Kotlin and preferably not Android related - there's soooo much Android focus on Kotlin I've stopped reading most of what I come across. I understand that mobile is where the focus is nowadays, but I'm doing microservices (in Spring - which has great Kotlin support now) and it's difficult to find new tips and techniques that aren't mobile specific. Even if the articles have concepts that are generic enough they'd be useful, I either skip it because it's targeted at mobile or I spin my wheels trying to figure out how to generalize it.
And I know someone in this thread specifically asked for more just and typescript; I'm hoping for less of that myself (sorry!) - it seems like every article I come across that's not for mobile is for front-end UI or Node. (Or python/data science/machine learning). I get that those are all the latest buzzwords, so that's what people want to write about, but it's getting to where I almost hate trying to surf here and other communities.
