    HA ! I should move to Holland ! In Germany you have to pay the TV/Radio tax if you have a receiving device (even if you have for example a Radio+CD player and you only use CDs because you don't know german). You have to pay the TV/Radio tax if you have a PC, only because you could use your pc to listen to radio/tv on-line !!!!

  3. Re:Encryption? on Prime Numbers Not So Random? · · Score: 1

    The short answer is no, it won't be "pretty fast". There are just too many prime numbers between 2 and sqrt(A), if A is something like 2^1024 or 2^2048 or 2^4096 (...) to test them all.
    Right now we have better (=faster) ways to factor large integers than to bruteforce for all the prime numbers smaller than sqrt(A). Way faster.

    Think about it. There are about x/log x prime numbers smaller than x ! There are too many prime numbers to generate between 1 and 2^200, even if you generate one prime number in a clock cycle, no matter how fast is your computer or how many computers you have !

  4. Re:I found a pattern! on Prime Numbers Not So Random? · · Score: 5, Insightful

    Of course they are prime ! ANY number is either:

    6n (not prime of course)
    6n+1
    6n+2 (not prime of course)
    6n+3 (not prime of course)
    6n+4 (not prime of course)
    6n+5

    And 6n+5 is the same as 6(n+1)-1 so indeed you are right. You deserve a price for finding a 6th grade theorem.

  5. Re:Encryption? on Prime Numbers Not So Random? · · Score: 1

    RSA is "strong" not because we cannot generate prime numbers (or test if one given number is prime). In fact we can do both things VERY fast.

    RSA is "strong" because we cannot solve fast simple ecuations like x*y=A (where A is BIG, x,y integers). And bruteforce is NOT the fastest method available to factor integers. If it were, yes, it would help to have a faster algorithm to generate/test primes. But it's not.

    Uh, I fail to see why this was moderated as interesting. "128 bit technology" ? I assume you are talking about symmetrical alg., like IDEA, CAST, and many others. These are not even remotely related to prime numbers (some of them are, but not very close). And it's already simple enough to generate big prime numbers.
    Next step is to ask: "will my Diesel car become obsolete because of this theory" ?

    The Pythagorean Theorem is a Theorem because it fits the definition for the Theorem, not because some stupid reason about infinity. A theorem is a logical assertion which can be proved using (=it is implied) by the axioms (statements which are given to be true).

  10. Arc Flashlights on Which LED Flashlight Do You Use? · · Score: 1

    I wonder why nobody mentioned arc flashlights

    www.arcflashlight.com

    The ARC AAA uses one AAA (surprize) and it will be BRIGHT for many hours (it's semiregulated). You can read or hike or do anything at night with one VERY small light (smaller than Mag$ Solitare). Just visit the web site and you'll see what I mean. The small light is of course waterproof; and the head is totally sealed; you can take the light apart under water without any problems. This small light has been freezed inside an ice cube, boiled in oil and run over by SUVs. Did I mentioned it's HA (hard anodized) III. If you wonder why HA III is important just look at your Mag$ Solitare (regular HA) and you'll see what I mean.
    By the way, Mag$'s does not qualify (IMHO) as "high quality existing flashlight". Maybe they were, 30 years ago. Maybe they still are compared to 1.99$ lights from department store. But for example a Princeton Tec 40 (around 12-25 $) will be smaller (fits in a pocket) and about 60 g (!). With batteries (standard 4xAA) will be around 130g. And will have a nice white output (no rings). In a 3D Mag$ you'll find: ringy, yelowish output (and less brightness), about 460 g dead weight + 400-450 g for batteries. Oh, and the Princeton Tec is waterproof to 2000 ft (yes 2 and three 0) while mag will be flooded if you try to see how it's working in the pool.

    I am too soo sick about this "flash in everithing" thread.

    At some point we had to return/replace more than 50 creative sb awe 64 because the firmware got "corrupted" sometimes. 3 years later we found a software to rewrite the flash on these cards. Why do you need to put R/W memory in a device and leave it R/W so any random event (read windows "detect hardware" thing) will kill your device ?

  22. Re:What will happen after the Megapixel race? on 13.8MP Kodak Tops Previously Leaked Canon · · Score: 1

    I am quite surprised that nobody pointed out that we are victims of marketing. ANY digital camera will advertise the number of RAW pixels, that is you get this number if you shout B/W. If you want colour, there is a process called demosaicing, and you end up with about 1/3 pixels (it's a little bit more complicated, depending on bit-depth and the actual algorithm, but 1/3 is close). Example: an old film scanner (minolta dimage dual scan II) will get from a 35 mm frame a little bit over 10 000 000 pixels (no interpolation, no tricks). This are "real", "color" pixels. To match this with a digital camera you need 30 Mpixels (= advertised Mpixels).

    Or maybe the space contraction made the distance smaller ? There are MANY pitfalls in relativity. However, the page looks all right (they state that it's not possible to send information faster than light).

    to quote:

    Information coded using a light pulse cannot be transmitted faster than c using this effect. Hence, it is still true to say that "Information carried by a light pulse cannot be transmitted faster than c." The detailed reasons are very complex and are still under debate. However, using this effect, one might be able to increase information transfer speed up to c. In present day technology, information is transmitted at speed far slower than c in most cases such as through the Internet and inside a computer.
