If you’re doing it right, containers are less like VMs and more like cgroups. If orchestrated correctly it uses less system resources to run lots of services on a single system/node.
That said, I’m a devops/infrastructure/network professional and not a developer, so maybe I’m missing something from the dev experience… But I love containers.
Docker does kinda suck now, though. Use podman or another interface instead if you can help it.
There are huge archives of flash animations and you can install a safe “emulator” for playing flash that even runs in your browser. Look up Ruffle. I can’t remember the name of the big archive site I used, but it didn’t take much googling. I know I was able to find Homestar, Larry Carlson, Adam Phillips (bitey), joe cartoon and salad fingers as well as a ton of games from back in the day.
