  1. Re:how they do that? on VMSK/2 Promises 5 Times More Bandwidth · · Score: 1

    I seem to recall that a large part of the secret is phase modulation. (erm. although that may be my star trek fixation talking.)

    I have vague recollections of polar plots (phase and amplitude). Each pulse is a point in this graph. Depending on how good your circuitry is, you can discriminate finer and finer regions. Ig you have 8 regions, you send 3 bits per pulse.

    So if you believe that as a very rough sketch, you can extrapolate that better phase/aplitude detection allows you to discrimnate 2^19 regions. Hrm that sounds like a lot. Maybe not; assume 8 bits amplitude, that leaves you 2^11 bits phase, which you can do at 2048 hz sample rate.

    How they then go to 2^90 regions... that I leave up to the experts. or better bullshit artists.

    Does that make sense to anyone?

  2. Re:It all comes down to reputation on Real-time Video Disinformation · · Score: 2

    That is a bit disingenious. Afterall, the underlying assumption is that the signals will be digial. Thus, the talking head can be watermarked (and thus signed) separately from the PIP graphic in the corner. Furthermore, the composition could be separately signed.

    As we move to product placement, it would be easy for the product-placement part to be signed by the manufacturer, and the rest of the sportscast by ESPN. Just like HTML pages, the client does the superpositioning. It is the obvious way to go.

    I'm not so sure I buy that, as the major reason why sony (and betamax) lost the video wars was that they refused to let pornographers licence the medium.

    Now for VHS, exactly what you said applies, but that was a consortium (zaibatsu?) lead by (erm, memory, don't fail me now) panasonic.

  5. Re:SCSI sucks for home use. on A Look At the Fastest IDE Drive Yet · · Score: 1

    You're forgetting one thing...

    I had to give away a 2gigger segate (this was back when that was niiice) cause that thing sounded like a fsking jet engine when it span up. My then SO had definite views on late-night noise pollution, and that drive didn't cut the mustard.

    At first glance this isn't directly related to SCSI, but they tend to 1) run at higher RPMs and 2) be optimised for server use so not have as much sound insulation (perhaps also because that would insulate against heat, and SCSIs run hot?).

    Anyways, for home use, they're too damn loud.

  6. Re:Shannon's delight on Fiberless Optical Networks · · Score: 2

    Hrm. Lasers are inherently polarised. How easy is it to switch that polarisation and to transmit (say) error correction in the polarisation, information in the carrier?

  7. Re:Solution to the bird problem. on Fiberless Optical Networks · · Score: 1

    sure, you have to use encryption, but you'd have to do that with an IR or even over the wire network too. A visible laser network is probably more secure than a bog-standard lan, as it brings security (visibly) to the foreground.

  8. Re:Navy radar and mess deck food on Fiberless Optical Networks · · Score: 1

    Well,

    old radar used to be (still is?) microwave, so I've heard similar stories of foxes/cats coming to feed on the birds microwaved near commercial airports.

    However, given that the mast probably was metal, it probably would have been a bad idea to microwave it. (visions of tesla coil lightning bolts arcing from the mast...)

    I always thought big carriers should supplement their food by fishing. Does anyone know if they did this in the bad old days of sailing ships and salted meat?

  11. Re:me ? on KDE Developer on the GNOME Foundation · · Score: 2

    You're right...

    in a way. How many people here actually want desktop integration? I know that i don't. I like having to start programs on the cmd line and not having things happen by default.

    Take redhat; I recently installed it on a laptop, and first thing I had to do was to figure out how to disable that crap gnome/enlightenment environment and just get a normal window manager up and running. one without fsking session management. I get really uncomfortable when I have to trace four layers of scripts to figure out why this and that program was started.
    Magic is great in fiction, but I hate it on my desktop.

    Ok, in retrospect I perhaps shouldn't have chosen the gnome workstation install, but I wanted the libraries installed.

  12. 2d shooters kick ass! on Vanishing Game Genres · · Score: 2

    yes!

    I have been looking for a good sidescroller for years! The amiga had one -- R-type I think -- that was absolutely brilliant. The C64 had Delta I think it was. Both kicked serious butt.

    More rencently, (like three years ago) I bought (one of three software packages ever purchased) battlegirl, which was totally kick ass. As soon as I get my hands on another mac, I'll dust off the zip disk it is installed on. It had a top view 360 scrolling action, with 100s of levels, and best of all, separate fire and fly controls (like Bolo for the Apple II).

    Does anyone have any good 2d shooters to recommend?

    Hrm.

    yes. that does show a disturbing lack of logical reasoning -- partially on your part but that's ok as you're not paid to reason logically (sorry 'bout the unavoidable flame, but I'm making a point here), and more disturbingly on the judge's part, as he is paid to.

    spot the error:

    A thinks X
    B thinks Y
    on issue Z both A and B agree
    hence A thinks Y.

    'twas good, all in all.

    On a similar vain vein, wasn't there a Science / Nature / samerican article about living forever? The problem is that the universe will eventually contract, putting an upper bound on how long you can live. IIRC the authors were speculating about time expansion effects after the crunch, (kinda like zeno's paradox, or the black-hole effect in reverse) allowing you to potentially live forever on the edge of a constantly expanding bubble.

    or something like that. Anyone care to hand me a clue?

    Blood doping is a well known technique. Take blood samples from yourself, refine out a red rich mixture, and freeze it. Inject it back into yourself before the event. Eventually, your body absorbs them (or they just die, I forget), but for a while you have great aerobic transport.

    Of course, it is unethical and grounds for diqualification. The problem from a testing standpoint is that it is hard to distinguish from having trained at high altitudes, which is perfectly fine.

    Don't know about energy consumption.

    As for this chip, I was suprised that the cache was responisble for such a large part of the energy load. Isn't it possible to turn the cache off by software on some chips?
