Knoppix Tips and Tricks
cosog writes "Robert Storey writes in a
thorough review about Knoppix: 'Some people even take a Knoppix disk with them when they go shopping for a new computer, a clever way to ensure that the hardware will be Linux compatible before you purchase it.' His article discusses things like: booting, rescuing, installing on HDD, tips'n'tricks, etc... A nice read for everyone interested in Linux (and Knoppix in particular ;)."
Knoppix really is amazing. I didn't understand all the hype before, but after a glorious performance recovering files from a horked Windows box, I make sure I always have a Knoppix CD around. Whenever Windows threatens to waste my time, its Knoppix to the rescue. Also - not only is Knoppix really good at what it does, it looks great too! Its a great way to show off Linux.
Hard Drives using the the latest IDE can get 133 Megabyters per second BURST transfers, but even good ones usually only get 50 Megs SUSTAINED transfer.
Despite your screwy numbers, Hard Drives really are much faster for loading operating systems. But the other place you screw up is that you forget what Knoppix is all about - A bootable linux distro would be a lot less convienient if you had to carry it around on a hard drive and open up computers you wanted to use it on.

Ya know, this isn't just Knoppix. People would bring in Dreamcasts with custom boot CDs, hook them up to the network, and walk away. The DC would blast a hole in the firewall, and let the hacker in.
Despite of this obvious threat, Dreamcasts were not banned, nor made to implement stronger security measures. Why? Because if any device on a network, w/o a password or any type of authorization other than its physical location can destroy a firewall, then the network itself has larger problems to deal with. To me, this calls into question the assumption of trusted devices. In short, Knoppix cannot forsee it's use, thus placing the burden on those who create and administer networks to do so in a safe and responsible manner.

FYI a 1X CD will revolve 210 times per minute at the outer edge, whereas it will revolve app. 539 times per minute on the inner edge.

Hence a 52X speed CD-ROM will revolve 10920 and 28028 times per minute on the outer and inner edge respectively
Wait. Did you just say that with a straight face, or am I misreading?
If the inner edge revolves more often than the outer edge, just how are they being held together? How many times a minute is the centre of the disc spinning?
I think you're getting velocity confused with rpms
Endless arguments over trivial contradictions in books written by ignorant savages to explain thunder in the dark.
Or you could just do it anyway. What are they going to do, kick you out of the store? *gasp*
Anyways, buying computers retail is a bad idea usually. I'm a student worker at the IT dept. of my University and it seems we're always working on student HPs and Compaqs. I'm not sure if thats because its what most people have, or if the people that need help (usually from catching a virus and/or getting loads of spyware) or if its because the machines are crap. Perhaps all of the above.
Wow. Think about what you just said. Your six year old child was able to figure out how to boot from a CD, use the KDE interface, and run and actually use Gimp. In 30 minutes. All without any help from you.
And some critics say that Linux is too complicated to be used by adult professionals in the workplace.
You obviously have a very smart son, but the point remains -- Linux is definitely ready for the mainstream, usability-wise.
Like others, I used Knoppix when I went to buy a new laptop. One problem, which the store-owner was insightful enough to point out, is that because Knoppix is intended to be a general distribution (though it supports a lot of different hardware), it might be somewhat "dumbed down" so that, although you couldn't get an ultra-new system to work immediately by sticking a Knoppix CD into it, you might be able to if you googled a bit to find the problem. In fact, though I went in the store determined not to get an HP laptop (which I had very bad experience with before), that was the only one with my desired specs which would boot immediately from the Knoppix CD (some Sony Vaio and another brand didn't boot). It might be that I saved myself a lot of trouble by avoiding those machines, but then it might just be a simple problem with Knoppix itself not yet supporting the hardware.
What's really gonna bake your noodle is can you write to anything other than a pre-existing file or change the size of a file? I'm afraid your noodle's cooked.... because it doesn't. To quote linux-2.6.0-test11/fs/Kconfig ....
config NTFS_RW
bool "NTFS write support"
depends on NTFS_FS
help
This enables the partial, but safe, write support in the NTFS driver.
The only supported operation is overwriting existing files, without
changing the file length. No file or directory creation, deletion or
renaming is possible. Note only non-resident files can be written to
so you may find that some very small files (
It is perfectly safe to say N here.
