No, because to do so every program needs to support 2^n different configurations, where n is the number of services they could potentially make use of. Most developers aren't going to bother, so in practice you either run a set of services or don't run the program. And at that point it makes sense to define a standard set which a program can expect a server or desktop to have.
And who knows what "the physics" will be like in 20, 50, 200 years time?
Theory of Relativity didn't mean you could suddenly ignore gravity and just jump into space. New physics might unify and connect phenomenom previously thought unconnected, but they won't make them go away.
Also, the reason we don't currently use fission rather than coal is political, and the same politics will also keep either hot or cold fusion from being used, should either ever get functional. People conditioned to fear anything nuclear will not change their minds until the rolling blackouts start, and at that point it's far too late.
In other words - just because currently "the physics" says "cold fusion can't be done", is no reason to say "so we shouldn't try" - that way lies stagnation.
By all means, keep trying to jump into space, just don't expect other people to pay you attention until you succeed and can prove it.
No form of currently-achievable propulsion yields a higher Isp than a fission fragment rocket, with the exception of photonic / magnetic sails, which are impractically low thrust for interplanetary travel.
You have it backwards: the longer the distance, the better option solar sails are, since low constant acceleration means the yacht will eventually overtake the dragster. It's in the short-distance travel - like Earth to Moon - where sharp but short acceleration shines. Amd of course you need it to get off from the planetary surface, at least for now.
Of course, all this is ignoring the possibility of revolutionary new materials. There's no theoretical reason why a solar sail couldn't generate the 1+g of thrust needed to lift from Earth's surface, it would simply have to be very strong and light, perhaps made from carbon nanotubes or even plain graphene sheets.
Psychological bullying that leads to things like rape or slavery are not that uncommon. There have been cases of modern day slavery where people were not physically restrained or abused but none the less felt unable to leave and worked for free, sometimes for years.
You just described minimum wage employment, and we as a society have already decided that's awesome as long as the exploiter goes through the motions to let us pretend it's voluntary. So we probably shouldn't be surprised that some people drop the mask of civility, nor shocked of the grinning skull beneath.
But you have to admit, a system that makes the slaves compete for wearing chains while repeating slogans about freedom is pure evil genius, farcical as it might be.
As for relationships, it's a well established pattern for people to stay with abusive partners even after they become violent. It's just as bad when the abuse is psychological, and just as much rape.
Call me all the names you want, but I saved 10% and you didn't. I can't be caught or punished. I submit that the system is stupid, not me.
The system is built around the assumption that most people aren't sociopaths and take into account effects besides their individual interests. This is a reasonable assumption, because no system can survive the majority of its members being sociopaths. So your submission is incorrect.
You're also incorrect about not being capable of being caught. Of course you can be; all it'll take is one of those contractors being caught and ratting you out. Even more likely your punishment will arrive in the form of shady contractors doing substandard job, for which you have no ability to seek relief without exposing yourself.
But ultimately it doesn't matter. Every organism has some amount of parasitic load. Why would memetic ones, such as Finland, be different? Keep boasting of being a sufficiently insignificant flea to go unnoticed if that's the most impressive thing about you.
So, are you saying that it's OK to rape and beat your wife as long as you don't leave marks?
And absent signs of physical trauma, you won't believe it happened?
Absent signs of physical trauma, do you have any kind of evidence it happened? If not, why would you automatically believe a person has committed a heinous crime just on another person's word? Malice is equal opportunity.
Violence leaves marks that can be examined, but it's not in general possible to determine afterwards whether someone consented or not. It's bat that a criminal might walk free, but it's also bad that an innocent might not. If you have a solution to this situation, do feel free to share.
I'm not arguing right or wrong on what the guy did, but either that is a huge stretch on saying what "stalking" is, or the law was written FAR too broadly!!!
Actually, tracking someone's every step seems like a textbook case of stalking.
You see, being insensitive to one's place of birth is RACIST.
I congratulate you on your honesty, and so do the mods it seems. A lesser man might had tried to claim he meant recent locations, but you came right out and admitted it's about immigration.
How about we call it what it is: an idiot parasite not only making others carry his share of upkeep costs of the society, but also providing an excuse for those pushing for complete abolition of cash due to your inability to not brag about your own "cleverness"?
How can we be expected to respect law enforcement when they pull crap like that?
Because they'll kill you if you don't.
The problem with getting though with crime is that it means the police is expected to be though. And this is how though guys act. This is, always has been, and always will be, the price you pay for demanding "thoughness": you'll get fascism.
However many of the uses convert electric energy to things like formulation of chemical bonds that require energy for creation.
By definition bond formation doesn't require energy but releases it, since "bond" is something that requires energy to break and energy must be conserved. It's setting up the preconditions for bond formation that requires energy, possibly less than is released when the bond forms.
At one point when I was a system administrator and we only required 6-digit passwords changed every 90 days,
Why did you? Require the password to be changed periodically, I mean? The only thing it seems to accomplish is make sure the users will either pick weak passwords or resort to post-it notes.
If you write your pin number on your ATM card are you not at least partially to blame when a thief finds the card and cleans out your account?
Certainly. But what if you didn't, and simply have an ATM card some malefactor manages to use to get money without your PIN due to bank's bad security? Because it seems like having your account cracked is closer to that.
Of course, a more important question is: does it matter? If I run a red light and drive over you, should I get off lighter because you didn't look both ways before crossing? Yes, you were dumb as hell, but does that mean that you deserved to die and if so, on what basis?
This is a question that we should put some serious thought into, since it has ripple effects on a lot of different areas of society.
Closing scene is the last few rocket ships barely escaping Earth as it disappears, with innumerable other rocket ships not making it.
Collapses, not disappears. The hole is hollowing out the insides of the planet, and when enough is gone, the no-longer-supported crust cracks into pieces that fall in as magma sprays everywhere. And of course we have terrible earthquakes and volcanic activity leading up to the final doom.
Obviously none of it has to be scientifically accurate, so pedants please don't start trying to pick the plot apart, because it's just too easy pickings.
Well, scientifically speaking the entire mass of the Earth would only create a hole the size of a centimeter or so, so it'd take a long time for the entire planet to plunge down that drain. The "superball of death", on the other hand, could easily trigger massive quakes and tides at every bounce due to the tidal forces, despite the hole itself being very small.
How is the HR process not symmetric? Whatever would cause the dissolution of the black hole--how would the same process happening in reverse (matter falling into the black hole and anti-matter escaping) not cause equilibrium to be maintained?
Matter and anti-matter annihilating each other produces energy. That energy remains trapped in the hole, so it's mass is unchanged (energy = mass * lightspeed squared). So whether matter or anti-matter fall into the hole, its mass will grow.
What's happening with Hawking radiation is (AFAIK) that particles are actually ripples in a field - for example, a photon is a ripple in the electromagnetic field, and an electron is a ripple in the "electron field". If these ripples are well-formed waves they're said to be "real" and have measurable quantities, such as energy. Otherwise they're "virtual" particles. That's what's meant when they say electromagnetism works by exchanging virtual photons: charged particles cause disturbances in the electromagnetic field, which affect other charged particles.
Now, quantum mehcanics has a number of paired properties, where both members of the pair can't have an exact value at the same time. Position and momentum are perhaps the most famous such pair, but another is the value and rate of change of a field. That means that no field's value can be permanently zero, because then we'd know both the exact value (0) and exact rate of change (also 0). And because they can't be permanently 0 despite having to average to it, they must ripple randomly, a state of affairs often referred to as "quantum foam". Since particles are ripples in these fields, this process is usually depicted as a pair of virtual particles coming from nowhere, living for a while, and then meeting again and canceling each other out.
An interesting property of these virtual particle pairs is that if they receive at least as much energy as corresponds to the pair's rest mass, for example by being accelerated in a black hole's gravity field, they become "real". That is, random ripple turns into a well-defined wave that's not going to disappear, but is going to continue its existence as a real particle. According to current cosmological theories, this is how all matter originated, with the Big Bang acting as a source of energy. This is also how particle accelerators work: smash a stream of particles together hard, so the energy of the collision makes virtual particles materialize.
So what happens is that if a pair of virtual particles is brought to existence near the even horizon of a hole, one might fall in and the other fly away. The one flying outwards loses energy - it's rising against gravity, after all - but the one falling in gains more than enough to offset that, since it gets pulled harder and harder the farther it goes. So, the pair of particles as a whole gain energy, and if that energy exceeds the pair's rest mass the pair turns into real particles. Since energy must be conserved, it must come from somewhere, and the only available source is the black hole's mass, which is diminished as a result. The falling particle is basically carrying a bill with it, which negates some of the black hole's energy. And since it's the direction of gravity that determines which particle gets the bill, it's always the one falling into the hole, making the process asymmetric.
But then again, the actual math is beyond me, so I could be completely wrong here.
Dear Scientists, Please stop trying to create black holes. I would prefer not waking up in the middle of some random night feeling a tug on my body and seconds later falling into the aforementioned black hole to my death.
Why hasn't this been made into a movie already?!?
A black hole created at, say, Large Hadron Collider, would fall into Earth's center and then continue onto the other side, rising to the surface only to fall again, in an essentially chaotic orbit, snapping a person here and another there, slowly growing as it ate Earth's innards like a hookworm, surrounded by a growing spiral of white-hot remains of its feast. It's perfect material for a horror movie, or a disaster one, or an artistic one, a monster movie, or a Michael Bay explosion fest.
The production of Hawking radiation in a gravitational black hole relies (and relies only) on the presence of a horizon.
Does it? Because from what I've understood, it's caused by virtual particles getting sufficient energy from interaction with a field to become real particles, and even horizon is simply the boundary above which particles so produced can escape. If so, then any strong enough field should produce Hawking radiation - for example, a strong enough electric field would produce a stream of electrons and positrons moving in the opposite directions.
And it is still correct. There is no need to panic. Ebola gets WAY more press than the severity of the actual risk justifies.
Reiterating a claim is no evidence for it.
First off, ebola is NOT "highly contagious". It's actually rather hard to get. Unless you have been in direct contact with the sweat, blood, tears, feces or other bodily fluids of a symptomatic ebola patient then you have nothing to worry about.
You do realize this puts it one step beneath airborne pathogens like the flu, right?
It is incorrect that "every" pathogen has to potential to become a "deadly and highly contagious disease". Go talk to an infectious disease doctor and they will tell you that the biology of most viruses and bacteria prevents them from ever becoming a threat to humans. It's actually quite hard for that to happen even in a rapidly mutating virus which ebola is not.
Ebola is, however, already past that hurdle. It has crossed the species boundary and is adapted enough to its new human hosts to overcome the immune system in most cases. All that remains is slight tweaking of the exact parameters of symptoms to optimize spreading.
What you are suggesting is almost as unlikely as all the air in the room suddenly deciding to be on just one side of the room because, hey, it's theoretically possible.
Either you have no idea of the magnitudes of probabilities involved or are lying for rethorical reasons. Either way, your absurd exaggeration accomplishes nothing.
No, there is no need to panic. Get a grip on your fantasies.
You know, I've heard that many times now, yet Ebola continues spreading. And every new case gives it new opportunities to evolve further. So perhaps it would be better to panic and spend some serious dough to crush the outbreak while it's still possible, rather than wait for it to turn into the doomsday scenario a deadly and highly contagious disease has every potential to become?

If it's a solar thermal plant, those would be perfectly ordinary steam turbines, which are a quite mature and time-tested technology.

Americans brought this on themselves.
Most robbers in Finland grab the loot and get it out of the country ASAP. That's the utopia of free flow of capital and workers within the EU for you.
