And are such things, with autonomous capability including docking, available now, as autonomous quadcopters are? The point is that this is not a research exercise, this is going into day by day carrying parcels people urgently need delivered safely. If the sphereboat is available off the shelf (and as well as being unsinkable can also not be wrecked on the shore or washed out to the open ocean)), it might make a good alternative.

Of course, this is also a tryout for more generalised future delivery systems which, being overland, would not be appropriate for a boat.

Certainly German police would take a much stricter view than US police, and random people are much less likely to have guns within grabbing distance.

Standing in the sea? People on boats tend, usually, to be a little more responsible. Ad at below 50m, they will either have to be expecting it or be pretty fast at grabbing their guns - I doubt it will be in sight for more than perhaps 10 secs.

According to TFA,, it is specifically intended for times when the sea prohibits the normal boats; there is no reason to believe an RC boat would me more seaworthy.

According to TFA, it is continually monitored, if not actually flown, so they already have a human in the loop.

Only if there were positive discrimination. If there is no discrimination, employers would hire, or not hire, unqualified men in the same proportion as unqualified women,

Which would go the other way: of only the most determined stick to the workplace, they should be the best. That pressure would weed out underachievers, leaving a biased population of high achievers to be compared to men.

My point is that studies have allowed for this pressure, and have been conducted only amongst women who have not disqualified themselves. If you compare only women without children to men, men still get paid more for the same jobs.

This has been allowed for in the various studies of the subject. Even among childless women there is a significant discrepancy in salaries for similar jobs. Thoug, from one article in the Economist, the discrepancy almost disappears for childless women not in any relationship.

This, as has been pointed out, the discrepancy never flips the other way, as would be the case in a truly fair environment, In such an environment, necessarily finite studies should show results randomly either side of equality.

Which shows that the word is undefined. But I would expect, whatever the actual details, "hardcore" means unsuitable for broadcast TV. I would agree that GoT might be defined as porn, but is being broadcastable automatically makes it not hardcore. My definitions would not include anything transparently consensual as hardcore, but explicit portrayal of sex is porn. But the "hard" in "hardcore" implies some level of violence or coercion.

Anyway, I introduced the word into the conversation, and what I means was the sort of non-consensual violent porn which I think would be damaging to children. Whatever the words used, there are some extreme images which are capable of damaging children. While I accept that consenting adults should be able to access such stuff via moderately protected channels on the internet or similar, they should not, as the OP suggested, be transmitted free to air on any wavelengths the transmitter chooses, including those already in use for domestic TV. There is a need for a regulator of some sort - though the rulebook for that regulator is not obvious.

Of course. But the OP was suggesting people should be free to do whatever they wanted - which would include using bandwidth wastefully and overwhelmingly (i.e. at high power). Hence the need for some form of regulator to enforce the use of efficient modes, and power levels no more than necessary, not as the OP implied at complete liberty.

I agree that modern technology makes possible a greater variety and greater number of uses of the available bandwidth. All the more reason for a good regulator to share it efficiently

No, I would not describe reasonably consensual sex of the sort required to make children as /hardcore/ porn. Hardcore porn probably requires strange ustensils, use of bodily orifices in ways that do not lead to reproduction, often blood, pain or simulated pain, obvious coercion.

Children, not having yet developed the sexual drive, do not understand the motivation for sex. However, I do not think that seeing normal consensual sex, which I would describe a porn but not hardcore porn, would be seriously damaging to children. But the violence, simulated or real, common in hardcore porn is very frightening for children who do not understand the world but know that they are weak, uninformed and defenceless. I would ezpect it to be seriously traumatising for a majority of pre-pubescent children,

I never claimed more moral authority. I claimed my right to express my opinion on /. I also suggested that I am probably in the majority. That is not a moral statement, it is a personal view. No, I think the OP is a short sighted selfish git, but I do not see it as a political statement, just an ignorant one. That, also, is a personal opinion not a claim of moral superiority,

In, I don't need evidence for "Think if the children". As a parent, I think if the children. A purely emotional response, but one that I share with most of the human race. Which is how we got here - species that don't think of their children tend to go extinct, at least at our scale (insects etc do fine on lay 'em and leave 'em). It is one of my fundamental values, along with free speech and not being eaten.

And I think expecting small children to work out what is happening and take appropriate action when Bugs Bunny is sudsenly replace by sado-masochistic sex is to have totally a unreasonable understanding of what children can and cannot do, and betrays someone who, so far as children are concerned, does not know what they are talking about.

I entirely agree one should supervise children. Children should only be watching safe channels, and adults should supervise them. But your proposal is to invade the safe channel - to replace Cartoon Network with snuff movies. This is not putting porn where the unsupervised can find it, this is forcing porn into areas where reasonable people would not expect to find it.

It is not "children might", it is "you are forcing on children". The difference between consensual sex and rape, the difference between guns in self defence and firing at random in a shopping mall.
