Hello all,
I am developing an interface system for an application I was written. This
interface will connect to other system to share information. I would like
to use
xml and xsl to generically describe each interface. The trouble I am having
is that it seem that if you export in xml by table then it is impossible to
combine the xml tables files back together in a hierarchical fashion. I can
do it programmatically but I would like to...

Hi,
Is it true that that "Python 3000" is dead ?
Honestly I think that e.g. changing 5/2 to be 2.5 (instead of 2) would
just break to much code :-(
On the otherhand I'm using Python as "Matlab replacement" and would
generally like 5/2 ==2.5
So, I was contemplating to default all my modules/scripts to start with
"from __future__ import division"
but if it is never coming (in this decade, that is) then it would be a

Does anyone know the logic behind why in VB.NET the result of a
floating-point division ('/') is -rounded- on being converted to an
integer type, such as with statements like
Dim x As Integer = 2/3 'after assignment, x is 1, whereas a sane person
would say it should be 0
Does Microsoft have a reason for this design decision? I understand
that this type of rounding can reduce the overall error in long
computation chains by reducing the...

For a long time,, There has been a discussion of trueFor division
versus integer division in Python.
I myslef prefer that / be used for integer division since almost
always, I want the result of the
division be truncated to integer.
However, today I reviewed the method to be used in Python to get true

Supposed unsigned int(32 bits) is the largest number that computer can
represent with a single variable.
Now, i have a big integer ( less than 64 bit, but great than 32 bit) .
i represent it by this way:
unsigned int dividend :
divident store low 32 bits of big integer, dividend store high 32
bits of big integer.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
