Yeah, you figured out what he meant and I figured it out, too, but
your definition of "reasonable" is quite a bit looser than mine (given
that you consider calling a character device a block device
"reasonable").

Ok, I looked. Raw disk I/O is in RH7.0. That makes your links

There's a version of TeX (pdftex?) that creates pdf output
directly rather than going through dvi and ps intermediates.
I've never tried it. You can't use EPS figures w/ pdftex (which
I want to do), so I do exactly what you've described above.
You'll generally get much better PDF results if you use
standard PS fonts rather than the TeX default CM fonts:

Hi Vilmos,
if you depmod -a, will that cause any modules to be loaded.
How does depmod -a effect the running Linux system. What does
depmod actually do?
Thanks

From time to time, I do this: rpm -qa >rpms.txt
This makes a text file of every packagename installed.
another handy is rpm -qa |grep part of packagename
If you even get close, grep will give you the exact name that's in the
datatbase.
The verify process is working, also. All those "symbols" out at the left
have meaning as to the condition of the files. In the docs for rpm and
in it's man page they are explained.

I only use teTeX, but it might be the same with other TeX distributions:
Just type pdflatex file.tex and you're done. If you include the hyperref
package in your document ( \usepackage{hyperref} ) all references in
your document are clickable links, very cool.

When I issue the route command it has to think for quite some time
(minutes) before displaying the routing table. Also, pinging the local
ip address (not loopback) results in 70 to 80% packet loss. Pinging
this same ip from the network gets 0% loss. I've tried multiple
NIC's. Anybody have any ideas?

Probably nothing happens - kernel forks to init, init calls rc scripts,
etc.
Without these files, kernel only waits for I/O, I guess.

There are man pages for many, if not all. Also, I found a book called
"Linux Kernel Internals" (The author's names escape me, six people)
I highly recommend this book, the system calls are well documented in an
appendix, and the kernel code (data structures, algorithms), are all
described in fairly understandable terms.

A pentium ii 300 should not be running as slow as you are describing.
Logged in as root from the command prompt run:
xf86config
This will run you thru a script to reinstall your hardware for X. It sounds
to me like maybe your memory for your graphics card is not correct or
maybe your not using the right graphics driver. At the same time you
can fix your mouse problem by selecting a generic mouse driver instead
of the microsoft one.
Good Luck,
Jim

echo $PATH doesn't contain my current directory. Also, it doesn't
contain path, which I put. This is not only the problem of current
directory. I can't put any path into PATH environment variable. For
instance, I stalled JDK, so I put path (not CLASSPATH), but my system
doesn't recognize ~/jdk1.3/bin path.

My original question actually dealt with this circumstance:
In Gnome 1.2, at least in the themes & window managers I've seen in
Storm Linux, the only way to resize a window is using the right or
bottom edges of the window. But if a big window displays off the right
and bottom edges, how can I resize it? I can't get to the bottom
because I can't grab the title bar off of the top of the screen.
It turns out that my laptop can be configured so that it has a 3rd mouse
button. When I click that 3rd button, the middle one, on the window
title the mouse movement resizes the window.
Problem solved. Pity those without a 3rd mouse button.
Jerome.

Indeed.
It may very well be (*highly probable*) that separating the system
into some distinct components, some involving GUI, others _not_
involving GUI, will represent a Highly Effective Way of attacking the
problem.
If, for instance, there is a bunch of the analysis that Rightly
Requires having a compilable language to get good performance, you
might have part of the system be a "language environment" that lets
you compile programs that calculate things, reading from files, and
writing to other files.
Drawing charts of the results is a separate task; it _tends_ not to be
as computationally intensive; you might well want to use a scripting
language like Perl/Python to take the output files and transform them
into forms that might get pushed into existing charting tools like
Gnuplot
Note that there are organized links to a LOT of "scientific software"
at <http://sal.kachinatech.com/index.shtml>; "Scientific Applications
on Linux." This includes links to charting tools, and all sorts of
numerical analysis tools.
It is entirely possible that much of the desired functionality might
be readily assembled together by "scripting together" some of the
tools at SAL.
- For statistical analysis, you might start by writing a Python script
that pulls data from a database, or a web site, or [somewhere].
- Next step is to massage that somewhat, extracting the _critical_
bits, and reformatting them into a form amenable to analysis using
an existing ANOVA package.
- Next step is you get results from the ANOVA analysis. Perhaps to be
archived, with a Python script that pushes the bits that need to be
shown graphically into a form that may be parsed using Gnuplot.
Consider it stipulated that the suggestions above are made up out of
my head, and may need _substantial_ modification in order to comply
with the _true_ requirements. But consider the basic steps as generic
ones:
-> Data collection
-> Data analysis
-> Reporting
And at least _consider_ whether there may be existing tools that can
be "glued together" to satisfy the requirements.
