My strategy is to always install program with flatpak, SDKs are also installed as flatpak, find graphical alternatives to command line programs. I don’t use command line a lot, so I don’t need fancy tools for it.

I only have one system package installed for inputting unicode math symbols. So that I have a clean and easily migratable system.

I might add, everyway actually seek to “consolidate” all the older ways, and always ends up adding to the ways needing to be consolidated.

Installing on a old laptop is great because eventually after you get a more serious machine, you probably got enough experience to choose your distros.

Linux mint is certainly the most promising option, especially if you are just using the laptop, and don’t have any external monitors setup.
