Much as I like cats, you really do not want a robot to be cat-like. Consider the difference with dogs when you throw a stick. The dog runs after it and collects it. The cat looks at you as if to say: "Hey, you threw it, you go get it." I consider this a clear indication of the more advanced intelligence of cats, as compared to dogs.
A simple rule of thumb is:
A dog has a master
A cat has house-mates
A Siamese cat has grooming staff
Re: Any rope is the problem
Enter the Heisenberg/Schrödinger elevator. It tunnels to the correct destination, and allows an arbitrary (but uncertain) number of elevators per shaft. Add defocused temporal perception and they will be there before you know you want them.
The only downside is their tendency to sulk in basements.
And there I was thinking that producing better, more competitive products was what capitalism was about!
Deary me, how naive of me.
Re: SCO ... do us all a favour . . .
Is their legal team run by Mr Slant?
Alternatively, SCO might really be a vampire outfit. Somebody spilled blood in the wrong place.

Re: Hang on
SKA does not really work with steerable dishes, it uses synthetic aperture based on many small antennae. By combining the signals from many sources with the right delays, you can form a vast number of beam shapes with a vast number of different side-lobes. This in principle allows you to let a telescope be blind in the direction of fixed radio sources. If you know terrestrial sources are a problem, you can in theory create a null-sensitivity for things on the horizon, or (more easily) in the specific direction of a particular source.
Source above the antennae which drift around and are difficult to predict are a pain, and a cause of many ruined pieces of data.
Re: Caveat Emptor
Well measured response. but I would like to add one more tiem:
8. Beware of injelititis: managers who have a combination of a large degree of incompetence and a similarly large degree of jealousy, a combination known as injelitance. Injelitant people in managerial roles cause a disease called injelitis. These people actually prefer to have a third-rate team, because they know deep down in their hearts they themselves are second-rate at best. Do not think you can single-handedly change the course of such a department (key words to watch: "Yes, mr. X is brilliant, but mr. Y is more sound"). Abandon such departments at warp speed.

The classic random walk is exemplified by a person (typically male) who is so drunk that at each step he cannot remember which direction the last one was going.
By saturating the senses with loud noise, combined with the usual quantities of alcohol involved, I would expect that those involved in mosh pits have a similar level of randomness in their motion, especially when adding collisions with other "particles."

Having plans in place is not a problem
Running around like a headless chicken when the proverbial shit hits the fan is. So yes, it makes sense to have plans in case war breaks out.
Thus, I do not find it at all surprising that there are plans in place for both defensive and offensive action. What is a problem is their constant data gathering on everything. Adding more data to a pool indiscriminately is like wall-of-death fishing: you catch and kill all sorts of stuff you did not intend to. I also do not buy the argument that they have "advanced data-mining algorithms". Data mining is a fancy word for pattern recognition in big data. To stay in the parlance of mining, let data be the ore, and information be the metal you want to extract. As the percentage of metal in the ore becomes lower, it makes less and less sense to extract the ore from the ground in the first place, unless the metal is very very precious. Even then, it is possible to be sidetracked by things that look like the metal, but aren't. Fool's gold (iron pyrite) springs to mind.
Likewise, if you gather data about everybody, looking for a minute percentage of people that actually hate the US sufficiently to do it real harm, the chances are false positive rates will skyrocket. This is a very real danger. It is much better to gather information in a far more directed manner, instead of implicitly suspecting everybody of ill will (which in itself seems to be a self-fulfilling mode of action).
As I have said over and over again: adding hay does not make finding needles easier. In mining parlance, there may be gold in them there hills, but it is better to drive a well-chosen shaft than indiscriminately removing the whole range of hills from the face of the earth, and sifting through tons of worthless rubble.
Given that the earlier leaks were about the far more dangerous data snooping, a cynic (who? me?!), might think this leak is there to distract from the more dangerous issues.
Are you sure it doesn't translate to Skynet?
Mine is the leather jacket
Somehow this reminds me of my parents in law, who (after a career teaching mentally less agile people, to put it mildly) were used to settle every argument by the application of equal parts of authoritarianism and volume (they still go at it hammer and tongs at each other, producing Pythonesque near infinite loops of "Yes it is! No it isn't!") .
They found out the hard way that this did not work on a scientist with a voice that some have compared to Brian Blessed in full spate (but only when I talk enthusiastically about anything or am just plain angry).
Maybe NASA needs to get in touch with the IAU from time to time.

The duration of the trek has everything to do with not allowing a robot to cheerfully drive itself off a cliff. Besides, if the engineering quality of Curiosity is anywhere near as good as that of Spirit and Opportunity (remember their "three month" missions?), Curiosity has time on its side. It's no Scott against Amundsen race to the pole.

Re: Non-Dutch people speaking Dutch
Ik ben een Brit in Nederland en ik heb geen enkel probleem hiermee, maar ik ben er dan ook geboren.
The Dutch have their own way of creating massive words:

might top that with 9 (jury still out on whether this word is OK. Trust the Welsh to come up with place names that (appear) to consist only of consonants:

Mr Eisenberg, are you certain you want to name your son Hagai? You realize you are dooming him to a career of quantum physics?
Re: you guys are just arguing...
A real scientist will go on arguing until he or she is satisfied by the proofs/arguments given (and even then could start arguing again as new data become available).
Dead right. Imagine the excitement if the fluid turned out to be alcohol (how easy would it be to get volunteers for a trip to Mars then?).
Alternatively, it was octane, and some Martian equivalent of the Humvee became so popular that they used every last drop (hence the carbon-dioxide atmosphere).
@Parax Re: they are doing it all wrong!
There's a Dutch saying which translates to:

I think this is most appropriate.
I am also reminded of Harry Enfield's perennial

Re: Codec patents
The difference is actually made in patent law in most countries.
Most patent laws explicitly exclude patenting mathematical equations (though not necessarily their application). Because any algorithm can be expressed in lambda calculus, it could be (and has been) argued that algorithms should not be patentable. Their application (as e.g. as codec) could be under various laws.
So, as Mr. Slant would say: "This is an interesting case."
With degree of interest being defined as proportional to the amount of money it brings to lawyers.
I had a version of this, but it quantum-tunnelled away

Re: If only..
Stewing the results in beer is recommended
They seem to be getting better very slowly. I have yet to see a real killer app for these, but maybe one will come along.
I will just stick with my current watch. I only ever buy a watch when the previous one breaks in such a way that repair is no longer economical. Given that my current (only my third) watch is a year old, and on average, my watches last about 19 years (OK, N=2 statistics), there could be some really enticing options available when I am up for my fourth watch.

Tonight I think I might be serving some portions of monkfish fillet, lightly drizzled in olive oil and some lemon juice, sprinkled with pepper and some fresh sage from the garden, wrapped in lean smoky bacon, baked in the oven at 220 C for just 15 minutes served with pasta and pesto alla genovese, and spinach.
Alternatively, I might just have some pizza. Some beer or wine would go down a treat as well
Pity really, I liked my HTC Desire a lot. I now have a Desire X (in part because the interface was familiar, in part because I got a good deal), but when that needs replacement I may well have to look elsewhere, unless by then telcos are dumping their HTC phones as they too bail out (something tells me living in the Netherlands has influenced me ;-) ).
Re: The key to teaching is the teacher
One thing that the government here in the Netherlands might try (maybe the same elsewhere), is to let teachers teach, not administrate. I gave a few lessons of computer science at schools nearby, to show kids that CS is certainly not learning to work in MS-Office. I was appalled at how much time teachers have to waste on administration during each lesson. And then there are the endless assessments and test that are foisted upon school children here from the age of 4 upwards. Endless assessments to measure outcomes. As one teacher pointedly stated: "A pig doesn't get fatter by weighing it more often". This tendency to measure everything to death has even reached preschool creches we have. I have heard people agonize about the fact that a 3 or 4 year old kid only recognized 4 letters whereas they should know 5 at that age. As if that difference is at all meaningful!.
When teachers are assessed by the teaching outcomes of their pupils, they will train them to perform well at the test, which is not the same as giving them understanding of the subject matter (let alone stimulating them).

Never? You mean only when they wrench it out of your cold dead hands. In which case you will be passed caring.
Let's talk photon counts and well sizes
Cramming 41Mpixel into such a small format is apparently possible, but only by making the photosites tiny. This means the electron well can only hold comparatively few electrons before saturating. This in turn means that the number of photons detected before saturation is low, which means increased noise and lower dynamic range. By binning multiple photosites together into a much smaller number of pixels, you can counteract this, and no doubt produce some very nifty 8MP images (especially with good processing techniques).
However, this will never match the quality of a DLSR, simply because the much bigger lens of a DLSR gathers more photons, which means better signal to noise. The reason is that quantum efficiencies (percentage of photons detected) of photosites are very high indeed (40% and above) so little can be gained there (and every gain at the phone end can be made equally at the DSLR end). A DSLR lens easily has 4x the diameter of that of a camera phone, meaning it gets 16x the number of photons. A phone sensor would need to collect 800% of all photons (which is clearly impossible) to match a DSLR sensor with 50% quantum efficiency.
So, will these cameras produce nice images, good enough for most purposes? Even when deducting marketing speak: yes. Will they match professional DSLR kit: No; this little thing called physics gets in the way. On the other hand, do I carry a phone with me all day? Certainly. Do I carry several kilogrammes of DSLR kit around all the time? No way!
