     * Two models widely discussed are [[https://en.wikipedia.org/wiki/Abstract_state_machine | Abstract State Machines (ASM)]] and Event-B. There also some efforts on integrating domain knowledge (represented as ontologies) with state machines, which I find really nice. When designing and using LODM, I tried to use the conceptual model to ground the state machines and even to associate concepts to events (and, therefore, states transition).     * Two models widely discussed are [[https://en.wikipedia.org/wiki/Abstract_state_machine | Abstract State Machines (ASM)]] and Event-B.

     * Something we often struggle when defining the model is the specification. Currently we use UML, but there are alternatives.

I haven't analyzed the data yet, but I already noticed that Java uses fmutex extensively (which may be worth addressing later).

 +  * After updating Windows 10, grub disappeared. Apparently, Windows changed the default EFI boot manager. Fortunately, that is easy to fix. On a Windows terminal, as administrator, run: ''bcdedit /set {bootmgr} path \EFI\fedora\grubx64.efi''.
