How do you properly restart a Linux box? I use the command 'shutdown
-r now'. But, when I do that, while it is restarting, it tells me
that the volumes were not properly unmounted, and it does a scan of
them. How do I stop this in the future?
Thanks,
Jeff

Hi,
I'm using Midnight Commander 4.5.51. It has a mixed display of
directories and
files. I've been unsuccessful to configure it to display all directories
together and all files together, case-sensitive. How is it done?

If you put Linux on first, then load windows, win will overwrite the master
boot sector and prevent Linux from booting. Always better to install win
if you must ) and then install Linux.

Interesting question. I know that, back in the day, CompuServe sponsored
development of GIF viewers for a wide variety of computers, including low-
end 8-bit home systems like the Commodore 64, etc. Some of those systems
have even seen active development recently. You might look to those user
communities for what you need, though it will most likely be written in
assembly language rather than C.

Yes, the one in rc0.d says S01halt. And the one in rc6.d says
S01reboot. So, I am not sure what the problem is now. Is my halt
script in init.d bad?

No need for anything particularly special; DEFINITELY no need for a
"kernel driver" to make it work.
Steps:
-Plug it into the keyboard port on your PC.
-Plug keyboard into the socket on CueCat
-Head over to a virtual console or an xterm where nothing crucial
is happening...
-Swipe barcode off a book/magazine.
- Watch something like: .C3nZC3nZC3nZE3vWCxb7CNnY.fHmc.C3b1C3nZCxr0CNn3.
"magically" appear. (That's the UPC off a box of Kleenex.)
Up to this point, you have used NO software whatsoever.
My next "magical trick" is to take that barcode:
.C3nZC3nZC3nZE3vWCxb7CNnY.fHmc.C3b1C3nZCxr0CNn3.
and run it through "scat"
Basically, I select the line, and type (in vi):
!perl ~/bin/scat
which transforms the above to
000000000863238101 UPA 036000277104
The first part is the code value for the CueCat in question that
is the prefix for _EVERY_ scan; UPA indicates this is a UPC code
"type A", I believe; the last piece is the UPC code for the box
of Kleenex.
The "scat" source code:
#!/usr/bin/perl -n
printf "%s %s %s\n",
map {
tr /a-zA-Z0-9+-/ -_/;
$_=unpack 'u', chr(32+ length()*3/4) . $_;
s/\0+$//;
$_ ^= "C" x length;
} /\.([^.]+)/g;
See how the kernel never enters the picture?

We picked up a cuecat the other day at RS, but we can't get it working,
as I am still using an AT keyboard, and my wife's laptop has only one
PS2 slot designed for both the kb and the mouse.
But really, I am thankful. You give the CC folks your info, then you

I am not really interested in letting the world know everything about

Thanks for the info! I did not know a damn thing except what was in the
books about links until you guys taught me.
And the above command gave me just what I wanted....direct easy access.

Redhat 6.2 can handle it according to the install manual, but the deal
is WinLinux 2000 that is free on the current Maximum Linux CD.

I have gotten (Text file busy) this after I edit with vi a
perl script, the script will not execute, the only way
to get rid of this is to reboot.
Can anyone suggest a fix?

Hi,
I've done below 2 steps which solved my problem :
1. give option "auto" in /etc/fstab
2. do a symlink in /etc/rc2.d/rc3.d/S15netfs ti /etc/rc.d/init.d/netfs
lrwxrwxrwx 1 root root 22 Sep 23 09:05 S15netfs ->

thanks for the suggestions etc.

There have been a number of Unix variants that run on Z80: Cromix was
one, and I believe Zilog even offered a Unix clone for Z80 (during the
heyday of CP/M).

Well, you missed the Byte Magazine challange (about 1980 or so) to
develop a fax/scanner. IIRC, U of Waterloo (here in Ontario Canada)
came up with a photocell mounted on a movable, geared stand which was
attached to a phonograph player (y'a know, analog audio players <g>).
Mounted on the turntable was an applejuice can to which a document
would be attached, wrapped around the can. The turntable would spin
the document and the photocell would descend, scanning in helixal
lines around the document. A single bit A/D converter was used to
capture the data to a serial port on a computer where the scanned data
was built into a grayscale bitmap of the image.

If it were Black&White TV, then DOS stood for Disk Operating System,
and was written and sold by IBM for use on their S/360 mainframes. DOS
(IBM's mainframe OS) has grown up some, going to DOS/VS, then DOS/VSE,
then VSE/SP, then VSE/ESA. Tbat _other_ DOS is a "Johnny-come-lately"
with the advent of colour cable TV and programming in Pascal.

Why paint at all? As above, rust (iron oxide) is the stuff recording

Slackware uses standard kernels (no custom patches). I swear by it.

IIRC, The Linux Documentation Project (http://www.linuxdoc.org/) has
some docs on this. However, any Linux distribution that provides
support for install/boot from Win9x will also provide instructions.

Slackware Linux provides a couple of variants of this install
(ZipSlack is one). See http://www.slackware.com/ for the software and
instructions.
There are other distributions that also may be installed this way.
However, I don't have the details on them, so I'll leave it up to
their advocates to speak up.
