I promised I'd put together a PEP for a 'generic object' data type for
Python 2.5 that allows one to replace __getitem__ style access with
dotted-attribute style access (without declaring another class). Any
comments would be appreciated!
Thanks!

What follows is a discussion of my experience with .NET generics & the
..NET framework (as implemented in the Visual Studio 2005 Beta 1),
which leads to questions as to why certain things are the way they
are.
***** Summary & Questions *****
In a nutshell, the current .NET generics & .NET framework make it
sometimes difficult or even impossible to write truly generic code.
For example, it seems to be impossible to write a truly generic

C++ template use constraint by signature,It's very flexible to programmer but
complex for complier, and at most time programmer can not
get clear error message from complier if error occur. C# generic use
constraint by type,complier is relaxed, but it is very limited to
programmer.Is there a way to get merits of both?
Maybe the following way can achieve this purpose :

I want to define a class that has a generic parameter that is itself a
generic class. For example, if I have a generic IQueue<Tinterface, and
class A wants to make use of a generic class that implements IQueue<Tfor
all types T (so it can make use of queues of various object types
internally). As useful as this is, it doesn't seem possible. The natural (but
illegal) notation would be something like
class A<QueueClasswhere QueueClass :...

I'm working on a system that has 4 different types of client they
have mostly the same attributes so I decided to create an interface
IClient for them to implement and then just add the differing
attributes as needed to each client class.
Now I get the Client information from a DB and Load them into a Generic
dictionary

Hello everyone,
I'm writing because I'm frustrated with the implementation of C#'s
generics, and need a workaround. I come from a Java background, and
am currently writing a portion of an application that needs
implementations in both Java and C#. I have the Java side done, and
it works fantastic, and the C# side is nearly there. The problem I'm
running into has to do with the differences in implementations of
Generics between the two...

I'm quite new to generics. I have 2 generic classes:
MyClass<Tand MyOtherClass<T>.
MyClass<Thas 2 public Add methods
Add(MyOtherClass<T>);
Add(MyOtherClass<Wrapper<T>>); (Wrapper<Tis another class that
contains an object of type T)
I have a third generic class: MyHandler<Twhich contains 2 Add
methods and a generic method:
Add(T obj)

Hi,
Is it possible for a generic list class to use Reflection on the
generic type being used to detect a property within that type that
refers to the same generic class, only with a different type as the
parameter?
From various posts and help, this is what I've got so far:
public class DataList<T: BindingList<T>

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....
Now, this would greatly impact the work of software developers. The idea...

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...
