That has got to be the best name for a website that I've seen in a long, long, time! I like the idea of a daily WTF...

Perhaps out of a general sense of respect for ones elders, I have a more charitable attitude towards Mumps than does the author of the article you reference. I do not dispute the various uglynesses he describes, but I believe that they were much less relevant when the language was created, back when the main consideration was shoehorning code into very tiny amounts of memory.

The place where I'm at now extensively uses the GT.M implementation of Mumps (FIS, they own it), and they tell me it's rock-solid and blindingly fast, they have to wait for Oracle to catch up to it when interfacing with customers who use Oracle. I don't really understand it, but apparently they don't write big programs in the Mumps language, they write DB interfaces that they call with Java.
