I have an issue with the title, as Delftse is a Dutch word. The adjective version of (the city) Delft. The title is thus an ugly combination of Dutch and English (Denglish). I think 'Delft Foundations of Computation' would be better.

It's a joke. A reference to "Delfts Blauw"

[timwaagh]

In Denglish, it is very ghostly.
