I've also enabled Write cacheing on both drives. That, from what I
understand, can cause data-loss after a power failure, but I'm going to
test it for a while and see if performance improves.
The above 57.66 number seems a bit interesting to me - both drives DMA
buffers read at the same speed? Is that normal?
The info on my drives looks like such;

I'm now using all of those settings. It appears as if my Sector Count was
already set to the MaxMultSect value for both drives by default.
>The figures are even better with the 2.4.x test kernels,
My kernel version is in my .signature. I must say I'm quite impressed with
the performance of these drives, if those figures are correct. I'm going
to reccomend some of these settings to a friend running a UDMA66 drive and
see what numbers he can come up with.

Oh? I've noticed snappier performance since switching to 2.4. Memory
management appears to be much better, and disk cacheing is greatly
improved.
"Ongoing VM problems"? Would you mind elaborating?

I dunno, that's just what hdparm tells me. Since applying some of the early
tweaks to my HDD's, moving 3-6MB MP3 files between drives/partitions has
GREATLY improved. I'll have to try moving a 300MB VMWare .dsk file around
and see how fast MC tells me it's moving.

Copy everything off of it, being careful to read the man page of cp to
copy all file permissions, to a temporary holding directory. (I used
/var_temp, a directory created within the / partition). Umount the
existing /var partition and kill it with fdisk. Create a new /var partition
of the desired size (this may require deleting/resizing/moving other
partitions around, which can be done with PowerQuest's Partition Magic;
I just don't trust it completely with ext2 partitions).
Once you've created the new partition, create a filesystem on it (man mke2fs),
mount it, and copy the files back (again being certain to maintain file
permissions) and you're ready to roll.
I modified my /var partition as mentioned above on a running Linux system
(name, proxy, web, FTP, SMTP, POP3, NTPD, etc..) without having to reboot.
Good luck - and be sure to read carefully all man pages along the way!
Losing your /var partition can be hazardous to your health. ;>

The script below could let one adjust the peak levels of the
files to all be at maximum. But, peak level is *NOT* a good
indicator of listener "volume". Rather, RMS amplitude is a
better indicator of listener volume. Recently RMS amplitude was
added to sox's "stat" feature. I forget the first version number
to include this new feature, but it's definitely in 12.17.
Here's a sample of the new stat output.
Samples read: 27378806
Length (seconds): 620.834603
Scaled by: 2147483647.0
Maximum amplitude: 0.946472
Minimum amplitude: -0.912659
Mean norm: 0.062141
Mean amplitude: 0.000117
RMS amplitude: 0.091823
Maximum delta: 0.806030
Minimum delta: 0.000000
Mean delta: 0.041814
RMS delta: 0.061465
Rough frequency: 4698
Volume adjustment: 1.057
The script below should be coded so that the file with the
largest "Maximum amplitude" is increased in volume by its
"Volume adjustment". After that, the rest of the files should
be increased in volume so that their "RMS amplitude"s match that
of the first files new "RMS amplitude". This will be a good
starting point for equalizing the perceived volumes.
G'luck...

Gnome (1.2, at least) uses three subdirectories:
Program Settings: ~/.gnome/
Desktop Icons: ~/.gnome-desktop/
Stored Passwords: ~/.gnome_private/
(and, of course, that last one is chmod 700)

Of course it is, but that has nothing to do with free vs. proprietary
software; it's a matter of frictional losses in retraining on anything.

Fine. Let's skip "free speech", then, and say that "free software"
refers to "liberty of code". "Free speech" is merely an analogy, anyway.

I can't get my LInux 6.2 to get on the network. Can't ping anything and
can't ping the box from another pc.
Looking at the /var/log/messages, when it loads the Cyclone driver for my
3com Fast Etherlink XL PCI, it says "might not work on IRQ=0" and it does
try IRQ 0. How do I change it to IRQ 11 (which is what I think it should
be)?
Probably a easy programming answer.

Right now, as a student about to graduate from university, I like to
keep a competitive edge over my classmates. I learn cutting-edge,
high-demand languages (especially related the Web development world,
**except** for ASP...), and I learn all about networks and system
administration (particularly UNIX/Linux). I'm even thinking about
working through a Linux certification course.
I could forsee that my competitive-edge-itch will probably become simple
curiosity in the future (i.e. I wonder if I can do this, or I wonder how
I can to do that) because I'll be learning everything I need to know for
my job on the job.
The other aspect of it (which will never fade) is sheer exploratory
science--diving into an unknown world and discovering things as if they
have never been discovered before. Linux was **COMPLETELY** foreign to
me when I dove in head-first four years ago. Since then, I have amassed
more knowledge than I probably care to know, a lot of which has come out
of resources like this newsgroup and other online resources. As I
continue to use UNIX/Linux regularly I'm discovering more and more about
it.
And yet another aspect of it is genuine interest. I find reading about
networking rather fascinating. Just the fact that a team of people
invented this thing called the Internet about 30 years ago boggles my
mind. And to see where the technologies have gone since they were
invented is even more fascinating, and then imagining where they might
go....
In a nutshell, to me at least, having this kind of motivation is an
"acquired taste". Most of my friends don't/can't understand how I can
be interested in all the things I'm interested in. Once a person gets a
taste for something they can be really passionate about, it really
starts to make sense. They just have trouble extending it to
computers. :o)

Hi everyone,
I thought the following problem would be already solved.
But now I'm sort of loosing hope.
I want to backup 2GB data into several CD's. Ideally
ther would be a way for me to
1) Compress the files before writing
2) Split the resulting strucutre into 650MB
I tried using the -L option for the gnu tar
to no avail. This option seems to make sense
only when writing to tapes.
compressing would be easy, I just need to duplicate
the data before writing, but I don't know
how to split the data into chunks in order to
use mkisofs. Maybe I'll need to write my
own script ?
thanks all of you
Julio

Also, are there any utilities that can do a GUI removal or uninstall of

The file was a download from the Redhat site (powertools 7 beta). I can

Sounds good, but unfortunately all the documentation is code - there is
no documentation, help files, etc. Even the README is dedicated to
describing compilation and installation. No errors during the cdrecord
run. So, clue me in: how do you specify an image file to be used with
xcdroast? Or does xcdroast feed a command line to cdrecord that is
substantially different from the one I listed above?
