  1. Re:SVHS should be better than composite signal.... on Xbox Price Drops For Australia And Europe · · Score: 2
    Speaking of picture, it should be better looking since the cable called SVHS is always better than composite because it uses 2 cables in fact, a Yellow and a Cyan signal. Thats why electronics and TV guys call it Y/C.

    Actually, Y/C is luminance (black and white part) and chroma (color part). I don't know why luminance is Y :)

    And component video is Y/Cb/Cr--luminance, and two color difference channels (Blue - Y and Red - Y).

    Halon will kill you very quickly

    Nice unsubstantiated claim there...

    (speaking as one who is trained to fight fires including the use of installed Halon systems)

    Oh, appeal to authority too... good one! Got Documentation(tm)?

    (And as I posted above, people have been in an accidental Halon dump (no actual fire) and sufferred no ill effects).

    The way Halon puts out a fire, quite simply, is to smother it

    If that were the case, how does it manage to work in such low concentrations? It shouldn't be any better than flooding the room with CO2, nitrogen, or some other gas that doesn't support combustion. Tell me, what's the minimum concentration of CO2 needed to put out a fire? At least 34%, perhaps? How about Halon 1301? 5% or so.

    I didn't say that it was perfectly healthy to inhale for extended periods of time. I said that the concentration required to extinguish a fire leaves more than enough oxygen to breathe. It won't suffocate you. No, you won't die if a Halon system goes off when there's no fire. Yes, as I said, the decomposition products when there is a fire are quite nasty, but the decomposition products of the fire itself are probably even worse.

    as well as many floors' worth of people who'd have died of suffocation from the Halon.

    Why would anyone die of suffocation from Halon? That seems to be a very common myth... Halon doesn't do its thing by keeping oxygen away from the fire (and humans)--it works by reacting with free radicals in the flame and stopping the chain reaction of a flame. The concentration of Halon needed to extinguish a fire is low enough that there's still plenty of oxygen to breathe. Of course, the byproducts of Halon's reaction with the fire are rather nasty and toxic, but the consensus seems to be that they're no worse than the products of burning plastics and whatnot. I.e., it's better to put out the fire and make a bit of HBr in the process than to let the fire burn for an extended period of time (Halon puts out a fire pretty much instantly. I've heard it can even stop an explosion in progress).

  17. Re:Predictions copy management on Next Windows to Have New Filesystem · · Score: 2
    The point is there should be no such concept as "permission denied" for an administrator.

    But I thought you just said that it was a nice feature that in various flavors of Unix, you could set a file to be immutable so that even root couldn't delete/change it:

    But root can redefine it so it can be deleted, right? That's a nice feature. Doesn't change the point.

    Of course, it's possible to take that flag off if you boot into single-user mode. That's even more restrictive than in NT, where you don't have to boot into any special mode, you just have to give yourself permission. So either Unix root is even less powerful than NT Administrator, or they're both all-powerful. I don't care which you pick, but you have to be consistent--you can't say that Unix root is all-powerful, but NT Admin is weak.

    Real simple fix. Don't use 7,200 RPM drives. Buy 5,400 RPM models. [...] And cheap SCSI drives do not cut it [...] you need to pay for a higher end model.

    Isn't that sorta contradictory? Where can one get a "higher end" 5400 RPM SCSI drive these days? It's getting hard to find even 7200 RPM drives. Personally, I'd like to get 3 or 4 18GB 7200 RPM SCSI drives for my home file server/mail server, but then I look at the price of an 80GB 7200 RPM IDE, like Maxtor's DiamondMax and think that SCSI is way overpriced these days (seems like the price differential between SCSI and IDE was smaller five+ years ago).

    Anyways, I'm a bit of a SCSI zealot, but have bought IDE drives recently because of the price... got a 45GB IBM 75GXP which has developed some bad blocks :( However, I've also had a 2GB IBM Ultrastar DFHS, a 4GB Quantum Atlas, and a 4GB Quantum Viking go bad. Plus a 105MB Quantum LPS with its infamous stiction problem. And a 80GB Maxtor external Firewire drive (which is just their standard 5400 RPM IDE drive with a IDE to Firewire bridge).

    On the other hand, I've got a 2GB Quantum Capella that's still going strong after about 7 years, some sort of 120MB IDE Quantum drive that's older than that, and a 540MB SCSI Quantum Fireball, which are all doing fine.
