  1. Re:If you look at these clones on Apple Possibly Pursuing Another iMac-look Clone · · Score: 2

    Read the article. Apple didn't beat Future Power and eMachines in court. They settled out of court.

    They were bullied by a bigger company and they folded rather then take it to court.

  2. Apple = Amazon on Apple Possibly Pursuing Another iMac-look Clone · · Score: 2

    This is just as silly as Amazon copyrighting "one-click". Maybe I've been in a cave my entire life, but I seem to remember there being translucent colors before there was Apple and the iMac.

    Jobs, why stop with computers? There are plenty of other companies you can sue. Makers of pagers, cell phones, console gaming systems, etc. are all riding the "iMac" wave.

    Think different, my ass. Think VICIOUS. Maybe this would be a good time for Microsoft to sue Apple for emulating their business practices.

    You're right. I'm wrong.

    It is spread spectrum. The spectrum is just very narrow.

    Even more than just a serious nuisance. I'm not sure if they are actually using it yet, but years ago, the F.A.A. was investigating GPS for use with instrument landing systems on commercial aircraft. As posted elsewhere in this thread by hpa, the F.A.A. issues NOTAMs whenever the military is testing GPS jammers. A hazard to navigation is much more than just a nuisance.

  6. Re:Why? Here's a coupla reasons... on Engineers Build Satellite Jammer · · Score: 1

    Now, I am not a EE, much less a DSP/GPS specialist, but from my knowledge of the system I am guessing that: a) the system described above won't be much use against fast-moving airborne GPS (fighters)...

    Generally, it's assumed that radio waves travel at the speed of light. The speed of a fast moving aircraft isn't relevant.

    Look at it this way.
    1. The satellites are very high.
    2. The antenna is placed on top of the vehicle.
    3. If your jammer is on the ground, the jamming signal can't pass through an aircraft to get to the receiving antenna.

    If you don't belive that, put your GPS receiver underneath your car and see how well it works.

    You can't jam the transmitting space vehicle. You can only jam the receiver on earth.

    It's not spread spectrum.

    The L1 frequency (1575.42 MHz) carries the navigation message and the SPS code signals. The L2 frequency (1227.60 MHz) is used to measure the ionospheric delay by PPS equipped receivers.

    Three binary codes shift the L1 and/or L2 carrier phase.

    The C/A Code (Coarse Acquisition) modulates the L1 carrier phase. The C/A code is a repeating 1 MHz Pseudo Random Noise (PRN) Code. This noise-like code modulates the L1 carrier signal, "spreading" the spectrum over a 1 MHz bandwidth. The C/A code repeats every 1023 bits (one millisecond). There is a different C/A code PRN for each SV. GPS satellites are often identified by their PRN number, the unique identifier for each pseudo-random-noise code. The C/A code that modulates the L1 carrier is the basis for the civil SPS.

    The P-Code (Precise) modulates both the L1 and L2 carrier phases. The P-Code is a very long (seven days) 10 MHz PRN code. In the Anti-Spoofing (AS) mode of operation, the P-Code is encrypted into the Y-Code. The encrypted Y-Code requires a classified AS Module for each receiver channel and is for use only by authorized users with cryptographic keys. The P (Y)-Code is the basis for the PPS.

    The Navigation Message also modulates the L1-C/A code signal. The Navigation Message is a 50 Hz signal consisting of data bits that describe the GPS satellite orbits, clock corrections, and other system parameters.

    I can't speak for the herd. I'm cruising at a level sufficient to read your posts.

    The moderation system may be flawed, but it's an interesting approach to filtering in a bulletin board. I can't say I agree that the system is actively censorsing. It restrictions are arbitrary or at least seem so in my perspective. If you want to read everything, you can.

    Look at the bright side. There's no system in place that filters posts from people with low kharma.

    The library of Congress contains many areas of information that could be particularly hurtful like the propaganda collections from several wars, a treasure trove for racists. Most of the readers of /. would throw a fit if a web page with this material opened, now your demanding the LOC put it online.

    Are you saying that most /. readers are for censorship? I can't agree with that assumption. I'm certainly not in favor of censorship, no matter how distasteful the material.

    I personally don't like to think that our treasures should be placed on such a degradeable medium that might be lost in the event of a technological hiccup.

    This argument is flawed. The digital data doesn't have to replace the paper that's already there. In any case, having a book in a form that's easily copied should make it much simpler to be preserved. Paper rots. Digital data flows and multiplies. Ask the MPAA and RIAA. They are currently terrified by this fact.

  17. Adverse Fiscal Effect on Censorship: It's Not Just For Web Sites · · Score: 3

    This could ultimately turn out to be a bad thing for the police forces.

    As an example... Although the Department of Justice has reported a decline in the amount of teen violence and murders, the news media has the general public convinced that it's actually the opposite. Net effect, people vote for politicians and laws that throw increased funding at the problem, mainly in the form of law enforcement.

    Maybe the police need to rethink that. The minute people feel safe, funding is diverted elsewhere. Having the media around to sensationalize ultimately profits the police business.
