I am not sure about it. It is true that sometimes I just can not open
a second xterm with trsh to my internet provider. I guess that might

I have linux running on a P5.  Its great!  To my knowledge, we are all waiting

My machine is plenty fast.  For heavy duty X windows work and graphics, like

Hopefully, 64MB will cure the slow reading of ppm files.

I think that I've probably got at least 10 compilers or interpreters
on my OS/2 system.  Let's see: C Set++, Borland C++, gcc, perl, REXX,
GNU Emacs lisp, CA Realizer (both the Windows and the OS/2 versions),
qbasic, gwbasic, f2c,...  There are probably one or two more that I've
forgotten about, for that matter.  And yes, I've used all of them at
one time or another.  And, of course, TeX is Turing complete, so you
could think of that as yet another interpreter if you really want to.

Dear Linux experts,
I would appreciate a lot if you could give me recommendations on laptop computers

"Linux is reported to run on 386/486 laptops, with X on most of them."
However, that's the only information I have now.  I know it's better to have
at least 8MB and > 100MB.

This isn't a particularly pressing question, but I was rather curious...
I've seen from a couple of sources that Linux has the ability to use all
"free" memory as drive cache.  What I wanted to know is: Is this a read
cache, or both a read-write cache?  (stage write, or write through?)

Also, is this a feature of Unix's in general?

Recently I found a nice use for kill -9. I have been working on SCSI
drivers and one section of the code is littered with debug output using
printk. When using the driver, all this output goes to klogd and gets
written to /var/adm/{kernel,messages}. This means a HUGE slowdown since
it's switching between writing to SCSI and IDE and who knows what else is
going on but it is bad. So, I 'kill'ed klogd and syslogd and all the debug
output started appearing all over my console. Great. That's what I wanted
to see but after a while (and many recompilations and reboots) I wanted to
run it without debug info turning up on my screen to gauge the performance
of the driver. Solution? kill -9 syslogd and klogd. This nukes the
processes but they get no oppurtunity to relinquish their hold on the
message stream. Result: messages disappear into nowhere with no performance
hit for disk writes and no mess on my screen. Far easier than a recompile
(which was not an option since I needed the debug code in there for other
purposes) or changing my syslog setup which is a pain.

But agreed, kill -9 is only for emergencies otherwise.

Ack!  I'm behind on my acronyms.  What is ODI?

The spec for Netware 3.x device drivers is pretty good.  I had no real
trouble using it to implement a complete SCSI CAM system with drivers
for all the NCR host adaptors.

*Developing* Netware drivers without Novell's support would be hard,
becuase you need Novell's NLMLINK linker to link them.  However, what
I am suggesting for Linux is merely *using* already developed Novell
drivers.  All that would require (begin hand waving) is implementing
the interface described in the spec.

For the most part, that interface is very clean.  I can't tell what
other drivers do, but thinking about my CAM drivers for NCR cards, it
would take a kernel hacker about a day to modify a generic Unix system
to support them (after the format of the driver file is figured out
so that the things could be loaded--I have no idea how hard that would
be).  If Linux inside is at all like Unix systems I've looked at, it
should take a similar amount of work.  I don't recall offhand anything
in the Netware driver interface that I didn't use in the NCR drivers
that would be difficult, so I think such support would probably end
up enabling most Netware mass storage drivers, not just the ones
I'm familiar with.

Reply-To: Ian@netrider.demon.co.uk
Date: Wed, 6 Jul 1994 05:09:32 +0000

I recently posted a plea for help regarding X screen refresh 
problems with a Fahrenheit 1280 card (random areas of the screen
not refreshing after exposure events, text characters and cursor
becoming corrupted).  I tried an old S3 driver program which
exhibited the same effects, but then spotted a bugs report that
came with the driver.  The report said that there could be
problems with conflicts with serial port COM4.  As it happens, I'd
recently added a serial card to the system and configured COM4....

....soooo, I thought, nah, it can't be that, but I'll take the
card out anyway and see what happens.

Et voila!  The X refresh problem went away!  Re-inserted the serial
card, configured now for COM2 instead of COM4, and everything
works perfectly.

I've no idea why there should be an interaction with the COM4 port,
but the bug report was right.

So, if anyone out there maintains an FAQ on Fahrenheit cards, you
may care to add the following:

_____________________________________________________________________

Fahrenheit 1280 S3 adapter conflict with COM4.
==============================================
Problems of screen refresh under X-windows have been experienced
with this card where the system also contains a configured COM4 port
(base address 2e8, IRQ 3).  Symptoms include random areas of the
display not refreshing after exposure events, text characters
disappearing at random and/or changing to black rectangles, X
cursor changing to a set of short vertical bars.

Workaround is to reconfigure the com port to something other than
COM4.
