Hello,
I thought about a new Python feature. Please tell me what you think
about it.
Say you want to write a base class with some unimplemented methods, that
subclasses must implement (or maybe even just declare an interface, with
no methods implemented). Right now, you don't really have a way to do
it. You can leave the methods with a "pass", or raise a
NotImplementedError, but even in the best solution that I know of,

I am writing a python program which needs to support some plug-ins. I
have an XML file storing some dynamic structures. XML file records some
class names whose instance needs to be created in the run time while
parsing the XML file. I wonder what is the best solution for this
problem?
I also have some problem about the "import". How should I design my
packages?
Say, I have all code locates at c:\projects\sami, "c:\project" is in my...

Hi.
Sorry for the probable dumbness of my question, but the behaviour I'm
observing seems a blatant defect in the C++ Standard or in the
implementation I'm using (several different versions of GCC, all
behaving exactly the same, GNU binutils, GNU/Linux on PowerPC).
Let's say I have two compilation units, a.cc and b.cc; each of them

matters) which I want to be transparent,...

"-ERR Logon Failure" from the server.
My code is very simple and just...

What might be a relatively useful or effective way to explain what a
"Framework" is to non technical business managers. My situation is that I've
been presenting the .NET Framework to these sorts of people in terms of the
things it includes (a runtime environment, application development
environment complete with multiple languages, an IDE - yes I know some
people say it's not really part of the .NET Framework, per se). While it's
how I've...

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,...
