The shell project: Fully assigned It's ready to go Lab 13: Another practice lab Nothing special to it Daemons! That'll be project 3 I'll make a video on making daemons, and the project It'll be more of a reminder than anything Because you'll want to start project 2 first However, about daemons: Origin of the name What they're used for "service" command Can we make one? How about an owlmon daemon? We can check dmesg Could also check a couple other places: pacmd list-sources / list-sinks I'm not sure that's going to be reliable here Used to use it for a different USB audio device lsusb Does it vanish right away, though? How will we raise an alarm? Audio: Audio comes through the owl There ARE other speakers, but are they on? Not a bad idea though Open a window: It'll appear on top, hopefully Could it appear as another tab in a browser? Check frequency: Doesn't need to be every millisecond Every hour is too infrequent We can pick a happy median Logging: Daemons often do this It's good to put the error messages somewhere!
