  1. Re:You'd need much larger conductors on Are Data Centers Finally Ready For DC Power? · · Score: 4, Informative

    No the skin effect is for (High frequency) AC.

    For DC impedance is determined by the material and the cross section area.

    It does make the cables easier to bend though.

    Lower voltages require larger conductors to carry the same power, (due to I^2*R losses). Copper isn't that cheap.

    FTFY

    Losses in a wire are determined by the current alone.

    learned it whilst developing military communications systems.

    There are so many ways that could be less impressive than it sounds if you don't deny my first line. Yes i did judge you on the existence and contents of your Journal.

    Paul Shannon showed increasing power does bugger all for you in the end.

    He showed its horribly inefficient but there a 1.5 m range these don't suffer too much from inverse square. He also showed that if you don't have more power than the interference you are fucked.

    You sound like you learned that in Masters or Summer research but have never used them, apologies if not.

    Not that my education is any higher but at that range and considering other power requirements increasing transmission power would be the easiest way as transmission failure could be almost as bad as mis - communication. At that range you can ramp up the power for whatever band-with you need i guess though.

    For some implants you would also want to favor the MSB as errors on the smaller ones may be ok.

    Chances are most likely form of interference would be other people implants (at say a support group) so you would want maximize the number of channels as no amount of ECC can account for two people next to each other on the same channel.

  7. Re:Interferance would suck on Bionic Implants and Spectrum Clash · · Score: 1

    Not that it would effect the GP solution (which is overkill at that range) but encryption would the problem more difficult and certainly does not solve it. You now need to communicate uniformly distributed data perfectly which is much more difficult.

    To stop other people intentionally interfering with your device is where encryption/cryptography would be useful.

  8. Re:Microsoft Zealot Here... on OpenSUSE 12.1 Released · · Score: 1

    Does anyone know a decent Windows-Linux Conversion guide which explains the parallels between the two - such as how to install drivers, where the hell is 'Program Files', what do I do if I want to install software but it's not an rpm or whatever it is suse uses. (Damn, I miss MSIs & EXEs!)

    Drivers are always an issue in Linux. You said everything works, what divers do you want? If you want the system tray config options gui chances are the hardware manufacturer does not support Linux.

    You really want to find the (preferably SUSE) RPM to install something (its much tidier) if not you generally need to follow the instructions on the website for the software you want to install. If they don't want to support openSuSE then you are on your own and need to Google for someone who has made it work.

  9. Re:Nope, I tried SuSE on OpenSUSE 12.1 Released · · Score: 2

    I am referring to home desktop usage as I assume the OP was. Such as in i don't like Ubuntu/fedora /. recommends fedora/Ubuntu and if you don't like that try Mint/Debian and if those fail well you wont like Arch/gentoo so you may as well go back to windows. Notice that openSUSE is ignored. I think opensuse should be the second recommended 'fall-back', after 'fedora/Ubuntu'.

    I didn't want to use SuSE because you did everything through their proprietary configuration interface (YaST), and I wanted to learn a more "standard" way of doing things that would apply to all distros.

    I'm fairly sure for some (possibly all Yast appears to read config files for the options) options is just a front end to a config file when you don't feel like reading the man/web page for the available options you don't have to use it but sometimes it saves time and stress.

    I assume you have never actually used openSUSE.

    Its a European distro so is never on the American "list" of distos that are recommend to try. Novel going with microsoft never helped though that's the excuse to troll it now rather than having any current justification that MS has effected openSUSE.

    Guess i should have researched it better. Wikipedia got it on Xiph's list of codecs and it is supported by the ogg tool set.

    They still would have a lot of control over it and uses for it though.

    I would think you could link ACC to the success of the iPod (helped to lock other players out and fit more music on) and thus the success of iEverythingElse.

    Outside of DD and maybe TV broadcast apple would be responsible for most of its uses (especially as a standalone codec).

    I would think a general purpose speech codec would not be so hard coded into a product it could not be swapped out in a couple of days. I dont think there is speech recognition optimisation built in.

    Unless they are going to change it (which since its still in beta they could do), its a win no matter how it got there.

    I did intend them as independent cases (Xiph created FLAC though).

  18. Re:Win for Xiph (and open source) on Siri Protocol Cracked · · Score: 1

    You miss the point, its adoption that matters. All modern codecs preform adequately considering the gains in bandwidth and storage.

    If apple end up using Speex then, in hypothetical idealist opensouce theory, the line is drawn and only companies more closed (source) than apple can use the codec which is not many.

  19. Win for Xiph (and open source) on Siri Protocol Cracked · · Score: 3, Insightful

    Appears that Xiph came out on top for speech codecs.

    This also shortly after apple realized that ALAC was going to fail (at least as a closed source product, they may push it better as an open source project now it can be played by everyone).

    They still have the very entrenched AAC though.

    I would assume those on faster plans get a throttled to a higher speed. If so that is what you are paying for no the max speed.
