Would someone please list for me the files to be changed for kernel
driver modules to be installed at boot time rather than later with an
insmod command. Or better yet point me to where this procedure is
documented.
Thanks for the help.

The smallest web serving system that I have seen is QNX's demo: the
whole OS, PPP dialer, browser, and server fits on _one_ 1.44MB floppy,
and boots and runs in very little RAM. You can run a server that
displays the analog of "/bin/ps" on a dynamic HTML page.

I would suggest that every arrangement *does* exist because of or for
some form of economic benefit.
Note that I didn't say *monetary* benefit...
People build free software because they think it provides *some* sort of
benefit outweighing the costs of producing it. That's economic
benefit...

That's just funny!
I looked at their prices etc. Let's see, I can pay thousands of dollars
to run my linux apps on flaky NT,
or I can just BUY a second PC (with all options), and run my Linux apps
on stable Linux for the same or less money...hmm, real tough choice

Except of course that Xt DOES pass "self" as the first arguement to the
callbacks. Under Xt, callbacks take three pointers. The first is a pointer to
the widget that called this callback. In your example, the button. (From
there, you can get the rest of them.) The second argument is a pointer to your
data, whatever that might be. The third argument is a pointer to data specific
to the type of callback. Motif uses the third one extensively to pass GUI
state info to the callback.

Subject: Advice: NT Service vs. Linux Daemon??? Which is easier?
Date: Tue, 2 Feb 1999 20:59:51 -0500
Hi:
Advice, opinions, etc., please! I'm looking for feedback on which would be
easier to program.
I'm very interested in learning to develop server-side applications in C
and/or C++ (such as
a web-server, for instance. I realize that the source for Apache is freely
available, but I think that's probably a little difficult for me to start
mucking around with.). My C/C++ knowledge is limited, but I am
studying it and experimenting with it of knowledge. Given what I'd like to
focus
on, what are opinions on the easiest platform to start with (specifically,
for socket-type daemons)? In other
words, which is easier to write (with an http server as an example): a
Linux
daemon or an NT service. My current knowledge of the MS WinNT platform is
somewhat better than my unix/Linux knowledge.
Does anyone have any words of wisdom? Doubly thankful if you would email as
well as posting.
Btw, does anyone write anything is just plain C anymore, or is everything
pretty much done with C++?

But there is a very big difference in "Reality" between an X server
and "Unix emulator". With just an X server, you still need to own and
operate a machine running Unix to run Unix apps. If you had a Unix
emulator, presumably that means you could get Unix apps and just run
them on your NT machine. The sysadmin may be able to write some kewl
scripts so that an end-user on the NT machine doesn't realize they're
starting an X app, but that still only accounts for GUI Unix apps; to
start a non-gui Unix app you'd still need to actually log into the
Unix machine, whereas if you had a Unix emulator you could just run
them on your NT machine too.

Are you booting from floppy and "rdev"-ing the kernel? I used to
religiously recite the following incantation:
# cp /vmlinuz /dev/fd0
# rdev -R /dev/fd0 1
# rdev /dev/fd0 /dev/sda7
upon my 2.0.xx kernels, if only out of habit. However, this little
maneuver, when applied to a 2.[12].xxx kernel, prevents it from even
booting. Just copying the kernel to floppy is good enough,
apparently.

I suggest a book by WROX PRESS called "Beginning Linux Programming"
It is centered around writing programs for Linux for the user who is not
familiar with UNIX. It takes you through understading command shells
and your ENVIRONMENT, to writing shell programs and understanding
standard in and standard out.
Then it will walk you through writing a Character Mode Interface with menus
for a CD music library database in bash.
Then it will teach you a little about C programming and you will rewrite
the
same program in C.
Then you learn about the Web and how to write CGI programs. again you
write the program with a web interface.
Then you learn about X-windows and how to program in GUI mode.
You will learn a lot about UNIX in general and programming in general
by working through this book.
It is so well written that I have had to buy 4 copies of it because every
time
I lend it to someone like yourself they return it so dog-earred and
broken-backed
that I tell them to keep it as a present.
It is BRIGHT RED with YELLOW LETTERING.

Subject: 2.2.1 Mysterious crashes
Date: Wed, 03 Feb 1999 21:16:54 GMT
I have been running 2.2.1 on a dec multia for a week or so. It seems
to crash regularly with NO info as to what happened. I end up back in
the srm boot prompt and even that latches up so i have to power cycle
the machine.
Is there any particular thing I can do to try to have some state data
available to track down the problem? Generally it occurs during a
compile of egcs or other large package.
I do not see any way of enabling any extra debugging methodology or
logging. All I see is a dead period in /var/log/messages from when
the machine stopped dead to when I power cycled it. One time I found
the machine with a page of data which I had no hope of copying down
but that is once in 20 crashes or so.

I believe you can achieve the same thing with less effort:
Just write the code you need as regular demons, and run them at low
