      UML used to refer to an entity/relationship+methods modeling language. https://en.wikipedia.org/wiki/Unified_Modeling_Language https://en.wikipedia.org/wiki/Unified_Modeling_Language

        Thank goodness we hear almost nothing about UML any more.

          Why the hate for UML diagrams. They are quite useful.

          Just last week someone on our project was drawing a sequence diagram for an interaction between lambda calls on a cloud provider. UML is pretty much in use on the enterprise space.

  It's the other direction. UML runs Linux kernel in ring 3. It emulates hardware protection mechanisms in order to make debugging easier and to run VMs when there is no kernel access. UKL runs userspace apps in ring 0. It discards hardware protection mechanisms in order to make processes run faster, decrease boot time, and decrease management overhead.
