We all know that using __getattr__() we can compute an instance
variable on demand, for example:
class Foo:
def __getattr__ (self, name):
if name == 'bar':
self.bar = 'apple'
return self.bar
else:
raise AttributeError()

Hi I'm developing a program and the client is worried about future
reuse of the code. Say 5, 10, 15 years down the road. This will be a
major factor in selecting the development language. Any comments on
past experience, research articles, comments on the matter would be
much appreciated. I suspect something like C would be the best based
on comments I received from the VB news group.
Thanks for the help in advance

I have a base class in an assembly that I want to add the following
attribute:
The assembly is strong named and all the derived classes are in the same
assembly. The problem that arises is that at runtime it fails to
de-serialize a derived instance of the base object, it complains about a
property of the base class cannot be serialised because it is decorated with
declarative security permission attrbiutes.

Hi
We have windows application and have created our own custom principle &
identity objects that implement IPrinciple and IIdentity. When a user logs
into our system we set the threads principle to our custom principle object
by calling Thread.CurrentPrinciple = blah. This all works great for role
based security. BUT lets say i want to run one line of code which causes an
imperative security demand:
Dns.GetHostName();

Hello All,
I have couple of doubts regarding the concept of on-demand javascript
loading using javascript code. I could see on the net different
techniques for achieving this - techniques like:
1. document.write("<script src=
language='JavaScript'></script>);
2. sc = document.createElement("<script>"); sc.setAttribute("src",
); and append this to the head

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

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
