Project mention: What We Talk About When We Talk About Sideloading | news.ycombinator.com | 2025-10-28Tangent about open source development
As a person that tried the Pine64 ecosystem and not being able to will drivers/C++ apps into existence (like I can with web/cross platform), I did not contribute much other than buying the device/doing some videos on YT. (I bought: PP, PPP, PineBook, PineNote, PineTab)
It depended on few people working on it eg. through Discord communities
Anyway point is I saw Expensify I think they have these GitHub PRs which have $ values on them, would be interesting to take that approach, just pay for it literally eg. a GoFundMe for a feature.
ex. https://github.com/Expensify/App/issues/73681
