Can you give some examples? Most things I'm aware of that could be classified as puzzles require, at the very least, enormous time investment, if not specialization, and there's often lots of drudgery along the way.

Sure.

How can I get the D programming language to generate even faster code?

How can I take this piece of existing, working, kludgy code, and make it simple and elegant?

How do I distill the advantages of D into an elevator pitch?

What is the right combination of aftermarket parts that will make the engine in my Dodge deliver the characteristics I want?

How do I salvage a relationship with a valued colleague that has gone awry?

How do I optimize my investments to maximize returns?

I could go on forever.
