I am writing an extension type, and wish to add some magic methods
which are not catered for by the tp_<whatever> slots (eg tp_init ->
__init__) in PyTypeObject. My methods seem to work correctly when
invoked explicitly (eg obj.__iadd__(3)) but the method seems not to be
associated with the corresponding operator (ie obj += 3 does NOT
work).
What am I likely to be doing wrong ?

Are MAGIC numbers always bad?
Using magic numbers (constant numbers) in programs are generally
considered a bad programming practice, and it's recommended that to
define constants in single, visible place in a header file. My question
is that is there any situation where using magic numbers is not
necessarily a bad thing? lets say that we want to initialize some
private variables in a class using some constant default numbers, can
we...

Just wondering if anyone knows how this component works.
If you set it up in the context of an Application.Run it works on it's
worker thread but it updates the progress on the UI thread.
My question is, how does it know which thread to use?
I used Reflector to track down the fact that it gets the delegates to call
via base.Events which derives from Component but how does it
know what to put into base.Events?
I'm very happy the...

Hi,
I recently started working a lot more in python than I have done in
the past. And I discovered something that totally removed the pretty
pink clouds of beautifulness that had surrounded my previous python
experiences: magic names (I felt almost as sad as when I discovered
the strange pink worms that eat you in nethack, not to mention the
mind flayers - I really hate them).
I guess all programming languages have magic names to some...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
