if all this data can be recovered in 3rd or 4th generation wipes... why can't they make a hard drive that exploits this to double its capacity ?
Because much of this is cross between urban myth and techno-babble, usually believed by people who don't really understand HD technology, basically the techno-phobic bureaucrat and Journalists.
Once the physical sector has been over written, it's been over-written and only the new data can be read, the old data on it is gone, gone for good. This is basic physics, magnetic polarity.
The problem occurs when re-writing a file, which is a written to a numbers of 'virtual' sector, actually called blocks. The actual physical sectors these block are written to varies and will typically change each time to those blocks at the front of the free space list.
Another issue is that when files are deleted, typically it is simply marked as deleted and added to the end of the free space list. Rewriting a file to a disk, typically marks the old version as deleted and makes another 'fresh' copy.
So the problem is that fragments, possible whole versions, of the old file are scattered over the disk, not 'under' the current sector.
Many years, ago when a 4.7Mhz IBM XT PC was state of the art, I was told to call new customer who had a problem printing, a hardware engineer had already called and the XT & Epson were fine. It must be a problem with the software, so I called the customer.
The first thing he did was claim the system is not working in 'output mode' " when I ask him to elaborate, he explains he was entering his customer details into the system & it was was working fine in 'I' mode, but as soon as tried 'O' mode to print the details out the system stopped working.
He kept refering to I and O modes, in relation to entering and printing details. I talked him through some tests of entering some details and trying to print them out. I explored every thing I could think of, he repeatedly reported there was no output, there did seem to be a problem printing. Unusual as we supplied a standardised system of software, XT and epson printer.
I decide to visit him in person, after all it was time out of the office, when I'm shown the PC, he's in a meeting and can't be with me. I start checking out the PC, quickly print some console output,its fine; I print a report from the application, it rattles out on the printer; it's all fine. I leave the report on his desk and head back. Now firstly remember at this time mobile phones are something out of science fiction movies. So when I get back to the office to find a message, it is still not working, he's been calling every 10 min's for the last hour demanding I return immediately, I do so without even stopping for a coffee.
On arrival, I'm certain every thing is OK, and it's user error, however he's livid, indeed purple with rage. I'm on tenderhooks, even though I know the system is fine, I need to find out what it is and diplomatically correct it, fat chance in his current mood. I ask me to demonstrate what he's doing. He enters some details, displays them on screen, everything is fine, so far. He then reaches round the right hand side of the PC, and flicks the bright orange button marked 'I' and 'O', I'm stunned for a moment, "NO!! DONT DO THAT!"I shout, but it's too late it's off.
It's the On/Off switch! instantly it all makes horrifying sense!
Moral: Take NOTHING for granted when doing end user support!
I could also tell you about the time I asked an end user to send me copies of their apparently corrupt back-up disks, and I received it by fax, but you simply wouldn't believe it:)
Whilst the Article was OK as a 'taster' it lacks the depth to be considered a practical comparison. All the examples coupled the content with the code, a big no-no in an industrial strength system.
Take the Java Servlet example, you only ever implement one Servlets in that way; Your first hello world Servlet. The problem is that it couples the content with presentation, something even the most light weight Servlets will avoid by implementing some form of Page Wrapper class to abstract the layout from the content. It also ignored JSP and/or using the Model-View Controller pattern.
Whilst I know Perl and PHP do suffer from this coupling problem, since the article does not do Java Servlets Justice, I am inclinded to believe the same is true for those too.

Surely we at slashdot are for the most part, capitalist and libertarian.
How can we be Capitalist AND Libertarian, this should be Capitalist OR Libertarian; they are actually different scales and are self contradictory concepts!
A Libertarian is by definition metrocratic (control by ability), this essentially the antithesis of a Capitalist, which is essentially plutocratic (control by the wealth).

Why have the Chinese authorities demanded an apology before releasing the US aircrew?
Experience & Common Sense tells me that a fighter pilot is more likely than a multi-engine pilot to be hot-dogging. So I think the US aircrew can show that they where not at fault (possibly with a Flight Data Recorder, but probably by just their accounts).
The Chinese are demanding the apology because they know that is what the rest of the world will remember not the results of the subsequent investigation.
Yes the US aircrew where spying on the Chinese, but every military power in the world does it. Indeed the US even does it to it's friends (c.f. Echelon).
I'd lay money on the fact that Dubya, will now definitely sell the Taiwanese all the weapons they want and probably at a discount now.
This is a very old story and not as cut and dried as this meta-post makes out.
IIRC he sold the software, got a job and a share otion from the purchaser, when the project came good, he wanted it his own way and left to start his own company & took the only copy of the source with him. And tried to claim he sold them something else. I think he got what he deserved.
If your really interested I suggest using your fav search engine to dig up the other side.
... but that does NOT mean it has the right to cross political boundries and attempt to tell the rest of the world what it can and cannot have out on it's pages.
The authority of a nation or state derives from it's ability to focus the use of force. In essence your country has authority over you because it can forcibly detain you, not because of any moral authority. It right's are therefore those it can excercise. If it can excercise a [D]DOS, it has the right. It's nieve to believe otherwise.
WOW that's bad!
I thought the UK Solution was bad enough, If it provides unfiltered feeds, it classed as a common carrier and is usually in the clear. If the ISP performs any filterning or access control it's classed as an editor, and accepts responsibility for the content.
A Crypto-analysis attacks the weakest link and weakest in link in a typical Crypto system, including PGP, is the Human.
This type of attack is so common, it even has a name; "rubber-pipe crypto-analysis". Essentially the idea is that cosh is used to beat the key out of the person.
Crude but effective!
So no; whilst we continue to include a Human factor, Encryption is not really secure, because people are not really secure.
All I have to pay is 5.78 UKP for a two year.co.uk registration.
If that's what you're paying, you should check your contract because you'll find that either your don't own the domain, or it's being subsidied by a hidden cost elsewhere in your contract.
You pay that much for domains?
Not personally. However it's what anybody has to pay for a.co.UK domain. It's probably the reason that so many UK companies go for.COM etc.
In theory this seems like a very good system, however it apparently operates as a cartel, with UK netizens paying amoungst the most expensive domains registration fees in the World. Approx 125ukpounds (~200dollars) per annum.
This type of Corporate theft is sadly too common; a former employer (www.marlborough-stirling.com) of mine lifted Gnu Basic & Rtf Parser. They where well aware that it was Licenced & Copyright Software, (I told them) yet they used to sell it for 50,000ukp shot as a print engine toolkit.
It's normal for one fool story to be buried amoungst a host of real stores on April 1st. Slash-Dot seems to have only one real News story buried amoungst a host of April fools.
My only problem is I can't figure out which is the real story:)
Please ask the Germans and British how they feel about the suppression of their political independence under this "United States of Europe" vision.
The Germans are very pro increased european intergration. The British right-wing parties/establishment is very racist and anti-european. However the UK is still largely undecided. The majority of UK people accept the economic agruments in favour, and I think it's only a matter of time.
One thing the EU currently has in droves is an absence of security-related capabilities -- see Bosnia without US involvement.
Europeans are considerable less 'gung-hoe' than Yanks over military action. Do not mistake poltical reluctance for inability. Indeed the UK, Germany and France have first rate military, which in many fields exceeds US capabilities in quality if not quantity. The US had a bit part in Kosova and only political involvement in Bosnia. FYI Kosova and Bosnia are different nations.
I also do not see any European Union controlled nuclear weapons in evidence. Oh wait, the French have them, so that is the continent's nuclear deterrent taken care of.
The UK and French certainly have Strategic Ballistic Nuclear capability, they also have a ocean & theatre capability, IIRC the Germans battle field nukes.
Funny how a deployed and working missile defense system will invalidate it completely. And the Chinese arsenal is also likely to dwarf that of "Europe". Leaving the US and Russia (the dinosaurs) with the nuclear potential to destroy humanity.
The Russians have had functional ABMS system since ~72, and the Yanks have failed to get 'Star Wars' working since 80, indeed it's primarilya sop for the US Military-Industrial complex, who think equipment not training makes for a capable Military.
that one of the oldest civilizations on Earth is not quite a superpower, despite having developed and refined governement and buearacracy for the past 4000 years. Go team!
What is civilised or refined about a nation that runs over it own people in tanks ? or Murders people for political dissent ? or commits genocide on tibetans ? or kills female babies ? or tortures confession from suspected criminals ?
No China; is not civilised or refined by any benchmark, indeed it makes me wonder if your are just a fool or troll ?
Until China makes the breakthrough to a modern democracy it will continue to be a third world nation. History has repeatedly demonstrated that it is freedom and democracy that makes a state 'super'.
I don't think America will be challenged by these entities at all. I think what will happen is that America will *assimilate* these entities.
Challenged in the wrong way to describe these developments. The aims & objects of all modern democracies (Europe, America, Japan, Australia etc) are so convergent and tied into the growing global economy and shared interests that they are never likely to come into serious conflict ever again. Indeed they are so interlocked with Treaties and Alliances that it's effectively impossible. Indeed if any assimilate is to take place it will increasing be of those break-through nation you've mentioned.
I actually think the EU is one of the smaller economic areas, in comparison to the US or to the Asias; do you remeber Japan, Taiwan, China, and Korea?
The GDP of the Euro-Zone (which excludes the UK) is about 109% of the US, if the UK finally joins (likely in the longer term) the GDP will be about 140% of the US GDP. The introduction of the Euro single currency is expected by economists to increase growth and increase this gap.
The bottom line is: what right does the government have dictating who can send e-mail to who, and what the content is? That's exactly what a spam law does.
Wrong!
The law's they break is unauthorised use of the SMTP relay. Essentially it the anti-hacking/cracking laws, that they have broken.
If they used their own or a rented relay, they would have no problems, it;s their own greed that gets the better of them. In my book, they deserve all they get.
I agree, Java has to be a serious contender for your short list, the portability/platform independence will be a serious advantage longer term.
When you consider the convergence between STB's,Consoles and Web-Pad; Java is the only realistice platform for these, and medium term you'll get support for plenty of other client devices, for very-little or even no effort.
The ability to use the same language across the development, on the server side and a range of clients, will make resourcing the various elements of the system easier. All your Coders can work equally well on any of your tiers, Server, middle or Client.
Some will disagree claiming Java is too slow, however this is not really true, ( I use Java to implement an Interactive Digital TV service).
This is especially the case when compared with the realistic alternatives, particularly server side.
The very light-weight nature of Java threads make it highly responsive (low latency) compared to CGI processes. Add a decent JIT and this means it can even out-perform C/CGI.
Java skills are pretty common and increasing, (and look good for your CV:)
