I think I know the answer to this, but suggestions welcomed.
I have to store lots of information. An electricity reading every half
hour for hundreds of meters for several years.
The ways I thought of storing this in SQL were:
1. One table row per day with 48 fields for the readings.
144M table, 3M index
saves space and having a long skinny table
however, getting the min/max reading in a day is a pain. I

Oracle 9i provides a "USING" clause option for inner joins, that
allows me to say:
SELECT * FROM TBL1 JOIN TBL2 USING KeyColumn
assuming KeyColumn is in both TBL1 and TBL2. This is HIGHLY desirable
for our software make use of, but we also support SQL Server. There
is no USING option available, and

I'm very new to using C# in an ASP.NET application, and am used to
using the ADO GetRows() method to quickly dump data into a
multidimensional array in classic ASP.
I am trying to work through using the ArrayList class in ASP.NET to
perform a similar role, but am having difficulty in understanding and
knowing how to access the data once it has been placed in an
ArrayList.

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...

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,...
