Hello again,
I have a dictionary with the following content :
'LZ': {'type': 'N', 'bytes': '00008'},
'LVI000': {'type': 'N', 'bytes': '000010'}
This could be seen as a interface description to deal with an external
program that needs a 18 Byte communication area. 8 and 18 Bytes have
to be interpreted as a "Number" String representation. eg like

My problem is about properties and the virtuality of the methods. I
would like to create a property whose get and set methods
are virtual. I had the same problems in Delphi before and the solution
was the same. I created a private _get method and a public
get method. The former one will call the latter. The same stands for
_set and set. Here is an example below:

def namechanged(self):

I'd like to discuss about the opportunity to have a global objects
creator that introduces into a general framework
(suited for multithreading) a controlled semantic to manage
globals variables (objects and scalar-types).
In the following example Global is able to create objects of any kind
with and index value attached to. So a Global<0, string> is a unique
string instance object allocated into the system that can be accessed
from any...

Hi there,
I am writing a smart pointer that is similar to the boost intrusive ptr.
I am trying to make it behave like a c++ pointer including the implicit
and explicit casting behaviour.
Below is the part more or less relevant to my problem.
Version 1 is fine for casting to a derived class, but it must be called
explicitly even though it is used to cast to a base class.

I understand how to create a property like this:
class RC(object):
def _set_pwm(self, v):
self._pwm01 = v % 256
def _get_pwm(self):
return self._pwm01
pwm01 = property(_get_pwm, _set_pwm)

hello, I wrote this but it doens't compile; more or less I see the error; I have to include "pattern.h" instead of "class Pattern" in patternset.h; But I don't understand why:
This is the error:
error C2027: use of undefined type 'Pattern'
see declaration of 'Pattern'
error C2227: left of '->getValues' must point to class/struct/union/generic type
and this the code:

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:

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.

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...
