There was an actual NASA project that briefly claimed to have detected some miniscule accelerations driven only by EM waves. I think these claims were later lost to measurement error.
See the wiki:
NASA Eagleworks reported small thrust under vacuum.[70] Tajmar et al. (2022): no thrust across wide frequency band; any anomalous signal below photon-thrust limit by at least two orders of magnitude.[21]: 31, 42–43
Mumble, something. Magnets do no work. Mumble, mumble.
This is still a big deal result with a lot of physical significance if it holds up.
Full Navier-Stokes are / were understood to model all of the important physics associated with continuous domain fluids. (Continuous domain here means we approximate the many, many particles of the fluid as a smooth, continuous substance).
In particular, Navier-Stokes are supposed to fully model fluids with turbulence. Turbulence is an everyday phenomenon that you can reproduce for yourself in your kitchen sink, and yet it is extremely difficult to formulate a mathematical function for it. Turbulence appears to be random if you look at it, and yet if it is produced by NS, then it is not random. Solving even the numeric approximations of NS for turbulent flows is difficult because the flows exhibit severe variation in velocity over wide ranges of time and distance scales.
Anyhow, if NS is a good physical theory it has to have a physically realistic solution to every physically-possible set of initial conditions and environmental forcing functions. In math terms this mainly means that all of the velocities, pressures, and forces have to be finite and smooth at all times. Step discontinuities don’t really occur in the real physical world (although they do approximately occur).
This result would mean that NS is not the end all final theory for classical continuum fluids. The scenario constructed by OpenAI is claimed to be one that can (at least theoretically) be setup and run in the real world. But if we did that, the real world is certain to do something else besides the infinite flow velocity vortex that OpenAI claims NS predicts. What would really happen in that experiment? Who knows. We’re gonna need to find some new physics to find out.
compel” limits bit is limited to US citizens
This is completely not true. The 4th and 5th amendments apply to everyone.
that even then, they can confiscate your phone
If they do this without getting a search warrant from a judge, you can sue for the return of your property. You can make them justify to a judge why there is probable cause that your property will yield evidence of a crime.
they can refuse to let you fly
This is a thing that can happen, but you can also sue the federal government to challenge your wrongful placement on the no fly list. People have sued and won and been awarded costs and attorneys’ fees
confiscate your passport,
This can happen if they think the passport is fraudulent, invalid, expired, stolen, or if you owe taxes, or are a sex offender that needs an annotated passport, or sadly if they think you are trans.
For many of these causes, the simplest solution is to apply for a new passport. For the trans victims, the issue is currently in federal court, and I am hopeful for a positive outcome.
deport you to the country of their choice.
At this point I assume you are talking about non-citizens, non-LPRs. If such a person is refused admission they are preferentially deported back to wherever they came from. At land borders, that is cheap and easy. Air carriers are required to transport passengers back to origin at the air carrier’s expense when CBP so demands. (This is why airlines check your documents thoroughly before they let you go.)
If for some reason the person’s travel origin refuses to accept them, then the next preference is a country where they have citizenship or strong residence ties.
With the exception of the original set of CECOT flights, which were done in actual contempt of court, true third country removals are the last resort both in law and in actual (however fucked up) practice.
The people who have been sent to the strange African countries have problems with no documents, no proof of citizenship, their true home country refuses to accept deportations from US because of bad relations, or they have withholding of removal because of a legitimate fear of torture or persecution in their home country. That’s not something that’s going to happen to the vast majority of people that show up at an airport with actual good documents.
Here’s an important point from the activist distress code case: CBP had a plan to target him for this treatment in advance before he showed up at the border checkpoint that day. The airlines send them passenger manifests 72 hours in advance.
100% of the time, if they take you to the little room, start asking you questions, and want to look through your phone, they already believe you’re guilty of something specific.
If that happens to you, you need to understand that you have already been the “target” of an investigation. There is nothing you can do or say in that room that will convince them otherwise. The best thing you can do is shut the hell up, do as little as possible, and don’t make their case for them.
And don’t believe anything they’re telling you either. The cops can lie to you, but you can’t lie to the cops. It’s a crime.
I think I’m at low risk.
I power my phone off prior to arriving in the US and keep it off until I leave the airport.
Under US case law, you can be compelled to give up a thumb print or face ID with a search warrant. But you cannot be compelled to give an unlock code, because the code information is testimony, and you have the right to remain silent.
If they insist on seizing my phone unless I unlock it, my plan is to ask for a lawyer, shut the fuck up, let them seize the phone or whatever, then sue them later to return it.
This plan works for me because I’m a US citizen, and I have an absolute right to enter the country. If you are not a citizen or LPR the local CBP officer has the discretion to refuse admission even if you have a visa. So that’s a real consequence to non cooperation.
Don’t lie to the feds about not having a phone if you really have one. That’s a separate crime all by itself.
Plus, they dropped Callaway Golf after their horrific ad depicting violence against women.
Wait… What?
A 2.5 million private jet is, uh, probably not new.
The smallest Very Light Jets, like the Cessna Mustang or HondaJet, start around $5 million new.
So you’re probably looking at a decades old plane, almost certainly not enough room to fully stand up, and possibly no lavatory.
A true FAR PASCAL enjoyer, I see.
Obstruction of justice is a charge. Destroying evidence to frustrate a criminal investigation that you know about could qualify.
The fifth amendment protection against self incrimination applies to statements. It does not protect actions such as pressing the factory reset buttons on your phone.
The license holder is attaching additional terms and conditions that are incompatible with publicly disclosing the driver source code.
It matters a lot whether she is a US citizen or not.
If she’s a citizen, then she can shut up / lawyer up. She has a fifth amendment right to not divulge a phone or computer password, code, pin, or whatever. CBP can detain her for up to several hours, but at the end they have to either charge her or release her into the country.
If she’s not a citizen, then things are a lot tougher. She still has constitutional rights, including the fifth amendment. But CBP has a lot of leverage, because they can rule her inadmissable. Once that happens once, then it can become really hard to get readmitted later, because this “strike” is on your record.
The main thing that is tripping up green cats holders at the border currently is old criminal records. That DUI or marijuana or shoplifting charge or conviction from 20 years ago is often not enough dirt to get an LPR deported, but it is enough dirt to deny readmission if they happen to leave voluntarily.
Encrypted data channels can still be vulnerable to man in the middle attacks. Like when you connect to an unknown host with SSH, and the client pops up a big warning.
In this case, ICE or whomever sets up a “valid” cell tower that your phone connects to, and they (law enforcement) route your packets onto the rest of the Internet. They can decrypt the 5G data, and see all of the IP headers. They can’t necessarily read the TLS traffic, such as https. But most important of all, they can log all of the IMEIs that connect, which effectively gives them a database of all of the protestors.
The use of Stingray by US law enforcement has been challenged on grounds that the law enforcement agencies have no spectrum license. Those challenges seem not to have found success.
On the other hand, prisons in the US have been stopped from operating cell phone jammers on prison grounds, on the same complaint of no spectrum license.
The wrinkle in this case is that the thumb print giver was in parole. The conditions of parole stated that failure to divulge phone pass codes on phones could result in arrest and phone seizure “pending further investigation”. The parole conditions didn’t say anything about forcible thumb print taking.
So the logic here seems to be:
Especially talk to FSF if this “well known debugging tool” is a part of the GNU project, as FSF has the power and standing to enforce the copyrights on GNU software.
Ctrl+alt+delete was a separate interrupt line direct from the keyboard. That is, when you pressed the three keys, the interrupt signal was asserted, causing the CPU to jump to the interrupt service routine, which should be in the source code package.
Latin class is always the best class.
Other foreign languages: you learn boring stuff like “Hi, my name is mkwt. What is your name? How are you?”
Latin: you learn the words for swords and various other weapons, and six different words for kill in the first two weeks.
(They do this because they’re prepping students to read Julius fucking Caesar as their first exposure to “real classical Latin.”)
