8/7     My grandmother has an original iMac that she is donating. She
        wants to erase the hard drive before it leaves her
        house. What's the best/easiest software for doing this?
        (she just upgraded to a iMac G5).
        \_ Get a firewire cable and plug the old iMac into the new one.
           Place the old iMac in firewire target-mode by holding the
           Place the old iMac into firewire target-mode by holding the
           letter "T" during boot. Then you can reformat the drive
           by using Disk Util on the new iMac. On Tiger, there's an
           option of wiping the disk with zeros several times over
           but this will take a while.
           \_ Original iMac doesn't have Firewire and can't run tiger.
              I'm thinking maybe she can boot the debian installer CD
              and run dd. Any ideas?
              \_ You only need tiger on the host computer, not the
                 target. You could always just yank out the disk
                 and put it in another computer where you can run
                 a disk zeroing (or randomization) util on it.
           \_ Wouldn't random bits be better than zeros?
        \_ Can't she use the MacOS install boot disk and run disk utility?
           \_ Does OS 8 Disk Utility have a way to zero the drive?
           \_ I found knoppix for powerpc. It is a couple years old
              but should be okay:  http://debian.tu-bs.de/knoppix/powerPC
        \_ if you can boot a linux, *bsd, etc. off live CD, the "shred"
           command is pretty convenient.  it make sup to 25 passes, so
           most likely you'd only let it go once or twice unless you
           have extreme security concerns.  works on block devices or
           on regular files.

12/21   In Emacs, how do I make it so that it will resize its screen

        reliability-wise and if they have better suggestions. I have about
        $400 for this.

        (between an external hard drive and my computer), which one is
        better and why? Thanks.
        \_ Firewire is faster and more robust for that application.  USB
           is more widely available if you'd ever want to move the disk to
           another machine.  -tom

        it shows BIOS, but it won't show the WinXP screen.  So, it sounds like

        assume it's a virus).

2/3     So, I'm really confused about this notion of computer science
        metrics where everything's kind of 2^n, but sometimes not. For
        example, if I have a 4 GIG hard drive, does that mean I have
        exactly 2^32 bytes of space? Does that translate to 4000000000
        bytes, or some number that's close to it? How about megahertz?
