### P vs. NP Problem Linked To the Quantum Nature of the Universe

Re:NP vs. P doesn't exist in the real Universe (199 comments)

Of course the computer is thinking.

Our problem is that each time computers advance, we take away from them by saying that whatever they are able to do now is not thinking.

Furthermore, we take that away from people also: since computers can now do X, it means that X isn't thinking, and it also isn't thinking when people do X, as was mistakenly thought before we figured out a way to do it with computers.

All computation is a form of thinking. When a vending machine gives you a snack, it performed thinking. Moreover, it exercised free will.

### P vs. NP Problem Linked To the Quantum Nature of the Universe

Even if the Schrodinger equation does purport to describe the real behavior, the problem with the article is that it assumes that the parallel superimposed states are accessible to us on a small scale, but not on a macroscopic scale.

But in fact, aren't they theoretical states? When it's time to observe a particle or whatever, we don't see all the states. We see one, and we just can't predict which one.

So we cannot observe a cat in two states such as "dead" and "alive" because we can't do that for a quantum particle either.

The parallel universes (PU) interpretation of QM gives a plausible intuitive explanation why. Maybe the Schroedinger equation is solved fully, but across PUs. Since PUs are available, the solution is unhindered by computational complexity (assuming P = NP, which is probably the case).

Cheap and fast splitting of reality into unlimited numbers of branches of parallel futures trumps P = NP.

Another problem with the whole thing is that (supposing the evolution of behavior in the universe to be a computation) the objects in a computed simulation are not aware that the simulation is going faster or slower, because their time is also simulated. If a simulation has to pause and solve an instance of an NP-hard problem, the entities being simulated do not perceive this extra passage of time: that is happening in the simulator's time, not in simulated time!

### Linus Torvalds Suspends Key Linux Developer

It is obvious from the internals of systemd that it's designed and written by B grade talent.

I agree with the crackdown. (353 comments)

because these app providers are skimming money from the drivers. To hell with them; they deserve to be curtailed because of their greed and their stupid system that is vulnerable to such a crackdown.

There should be a true peer-to-peer system that doesn't skim any money, based on some light-weight "tracker" servers whereby clients can make initial contact.

Everything open source, too.

Then there is no place where to send a cease-and-desist letter. Shut down one tracker, four more open up elsewhere. Perhaps even operated in the cloud somewhere, in another country or whatever.

Make it so that anyone can add 100 lines of PHP to their server to add contact node to their server.

Come on, in an age where you can get any movie, music, warez or pr0n with complete impunity on a global scale, Seattle, of all authorities, is gonna stand between you and getting a ride with someone? It simply does not compute.

Not such good news for getting paid. (136 comments)

Public results? Anyone can take your work and use it for something profitable, while you scrape for grants to continue.

### US Government Embraces Bitcoin in Hearing on Virtual Currency

Anyone in politics should absoutely love this! (233 comments)

Bribes, prostitutes, extravagance ... all require anonymous, untraceable forms of money.

If politicians didn't require it, governments would have banned cash long ago.

### Most Drivers Would Hand Keys Over To Computer If It Meant Lower Insurance Rates

If you have a lower history of traffic violations and a lower insurance claims record than a robot, you should pay less, and vice versa.

### ACLU: Lavabit Was 'Fatally Undermined' By Demands For Encryption Keys

If a en e-mail service CAN disclose keys ... (230 comments)

it is NOT secure!!!

Secure communication means that only you or your friend on the other end can disclose secrets, not the service in betwen.

If you run a truly secure e-mail service and Uncle Sam wants keys, the correct response is "sorry, can't help you; we do not have any keys".

### Ask Slashdot: How Best To Synchronize Projects Between Shared Drive and PCs?

DO NOT USE GIT! Or you will be sorry. (238 comments)

Git is absolutely not a good first version control system for people who are clueless about version control. (Such as, evidently, your developers).

Git requires prior experience with at least two simpler version control systems. In git, you often run into scenarios that require you to understand its complicated repository representation so that you can choose the best steps to unravel them, based on understanding the ramifications of each approach.

The implementation of git is not hidden from the user behind a robust set of "no brainer" use cases.

The decentralized model alone will confuse the heck out of workers with no prior version control experience.

Use a system that has a centralized server from which working copies are checked out, like Subversion.

### Should the U.S. bomb Syria?

If lives were important, we'd be in Africa solving poverty and treatable disease.

You cannot compare people being murdered to people who do not know (at least according to popular perception) how to eke out a living.

### Should the U.S. bomb Syria?

This Slashdot poll is about whether to bomb Syria, not whether to go after the oppressive regime somehow.

"Innocent people were gassed ... so let's bomb the fucking place too?"

I'm in favor of cleanly executed assassinations that take out all the correct bastards one at a time.

### Publisher Sues University Librarian Over His Personal Blog Posts

Re:Can't they get even in some other way? (126 comments)

Ah, in the United States perhaps. But if I express that opinion in Canada, it might in fact be defamation. Oops!

### Publisher Sues University Librarian Over His Personal Blog Posts

Can't they get even in some other way? (126 comments)

For instance, the publisher could start a blog in which they call the librarian "Mr. Poopy Pants".

That is essentially the equivalent of what he did to them.

If I think that some publisher's output is poor, that is my opinion. It is not libel. You can't sue people for having standards (even completely vague ones that change daily) and for claiming that some things don't measure up to those standard (in no objective way).

Libel would be if I claim that, say, the publisher cheated someone out of ten thousand dollars, when in fact that is false.
