Reasons for a 3-tier achitecture for the WEB?
(NOTE: I said, WEB, NOT WINDOWS.
DON'T shoot your mouth off if you don't understand the difference.)
I hear only one reason and that's to switch a database from SQL Server to
Oracle or DB2 or vice versa... and that's it.... And a lot of these
enterprises don't need it as they already know what database they are going

Scenario:
This is a reporting scenario where it takes a while to get
back a response ( report page ) after submit.
I want my user to see some kind of temporary message like
'Processing...' or 'Waiting.. ' after I clicked on a SUBMIT

As you might expect, I execute the search in the background but I have to return to the UI thread to bind the results. While databinding, it appears as though the Timer.Tick event never gets fired, so my timer freezes at the time before...

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...

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