The Internet of Things: A New World Order?

Was the marketing hook 'The Internet of Things' conjured up before the technical definition? Are we being persuaded to spend money on fending off yet another fantasy tsunami of data? Already, we have televisions that listen to, and report, your conversations; so are we facing the Science Fiction future of gadgets that report where you go, who you visit and what medications you take? As Robert Sheldon says; "It's big, almost too big to get your arms around".

Question of the Day

Finding Trailing Spaces

I have some data in a SQL Server 2025 database. It looks like this for the dbo.Customer table: 

CustomerID CustomerName PreferredName
1          Steve        Steve               
2          Andy         Andy               
3          Brian        Brian               
4          Allan        Allan               
5          Devin        Devin               
6          Steve        Steve               
7          Sally        Sally
I want to detect which names have a single trailing space. The CustomerName is a varchar() and the PreferredName is a CHAR(). Does this query detect the problem rows? 
SELECT 
       CustomerID,
       CustomerName,
       PreferredName
FROM Customer
WHERE CustomerName <> RTRIM(CustomerName)
OR PreferredName <> RTRIM(PreferredName);
