Have a look at DietPi. That is a single-board-computer optimized Linux distribution that, in contradiction to what the name might suggest, runs on (almost) all of the SBC’s out there. It has stripped away all the things you don’t need and only installs and loads what is needed to run the software you choose, resulting in a very lightweight but powerful operating system for these kinds of devices. It has its own software catalog with a broad selection of optimized software, but you can of course install anything you want. Ive been running this on a Raxda Rock4 without any problems, and would definitely suggest this even on a Raspberry over the regular Pi image.

I’d say I understand most, except maybe some specific terminology that is less common. And things like sayings might sometimes throw me off-guard because while I can translate them, I can not always figure out what they mean. Accents and dialects can be tricky sometimes, just like when the speech is a bit faster than I’m used to. But overall I’d say I’m fine. I’m also lazy though, so I just read the subtitles whenever I can 🙂

Small note though: my high school offered bilingual education, so about half of the subjects was given in English by native speakers and I did IB English exams, that helped a lot and I’m certain my English level is well above average because of that
