I'm trying to reinstall RedHat 7.1 Linux on a PC that was disabled when
I tried to upgrade from RH7.1 to RH9. This is presenting lots of unexpected
difficulties. Apart from wanting to keep the old model T in shape, I'm treating
this as a learning experience. Right now, I'm trying to gain more control
over the installation CD. By that I mean, I intend to modify the installation
script and other aspects of the CD and burn a new installation...

I looked around for a way to change the format and the decimal setting
of a REAL type variable, but I can't seem to be able to find the
synthax anywhere.
Here is an exemple of what I am doing:
ALTER TABLE MAIN ALTER COLUMN sup_visee REAL;
It works, it changes the column "sup_visee" which was a String into a
REAL. What I want to do too is to be able to set the REAL format to

Hi,
I have to write a setuid program which is going to check for
accesslogs based on the real user who had invoked the executable.
I need to get the real and effective user-ids of the system
and based on the real user-id i need to filter logs only for that
user and give it for further activity. My idea was to get the real
userid, groupid and search for a pattern x:userid:groupid in the
/etc/password file. But again that involves fork,...

Hallo,
It is know issue that due to the fact that computer has to store the real
numbers in limited set of bytes, thus causing a minor imprecision from the
decimal value that likely was stored. I don't know, how dotnet framework
stored doubles, but it's certain, that if I store, say, 1.234567 in some
real variable, it is stored in memory like something close to
1.2345670000000000000003454786544 or...

Hi, now that in .NET everything is on millimeter, I was wondering how
can one convert Pixel to Millimeter and any user's screen/monitor. I
saw the following code on how to convert pixel to millimeter. It's
done on pascal/delphi, but can be very easily read & converted to VB
..NET.
However my question is what is the difference between "real"
millimeters and "logical" millimeters?
The source of the code is in the following thread:

Howdy,
I want to write an application, with some functionality that will
detect my "Real World" ip address, ie that of my router, as opposed to
the actual IP it is running on which is a 192.168.1.x address.
So the .NET app needs to some how find out what real world IP address
it is running on.
There are web pages (such as www.mywanip.com) that can tell me, and I
suppose I could write my application to connect to that page, and parse

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
