Quantum cryptography:
2006-05-11 13:50:00
Is an approach based on quantum physics for secure communications.A central problem in cryptography is the key distribution problem.One solution, that of public-key cryptography, relies on the computationaldifficulty of certain hard mathematical problems (such as integer factorisation),whereas quantum cryptography relies on the laws of quantum mechanics.Quantum cryptographic devices typically employ individual photons of light.How...... ?it is possible to encode information into some quantum properties of a photonin such a way that any effort to monitor them necessarily disturbs them insome detectable way. The effect arises because in quantum theory, certainpairs of physical properties are complementary in the sense that measuringone property necessarily disturbs the other.SO..... ?Two different types of quantum cryptographic protocols were invented:The first type uses the polarization of photons to encode the bits of informationand relies on quantum randomness to keep you from lear...

Malicious cryptography: armored virus
2006-05-11 13:43:00
When the malware is detected, it is regarded as new code to be analyzed.When the analysis is completed, signatures and heuristics are created toenable anti-virus software to block this malwareIn order to avoid this "problem," a malware writer must delay, or evenforbid, the analysis of his malignant creature what's called _armored virus_.It has several techniques:Polymorphism: both the binary and the process were cipheredStealth: several interruptions, including debugging ones, are hookedby Whale, and it also hides in high memory before decreasing the maxlimit of memory known by DOS, which was prominent at the time.Armoring: the code changes depended on the architecture (8088 or 8086),and had what is known as anti-debug(if a debugger is detected, the keyboard is blocked and Whale kills itself).

Why Micro$oft Causes Stupidity
2006-05-11 02:24:00
Too many people just get stuck on "Yes, but they're making money",Others: and stay with"They're popular", or even the dreaded"They made it possible for anybody to use a computer",or other catchphrases which tend to just derail real arguments.And it's not because they're valid points,it's because they're practically impossible to address;they're perfectly valid points, but in a totally different context thanthe one the arguments are in.If you don't know/Understand something, you're stupid about that something.I'm pretty stupid about Civil engineering.If you don't understand computers, you're stupid about computers.You're not bloody well "computer illiterate". It's a failure phrase,and the only reason to use a copout phrase is to attempt tobe dishonest against other people and/or yourself.Admit it; you're stupid about computers. It's not a stigma,it's an admission.Ex: User friendly means "easy to use".We can all agree on that, I think.And it's what we mean when we sa...

What's So Bad About Microsoft?
2006-05-11 02:14:00
Why is it that Microsoft 's products keep increasing in sizewith each new release always requiring significantly more disk spaceand more processing power than the last time?This is Microsoft's way of rubbing Intel's back so thatIntel will give Microsoft preferential treatment when it comes outwith new chip specs.It's also Microsoft's way of convincing consumers that their newer productversions are better because they are so much bigger.At the time that an Open source Soft wares + OS not more than 4 GB.Any comment ... ?

The Luhn algorithm
2006-05-08 02:05:00
A method of validating identification numbers. It is a simplechecksum formula used to validate account numbers,such as credit card numbers and Canadian SocialInsurance Numbers.it protects against accidental error, not malicious attack.Starting with the second to last digit and moving left,double the value of all the alternating digits.For any digits that thus become 10 or more,add their digits together.For example,1111 becomes 2121, while 8763 becomes 7733(from 2x8=16 -> 1+6=7 and 2x6=12 -> 1+2=3).Add all these digits together.For example, 1111 becomes 2121,then 2+1+2+1 is 6; while 8763 becomes 7733, then 7+7+3+3 is 20.If the total ends in 0 (put another way, if the total modulus 10 is congruent to 0),then the number is valid according to the Luhn formula,else it is not valid.So, 1111 is not valid (as shown above, it comes out to 6),while 8763 is valid (as shown above, it comes out to 20).

Numbers proof
2006-05-07 23:03:00
2= 2.30100 - 100 = 200 - 200 {By taking the log of the 2 hands}Log 100 - Log 100 = Log 200 - Log 2002 - 2 = 2.30 - 2.302 (1 - 1) = 2.30 (1 - 1)Then 2 = 2.30Lame isnt it ?

Case-Based Reasoning
2006-05-07 09:46:00
Case-Base d Reason ing relation to Genetic algorithm and Data mining.Case-based reasoning has been formalized for purposesof computer reasoning as a four-step process:Retrieve: Given a target problem, retrieve cases from memorythat are relevant to solving it. A case consists of a problem,its solution, and, typically, annotations abouthow the solution was derived.Reuse: Map the solution from the previous case to the target problem.This may involve adapting the solution as needed to fit the new situation.Revise: Having mapped the previous solution to the target situation,test the new solution in the real world (or a simulation)and, if necessary, revise.Retain: After the solution has been successfully adapted tothe target problem, store the resulting experience as anew case in memory.G.A / is a seaerch technique to find approximate solutionsto optimization and search problems .Data Mining: can be defined as "The nontrivial extraction of implicit,unknown, and potentially useful informatio...

Mother
2006-05-07 09:27:00
The desolation and terror of, for the first time, realizing thatthe mother can lose you, or you her, and your own abysmalloneliness and helplessness without her.The tie which links mother and child is of such pureand immaculate strength as to be never violated.I miss thee, my Mother ! Thy image is stillThe deepestimpressed on my heart.A father may turn his back on his child, brothers and sistersmay become inveterate enemies, husbands maydesert their wives, wives their husbands.But a mother's love endures through all.The mother is queen of that realm and swaysa scepter more potent than that of kings or priests.Mothers are fonder than fathers of their childrenbecause they are more certain they are their own.A mother always has to think twice, once for herselfand once for her child.Mothers most of all,who carry the key of our souls in their bosoms.

GHz radiation
2006-05-07 04:36:00
Effects of GHz radiation on the human nervous system: Recent developments in the technology of political controlThe United States has developed communications equipment which can make the blind see, the deaf hear and the lame walk. It can relieve the terminally ill of all pain, without the use of any drugs. A man might retain the use of all his faculties up until the day of his death.This communications equipment depends on a new way of looking at the human brain and neuromuscular system, and gigahertz radiation pulsed at ultra-low frequencies.Some of this equipment is now operational within the Central Intelligence Agency and the Federal Bureau of Investigation. It will never be used to make the blind see and the deaf hear and the lame walk because its use is central to the domestic political agenda and foreign policy of James A. Baker and George Herbert Walker Bush.Domestically, the new communications equipment is being used to torture and murder persons who match profiles imagine...
