No, the "ALTER DATABASE BEGIN BACKUP" was just how the issue was first discovered. The issue is that someone with *low* privileges on an obscure, minor DB server can bump the SCN on that server, which if it happens to be linked to any other servers (like your big important one), causes the SCN to get bumped on those servers. So you can DoS all the other servers.
So got a list of really significant stuff in the A380 other than the size and record amount of cabling?
Well, the A380 was the first civil airliner to really use composites. It has >20%, whereas prior to that it was 10%. See "Advanced materials" on the A380 wikipedia page.
In case anyone was thinking that £12B is a lot for a database, what that money *actually* represents is providing a large chunk of
the NHS's IT infrastructure for the next 12 years; or £1B per year for the IT needs of an organisation with 1.4 million employees and an annual turnover of £100B. The central data spine (which is the bit suffering the biggest problems and delays) is only one aspect of the system: it includes everything from making X-rays digitally available, to providing the network connectivity to individual GPs. Much of this is already in place and happily working.
Say a cup of water is 0.25L, and its temperature is being raised from 20C to 100C. That requires 4200 x 0.25 x 80 = 84 kJ
Now lets be really pessimistic on the Google front. Suppose my search takes Google 1 second, and the search is distributed over ten 500W servers. That's 5 kJ expended. Lets double that to allow for the costs of spidering and indexing, and double again since the article mentions two searches per cup. Thats 20 kJ. Assume I spend a minute on my 30W laptop viewing the search results; thats another 2 kJ.
The article shows it being very slow compared to awk and sed for a pathological pattern specifically chosen to make backtracking NFAs like perl/python's look slower. The article has absolutely nothing to say about the relative performance for day-to-day patterns.
So no, usenet posting, in this case, did not get him arrested.
Incorrect. His usenet postings were one of the two things he was tried for. As it happens, the july cleared him of making bomb threats, but convicted him of interfering with a religion - ie standing on public ground outside the Scientology base, holding a placard stating "it's not a crime to think". He wasn't allowed to tell the jury what his placard said.
Also, his usenet posts were one of the major items of evidence used in the trial.
I still will never understand why the EU is so against Microsoft
Its nothing to do with that. Some companies went to the EU complaining that under EU law, Microsoft was a monopoly that was abusing its monopoly positition. The EU courts ruled in their favour and imposed conditions on Microsoft, which they have not complied with.
Speaking as the guy who got the refund, the woman on the phone was clearly offering me a Windows refund, while the credit note that turned up just listed it as "goodwill". Ie some lackey in a Dell office decided it would be easier to pay me some money than waste lots of time arguing. I doubt that Windows refunds are now official policy.
Still, I'd urge as many people as possible to try a similar approach - maybe it would then force Dell to make windows-less offerings (at a suitable price) in the first place.
Note also (although IANAL) that contracually they didn't have a leg to stand on - their T&Cs didn't say anything about returning the whole system, while the Windows EULA made a specific offer that I could return just it for a refund.
Speaking as the guy who got the refund, yes it was worth it, both financially and emotionally.
It took maybe half an hour to read through the licence bumf, take some screen shots and write a letter. For which I earned about $80.
Emotionally, I was doing something satisfying. Some people might find it satisfying to sit for several hours by a river with a fishing rod. I found it satisfying that, in some small way, I was attempting to rectify the almost unprecedented situation whereby a near-monopoly supplier still gets its fee even if you use its copmpetitor's product instead.
In case anyone isn't clear as to the significance of this, SCO have two main types of complaint: straightforward copyright violations ("ooh your honour, their errno.h looks just like ours"), and the more nebulous "methods and concepts". The judge has now thrown out most of the latter, which were always going to be the more complex to defend against. The literal copying is easy: "it's from the POSIX standard", "it's from the old System III code that Caldera put in the public domain" etc.
polygraphs are worthless pseudocience, whose only merit is in their ability to trick the
gullible into confessing. They can be trivially defeated, for example by tensing
your anal sphincter during the control questions (the ones where they try to get you to lie), in order to set a high baseline.
MS, after all, has provided the source code as the final and most authorative documentation
Which is a deeply cynical move, knowing full-well that OSS developers like the SAMBA team cannot look at that src code without risking later charges of copyright infringement.
For the Nth time: in response to all the inevitable "far cheaper than NASA" posts; this is not an orbital launch - it just goes up to the edge of space, then straight down again. And getting into orbit isn't just going that "little bit extra"; a spacecraft in low earth orbit has about 15 times the potential + kinetic energy of a spacecraft that is at the same height but is just at the top of a vertical up/down loop.
Speak for yourself. I only have 9 fingers, and of them, only 5 have useful fingerprints. Which is why I always have great amusement at immigration whenever I visit the US these days. "Please place your left index finger on the glass. Oh. Er, your left thumb then. Oh, you haven't got a left thumb. Well, your second finger then. Now your right index finger. Oh. Your right thumb - er no, make that your second finger - er okay, so perhaps your thumb after all". And because the pointless (*) DHS fingerprint system at immigration doesn't actually do anything useful, I go through the same rigamarole each time I enter.
(*) nearly as pointess as the questions on the green visa waiver form, eg "have you been involved in genocide between 1933 and 1945 in nazi germany?".
Next thing you know, they'll be allowed to take DNA samples from prisoners to attempt to "link" them to crime scenes
In the UK, they can take a DNA sample from an arrested suspect, and keep that data indefinitely even if the suspect is subsequently acquitted or not even charged. This has already been tested and found legal by the courts.
we did technically make it, so why can't we govern it?
Sigh. As has been pointed out ad-nauseum, this is a non-sequiteur. Should the US control the world's telephone system because AGB invented the telephone? Should us Brits control the world's railways because we invented the railway?
There's no problems with the way everything is set up now
Society follows a collection of rules in order to survive. Together these rules are called the law. When people break the rules, then they harm all of society.
So Rosa Parks refusing to give up her seat harmed all of society?
PS: no, I don't think the two cases are comparable - I'm just pointing out the dangers of generalisations.

Because unless you know what fried the primary controller, there's a good chance you'll just fry the back up controller too when turning it on.
Well, the Colossus wasn't "based on bomba technology", and was never used to crack Engima.
Now lets be really pessimistic on the Google front. Suppose my search takes Google 1 second, and the search is distributed over ten 500W servers. That's 5 kJ expended. Lets double that to allow for the costs of spidering and indexing, and double again since the article mentions two searches per cup. Thats 20 kJ.

So We have 84 kJ verses 22 kJ.
That should be $3.5M. A lot cheaper than students.
Sigh.

SCO are finished.

There is overwhelming evidence for common descent (macroevolution).

Probably explains why there are about 35 fatal shootings each year in the UK, and 11,000 in the US.
Dear US,
Please find enclosed an invoice for the following developments:
payment terms: 28 days.
Warm regards,
Europe

There's no problems with the way everything is set up now
Two words: Network Solutions. I rest my case...
But the shuttle can only achieve low earth orbit.
So Rosa Parks refusing to give up her seat harmed all of society?
