Problem is that all these tests do is promote the idea that real-world
programming inside the matrix is about CS. Its not. Not knowing the answers to
the tests created by the OP does not make anyone a bad programmer. Hell, the
most productive programmer I know used to work with Visual Basic and
Excell/Access all day long. His code served thousands of users and he shipped

I do not see how a web developer or DBA will feel better about themselves and
more confident in what they do if they knew the answer to these questions. It
isnt even related to the work a Java EE architect does.

Since you say web developer... don't you think it's useful for web developers
to have some idea how much traffic is needed for A/B testing to produce
meaningful results?

Once you decide to do A/B-testing you only need to know enough about
probability to know that it is very hard to guess the amount of traffic
needed. That's
