So, Wolfram Alpha does jokes too.

Confession:

I rely on WolframAlpha to simplify Boolean logic a little too much.

Wow, I still remember some math after decades. Today, I needed some parameter calculation in an interval with smooth transition at both ends (i.e. continuously differentiable). So I used a 3rd degree polynomial where the values and derivations gave a 4x4 linear equation system. I lazily hacked that into WolframAlpha, and it works nicely.
