I need a couple things:
1. Word Processor label templates for common Avery/Xerox mailing labels
(Avery 5664 in particular). Ant the ability to simply type in the label
text manually, not needing to do some complicated process of creating a
database before I can get the labels. Also, the word processor must
allow graphic objects to be pasted in from the drawing program.
I know Applix can do this except it doesn't have the preformatted
labels. I would have to set up my own frames by hand I think, in the
older Applix 4.3 which I have. If it has label functionality, it is
nowhere obvious.
2. The drawing program should have good precision drawing features. SO
is better than Applix 4.3 in this regard, because SO shows cursors in
the vertical and horizontal rulers that correspond to the edges of the
bounding box for the object being moved. It also shows the exact
coordinates of the upper left corner, and the dimensions of the object
itself. Whereas in Applix 4.3, when you move an object in the Draw
program, the rulers show a cursor that is the mouse coordinates. That
is not very useful for precision positioning because the mouse
coordinates are arbitrary relative to the object being moved. You can
try to carefully position the mouse before moving, but that is kludgy
and there are little burps that always disturb the precision of this
method anyway.
Star Office has very good precision drawing features.
Applixware 5.0 is cheap enough that I may try it.

Yes, the Open Office sounds like a good direction for Star Office.
Perhaps it can solve some stability problems as well by being developed
closer to modern Linux libs.

Subject: How do I update RH 7.1 correctly using RPMs?
Date: Thu, 17 May 2001 14:26:17 -0400
I have a basic question about keeping my RH 7.1 Linux box up-to-date. I see
that there are already several patches and upgrades of various sorts
available in the form of RPMs off Redhat's website, which I have downloaded.
Now what? For instance, if I do an "rpm -Uvh
netscape-common-4.77-1.i386.rpm", I get several warning messages about other
programs (such as Netscape Navigator and KDE) which are dependent on the
netscape-common-4.76 files. Should I ignore these warning, and issue a
"rpm -e -nodeps" for the old netscape-common-4.76 package, then install the
new package? Or will this break some program or tool that needed the old
package and doesn't know what to do with the new package?
Another example:
> rpm -Uvh arts-2.1.2-1.i386.rpm
error: failed dependencies:
arts = 2.1.1 is needed by kdelibs-sound-2.1.1-5
If I force the removal of the old 2.1.1 package, then install 2.1.2, will
kdelibs-sound be OK with that? Or will it still be looking for arts 2.1.1
(and therefore break).
That's just a couple of examples, but I guess what I'm looking for is a more
general answer - what's the normal procedure for keeping a Linux box
up-to-date? Is it the same set of commands that I just issue each time I
download an updated RPM? And can I automate the process (through autorpm or
some such tool)?
Thanks to anyone who can help me get started.

No, not never. But so few times that I can not recall when and how often.
In fact, I do not remember the last time it crashed at all.
The documents were not always very complex. The worst were several tens of
pages (40 max.) with embedded objects such as graphics (vector and
bitmap), and tables. Some material was SO native (e.g. Calc) some foreign
(e.g. Visio).

I've used SO 5.1 & 5.2 on SuSE 5.2, 6.0, & 6.4. Mind you - I've cutomized
my distros to hell. My SuSE 6.4 is acutally a Linux 2.4.4. So when you ask
me for distro details, my "I've got SuSE 6.4" does not mean much. My gcc,
cardmgr, ppp, and lot's of others have been upgraded to the newest.

Hello,
If you have all the updated RPMS in the same directory just use:
rpm -Fvh *.rpm
The "F" means "freshen". This will install the updates only for the RPMS
you already have installed.
Look at the manpage for rpm too see all the options it uses.

There is a difference between being "used" and being "used". Although the
RAM is in use, it is not reserved. It will get thrown out by the kernel
automatically when it needs more memory. You don't need to do that.
Most of what is in the swap in your case is cached data - the kernel will
start removing the "old" cached material when you load some thing else
that needs a lot of memory, and create a new cache.
If you have a default install of Red Hat (RH), that you would probably be
better off if you tried to figure out what server deamons are running that
you don't need. The processes are active, although unnecessary, and
consume memory that can not be released.
So, if you never print, why run the printer daemon (lpd). If you never use
IRC, get rid of ident. etc.
Does anybody happen to know where the kernel memory management algorythms
are discussed? I don't fancy reading the source, but I love to read a
discussion thereof.

I've heard DiaLogic are working on providing drivers for Linux - which is
beside the point form your stance I guess.
But, unless you use one of these, how do think you can "read" from the
Plain Old Telephone System (POTS)? The only other option is through the
sound card. So, maybe, look in the direction of Voice Over IP (VOIP).
There has been some work done on supporting VOIP in the Linux kernel. Even
full H.323 (is that right?). The old way used to be that you did in fact
use you sound card and somehow magically connected to POTS. But thesedays,
I think they're going back to having a special VIOP device.
So, if you really want to make do with existing hardware, take a look are
VOIP the-old-way.
Oh, and in terms of your spec - I think you'll be fine with Pentium and
16MB. I remember from meeting some folks who did Call Center stuff, who
used low level Pentium boxes with DiaLogics build wanna-be PBXs. I think,
you'll get away with high end 486s if you do DiaLogic. Otherwise the CPU
has to do all the processing (i.e. POTS ADC).
Just some thoughts. Hope they help.

Leif

FWIW...
If you spend as much time with Mac as you have with the other OSs
I believe you would have a much better perspective.
None of the OSs are perfect. Each has its own strengths and weaknesses.
I tend to favor the old Mac for graphical work as that has been its main
strength from day one. And it rarely disappoints...
Maybe Linux one day but its still a WIP. Very stable but limited...

I think "make bzdisk" should work. Or you've already built the
(compressed, bootable) kernel, you can just do
"cp COMPRESSED_KERNEL_IMAGE /dev/fd0", where
COMPRESSED_KERNEL_IMAGE is /PATH/TO/KERNEL/SOURCE/arch/i386/boot/zImage
or ..../bzImage, as appropriate.

You should do this for security purposes, not really for memory-consumption
reasons.

Unused daemons are not particularly active. Most of their pages will
eventually be swapped out, so they should consume very little RAM.
One exeception is (x)ntpd, which is locked into RAM because it is
time-critical. (As long as you can reach your time servers, it is not
inactive, though.)

It depends on how you modified the 2.2.18 source code. If you merely
deleted files, you can tell patch(1) to skip patches that it doesn't know
how to apply (because the changed files are gone). It will chat at you
and you will have to respond to it.

You are not _required_ to have System.map files in /boot. I don't see any
mentions of System.map in FHS 2.1 or 2.2-beta. FHS 2.1 says
: 3.2 /boot : Static files of the boot loader
:
: This directory contains everything required for the boot process except
: configuration files and the map installer. Thus /boot stores data that is

System.map files are not used to boot, and are not used by the kernel.

Probably it should point to System.map-$(uname -r), since the latest kernel
isn't always the one that's running.
> Some older software scanned System.map directly (as opposed to

Programs like ps(1) and klogd(8) look for System.map in /boot, but these
are willing to look elsewhere as well. (See their man pages. The klogd(8)
man page doesn't say that it looks at /boot/System.map-$(uname -r), but the
changelog.Debian file suggests that it does.)
