I think the poster meant that the title of the article "donald trump offered julian assange a pardon if he denied russia link to hack" is the misinformation. Not what was reported in the courtroom. Obviously this is a disagreement between the Republican Dana Rohrabacher and Julian Assange on what was said. A more appropriate title for the article would be "julian assange claimed trump offered him a pardon if he denied russia link to hack".

This is in turn provides fodder for those seeking to add more voter suppression in the name of combating the non-existent fraud.

Requiring an ID to vote is hardly voter suppression and it certainly is not trying to win by any means. The lack of a requirement to prove you are who you say you are is why there is mistrust in the elections. Do you trust everyone in this world to be honest? Oh yes, you don't, because you said "people don't care about the truth, they just care that their party wins by any means".

The simple cop-out solution is to assign one task to managing the entire filesystem, and serve requests from the other tasks, but this suffers from performance problems. If that task has to wait for one particular hardware requests to complete, everything else comes to a halt.

Wouldn't the task be multi-threaded and thus should not have to come to a halt waiting for the hardware anymore than a kernel would?

Comment computers designed for the classroom (Score 1) 217

All of the computers used in the classroom are consumer based computers enhanced in some way to work in a school environment. It would be nice to see someone design a computer system from the beginning to meet the needs of the class room. For example something that deals with:

How does a student efficiently take digitized notes, using both keyboard and pen input, while at the same time reading?

How does the student do math problems or something that requires unstructured input beyond a keyboard while being able to reference the learning material?

To handle either of these scenarios efficiently you would need two independently controllable screens. For example to scroll the reading material for one screen, while typing or writing notes on another.

I don't see what is so awful about non-local variables and I think a realistic interpretation of what happens with entanglement demands it. And by realistic, I mean one that can be understood, can be simulated, and is completely deterministic.

Quantum field theory deals with statistics and unless you think the universe is fundamentally statistical it is not a final theory. And if you piled up a list of issues with QFT besides this one, it would be a long list. So QFT is not a good theory to directly translate into a fundamental interpretation.

So if particles are a superposition of fields, what keeps the particle from dissipating? Where does the field that constitute a particle originate from? Can particle behavior be accurately simulated using just fields? If fields generate other fields, why is there order to any of it?

I can accept fields, but I don't see how they exist without origin. And at least in my conjecture, the fields are generated by what constitutes the most fundamental composition of matter. And there is not evidence to contradict that a photon is roughly a point like particle that travels with a definite position and energy through empty space. And if you had doubts about its position and energy being localized (some people do) you could measure its gravitational effect, at least in bulk form as it travels through space.

Superposition definitely exists. You can measure it. If you're reasonably resourceful you can probably demonstrate it at home.

I don't think superposition exists in the sense that a photon is in a mixture (superposition) of states until measured. Instead I believe a photon is in a definite state at any given time. When you measure the polarization of a photon at a given orientation of the measurement device you can predict with 100% certainty what state you will measure it at when using the same or perpendicular orientation. This suggests to me that the photon has a specific state and is never actually in a superposition of states because otherwise you would expect random results. I don't think you can come up with an experiment that proves superposition is real in this sense.

In the case of entangled photons, I think the photon state is shared until one of the entangled photons interacts and the result of this interaction affects both photons and the entangled state is broken. I have not seen any entanglement experiment that says this is NOT what is happening.

I can agree that Quantum superposition is real in the sense that you can use it with Quantum Mechanics to sum up probability amplitudes that leads to an accurate statistical prediction for many scenarios.

I donâ(TM)t believe the logic runs in circles but that we just donâ(TM)t have the right understanding of the underlying algorithm. Quantum mechanics is statistical, and canâ(TM)t describe how a single particle moves. Entanglement experiments suggest a physical behavior, i.e. the spooky action at a distance, that seems to be a real phenomenon, that QM does not describe for an instance of a pair of entangled photons, but only what happens to many. So if you believe like I do that an instance of entangled photons is real and has no all knowing knowledge of the universe of what other entangled pairs have done then you are forced to accept that Quantum Mechanics or QFT is not the complete picture and we are missing things.

Quantum field theory is a good framework for making statistical predictions, but my understanding is that it does not make any claims that the wave phenomenon seen in the double slit is a real wave that propagates in conjunction with a real point like photon like I describe in #1. While I donâ(TM)t understand QFT very well, I understand the basics of the Feynman path integral, part of QFT, which calculates statistics by assuming a photon takes all paths. This is clearly nothing like #1. Probably #1 is more like pilot wave theory without the mysterious quantum potential.

There is no superposition

That is my guess as well and I think we will eventually learn that superposition is a combination of:

1) the interference of a real wave phenomenon, like the pattern we observe when sending one particle at a time through a double slit

2) the non-local entanglement of photons where measuring one of the entangled photon seems to instantly collapse its new state to the other photon. And where a particle is something like a photon (maybe entangled with itself) going in circles

But I am no scientist and that is just my ill informed guess based on my own attempt at trying to understand quantum mechanics.

Congress should take Trump up on his proposal of a solar powered wall on the Southern border. Trump said he was serious about it. Why can't the country compromise and get this done? Is having open borders more important to the Democrats than a large solar power project?

I did not make the statement, but I agree that it is a bad idea. Whenever you type in your username and password you are risking that someone saw it and can potentially access your account from another device. Obviously two factor authentication helps with this problem. The biometric and pin login that Microsoft supports are good options, but It is still silly that Microsoft does not allow you to do what everyone else allows, which is use a device password.

Windows 10 does not give you an option sign into your device using a device password. One of the options it does give you is to sign in with your Microsoft account. Using a Microsoft account is a bad idea because if someone sees what you type in and you are not using two factor authentication, it gives them access to your account. Apple and I think Google only make you sign into the account once and allow you to use a device password.
