There is something with initializing mutable class attributes that I am
struggling with. I'll use an example to explain:
class Father:
attr1=None # this is OK
attr2= # this is wrong
def foo(self, data):
self.attr1=data
self.attr2.append(data)
The initialization of attr1 is obviously OK, all instances of Father
redefine it in the method foo. But the initialization of attr2 is wrong

Hi,
I have a series of Select menus on a page. I am trying to allow the user to
click on the Select title and have it popup a help window. This works fine
with the following code except that all the Select choices are lost.
<A
HREF="javascript:location='menu.jsp';window.open('menuhelp.jsp?menuID=5','me
nuhelp',)">MenuTitle</A>
I saw an example of a popup on a website that did not lose the menu choices.

Hello:
We are designing two multi-user client server applications that
performs large number of transactions on database servers. On an
average Application A has a 50% mix of select and update/insert/delete
statements and application B has 80-20 mix of select and
update/insert/delete statements. Being able to scale the databases as
needed so the performance is unaffected, is one of our critical
requirements. We've been investigating...

How hard (and desireable) would it be to give the user certain choices when
it comes to printing web pages?
The pages on my site use colours and pictures and contain an imbedded menu,
among other things. Now, I could make certain assumptions on the user's
behalf, such as making the background white and the text black, suppressing
the menu from the printed page, and even suppressing the printing of the
pictures if they are merely...

Hello everyone,
I am looking for a way to remove choices from cascading combo boxes as each selection is made.
Here's how this is laid out.
The initial combo box is STAGE and it will have choices STAGE1, STAGE2, STAGE3 and that will cascade to the CODE combo box. The CODE selections will also have lb. amounts for each code item. For example purposes here's the layout for the STAGE choices in the CODE combo box and use your imagination...

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

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,...
