V22 Tiltrotor drones with shrouded rotors would have better range, payload, and safety. You could still have several rotors mounted on multiple tilting wings. Wings provide lift much more efficiently than rotors do. Shrouded rotors could perhaps be made practically silent to those on the ground.

If a few motors failed, a tiltrotor could very likely fly back home to a runway on as few as one or two rotors. If it can't fly back home, the wings would often allow it to glide to a gentle landing instead of just falling out of control. The glide ratio would allow selection of emergency landing sites over a larger area under the point of failure.

The wings combined with a horizontal takeoff would allow a heavier payload if you can live without the ability to hover or ascend near landing. After dropping off the payload it would be lighter for a vertical takeoff, or it could get a rolling start on a driveway. A tilt rotor would be much faster and have much longer range. It could also pick up a fresh battery at an automated batery change runway half way to the destination. That would allow more range or greater payload. Though a regular quad rotor could do that as well.

If the government can't give it away then maybe auction it off. Don't auction off the copyright, just auction off a single copy. Then if it is GPL the goverment will have to fulfill its obligation and pay for what it got by posting the source code. Thus posting the source code for free will not be giving anything away, it will be paying a debt.

If no cellphone reception, set up a repeater on a nearby hiltop. Use a motion sensor on the road sending to hiltop repeater to get realtime tresspassing updates and give cops somebody to chase. Wifi with long range antennas will suffice for the first hop and maybe the second hop to a neighbor's internet connection, bypassing the need for a cellphone tranceiver. Some companies provide long range Wifi internet connections with range at least 10 miles, so you might want to check that out. They may give you a discount if it is just for low bandwidth alarm service.

Maybe put up a simple unlocked gate or just a chain with flags, to reduce alarms from harmless wandering tresspassers who will go down an open road but will not open a gate.

That TED talk only shows that religious birth rates were dropping similarly fast in the past. But there is a small religious minority who's birth rate still hasn't dropped, and barring legal reforms or some other limiting effect, simple evolutionary theory suggests they will dominate before long and bring the rate back up. And no, there is no significant limit to food production. It can be synthesized cheaply, in quantities only limited by the carbon content of earth's and other planet's crusts, from rocks, air, and nuclear or space solar power.

Care to back that up?

Converting all land areas and most or all of the oceans to maximum productivity crops would increase food production several fold. If that is not enough, then most of our dietary needs could be cheaply synthesised from rocks and air using nuclear or space solar power.

Luckily, religion is not a genetic disease.

I didn't mean to suggest that religion was a genetic disease. Note that I mentioned that the population would eventually be maxed out by secular parents as well. It is an evolution and culture issue not a dig against religion. Religious groups that encourage high birth rates might consider it a complement to hear it asserted that they will someday dominate the population.

Children born to the small minority of religious women who *continue* to have very high birth rates will eventually dominate the population of child bearing age. The birth rates of religious people have dropped over the previous decades, but certain high birthrate sects will rebound with a vengeance. Although high birthrate religious groups are much more common, population growth would also explode among secular persons who simply like to have more children, given a few extra decades. The process is faster within religious groups not just because of their doctrine but because they tend to mary within their group of higher birthrate spouses instead of mixing with outsiders of normal birthrate. But religion or not, the end result will still be higher birthrates until maximum capacity is reached.

The planet can easily support the food and space needs of several tens of billions in population, and the population will eventually grow to fill that capacity unless limited by law or some mechanism other than food shortage. As religious groups dedicated to high birthrates come to dominate the population, it may become increasingly difficult politically to enact reproduction limitations. Space of course provides unlimited expansion opportunities, and will become much more practical as reusable launch vehicles will have several decades of refinement by the time the planet is nearing capacity.

A digital cryptographic signature printed on a bill can be copied as easily as anything else. A private key hidden in a chip embedded in the bill would make it possible to verify the authenticity of a bill without communicating with headquarters, and could make it impossible to duplicate the bill without extracting the private key from deep within the chip. Unfortunately a chip for every bill would be a little expensive, and a resourceful attacker like North Korea could likely extract the secret keys from the chips.

If cash were eliminated it would be hard on criminals, but I doubt it would cut crime hugely. They could still use cash from other countries, cash they create themselves, precious metals, diamonds, barter, and possibly various attacks on electronic currency.

OpenNTPD was significantly more stable if I recompiled the kernel for pentium instead of 386. It was just a few milliseconds improvement in stability, but it was a clear difference. In the kernel config file there was simply a few consecutive lines labeled something like 386 486 586 686. I did nothing but commented out all but the 586 or 686 line and recompiled. This was about six years ago though, so I don't know if it's still an issue. I'm sorry I didn't subit a report back then. I meant to. Thanks for developing OpenNTPD.

The only lectures on Artificial Intelligence on Youtube are by Indian professors, but I couldn't understand them through the accent. With lectures on video, you could listen to the best lecturer in the country instead of some third rate professor. They can do a frequently asked questions list and update the lecture according to the questions. Electronic books can be both much shorter and longer. That is, if you can follow the quick example you can move on, if you can't, then you click a link for an expanded explanation.

So you admit that they stonewalled on the station list till 2008? And you admit that they didn't release their software until after they had been exposed by the climate gate email release? I may not have been clear, but I didn't mean to imply that they still haven't released stuff, but only that they were stonewalling at one time.

Jones PERSONALLY refused. The information about what data was used has been available since the original papers and research were performed! IT'S IN THE RESEARCH

Strange. Why didn't he just give the URL for the files instead of refusing. But of course you've quoted a source admitting he didn't release the station list till 2008. So it doesn't look like it was "IN THE RESEARCH".

You cite BEST as replication by some other than buddies, but I was referring to replication of the hockey stick. BEST did not replicate the hockey stick. Furthermore, BEST was lead by an alarmist, so that is not clearly replication by other than buddies.

when they are caught in their lies and ignorance, they NEVER, and I mean *NEVER* admit fault and accept what they were wrong about.

Anthony Watts admitted after his own study that the average temperature trend of the urban stations was no higher than the good rural stations. Of course he then minimized it and tried to make a seemingly insignificant issue of the difference between the trends in the diurnal temperature range. I see tons of ignorance on the skeptic side. The alarmist side actually seems to be much more grounded in facts. But now we're seeing that the alarmist facts may not be as solid as was once thought. And you simply dismissed my criticism of the attempt to "hide the decline", but you gave no reasoned defense. That is understandable given it appears to be indefensible.

I know how it sometimes seems hard to believe that your opponents can be so unreasonable. It starts to look like they are not being honest. Some oil company shills probably aren't. But I fully believe that there are many skeptics, even ones that have looked deeply into the evidence, who truly do not believe there is cause for alarm. You probably know that people can have an amazing ability to convince themselves of something. Some people also find it very painful to admit they were wrong, even to themselves. Unless the evidence against them is massively undeniable, they will not change their mind. And often, even if the evidence IS massively undeniable, they will not admit it. This cuts both ways of course. Back when we didn't know how much hiding was going on, many people adopted a conclusion, and are very reluctant to admit a mistake. It's especially hard for them to back off their conclusion because the evidence against the alarmist case is nowhere near overwhelming.

I don't think it matters anyway, because if the alarmists turn out to be right, there are a variety of relatively inexpensive ways to shade the planet and reliably bring the temperature under control. The really bad worst case scenarios are of negligible likelihood. It is impossible with available funds, and not an optimum allocation of resources, to spend trillions of dollars to prevent every disaster for which there is a tiny possibility. Those funds would probably be better spent preventing wars, plagues, cancer, poverty, or other things.

No. Those who requested the data requested that if all the data couldn't be provided, then the freely available data should be provided. They were refused. When asked for a list of what data was used, but not the data itself, they refused. Even if the data is available for free on the net, how can the results be replicated if they will not say which data was used?

>Mann's work has been vindicated and replicated time and time again...

It has only been replicated by his buddies. It's like a study by an oil company being replicated by another oil company. There can be no vindication for trying to "hide the decline". It is a well established rule of science that you don't leave out data that casts doubt on your conclusion.

You've fallen for their story. Many of us used to think the alarmists were good willed, and we assumed they were honest. I still think they are good willed, but we now know they are not honest. They hide important information that casts doubt on their theories. And worse, when their colleagues are caught doing corrupt science, their community maintains a code of silence or defends the indefensible. This casts doubt on all the evidence brought by the entire climate science community.
