You could have a look at xldlas:
Name : xldlas Relocations: (not relocateable)
Version : 0.85 Vendor: (none)
Release : 5 Build Date: Sun Nov 15 15:42:10 1998
Install date: Fri Aug 4 00:14:35 2000 Build Host: yankee.localdomain
Group : X11/Applications Source RPM: xldlas-0.85-5.src.rpm
Size : 290017 License: GPL
Packager : Matthew J. Saltzman <[EMAIL PROTECTED]>
URL : http://a42.com/~thor/xldlas
Summary : a basic statistical package for X windows
Description :
Xldlas is an X11 based statistical application with graphing, regression
analysis, curve fitting using genetic algorithms, and some other useful
stuff. It was inspired by a non-X11 statistics program called ldlas,
which stood for ldlas, damned lies, and statistics. So, I guess xldlas
stands for x ldlas, damned lies, and statisitics. Xldlas uses the xforms
package. This RPM distribution assumes you have release 0.86 or newer.
Xldlas is the work of Thor Sigvaldason, <[EMAIL PROTECTED]>. For more
information, see the xldlas man page, the online tutorial, (accessed
from the help menu at the upper right), or the xldlas home page at:
http://a42.com/~thor/xldlas

Um, Slackware and fvwm95. Still great after all these years.
Gnome and KDE are getting all the buzz nowadays with regard
to being complete desktop environments. I use KDE from time to time but
frankly prefer plain ol' fvwm2 on top of XFree86.
IMO the currently popular distros like Suse, RedHat (and its offspring
Mandrake), Caldera, et al. seem to have gotten really, really, eye-opening
and jaw-dropping big. Suse especially. Installation becomes very
time-consuming through trimming out all the nonsense --package by
package-- that you don't want to install. These .rpm distros are, however,
a lot easier to upgrade and keep current than old-style Slack ever was.
Slack, Debian, and some others seem much quicker and easier to keep within
reasonable compass, plus you don't find yourself in mortal combat
constantly with some all-encompassing proprietary configurator tool every
time you wish to some perfectly simple configuration change or bit of
system administration. Slack now recognizes the existence of rpms, but the
preferred method of modfication is still the old package installer. There
now exists a freeware upgrade utility called slackUp (available from
freshmeat) that will upgrade a slack system from whatever it is to
"current", similar to the rpm upgrade stuff that Suse et al. uses. slackUp
actually works quite well, except that it seems
inexplicably to miss some modules when it upgrades a kernel, which modules
end up having to be added manually after the upgrade.
But hell, it's all Linux; it all runs great regardless of distro once you
get it hammered into your desired shape. Get one of the cheap
Mondo-multipacks from Linux mall or wherever, and play with a few of the
current-issue distros for a couple of weeks until you find the one that
seems best to fit your current needs.

We have a number of users running Linux 6.2 who telnet to an SCO 5.0.5
server, then open scoterms on their Linux X displays. This works
perfectly except for one problem: Neither the numlock or the capslock
have any effect in these windows.
Caps/numlock work fine in local windows (xterms) and scoterms open on
another SCO server work fine.
Can anyone give me an idea where to start working on this problem?

Your soundcard is probably soundblaster compatible so you should configure

The administrator who wishes such a policy (which it is: a policy, not a

This would be nice, but under certain weird circumstances the user
copying to the media may not be in control of the media. Technically,
removable media should be lockable such that someone with access to the
media cannot remove it while it is mounted.

Subject: Re: Linux dedicated UT server vs. Win32 dedicated server ?
Date: Fri, 08 Sep 2000 23:04:33 +0200
An NT server will need 24MB of RAM without any other services.
So that leaves you enough memory for the UT server.
A P133 is believe it are not (I probably get flamed for this) will perform
probably out perform Linux
when this is the only service running. NT has a minor and that minor can be a
plus, is that it gives alot of resources
and cpu time to a process when it is running almost alone. This could speed up
your server pretty much.
The NT ip stack is also unfortunatly "still" better then the linux ip-stack.
That chokes with a lot iof small requests which a game server
happens to send. The Multithreading IP stack in NT is very flexible. Linux is
getting there to with the new threaded ip-stack.
In that case Linux could well out perform NT on network level since the rest of
the linux system is alot slimmer.
So I think that since this is the only process running that NT will improve
speed over 5 to 10%. I don't
want to talk about stability here :-) An occasional blue screen can happen.
Linux might not be as fast as NT but it sure as hell is more stable.
And if the other readers wanna flame go ahead, but these are the facts I can't
help it.
I'm a Tru Unix and Linux lover, but NT performs a bit better. In single process
situations since a application
can clame almost all CPU time, I see this as a major flaw in the design of the
multitasking since a crashing process
can stop a complete server.

So permit me to restate:
The term "end-user" encompases all users as all levels of experience and
abilities. Neophyte or beginner are better terms if you are referring to
less capable users. Of couse it is possible that a neophyte may never
outgrow that catagory.

A Parallel Oracle Cluster is still impossible right now with Linux
due to the lack of a Clustering File System that allows several servers to
write on the same
data at the same time. This could soon change with the CFS project which is
prommising.
No you will have to do with a standby cluster with a read obly snapshot. In my
eyes
a standby sluster is no cluster since you still have downtime (for rebooting
services (like oracle in read-write mode), mounting shared storage). With a
real cluster
you will not notice any glitch except for having to reconnect to a server in
the worst case.
A warm or cold failover is pretty easy. It can be made with some trivial shell
scripts.
There are many of these going arround, failoverd is one of the, See

You mean like the floppy drive on the Mac? I've always hated it's fascistic policy
of not being to pop out the floppy by pushing a button, but for *nixes it makes

I got a similar problem. Just installed RH6.2; selecting gnome, which was
too slow, so I changed to fvwm2.
If I mount 'other' partitions (FAT16 and an old linux one), then
the X screen just shows the "grainy pattern".
I also traced this by restarting. Then I noticed the problem only occured
after I mounted 'other' partitions.
It's a pity that Linux is chasing M$cartoon-style, instead of building
reliability. Ease of use is best obtained by mc (midnight commander)
type interface. The complexity introduced by gnome , must introduce
errors. Apparently kde is worse ?

Date: Fri, 8 Sep 2000 23:33:40 +0200
While I was reorganizing my backup (using a CD-writer), I had the idea
of using an ISO-9660 image file mounted through the loopback device. I
soon had to learn it won't work the way I liked since ISO-9660 is simply
readonly.
I think it's time Linux gets the ability to use writable image files, so
I'm going to make the following proposition:
1. Creating a writable ISO-9660 compatible fs (I'm calling it isorw)
- mounted on a writable device, writing/deleting/etc is possible
- written on a CD, it should be readable as if it were ISO-9660
- capable of Joliet and/or RockRigde extension
2. Creating tools to handle isorw
- kernel device drivers, readable part might be identical to ISO-9660
- mkimage for creating image files
- possible extension for CD writing programms
Q: Why a new filesystem
A: Sofar there is no fs for Linux which is writable on a disk and still
ISO-9660 combatible on a CD. Of course a writable image could be made
with ext2fs but it always needs special treatment if written to CD.
Q: Why ISO-9660 compatible
A: For archiving puroses (storing and retrieving on CD's for serveral
years) there aren't many alternatives. Vfat is one but not very
attractive to me. UDF might be another in a few year but not now since
not many computers can read UDF.
Q: How complicated is isorw
A: It depends on the way it's implemented. The reading part could
possible taken from the ISO driver. The writing part might be implementd
along the line of ISO-9660 Level 3 (as Rod Smith kindly suggested). IMHO
although I haven't read yet it I think it's doable.
Q: Why not simply changing the current ISO implementation.
A: This shouldn't be changed since lot of people needs it working.
Anyway if isorw is working it might be merged in later on.
Q: Could isorw be used on other systems, i.e. Windows
A: Of course but only readonly as an ordinary ISO-9660 file unless isorw
is implemented there as well.
Q: How about Joliet format
A: There shouldn't be a problem with Joliet and/or RockRidge extensions,
it should be handled as usual.
What are you thinking about my proposition? Could this be done or are
there obstacles I don't see. Is it alltogether not necessary, because
there's a much better solution?
Is there anyone who is interested in isorw as well and likes to help me.
I'm currently not a Linux/Unix developer, I mostly programmed on TANDEM
computers.

The linker cannot determine if libm is required or not.
If you call printf then you may want to print a float
or you may not. The format string does not have to be
a literal constant; it could, for instance, be read
from a file at runtime.
Nowadays the basic floating point functions such as
addition, multiplication, division etc are not part
of libm, they are part of the processor instruction
set; but if they have to be implemented using
integer arithmetic they can take up rather a lot
of memory.

IIRC you have to compile the locale using localedef which comes
with glibc.

Woops, Wander then wonder. Include www.mips.com,
www.mot.com, www.ibm.com, www.arm.com and even www.ti.com in
the list. There are some cool part designs out there.
