Ah... Netscape... with every click it writes to the cache, and it also
thrashes a lot as it maintains the cache.
So, not likely a memory or swap problem, just Netscape's messy cache
maintenance.

There is no "GUI-based source control system."
Source code is text, so the tools are text-based.
If you look, you may find GUI wrappers that can be put on top of CVS;
that will allow some portion of the administration to be done using
"graphical" tools.
Mind you, they're not usually particularly "graphical," any more than
file managers are ever particularly "graphical."

The X configuration should have come up near the end of the install. If
you set up X it also sets up GUI login (no choice). I set SuSE 7.1 up on
3 boxes, then later switched them to ASCII login (runlevel 3) with YaST or

I believe that install said to use SaX you did not set up X during

Incidentally, I noticed on the restore manpage that there's a "-s" option
which allows the selection of a "file number" on a stacked tape.
Assuming that dump didn't overwrite the first record, perhaps this would
permit you to locate the second archive.

Date: Sat, 07 Apr 2001 03:15:33 -0400
I am trying to switch from RedHat6.2 to SuSE7.1 and I've got most of my
stuff working. However, I cannot get the dial on demand stuff working
that I have set up on my RedHat 6.2 distro. Luckily I am working on
separate disks or I would be really screwd. Anyway, here is my basic set
up.
I use pppd for demand dialing and am using a chat-script to get
everything hooked up. All of this works on RH6.2 on mostly on SuSE. I've
copied my connect script and my ppp options file from RH6.2 to SuSE.
When I try to connect everything procedes normal until almost at the
end.
Here are the messages printed to /var/lo/messages.
For RedHat, this works:

If so, does anyone have a clue what the problem is? I did not compile

/dev/modem exists and is pointing to /dev/ttyS1 on both distributions.
Any help is appreciated.

I always wondered why RH advised users not to use up2date to upgrade
kernel packages... now I know...
This issue can be resolved in one of two ways:
1 ) manually reinstall the updated kernel packages yourself:
or
2) follow these steps...
cd /boot
ls -al
verify that the System.map-2.2.17, kernel.h-2.2.17,
module-info-2.2.17, and vmlinuz-2.2.17 are present and/or linked
properly from System.map, kernel.h, module-info, and vmlinuz
with ls -al you should see something like...
...
kernel.h --> kernel.h-2.2.17
module-info --> module-info-2.2.17
System.map --> System.map-2.2.17
vmlinuz --> vmlinuz-2.2.17
....
kernel.h-2.2.17
module-info-2.2.17
System.map-2.2.17
vmlinuz-2.2.17
....
if /boot looks okay, it's time to visit lilo.conf inside /etc.
cd /etc
use your favorite editor to verify the lilo.conf file, to make sure
that the "image=/boot/vmlinuz-2.2.17" is pointing to the right kernel.
in my case, that section looks like this:
....
"image=/boot/vmlinuz-2.4.3"
label=linux
read-only
root=/dev/hdc9
other=/dev/hda1
label=win98
Just remember that if you make any changes lilo.conf, to type lilo at
the prompt, so that it initializes it's pointers for the next reboot.

I obviously agree that for a lot of things there are better languages
than C++. For example, currently I'm working on a web project, and am
using PHP for it. I've made CGI applications in C++ before, and it's
really SO much easier in PHP. So you're right when you say that to get
things done in some fields there are other languages better suited.
As for strings and lists being inside a library instead of being inside
the language itself. This adds a downside and an upside. The downside is
that you've got to pay attention to what you do with your templates, but
the upside is that you only use what you really need. Although it's true
that in these days of gigabyte-sized operating systems making small
programs isn't really to the point anymore.

But you're not forced to use the extra stuff they put in, you can just
ignore it if you want to. You can use C++ as C with classes (like, for
example, the abiword project is doing).

I agree. There is a lot in there. But again, if you don't understand it,
or don't want to understand about it, ignore it.

I've only been programming in C++ for two years, but can you tell me
what it is that they added that you couldn't ignore ?

The original question was: is C++ complex ?
And my answer was: no, it's not. There is a difference between being
complex (an interwoven mass of spaghetti) and being large (C++). The way
to look at C++ is like in one of those "C++ in 24 hours" books. You
start from chapter one, and stop reading where you think it's getting
less useful. And you can just stop there. You don't need to know all of
it to use it right. Every feature can be used on it's own.
It's this whole idea of C++ being too complex that has made it so that
people don't even take a decent look at it. If more open source projects
would use the OO functionality in C++, instead of just sticking to basic
C, then not only development would be faster, but it would be easier for
new developers to join the ranks. C++ still can be C with OO features,
if you want it to.

James,

i.e have you t
tried using the command "top" when the machine is thrashing - it gives a list
