Become a sponsor to CHIKAMATSU Naohiro
Sponsorship keeps me motivated. If someone sponsors me, it means my OSS was actually useful to them, and that's enough.
I use the money for server costs, technical books, and sometimes toys for my kid.
I've implemented features requested by sponsors before (when feasible), and I'm open to doing that again.
Most of my OSS is in Go. Recently I've been writing a lot of Gleam — 16+ packages on Hex: https://hex.pm/users/nao1215
