New Business Card Rescue CDs

Linuxcare has introduced version 1.2 of their business card-sized rescue disks, which now contain 140 MB of recovery tools, Debian install capabilities, the X Window System, PCMCIA support, and ssh. From the picture they look pretty cool, too. I remember seeing the business card CDs at a COMDEX a couple of years ago, but this is easily the best use I've seen for them, and is a needed improvement over the previous version.

    At the most recent Atlanta Linux Showcase, the LinuxCare folks tossed one of their business-card sized recovery CDs in my bag. (Gotta love freebies.) After the initial guffawing over its size (the usable data area on the CD is only about 3/8" across), I popped it in one of my machines at home and rebooted. It turns out there's only around 32 megs of stuff on the CD, but it's enough to make a pretty usable recovery CD. (For comparison, tomsrtbt crams everything on a specially-formatted 3.5" high-density floppy.)

    One problem I had with the CD is that its size and shape makes it prone to "falling through the drive tray" when I use it in one of my SCSI CD-ROM drives. It's just small enough to slide through the slot in the back of the tray if the CD stops spinning at just the right position.

    I've been carrying the CD around in my bookbag and using it on campus lab machines. When I need to ssh somewhere, I reboot the machine with the LinuxCare CD in it, run dhcpcd, run the ssh installation script (which pulls a .deb of ssh from a foreign server and installs it on the ramdrive), and ssh as usual.

That way, when you meet anyone, just give them one of these rediculously overpriced CDRs with your info on it, and they'll also get a copy of all the non-exportables.

    Actually, the export business is getting easier now, but it doesn't hurt to put something important on them. Just think, if you were Kevin Mitnick and you wanted your data back from the feds, you could've just burned a stack of these things and mailed them to your friends. When you got out of jail, just call one of them up and have them send you your card back. With a stack of 50, the sheer volume would assure you access to your data.

    Actually that brings up another idea for these, put copies of data you need to keep and mail them to people. Or how about a distributed collection of data, each person has to provide the business card to complete the library and access the data. You could make a high-tech easter egg hunt out of this.

    Even better yet, you put the secret key to get at your fortune, spread across a bunch of these. You then mail them out to all your willed partiticpants. When you die, they ALL have to cooperate to get at your money!

    How about putting a unique key on each one of these and having people use them as access cards, you could block out specific access cards and institute your own access policy.

    This would be great for a website. You send each member a card that they have to use each time they access your website, as a password substitute.

    First, this is a complete guess.

    You notice when you burn a disc that when you look at the data side you can see where the data was written? Like if you only write 100 mb, only the first centimeter from the center is used. Well I would guess that if you cut the corners but leave the written portion alone it would work. You'd have to make sure not to bend the CD up, too.

    But like I said, this is a complete guess and I have no reason to think this would work other than it seems logical.

    Well, you guys seem to have the right ideas here but I'll post anyway, mainly because I'm a physics major and am supposed to know this stuff... :) If I'm wrong on any points here please let me know.

    There are two main types of balance: static balance and dynamic balance. Static balance is how the object behaves under a force (usually gravity) if it is not being accelerated. Dynamic balance is how the object is balanced if it is being accelerated. In our example, the CD is being given a rotational acceleration around its principle axis. Interesting side note: your auto-mechanic has to do both sorts of balance when he rotates your tires, except he probably calls the second kind "spin balance".

    To calculate dynamic balance you need to find the moment of inertia of the object. This is fairly easy for symetrical objects like normal CD's but with these weird shapes you will likely have to use a tensor and calculate moments and products of inertia. I'll make mistakes if I try to explain this. :)

    Anyways, bottom line is that it is possible to have spin balance with weird shapes. Just try to keep the principle axis in the center.

    I don't think writing random data over a disk is much more secure than writing zeros, and probably not worth it. Maybe it makes it harder for people who are trying to detect the remaining weak magnetic moments which the zeroing didn't reverse, but you could probably make that a lot harder by writing a disk full of ones after zeroing the disk. If things are _that_ important, it might be better to open up the case and trash the mechanism alignment. Then nobody would stand a chance on a modern high density hard disk.
