Comment Re:IF.. (Score 1) 561

I think part of the problem is that what we think of as "intelligence" is a vector quantity and can't be well described by a scalar like IQ. You can define some metric on the vector intelligence, but that metric will be arbitrary. You can think of "intelligence" as a combination of memory, quick-thinking, spatial visualization, abstract mathematical ability, social abilities, etc etc. What combination of those are important will be different depending on what activity you are doing.

The particular problem here is that most people want intelligent companions in order to have interesting conversations. I don't think the standard IQ measurement is a good indicator of how interesting someone is to talk to.

I think most people just naturally find others with compatible ways of thinking. So using IQ to find companions who are also looking for high IQs may be pre-selecting for people who are not very good at socializing. Its not that high IQ makes you bad at socializing, but rather that if you are good at socializing, you won't need to use IQ to pre-select.

Comment Re:Military use of force (Score 1) 371

The lack of a formal declaration of war is one problem. The other is the idea of a "global" war on terrorism. In a conventional war, someone operating within an enemy country can be considered an enemy and is reasonable target for an attack. The geographic limits on targets put a limit on the ability of the US to simply execute citizens. An American citizen in an enemy country is a legitimate target of attack in the same way that (with some restrictions) anything else in that country is a valid target. However, military attacks when there is not a state of war with a country are normally not considered legal.

With this "global" war on terrorists, we are essentially saying that we can declare anyone anywhere to be an enemy, and then kill them. By this logic could China use a drone to kill an Chinese citizen in the US if they believe he holds a high position in Falun Gong? Could this argument be used to execute rather than arrest a US citizen IN the US if his capture was believed to be too dangerous?

It seems to be a dangerous blurring of the line between law enforcement and war.

That IS a major turning point. There is a huge difference between occasionally killing people in secret and declaring that the government has the right to kill citizens without a trial. Secret killings need to be limited in number or they can't be kept secret. Once execution without trials is in the open, what limits the numbers?

Comment Re:Yeah sure (Score 5, Insightful) 371

If you are in a state of war with a country, within some limits it is expected that you can kill people in that country. Where things get complicated is when you are in an ill defined state of hostility against a non-state organization like Al Qaeda. What are the rules on declaring someone to be part of that organization and there for a military target? While this question applies to any possible targets, it is especially troublesome when the target is an american citizen. The government cannot execute an american citizen without a trial. Can it declare an american citizen to be a member of a foreign military and then execute them? This would seem to completely bypass the constitutional right to a fair trial.

In a standard state-war it is fairly simple: If they are in an enemy country it is OK to kill them in the same way that it was OK to kill anyone else in that country. An american arrested for treason in the US on the other hand would get a trial. In a conventional state war you don't bomb countries that are not enemy states.

The level of activity to be considered a target for execution is also a tricky question. It is clearly OK to return fire if fired upon. When his actions are less direct it becomes more difficult.

At the root of all this is that the concept of "war" has changed and laws have not kept up with 21st century wars.

The technology development would be really valuable if you believe in a future for human presence in space (which I do, but which I admit is an almost religious belief). The actual asteroid capture on the other hand seems like a difficult but not particularly interesting stunt. 10M isn't really an asteroid, its a rock. Rocks that size hit the earth regularly.

Personally I'd rather see the solar-electric propulsion developed for large probes, especially an Europa lander / rover, and maybe a Titan lander or boat. The manned launch capability is fine if we are working toward a Mars mission (which I hope we are).

Manned space isn't about science and never was. Neither are the pyramids, the Olympics, National parks, fireworks displays, Christmas, Karaoke, or a huge variety of other things we spend tons of money doing. These things, like manned space flight, are more of a goal, rather than a means.

Comment Look for national lab salvage / surpluss (Score 2) 172

A number of labs like SLAC have a salvage department that collects old, but sometimes still functional equipment. If you are associated with an educational institution you might be able to get some of this stuff for free. It will be old but probably fine for some types or student experiments .

The difference between talking about something and doing it is the difference between amusing talk and a crime. We've also talked about putting bitcoin miners in all the high power FPGAs we use for real time feedback. The thing is that we DIDN'T.

As far as the penalty - this is like any other theft of materials. There must be applicable laws.

I think he was able to leave China because they didn't want him. They presumably had already extracted whatever information they could (if there was any). At that point he was just a liability. They didn't want to "cooperate" with the US, but at the same time didn't see any advantage in creating an incident. They had not reason not to let him go.

Russia presumably did want him in the hopes (true or not) that he had useful intelligence information with him. They probably decided that he made a useful political playing chip as well.

The US bungled this really badly. By to aggressively trying to retrieve Snowdon they made it clear that his allegations were largely true and attracted a huge amount of media attention. Something along the lines of "A low level NSA employee has defected to Russia. We can't comment on whether or not he had any sensitive information. He had been showing signs or stress recently. We are negotiating with the Russians for his return", followed by the traditional "no comment" on any of the issues Snowdon raised would probably have worked a lot better.

Of course even better would to not have had the NSA act in a way that if caught would do substantial damage to US interests .

Comment Re:Touch controls: NO! (Score 2) 148

Its not just cars - the F35 fighter plane has touch screen controls!

If you think manipulating a touch screen on a bumpy road is bad, imagine trying to do it while making 6-G turns in a fighter. In turbulence I sometimes have trouble hanging onto physical knobs on my 50 year old Beechcraft.

At SLAC we have installed real physical knobs to control the accelerator and they work. Operators can look at displays and have the tactile feedback of moving a control. It speeds up machine tuning.

Touch screens are a way to save money, but in most cases do not improve the user interface.

(Damn kids,, don't know how to design a UI like they did in my day....and the music they listen to.....grumble).

Is it a race between a Corvette and a Taurus, or is it a comparison of two different designs of battleships? I don't think the problem with the F35 is that it is a bad plane, but that it may not be a good weapon for 21st century wars.

  It might be a great weapon if China decides to invade Taiwan with thousand of troop ships, but that doesn't seem likely. Far more likely that China would use a combination of economic pressure, support of internal rebellions, cyber warfare, and possibly drones if they wanted control of Taiwan. Iraq has shown that while a technological advanced country can easily defeat the armed forces of a less advanced, less powerful country, the real difficulty is to actually extract any sort of lasting value from that victory.

Improved weapons would not have improve the US position in Iraq, Afghanistan, Syria, or the Ukraine. War is different in the 21st century.

Its not really an "asteroid", its a rock and not a very big one. We are talking about moving something the size of your living room, not a dinosaur-killer certainly not Ceres. . We have lots of fragments from meteors already.

Its OK, but it seems like a lot of work to move the entire rock here rather than just collect interesting samples and bring them back.

As the article said, it doesn't seem to really develop much interesting technology.

There is some Pt in asteroids, but no where near enough to pay for this type of effort.
