that?


> At what proportion? Is it mostly lidar or mostly cameras? Or 50/50?

What proportion of your vision is rods or cones? Depends on the context. You can do without one. But it’s better with both.

> How about when you come 4 way stop. LIDAR is useless as it wouldn't recognize anyones turn signals

Bad example. 99% of a 4-way stop is remembering who moved last, who moves next by custom and who may jump the line. What someone is indicating is, depending on where you are, between mildly helpful and useless.


The grandparent mentioned "world wide mesh network internet". Is Amazon Sidewalk world wide? The link you posted only mentioned it launched in the United States in 2021. https://www.aboutamazon.com/news/devices/everything-you-need... shows a coverage map with large areas unserviced.


https://en.wikipedia.org/wiki/Gait_analysis#Surveillance

It may not be an issue for you at the moment, but outright dismissal will not keep you safe.


I work in this space and have for quite a while. There is no productized gait analysis software available to the commercial markets.


Surely archived footage would be ripe for automated analysis once the tools are commercialized.


Yes, in the same way stored passwords of today may eventually be broken by the quantum computing tools of tomorrow.

The post I replied to implied that gait analysis is a viable alternative option. Gait analysis is not an option today, or this year, or even in the next decade. There is no data supporting the claim that it can be done reliably enough to get down to practical reidentification use cases.


To add to the comparisons. Protonmail is showing as 180 MB on GrapheneOS. Add in user data and cache and it's 495 MB. I don't consider myself a big email user so I am a bit appalled.


Pixel OS16 with fastmail is 20MB for app, 60 for usercache and 7 for cache. I use it once or twice a week if that


Of course not. There might be a social media article but nothing verifiable.


I do not understand the attraction or rather the glorification of going to a Cafe alone.

"It was pure delight. Every element. Or rather, the non-existence of any element. No phone. No headphones. No tablet. No laptop." I believe I can do this anywhere.

They talk about interactions with people in the cafe but it is primarily avoiding interactions.
