     * 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.

For tracing, I used "strace -f --output-separately --output=guava-test.trace --decode-fds=path,socket,dev --string-limit=255 --timestamps=format:time,precision:us --syscall-times --decode-fds=all --summary mvn test --log-file guava-test.log --debug  -o -Dorg.slf4j.simpleLogger.showDateTime=true -Dorg.slf4j.simpleLogger.dateTimeFormat=HH:mm:ss,SSS".+    * I tried it overnight for Google Java Collection (https://github.com/google/guava.git).

     * Basically I traced everything I could. I also recorded the results of Maven, with timestamps so I could later relate that with the trace results. I took one hour to finish running (one order of magnitude slower than a typical run). I haven't analyzed the data yet, but I already noticed that Java uses fmutex extensively (which may be worth addressing later).     * Basically I traced everything I could.

 +  * 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''.
