Uncertainty about quantum computing?
Well, it's quantum, innit?
Just got a message from Vodafone
saying how nice it was of them to decrease roaming charges.
I smiled and thought how nice it was that somebody (Steely Neelie, I think) in the EU is forcing to do so.

Is it just me
Or are these researchers just begging for an Ig Nobel Prize?
Absolutely! I grew up in the Apollo era, and as a seven-year-old nagged my parent's (successfully) to see the first moon landing in the middle of the night. Astronauts and cosmonauts were heroes that transcended national boundaries. They showed us we could reach beyond Earth. Almost every boy in my class wanted to follow Gagarin and Armstrong. I consider that a rather better aim in life than to become filthy rich in finance. If astronauts inspire a next generation of kids to reset their ambitions and aim for the stars (literally, not in the X-factor sense) it is money well spent.

Search as primary means of navigation?
The primary gets up my nose quickly. I may be old-fashioned, but I prefer remembering where I left things, and simply moving directly to the right location (cd under linux, or multiple clicks in windows explorer). If I forget, I just use find/grep in linux, and search when on windows (after berating myself for forgetting ;-) ).
I find hiding the "complexity" of a file system from me just annoys me. Others may like it of course.

I remember following its launch

If we cannot find an ideal planet, maybe the Magratheans can build one to our spec?
Re: UTF-8 alternative
Just using a different fixed font encoding is identical to using using the oldest cypher in the book: simple substitution. You can easily simulate the enigma machine on your PC, and that is much better than the proposed solution. However, note that fairly old computer machinery could already crack that (with the help of some nifty linguistic trickery and a few coding blunders of the Germans)
One-time pads do a rather better job, and are easily accessible (though harder to distribute).
A Norwegian blue?
Sorry, couldn't resist
Re: scare tactic
If you can get your hands on a good one-time pad (least significant pits of camera noise will do) you have a provably safe encryption, because the (truly random) key is as long as the message. Quantum computing does not help one jot. Trying all keys gives you (apart from a load of rubbish) all possible plain-text messages of the given length, and all possible zip/rar/tgz/bz2/... files of the same length, exploding the possible space of intelligible solutions further. Somewhere in that humongous space of solutions is the right one, but you have no way of telling which one is correct.
The only problem is transmitting the key over a secure channel. That is not that difficult: store these random bits steganographically on a DVD or Blu-Ray disc containing footage of the kids playing, and take them personally to the intended person when visiting them on holidays.
Any image (large) might contain some subtly hidden message (just replace the least significant bits of the image with bits from a compressed, encrypted file). Even this crude method can be very hard to detect, as a compressed file is already close to noise in its bit patterns (high entropy signal). Any high entropy signal can be considered suspect for that reason (photon-noise-limited astronomical images spring to mind)
The NSA are of course aware of steganography, and could use this to suggest any media file is suspect. The only problem they then face is tracking all such data.

Re: "practical applications be drawn from it"
Not necessarily, I am afraid.
The part where Hitler loses is not in Mein Kampf, that part is found in books on history, but I doubt any self-respecting loony dictator would allow mere historical facts to get in the way of a megalomaniacal plan. It is more likely he will be thinking (word used without prejudice) along the lines of "If only good old Adolf had waited till he had the bomb, like I have done".
Re: World's cleverest company states the obvious
Evidently, they did not read C. Northcote Parkinson's chapter "The Short List" in Parkinson's Law. It tells you exactly how to weed out unsuitable candidates, and he presents an algorithm which gets you just one applicant (the right one) obviating the need for an interview.
I find it odd they did not find that paper, as it must have been scanned by them, and a quick google got me this.
At Google, unlike the X-Files, the truth is in there.
In both cases, it is a matter of finding things
An overhaul/replacement of LinPack is long overdue
Even the conjugate gradient benchmark, while very useful, does not say it all. Conjugate gradient problems are present in many optimization methods, but not in combinatorial optimization. Maybe an additional benchmark is needed for that. Some image and signal processing problems are not easily cast into an optimization framework at all, for these we would love to have a better benchmark.

DIBOL, short for DIABOLIC ?
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 . . .

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.
