  2. Standard theories for sleep disorders are WRONG ! on Be Thankful If They Just Snore · · Score: 0
    Every 2 or 3 years some "scientists" claim that they found the reason for sleep disorders and annouce a perfect cure. But this usually crap because there is no cure for sleep disorders due to sleep disorder being not an illness.
    Sleep disorders are a simple physical phenomena which is caused by a wrond placed sleeping location. Sorry, I won't call a wrong placed bed an illness.
    Most slashdotters come from an academic background and therefore know some simple fact about the human brain. Information processing in the human brain is done by electrical signals. These are rather weak signals with an energy about 0.27 mW. The part of the human brain which is responsible for movements and basic body states like "awake", "asleep", "aroused" is the cerebellum.
    An important part of the cerebellum is it's main cortex which is coincidentally build like coil (from an electr-chemical point of view). This enables it to react very fast to changes of the surrounding but unfortuantely makes it work like an antenna, too. The neural structures of the brain are of course able to filter of most induced noise from the cerebral cortex, but some special signal get trough. That means especially:
    1. Vertical slow frequency (0.0045 Hz) noice induce e.g. from the moon passing through earths magnetic field (moon has a metallic core like earth)
    2. 50 Hz left-right oscillations (for example if you have a power plug left to your ear when you are sleeping)
    3. 120 Hz radial oscillations (for example from a computer screen, therefore you should never sleep in front of your computer)
    4. 9485 Hz oscialltions at head height (therefore many people have problems relaxing at the dentist)
    Note that most interferences are basically directional so just moving your bed might help alot. For the interferences caused by the moon the best thing would be prtective shielding like a nightcap made of wires (Faradays cage for the brain).
  3. There is a much more dangerous threat. on Environmental Impact of the Ubiquitous Microchip · · Score: 0
    With more and more embedded systems are used in devices are over the world, more and more embedded chips find finally their way onto the garbage dump. But the big problem with these chips that they can't be neither termally recycled, i.e. burned -silicone is a metal after all - nor remelted for new chip - silicone dioxide is just sand therefore it would be too expensive. So these chips accumulate in huge heaps on the garbage dumps.
    However, these chip are never really destroyed the basic logic is still in them. Now the natural radiation which is much higher on garbage dumps than you would expect comes into play. It's struture altering effect creates basically a natural genetic algorithm on these chips which breads something which could be best described as silicone lifeform - it's slightly reproducing and adaptable.
    Currect simulations show that in about 20 years these heaps will have reached nano-fracmentation. This means that they will send of little silicone nano-lifeforms comparable to bacteria. These thing are not a direct threat to the normal lifeforms on this planet - all life is carbon/hydrogen/nitrogen-based and not silicone-based. However simulations show that these silicone bacteria will spread all over the hull of earth (70 % silicone) and will eventually "mutate" to incoporate iron. This means that 85% of the outher hull of earth will be destabilized. Earth rotation and gravitation from moon will do the rest - our planet will slowly evaporate into silicone bacteria dust.

    It's very important to do something about these problems, that mean either - shipping old computers to Mars for savety (radiation is lower there because Mars is older than earth), melting down all old embedded devices or sterilize them with underground nuclear explosions.
    However G.W.Bush is more occupied to save America oil supply in the gulf region than to do something against evaporation of earth.

  4. Wrong point of view. on Large File Problems in Modern Unices · · Score: 0, Interesting
    There is not a problem with support of large files in Unix system, there is a problem with incompetent people using too large files in Unix systems.
    It's an old and well known problem that programmers and users tend to keep very large files for laziness and logical errors.
    However it's also an old and well known fact that large files are bad for performance per se due to several reasons:
    • fragmentation: large files increase to fracmentation of most file systems, at least of any system with uses single indexed trees/B-trees and nonlinear hashes
    • entropy pollution: large files increase to overall entropy on the harddisk leading to worse compression ratios for backup and maintenance
    • data pollution: the use of large files tempts users to store all kinds of redundant, reducible, linear and irrelevant data wasting storage space and I/O time
    So I don't see why admins should provide a "work-around" for the filesize limits. These limits are there for very good reasons and in my opinion they are even much to big. You should always remember that the original K&R Unix had only 12 bits for file size storage and was much faster than modern systems, in fact it did run on 2,2 MHz processors and 32 kB of RAM which wouldn't be sufficient for even a Linux of Windows XP bootloader.

Furthermore the above mentioned experiment doesn't provide any new information.

  6. This is hardly news. on TWIRL: Are 1024-bit RSA Keys Unsafe? · · Score: -1, Troll
    The whole security of the RSA algorithms depends on the assumtion that the discrete logarithm problem over finite fields is hard to solve.
    But want most people ignore is the fact that this only makes sense for sufficiently large instances of the problem. It's a well known fact that up to a given limit instances of all PSPACE-complete problems can be solved extremely fast. The trick is to go to the analog domain and solve a suitable approximation. Up to a given limit this approximation is good enough to get a solution just by rounding. This limit mainly depends on the Heisenberg and the cosmic constant due to the uncertainity principle. Note that without the uncertainity principle all computational problems could be solved in O(n^2 log(log(n))).
    In the case of the discrete logarithm we have to embed the field Z/2Z in the Lie group SU(2). The logarithm problem is to find a QO-representation of SU(2)x...xSU(2)=SU(2)^n where n is the key length and map it back onto Z/2Zx...xZ/2Z. This can be done in finite time by a n-series of coupled hamiltonian systems. This can be implemented by a series of n coupled 2-harmonics oszillators (just enough resistors, independancies, capacities and some triacs). The uncertainity principle comes into play to fuck up the results if n>1414. That means that we can break RSA-1024 keys in finite time.

    If computer scientists would pay more attention to mathematics, then such thing wouldn't happen at all.

It's one of the reasons why you should watch TV only from a larger distance 2 meters or so (the other is of course gamma radiation). However this implies that you really can't see the very little details. But the point about DivX compression is in fact these details. All older compression schemes used to delete these due to lossy compression.

    The only problem is that most of responsible people are computer scientists and sometimes even only with a BS in CS and therefore have no clue of harmonic analysis and advanced probability theory.
    If you project your network system in the C^n- space of markovian probability measures and with to the frequency domain, you can easily see that our system represents a compact manifold of superharmonic measures. And malign overflow is just a upper bound in this set, therefore harmonic. It's well known that the only harmonic functions on compact manifolds are constant. So going back into the time domain this means that you must just analyze the frequency of the packets. All packet streams with a constant frequency are malicious by the above calculation and therefore should be dropped. Of course there are some minor points with the frequency reflection on edges etc. but this is very basic stuff and can be easily solved.

    It's a well known problem in EE design that this disbalancing might result in unstable, chaotic behavior. This is particulary problematic because the basic design of most electric circuit contains a large Kalman-Barsharotiwz feedback filter. Together with the missing stability this creates an undamped increasing oszillation which will basically blow up your entire set up. EE PhD's will surely known this as the Lillehammer effect.

  12. Come on, you cannot land on mars. on NASA Wants Astronauts on Mars by 2010 · · Score: -1, Troll
    If you take a close look at Marses ecliptic parameters, its size and speed, you'll come after some basic calculus to the result that either the average density of Mars is 0.2 or its rotation speed is about 20 angle minutes per second. The latter can be proven wrong by observation.
    This lead to the fact that is body "Mars" is in fact a could of red gases with some solid rocks floating on the surface. This explains why Mars has no atmosphere - it is an atmosphere by itself.
    You will know argue with the pictures from Viking/Mars Lander etc. But NASA usually uses "clean" wide open spots for landing. These (very few) sites on Mars are the above mentioned rock parts floating on the gas. The "mountains" you see in the background of these pictures are in fact "hills" of frozen gas (temperatures on Mars are very low). This strange structure explain also the "canals" on Mars watched in the 19th century. If you check Mars ecliptic you'll see an opposition with Saturn and Jupiter at this time. This lead Mars to be drawn nearer to the sun, heating it up and letting the frozen gas on the surface crack. That's why we don't see canals today. The "valleys" of Mars come from the different freezing temperatures of different gases carbonmonoxide has a higher freezing temp. than diheliumtrinitroamide (DHTNA, very common in space) and so craves out valleys like water in the frozen gas.

    So I don't think you can land on Mars. A real grown spaceship is no small probe. Scientists exstimate the carrying capacity of the floating rock parts to be very low, they were surprised that not more probes just vanished (some did as you'll surely remember). Most people I know won't bet a dime that it's enough for a full grown spaceship. I think Bush must think of something else to demonstrate his national pride.
    Venus, Merkur are not options due to the atmosphere resp. the heat and the moons of Saturn/Jupiter are already the goal of the Europeans. So you have to wander real far like Uranus of Pluto.

    Despite all critics from well scientific authorties the members of the Blinkenlights Project have refused to increase the default blink frequency to 25 Hz. Only at this frequency damages can be really ruled out. The only reaction they got was: "Plz shut up, wnkr. Thx."
    However, at this point I must warn you the set they blinking frequency at the blinking applications too high. At frequencies above 143 Hz the Starnikov-Holderman effect comes into play which has effects on the visual cortex, too.

    As a mathematician I'm usually very spectical of everything physicists publish.

    However, in the case of quark matter I'm more then just spectical. There is almost no experimental proofs for quantum field theory. And there is no reasonable argument for the choice of 11 dimensions (1 time, 10 space, 6 compactified). Any beginning graduate mathematician can easily proof that the whole theory works out in any 11k+23m dimensions, k a natural number, m a positive integer. There topology of such spaces is less known of course, but that's no reason to reject it a priori. And it's a well known fact in the mathematical community that in the 11*3+23*3 case supersymmetry can by explained much easier due to the fact that several cohomology groups of the Yang-Chibara manifolds are simple and the remaining ones freely generated.
    Due to the very weak theory I would reject such explanations beforehand without even brothing to check the data. It's just a waste of time.
