I mean like running their hypothetical control software/framework within a docker on a local server. Is that illogical? I do the same for the software that runs my ip cameras with my home server, instead of them needing to connect to some external server.
You’re ultimately right though, when it comes to docker I am at the proficiency level of “can deploy other people’s images” and not so much on the “have bothered to make my own”
Depends on the program. Diploma mills for graduate degrees absolutely exist but many are extremely competitive.
