As another poster pointed out, it's just posturing for anyone to say they are going to shoot down the drones.

Not from the ground. From another drone. Don't even need to shoot, just get above it and drop something sufficiently nasty on its rotors. Collect the wreckage and sell what's salvageable...maybe even in your Amazon store.

I have one that can carry 2kg...

They're talking 25 kg / 55lbs pound load here, so you're off by more than an order of magnitude.

It is a complicated technology

Bicoin is a distributed double-entry bookkeeping ledger where transactions need to be signed by the crediting account's (secret) key. And Bitcoin is also the (imaginary) currency unit used in said ledger.

Seriously, there's nothing there anyone who knows even the basics of accounting wouldn't recognize. It's just wrapped in a high-tech packaging.

There you go, making sense again.

"These snooty scientists, what do they know?"

I was raised in a very poor family, one of the poorest in our city, but I have an IQ that's very high, and I always made good grades in school. I don't see the relationship between poverty and smaller brains, nor do I see the relationship between poverty and crime. Of course I was raised in a good family that wasn't trash.

"I'm very smart. I lifted myself up by my bootlaces. Anyone who doesn't is trash. Crime is done by criminals for for the evulz, and is thus not affected by economic circumstances."

Parental involvement makes more of a difference, and unmarried teens are simply not the best parents. Ask any teacher and they can tell you which students have parents who care.

"Teens having sex is bad. Children doing badly at schools is caused by parents not caring rather than working two full-time jobs to make ends meet."

Congratulations, I think you hit almost all popular right-wing talking points. All that's missing is some scaremongering about immigrants. Maybe you could work that into the bit about crime?

I have a serious problem with gay marriage, as marriage is a religious ceremony, so the state should stay out of it. Civil union is the state sponsored joining, and should be the proper avenue for the state to allow something that religion indicates is wrong.

The problem is, the state can't recognize marraige without defining it. If you agree that the religious ceremony has no legal significance (that is, married couples also need to get a civil union if they want the state to respect their union), then fine; but if you want your marriage ot mean anything to the state itself, the state can't avoid deciding what it considers a valid marriage - and then carrying the moral and legal responsibility for that decision, if it would happen to put citizens into different categories based on religious beliefs. Indeed, it would be forced to recognize an official religion that gets to choose.

So, the only way to get the state out of marriage is to go pure civil union route and ignore whatever religious or other ceremony anyone feels fit to add on their own time.

Sincerely I cannot understand how this is modded informative. There is absolutely no factual data that supports what you just said. Sure, the bible implies what you described, but well, it's the bible, and the day we'll start to take the bible as "factual data" in Slashdot will be the day logic gets shattered to pieces.

The Bible gives data about the behaviour of biblical characters that is factual in the context of how these characters, as described in the Bible, would behave in a given situation. The grandparent was modded informative for making one such analysis.

In other words, Bible is a factual description of the World of Bible, which may or may not resemble the World of Average Slashdotter or World of Average American in some important ways. The same is true of all literary descriptions, whether meant as factual in the context of WoAA or not.

Going all Rambo is a good way to threaten to reverse that momentum.

Cue the obvious conspiracy theory.

The problem is where do you draw the line?

Why is there a line to be drawn?

Photographer refuses to take photographs at a non-white wedding because of "religious" beliefs. Will take photos of any white ceremony.

And? Can the couple still get married? Can they find a photographer? Pretty sure they can. The photographer's bigotry does not pick anyone's pocket or break anyone's leg. It does not interfere with anyone's rights. Let him turn down paying customers and give opportunity to his competition, it's sort of a self-limiting problem.There is no need for any action here, any more than if a Catholic music composer accepts a commission from the diocese but doesn't accept a commission from the local synagogue (or from the Westborough Baptist Church).

Explain to us then the rational opposing position then. Explain to us the pro-discrimination position whereby we should be permitted to discrimination on the basis of race, gender, age, or even sexual orientation when none of those things should matter.

You seem to be under the mistaken impression that all things except what the state have decided are proper should be forbidden.

Yes, among enlightened people race, gender, age, or even sexual orientation should not matter. That does not imply that unenlightened people should be subject to criminal prosecution or lawsuits.

You should be permitted to discriminate in some areas because you should be permitted to do anything you want that does not interfere with the fundamental rights of others. Housing is a fundamental right, so you shouldn't be legally able to discriminate in renting out a house. But hiring a specific person to take your wedding pictures is not a fundamental right, so a photographer should be legally able to turn down a paying customer for whatever reason they want, even bigotry.

Doing the math with the wrong numbers isn't informative. You've ignored the atmospheric losses suffered by ground-based systems -- clouds, dust, the opacity of air. I think you're also being much more generous in estimating the potential lifetime of ground-based systems than space-based ones, which skews your numbers.

It may be that the gains are small enough to not justify the launch costs, though that depends on how much we value land taken up by solar arrays.

Chemical rocket engines dump heat into the exhaust gases but in a vacuum radiators have to be huge and heavy to get rid of significant amounts of heat from something like a nuclear reactor.

You could use a nuclear lightbulb style gas core reactor and either ablation or pure photon drive.

You are assuming we have to pander to pilots preferences. Just TELL them, "you will be videoed or alternatively you can choose another profession".

And some percentage of them will, which makes the available pool of pilots at a given price smaller, resulting in either lower quality or higher prices or both.

1. Door-locked status: Don't know, but you can't record everything -- there are already plenty of channels that are captured that are far more important

2. Streaming to ground: The NTSB has been working with other air safety bodies to make recommendations to do just that. One issue is available bandwidth: there just isn't enough of it available. So the amount of information that can be transmitted would be limited.

3. Floating black boxes: Like the downlink scenario, breakaway recorders that float are being looked into. More importantly, though, are better crash locator beacons, so the crash debris field can be found more quickly.

In the case of the FDR and CVR, that already happens, sort of. The devices are only able to handle a finite amount of data, and new data overwrites the old. So eventually you effectively get what you are suggesting by normal operation.

And there is a good reason not to dump the recordings. During an investigation of a crash where wake turbulence was suspected to be the main culprit, the investigators had the FDR of the plane ahead of the accident plane pulled to see just exactly where it was in relation to the accident plane. As I recall, the data showed the leading plane was much closer to the accident plane than anyone had suspected, and the wake turbulence would have thrown the accident plane around violently. WIthout the additional data, investigators would not have been able to confirm a hypothesis as to a contributor to the crash.

Could you elaborate on what you mean by "alter orbital structure and energy levels"?

I mean part of the electrostatic attraction between atomic nucleus and orbiting electrons should be countered by expansion of space between them, which in turn affects stable electron orbits. In fact all forces should get weaker with distance faster in an expanding space than in flat space.

Electromagnetic force is mediated by virtual photons, who's wavelength gets longer as space expands, thus sapping electromagnetism of some of its native strength and somewhat altering the lowest-energy point of all structures held together by it.
