(from: Mineos-ruby megathread)
I see your point, and since -node is the one in production now we should at least make sure it stays stable and up to date, which is what is mostly what is done now. That being said. MineOS-node is starting to grow old, and has quite a lot of dependencies to old versions of node modules. There has been some effort done to update as far as possible, but to get all node dependencies up to date demands a rather large rewrite of the codebase.
MineOS ruby built on another arcitecture-idea with more enterprice-like functions, like being able to have a MineOS frontend server, with backend servers taking care of the different Minecraftservers, and has better support for different minecraft server types. Depending on @hexparrots wishes I would say that getting ruby up is probably the best used effort? This is based on my feeling that updating and adding funcitons to node would mean more or less a total rewrite anyway.
