    You are a bit naive.
    Any time law enforcement or a company wants the info, all they need to do is tell Apple to install the "real-time" reporting app over the air.
    Or maybe the "feature" is already a service of the OS just not activated - a single SMS may turn it on.

    Btw, it will not only start tracking from time of activation, it will report all previous history since you bought the phone.

    All this is speculation but that is the point - what is possible because all of the history is stored without your control.

    What if your boss asks you for your logs while you were sick. You can't refuse cause he knows you have the logs. (of course you shouldn't work for a boss like that in the first place...) You can't say I deleted it cause you can't delete it ;)

  4. Re:Java GPL? on Oracle Claims Google 'Directly Copied' Our Java Code · · Score: 1

    J2se is. J2me is not. That's three problem that Google faces.

    Android doesn't implement/use/extend J2ME. Only J2SE classes are included.

    I guess the main claim Oracle has is that Google should have used and licensed J2ME on mobile devices.
    Instead, Google implemented and extended J2SE.

    J2SE was way too heavy for mobile devices before Google came in. That is way many phone manufacturers used J2ME instead.
    J2ME was such a pain to program for compared to J2SE.

    I don't see how Oracle can force a manufacturer where to use J2SE.
    Since phones are just computers with VOIP/phone application, I don't see a problem using J2SE on them.

    While prioritizing may be needed for wireless in general, it should be based on classes of services, like real-time services (VOIP) and non-real-time (SMS, HTTP, u-tube).

  18. Re:Quantum Calculations on First Quantum Byte Created · · Score: 1

    I read an article explaing how you can use it long ago. I'll try to summarize it in a few words with some errors from my memory (it changes state after measurement too)

    ----- factoring (N=P*Q)

    Let's say you have a quantum algorithm ("circuit") which computes p*q=n (n is the result, p,q - inputs)

    If you use conventional computer p and q will be exact values, and you will get exact result n.

    In quantum computing you use qubit vectors for p,q, and n.
    A single computation actually computes all possible values for p,q, and n such that p*q=n.
    (That is because qubits are superpositions of 0 and 1 instead of exact values.)
    This is called quantum parallelism.

    Whenever you make a measurement, you will get a single solution (from all possible) with exact values for p, q, and n such that p*q=n.

    Now, if N is some 2000 bit number used in a public key you want to break, you can use some tricks such that you measure n to be actually N you are interested in with some probability.
    The probablity of success is far greater then 2^-2000.

    So you make a 1000 or 1000000 measurements (compared to 2^2000) and you will get n=N, but p and q from the same measurement will be the soultion to the factoring of N=P*Q.

    ----

    How do you explain quantum parallelism.

    Let's think of a qubit A as a vector A in 2-D space.
    If you project A on some basis vector B you get Ab = k*B, where k is a scalar, Ab the projection of A onto B.
    If k is positive then the measurement of A is 1,
    if k is negative then the measurement of A is 0,

    Now, for the same A, there always exists basis vectors B0 and B1 such that the measurement of A onto them produces 0 and 1.

    Example:
    A is (2,-3), then
    if B1 is (1,0) then Ab1 = 2*B1 => A will be measured as 1
    if B0 is (0,1) then Ab0 = -3*B0 => A will be measured as 0

    If you have a "qubyte" or 8 qubits, there always exists different basis vectors that produce all possible measurements from 0 to 255.

    So, depending on your measurement, depends which result you will get, but all results are "there".
    There are tricks to measure a result closer to what you want it to be (n=N).

    One clarification why they are doing this:

    They want to make passport verification fool-proof.
    Something like this:

    When you walk up to customs,
    camera takes a picture of you,
    software calculates biometric measures and
    compares them to the one stored in your passport.

    Biometric measure is not comparing the 2 photos. It may also compare placement ratio of eyes, nouse, chin, etc. or even a fingerprint.

    They hope this will be more accurate then a tired human looking at a picture and you and comparing them. Or maybe even pre-scanning before reaching customs...?

    However, bioemetrics is not that accurate yet.

    Electrons, positrons, protons, and neutrons are particles with mass and they are not light.

    When electrons or positrons move (current) they produce electro magnectic waves which are light.

    What they develop is the ability of devices like CPU and memory to comunicate using light and thus giving them more bandwidth.
