My dream in my spare time is just to work on OSS and sometimes I struggle to find projects that I want to contribute to and would rather start. I can’t seem to find any places outside of “bounty” type websites
https://concise-encoding.org is nearing release, but building the reference implementation (https://github.com/kstenerud/go-concise-encoding) has taken so much of my spare time that I couldn't even think about other languages (especially since I'll need to focus on the schema format next, and the proto-RPC protocol after that).
