Application form for the 8-week Prolog course, as published on the official SWI-Prolog Twitter account.
When I was young, I was all about Prolog. I got a copy of Logic and Prolog by Richard Spencer-Smith and Stony Brook Prolog for the Amiga from Aminet and just went to town.
Now, sadly, there just isn’t much use for Prolog in what I do, and so I don’t use it anymore, and honestly never did professionally. It was, in a very true sense, a childhood summer romance that I occasionally try to recapture.
It’s completely unknown in the world of CRUD web apps, but I think it might be still used in niche areas.
SPARQL has similarities to prolog/datalog, but not exactly.
