Actually, no. The point of light in the cloud will not move faster than the speed of light, as this violates the special relativity theory.

Please remember that pointing a laser beam onto a cloud is like transmitting information. For example, by turning the beam on and off ala morse code, a message is transmitted. So it cannot be faster than light.

I think it is wrong to say simultaneity is wrong. The fact that the two clocks are correct does not mean simultaneity does not exist, it only means that we cannot measure simultaneity with clocks.

The fact is thinga happen in parallel in the universe, and so simultaneity exists, because for any event another event would have to have happened at the same time.

It is the Sun.

All we need to do is to create enough solar cells and enough batteries so as that we can always have power.

If the Sun is producing 4000000000000000000000000000 watts per second, we are, as humanity, simply fools, in that we have the absolutely best power source right above our heads and we are not using it.

The solution of the problem is pretty easy: replace the chairs with beds. Not normal beds (of course), but bed/chair hybrid boards that are reclined in such a degree that allow the person to relax, stretch his/her body, take a nap etc, while at the same time have even more passengers in flight.

Comment: Should we put more whites in the NBA too? (Score 0) 593

The NBA is dominated by blacks. How come there isn't a problem there? Shouldn't the NBA have more diversity?

You see how stupid this thing sounds, doesn' it? People are drawn to whatever they are good at or like to do. Let the white males be programmers and the black males be athletes or whatever they like. If the blacks want to be scientists, teachers or anything else, let them be. It's not really a problem...

Comment: Buffer overruns can be prevented at compile time w (Score 1) 231

by master_p (#46911811) Attached to: How To Prevent the Next Heartbleed

Buffer overruns can be statically prevented at compile time without any runtime penalty.

All that is required is that the type system of the target programming language enforces a special type for array indexes and that any integer can be statically promoted to such an array index type by a runtime check that happens outside of an array access loop.

Array indexes are essentially pointer types that happen to be applicable to a specific memory range we call an array. Memory itself is just an array, but for that specific array C gives you special types to access it, namely pointers.

Could it be that neurons simply don't store new information except the first time and that all experiences are stored as an incremental backup, i.e. it's only the changes that are stored?

This solves the stability-plasticity dillemma: the first experience that comes is stored as a whole, and then similar experiences are only stored as a delta from the initial experience - thus allowing the brain to maintain some 'forever' experiences like touching a hot stove but also be flexible enough to remember new experiences.

This can also account for the deja vu effect - recalling experiences that are similar.

The problem is that Communism only works on paper. In practice, greed can easily kill it.

Capitalism can be killed too by greed, but at least in Capitalism there are enough conflicting forces to slow down the process.

In Communism, there is only one force, the Communist Party, and so everything can go to hell really fast.
