Brute-forcing terminating even the most carefully-crafted object-orientated library is a recipe for a pile up. (Say, Bugs, wasn't that a realloc call you interrupted?) After that sigalarm had been raised, the only sane action would be to cross your fingers, pray hard, log the condition, print an error message, and exit swiftly.
But yay! for perl on El Reg. More please.
>>On what basis a computer could discern an independent attack plan from the above is beyond me<<
Any sort of digital signing; something as crackable as:
if ( md5( fire_plan.coordinates + pentagon_secret_key ) != fire_plan.checksum ) printf( "bog off\n" );
That said, I really hope we have independent control of our nukes.
These days I can stomach "Web 2.0" as a phrase. After all, we need a term for all the AJAX flummery which fascinates real users. But these twits are earnestly talking about "Web 3.0".
Web 3.0? Web 3.0?! WEB THREE POINT BLOODY ZERO! I just put the term into Google. OMFG.
(Sorry that turned into a rant. But I needed to get it off my chest.)
Good work, Andrew. Keep it up. These people are supposed to be the cream of our intellectuals; if they don't have the backbone to condemn the linguistic slush Verity uncovered then they shouldn't be teaching. And while we might not be able to catch all these jobsworth academics, maybe the efforts of the fourth estate can make them think twice. Critical thinking? My arse!
From the report "a pair of protons in the LHC will release an amount of energy comparable to that of two colliding mosquitos"
Henceforth can El Reg give all energy measurements in units of "colliding mosquitos"; e.g. "To solve our climate problems, wind turbines would have to produce the energy equivalent to 20-billion collidng mosquitos..."
...the report /also/ says,
"...the rate at which [black hole] absorption would take place would be so slow if there are seven or more dimensions that Earth would survive for billions of years before any harm befell it."
Hang on a minute, hasn't the Earth been around for about 4.5 billion years?

1) Any alien observer will see the change in the sun's brightness - rather than the signal itself. (This is how we detect extrasolar planets at present.)
2) This would be a /helluva/ lot more powerful (i.e. "brighter") than the delicate Radio signals we're currently broadcasting. Plus an optical signal wouldn't be turned to mush by dispersion or swamped by the vast amounts of RF the sun naturally "broadcasts".
3) The lizard army is already on route, so what's the point?
4) It was in New Scientist.
A server with access to a cleartext secret can send a "challenge" and demand the client provide a hash of the challenge + secret to login, preventing the transmission of the password over an unencrypted connection. This is used, for example, by the APOP command of pop3. (And if that sounds rudimentary, Outlook doesn't even bother to do this - it just sends it as plaintext.)
But to do that, the server needs access to an unencrypted password. Even if you use encryption on the password file (properly salted, to prevent the use of rainbow tables) then chances are anyone who can get at the password file can get at the master key and decrypt them.
"Also, so that I actually learn something from El Reg, could someone please explain the Swarzschild radius in layman English?"
Its where the escape velocity matches the speed of light - i.e. the event horizon of a black hole. Once you're within the Schrwazchild radius not even light can escape, and you ain't never coming out. (And any object smaller than its Schwarzschild radius must a black hole.)
SMALLPRINT: it applies only to non-rotating, uncharged, spherically symmetric mass distributions as modelled by general relativity. The value of the Schwarzschild radius may go down as well as up.
We've got a new postman, and everyday seems to bring another piece of misdelivered mail. One last week felt like a bank card. (It was in a "discreet" plain envelope that just shouted "bank".) And presumably there are human beings, aside from the postie and unintended recipients, who have access to snail mail and could pinch, say, 0.05% of that being delivered to Equifax. (And if they're really smart thieves, then, after reading it, they'll put it in a new envelope and add it to the next day's post. Who would know?) I'm probably wrong on the details, but I'm sure its possible for rogue employees to read snail mail.
Is the risk greater than that of a plaintext email be snarfed by someone at an ISP? I can't quantify either. Certainly it's happened. But my emails rarely pass through a dozen SMTP relays (NOT HUNDREDS). And separating the genuine missives from the spam seems beyond human ingenuity. Finding this stuff at the packet level, would be even more impressive - particularly if its a jpeg of a credit card. Surely there are easier ways to get ill gotten gains from the web?
That said, I'd won't be trusting my financial details to an unencrypted connection any time soon. But maybe that's down to my faith in tin-foil millinery. ;-)
You don't need to refresh the DRAM if the memory’s not being used. The trick would be figuring out which memory is unused, or could be swapped out to save power. Since memory controllers are (becoming) integrated into the processors, that's not so infeasible. (And of course, libc needs to be capable of deallocating core when pages in the heap become empy.)
And why shouldn't hard disks be capable of working at 50% speed? Why should they have to go flat out, every time I want to write a line to a logfile.
Went and found the paper (http://arxiv.org/abs/0712.2669) And they labelled _their_ pretty picture. In case its not obvious, the galaxies are the two (violet) blobs in the lower left corner; the blue wisp is the jet, having passed through the second (companion) galaxy.
BTW the authors believe the two galaxies are merging,not just orbiting. (And the companion’s orbiting "clockwise", since you don't ask.) They tentatively suggest that the merger may have cause the supermassive black holes at the centre of each galaxy to become (AGN).
"Would we be correct in thinking that traffic to your splendid registered-users-only consultation site has in the interim been in the high severals?"
How about a Freedom of Information Act request to find out? And while you're about it, throw in a few more telling questions - like, "How many people have registered?"

1/ THE LINK IN THIS ARTICLE to SPACEDAILY.COM IS 404
2/ Some of us like links to arXiv papers, so we can read them. We certainly expect the authors have read them. For the record, I think, the paper in question is:
3/ This article waffles where it should be explaining. The first page is not too bad, but the second is appalling.
I'd not heard of MOND before, and I had to go read about it on on wikipedia - just to make sense of this article. I still don't understand what the author means when he says "The outre model of spiral galaxies as cosmic Faraday motors, espoused by some theorists,". Which theory is this? (It's not the "mainstream" CDM, surely?) Which theorists are espousing it?
Dark matter is fascinating. There are lots of tantalisingly off-beat theories (try this http://arxiv.org/abs/hep-ph/0612286v2), and its a constantly shifting field where new evidence is accumulating all the time. This article doesn't come close to doing it--or science--justice. Please, no more articles like this.
I guess it was Friday and you didn't feel like doing any real work. Trouble is, now I'm gonna be disappointed if there aren't new icons every week. So here are my suggestions for a few more:
>> DUI – I've just got back from the pub, and mee liquid lunch is pressing heavily on mee median-pareital-temporal lobe, but that's not gonna inhbit mee from wading in with mee five-penneth worth...
>> Lexographical apoplexy – this article contains a word that needs banning/Hell I though we'd banned it and hung the author already.
>> Keeping abreast – the only thing that could have allowed the author to walk away unscathed from this wreck was a pair of fully inflated Bulgarian Airbags. And I didn't see them deployed.
>> "Why the hell hasn't the What's-the-IT-angle? icon got a picture of something computer related on it?" icon. – Self explanatory.
>> Incoming! – I was mentioned in this article and am going dispute points of fact with the author in a snarling hissy fit, so why don't y'all ready some popcorn and start a little pool on who's gonna win.
>> not a geek – despite working on a helpdesk, the only IT expertise I have is knowing where the off-button is. But I heard the site had some cool icons and Paris Hilton stories; c'mon guys, where are the Parish Hilton stories?
>> Orlowski is a God! – man, that Orlowski guy always says it as it is, and sure gives those blogging, Sadvillian, Web 2.0 badgers one in the eye. Down with Wikipedia! Down with Sadville! Down with Web 2.0!
>> Die, Orlowskie! Die! – I'm a wiki-fiddlling Web2.0 blogger who, despite being thirty-something, still lives with my parents. And I'd of rather been locked in a body bag with Orlowski's decomposing corpse for a year than read that crock of shit. Up with Wikipedia! Up with web 2.0! Up with Sadville! Up my giant, deflated furry member!
>> amanfrommars?! WTF! – hey guys, why the hell did this algortihm get the ultimate accolade of its own icon?
>> Deputised – Sherriff has skimped on the links again, so visit _here_ for [more] pretty pics and _here_ for maths that violate countless international treaties on torture. You have been warned.
They probably just can't get their kit in the gap. ;)
Actually, there's more to QM than Heisenberg. For example, the position of an electron in a Hydrogen Atom is unknowable, thanks to wave-particle duality and the need for its Energy etc.. to be quantised.
Plus evanescent waves are little buggers. For example, frustrated total internal reflection (which is what is being described in the article) is a form of "tunnelling" that can be modelled classically using Maxwell's equations without QM. And the PR link above claims the photon's *direction* is imaginary, which, if correct, would make it tough to pin them down.
I think someone's stolen my userid. I let it go when the name differed by case, but now someone's posting under my name, and kicking up a stink! This is why we need a bloody national ID card - to stop this kinda traversty (as well as to stop people registering cars with false details). So /peter/ hands off my nick - I got there first. ;)
The year I was born is the one piece of personal info I give accurately, since I can understand how it helps their marketing (hence income) and it's not overly personal. Of course, I block all the ads they throw at me based on it, but hey - life sucks.
This appears to be the press release (in Italian):
English translation provided here (as PDF):
This seems to be the paper about the same planet:
They were planning on integrating more data – so maybe its been revised before publication in Nature.
Anyway, based on the above, THE PLANET ORBITS at 1.7AU (about the distance of Mars), and HAS A MASS of at least 3.5 times that of Jupiter.
And for the record, a Red Giant doesn't exhaust *all* its Hyrdogen - just all that IN THE CORE, it then contracts, heats up, and begins fusing hydrogen in a shell around the core (now composed mainly of Helium) - try this link (with nice graphs):
