Same. Or how they were picked. I kept scratching my head all evening cause I haven't made any updates or contributions to mine in quite a while.
- capnproto/capnproto
- sandstorm-io/sandstorm
- erlang/otp
(I don't remember the order).
I actively contribute heavily to sandstorm. I've sent patches here and there to capnproto, and it's vaguely a sister project to sandstorm. Those are probably some of the most popular projects I have multiple contributions to, though there are others.
otp feels a bit odd though, if there's and "and more" -- I sent them a one line patch to fix a build error when building against musl. I haven't really been involved since, nor was I before. But it's a high profile project.
