    Personally, I think the rental company's being more honest than the cops -- most speeding tickets are handed out to enhance city revenues, not enhance motorist safety. At least the rental department's being honest about it. ("It's got nothing to do with the police, we just want the money")

    > As I recall, on the big, nearby Supernova 1987A, a neutrino burst was detected. My question is, did anyone get the timing nailed down from this event well enough toconfirm that the neutrinos were a little late?

    I don't think we really knew when we SN1987A visibly started brightening - IIRC we saw it after the fact.

    In any event, given that neutrinos could pass through the shell of the star faster (i.e., almost the speed of light) than the star could tear itself apart (i.e. minutes/hours), I'd expect the neutrino burst to be observed before the light from the supernova.

    (That is, the light travels faster than the neutrinos, but the neutrinos get out of the supernova before the shock wave hit the star's surface.)

    Come to think of it, if I were running SNO or Super-Kamiokande, and I saw multiple events all within a few seconds of each other, I'd eliminate the possibility of detector error ASAP, and then look at the angle of incidence (all the neutrinos would appear to be coming from a point source) and start phoning every telescope operator on (and off :) the planet to look in that general direction for something going boom.

    Great, all I need is a piece of lead several light-years thick, and I can then melt it down and extract the at-rest neutrinos to make neutrinonium (as long as I'm fantasizing, I wonder if a lump composed of neutrinos at rest would shimmer or somehow change color as the component neutrinos oscillated between three states ;-)

    1) You're right. There's probably a much greater security thread from spyware that comes with things like RealPlayer, and/or users installing stuff like AudioGalaxy or Comet Cursor, etc. on their machines.

    2) He's also right. Maybe for the TVA, this is a little paranoid, but a keyword search on "covert channels" provides some insight.

    Suppose you were a KGB agent assigned to find out when the TVA was most worried about blackouts. You'd be very interested in knowing when large numbers of TVA employees were working overtime at the head office.

    Rather than hax0r the head office's computers (exposing yourself to risk), or have an agent staking out the head office (exposing the agent to risk), you'd just eyeball SETI@Home's publicly-accessible stats.

    You could then deduce that something was FUBAR in Tennesee when "Team TVA", which was churning out one unit every 70 minutes from 5:00pm to 9:00am, dropped their stats precipitously - say, damn near nothing getting done until 11:00 pm, one unit every 120 minutes from 11:00 pm to 1:00am, and only going to the "regular" 70 minutes per unit from 1:00 am to 9:00am.

    In fact, in the simplified case I've specified above, you could not only make an educated guess as to how many employees were working overtime, and for how long, you could even make an educated guess as to what hardware platform was being used by The Guy Who Stayed Until 1:00 In The Morning.

    Like I said, for the TVA, this is probably paranoia. But for other agencies, information leaked by covert channels can be deadly serious.

    (In business too -- at a small enough company, suppose you saw similar data patterns and you knew what CPU power the CFO's PC had. If the CFO's up all night, every night, on the last week of the quarter, maybe he's desperately trying to make up the numbers. Such information could be worth millions of dollars, and it wouldn't even be insider trading, because you're only making an educated guess based on the working hours of the CFO.)

  8. Re:MP3 or OSS formats on AOL, Microsoft Squabble Over Control of Online Music · · Score: 5
    > I guess mindshare is everything... and MP3 has it. Sorry AOL/MS.

    That's the part that still scares me.

    If MS really wanted to take over the world, they'd do to MP3 what they did to AVI.

    That is, they'd use the same file extension to represent dozens of codecs, many of which were proprietary.

    Download an arbitrary .AVI and ask yourself what you really have. It's pretty tough. YUV? IV31, IV41, IV51? 2.63? MPEG4v2? MPEG4v3? DivX ;-)

    Attempt to play an AVI with even one byte screwed up in Windoze Media Player, and it says "Nope, I won't even show you the video up until the corrupt part." (Sometimes you can get around this with File->Properties->Preview in the 'doze explorer, which just shows how brain-dead WindozeMediaPlayer is).

    So WTF does this have to do with MP3? Plenty.

    People like to swap files that end in the .MP3 extension. All Bill has to do is pay Thompson enough money, and buy the right to stuff whatever crap he wants into a file ending in .MP3, and stuff whatever brains he wants into Windoze Media Player to say "Ah, the file ends in .MP3, but it's actually a WinMedia or RealVideo file. I'll decode it accordingly".

    On the encoding front, it'd be easy for him to do the same thing - MP3Pro (different codec, same file extension, albeit with some backwards compatibility) from Thompson is already doing this. Bill could make his "music recorder" tool record in a proprietary codec, but save the file with the .MP3 extension.

    Within a month, clueless luzers would flood the pool of MP3s with these Windoze-only files that happen to end in ".MP3", and we'd be in the .AVI situation - "Damn, this thing won't play, what the hell codec do I need today" all over again.

    With .AVI, it was inevitable, as we had CPU speeds going from 16 MHz to 1.6 GHz - a factor of 1000 - and similar growth in hard drive sizes. We really can do better video today that we couldn't have fantasized about when the first .AVI codecs were introduced.

    But music? No thanks. MP3 at 320 is indistinguishable (for me and anyone I know) from CD. For most folks, MP3 at 192 is "good enough". For anyone - by definition - a lossless compression of the original .WAV is "perfect". We already have most, if not all, of the technology we're ever likely to need when it comes to "How can I make this compressed bitstream sound like the 2-channel stereo recorded on this CD".

    All that's left is to screw it up by embedding it in various DRM schemes. I dunno about you, but I think I'll pass on that.

    Huh?

    It's a packet sniffer. But you have to have physical access to the ISP's datacenter to use it.

    The real question (arguably unanswered) is whether or not the part of your TCP/IP connection between your home and the first router away from your ISP constitutes part of your home.

    The argument can be made that it does - they could just wiretap you. But they don't, choosing to use the ISP's outbound pipe to wiretap everyone and (so they tell us :) then throw away the data from everyone but you. They do this for the sake of convenience (It's arguably harder to wiretap a cablemodem. Or optical fiber to the home. Or line-of-sight laser to the home...).

    That is, Carnivore is just an easy way (using means not available to the general public, like sitting down in an ISP's datacenter) of getting access to your data stream (which is information they would not otherwise be able to gain without having to) wiretap you (which would typically require physical access to your property or the wires/cables/lasers/EM-fields connecting thereto or emanating therefrom).
