What would be the more proper way of storing birthday data? It will be
used to send out birthday messages for customers ("Happy 30th birthday,
Sam!"). But the date of birth is not necessarily known (in which case,
we will only send out "Happy birthday, Sam!").
I prefer using the builtin date type instead of three smallints. But I
don't like having to arbitrarily set, say, year 1000 AD or 1 BC to
represent "unknown year".
Any thoughts?

How about NULL?

Well if you make the column nullable, then you can detect that when
you retreive it.
Which column? If I use a single date column and set it nullable, I won't
be able to say "date of month and month is known, but year is unknown".
Anyway, I think I'll go with the single date column way.
You could also, if you don't want that, use a second
column to indicate that it's been set.

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,...
