Recently I received a Zaurus machine and reflashed it with the pdaxrom image. However, I find almost every image for the Zaurus a bit inadequate - getting used to Debian on the desktop makes it frustrating not to have 10000 apps apt-get'able at your fingertips.
However, I did manage to manually bootstrap a ARM-port of the Debian system over NFS and later downloaded it to a sundisk. I simply chroot to it, and then I have all I need including apt-get.
There are some web pages that describe how to use Debian on the Zaurus, but I haven't found yet anything that has ready images and easy installation.
For me, one of the most rememberable moments was watching Alan Cox and another guy whose name I've haven't noticed, playing an identify-the-os game with the KDE BSOD screen saver.:)
Thanks for the elaborated explanation. I noticed that a lot of people have a hard time understanding exactly what coLinux is. It's easy to get confused with all the other virtualization methods that are around.
I just want to add some of technical details to what you wrote. First, one of the main reasons that coLinux runs in ring0 is to have control over the MMU (memory management unit), so it could do whatever it wants with the subset of the physical memory that is specially allocated for it.
In its running context, coLinux avoids as much as possible from asking the CPU to do I/O operations. Actually, the only I/O operations that it does are involved with getting values from the high precision timer. This means that all of coLinux's drivers are harmless and depend on the services given by the host side. You can think about coLinux as a 'Super' process, a process that can do anything a kernel does, but it avoids accessing the hardware directly and instead it interfaces with the other kernel in order to get what it needs.
People need to understand that unlike VMware, coLinux is 100% pure native execution. It's not a trap-and-continue-based virtualization. That's the reason it has the potential to be faster than any other virtualization method.
Ya' know, every once in a while they come up with an entirely new scientific excuse for global warming. Finally I'd get tired of this and begin to ignore all what is said about global warming.
The Sun is gonna get larger, starting to fuse helium, then beryllium, and finally burn the Earth in about a few billion years, so who cares anyway?
The 1.44mb diskettes technology is really below the standards of today's computing.
Not even that you can't put a single average MP3 on it, there's a huge chance it would get corrupted with bad sectors.
Nothing justifies the existence of that technology in new computers. Almost everybody have E-Mail addresses today, so sending something as small as 1.44MB to someone is really quick and doesn't require a diskette.
What people worry about is that the body might be more than a mere collection of particles, perhaps also contain some sort of a soul, that your being, and notion of 'self' is not only defined by the mass you are composed of. Think OOBE.
Imagine that the source of the teleportation was not destroyed - this means that an entirely new copy of the person was created. Which one of the people is considered the real person, if the duplicate is indistinguishable from the source? If we kill the source or the duplicate, did we affect in any way the alive-or-dead status of that person?
Perhaps only if the operation of creating the destination and destroying the source is being done in zero time, you can define it as movement.
Yes, if you don't want the old pictures to look
yellowish in about 50 years or so. Also If you wish not to lose the only copys of your old photos in case your house burns down or something like that. I strongly recommend to digitize the albums. The same goes for home videos, which are recorded on a magnetic tape.
Though, there are number of points:
1. If the time doing all the scans, or maybe if buying a scanner is unwanted, you can pay someone who has a very high quality scanner to do the scans for you.
2. Make sure the photos are scanned in a satisfing resolution (i.e, like 2400x1600, using 3 bytes per pixel).
3. Make a lot of digital copies of the albums. Put these copies in different locations.
4. Use different storage medias (tapes, CDs,
Internet file servers, hard drives), so in
case one of them ceased to be exists or ceased to be supported when new hardware doesn't read old media in the not so far future, you can always try the other mediums. AFAIK, burnt CDs may become unusable after 50 years even if not used.
5. Save the original albums, just in case, so that your old 90 years old grandmother wouldn't need to tackle your Linux box in order to browse the photos...
I really don't like the idea that by mistake, my relatives, friends, or colleagues on the Internet will get this kind of E-Mail by mistake:
"This is an automated message. If you read this, I am probably dead. My will is to be burried along with my hard drive, and send the rest of my computer hardware as donation to Linus Torvalds."
On the first time they get it, they may get paniced, and set up a funeral for me while I am away.
On the second time, I'd really drop dead and they'll laugh and ignore while I rot on my keyboard for months.

I hope it doesn't come with odors.

That's not the right attitude (nor place).
Stop ranting and start debugging (or grab the closest hacker near you to do it).

No need. works great on WINE.
That's not true. The kernel still reports HZ=100 to userspace, and as far as jiffies calculation concern toward userspace, nothing has changed.
My point is that individuals and companies are aware to Linux's robustness, and are willing to pay.
Take VMWare for example. The Linux version is not only full featured, but is actually more robust and rigged with stuff like SCSI emulation.
