Years ago I devoured books in the bookstore about a technology called "Cobra", a distributed object model in computer programming. I researched it heavily. Cobra, Cobra, Cobra.

One day I saw a computer book about "Corba", the same technology. I wondered how this book got to print with such a blatant typo.

So I looked at all the "Cobra" books I was already familiar with. They all now said "Corba".

I considered that maybe I was now in an alternate universe where everything was exactly the same, except for this Cobra/Corba anomaly.
