I have written the following code, to test the concept of storing
objects in a vector. I encounter two run time errors:
1). myClass gets destructed when pushed onto the vector
2). Prog throws a "SEGV" when run (presumably - attempt to delete
deleted memory.
Please take a look and see if you can notice any mistakes I'm making.
Basically, I want to store classes of my objects in a vector. I also
have three further questions:

I know this is the wrong way to do it, but maybe someone can tell me the
right way to do it...
I have two different databases that I need to synchronize. The database
doesn't have keys exactly, but it does provide a rowid function.
So, I am storing a dictionary of <string, long>, string being the rowid
and long being a sum of the hash code for each column in the row.
With this dictionary, it is very easy to determine if a row is...

Hi,
I'm new to Python and working on a school assignment.
I have setup a dictionary where the keys point to an object. Each
object has two member variables. I need to find the smallest value
contained in this group of objects.
The objects are defined as follows:

Hello everyone,
I'm storing functions in a dictionary (this is basically for cooking up
my own fancy schmancy callback scheme, mainly for learning purpose):

As was pointed out already, this is a basic misunderstanding of
assignment, which is common with people learning Python.
To your actual problem... Why do you wanna do this anyway? If you want
to change the function in the dictionary, why don't you simply define
the functions you'll want to use, and change the one you have bound to
the key in the dictionary when you want to...

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...

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...
