If you want to improve significantly, go read someone else’s code and modify it. Try to fix a bug in a program you use, add a feature you want that doesn’t exist already, or even just do something simple for the sake of proving to yourself that you can do it – like compiling it from source and figuring out how to change some small snippet of text in a message box. Even if you don’t succeed, if you put in a serious effort attempting it, you will almost certainly learn a lot from trying.
Edit: changed wording to try to be clearer
Back before kbin fell off the internet it had a really neat experimental “collections” feature that would let you make named groups of communities. Collections could be used either privately or made public so other people could subscribe to your curated feed on a topic. The owner could update the collection as needed (e.g. adding or removing communities/magazines as they changed over time).
It’s one of the kbin features I miss most on lemmy.
Does anyone know if mbin ever got a copy of that? I know they forked off before it was added to kbin, but I don’t know if it ever got integrated later. (I don’t see it from a quick glance at moist and fedia, but I haven’t dug into the dev history.)
