You might try looking at /proc/partitions, and the source for
same.

Theoretically it should be possible. But there has to be an
implementation that only looks at the MAC of your network card for
adressing. Maybe it is necessary to develop your own networking
software. Practically every networking software is build according the
OSI model. That is too much overhead for your needs. TCP/IP is certainly
not capable of routing the data as you want it. If it makes any sense to
go this way...?
Maybe there are some specialists with more knowledge about networking,
that can give you a more specific answer. I am just a student...:)
Good Luck!

I'm not a real fan of man pages. But are an essential tool. I think I
will take a man page and a seperate book(with examples) over windows
help files that are bigger than the actual application.
Go buy a book that has examples in it and use the man pages as a
reference. I think that's all they are intended for.

Subject: trying to write a module which uses parallel port, but inb( port ) is
Date: Fri, 29 Jan 1999 20:01:55 +0100
I got my hands on a module which is supposed to create a link to your
texas-calculator using the parallel port. It didn't work, so I sat down
and went searching in the code. I'm not at all experienced in kernel
programming, but I tracked it down to this: inb( port ) always returned
74. It doesnt matter what was written in the other end or what is
written from the computer, the return value from inb is always 74. I
know that the hardware is correct, because it works under dos, and the
shematic for the cable is very easy to check with an ohm-meter. I
haven't any support for lp in the kernel, so that shouldn't affect. What
can be the problem? The code is about 1.5 years old, does that old code
work with recent( 2.0.36 ) kernels? I've heard the reverse.
Besides, is there a good way to print out variables from the kernel?
Like you can in a normal program with printf
Grateful for help

ls -F or ls -s may also be good comparisons.

Subject: how to find size of block device like /dev/hda
Hello,
I'd like to access a hard disk as directly as possible for benchmarking
purposes. So far I have come up with the idea of using the raw device
file, e.h. /dev/hda. How do I find out the size of the corresponding
disk? A simple call of stat() on the device returns a size of zero :-(
Thanks

Linux people are all users of linux.
What you think about them is largely irrelevant.
If you want linux improved, improve it. There is nothing
to keep anyone from making any changes they want and
distributing them as widely as they wish. That is the
strength of the GPL operating system. No one owns it. You
don't have any marketing engineer to talk to about what
options you want. If you want something done - do it.
That includes re-writing man pages.
Or merely changing them and emailing a diff to the
maintainer.

The overall effects are fairly interesting, due to the separation of
responsibilities.
VISA and MasterCard get their 1.5% "pound of flesh" out of retailers;
they leave (or so it certainly appears) the profits from interest to the
banks that issue the cards.
If the bank doesn't get a penny except on interest charges, then a "big
spender" that doesn't carry a balance may be VISA's "best friend," the
fact that the bank has to capitalize the "grace period" makes them hate
that big spender.
This makes the push for "debit cards" and "VISA Check Cards" make a
whole lot more sense. VISA doesn't care; banks do...

Actually, examples might be something better suited
to printed media regardless of whether or not you
bought it or dumped it from a pdf file from the redhat
CD. This tends to be the case for me with some of the
better HOWTOs. They are essentially highly detailed
examples.

A far more common scenario is one in which the customer makes a deal
with the transport agent, who then refuses to deliver goods to any
market except that of the customer. The farmer, faced with selling to
said customer or losing his goods altogether, then "makes a deal."

A shame your expertise does not match your presumption. The 19th
Century and early 20th Century were just a long cycle of economic
growth, recession and depression. I don't know to what "runs on
banks" you are referring, or why, since the major economic problems of
recessions are not associated with these.

There's no such body of evidence. All the evidence is that
cooperative projects are far more effective in reaching goals than
tooth-and-claw competition. Certainly, cooperation is more effective
than the monopolistic capitalism which you unthinkingly worship.

Replace "alternative" with "slow". I've done streams programming and I
