i am having trouble updating a datset because i get the follwing error
in the Data Adapter configuration Wizard:
Generated UPDATE statement. could not determine which columns uniquely
identify the rows for "Customers"
'Customers' is the only table from the database that im using for this
query, so it cant be anything to do with a problem of having multiple
tables. and the primary key is set. so i dont understand what the
problem is.

Hi,
If I want to uniquely identify a computer. I can read CPU ID or Mac Address.
I heard, but is this true: some BIOS can block CPU ID from being read? (In
this case, will I get an exception, null or empty string for method
managementObject.Properties?)
So maybe Mac address is better way. But when I read Mac address for my
laptop, I got:

A quick sanity check, and I think I am correct, but just to make
sure: if you have a bunch of objects that are very much like one
another you can uniquely track them simply by using an ArrayList or
Array, correct? An example: create the object, create an array, the
stuff the object into the array. Later on, assume the object is
mutable, the object changes, but you can find it, if you have enough
state information to uniquely identify...

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,...

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...
