Wow... chill. Nobody's saying that entanglement allows instantaneous information transfer. The way this works is (roughly) that we send some photons using a recorded polarisation, the receiver sets up some polarising filters at random and then both parties communicate the results using standard (non-FTL) communication channels. The quantum magic happens because an eavesdropper can't know both the initial polarisation and the polarisation setting at the detector and any attempt to "copy" the photon in flight has at least a 50/50 chance of getting the polarisation wrong (assuming only two polarisation settings), thus alerting Alice and Bob to Eve's presence.
The whole system (from emitter to detector) is the quantum entanglement "experiment", so it's easy to see how an eavesdropper will prematurely collapse the probability waveform, ruining the values that Bob sees. But again, even though in normal operation, without an eavesdropper, the collapse is instantaneous with the measurement at the detector end, Alice and Bob still need to communicate their results before they actually know what that measurement means, so there's no FTL information transfer... so it's actually not Hokum.

Re: Any rope is the problem
That massive amount of current needed to shift an elevator car ends up producing immense amounts of heat
Well if there's that much hot air, why not tether a hot air balloon to the lift and use that to lift the cargo? You'd have to have the balloon "outside the box" (ie the building) which would definitely lead to challenges on windy days, but at least you might be able to use other waste heat from the building to keep it topped up. Sounds much nicer if you take the gondola to the 50th floor instead of a regular old "lift".

Re: Phew! I'm safe...
It's called steganography. Nothing to see here, move along now.
I haven't read the paper, but I don't think it's stego. According to the article, such inputs are used to trigger an existing infection rather than being used as a carrier for code or new information beyond the "trigger me now" signal. In this case, it's probably just another example of the use of "oblivious agents": an "agent" continuously monitors whatever sensor data it has available, produces a hash of some kind and if the hash matches a trigger condition, it activates. The "oblivious" part is that the agent doesn't "know" in advance (and examining the code won't reveal) what specific combination of inputs are needed for it to activate which function.
Re: No Brainer
To prove it's fusion you need to see what is in the box.
Not necessarily. If you seal the apparatus up and you have a really accurate scales (or a long enough time scale) to measure the mass of the thing, you should see a gradual reduction in mass. That would probably be enough to prove there's fusion going on. Or fission, but we have to take it at their word that there aren't any fissile materials in the box providing the extra energy output.

Re: Yes, that will work well.
Just use Beethoven's First Movement.
Ah, yes... his little-known "Meconium".
There's a phrase in Japanese (see title) that literally means "word-processor idiot". It refers to a problem that people are becoming less and less proficient at actually writing Kanji. The way this works on computer, people type in the words phonetically and then it gives them a choice of possible kanji. So while you still need to be able to recognise what the correct kanji is/are, it's actually deleterious to your ability to write those kanji from memory.
Although it's not as extreme a problem in English, I think this push to downgrade the importance of (hand-)written language in favour of typing things on a computer does have similar consequences. It's not exactly that handwriting itself is that big a deal, but I think that things like auto-completion and automatic spell-checking tend to make people lazy when it comes to learning how to spell things correctly and how to distinguish between homonyms like "their" and "they're". A spell-checker alone can't help you learn these things, and most grammar checkers aren't really up to snuff.

Re: airplane mode
Hunting for a cell tower signal is a *receive* function ... There's nothing imperfect at all with the details of the implementation ... Androud devices ... take elaborate measures to work around this flawed implementation
Point 1: "The MS (ie, the phone) will send a Channel Request message to the BSS on the RACH."
Cell registration is an active process, requiring the cellphone to actively transmit. If you're looking for an excuse to bash Android devices, at least try to base it on facts: even if a phone can "hear" a base station, it still needs to transmit to register with it, regardless of whether you've got an Apple or Android or MS or Blackberry or whatever.

Re: I've got a top tip for all you pound a day guys who are smokers too...
Fags do suppress the appetite so it could be an aide to staving off the hunger
You'd be better off getting some garlic and rubbing a bit in your mouth. Apparently it's good at staving off the hunger.
Some other thoughts...
Various people have mentioned potatoes and rice, which is a great idea. You do need to make sure you're getting some protein, though, Dried beans, lentils and split peas are the best value, along with TVP (textured vegetable protein). Oils and fats will probably be your most expensive outlay.
Someone else mentioned foraging, but it's not practical if you're either living in the city or don't know what you're looking for out in the country. It also tends to be seasonal, but if you know what you're looking for you can get plenty of fruit and maybe mushrooms (requires knowledge and caution!) and definitely some plants like wild garlic and even dandelion or nettle that are easily identified and easy to find.
In the city, foraging is pretty hard. You could follow a squirrel back to its lair and steal his nuts, I suppose. Much easier is to find a supermarket where they're offering free samples of stuff. You could steal a copy of "Steal this Book" and get some ideas for other ways to get free stuff, or invite some friends around for some "stone soup" (you provide the stone).
Surviving on £1 a day sounds very hard, unless you "cheat" by relying on getting free stuff (like sugar and ketchup packs and butter pats from restaurants). As an awareness-raising exercise, though, I'd have to applaud it. Good luck with it!

Re: There is a helluva lot of difference
As soon as they start decelerating at the other end, they'll get a column of exhaust catching up, and smashing into them!
No. First, you have to understand inertial frames of reference. If I'm on the roof of train and I fire a gun in the forward direction, it will have the same apparent velocity (to me, and ignoring air resistance) as a bullet fired in the "backwards" direction. Despite being in motion, the relative velocities still work out the same as if we decide that (or it's actually the case that) the train is fixed in space. This is our "inertial frame of reference". Second, you need to take into account Newton's third law: "for every action there is an equal and opposite reaction", which is the principle behind any "reaction drive", of which this is an example. Again, consider the plasma exhaust coming out of our "gun". It has a mass that is a tiny fraction of the mass of the ship, but will have a large acceleration. Since F = ma (force = mass x acceleration) and due to Newton's third law, our ship will have a balancing (reaction) force propelling it in the opposite direction to the plasma. Since the ship's mass is so many times larger than the projectile, the resulting deceleration will be much less than that experienced by the projectile.
So in summary, (1) the projectile will always accelerate away from the ship, regardless of which direction we're going, and (2) catching up with the exhaust assumes you're going forward-backward-forward for some reason, rather than forward-backward, and even then, the chance of hitting the exhaust over such vast distances is crazily small. Also, (3) detonating the pellet and turning it into plasma means that after a short time there won't be anything except a diffuse gas for anything (including other ships in the vicinity) to collide with anyway.

Re: Form factor is nice...
Speaking of form factor, the first thing I noticed about this is that the power switch is on the top. That's either a design flaw, or perhaps a tacit admission that the heat output of these is such that stacking multiple units would tend to cause overheating. IF these things were cheap enough to use in a small cluster (and if it weren't crippled by only having USB 2) then I'd have thought being stackable would be a virtual necessity. I note that neither the Mac Mini nor the Chrome boxes have power switches on the top. I don't know if they have heat dissipation problems if stacked, but at least the power button placement doesn't stop you from trying it out.
Re: @Rampant Spaniel: Rights
While logically, a refusal to answer a question would imply guilt ...
No, it doesn't: not logically or legally. Previous posters have already covered what valid inferences (note: "to infer" rather than "imply") can be drawn from refusal to comment in criminal vs civil suits, so I've nothing to add. In terms of logic, though, it's obvious that no firm inference can or should be made from such a refusal to comment. Various logical possibilities exist, ranging from hiding one's guilt, protecting another guilty party or avoiding incriminating oneself for a different crime than the one being examined, the belief that the question need not be answered (for whatever reason), avoiding revealing something that is embarrassing (though not illegal, such as having an affair, being the subject of blackmail or whatever), simply not understanding the question or being incompetent, or believing that the question is unfair and best not answered ("so have you stopped beating up your wife?"). Logically speaking, a refusal to speak doesn't lend any weight to any of these (or other) possibilities being correct.
Apart from that, most of what you said was fair enough. It's just a pet peeve of mine when people talk about logic in a clearly illogical way. That, and mixing up "imply" and "infer"...

Re: Of course it's a German invention
Germany already produced films of cats in the 1970s
And Japan had its famous autocatography 『吾輩は猫である』 ("I am a Cat") back in 1906. This fascination has obviously been going on for quite a while, so it's unsurprising that modern humans are still in thrall to the cat.

Re: Clever people make. Clever people break!
My first thought exactly, though I see it more like a crowd-sourcing thing more than an algorithmic thing: a "network" provides data on where these dynamic-or pre-existing-product placements are, and your player filters them out and replaces them with "Acme" or something nondescript.
[Beer icon] of course some things are better left un-messed with. I'm off to rewatch "Ice Cold in Alex" ... Worth waiting for.
Re: More parallel instead of 100X
but ray-tracing is THE easiest thing to convert to parallel as each pixel is independant.
It may be the easiest to make it work in parallel, but it won't be the most efficient since you need to access colour info from all over the scene. Memory will be the bottleneck, in other words, not computing power. Rendering fractals, on the other hand would be an application where pixels are truly independent.
Re: Good headline
And then there was also that Bulwer-Lytton competition runner-up from 2010 (Detective category), which is what immediately sprang to my mind:
As Holmes, who had a nose for danger, quietly fingered the bloody knife and eyed the various body parts strewn along the dark, deserted highway, he placed his ear to the ground and, with his heart in his throat, silently mouthed to his companion, "Arm yourself, Watson, there is an evil hand a foot ahead."
I think it even got read out on Countdown. Make of that what you will :)
As I was reading this (chuckling along the way) I glanced down to see how much more there was to read, finding only a few more inches to go with no "next page" link. I was worried that the ending was going to be unsatisfactory given the scant few lines remaining. However, I was not disappointed! Top episode--Chin-chin!

"Apple sold 22.9 million iPads"
Wouldn't the Samsung ARM Chromebook be a better thing to compare it with? OK, maybe not, considering that it doesn't have touch, but it's more comparable in other ways, IMO, most notably in the sense of being a laptop replacement/adjunct (with keyboard) and having a more "niche" OS (if you accept that Win 8 RT is different from "proper" Win8). Does the Reg have any figures for sales of these ARM Chromebooks for comparison?
Can this reactor design burn thorium fuel too?
It doesn't sound too dissimilar to other Thorium-based molten salt reactors I've read about (including the fail-safe "plug" that melts and has the salts draining away into several sub-critically sized reservoirs), so I'm guessing yes. As I understand it, though, the fuel cycle for Thorium would have to include elements outside the actual reactor, for chemical separation of various waste (or "poison") isotopes that would get in the way of a self-sustaining reaction, and possibly other similar steps (for maintaining other ratios of elements). Someone here once pointed out that the chemical separation process is pretty nasty (dangerous) based on the need to use (iirc) fluorine. Apart from that, in a Thorium reactor, the main "fuel" is actually Uranium, which is a decay product of Thorium, so there shouldn't be that much difference in the reactor design.

Re: File? What file? I don't remember saving any files!
With such tiny tapes I can only imagine that alignment was a real pain.
At least they had the good sense to only store one track on the tape rather than go with the idea of basing it on 8-track (or similar) recording format. If alignment with just one head is a problem, imagine how bad it would have been with multiple tracks/heads.
you had to use pokes to do anything remotely interesting with the sound and graphics instead of high level calls like Sinclair BASIC
But on the other hand, the manual that came with the C64 was pretty good and included lists of addresses to peek/poke for changing colours, using sprites and making music/sounds with the SID chip. There really wasn't a need for extraneous syntactic sugar within the BASIC interpreter when the peek/poke addresses were documented. The more complete "Commodore 64 Programmer's Reference Guide" even included schematics for the C64 itself along with a wealth of other technical info such as for accessing bank-switched RAM, a full memory map and even tables listing the frequencies in Hertz of standard musical notes and trig identities. It also had a pretty decent introduction to writing assembly on the 6510.
That document probably ranks as being the best technical manual for any computer I've ever used, even to this day. They just don't write manuals like that any more, unfortunately. I've still got two copies of it floating around :)
