Eventhough it looks as if it has been written for a layman , the article is quite cryptic (and IMHO nothing new).
If someone tries to intercept this stream of photons--call her Eve--she cannot measure both modes, thanks to Heisenberg. If she makes the measurements in the wrong mode, even if she resends the bits to Bob in the same way she measured them, she will inevitably introduce errors. Alice and Bob can detect the presence of the eavesdropper by comparing selected bits and checking for errors.
Ok, if you use a single photon to send the information , it cannot be eavesdropped. But in the current networks it'll only go around a couple of meteres at Max and you can't use an amplifier/repeater with this. So really, how are we going to use this in real life ?. The concept has been there for decades now - ie an OTP created with entropy drawn from the quantum uncertainity rather than just psuedo random codes.
The real advantage of using entangled photons would be in sending information faster than light. Entangled Photons in Computers actually might solve all the copper issues in speed we're having in chip DIE size vs clock speed (as in how to get a signal from one end of the chip to the other in a single clock signal).
Lawyer: Is your copy of the file an identical copy of the original DVD ?
H4x0r: Hell No !.. the DvD was like 4 GB while my Divx is around 800 Mb..
Lawyer: So they are not identical ?
H4x0r: No, I also put my Logo on the top to advertize my website
Ever seen Death Became Her ?. Or did you ever read about Wowbagger or see the Green Mile . You might think it is a joke on immortality, but I think that these are far more realistic than we imagine.
Of course, I'd like to be young for 100 years rather than be a vegetable in bed for 300.. The real trick of immortality is staying young, not living long.
Living longer than the norm NOW is a good thing , especially when you think about space travel and all that.
When Guns are outlawed, only outlaws will have guns...
Soon you'll see that only links with tag rel="nofollow" will count as geniune links because the spammers do NOT use that as much as the regular users..
Just like spammers were the first people to implement DomainKeys:)
I've heard this a LOT about copyright being there to promote innovation , but most people forget the "for the betterment of society" part of it. altruists.org has the right ideas, but nobody with any real clout has said it so far. Until Now !!
Reworking Copyright pretty much covers how I feel about copyright.. (though not written by me).
For example , Gandhi was a great proponent of "Making money is not evil" (being from a business community) unlike the England educated Nehru's socialism. People rarely distinguish between the cost of an object and it's price:).. As long as the price is not paid by society (rather than an induvidual) , copyright holds. Interestingly society profits when an induvidual pays or that's the way copyright was supposed to work.
otherwise things like dynamically-loaded libraries wouldn't work too well.
I'm talking about userland tools which do something like -
JITcompile(bytecode); bytecode->__func(args);
They preferably mmap space off/dev/zero and unlike a shared lib loader can't operate in kernel space (we're talking about NX in userland, not ELF loaders).
However, when I see comments like FSF's "The enemy is proprietary software", I'm not greatly impressed in a moral sense. The enemy is not software written for a direct profit, and business is not all about philanthropic ventures.
Dude, RMS used to sell copies of Emacs for $150 per tape !!. (Windows XP costs $63 for an OEM, and that was in 1984-86)..
Proprietary != Commercial [how do I hammer this into the heads of the other "Open Source" guys here].
And if the NX bit were used for more than the stack, then it could protect against a lot of (non-trojan) viral activity too.
So would all the JITs that everyone's built so far.. Remember that not all code blocks are loaded as readonly off the disk. I had to go through a couple of hoops to get portable.net to work on OpenBSD..
In short they would have to provide a way to mark a write-able buffer as executable - and I suppose you'd call it the next design mistake ?.
Read about PAE and JITs (hint: dotnet ships with AOT capabilities)..
Diving stuff and boats were the major disaster area.. I think Sri Lanka is a bit more exposed than Kerala was.
The wave in kerala went nearly 4 kms inland (though it's through the backwaters) and I'm still having painful memories of seeing a white mercedes floating around in the basement of a building...
The Marine Drive is around 6-7 feet above sea level and is the major business/market area in Cochin - thankfully we're on the right side of India to be compared to the earthquake.
Thanks to a timely news on radio and TV , only a few hundreds were caught unawares... East coast was not so lucky.
1.3.8 Computer Programs 1. Computer program is not patentable invention as computer program is a set of instructions for controlling a sequence of operations of a dataprocessing system. It closely resembles a mathematical method.It may be expressed in various forms eg. A series of verbal statements, a flow chart, an algorithm, or other coded form and may be presented in a format suitable for direct entry into a particular computer, or may require transcription into a different format (or computer “language”). It may merely be written on paper or recorded on some machine-readable medium such as magnetic tape or disc or optically scanned record, or it may be permanently recorded in a control store forming part of a computer. Thus it is evident that a program may be presented in terms of either software or firmware.
With such a clear law stating about firmware, how can patents be applicable to embedded systems ?. The normal programmer need not fear yet. But this is just the first wave.
An invention consists of hardware along with software or computer program in order to perform the function of the hardware,such invention may be considered Patentable
Maybe this is the clause they are exploiting ?.

Just because it happened to the cream of America's corporate structure doesn't make 9/11 horrifying... It's not the body count... It was not a tragedy - it was an act of malicious intent by a group of people - who had to kill thousands of people to be taken seriously !!. That's what's HORRIFYING about it.
The relative significance of human tragedies are indeed ranked by the percentage of human population wiped out. A life is a life , no matter who they are (primitive savages or corporate executives). If you want to compare the Tungska meteorite with the flash tide flood in Chennai - I'd think the latter deserves more of our concern...
As a species , we should grieve the loss of valuable genetic diversity - It's something that comes naturally to any creature of sufficent intelligence (look at some elephants in Periyar , they literally cry over year old bones).
Software is not "Free" as in beer - when people do publish software Freely , they are doing charity. FOSS software can be sold (RMS sold emacs for 150 USD per copy !!!). But what FOSS tries to seperate is the Cost of Development from Profit per Sale.
I have been (wioll haven been) paid to do some features on the OSS I work on - because somebody really needed it. That's because I created some wealth with my effort (in a wholly capitalistic point of view). And Everyone else gets the stuff for free and in short - Everybody wins.
Piranha to Scurfy by Ruth Rendell has a lead character who is a lonely man who vents pleasure from nitpicking on other people's literature... I didn't actually notice it wasn't "Scurry" and didn't until I read quite a bit into the book:).
Very similar character ?.
The inaccuracies are obvious when you read some books (especially books written with decades between them , read in a week or so). For example, I did pickup on the color differences of the lasers in the Dune series written by the son of Brian Herbert... (ie purple to orange) or the Bastardization of Holtzmann as a person (read Dune encyclopedia).
It's an infra red telescope and all that... it can see a lot of stuff in space BUT the photo I really loved was this Down to Earth Night shot of the telescope itself....
A Games CD for Linux on BitTorrent ... mmm..
on
Games Knoppix

What games on that CD ?. Is it just the ordinary TuxRacer... Or have they included the demos for Quake3 and stuff like that ?. (It's already slashdotted).
Thank god the the download won't get slashdotted - BitTorrent tracker looks great (quite enough seeds).
RMS is unreasonable - which means he cannot be REASONED with - which is not essentially bad.
To quote Bernard Shaw:
The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.
People hate change, RMS wants change , and therefore.....
Vulnerabilities are not hard to write - they are hard to detect and often easy to fix.
Most FOSS programs are the result of someone who really wants to write something good. Rarely have I seen someone being forced to write FOSS code to meet a release date schedule or to remain competitive. It's about It'll be done when it's done, sort of Code Poetry. Most of the code was written to run in a hostile environment where black hats can read the code (like the above peice) and screw everyone who runs bad code. The term security in obscurity as far as coding style does not even enter your mind.
Also vulnerabilities are easier to find when you have the source - like that professor who set his students to find vulnerabilities in FOSS. Unlike a corporate setup - you have a practically unlimited number of reviewers if your program is popular (and if it is not, a vulnerability is no big deal anyway, right). Also everyone runs a different binary, slightly different from what everyone else runs (security often needs you to recompile stuff with stack canaries)
So FOSS software evolves (yes, Natural Selection) to avoid these vulnerabilities by dying out or it "adapts" - Someone adds more good ideas and makes it better like.. (s/ideas/genes == Sexual reproduction) . Also the good ones read Wietse's papers.
I work on a VM myself, would it be possible to port it to Symbian easily (has 500k footprint on ARM) ?.
And where's the Source dude !!.. I want Nokia to OpenSource it. Where I work, there are guys with p800i smartphone , if they had released sources, I could have taken a shot at building it for Ericsson (maybe that's why they haven't).
