Same. User Mode Linux was my guess; the first paragragh of the article was enought to tell me that was wrong but gave no hint of what the acronym might mean, not even broadly. I had to google : it is actually about Unified Modeling Language diagrams of object classes and their relationships. I guess nobody who uses UML diagrams ever thinks of UML as an acronym?
